To Our Stockholders:

You are cordially invited to attend a special meeting of stockholders of Golden Minerals Company ("Golden") to be held at Courtyard by Marriott Denver West/Golden, 14700 W. 6th Avenue Frontage Road, Golden, Colorado 80401 on Tuesday, August 30, 2011 at 9:00 a.m., Denver time to consider and vote on the issuance of Golden shares in connection with the proposed "merger of equals" business combination transaction (the "Transaction") between Golden and ECU Silver Mining Inc. ("ECU"). The Transaction will be carried out by way of a plan of arrangement pursuant to the Business Corporations Act (Quebec) under which ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each ECU common share held immediately prior to the consummation of the Transaction. You will also be asked to consider and vote on a proposal to increase the authorized common stock of Golden following the Transaction from 50,000,000 shares to 100,000,000 shares. The increase in authorized capital will assist the combined company in future acquisition or financing transactions.

This merger of equals will be a transformative transaction for Golden and create a new junior silver mining company with a diversified portfolio of assets including ECU's silver, gold and base metals mines and exploration projects in the Velardeña Mining District, Durango, Mexico; Golden's El Quevar advanced silver exploration project in the Salta Province, Argentina; and Golden's Zacatecas silver exploration project in Zacatecas, Mexico. In evaluating and approving the Transaction, Golden's board of directors considered a number of factors including, among others:

•: Portfolio Growth—The Transaction will provide Golden, through ECU's Velardeña project, with exposure to ECU's position in one of Mexico's most prolific silver belts, and a producing mine with significant potential growth prospects.
•: Value Creation—The Transaction is expected to allow Golden to leverage its existing cash position by supporting the further development and expansion of exploration and production at ECU's Velardeña Properties.
•: Unification of Complementary Management Teams—Golden and ECU have complementary management teams with proven successful track records that are expected to allow the combined company to optimize existing exploration and development plans and mining operations. Upon completion of the Transaction, management will have a significant depth of experience in exploration, resource conversion, project development, and mining of both open pit and underground operations.
•: Geographic Diversification—The Transaction increases asset and geographic diversification benefits for Golden with production in Mexico and advanced exploration properties in Argentina, Mexico and Peru.
•: Increased Scale—The Transaction will create a combined company with greater scale, financial strength and an enhanced capital markets profile, with available funds to continue to advance expansion plans at Velardeña and the exploration of the El Quevar project. The Transaction will also provide Golden with exposure to new investors and is expected to improve the company's access to global capital markets to assist future growth objectives.

Table of Contents

•: Increased Portfolio of Silver Assets—The Transaction continues the strategy that Golden is currently pursuing of building a portfolio of quality silver producing assets in low political risk jurisdictions.

The Sentient Group, one of Golden's largest stockholders with approximately a 19% ownership stake, has indicated to Golden that it supports and intends to vote in favor of the proposed Transaction. Sentient has also expressed an interest in investing further capital in the combined company to retain its current proportionate ownership, although no agreement has been reached.

Your vote is very important. We cannot complete the Transaction unless the Golden common stockholders vote to approve the issuance of Golden common stock in connection with the Transaction, and it is important for our future flexibility in pursuing growth and financing opportunities that Golden stockholders approve the increase in our authorized common stock.

The board of directors hopes that you will attend the special meeting. However, whether or not you plan to attend the meeting, please sign, date and return the accompanying proxy card in the enclosed postage paid pre-addressed envelope, or otherwise return your proxy in a manner described in the accompanying proxy card, as soon as possible. Your vote is important, regardless of the number of shares you own, so please return your proxy card TODAY.

All of us at Golden Minerals appreciate your continued support, and look forward to seeing you at the special meeting.


		Sincerely,

		Jeffrey G. Clevenger Chairman of the Board, President and Chief Executive Officer

CAUTIONARY NOTE TO UNITED STATES STOCKHOLDERS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES

The terms "mineral resource," "measured mineral resource," "indicated mineral resource" and "inferred mineral resource" that are used in this proxy statement are defined in Canadian National Instrument 43-101—Standards of Disclosure for Mineral Projects ("NI 43-101"). These Canadian terms are not recognized under Securities and Exchange Commission ("SEC") Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC by U.S. registered companies. Under SEC disclosure standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. In addition, disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, stockholders are cautioned that the information contained in this proxy statement regarding ECU describing "mineral resources" is not directly comparable to information made public by U.S. companies subject to reporting requirements under U.S. securities laws. Stockholders are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically minable.

CAUTIONARY STATEMENTS CONCERNING FORWARD-LOOKING INFORMATION

Some information contained in or incorporated by reference into this proxy statement may contain forward-looking statements. These statements include statements in respect of the expected timing and anticipated benefits of the proposed business combination transaction between Golden and ECU (the "Transaction") and statements regarding future operations and activities of ECU, Golden or the combined company, including planned and potential exploration and development opportunities of the combined company, plans, expectations and assumptions concerning the El Quevar project or the Velardeña project, the timing and budget for exploration of our portfolio of exploration properties, our expected cash needs, and statements concerning our financial condition, operating strategies and operating and legal risks. There are also risks inherent in the nature of the proposed Transaction, including risks regarding the integration of the two entities, incorrect assessments of the values of the other entity, and failure to obtain the required securityholder, court, regulatory and other third party approvals.

This proxy statement also includes forward-looking statements relating to the potential for further investment by The Sentient Group in the combined company. Golden and ECU caution investors that no agreement with respect to such further investment has been reached and provide no assurance that any such agreement will be reached.

We use the words "anticipate," "continue," "likely," "estimate," "expect," "may," "could," "will," "project," "should," "believe" and similar expressions to identify forward-looking statements. Statements that contain these words discuss our future expectations, contain projections or state other forward-looking information. Although we believe the expectations and assumptions reflected in these forward-looking statements are reasonable, we cannot assure you that these expectations and assumptions will prove to be correct. The actual results of the combined company could differ materially from those expressed or implied in these forward-looking statements as a result of various risks, including the risk factors described in this proxy statement beginning on page 14, the risk factors

Table of Contents

set forth in our annual report on Form 10-K, and the risk factors set forth in ECU's annual information form, including:

•: Results of future exploration at Golden's El Quevar project;
•: The feasibility and economic viability of potential expansion plans at ECU's Velardeña project;
•: The feasibility and economic viability of Golden's El Quevar project;
•: The combined company's ability to raise necessary capital to complete expansion plans at ECU's Velardeña project and if justified by results the development of Golden's El Quevar project;
•: The combined company's ability to retain key management and mining personnel necessary to successfully operate and grow our business;
•: Worldwide economic and political events affecting the market prices for silver and other minerals which may be found on our exploration properties; and
•: Political and economic instability in Argentina, Mexico, Peru, and other countries in which we conduct our business, and future actions of the governments in such countries with respect to nationalization of natural resources or other changes in mining or taxation policies.

Many of those factors are beyond our ability to control or predict. You should not unduly rely on any of our forward-looking statements. These statements speak only as of the date of this proxy statement. Except as required by law, we are not obligated to publicly release any revisions to these forward-looking statements to reflect future events or developments. All subsequent written and oral forward-looking statements attributable to us and persons acting on our behalf are qualified in their entirety by the cautionary statements contained in this section and elsewhere in this proxy statement.

No person has been authorized by Golden to give any information or to make any representation in connection with the proposed business combination transaction or any other matters described herein other than as contained in this proxy statement and, if given or made, any such information or representation should be considered not to have been authorized by Golden or ECU.

Table of Contents

QUESTIONS AND ANSWERS ABOUT THE TRANSACTION AND THE SPECIAL MEETING

The following questions and answers briefly address some commonly asked questions about the Transaction and the special meeting. You should carefully read this entire proxy statement, including the attached Annexes. Capitalized terms in this proxy statement have the meanings set out in the Glossary of Terms attached as Annex A or in the proxy statement.

Q: What is Golden proposing?

A:: Golden stockholders are being asked to consider and vote upon two proposals. First, Golden stockholders will vote upon a proposal approving the issuance of Golden common stock in connection with a business combination transaction pursuant to which Golden will acquire all of ECU's outstanding common shares and convertible securities and ECU will become a wholly-owned subsidiary of Golden. The Transaction will be carried out pursuant to (i) an arrangement agreement dated June 24, 2011, between Golden and ECU, which we refer to as the "Arrangement Agreement," and (ii) a court-approved plan of arrangement under Chapter XVI—Division II of the Business Corporations Act (Québec), which we refer to as the "Plan of Arrangement." The Arrangement Agreement and Plan of Arrangement provide that ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each ECU common share held immediately prior to the consummation of the Transaction. In addition, upon the consummation of the Transaction, new Golden options to purchase Golden common stock, or "Golden Replacement Options," will be exchanged for all outstanding options to purchase ECU common shares, and new Golden warrants to purchase Golden common stock, or "Golden Replacement Warrants," will be exchanged for all outstanding warrants to purchase ECU common shares. It is anticipated that consummation of the Transaction pursuant to the Plan of Arrangement will result in Golden paying an aggregate of approximately Cdn$125,000 in cash and issuing a total of approximately 16.0 million new shares, not including up to approximately 2.9 million new shares that will be issuable following the exercise of currently outstanding ECU options and warrants (or upon the exercise of the Golden Replacement Options and Golden Replacement Warrants to be received in exchange therefor) and approximately 167,000 shares that are expected to be issued, in the aggregate, in satisfaction of certain ECU change of control payments.

In addition, Golden stockholders will vote upon a proposal to amend Golden's certificate of incorporation to increase the authorized number of shares of Golden common stock from 50,000,000 to 100,000,000. The approval of this proposal is not a condition to the closing of the Transaction.

Q: How does the board of directors recommend that I vote?

A:

Golden's board of directors unanimously recommends that Golden's stockholders vote:

•: FOR the issuance of Golden common stock (including stock issuable upon exercise of Golden Replacement Options and the Golden Replacement Warrants) in connection with the Transaction, which we refer to as the "Share Issuance Proposal;" and
•: FOR the adoption of the amendment to Golden's certificate of incorporation to increase the authorized number of shares of Golden's common stock, which we refer to as the "Charter Amendment Proposal."

Q: Why is Golden proposing to combine with ECU?

A:: Golden is proposing to combine with ECU because Golden believes that the Transaction will create a combined company with an attractive and more diversified portfolio of assets, greater scale and financial strength, and an enhanced capital markets profile. We believe that the

Table of Contents

combined company will be sufficiently capitalized to advance expansion plans at ECU's Velardeña project and the exploration of Golden's El Quevar project, and that combining the complementary management teams of the two companies will provide the broad experience and expertise necessary to lead these efforts. For additional information regarding ECU's Velardeña project and Golden's El Quevar project, see "Information Concerning ECU" and "Information Concerning Golden," beginning on pages 75 and 69, respectively.

Q: Why is Golden proposing to amend its certificate of incorporation?

A:: Golden is proposing to amend its certificate of incorporation because, while an increase in authorized shares is not necessary to enable Golden to complete the Transaction, the increase will provide the Golden board with additional capacity to issue shares in future offerings or acquisitions following consummation of the Transaction as determined by Golden's board to be in the best interests of Golden's stockholders. The approval of the Charter Amendment Proposal is not a condition precedent to the consummation of the Transaction. Moreover, if the Share Issuance Proposal is not approved or the Transaction is not consummated for any reason, Golden will not amend its certificate of incorporation even if the Charter Amendment Proposal is approved.

Q: Are there risks I should consider in deciding whether to vote for the Share Issuance Proposal?

A:: Yes. The Share Issuance Proposal and the Transaction are subject to a number of risks and uncertainties. Golden may not realize the benefits it currently anticipates from the Transaction due to the challenges associated with integrating the companies and other risks inherent in its mining business. See "Risk Factors" beginning on page 14.

Q: Am I entitled to dissenters' appraisal rights?

A:: No. Holders of Golden shares are not entitled to dissenters' appraisal rights in connection with the Transaction or any other action to be taken at the special meeting. See "General Information Concerning the Golden Meeting—Dissent Rights" beginning on page 29.

Q: How does Golden intend to finance the Transaction?

A:: The consideration to be paid by Golden in the Transaction consists primarily of Golden common stock. In addition, Golden will pay cash consideration of Cdn$0.000394 for each ECU share outstanding (an aggregate of approximately Cdn$125,000), with all such payments made from available cash on hand.

Q: When do Golden and ECU expect to complete the Transaction?

A:: Golden and ECU expect to complete the Transaction when all of the conditions to completion of the Transaction have been satisfied or waived. The parties are working toward satisfying these conditions and completing the Transaction as quickly as possible. The parties currently plan to complete the Transaction on or about September 2, 2011.

Q: What is the role of Canadian courts with respect to the Transaction?

A:: Under the Business Corporations Act (Québec), a Québec court must approve the Plan of Arrangement. If ECU Securityholders approve the Transaction and Golden Stockholders approve the issuance of Golden common stock to be issued pursuant to the Transaction, the Superior Court of Québec will hold a hearing regarding a final order to approve the Plan of Arrangement and any amendments thereto made in accordance with the Arrangement Agreement. The court will consider, among other things, the fairness and reasonableness of the Plan of Arrangement. The

Table of Contents

court may approve the Plan of Arrangement in any manner and subject to compliance with such terms and conditions, if any, as the court may direct. The court's approval of the fairness of the Plan of Arrangement will serve as the basis for an exemption from the registration requirements of the United States Securities Act of 1933, as amended, or the "Securities Act," for the issuance of the Golden common stock, the Golden Replacement Options and the Golden Replacement Warrants to the ECU shareholders, optionholders and warrantholders, as applicable, in connection with the Plan of Arrangement and the Arrangement Agreement.

Q: What will the share ownership, board of directors and management of Golden look like after the combination?

A:: We estimate that upon completion of the Transaction, former shareholders of ECU will own approximately 51% of the outstanding common stock of Golden, assuming that no outstanding ECU options or warrants are exercised before the consummation of the Transaction. If all of those options and warrants are exercised before the consummation of the Transaction, former securityholders of ECU will own approximately 55% of the outstanding stock of Golden. Upon consummation of the Transaction, we expect that we will expand the size of our board of directors in order to add one current ECU director, Michael T. Mason, to our board. In addition, it is our intention that ECU's current President, Stephen J. Altmann, will become the President of Golden after the Transaction. Golden's current Chairman and CEO, Jeffrey G. Clevenger, will retain these positions following the Transaction.

Q: Why am I receiving this proxy statement?

A:: You are receiving this proxy statement and enclosed proxy card because, as of July 29, 2011, the record date for the special meeting, you owned shares of Golden common stock. Only holders of record of Golden common stock as of the close of business on July 29, 2011 will be entitled to vote those shares at the special meeting. Our board of directors is providing these proxy materials to give you information to determine how to vote in connection with the special meeting of our stockholders.

This proxy statement describes the proposals on which we would like you, as a stockholder, to vote. It also provides you with important information about these proposals to enable you to make an informed decision as to whether to vote your shares of Golden common stock to approve the matters described herein.

Your vote is very important and we encourage you to complete, sign, date and mail your proxy card, as soon as possible, whether or not you plan to attend the special meeting. Convenient telephone and Internet voting options are also available.

Q: When and where is the special meeting?

A:: The special meeting will be held at Courtyard by Marriott Denver West/Golden, 14700 W. 6th Avenue Frontage Road, Golden, Colorado 80401 on Tuesday, August 30, 2011 at 9:00 a.m., Denver time.

Q: What vote is required to approve the proposals?

A:: The Share Issuance Proposal must be approved by the affirmative vote of a majority of the shares of Golden common stock present at the special meeting and entitled to vote thereon, assuming a quorum is present.

The Charter Amendment Proposal must be approved by the affirmative vote of a majority of the outstanding shares of Golden common stock.

Table of Contents

Q: What constitutes a quorum at the special meeting?

A:: The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Golden common stock entitled to vote at the special meeting constitutes a quorum for the transaction of business at the special meeting. If you hold your shares through a broker or bank, and your broker or bank votes your shares on the Charter Amendment Proposal, those shares will be counted for purposes of determining the presence of a quorum at the meeting.

Q: How many votes do I have?

A:: You have one vote for each share of Golden common stock that you own as of the record date.

Q: How are votes counted?

A:: Votes will be counted by the inspector of election appointed for the special meeting, who will separately count "For" and "Against" votes, abstentions and broker non-votes. A "broker non-vote" occurs when a nominee holding shares for a beneficial owner does not receive instructions from the beneficial owner with respect to proposals relating to non-routine matters. The Share Issuance Proposal is considered a non-routine matter and the Charter Amendment Proposal is considered a routine matter.

Q: How do I vote my Golden common stock?

A:: Before you vote, you should read this proxy statement in its entirety, including its Annexes, and carefully consider how the Transaction affects you. If you are a stockholder of record, you should mail your completed, dated and signed proxy card in the enclosed return envelope or submit your proxy by telephone or over the Internet as soon as possible so that your shares can be voted at the special meeting. For more information on how to vote your shares, see the section entitled "How You Can Vote."

If you hold your Golden common stock in "street name," you should follow the voting directions provided by your bank, brokerage firm or other nominee. You may complete and mail a voting instruction form to your bank, brokerage firm or other nominee or, in most cases, submit voting instructions by telephone or over the Internet to your bank, brokerage firm or other nominee. If you provide specific voting instructions by mail, telephone or the Internet, your bank, brokerage firm or other nominee will vote your shares of common stock as you have directed. Please note that if you wish to vote in person at the special meeting, you must obtain a "legal" proxy from your bank, brokerage firm or other nominee. If you do not provide your bank, brokerage firm or other nominee with voting instructions, your shares held through such entity will not be voted.

Q: What happens if I do not vote?

A:: If you do not vote, your shares will not be counted toward the approval requirement for the Share Issuance Proposal. If you hold your shares through a broker, your broker may vote your shares on the Charter Amendment Proposal. Broker non-votes, if any, will have no effect on the Share Issuance Proposal but will have the same effect as a vote "AGAINST" the Charter Amendment Proposal. Abstentions will have the same effect as a vote "AGAINST" the Share Issuance Proposal and the Charter Amendment Proposal.

Q: What happens if I don't indicate how to vote on my proxy?

A:: If you are a record holder of Golden common stock and sign and send in your proxy card, but do not include instructions on how to vote, your shares will be voted "FOR" the Share Issuance Proposal and "FOR" the Charter Amendment Proposal. Golden's management does not currently

Table of Contents

intend to bring any proposals to the special meeting other than those described in this proxy statement. If other proposals requiring a vote of stockholders are properly brought before the special meeting, the persons named in the enclosed proxy card intend to vote the shares they represent in accordance with their best judgment.

Q: What happens if I sell my shares of Golden common stock before the special meeting?

A:: The record date for stockholders entitled to vote at the special meeting is earlier than the date of the special meeting. If you transfer your shares of Golden common stock after the record date but before the special meeting, you will, unless special arrangements are made, retain your right to vote at the special meeting.

Q: If my shares are held in "street name" by my broker, will my broker vote my shares for me?

A:: If your shares are held through a broker, bank or other nominee (collectively referred to as "brokers"), under applicable rules of NYSE Amex LLC ("NYSE Amex") (one of the exchanges on which our common stock is traded), the broker will vote your shares according to the specific instructions it receives from you. If the broker does not receive voting instructions from you, the broker may vote only on a proposal that is considered a "routine" matter under the NYSE Amex rules. At the special meeting, your broker may vote without your instructions only on the Charter Amendment Proposal, because it is considered a routine matter. Your broker may not vote on the Share Issuance Proposal because it is non-routine. The broker's failure to vote on the Share Issuance Proposal because it lacks discretionary authority to do so, commonly referred to as a "broker non-vote," will not affect the outcome of the vote on the Share Issuance Proposal. Any broker non-votes will have the same effect as a vote "AGAINST" the Charter Amendment Proposal.

Q: Will my shares held in "street name" or another form of record ownership be combined for voting purposes with shares I hold of record?

A:: No. Because any shares you may hold in "street name" will be deemed to be held by a different stockholder than any shares you hold of record, shares held in "street name" will not be combined for voting purposes with shares you hold of record. Similarly, if you own shares in various registered forms, such as jointly with your spouse, as trustee of a trust or as custodian for a minor, you will receive, and will need to sign and return, a separate proxy card for those shares because they are held in a different form of record ownership. Shares held by a corporation or business entity must be voted by an authorized officer of the entity. Shares held in a retirement investment account must be voted under the rules governing the account.

Q: What does it mean if I receive more than one set of materials?

A:: This means you own shares of Golden common stock that are registered under different names. For example, you may own some shares directly as a stockholder of record and other shares through a broker or you may own shares through more than one broker. In these situations, you will receive multiple sets of proxy materials. You must vote, sign and return all of the proxy cards or follow the instructions for any alternative voting procedure on each of the proxy cards that you receive in order to vote all of the shares you own. Each proxy card you receive comes with its own prepaid return envelope. If you vote by mail, make sure you return each proxy card in the return envelope that accompanies that proxy card.

Table of Contents

Q: May I vote in person?

A:: Yes. You may attend the special meeting and vote your shares in person whether or not you sign and return your proxy card. If your shares are held of record by a broker, bank or other nominee and you wish to vote at the special meeting, you must obtain a "legal" proxy from the record holder.

Q: May I change my vote after I have mailed my signed proxy card?

A:

Yes. You may revoke and change your vote at any time before your proxy card is voted at the special meeting. You can do this in one of three ways:

•: First, you can send a written notice to the Golden corporate secretary stating that you would like to revoke your proxy;
•: Second, you can complete and submit a new proxy in writing, by telephone or over the Internet; or
•: Third, you can attend the meeting and vote in person. Your attendance alone will not revoke your proxy.

If you have instructed a broker to vote your shares, you must follow directions received from your broker to change those instructions.

Q: Who can help answer my questions?

A:: If you have questions about the Transaction and the special meeting, including the procedures for voting your shares, you should contact our proxy solicitor, Morrow & Co., LLC, toll-free at 1-877-705-9707.

SUMMARY

The following information is a summary of certain information contained in this proxy statement. The information contained in this summary should be read in conjunction with, and is qualified in its entirety by, the more detailed information and financial data and statements contained elsewhere in this proxy statement, including the Annexes and the documents incorporated by reference. Capitalized terms in this Summary have the meanings set out in the Glossary of Terms attached as Annex A or as set out in this Summary.

The Transaction

Golden and ECU are proposing to engage in a business combination transaction pursuant to which Golden will acquire all of the outstanding common shares, options and warrants of ECU, and ECU will become a wholly-owned subsidiary of Golden. The Transaction will be carried out pursuant to (i) the Arrangement Agreement dated June 24, 2011, between Golden and ECU, and (ii) a Court-approved arrangement under Chapter XVI—Division II of the Business Corporations Act (Québec), which we refer to as the "Plan of Arrangement". The Arrangement Agreement and Plan of Arrangement provide that ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each ECU common share held immediately prior to the consummation of the Transaction. In addition, upon the consummation of the Transaction, new Golden options to purchase Golden common stock, or "Golden Replacement Options," will be exchanged for all outstanding options to purchase ECU common shares, and new Golden warrants to purchase Golden common stock, or "Golden Replacement Warrants," will be exchanged for all outstanding warrants to purchase ECU common shares. It is anticipated that consummation of the Transaction pursuant to the Plan of Arrangement will result in Golden paying an aggregate of approximately Cdn$125,000 in cash, and issuing a total of approximately 16.0 million new shares, not including up to approximately 2.9 million new shares that will be issuable following the exercise of currently outstanding ECU options and warrants (or upon the exercise of the Golden Replacement Options and Golden Replacement Warrants to be received in exchange for those options and warrants) and approximately 167,000 shares that are expected to be issued, in the aggregate, in satisfaction of certain ECU change of control payments.

See "The Transaction" beginning on page 30.

General Information Concerning the Golden Stockholders Meeting

Date, Time and Place of the Meeting

The Golden stockholders' vote will take place at a special meeting to be held at Courtyard by Marriott Denver West/Golden, 14700 W. 6th Avenue Frontage Road, Golden, Colorado 80401 on Tuesday, August 30, 2011 at 9:00 a.m., Denver time.

Record Date for the Golden Stockholders Meeting

You are entitled to vote at the special meeting if you owned Golden common stock at the close of business on July 29, 2011.

Purpose of the Golden Stockholders Meeting

Golden's stockholders are being asked to consider and vote upon:

(i): a proposal approving the issuance of shares of Golden common stock, par value $0.01 per share, (including stock issuable upon exercise of the Golden Replacement Options and Golden Replacement Warrants) in connection with the Transaction (this proposal is referred to as the "Share Issuance Proposal"); and
(ii): a proposal to amend Golden's certificate of incorporation to increase the authorized number of shares of Golden common stock from 50,000,000 to 100,000,000 (this proposal is referred to as the "Charter Amendment Proposal").

Approval of the Share Issuance Proposal is required to enable Golden to complete the Transaction. Approval of the Charter Amendment Proposal is not required to complete the Transaction. Approval of the Charter Amendment Proposal is being solicited in order to provide the Golden board with additional capacity to issue shares in future offerings or acquisitions following consummation of the Transaction as determined by the Golden board to be in the best interests of the Golden stockholders. See "General Information Concerning the Golden Meeting" beginning on page 26.

Table of Contents

Required Vote of Golden's Stockholders

The Share Issuance Proposal must be approved by the affirmative vote of a majority of the shares of Golden common stock present at the special meeting and entitled to vote thereon, assuming a quorum is present. The Charter Amendment Proposal must be approved by the affirmative vote of a majority of the outstanding shares of Golden common stock. Abstentions will have the same effect as a vote "AGAINST" the Share Issuance Proposal and the Charter Amendment Proposal. Shares held through brokers may be voted without instruction by such brokers on the Charter Amendment Proposal but not the Share Issuance Proposal. A broker's failure to vote on the Share Issuance Proposal because it lacks discretionary authority to do so, commonly referred to as a "broker non-vote," will not affect the outcome of the vote on the Share Issuance Proposal.

Golden's Board Recommendation

Golden's board of directors unanimously recommends that Golden's stockholders vote "FOR" the Share Issuance Proposal and "FOR" the Charter Amendment Proposal.

Opinion of Golden's Financial Advisor

On June 23, 2011 Golden's board of directors received an opinion from BMO Capital Markets Corp. to the effect that, as of June 23, 2011, and subject to the various assumptions in the opinion, the exchange ratio, together with the cash consideration payable in the Transaction, was fair, from a financial point of view, to Golden.

See "Fairness Opinion of Financial Advisor to Golden" beginning on page 37.

Québec Court Approval

Under the Business Corporations Act (Québec), the Transaction requires court and ECU securityholder approval. On July 14, 2011, ECU obtained an interim order from the Superior Court of Québec (the "Québec Court") providing for the calling and holding of the ECU special meeting and other procedural matters. Subject to receipt of the requisite approvals of the Transaction by securityholders of ECU and Golden at their respective special meetings, the hearing in respect of a final order from the Québec Court is expected to take place on or about August 31, 2011.

Anticipated Closing of the Transaction

Golden and ECU will complete the Transaction when all of the conditions to completion of the Transaction have been satisfied or waived. The parties are working toward satisfying these conditions and completing the Transaction as quickly as possible. The parties currently plan to complete the Transaction on or about September 2, 2011, although there can be no assurance that the Transaction will be completed by this date, or at all.

Post-Transaction Governance

Upon consummation of the Transaction, Golden plans to increase the size of its board of directors in order to add one current ECU director, Michael T. Mason, to the Golden board. In addition, ECU's current President, Stephen J. Altmann, is expected to become the President of Golden after the Transaction. Golden's current Chairman and CEO, Jeffrey G. Clevenger, will retain those positions in Golden following the Transaction.

See "Directors and Officers of the Combined Company" beginning on page 62.

U.S. Federal Income Tax Consequences

There are no material U.S. federal income tax consequences to Golden's current stockholders that will result from Golden's acquisition of ECU or the issuance of Golden common stock pursuant to the Transaction.

Private Placement Transaction

On June 24, 2011, Golden and ECU entered into the subscription agreement, pursuant to which ECU issued to Golden on July 13, 2011 Cdn$15.0 million principal amount 0.0% senior unsecured convertible notes in a private placement. The private placement is intended to provide ECU with interim financing of its operations pending consummation of the Transaction. The convertible notes will mature on June 30, 2012 (subject to extension as described below), and will be convertible by Golden at any time prior to 5:00 p.m. (Toronto time) on June 29, 2012 into ECU Shares at the rate of 1,032 shares per Cdn$1,000 principal amount, consistent with the exchange ratio. The convertible notes will also be redeemable by ECU at any time after the record date for the special meeting of ECU Shareholders to approve the Transaction and prior to the maturity date, at 100% of the face value of the notes plus accrued and unpaid interest. ECU may elect to extend the maturity of the convertible notes to December 31, 2012 for a cash payment equal to 4% of the face value of the then outstanding notes, payable on the day the extension option is exercised, with interest accruing on the notes at 10% per annum during such extension period. Under the terms of the subscription agreement, the proceeds of the private placement are held in an escrow account and may be used only for certain specified purposes. As of July 13, the shares issuable upon conversion of the convertible notes represented approximately 4.7% of ECU's common shares outstanding on an as-converted basis.

Golden, as holder of the convertible notes, is entitled to vote any ECU common shares received upon conversion of the Notes. Further, Golden may vote the convertible notes themselves in any vote of ECU's outstanding common shares, options, warrants and convertible securities voting as a single class, with respect to the vote of ECU Securityholders to approve the Transaction. See "The Transaction—Subscription Agreement and Private Placement" on page 34.

Risk Factors

There are certain risk factors relating to Golden, ECU and the Transaction which should be carefully considered by stockholders, including the fact that the Transaction may not be completed if, among other things, Golden or ECU securityholder approval is not obtained, or if any other conditions precedent to the completion of the Transaction are not satisfied or waived, as applicable.

See "Risk Factors" beginning on page 14.

RISK FACTORS

In addition to the other information contained in, or incorporated by reference into, this proxy statement (including the risk factors applicable to Golden contained under the heading "Risk Factors" in Golden's annual report on Form 10-K for the fiscal year ended December 31, 2010), the following factors should be considered carefully when considering risks related to the Transaction and the combined company. These risks and uncertainties are not the only risks Golden, ECU and the combined company may face, nor do they include all of the risks and uncertainties associated with the Transaction. If any such risks actually occur, the business, prospects, financial condition, cash flows and operating results of Golden, ECU and the combined company could be materially adversely affected. See "Where Stockholders Can Find More Information About Golden" beginning on page 95 for a list of the documents incorporated by reference.

Risks Related to the Transaction

The Transaction will present challenges associated with integrating operations, personnel and other aspects of the companies and assumption of liabilities that may exist at ECU and which may be known or unknown by Golden.

The results of the combined company following the Transaction will depend in part upon Golden's ability to integrate its business with ECU's business in an efficient and effective manner. Golden's attempt to integrate two companies that have previously operated independently may result in significant challenges, and Golden may be unable to accomplish the integration smoothly or successfully. In particular, the necessity of coordinating geographically dispersed organizations and addressing possible differences in corporate cultures and management philosophies may increase the difficulties of integration. ECU has operated as a Québec corporation, with substantially all of its personnel and operations in Mexico, and Golden has not previously conducted mining operations in Mexico. The integration will require the dedication of significant management resources to become familiar with the Mexican operations and the culture of ECU, which may temporarily distract management's attention from the day-to-day operations of the businesses of the combined company. In addition, the combined company may adjust the way in which ECU has conducted its operations and utilized its properties, which may require retraining and development of new procedures and methodologies. The process of integrating operations and making such adjustments after the Transaction could cause an interruption of, or loss of momentum in, the activities of one or more of the combined company's businesses and the loss of key personnel. Employee uncertainty, lack of focus or turnover during the integration process may also disrupt the businesses of the combined company. Any inability of management to integrate the operations of Golden and ECU successfully could have a material adverse effect on the business and financial condition of the combined company.

In addition, the Transaction will subject Golden to any environmental, contractual or other obligations and liabilities of ECU, some of which may be unknown. While Golden and its legal and financial advisors have conducted due diligence on ECU and its business, there can be no assurance that Golden is aware of all obligations and liabilities of ECU. These liabilities, and any additional risks and uncertainties related to ECU's business and to the Transaction not currently known to Golden or that Golden may currently be aware of, but that prove to be more significant than assessed or estimated by Golden, could negatively impact the business, financial condition and results of operations of the combined company following consummation of the Transaction.

Golden will incur significant transaction, combination-related and restructuring costs in connection with the Transaction.

Golden and ECU expect to incur transaction fees and other expenses related to the Transaction totaling approximately $12.0 million, including financial advisors' fees, filing fees, legal and accounting fees, soliciting fees, regulatory fees and mailing costs. ECU expects to incur costs for executive bonuses

Table of Contents

and change of control payments related to the Transaction totaling approximately Cdn$4.0 million (some of which is expected to be paid in Golden common stock). Golden also expects to incur significant costs associated with combining the operations of the two companies. It is difficult to predict the amount of these costs before Golden begins the integration process. The combined company may incur additional unanticipated costs as a consequence of difficulties arising from efforts to integrate the operations of the two companies. Although Golden expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, can offset incremental transaction, combination-related and restructuring costs over time, Golden cannot assure that this net benefit will be achieved in the near term, or at all.

We may incur significant costs related to ECU's contractual arrangements that we don't currently anticipate.

We may incur significant costs related to ECU's contractual arrangements that we don't currently anticipate. For example, if the Transaction is completed, under certain circumstances ECU's term loan lender may terminate its contractual arrangements with ECU. Although ECU is attempting to obtain the consent of ECU's term loan lender to the transaction, ECU may not be successful in these efforts. If the Transaction is completed without the consent of ECU's term loan lender, we may be required, in certain circumstances, to immediately repay the full amount borrowed under the term loan facility (expected to be approximately $16.0 million at closing), plus certain other amounts. There may be other ECU agreements with similar provisions, contracts with respect to which there are disputes and contractual obligations of which we are not currently aware, any of which could impose unanticipated costs on the combined company following completion of the Transaction. If these events were to occur, the additional expenditures in connection with repayment of the term loan or other unanticipated costs would significantly reduce the amount of cash that we currently expect to have available for deployment at our El Quevar project, ECU's Velardeña properties, or other properties in our exploration portfolio on the schedule we currently anticipate.

The officers and directors of Golden and ECU may have interests that are different from the interests of Golden Stockholders.

Because current stockholders of ECU will own 51% of the Golden common stock after the Transaction (55% on a fully diluted basis), the Transaction constitutes a change of control under several significant agreements to which Golden is a party, which triggers certain rights and obligations under those agreements. Unvested awards under Golden's 2009 Equity Incentive Plan (including stock options, restricted stock and restricted stock units) will vest immediately upon closing of the Transaction. At the closing of the Transaction, current officers and directors of Golden will hold stock options to purchase 85,874 shares of common stock, and officers of Golden will hold 201,735 shares of restricted stock that would have vested on various dates between December 2011 and December 2013. Directors of Golden will hold 14,355 restricted stock units that would have vested during May 2012. In addition, Golden has change of control agreements with each of its executive officers that provide for severance benefits if, within two years of the closing of the Transaction, either the combined company terminates his or her employment without cause, or the officer terminates his or her employment for good reason. Although Golden does not currently anticipate that any such terminations will occur, if terminations of all the existing Golden executives were to occur, Golden's executives would be entitled to receive severance payments consisting of cash, tax reimbursement, and perquisites equal to approximately $9.9 million.

In addition, ECU will make bonus payments for successful completion of the Transaction to its executive officers totaling approximately Cdn$3.3 million (some of which is expected to be paid in Golden common stock) and severance payments to certain of its officers upon closing the Transaction totaling approximately Cdn$0.7 million.

Table of Contents

These payments and potential benefits give the directors and management of Golden and ECU an interest in the Transaction that differs from the interest of Golden Stockholders.

Golden Stockholders will suffer immediate and substantial dilution to their equity and voting interests as a result of the issuance of Golden common stock to the ECU stockholders.

In connection with the Transaction, Golden will issue approximately 16.0 million shares of common stock, which excludes up to 2.9 million new shares that will be issuable upon exercise of currently outstanding ECU warrants and options (or, following the Transaction, upon the exercise of the Replacement Options and Replacement Warrants issued in exchange for ECU warrants and options) and common stock expected to be issued in lieu of Cdn$2.75 million in transaction completion bonuses to Mr. Roy and Mr. Altmann. If all outstanding ECU options and warrants were exercised before the consummation of the Transaction, former ECU Shareholders would own approximately 55% of the outstanding stock of the combined company. Accordingly, the issuance of Golden common stock to ECU Shareholders will reduce the percentage of equity and voting interests held by each of Golden's current stockholders.

Golden has previously completed private placement transactions with Sentient Global Resources Fund III, LP and SGRF III Parallel I, LP (collectively, "Sentient") and Sentient has indicated a potential interest in further investing in the combined company in a private placement following consummation of the Transaction. The Transaction will increase the need of the combined company for additional financing to support the exploration and development of ECU's Velardeña properties in addition to Golden's historic properties. Because cash from operations is not expected to be sufficient to provide needed capital, and because debt financing is difficult to obtain for early stage mining operations, the likelihood is high that Golden would seek such financing in the equity markets. If the combined company were to engage in a private equity financing with Sentient or any other party, or engage in a public equity offering following the Transaction, current Golden Stockholders' ownership interest in the combined company would be further diluted.

Golden's common stock price could be depressed by sales of shares by ECU or Golden shareholders who sell their Golden shares.

Some ECU Shareholders may intend not to hold Golden common stock and some Golden Stockholders may decide to sell their shares following the Transaction, particularly if the market reaction to the Transaction is not favorable. If a significant number of Golden or former ECU Shareholders seek to sell their Golden common stock following completion of the Transaction, the trading price of Golden common stock may be adversely affected. A decrease in the trading price of the Golden common stock could impair the combined company's ability to raise capital through future sales of common stock.

The existence of a significant number of options and warrants may have a negative effect on the market price of Golden common stock.

ECU currently has outstanding ECU Options and ECU Warrants to purchase ECU Shares, which will, in the Transaction, be replaced by the Golden Replacement Options and Golden Replacement Warrants to purchase Golden common stock. The Golden Replacement Options will consist of employee options to purchase 661,750 shares of Golden common stock at exercise prices ranging from $16.00 to $31.80, and expiring between September 2011 and October 2014, and the Golden Replacement Warrants will consist of warrants to purchase 386,363 and 1,831,929 shares of Golden common stock, respectively, at exercise prices of $18.00 and $19.00, respectively, expiring in December 2011 and February 2014, respectively. The existence of securities available for exercise and resale is referred to as an "overhang", and, particularly if the options and warrants are "in the money", the

Table of Contents

anticipation of potential sales could exert downward pressure on the market price of Golden common stock.

Potential payments made to any dissenting ECU Shareholders in respect of their shares could exceed the amount of consideration otherwise due to them under the terms of the Arrangement Agreement.

Under the Business Corporations Act (Québec), ECU Shareholders will have the right to dissent with respect to the proposed Transaction. If any ECU Shareholders properly exercise their right to dissent, such ECU Shareholders will be entitled to be paid the judicially determined fair value of their ECU Shares. While Golden and ECU believe that the value of the consideration to be paid to ECU Shareholders pursuant to the Transaction is equal to or exceeds the fair value of the ECU Shares, there can be no assurance that a court would agree with this assessment and consequently the amount any dissenting ECU Shareholders receive could be higher than the consideration to which those shareholders would have been entitled under the Arrangement Agreement. In addition, Golden may be required to pay dissenting ECU Shareholders all or a portion of the judicially determined value of their ECU Shares in cash, which would reduce the cash available to the combined company for advancement of the El Quevar project, expansion efforts at the Velardeña properties and advancement of the combined company's other exploration properties. A condition to closing in the Arrangement Agreement is that holders of no more than 5% of ECU's shares have exercised dissent rights, but Golden could waive this condition.

ECU's public filings are subject to Canadian disclosure requirements, which differ from SEC requirements.

ECU is a Canadian issuer that is required to prepare and file its periodic and other filings in accordance with Canadian disclosure requirements. As a result, certain of the information about ECU that is contained in this proxy statement was prepared with a view to compliance with Canadian GAAP or IFRS and Canadian disclosure regulations, rather than the requirements that would apply in the United States. Because Canadian disclosure requirements are different from SEC requirements, the information about ECU contained in this proxy statement may not be comparable to similar information available about Golden or other U.S. issuers.

The presentation of historical financial statements of ECU will not be comparable to the presentation of ECU's financial results following completion of the Transaction.

ECU has been a Québec corporation whose financial statements, until December 31, 2010, were prepared in accordance with Canadian GAAP, and since January 1, 2011, have been prepared in accordance with IFRS. After the Transaction, ECU will be a wholly-owned subsidiary of Golden, and its financial statements will be consolidated with those of Golden, and will be prepared in accordance with U.S. GAAP. Under Canadian GAAP and IFRS, ECU has been capitalizing exploration and development costs incurred during the development stage, including the operating expenses at its active mining operations, and offsetting those capitalized costs with revenue generated from saleable minerals. Under U.S. GAAP, those exploration and development costs would have appeared as expenses on the statement of operations and revenues generated during the development stage would have appeared as Other Income, Net of Incremental and Direct Costs Associated with the Revenue, on the statement of operations. If ECU had reported in U.S. GAAP for the fiscal year ended December 31, 2010, its net losses would have increased by approximately $2.5 million. Because of these and other differences, ECU's historical financial results will not be comparable to the results as they will appear in the consolidated financial statements of the combined company.

Table of Contents

Risks Relating to the Businesses of Golden, ECU and the Combined Company

After the completion of the Transaction, the business of the combined company, as well as the price of Golden common stock, will be subject to numerous risks currently affecting the businesses of Golden and ECU.

ECU and Golden have both historically incurred operating losses and operating cash flow deficits and we expect that the combined company will continue to incur operating losses in the foreseeable future.

ECU and Golden have a history of operating losses and we expect that the combined company will continue to incur operating losses unless and until such time as ECU's Velardeña Properties in Central Mexico, our El Quevar project in Argentina, or another of our exploration properties generates sufficient revenue to fund continuing operations of the combined company. None of Golden's properties is currently in commercial production. While ECU is currently in production at its Velardeña Properties, it is still considered to be a development stage company, as it has not determined that a sufficient portion of its mineral resources are economically exploitable and, accordingly, it has no mineral reserves. We do not expect that revenues generated by production at ECU's properties will exceed the expenses of the combined company for at least the next few years. In 2010, ECU suffered a decrease in cash during the year of Cdn$7.3 million, leaving cash and cash equivalents of only Cdn$344,826 at December 31, 2010, and Golden has purchased Cdn$15.0 million principal amount interest-free convertible notes from ECU to provide ECU with needed liquidity pending the closing of the Transaction. We expect the combined company's operating expenses, capital expenditures and other expenses will increase in future years as we advance exploration, development and commercial production of the combined company's properties and any other properties that we may acquire. The amounts and timing of expenditures will depend on the progress of our efforts to expand production at the Velardeña Properties, advance our El Quevar project and continue exploration at these and other properties, the results of consultants' analyses and recommendations, the rate at which operating losses are incurred, the execution of any joint venture agreements with strategic partners, if any, and our potential future acquisition of additional properties, in addition to other factors, many of which will be beyond our control. We expect that the advancement or development of the combined company's properties and any other properties we may acquire will require the commitment of substantial resources. There can be no assurance that the combined company will continue to generate revenues or will ever achieve profitability.

ECU's and Golden's properties may not contain mineral reserves.

None of our El Quevar project, ECU's Velardeña Properties or any of our other properties, has been shown to contain proven or probable mineral reserves. Expenditures made in the exploration and advancement of the properties of the combined company may not result in discoveries of commercially recoverable quantities of ore. Most exploration projects do not result in the discovery of commercially mineable ore deposits and we cannot assure you that any mineral deposit we identify will qualify as an ore body that can be legally and economically exploited or that any particular level of recovery of silver from discovered mineralization will in fact be realized.

Micon has completed technical reports on Golden's El Quevar property, which indicated the presence of "mineralized material," and on ECU's Velardeña Properties, which indicated the presence of measured, indicated and inferred resources. Mineralized material, and measured, indicated and inferred resource figures based on estimates made by geologists are inherently imprecise and depend on geological interpretation and statistical inferences drawn from drilling and sampling that may prove to be unreliable or inaccurate. We cannot assure you that these estimates will be accurate or that proven and probable mineral reserves will be identified at El Quevar, Velardeña or any of Golden's and ECU's other properties. Even if the presence of reserves is established at a project, the economic viability of the project may not justify exploitation. We plan to spend significant amounts on the

Table of Contents

advancement of El Quevar and the expansion of the Velardeña Properties prior to establishing the economic viability of the project in a technical report compliant with NI 43-101.

Estimates of reserves, mineral deposits and production costs can also be affected by such factors as governmental regulations and requirements, fluctuations in metals prices or costs of essential materials or supplies, environmental factors, unforeseen technical difficulties and unusual or unexpected geological formations. In addition, the grade of ore ultimately mined may differ from that indicated by drilling results, sampling, feasibility studies or technical reports. Short term factors relating to reserves, such as the need for orderly development of ore bodies or the processing of new or different grades, may also have an adverse effect on mining operations and on the results of operations. Silver or other minerals recovered in small scale laboratory tests may not be duplicated in large scale tests under on-site production conditions.

We expect that the combined company will continue to require substantial external financing to pay its operating and general and administrative expenses, continue the advancement of the Velardeña expansion and El Quevar projects, and fund its other exploration activities.

We will be required to continue to raise substantial funds from external sources in order to pay our operating and general and administrative expenses, advance the Velardeña expansion and El Quevar projects, maintain our other exploration properties and continue our exploration activities, as we do not expect that cash generated by the Velardeña mining operations will be sufficient to fund these activities. If the Velardeña expansion or the El Quevar project proceeds to development and construction, we anticipate that we would need to raise additional capital during 2011. The size and capital cost for the Velardeña expansion or a possible mine and processing facilities at El Quevar have not been determined and would depend, among other things, on the results of our ongoing efforts to further define the Yaxtché deposit. We do not have a credit agreement in place that would finance development of either the Velardeña expansion or the El Quevar project, and believe that securing credit for these projects may be difficult given our limited history and the continuing volatility in global credit markets. Access to public financing has been negatively impacted by the volatility in the credit markets, which may impact the ability of the combined company to obtain equity or debt financing in the future and, if obtained, to do so on favorable terms. We cannot assure you that we will be able to obtain the necessary financing for the Velardeña expansion or the El Quevar project on favorable terms or at all. Failure to obtain sufficient financing may also result in the delay or indefinite postponement of exploration activities at our other properties.

The existence of secured indebtedness at ECU may limit the flexibility of the combined company to obtain additional financing and pursue certain business opportunities.

Prior to the Transaction, Golden had no indebtedness. At June 30, 2011, ECU had approximately $17.0 million of outstanding term loan indebtedness, bearing interest at an effective rate of 12.8% and requiring 30 monthly principal repayments of $553,951, commencing July 31, 2011 through maturity on December 31, 2013. The term loan is secured by a first mortgage covering substantially all of ECU's assets, including its mining properties and mills. This indebtedness may be prepaid prior to maturity, subject to a prepayment penalty equal to the greater of either the total interest for the immediately preceding three months or 3% of the outstanding term loan principal amount. If such indebtedness had been prepaid on June 30, 2011, the prepayment penalty would have been $498,556. ECU refinanced this indebtedness in early 2011 to extend the maturity on the loan from January 2012 to December 2013.

The presence of secured indebtedness, particularly in a company with limited revenues, has important consequences to the combined company, including (i) making it more difficult to obtain additional financing, (ii) subjecting it to the risk that its assets may be foreclosed upon if it is unable to make required principal and interest payments, (iii) reducing cash flows available for development of

Table of Contents

properties, and (iv) making the combined company more vulnerable than competitors without debt to a downturn in business, the economy or commodity prices. The combined company's ability to service its debt will depend on its operating performance, which is affected by prevailing economic conditions that are outside of its control. If it is unable to support debt service from revenues from ECU's mining operations, the combined company may be forced to divert resources from the development of its other properties, which may have material adverse effects on its growth and future prospects.

The ECU properties could be subject to environmental and other regulatory risks, which the combined company will assume after the Transaction and which could expose the combined company to significant liability and delay, and potentially the suspension or termination of exploration and development efforts.

Mining is subject to federal, state and local environmental regulation in the jurisdictions where the mines are located. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste.

ECU's activities related to the Velardeña Properties are subject to regulation by SEMARNAT, the environmental protection agency of Mexico. Regulations require that an environmental impact statement, known in Mexico as a Manifestación de Impacto Ambiental, be prepared by a third-party contractor for submission to SEMARNAT. Studies required to support the Manifestación de Impacto Ambiental include a detailed analysis of soil, water, vegetation, wildlife, cultural resources and socio-economic impacts. The Manifestación is then published on SEMARNAT's web page and in its official gazette in a national and local newspaper. The Manifestación is discussed at various open hearings, including hearings in the local communities, at which third parties may voice their views. ECU is required to provide proof of local community support of the Manifestación as a condition to final approval. These requirements are applicable to permitting new facilities at ECU's operations and to expansion of ECU's existing facilities.

Environmental legislation is evolving in a manner which will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for companies and their officers, directors and employees. On January 28, 2011, Article 180 of the Mexican Federal General Law of Ecological Balance and Environmental Protection was amended. Among other things, this amendment extends the term during which an individual or entity having a legitimate interest may contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment, natural resources, flora, fauna or human health, making it sufficient to argue that the harm may be caused. Further, the amendment permits the contesting party to challenge a Manifestación de Impacto Ambiental through a variety of administrative or court procedures. As a result of the amendment, more legal actions supported or sponsored by non-governmental groups interested in halting projects may be filed against companies operating in all industrial sectors, including the mining sector. Mexican operations are also subject to the environmental agreements entered into by Mexico, the United States and Canada in connection with the North American Free Trade Agreement. Another initiative that has not yet been enacted, but is being analyzed by the Chamber of Deputies is one related to amendments to the Civil Federal Procedures Code ("CFPC"). This initiative consists of establishing three categories of collective actions, by means of which 30 or more people claiming injury resulting from, among other things, environmental harm, will be deemed to have a sufficient and legitimate interest in seeking, through a civil procedure, restitution, economic compensation or suspension of the activities from which the alleged injury derived. The initiative is expected to be approved by the Chamber of Deputies this year and the related provisions to become effective six months thereafter. If approved, the amendments to the CFPC may result in more litigation with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm.

Future changes in environmental regulation in the jurisdictions where the mines are located may adversely affect the operations of the combined company, make the operations of the combined company prohibitively expensive, or prohibit them altogether. Environmental hazards may exist on the properties in which Golden and ECU currently hold interests, or may hold interests in the future, that are unknown to Golden or ECU at present and that have been caused by Golden, ECU, or previous owners or operators, or that may have occurred naturally. The combined company may be liable for remediating any damage that ECU may have caused. The liability could include response costs for removing or remediating the release and damage to natural resources, including ground water, as well as the payment of fines and penalties.

Insurance fully covering many environmental risks (including potential liability for pollution or other hazards as a result of disposal of waste products occurring from exploration and production) is not generally available. In addition, U.S. or international legislative or regulatory action to address concerns about climate change and greenhouse gas emissions could negatively impact the operations of the combined company.

Title to ECU Properties may be defective or may be challenged.

Under the laws of Mexico, mineral resources belong to the state, and government concessions are required to explore for or exploit mineral reserves. Mineral rights derive from concessions granted, on a discretionary basis, by the Ministry of Economy, pursuant to the Mexican mining law and regulations thereunder. ECU holds title to the Velardeña Properties through these government concessions, but there is no assurance that title to the concessions comprising the Velardeña Properties will not be challenged or impaired following the Transaction. The Velardeña Properties may be subject to prior unregistered agreements, interests or native land claims, and title may be affected by undetected defects. There may be valid challenges to the title of any of the claims comprising the Velardeña Properties that, if successful, could impair development and/or operations with respect to such properties in the future. A defect could result in the combined company losing all or a portion of its right, title, and interest in and to the properties to which the title defect relates.

ECU was previously involved in litigation concerning its ownership of title to four mineral concessions comprising the Santa Juana portion of the Velardeña Properties. In 2009, ECU entered into an agreement to settle the litigation whereby ECU agreed to pay $6.0 million to obtain full title to the concessions. ECU has previously paid $5.0 million of the settlement amount with the remaining $1.0 million installment becoming due in November 2011. Failure to make the remaining payment would result in loss of a 30% interest in the title to the four mining concessions at issue.

Mining concessions in Mexico may be terminated if the obligations of the concessionaire are not satisfied, including obligations to explore or exploit the relevant concession, to pay any relevant fees, to comply with all environmental and safety standards, to provide information to the Ministry of Economy and to allow inspections by the Ministry of Economy. In addition to termination, failure to make timely concession maintenance payments and otherwise comply strictly with applicable laws, regulations and local practices relating to mineral right applications and tenure could result in reduction or expropriation of entitlements.

Mining concessions give exclusive exploration and exploitation rights to the minerals located in the concessions, but do not include surface rights to the real property, such that ECU is required to negotiate the necessary agreements with surface landowners. Many of ECU's mining properties are subject to the Mexican ejido system requiring ECU to contract with the local communities surrounding the properties in order to obtain surface rights to land needed in connection with its mining operations or exploration activities. ECU's contract with the Velardeña Ejido, which provides surface rights to approximately 70% of the Velardeña Properties, expires in December 2011. Negotiations to renew the contract have not yet begun and while ECU expects to be able to obtain a new contract providing the

Table of Contents

same surface rights as the existing contract, no assurances can be made that ECU will be able to do so on favorable terms or at all. The inability to extend these surface rights on favorable terms or otherwise could have a material adverse effect on the operations and financial condition of the combined company.

ECU is actively engaged in mining activities and there are significant hazards involved, not all of which are fully covered by insurance. To the extent the combined company must pay the costs associated with such risks, its business may be negatively affected.

The operation of mines and conduct of exploration programs are subject to numerous risks and hazards, including, but not limited to, environmental hazards, industrial accidents, encountering unusual or unexpected geological formations, formation pressures, cave-ins, fires, power outages, labor disruptions, flooding, seismic activity, rock bursts, accidents relating to historical workings, landslides and periodic interruptions due to inclement or hazardous weather conditions. These occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage, reduced production and delays in mining, asset write-downs, monetary losses and possible legal liability. Although the combined company will maintain insurance against risks inherent in the operation of its business in amounts that it considers to be reasonable, such insurance will contain exclusions and limitations on coverage, the combined company's insurance will not cover all potential risks associated with mining and exploration operations, and related liabilities might exceed policy limits. As a result of any or all of the forgoing, particularly if the facilities are older, the combined company could incur significant liabilities and costs that could adversely affect its results of operation and financial condition.

ECU's mining operations are located in Mexico and are subject to various levels of political, economic, legal and other risks with which Golden has limited or no previous experience.

ECU's operations are conducted in Mexico, and, as such, ECU's operations are exposed to various levels of political, economic, legal and other risks and uncertainties, including military repression; extreme fluctuations in currency exchange rates; high rates of inflation; labor unrest; the risks of war or civil unrest; local acts of violence, including violence from drug cartels; expropriation and nationalization; renegotiation or nullification of existing concessions, licenses, permits and contracts; illegal mining; acts of political corruption; changes in taxation policies; restrictions on foreign exchange and repatriation; and changing political conditions, currency controls and governmental regulations that favor or require the awarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.

In the past, Mexico has been subject to political instability, changes and uncertainties, which have resulted in changes to existing governmental regulations affecting mineral exploration and mining activities. Mexico's status as a developing country may make it more difficult for the combined company to obtain any required financing for the expansion of the Velardeña mines or other projects in Mexico in the future.

ECU's Mexican operations and properties are subject to a variety of governmental regulations governing health and worker safety, employment standards, waste disposal, protection of historic and archaeological sites, mine development, protection of endangered and protected species and other matters. Specifically, ECU's activities related to the Velardeña Properties are subject to regulation by SEMARNAT, the environmental protection agency of Mexico, Comision Nacional del Agua, which regulates water rights, and Mexican mining laws. Mexican regulators have broad authority to shut down and/or levy fines against facilities that do not comply with regulations or standards.

ECU's mineral exploration and mining activities in Mexico may be adversely affected in varying degrees by changing government regulations relating to the mining industry or shifts in political

Table of Contents

conditions that increase the costs related to ECU's Mexican operations or the maintenance of its properties. Changes, if any, in mining or investment policies or shifts in political attitude may adversely affect ECU's operations and financial condition. Operations may be affected in varying degrees by government regulations with respect to restrictions on production, price controls, export controls, currency remittance, income and other taxes, expropriation of property, foreign investment, maintenance of claims, environmental legislation, land use, land claims of local people, water use and mine safety. Expansion of ECU's facilities will also be subject to the need to assure the availability of adequate supplies of water and power, which could be affected by government policy and competing operations in the area.

The occurrence of these various factors and uncertainties cannot be accurately predicted and could have an adverse effect on the combined company's operations and financial condition.

Future changes in applicable laws and regulations or changes in their enforcement or regulatory interpretation could negatively impact current or planned exploration and development activities on the Velardeña Properties or in respect of any other projects in which the combined company becomes involved in Mexico. Any failure to comply with applicable laws and regulations, even if inadvertent, could result in the interruption of exploration and development operations or material fines, penalties or other liabilities.

ECU's employees in Mexico are represented by a collective bargaining unit, and ECU is subject to Mexican regulations regarding labor and employment matters.

ECU's employees in Mexico are represented by a collective bargaining unit, the Sindicato. ECU has two Sindicatos, one for the mine and a second for the plant. The current collective bargaining agreement expired in late June 2011. Salaries are negotiated annually, and labor contracts bi-annually. In addition to the negotiated terms of such agreement, relations between ECU and its employees may be affected by changes in regulations regarding labor relations that may be introduced by the Mexican authorities. Changes in such legislation or in the relationship between ECU and its employees may have a material adverse effect on the combined company's operations and financial condition.

The long-term cash flow and profitability of the combined company will be affected by changes in the prices of silver and other metals.

The ability of the combined company to establish reserves and develop its exploration properties, and its profitability and long-term viability, depend, in large part, on the market prices of silver, zinc, lead, gold, copper and other metals. The market prices for these metals are volatile and are affected by numerous factors beyond our control, including:

•: global or regional consumption patterns;
•: supply of, and demand for, silver, gold, zinc, lead, copper and other metals;
•: speculative activities and producer hedging activities;
•: expectations for inflation;
•: political and economic conditions; and
•: supply of, and demand for, consumables required for production.

Future weakness in the global economy could increase volatility in metals prices or depress metals prices, which could in turn reduce the cash flow generated by the Velardeña Properties, or make it uneconomical for the combined company to continue its mining or exploration activities. Volatility or sustained price declines may also adversely affect the ability of the combined company to build its business.

Results from ECU's Velardeña properties are subject to exchange control policies, the effects of inflation and currency fluctuations between the U.S. Dollar and the Mexican Peso.

ECU's revenues are primarily denominated in U.S. dollars. However, operating costs of ECU's Velardeña Properties are denominated principally in Mexican pesos. These costs principally include electricity, labor, maintenance, local contractors and fuel. Accordingly, when inflation in Mexico increases without a corresponding devaluation of the Mexican peso, ECU's financial position, results of operations and cash flows could be adversely affected. The annual inflation rate in Mexico was 4.4% in 2010, 3.6% in 2009 and 6.5% in 2008. At the same time, the peso has been subject to significant devaluation, which may not have been proportionate to the inflation rate and may not be proportionate to the inflation rate in the future. The value of the peso increased by 5.4% and 3.5% in 2010 and 2009, respectively, and decreased by 24.5% in 2008. In addition, fluctuations in currency exchange rates may have a significant impact on our financial results. There can be no assurance that the Mexican government will maintain its current policies with regard to the peso or that the peso's value will not fluctuate significantly in the future. The imposition of exchange control policies could impair ECU's ability to meet its U.S. dollar-denominated obligations, including payments on its debt. We cannot assure you that currency fluctuations, inflation and exchange control policies will not have an adverse impact on the financial condition, results of operations, earnings and cash flows of the combined company.

If the combined company is unable to obtain all of its required governmental permits or obtain property rights on favorable terms or at all, its operations could be negatively impacted.

Future operations of the combined company, including the new tailings facility at and potential expansion of the Velardeña Properties, the advancement of the El Quevar project, and other exploration and potential development activities, will require additional permits from various governmental authorities. Operations of the combined company are and will continue to be governed by laws and regulations governing prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety, mining royalties and other matters. The combined company may also be required to obtain certain property rights to access or use its properties. Obtaining or renewing licenses and permits, and acquiring property rights, can be complex and time-consuming processes. There can be no assurance that the combined company will be able to acquire all required licenses, permits or property rights on reasonable terms or in a timely manner, or at all, and that such terms will not be adversely changed, that required extensions will be granted, or that the issuance of such licenses, permits or property rights will not be challenged by third parties. Delays in obtaining or a failure to obtain any licenses, permits or property rights or any required extensions; challenges to the issuance of licenses, permits or property rights, whether successful or unsuccessful; changes to the terms of licenses, permits or property rights; or a failure to comply with the terms of any licenses, permits or property rights that have been obtained, could have a material adverse effect on the business of the combined company by delaying or preventing or making continued operations economically unfeasible.

ECU owns its interest in its San Diego property in a 50-50 joint venture and is therefore unable to control all aspects of exploration and development of this property.

ECU holds the San Diego property in a 50-50 joint venture with Golden Tag Resources Ltd. This interest in the San Diego Property is subject to the risks normally associated with the conduct of joint ventures. A disagreement between joint venture partners on how to conduct business efficiently, the inability of joint venture partners to meet their obligations to the joint venture or third parties, or litigation arising between joint venture partners regarding joint venture matters could have a material adverse effect in the viability of ECU's interests held through the joint venture. In 2009, ECU received

Table of Contents

a notice of arbitration from its joint venture partner. The dispute was settled in September 2010, and resulted in an increase in ECU's mining property costs of $61,000.

Risks Related to the Increase in Authorized Capital.

The increase in authorized capital could have anti-takeover effects, and could lead to greater dilution to existing stockholders.

Stockholders are being asked to approve an increase in Golden's authorized capital from 50,000,000 shares to 100,000,000 shares. At the conclusion of the Transaction, Golden will have approximately 12.9 million shares available for issuance. The additional shares will be available for use in acquisitions, future equity financings and for employee equity compensation plans. If the Charter Amendment Proposal is approved, Golden Stockholders will not have the ability in the future to vote on the use of the shares, except in limited instances mandated by stock exchange rules. Accordingly, the directors would be able to issue shares in financings or acquisitions at prices that may not reflect market prices, or are otherwise dilutive to stockholders. In addition, the availability of a number of authorized and unissued shares could have anti-takeover effects and could be used by incumbent management to perpetuate its positions, even in the face of an acquisition that is regarded as beneficial by stockholders. For example, shares could be placed with a stockholder that is supportive of existing management, diluting the ownership of a hostile acquirer. There can be no assurance that the shares will be issued in a manner that is advantageous to existing stockholders.

GENERAL INFORMATION CONCERNING THE GOLDEN MEETING

The enclosed proxy is solicited on behalf of Golden's board of directors for use at a special meeting of Golden's stockholders to be held on August 30, 2011, at 9:00 a.m., Denver time, or at any adjournments, postponements or delays thereof, for the purposes set forth in this proxy statement and in the accompanying notice of special meeting. The special meeting will be held at Courtyard by Marriott Denver West/Golden, 14700 W. 6th Avenue Frontage Road, Golden, Colorado 80401. Golden intends to commence mailing of this proxy statement and the accompanying proxy card to Golden's stockholders on or about August 2, 2011.

At the special meeting, Golden's stockholders will be asked to vote on:

•: Share Issuance Proposal—the issuance of shares of Golden common stock (including shares issuable upon exercise of Golden Replacement Options and Golden Replacement Warrants) in connection with the Transaction; and
•: Charter Amendment Proposal—an amendment to Golden's certificate of incorporation to increase the authorized number of shares of Golden common stock from 50,000,000 to 100,000,000.

Golden does not expect a vote to be taken on any other matters at the special meeting. If any other matters are properly presented at the special meeting for consideration, however, the holders of the proxies will have discretion to vote on these matters in accordance with their best judgment.

Golden's board of directors has unanimously approved the Transaction and the issuance of Golden common stock in connection with the Transaction. In addition, our board has determined that an increase in the authorized number of shares of Golden common stock is advisable in order to provide the Golden board additional capacity to issue shares in the future, including for future offerings or acquisitions as determined to be in the best interests of the Golden stockholders. Accordingly, the board of directors unanimously recommends that Golden's stockholders vote "FOR" the Share Issuance Proposal and "FOR" the Charter Amendment Proposal.

Only approval of the Share Issuance Proposal is required to effect the Transaction. If the Charter Amendment Proposal is approved but the Share Issuance Proposal is not approved, Golden will not amend its certificate of incorporation to increase the authorized number of shares of Golden common stock. Golden stockholders will cast separate votes on each proposal.

There are certain risks associated with the Transaction, which are described under the heading "Risk Factors," beginning on page 14.

Record Date and Voting Information

Only holders of record of Golden common stock at the close of business on July 29, 2011 are entitled to notice of and to vote at the special meeting. At the close of business on July 29, 2011, 15,019,770 shares of Golden common stock were outstanding and entitled to vote. A list of Golden's stockholders will be available for review at Golden's executive offices during regular business hours after the date of this proxy statement and through the date of the special meeting. Each holder of record of Golden common stock on the record date will be entitled to one vote for each share held. The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Golden common stock entitled to vote at the special meeting is necessary to constitute a quorum for the transaction of business at the special meeting.

All votes will be tabulated by the inspector of election appointed for the special meeting, who will separately tabulate votes "FOR" and "AGAINST," abstentions and broker non-votes. If a stockholder's shares are held of record by a broker, bank or other nominee and the stockholder wishes to vote at the special meeting, the stockholder must obtain from the record holder a "legal" proxy issued in the

Table of Contents

stockholder's name. Brokers who hold shares in "street name" for clients typically have the authority to vote on "routine" proposals when they have not received instructions from beneficial owners. Absent specific instructions from the beneficial owner of the shares, brokers are not allowed to exercise their voting discretion with respect to the approval of "non-routine" matters, such as the Share Issuance Proposal. Broker non-votes are counted for purposes of determining whether a quorum exists at the special meeting.

Proxies received at any time before the special meeting and not revoked or superseded before being voted will be voted at the special meeting. If the proxy indicates a specification, it will be voted in accordance with the specification. If no specification is indicated, the proxy will be voted "FOR" the Share Issuance Proposal and "FOR" the Charter Amendment Proposal, and in the discretion of the persons named in the proxy with respect to any other business that may properly come before the special meeting or any adjournment of the special meeting. You may also vote in person by ballot at the special meeting.

Required Vote of Golden's Stockholders

The Share Issuance Proposal must be approved by the affirmative vote of a majority of the shares of Golden common stock present at the special meeting and entitled to vote, assuming a quorum is present. The Charter Amendment Proposal must be approved by the affirmative vote of a majority of the outstanding shares of Golden common stock. Abstentions will have the same effect as a vote "AGAINST" the Share Issuance Proposal and the Charter Amendment Proposal. Shares held through brokers may be voted by the brokers on the Charter Amendment Proposal but not the Share Issuance Proposal. A broker's failure to vote on the Share Issuance Proposal because it lacks discretionary authority to do so, commonly referred to as a "broker non-vote," will not affect the outcome of the vote on the Share Issuance Proposal.

Golden's Board Recommendation

Golden's board of directors unanimously recommends that Golden's stockholders vote "FOR" the Share Issuance Proposal and "FOR" the Charter Amendment Proposal.

Opinion of Golden's Financial Advisor

On June 23, 2011 Golden's board of directors received an opinion from BMO Capital Markets Corp. to the effect that, as of June 23, 2011, and based upon and subject to the factors, assumptions, qualifications and limitations set forth in such opinion, the exchange ratio, together with the cash consideration to be paid by Golden pursuant to the Transaction, was fair, from a financial point of view, to Golden.

How You Can Vote

•: giving written notice of revocation to Golden's Corporate Secretary;
•: submitting another proper proxy via the Internet, by telephone, or a later-dated written proxy; or
•: attending the special meeting and voting by paper ballot in person. Your attendance at the special meeting alone will not revoke your proxy.

If you hold your Golden common stock in "street name," you should contact your bank, brokerage firm or other nominee for instructions regarding how to change your vote. You may also vote in person at the special meeting if you obtain a "legal" proxy from your bank, brokerage firm or other nominee.

Shares Beneficially Owned by Golden Directors and Executive Officers

On the record date, Golden directors and named executive officers beneficially owned and had the right to vote approximately 271,661 Golden shares. These shares represent, in the aggregate, approximately 1.8% of the total voting power of Golden's outstanding common stock entitled to vote at the special meeting. During July 2011, ECU entered into a voting agreement with each of Golden's executive officers and expects to enter into such agreements with each of Golden's directors prior to the meeting date. Pursuant to these voting agreements, the Golden directors and officers party to such agreements committed to vote their shares of Golden common stock in support of the Transaction. See "The Transaction—Voting Agreements" beginning on page 43 for a further description of the voting agreements.

Expenses of Proxy Solicitation

THE TRANSACTION

General

On June 24, 2011, Golden and ECU entered into the Arrangement Agreement, which sets forth the terms under which Golden will acquire all of the ECU Shares, ECU Options and ECU Warrants in accordance with the Plan of Arrangement to be submitted for approval by the Québec Court. Pursuant to the Arrangement Agreement, Golden will acquire all the ECU Shares pursuant to the Plan of Arrangement in exchange for Golden common stock and cash.

The Arrangement Agreement and Plan of Arrangement provide that ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each ECU common share held immediately prior to the consummation of the Transaction. In addition, upon the consummation of the Transaction, new Golden options to purchase Golden common stock, or "Golden Replacement Options," will be exchanged for all outstanding options to purchase ECU common shares, and new Golden warrants to purchase Golden common stock, or "Golden Replacement Warrants," will be exchanged for all outstanding warrants to purchase ECU common shares. It is anticipated that consummation of the Transaction pursuant to the Plan of Arrangement will result in Golden paying an aggregate of approximately Cdn$125,000 in cash and issuing a total of approximately 16.0 million new shares, not including up to approximately 2.9 million new shares that will be issuable following the exercise of currently outstanding ECU options and warrants (or upon the exercise of the Golden Replacement Options and Golden Replacement Warrants to be received in exchange for those options and warrants) and approximately 167,000 shares that are expected to be issued, in the aggregate, in satisfaction of certain ECU change of control payments.

Background of the Transaction

Golden's management and board of directors routinely monitor and assess developments in the mining and exploration industries and regularly consider growth opportunities, including the acquisition of operating mines, exploration properties and businesses.

On January 11, 2011, Mr. Jeffrey G. Clevenger, Chairman, President and Chief Executive Officer of Golden, and Jerry Danni, Executive Vice President of Golden, met in New York with representatives of Dahlman Rose & Company, an investment banking firm which specializes in the mining industry. Among other issues related to industry developments and strategic considerations, the representatives of Dahlman Rose stated that they had been engaged by ECU to pursue strategic alternatives and discussed with Mr. Clevenger and Mr. Danni the possibility of a strategic investment in or combination with ECU. Following this meeting, representatives of Dahlman Rose provided Mr. Clevenger and Mr. Danni with certain publicly available information regarding ECU. Representatives of Dahlman Rose conducted another informal discussion regarding ECU with Mr. Danni on March 8, 2011, at the Prospectors and Developers Association of Canada annual conference in Toronto.

In late March 2011, Golden management commenced a review, based on public information, of several potential acquisition targets and strategic business combination partners, including ECU. The preliminary analysis of ECU was completed during the first week of April 2011. On April 4, 2011, Mr. Clevenger asked a representative of Dahlman Rose to arrange an introductory meeting with appropriate ECU executives.

On April 13, 2011, Mr. Clevenger and Mr. Danni met with Stephen Altmann, President of ECU, and representatives of Dahlman Rose in Zurich, Switzerland, where they were attending the annual meeting of the European Gold Forum. At this meeting, Messrs. Clevenger, Danni and Altmann provided general overviews of their companies based solely on publicly available information. They discussed the possibility of a strategic business combination and whether each party was interested in pursuing further discussions. Messrs. Clevenger, Danni and Altmann concluded the meeting with an

Table of Contents

agreement to continue preliminary discussions and to enter into a confidentiality agreement in respect of the planned discussions.

Golden management and ECU management then negotiated a mutual confidentiality agreement, which was executed on April 21, 2011. The confidentiality agreement included a two year "standstill" agreement under which each of Golden and ECU agreed not to propose a takeover or business combination transaction to the other or its stockholders without the consent of the other's board of directors. During this period, Mr. Clevenger and Mr. Altmann spoke by telephone and communicated by email regarding the coordination of initial due diligence activities, including travel to ECU's Velardeña District properties in Mexico and Golden's El Quevar advanced exploration project in Argentina.

On April 27, 28 and 29, 2011, David Drips, Golden's Project Director, Argentina, and Mr. Robert Blakestad, Golden's Senior Vice President and Chief Geologist, conducted on-site due diligence at ECU's Velardeña District mines, processing facilities and properties and received information regarding mining, processing, geology, ore controls, exploration and potential areas for additional discovery.

On May 2, 2011, ECU provided Golden with preliminary technical data and corporate information.

On May 9 and 10, 2011, Mr. Clevenger had discussions by telephone with representatives of BMO Capital Markets regarding its acting as Golden's financial advisors and requested BMO Capital Markets to serve as its financial advisor in connection with a potential business combination transaction with ECU.

On May 10, 11 and 12, 2011, Messrs. Clevenger and Drips conducted additional on-site due diligence of the Velardeña mines, properties and processing facilities. In addition, on May 11, 2011, Mr. Clevenger, Mr. Altmann and Mr. Michel Roy, Chairman and Chief Executive Officer of ECU, discussed their views regarding the potential strategic and financial benefits of a business combination transaction between Golden and ECU. They agreed that a combined company would be stronger and better capitalized, and would have better access to capital markets as a result of increased size and the combination of current silver and other metals production in Mexico, the El Quevar advanced exploration project in Argentina, advanced exploration projects in Mexico and Peru, and a pipeline of advanced and reconnaissance exploration projects. They agreed that ECU's producing operations in Mexico would benefit from the operations expertise and experience of Golden's management, and that Golden's exploration efforts would benefit from the participation of ECU management. They also discussed the roles their respective management teams might have in the combined company, including the likelihood that Mr. Roy would serve as a consultant to the combined entity, and the potential for one of ECU's directors to serve on the board of directors of the combined company. They agreed that a business combination between the two companies was a mutually desirable prospect as an at-market merger of equals, although no specific exchange ratio was discussed at that time. They also discussed the possibility of Golden providing financing to ECU pending completion of an agreed business combination transaction. They agreed that Mr. Roy and members of his management would conduct a due diligence trip to Golden's El Quevar project during the week of May 23. They further agreed that it would be desirable for the two companies to enter into an exclusivity agreement, pursuant to which they would agree to continue discussions and negotiations regarding a business combination, and not to hold such discussions with other parties, until June 30, 2011.

During the week of May 9, Golden engaged Davis Graham & Stubbs, LLP ("Davis Graham") and Fasken Martineau DuMoulin LLP ("Fasken Martineau") as its respective U.S. and Canadian legal advisors to assist in the potential transaction. During this week, Golden's legal and financial advisors began conducting their preliminary due diligence review of ECU's publicly available materials and preparing an exclusivity agreement and nonbinding proposal setting forth certain terms of a potential business combination.

Table of Contents

On May 13, 2011, Mr. Clevenger provided the Golden board of directors with a written report regarding ECU and its business, together with the status of the due diligence investigation and discussions with ECU about a potential transaction.

On May 19, 2011, the Golden board of directors held a regularly scheduled meeting in Golden, Colorado. At the meeting, Golden management presented the results of its technical due diligence investigation and Mr. Clevenger updated the board on the status of discussions with ECU regarding a potential strategic combination. At the same meeting, BMO Capital Markets presented to the Board its preliminary transaction perspectives, based on public information. The technical and legal due diligence process, regulatory filings and requirements, and an anticipated timeline were also discussed. After discussion, the Golden board of directors authorized members of Golden management to continue negotiations with ECU, including negotiation and execution of a nonbinding expression of interest and a binding exclusivity agreement.

At Mr. Clevenger's invitation, a representative of The Sentient Group attended the May 19, 2011, Board meeting by telephone. Funds managed by affiliates of The Sentient Group own approximately 19.2 percent of Golden outstanding stock, and The Sentient Group and its representative have entered into a confidentiality agreement with Golden. At the Board meeting, the Sentient Group representative indicated its preliminary support for the potential transaction and asked to visit ECU's properties.

On May 20, 2011, Mr. Clevenger delivered to Mr. Roy and Mr. Altmann drafts of a non-binding preliminary expression of interest, and a binding exclusivity agreement. During the week of May 23, 2011, the parties and their legal and financial advisors discussed the structure of a potential transaction and negotiated the terms of the non-binding expression of interest and exclusivity agreement.

Also during the week of May 23, 2011, Mr. Roy and representatives of ECU's management conducted technical due diligence at Golden's El Quevar project in Argentina.

On May 26, 2011, the Golden board of directors held a special meeting by telephone to consider the terms of the non-binding preliminary expression of interest and binding exclusivity agreement. At the meeting, Mr. Clevenger, Davis Graham and BMO Capital Markets briefed the board regarding the status of discussions with ECU and the proposed terms of the expression of interest and exclusivity agreement. After discussion, the board of directors unanimously authorized Golden management to continue negotiations with ECU, to present to ECU the negotiated non-binding preliminary expression of interest, to enter into the exclusivity agreement, to proceed with additional technical and legal due diligence and to present to ECU a draft business combination agreement.

Following the board meeting, Mr. Clevenger and Mr. Altmann negotiated the final terms of the expression of interest and exclusivity agreement. On May 31, 2011, Golden submitted the non-binding preliminary expression of interest to ECU regarding a "merger of equals" transaction, which ECU countersigned. The expression of interest did not provide for an agreed-upon exchange ratio. The parties also entered into the exclusivity agreement pursuant to which the parties agreed not to pursue a business combination transaction with any other party until June 30, 2011.

During the week of June 6, 2011, ECU and Golden each provided the other and their respective legal and financial advisors with access to an electronic data room containing non-public information responsive to the due diligence requests each had previously submitted to the other. Golden, ECU and their respective legal and financial advisors conducted due diligence reviews of materials provided until and including the date definitive transaction agreements were signed.

In addition, Golden and its advisors continued to conduct additional on-site due diligence on ECU's properties. On June 2, 2011, Mr. Danni and a technical consultant expert in tailings dam construction, design and performance reviewed matters at ECU's properties related to the capacity of existing tailings facilities and the status of plans and permitting for a new tailings facility. Mr. Drips also visited ECU properties from May 31 to June 4, 2011. From June 7 through June 9, 2011,

On June 13, 2011, trading volume of ECU's common shares was approximately 3.4 million shares and the share price closed approximately 18% over the June 10, 2011 closing share price. The Toronto Stock Exchange contacted Mr. Altmann on June 13, 2011, regarding the increased trading activity and, in response to questions, Mr. Altmann and a representative of Blake Cassels & Graydon LLP, Canadian legal counsel to ECU, reported that ECU was conducting discussions with Golden regarding a potential business combination transaction, but that no definitive agreements had been entered into and no exchange ratio had been agreed.

On June 13, 2011, Fasken Martineau sent a draft of the Arrangement Agreement to Blake, Cassels & Graydon LLP and Skadden, Arps, Slate, Meagher & Flom LLP, U.S. legal counsel to ECU. From then until June 24, 2011, the parties and their legal counsel negotiated the terms of the Arrangement Agreement and related documents, including a term sheet for a convertible debt financing contemplated to be provided by Golden to ECU, and exchanged drafts of the Arrangement Agreement and related documents. During this period, Mr. Clevenger also discussed with Mr. Altmann and with members of the compensation committee of Golden's board of directors the terms on which Mr. Altmann would serve as president of the combined company, if a strategic combination were completed.

On June 22, 2011, Messrs. Roy and Clevenger met in Denver, Colorado and discussed certain issues related to strategic plans for the combined company.

On June 22, 2011, the Golden board of directors held a special meeting by telephone which was also attended by Golden management and representatives of BMO Capital Markets, Davis Graham and Fasken Martineau. Davis Graham briefed the Board on the legal standards applicable in the context of evaluating a business combination of the type being considered. In the course of the meeting, members of Golden management and representatives of Davis Graham provided a final report on the due diligence investigation conducted and management's corresponding assessments. The diligence summary included a discussion of ECU's operations and plans, mineral qualities and processes, environmental matters, community relations, and other financial and legal matters. Representatives of Davis Graham and Fasken Martineau also provided an overview of the key terms of the proposed Arrangement Agreement, including termination rights and break-up fees under the Arrangement Agreement. The Golden board of directors then met in executive session to further discuss the information presented, including certain items that remained to be agreed by Golden including the exchange ratio, the amount of the break-up fee, the amount of expense reimbursement to be paid in the event of termination not resulting in a break-up fee and certain issues related to the interim financing. The board received the advice of its financial and legal advisors regarding these matters, authorized management to conclude the negotiation and scheduled a further meeting for the following day.

At Mr. Clevenger's invitation, a representative of The Sentient Group attended the June 22, 2011, Board meeting by telephone. At the Board meeting, the Sentient Group representative reiterated Sentient's support for the transaction and indicated that in the event the transaction was consummated, Sentient would be interested in investing further capital in the combined company to retain its current proportionate ownership.

Over the evening of June 22 and through June 23, 2011, Mr. Clevenger and Mr. Altmann negotiated the final terms of the Arrangement Agreement, including the 0.05 exchange ratio, and Golden and ECU and their respective legal counsel and financial advisors worked to finalize the Arrangement Agreement, the terms of the related financing to be provided to ECU by Golden and related agreements. Following negotiations among the management and financial and legal representatives of Golden and ECU, the Golden board of directors held a special telephonic meeting on June 23, 2011, with members of Golden's management and legal and financial advisors. The Board received an update on resolution of the matters discussed the previous day and discussed the terms of the Arrangement Agreement and related financing. Representatives of BMO Capital Markets then presented to the board its final financial analysis of the proposed business combination and rendered to the Golden board an oral opinion (subsequently confirmed by delivery of a written opinion dated as of June 23, 2011) to the effect that, as of that date and based upon and subject to the factors, assumptions, qualifications and limitations to be set forth in such opinion, the 0.05 exchange ratio and cash consideration provided for in the Arrangement Agreement was fair, from a financial point of view, to Golden. Following discussion with its financial and legal advisors, the Golden board unanimously authorized execution of the Arrangement Agreement and related documents and recommended the issuance of Golden common stock pursuant to the Arrangement Agreement for approval by Golden's stockholders.

With all remaining transaction issues having been settled during the night of June 23, 2011, the ECU board of directors on June 24, 2011 unanimously approved the proposed Transaction and the private placement.

On June 24, 2011, members of Golden senior management and ECU senior management executed the Arrangement Agreement and a subscription agreement for the private placement described below, and issued a joint press release announcing the Transaction.

Subscription Agreement and Private Placement

On July 13, 2011, ECU completed a private placement of Cdn$15.0 million, 0.0% senior unsecured convertible notes at par (the "Convertible Notes") to Golden pursuant to a subscription agreement (the "Subscription Agreement") between the parties dated June 24, 2011 (the "Private Placement"). Golden did not own or exercise control over any securities of ECU prior to the Private Placement. The Convertible Notes will mature on June 30, 2012 (subject to extension as described below), and are convertible by Golden at any time prior to 5:00 p.m. (Toronto time) on June 29, 2012, into common shares of ECU at the rate of 1,032 shares per $1,000 principal amount, consistent with the exchange ratio. As of July 13, 2011, the shares issuable upon conversion of the Convertible Notes represented approximately 4.7% of the outstanding common shares of ECU on an as-converted basis. The Convertible Notes are also redeemable at par by ECU at any time after the record date for voting upon the Transaction at the ECU securityholder meeting. In addition, ECU may elect to extend the maturity of the Convertible Notes for 6 months under certain conditions and upon a cash payment equal to 4% of the outstanding principal amount of the Convertible Notes, with interest accruing at 10% per annum during such extension period. The proceeds of the Private Placement were placed into escrow and are to be advanced to ECU pursuant to specific disbursement requests to be submitted to Golden and the escrow agent identifying the intended use of such funds. The Private Placement proceeds are to be used by ECU for general corporate purposes and to fund its ongoing expansion plans at the Velardeña Properties until closing of the Transaction.

Table of Contents

Golden, as holder of the Convertible Notes, is entitled to vote any ECU common shares received upon conversion of the Convertible Notes before the record date for voting upon the Transaction at the ECU securityholder meeting or may vote the Notes themselves in any vote of ECU's outstanding common shares, options, warrants and convertible securities voting as a single class with respect to the votes of ECU Securityholders to approve the Transaction.

Golden's Reasons for the Transaction; Recommendation of Golden's Board of Directors

On June 24, 2011, following completion of due diligence, Golden's board of directors, after an extensive review and thorough discussion of all facts and issues it considered relevant with respect to the proposed transactions, concluded unanimously that the Transaction and Private Placement are fair to, and in the best interests of, the Golden stockholders, and authorized Golden's executive officers to enter into the Arrangement Agreement, Subscription Agreement and related agreements and recommend to Golden stockholders that they vote in favor of the Share Issuance Proposal.

In reaching its conclusion and making its recommendation, the members of Golden's board of directors consulted with Golden management, as well as its financial and legal advisors, and considered various other factors, both positive and negative. The following discussion of the information and factors considered by Golden's board of directors is not intended to be exhaustive and may not include all of the factors considered by the board. In view of the wide variety of factors considered by the Golden board in connection with its evaluation of the Transaction, the Golden board did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. In considering the factors described below, individual members of the Golden board may have given different weight to different factors. The Golden board considered this information as a whole and considered overall the information and factors to be favorable to, and in support of, its determinations and recommendations. The material information and factors considered by the Golden board included the following:

Strategic Considerations.—Golden's board of directors considered a number of factors pertaining to the strategic rationale for the Transaction, including the following:

•: Portfolio Growth—The Transaction will provide Golden, through ECU's Velardeña project, with exposure to ECU's position in one of Mexico's most prolific silver belts, and access to a producing mine with significant potential growth prospects.
•: Value Creation—The Transaction is expected to allow Golden to leverage its existing excess cash position by supporting the further development and expansion of exploration and production at ECU's Velardeña Properties.
•: Unification of Complementary Management—Golden and ECU have complementary management teams with proven successful track records that are expected to allow the combined company to optimize existing development plans and mining operations. Upon completion of the Transaction, management will have a significant depth of experience in exploration, resource conversion, project development, and mining of both open pit and underground operations.
•: Geographic Diversification—The Transaction increases asset and geographic diversification benefits for Golden with production in Mexico and advanced exploration properties in Argentina, Mexico and Peru.
•: Increased Scale—The Transaction will create a combined company with greater scale, financial strength and an enhanced capital markets profile, with available funds to continue to advance expansion plans at Velardeña and the exploration of El Quevar. The Transaction will also provide Golden with exposure to new investors and is expected to improve the company's access to global capital markets to assist future growth objectives.

Table of Contents

•: Increased Portfolio of Silver Assets—The Transaction continues the strategy that Golden is currently pursuing of building a portfolio of quality silver producing assets in low political risk jurisdictions.

Fairness Opinion—The fairness opinion provided by BMO Capital Markets on June 23, 2011, subsequently confirmed in writing, to the effect that, as of June 23, 2011, and based upon and subject to the analyses, factors, assumptions, qualifications and limitations set forth in such opinion, the exchange ratio and cash consideration was fair, from a financial point of view, to Golden.

Recommendation of Management—The recommendation of Golden management in support of the Transaction.

Stockholder Support—Sentient's expression of its support of the Transaction as one of Golden's largest stockholders, and Sentient's indication of its potential interest in investing additional capital in Golden following consummation of the Transaction in order to maintain its proportionate ownership interest in Golden.

Due Diligence—The results of the due diligence review conducted by Golden's management and Golden's financial and legal advisors, including the information included in the disclosure letter delivered by ECU to Golden in connection with the Arrangement Agreement. The Golden board also considered the scope of the representations and warranties in the Arrangement Agreement in light of the matters raised in the course of the due diligence review.

Ability to Accept a Superior Proposal—The fact that, under the terms of the Arrangement Agreement, the Golden board of directors remains able to respond in accordance with its fiduciary duties in the event of certain unsolicited proposals that are more favorable to Golden stockholders than the Transaction, and the fact that the ECU board has the same rights under the agreement.

Golden Stockholder Approval—The fact that the issuance of Golden common stock to ECU shareholders pursuant to the Transaction must be approved by no less than a majority of the Golden common stock present at the special meeting and entitled to vote thereon. The Golden board of directors believes that the required stockholder approval protects the rights of Golden stockholders.

Market and Industry Trends—Current economic, industry and market trends affecting Golden and ECU and the current and historical trading prices of their respective common stock.

Consideration—The amount and type of consideration to be paid and issued pursuant to the Transaction and the fact that the Exchange Ratio is fixed to reflect an at-market combination at the time of negotiations and will not fluctuate based upon changes in the market price of Golden or ECU common stock between the date of the Arrangement Agreement and the date of the completion of the Transaction.

Dilution of Golden Stockholders' Ownership Interest in the Combined Company—The fact that as a result of the issuance of Golden shares in the Transaction, Golden's existing stockholders will experience a significant degree of dilution in their ownership of Golden to approximately 49% of the combined company (or approximately 45% if all ECU options and warrants were exercised) while former shareholders of ECU will own approximately 51% of the combined company (or approximately 55% on a fully-diluted basis). Additionally, due to the fact that Golden's existing stockholders would hold less than 50% of the company following the Transaction, the board considered that the vesting of certain equity awards made to Golden's directors and officers would accelerate upon consummation of the Transaction, as it would be deemed a change of control of the company pursuant to the governing award agreements, and that certain severance payments may subsequently become payable to Golden executive officers upon the termination of their employment.

Table of Contents

Restrictions on Business Operations—The fact that Golden and ECU would agree to restrictions on the conduct of each other's business during the period between the execution of the Arrangement Agreement and the completion of the Transaction.

Termination Fee and Expense Reimbursement—The fact that Golden and ECU may be obligated to pay a termination fee or reimburse the other party's transaction expenses under the Arrangement Agreement in certain circumstances.

No-Shop Provision—The fact that Golden and ECU would each agree to a "no-shop" clause pursuant to the Arrangement Agreement restricting each party's ability to solicit a competing transaction.

Dissenters' Rights—The availability of dissenters' rights to the ECU shareholders in connection with the Transaction and the existence of a condition to closing which permits Golden to not close the Transaction if more than 5% of ECU shareholders exercise their dissenters' rights.

The members of Golden's board of directors also considered potential risks associated with the Transaction, including among other things, the following:

Inherent Uncertainty of Estimates—The fact that there was inherent uncertainty regarding the estimated value of the Velardeña Properties and the estimates of the future development costs that would need to be incurred with respect to the Velardeña Properties and about the quality, quantity and recoverability of any ore body at the Velardeña Properties.

Business Risks—The risks associated with and inherent in ECU's business and its operations in Mexico, including the nature and potential scope of items identified pursuant to Golden's managements' and outside advisors' due diligence review and the inherent limitations of such processes.

Market Disruption if Transaction Not Completed—The fact that if the Transaction is not completed, Golden may be adversely affected due to potential disruptions in its operations and market perceptions.

Diversion of Management—The possible diversion of management's time and attention from the ongoing business of Golden due to the substantial time and effort necessary to complete the Transaction and plan for and implement the integration of the operations of Golden and ECU.

Integration Challenges—The challenges inherent in the combination of two enterprises of the size and scope of Golden and ECU, and the risk that anticipated benefits, long-term as well as short-term, of the Transaction for Golden stockholders might not be realized.

After consideration of these material factors, the Golden board concluded that the risks associated with the Transaction could be (i) mitigated or managed by Golden or, following the Transaction, by the combined company, (ii) were reasonably acceptable under the circumstances, and (iii) in light of the anticipated benefits overall, were significantly outweighed by the potential benefits of the Transaction. The Golden board realized that there can be no assurance about future results, including results considered or expected as described in the factors listed above, such as assumptions regarding the potential benefits of the Transaction. It should be noted that this explanation of the Golden board's reasoning and all other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading "Cautionary Statements Regarding Forward-Looking Information" beginning on page 1.

Fairness Opinion of Financial Advisor to Golden

Golden retained BMO Capital Markets Corp. to render an opinion to the Golden board of directors as to the fairness, from a financial point of view, to Golden of the exchange ratio of 0.05 of a share of Golden common stock (which is referred to as the exchange ratio) and Cdn$0.000394 in cash,

Table of Contents

to be paid for each outstanding share of ECU stock in connection with the Transaction. On June 23, 2011, at a meeting of Golden's board of directors held to evaluate the Transaction, BMO Capital Markets delivered its oral opinion, which opinion was subsequently confirmed by delivery of its written opinion dated June 23, 2011, to the effect that, as of that date and subject to the various factors, assumptions, qualifications and limitations set forth in such opinion, the exchange ratio, together with the cash consideration payable in the Transaction, was fair, from a financial point of view, to Golden. BMO Capital Markets does not have any obligation to update, revise or reaffirm its opinion.

The full text of BMO Capital Markets' written opinion to Golden board of directors, which sets forth, among other things, the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached as Annex F to this proxy statement and is incorporated into this proxy statement by reference. Holders of Golden common stock are encouraged to read the opinion carefully and in its entirety. The following summary is qualified in its entirety by reference to the full text of such opinion. BMO Capital Markets' analyses and opinion were prepared for and addressed to the Golden board of directors and relate only to the fairness, from a financial point of view, to Golden of the exchange ratio and the cash consideration payable in the Transaction. BMO Capital Markets' opinion does not address any other aspect of the Transaction or the transactions contemplated by the Arrangement Agreement and such opinion does not constitute a recommendation to Golden Stockholders or anyone else on how to vote at any meeting held in connection with the Transaction. BMO Capital Markets' opinion also does not in any manner address the prices at which Golden or ECU common stock has traded or may trade in the future, including subsequent to the completion of the Transaction. The BMO Capital Markets opinion has been approved by a fairness committee of BMO Capital Markets.

BMO Capital Markets provided the opinion described herein for the information and assistance of Golden's board of directors in connection with its consideration of the transactions contemplated by the Arrangement Agreement and Plan of Arrangement. The terms of the Arrangement Agreement and the Plan of Arrangement, and the Exchange Ratio and cash consideration payable, were determined through negotiations between Golden and ECU, and were approved by Golden's board of directors. BMO Capital Markets provided financial advice to Golden during such negotiations. However, BMO Capital Markets did not recommend any form of consideration to Golden or that any specific form of consideration constituted the only appropriate consideration for the Transaction.

In preparing its opinion to the Golden board of directors, BMO Capital Markets performed various financial and comparative analyses, including those described below. The summary set forth below does not purport to be a complete description of the analyses underlying BMO Capital Markets' opinion or the presentation made by BMO Capital Markets to the Golden board of directors. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, BMO Capital Markets did not attribute any particular weight to any analysis or factor considered by it, but rather made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. Each of the analyses conducted by BMO Capital Markets was carried out in order to provide a different perspective on the financial terms of the Transaction and add to the total mix of information available. The analyses were prepared solely for the purpose of BMO Capital Markets providing its opinion and do not purport to be appraisals or necessarily reflect prices at which securities may be sold. BMO Capital Markets did not form a conclusion as to whether any individual analysis, considered in isolation, supported or failed to support an opinion about the fairness, from a financial point of view, to Golden of the exchange ratio and cash consideration payable. Rather, in reaching its conclusion, BMO Capital Markets considered the results of the analyses in light of each other and ultimately reached its opinion based on the results of the analyses taken as a whole. Accordingly,

notwithstanding the separate analyses summarized below, BMO Capital Markets believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors, or focusing on information presented in tabular format, without considering all of the analyses and factors or the narrative description of the analyses, would create a misleading or incomplete view of the process underlying its opinion.

In arriving at its opinion, and performing the related financial analysis, BMO Capital Markets:

•: reviewed the June 23, 2011 draft of the Arrangement Agreement and Plan of Arrangement;
•: reviewed a draft copy of the Subscription Agreement between Golden and ECU;
•: reviewed internal management forecasts prepared by or on behalf of Golden and ECU;
•: reviewed operating and financial forecasts for Golden provided by the management of Golden and operating and financial forecasts for ECU provided by ECU's management and adjusted by management of Golden;
•: reviewed certain other internal information prepared by or on behalf of Golden;
•: reviewed public information (including that prepared by industry research analysts) relating to the business, operations, and financial condition and trading history of Golden, ECU, and other selected public issuers BMO Capital Markets considered relevant;
•: reviewed letters of representation as to certain factual matters and the completeness and accuracy of the information upon which the opinion is based provided by senior officers of Golden;
•: reviewed such other information, investigations, analyses and discussions as BMO Capital Markets considered necessary or appropriate in the circumstances;
•: conducted discussions with members of senior management and representatives of Golden concerning the respective operations, financial condition and prospects of Golden and ECU;
•: reviewed relevant financial contributions from both Golden and ECU to the combined entity resulting from the Transaction;
•: reviewed the pro forma impact of the Transaction on Golden, based on assumptions relating to transaction expenses, and purchase accounting assumptions determined by senior management of Golden;
•: reviewed historical stock prices of the common stock of Golden and ECU; and
•: reviewed such other financial studies and performed such other analyses and investigations and took into account such other matters as were deemed appropriate.

In rendering its opinion, BMO Capital Markets assumed and relied on the accuracy and completeness of information supplied or otherwise made available to BMO Capital Markets by Golden, ECU or their representatives or advisors or obtained by BMO Capital Markets from other sources. BMO Capital Markets did not assume any responsibility for independently verifying and did not independently verify such information. BMO Capital Markets did not independently evaluate, physically inspect or appraise any of the respective assets or liabilities (contingent or otherwise) of Golden or ECU and was not furnished with any such valuations or appraisals. BMO Capital Markets was not asked to and did not evaluate the solvency or fair value of Golden or ECU. With respect to financial projections, including estimated synergies, for Golden and ECU, BMO Capital Markets was advised by Golden, and assumed, without independent investigation, that they had been reasonably prepared and reflected the best currently available estimates and good faith judgments of senior management of Golden and ECU (or, with respect to estimates and forecasts obtained from public sources, represent

Table of Contents

reasonable estimates and forecasts) of the expected future competitive, operating and regulatory environments and related financial performance of Golden and ECU. BMO Capital Markets was not asked to and did not consider the possible effects of any litigation or other legal claims. BMO Capital Markets further assumed that the Transaction will have the tax consequences described in discussions with, and materials furnished to BMO Capital Markets by, representatives of Golden. BMO Capital Markets also assumed that the Transaction will be consummated in a timely manner and in accordance with the terms of the Arrangement Agreement and Plan of Arrangement without waiver, modification or amendment of any material term, condition or agreement and that all governmental, regulatory and other consents and approvals necessary for the consummation of the Transaction will be obtained without any material adverse effect on Golden or ECU or on the contemplated benefits of the Transaction.

BMO Capital Markets' opinion is necessarily based upon financial, economic, market and other conditions and circumstances as in effect on, and information made available to BMO Capital Markets as of June 23, 2011. BMO Capital Markets disclaims any undertakings or obligations to advise any person of any change in any fact or matter affecting the opinion which may come or be brought to its attention after the date of the opinion.

BMO Capital Markets' opinion does not constitute a recommendation as to any action the board of directors of Golden should take in connection with the Transaction or any aspect thereof and is not a recommendation to any person on how such person should vote with respect to the adoption of the Arrangement Agreement or Plan of Arrangement or with respect to the Share Issuance Proposal. BMO Capital Markets' opinion relates solely to the fairness, from a financial point of view, to Golden of the exchange ratio and the cash consideration. BMO Capital Markets expresses no opinion as to the relative merits of the Transaction and any other transactions or business strategies discussed by the board of directors of Golden as alternatives to the Transaction or the decision of the board of directors of Golden to proceed with the Transaction, nor does BMO Capital Markets express any opinion on the structure, terms or effect of any other aspect of the Transaction or the other transactions contemplated by the Arrangement Agreement. BMO Capital Markets is not an expert in, and its opinion does not address, any of the legal, tax or accounting aspects of the proposed Transaction, including, without limitation, whether or not the transactions contemplated by the Arrangement Agreement constitute a change of control under any contract or agreement to which Golden, ECU or any of their respective subsidiaries is a party. BMO Capital Markets relied solely on Golden's legal, tax and accounting advisors for such matters.

The following is a summary of the material analyses performed by BMO Capital Markets in connection with its opinion to the Golden board of directors dated June 23, 2011. The following summary, however, does not purport to be a complete description of the financial analyses performed by BMO Capital Markets, nor does the order of analyses described represent relative importance or weight given to those analyses by BMO Capital Markets. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before June 23, 2011 and is not necessarily indicative of current market conditions. Some of the financial analyses summarized below include information presented in tabular format. In order to understand fully BMO Capital Markets' financial analyses, the tables must be read together with the text of the summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data set forth below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of BMO Capital Markets' financial analyses.

Arrangement Consideration. BMO Capital Markets calculated the implied Transaction consideration price per share by multiplying the exchange ratio of 0.05 by the closing price per share of Golden's common stock on the Toronto Stock Exchange of Cdn$19.38 on June 23, 2011, plus the cash consideration of Cdn$0.000394 per share.

To provide background information and perspective with respect to the historical share prices of Golden and ECU, BMO Capital Markets reviewed the share price performance and implied premium or discount to the implied Transaction consideration price per share, based on various time periods ending on June 23, 2011. The following table lists the implied premium or discount for these periods:

Historical Exchange Ratio Analysis. BMO Capital Markets analyzed and reviewed the historical trading price of Golden common stock relative to ECU common shares based on closing prices between June 24, 2008, and June 23, 2011, and calculated the historical exchange ratios during certain periods within those dates implied by dividing the daily closing prices per share of ECU's common shares by those of Golden's common stock, and the average of those historical trading ratios for the various periods reviewed. BMO Capital Markets next compared the exchange ratio of 0.05 provided for in the Transaction with historical exchange ratios for the various periods ending June 24, 2010, and June 23, 2011. The following table lists the implied exchange ratios for these periods:

Days Trading		Implied Exchange Ratio

June 23, 2011			0.0537
Last three months average			0.0452
Last six months average			0.0483
Last twelve months average			0.0530
Golden / ECU Transaction			0.0500

Relative Contribution Analysis. BMO Capital Markets analyzed the contribution of each of Golden and ECU to the pro forma combined company with respect to net asset value (as defined below, the "NAV"), non-GAAP operating cash flow, ounces of production on a silver equivalent basis, measured and indicated resources and total resources on a silver equivalent basis, and current market capitalization. BMO Capital Markets analyzed the operating cash flow and production metrics for projected operating results for the fiscal year ending 2015 provided by Golden management. For the NAV, BMO Capital Markets utilized the projected operating results over the life-of-mine for both Golden and ECU's assets as provided by Golden management. Projected operating results were prepared by Golden and ECU management, respectively, and assumed no cost savings or other synergies.

NAV Overview. To value Golden and ECU's key mining assets, El Quevar and the Velardeña Mining District respectively, BMO Capital Markets relied primarily on a discounted cash-flow ("DCF") analysis whereby it discounted the unlevered, after-tax, constant-dollar free cash flows of each asset over the life of the asset at different discount rates to generate present values. Based on a number of assumptions, each asset's real (or inflation-adjusted) discount rate was estimated and used to calculate the present value of the cash flows. All forecasts of free cash flow were based on Golden's management operating estimates, using consensus research analyst commodity price forecasts, and BMO Capital Markets' assessment thereof in the exercise of its professional judgment.

Under the NAV approach, the value of El Quevar, the Velardeña Properties, and other mining assets are summed to produce a total asset value, from which is added or subtracted the company's financial assets and liabilities as well as an estimate of the present value of corporate general and administrative costs that were not directly assignable to the operating and development assets. The operating assumptions used in the DCF for both El Quevar and the Velardeña Properties are based on Golden's view of these two assets. These projections, as well as other estimates used by BMO Capital Markets in its analyses, were based on numerous variables and assumptions that are inherently uncertain, and accordingly, actual results could vary materially from those set forth in such projects.

Accretion/Dilution Analysis. BMO Capital Markets analyzed the expected pro forma impact of the Transaction on Golden's NAV per share on a fully diluted in-the-money basis, utilizing projections provided by Golden and ECU management teams which excluded any value ascribed to either anticipated expense synergies or further exploration upside. The analysis indicated that the Transaction would be accretive to Golden's stockholders on a NAV per share basis, excluding one-time Transaction costs associated with the transaction. Factoring in the estimated $13.0 million in transaction costs, the Transaction would be dilutive to Golden based on a NAV per share basis.

Miscellaneous. In performing its analyses, BMO Capital Markets made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of BMO Capital Markets, Golden or ECU. Any estimates contained in the analyses performed by BMO Capital Markets are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than those suggested by such analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, as described above, BMO Capital Markets' opinion was only one of several factors taken into consideration by Golden board of directors in making its determination to approve the Arrangement

Table of Contents

Agreement and the Plan of Arrangement. Consequently, BMO Capital Markets' analyses should not be viewed as determinative of the decision of Golden's board of directors or Golden's management with respect to the fairness of the consideration provided for in the Arrangement Agreement and the Plan of Arrangement.

Golden retained BMO Capital Markets as its financial advisor based upon BMO Capital Markets' experience and expertise. BMO Capital Markets is a globally recognized investment banking and advisory firm. Pursuant to the terms of the engagement letter between Golden and BMO Capital Markets, Golden has agreed to pay BMO Capital Markets a transaction fee of approximately $3.5 million, $1.0 million of which was payable upon execution of the Arrangement Agreement and the rendering of its opinion, and approximately $2.5 million of which is contingent upon consummation of the Transaction. Golden also has agreed to reimburse BMO Capital Markets for reasonable expenses incurred by BMO Capital Markets in performing its services and to indemnify BMO Capital Markets and related persons and entities against liabilities, including liabilities under the U.S. federal securities laws, arising out of BMO Capital Markets' engagement.

As part of its investment banking business, BMO Capital Markets is continually engaged in the valuation of businesses and their securities in connection with arrangements and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. BMO Capital Markets has consulted with Golden from time to time on various matters, although none of such prior consultations involved a formal engagement of BMO Capital Markets by Golden. In addition, certain of BMO Capital Markets' affiliates are providing, and may have in the past provided, corporate banking services to Golden, or its affiliates from time to time, and BMO Capital Markets or its affiliates may provide investment and corporate banking services to Golden, ECU and their respective affiliates in the future for which BMO Capital Markets or they may have received or will receive customary fees. BMO Capital Markets provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including derivative securities, of Golden or its affiliates for its own account and for the accounts of customers.

Voting Agreements

During July 2011, ECU entered into a customary voting agreement with each of Golden's executive officers and expects to enter into such agreements with each of Golden's directors prior to the stockholder meeting. The voting agreement represents 271,661 shares of Golden common stock, or approximately 1.8% of the Golden common stock entitled to vote at the stockholder meeting.

Pursuant to these voting agreements, each Golden director and officer party to such agreement committed to vote in favor of approving the Transaction and, among other things, to:

•: not solicit, initiate, facilitate or encourage any inquiries or proposals, participate in any discussions (other than with ECU), approve or recommend, or accept or enter into, any agreement, understanding or arrangement, in respect of an Acquisition Proposal;
•: not sell, transfer, pledge, encumber or otherwise dispose of any Golden securities;
•: not grant any proxy or other right to vote any Golden securities (except to vote in favor of the Share Issuance Proposal and Charter Amendment Proposal) or enter into any voting trust or other agreement with respect to the right to vote Golden securities;
•: not take any action likely to prevent, hinder or delay or interfere with the completion of the Transaction;

Table of Contents

•: not vote any Golden common stock in respect of any proposed action by Golden, the Golden Stockholders or any other person which would likely prevent, hinder or delay the completion of the Transaction;
•: use all commercially reasonable efforts to assist ECU and Golden to complete the Transaction;
•: deliver, and not withdraw, a proxy in respect of all of his or her Golden common stock in support of the Transaction prior to the Golden stockholder meeting;
•: in the event that any transaction other than the Transaction is presented for approval of the Golden stockholders, not vote in favor of, accept, assist or otherwise further the completion of such transaction;
•: not purchase any securities of Golden's subsidiaries; and
•: take all steps as are necessary to ensure that its Golden securities will not be subject to any shareholders' agreements or voting trust or similar agreements affecting its Golden securities or the ability to exercise all voting rights attaching thereto.

Nothing contained in the voting agreements restricts, limits or prohibits a Golden director or officer from exercising his or her fiduciary duties to Golden in his or her capacity as a director or officer of Golden. During July 2011, Golden entered into a customary voting agreement with each of ECU's officers and directors. The voting agreement represents 4,923,226 ECU common shares, or approximately 1.5% of the ECU common shares entitled to vote at ECU's securityholder meeting, and 11,630,000 ECU options to purchase ECU common shares. The voting agreement between Golden and the ECU directors and officers contained provisions relating to the voting of ECU shares by those directors and officers which are substantially the same as those described above.

Court Approval

Under the Business Corporations Act (Québec), the Transaction requires court and ECU securityholder approval. On July 14, 2011, ECU obtained an interim order from the Québec Court providing for the calling and holding of the ECU special meeting and other procedural matters. Subject to receipt of the requisite approvals of the Transaction by ECU and Golden securityholders at their respective special meetings, the hearing in respect of a final order from the Québec Court is expected to take place on or about August 31, 2011.

Canadian Securities Law Matters

ECU is a reporting issuer in all of the provinces of Canada. ECU common shares currently trade on the Toronto Stock Exchange ("TSX") under the symbol "ECU" and the ECU Warrants issued in February 2009 currently trade on the TSX under the symbol "ECU.WT." After the Transaction, ECU common shares and the ECU Warrants will be delisted from the TSX, and Golden will apply to the applicable Canadian securities regulators to have ECU cease to be a reporting issuer. Golden is a reporting issuer in the provinces of Alberta, British Columbia and Ontario. Golden common stock is listed on the TSX under the symbol "AUM" and on the NYSE Amex under the symbol "AUMN." It is a condition of the Transaction that the shares of Golden common stock issued to ECU shareholders pursuant to the Transaction, and which are reserved for issue upon exercise of the Golden Replacement Options and Golden Replacement Warrants, be conditionally approved for listing on the TSX and listed on the NYSE Amex, and that the Golden Replacement Warrants issued to holders of ECU's February 2009 Warrants pursuant to the Transaction be conditionally approved for listing on the TSX.

The issuance of Golden common stock, Golden Replacement Options and Golden Replacement Warrants pursuant to the Transaction, and the issuance of Golden common stock upon the exercise of such Golden Replacement Options and Golden Replacement Warrants, will constitute distributions of

Table of Contents

securities which are exempt from the prospectus requirements of Canadian securities laws. Such Golden common stock, Golden Replacement Options and Golden Replacement Warrants may be resold in each province and territory of Canada, provided: (i) that Golden is a reporting issuer in a jurisdiction of Canada for the four months immediately preceding the trade; (ii) the trade is not a "control distribution" as defined National Instrument 45-102, Resale of Securities as adopted by the Canadian Securities Administrators; (iii) no unusual effort is made to prepare the market or create a demand for those securities; (iv) no extraordinary commission or consideration is paid in respect of that trade; and (v) if the selling security holder is an insider (as such terms are defined in the Canadian securities laws) or officer of Golden, the insider or officer has no reasonable grounds to believe that Golden is in default of Canadian securities laws.

Interests of, and Potential Payments to, Directors and Officers in Connection with the Transaction.

In considering the recommendation of the Golden board of directors that Golden stockholders vote to approve the Share Issuance Proposal, you should be aware that our directors and executive officers have interests in the Transaction that may be different from, or in addition to, those of our stockholders generally. The board of directors of Golden was aware of and considered these potential interests, among other matters, in evaluating, negotiating and approving the Arrangement Agreement and the Plan of Arrangement, and in recommending the approval of the Share Issuance Proposal.

Pursuant to Golden's 2009 Equity Incentive Plan (the "Incentive Plan"), any unvested awards made under the Incentive Plan (including stock options, restricted stock and restricted stock units) will vest immediately prior to the closing of any transaction in which stockholders of Golden immediately prior to the transaction own less than 50% of the outstanding voting power of the company following the transaction. At the time of the Transaction, each of Golden's executive officers will hold unvested stock options and/or restricted stock pursuant to the Incentive Plan. In addition, each of Golden's non-executive directors will hold unvested stock options pursuant to the Incentive Plan and unvested restricted stock units pursuant to Golden's Non-Employee Directors Deferred Compensation and Equity Award Plan, which was established under the Incentive Plan. Because the Transaction will result in ECU shareholders owning at least 51% of the voting power of the combined company, all such unvested stock options, restricted stock, and restricted stock units will vest immediately prior to the consummation of the Transaction in accordance with the terms of the Incentive Plan.

In addition, we have entered into a change of control agreement with each of our executive officers. The change of control agreements contain "double trigger" severance provisions pursuant to which certain payments will be made to the executive if his or her employment is terminated by us or the surviving company, as applicable, without cause, or by the executive with good reason, within two years following a change of control. For purposes of these agreements, "cause" is defined to include a substantial and repeated failure to perform duties as reasonably directed by the board of directors, and "good reason" is defined to include certain adverse changes in the nature or status of the executive's duties or certain decreases in the compensation of the executive. Because the Transaction will result in ECU shareholders owning at least 51% of the voting securities of the combined company, the closing of the Transaction will constitute a change of control under the agreements. Payments made under the agreements are based on a multiple of the executive's salary and target bonus. Our Chief Executive Officer would be entitled to receive three times his salary and target bonus and each of the other executive officers would be entitled to receive two times his or her salary and target bonus. In order to ensure that our executives actually receive the intended benefits, the change of control agreements provide that we will reimburse the executive officers for the amount of the excise tax, if any, imposed on the change of control benefits under Internal Revenue Code Section 4999. This payment will be equal to an amount such that after the executive officer timely pays the excise tax, his or her liability for all taxes would be the same as if this tax had not applied. Receipt of benefits upon termination

Table of Contents

would be subject to the execution of a general release of claims by the executive officer or his or her beneficiary.

We do not expect the employment of any of our executive officers to be terminated in connection with the Transaction, and therefore do not expect to make any severance payments under the change of control agreements unless a qualifying termination subsequently occurs within two years of the closing of the Transaction.

Summary of Potential Payments to Golden's Directors and Officers

Golden's directors will not receive any payments in connection with the Transaction. In connection with the Transaction, unvested restricted stock units held by our non-employee directors will vest. Directors will not be entitled to receive any shares vesting, but will be entitled to receive common stock upon retirement from the Board. Each non-employee director currently holds restricted stock units which will entitle such director to receive 2,871 shares of common stock. All of such awards will vest in connection with the Transaction.

The following table indicates the estimated dollar amounts payable to Golden's named executive officers under the Incentive Plan and the change of control agreements described above upon the completion of the Transaction, assuming completion of the Transaction on September 2, 2011. Pursuant to SEC rules, amounts shown in the "cash," "perquisites/benefits" and "tax reimbursement" columns reflect an assumption that a qualifying termination of each executive's employment will occur contemporaneously with the closing of the Transaction. As described above, we do not expect the employment of any of our executive officers to terminate in connection with the Transaction, and therefore do not expect to make these payments unless a qualifying termination subsequently occurs within two years of the closing of the Transaction. Amounts shown in the "equity" column reflect the aggregate dollar value of previously awarded stock amounts and in-the-money option awards that will vest upon the closing of the Transaction, and are not new equity awards.

Deborah J. Friedman	480,000	397,354	0	—	(4)	0	877,354

(1): Represents a multiple of the executive officer's base salary and target bonus as described above; the relevant amount must be paid in a lump sum within 10 business days after the date of termination of employment. Amounts in this column will not be paid unless a qualifying termination occurs within two years following the Transaction.
(2): Represents the aggregate dollar value of stock awards, and in-the-money option awards, for which vesting will occur upon the closing of the Transaction, assuming a per share price of $18.32 for Golden common stock (the average closing market price on the NYSE Amex over the first five business days following the first public announcement of the Transaction on June 24, 2011). Amounts in this column vest regardless of whether there is a concurrent or subsequent termination event.
(3): Following a qualifying termination, we will pay, on each executive's behalf, the portion of premiums of Golden's group health insurance, including coverage for his or her eligible dependents, that Golden paid immediately prior to the date of termination ("COBRA Payments")

Table of Contents

for the period that such executive is entitled to coverage under COBRA, but not to exceed 36 months for Mr. Clevenger and 24 months for the other identified executives. We will pay such COBRA Payments for the executive's eligible dependents only for coverage for those dependents that were enrolled immediately prior to the date of termination. The executive will continue to be required to pay that portion of the premium of his health coverage, including coverage for eligible dependents, that he was required to pay as an active employee immediately prior to the date of termination. If the executive is for any reason not eligible for coverage under COBRA for the full 24 or 36 month period, as applicable, we will pay to the executive a lump sum in an amount equal to the product of (i) the amount of the COBRA payment paid on his behalf for the final month of the COBRA Period and (ii) the number of months by which the executive's period of COBRA coverage was less than 24 or 36 months, as applicable. Amounts shown in the table above are not discounted to present value. In addition, for the 24-month period immediately following the date of termination, we have agreed to provide to the executive, at a cost not to exceed an aggregate of $5,000, life, disability, and accident insurance benefits substantially similar to those that the executive was receiving immediately prior to the termination of employment. For the purpose of the above table, we have assumed that a benefit in the aggregate amount of $5,000 will be provided for the identified executives. Amounts in this column will not be paid unless a qualifying termination occurs within two years following the Transaction.

(4): Since May 2009, Ms. Friedman has devoted approximately half her time to service as our Senior Vice President, General Counsel and Corporate Secretary and approximately half her time to her legal practice at Davis Graham & Stubbs LLP, where she is a partner. Ms. Friedman is not employed by Golden and does not receive health or other insurance benefits from us.

Summary of Potential Payments to ECU Directors and Officers in Connection with the Transaction

ECU has informed Golden that it has entered into a Change of Control Bonus Agreement with each of Michel Roy, the current Chairman and Chief Executive Officer of ECU, and Stephen Altmann, ECU's President. Under the terms of the Change of Control Bonus Agreements, upon consummation of the Transaction, Mr. Roy is entitled to receive Cdn$1.5 million and Mr. Altmann is entitled to receive Cdn$1.25 million. It is anticipated that Mr. Roy will agree to waive this payment and instead receive Cdn$1.5 million in shares of Golden common stock. In addition, as described below, in connection with the anticipated terms of Mr. Altmann's employment with Golden following the Transaction, it is anticipated that Mr. Altmann will waive the benefit of this payment and instead receive Cdn$1.25 million in Golden restricted stock, of which 40%, 40% and 20% would vest on the first, second and third anniversaries, respectively, of the grant date, or 100% upon termination of Mr. Altmann's employment with Golden.

In addition to the Change of Control Bonus Agreements with Messrs. Roy and Altmann, the ECU board of directors has approved a discretionary pool of Cdn$500,000 to be paid, in the discretion of Messrs. Roy and Altmann, to certain officers or employees of ECU upon consummation of the Transaction. The recipients of the payments from this discretionary bonus pool have not been determined, but it is anticipated that Dwight Walker, ECU's Chief Financial Officer, would receive a payment of Cdn$150,000. Neither Mr. Roy nor Mr. Altmann are eligible to receive payments from this

Table of Contents

discretionary bonus pool. Amounts payable to Mr. Roy, Mr. Altmann and Mr. Walker in connection with the Transaction are shown in the table below:

Name

Michel Roy	1,500,000	(1)	—	—	—	—	1,500,000
Stephen Altmann	1,250,000	(1)	—	—	—	—	1,250,000
Dwight Walker	600,000	(2)	—	—	—	—	600,000

(1): As noted above, it is anticipated that Mr. Roy will agree to waive his payment and instead receive Cdn$1.5 million in shares of Golden common stock. In addition, it is anticipated that Mr. Altmann will waive his payment and instead receive Cdn$1.25 million in Golden restricted stock, of which 40%, 40% and 20% would vest on the first, second and third anniversaries, respectively, of the grant date, or 100% upon termination of Mr. Altmann's employment with Golden. The number of shares to be issued to Mr. Roy and Mr. Altmann in lieu of their cash change of control payments will be determined on the closing date based on the five-day volume weighted average price of Golden's common stock on the NYSE Amex immediately prior to such date. Based on the closing price of $17.42 for Golden's common stock on the NYSE Amex on July 26, 2011 (and the currency exchange rate on such date), 91,128 shares would be issued to Mr. Roy and 75,940 shares would be issued to Mr. Altmann.
(2): Amount shown reflects Cdn$450,000 for severance payable to Mr. Walker under the terms of his employment agreement as a result of his termination in connection with the Transaction, and Cdn$150,000 that is anticipated to be awarded to Mr. Walker under the discretionary change of control bonus pool.

In addition to the payments described above, the board of directors of ECU has approved the payment of certain amounts to Messrs. Roy and Altmann, as well as other members of ECU's management team, as compensation for past services. The payments are in lieu of option awards that ECU planned to award to the individuals; ECU had previously concluded that such option awards were not advisable because of ECU's ongoing review of strategic alternatives. The cash payments are equal to Cdn$175,000 for Mr. Roy, Cdn$150,000 for Mr. Altmann, and $100,000 in the aggregate for the remaining members of ECU's management team, as determined in the discretion of Messrs. Roy and Altmann. It is anticipated that ECU will make these payments prior to the consummation of the Transaction. These payments are not contingent upon the completion of the Transaction.

Finally, the board of directors of ECU has approved the payment of certain amounts to each of the two independent directors of ECU as consideration for past services. The cash payments are equal to Cdn$12,000 (representing Cdn$3,000 per quarter for the last four calendar quarters), plus an additional cash payment of Cdn$50,000. This Cdn$50,000 payment is in lieu of option awards that ECU planned to award to the directors. It is anticipated that ECU will make these payments prior to the consummation of the Transaction. ECU advises that these payments are consistent with ECU's ordinary pay practices and are not contingent upon the completion of the Transaction.

Stephen Altmann Employment Arrangements

In connection with the Transaction, Golden intends to offer Mr. Altmann the position of President, with an annual salary of $350,000, an annual target bonus equal to 50% of annual salary and an annual target equity award valued at 100% of annual salary. Mr. Altmann would waive benefits under his Change of Control Bonus Agreement with ECU and the Cdn$1.25 million bonus to be paid by ECU upon completion of the Transaction, and would instead receive Cdn$1.25 million in Golden restricted stock, of which 40%, 40% and 20% would vest on the first, second and third anniversaries, respectively,

Table of Contents

of the grant date, or 100% upon termination of Mr. Altmann's employment for any reason. The number of shares to be issued to Mr. Altmann in lieu of his cash change of control payment will be determined on the closing date based on the five-day volume weighted average price of Golden's common stock on the NYSE Amex immediately prior to such date. Based on the closing price of $17.42 for Golden's common stock on the NYSE Amex on July 26, 2011 (and the currency exchange rate on such date), 75,940 shares would be issued to Mr. Altmann. Mr. Altmann would be offered a change of control agreement on the same terms as the change of control agreements with Golden's other executive officers, including an enhanced severance payment of 200% of target salary and bonus in the event of termination following a change of control, and would be eligible to participate in all other benefits available generally to all salaried employees of Golden.

Mr. Altmann's responsibilities initially, in conjunction with Mr. Clevenger, would be the development and implementation of the growth plans of the combined company. Mr. Altmann would also have primary responsibility for investor relations.

Pro Forma Economic Ownership of Golden

Upon completion of the Transaction, we estimate that former stockholders of ECU will own approximately 51% of the outstanding common stock of the combined company and that current Golden stockholders will own approximately 49%, assuming that no outstanding ECU options and warrants and any Replacement Options and Replacement Warrants are exercised before the consummation of the Transaction. Assuming that all such warrants and options are exercised before the consummation of the Transaction, former stockholders of ECU would own approximately 55% of the outstanding stock of the combined company on a fully diluted basis, while the current Golden stockholders would own approximately 45%.

Dissenting Stockholder Rights

Under applicable Delaware laws and U.S. securities laws, Golden stockholders are not entitled to dissenters' appraisal rights with respect to any matters to be acted upon at the Golden special meeting. Any registered holder of ECU common shares who properly dissents at the ECU special meeting in accordance with the Business Corporations Act (Québec) and the Plan of Arrangement will be entitled, in the event the Transaction becomes effective, to be paid by Golden, in accordance with the terms of the Plan of Arrangement, the fair value of the ECU common shares held by such dissenting ECU stockholder, determined by the Québec Court as of the close of business on the day before the ECU stockholder approval of the Transaction is obtained. If ECU shareholders holding greater than 5% of the outstanding ECU shares exercise dissenters' rights, Golden will not be obligated to consummate the Transaction.

Fees, Costs and Expenses

Except as otherwise noted herein, all fees, costs and expenses incurred in connection with the Transaction will be paid by the party incurring those expenses.

Accounting Treatment

Golden will account for the Transaction under U.S. GAAP as an acquisition of ECU by Golden. As required under U.S. GAAP, we considered all pertinent facts and circumstances in identifying Golden as the acquiring entity for accounting purposes. These facts and circumstances include the relative voting rights in the combined company of former holders of ECU common shares and holders of Golden common stock prior to the combination, the composition of the board of directors of the combined company and the terms of the exchange of Golden common stock for ECU common shares. The purchase price will be allocated to ECU's identifiable assets and liabilities based on their estimated

Table of Contents

fair market values at the date of the completion of the Transaction, and any excess of the purchase price over those fair market values will be allocated to mining properties. Final valuations of property, plant and equipment, mining properties and intangible and other assets have not yet been completed as management is still reviewing the existence, characteristics and useful lives of ECU's tangible and intangible assets. The completion of the valuation work could result in significantly different amortization expenses and balance sheet classifications. After completion of the Transaction, the results of operations of ECU will be included in the consolidated financial statements of Golden.

Supplemental Listings on NYSE Amex and TSX

In connection with the Transaction, Golden has agreed to obtain conditional listing approval from the NYSE Amex and the TSX for the Golden common stock that will be issued in the Transaction, including the Golden common stock issuable upon exercise of the Golden Replacement Options and Golden Replacement Warrants. Golden has also agreed to obtain conditional approval for the listing and posting for trading on the TSX of the Golden Replacement Warrants issued to replace the February 2009 ECU Warrants.

Issuance and Resale of Golden Common Stock

The Golden common stock to be issued pursuant to the Transaction has not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction. The Golden common stock to be issued in the Transaction will be issued pursuant to an exemption from the prospectus requirements of Canadian securities law and from the registration requirements provided by Section 3(a)(10) of the Securities Act based on the approval of the Plan of Arrangement by the Québec Court.

Section 3(a)(10) of the Securities Act exempts securities issued in exchange for one or more bona fide outstanding securities from the general requirement of registration where the fairness of the terms and conditions of the issuance and exchange of the securities have been approved by any court or authorized governmental entity, after a hearing upon the fairness of the terms and conditions of exchange at which all persons to whom the securities will be issued have the right to appear and to whom adequate notice of the hearing has been given. If the Québec Court approves the Plan of Arrangement, its approval will constitute the basis for the Golden Replacement Options and Golden Replacement Warrants to be issued without registration under the Securities Act in reliance on the exemption from the registration requirements of the Securities Act provided by Section 3(a)(10) of the Securities Act.

On July 14, 2011, the Québec Court issued the interim order and, subject to the approval of the Plan of Arrangement by the ECU Securityholders and the approval of the Share Issuance Proposal by the Golden stockholders, a hearing for the Québec Court's final order on the fairness of the Transaction will be held on or about August 31, 2011.

Section 3(a)(10) of the Securities Act does not exempt the issuance of Golden common stock upon exercise of the Replacement Options or Replacement Warrants from the registration requirements of the Securities Act. Accordingly, pursuant to the terms of the Arrangement Agreement, Golden has agreed to file with the SEC a registration statement on Form S-8 and a registration statement on Form S-3 to register the Golden shares issuable upon the exercise of the Replacement Options and Replacement Warrants, respectively.

Any such certificate formerly representing ECU Shares or ECU Warrants not duly surrendered on or before the sixth anniversary of the Effective Date shall cease to represent a claim by, or interest of, any former holder of ECU Shares or ECU Warrants of any kind or nature against or in ECU or Golden and be deemed to have been surrendered to Golden and shall be cancelled.

(e): No holder of ECU Securities shall be entitled to receive any consideration with respect to its ECU Securities other than the Consideration in accordance with the Plan of Arrangement and, for greater certainty, no such holder will be entitled to receive any interest, dividends, premium or other payment in connection therewith.

Withholding Rights

Golden, ECU and the Depositary, as applicable, shall be entitled to deduct and withhold from any Consideration payable or otherwise deliverable to any former holder of ECU Securities such amounts as they may be required to deduct and withhold therefrom under any provision of applicable Laws in respect of applicable taxes. Any such deducted and withheld amounts shall be treated as having been paid to the person to whom such amounts would otherwise have been paid.

No Fractional Securities will be issued

No fractional shares of Golden common stock, fractional Golden Replacement Options or fractional Golden Replacement Warrants shall be issued to any person pursuant to the Plan of Arrangement. Instead, the number of shares of Golden common stock or the number of Golden Replacement Options or Golden Replacement Warrants to be issued to any person shall be rounded up or down, as applicable, to the nearest whole share of Golden common stock. In calculating such fractional interests, all ECU Shares, ECU Options or ECU Warrants, as applicable, registered in the name of or beneficially held by an ECU Securityholder or its nominee shall be aggregated.

No dividend or other distribution declared or paid after the Effective Time with respect to Golden common stock shall be delivered to the holder of any certificate formerly representing ECU Shares unless and until the holder of such certificate shall have complied with the provisions of the Plan of Arrangement in respect of the surrender of such certificates. Subject to applicable law and to the Plan of Arrangement, at the time of such compliance, there shall, in addition to the delivery of the Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of any dividend or other distribution declared or made after the Effective Time with respect to the Golden common stock to which such holder is entitled in respect of such holder's Consideration.

The Arrangement Agreement contains representations and warranties made by ECU and Golden.

Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the Arrangement Agreement.

On June 24, 2011, ECU and Golden entered into the Arrangement Agreement, pursuant to which ECU and Golden agreed that, subject to the terms and conditions set forth in the Arrangement Agreement, Golden will acquire all of the issued and outstanding ECU Shares, ECU Options and ECU Warrants. As a result of the Transaction, each ECU Shareholder (other than Dissenting Shareholders and Golden) will receive 0.05 of a share of Golden common stock and $0.000394 in cash for each ECU Share held. The terms of the Arrangement Agreement are the result of arm's length negotiation between ECU and Golden and their respective advisors.

Following completion of the Transaction, Golden plans to continue to operate the mines on the Velardeña Properties and to advance the expansion of these operations as currently being considered by ECU. In 2010, the mines on the Velardeña Properties produced approximately 380,000 ounces of silver, 10,000 ounces of gold, 182,000 pounds of zinc, and 155,000 pounds of lead. In the first quarter of 2011, the mines on the Velardeña Properties produced approximately 79,000 ounces of silver, 1,900 ounces of gold, 43,000 pounds of zinc, and 47,000 pounds of lead. Golden has developed a plan to test potential improvements to the grinding and process controls and optimization of certain circuit retention times that could result in low cost productivity improvements in the existing oxide plant. Golden is developing a plan for grade control in the mines that could improve the grade of ore processed through the oxide plant.

Golden has developed a metallurgical testing plan focused on improving metal recoveries and product (concentrate) qualities for the planned sulfide plant. Golden intends to conduct various test work to determine optimal metallurgical characteristics of both the oxide and sulfide ores. For the planned sulfide plant, crushing, grinding and flotation parameters would be examined to produce a process flow sheet which optimizes value from the silver, gold, lead and zinc minerals contained in the deposit. Following completion of this work, Golden expects to produce a NI 43-101 compliant Preliminary Economic Assessment. Current target production rates for the anticipated new sulfide plant are approximately 2000 tonnes per day. Golden's current preliminary estimate of the cost to complete a 2000 tonne per day sulfide plant and associated 7500 meters of underground mine development is approximately $120 million, with testwork, engineering and construction and mine development being completed over about a three year period. The new sulfide plant is currently expected to produce annually approximately 4 million silver ounces, 70,000 gold ounces and 15 to 20 million pounds each of lead and zinc. Golden currently expects that the existing oxide plant would continue to operate while the new sulfide plant is built and may continue to operate following commencement of production from the new sulfide plant.

Golden's El Quevar Project, Salta, Argentina

Golden has been focused on advancing its El Quevar silver project and has completed more than 820 meters of development drifting. The drifting has encountered a large number of mineralized structures believed to be tension faults that were not anticipated in the current model of the El Quevar deposit, in which mineral concentrations are modeled to follow the alteration envelope. As a result, we decided to delay completion of a NI 43-101 compliant Preliminary Economic Assessment and a planned mid-year 2011 resource update to allow further work to assess the impact that these newly discovered structures may have on the mining plan and global El Quevar resource.

Table of Contents

work has been completed, as the open pit would encompass the area through which the drift would advance. Golden has targeted the fourth quarter 2011 for a resource update based on the bulk mining studies. If these efforts are successful, Golden plans to proceed with a NI 43-101 compliant Preliminary Economic Assessment in the first half of 2012.

Golden's Pánuco Exploration Target, Zacatecas, Mexico

Golden has commenced a third drilling program at its Pánuco exploration target at the Zacatecas properties in the state of Zacatecas, Mexico. Results from the first two rounds of drilling have identified a vein system striking one and a half kilometers with silver grades up to one kilogram per tonne over more than a meter. More than 70 percent of the approximately 48 holes drilled in the first two drilling programs encountered silver mineralization averaging about 270 grams of silver per tonne. The third drilling program is planned to include an additional 40 to 50 holes for a total of approximately 100 holes. Golden expects that the results of the three drilling programs will support preparation of a NI 43-101 compliant estimate in the first half of 2012.

Other Golden Exploration Properties

Golden is also advancing other exploration properties, and is currently focused on the three prospects described below.

At the Cochabamba silver prospect in the Ancash Province of Peru, Golden is preparing for a 10 hole program to test an outcropping vein system of more than 1.5 kilometers in length characterized by quartz and carbonate vein material containing gold, silver and base metals. Surface and limited underground sampling has returned up to 10 grams per tonne gold, 450 grams per tonne silver and more than 3% combined lead and zinc. A similar occurrence ten kilometers to the northeast is characterized by a high grade resource averaging 17 grams per tonne gold and 450 grams per tonne silver.

At the Atlas gold prospect in the Santa Cruz Province of Argentina, Golden is conducting field geologic work to prepare for a 10 to 20 drill hole program prior to year-end 2011. Golden has identified a system at Atlas characterized by epithermal veins in a zone about 1.5 kilometers in length and 40 meters width where surface channel sampling has returned gold values ranging from 0.5 grams to 10 grams per tonne gold.

At the La Pinta prospect, directly south of Goldcorp's Penasquito mine in Zacatecas state, Mexico, Golden is conducting a geophysical survey in an attempt to define the source of intrusive float anomalous in zinc and silver and up to three grams per tonne gold found on the top of a ridge in the center of the property. Depending on the results of this survey, Golden may drill the prospect in the later part of the year.

Directors and Officers of the Combined Company

The current directors and officers of Golden will continue to serve as the directors and officers of Golden after the completion of the Transaction, with the following changes:

•: Michael T. Mason, a current director of ECU, will join the board of directors of Golden, bringing the total number of directors to seven. Mr. Mason has more than 35 years experience in the minerals industry.

•: Michel Roy, the current chairman and chief executive officer of ECU, will act as a senior consultant to Golden.

Capital Structure

If the Charter Amendment Proposal is not approved by our stockholders at the special meeting, or if the Charter Amendment Proposal is approved but the Share Issuance Proposal is not approved, the authorized capital of Golden will continue to consist of 50,000,000 shares of common stock, $0.01 par value, and 10,000,000 shares of preferred stock, $0.01 par value. If the Charter Amendment Proposal is approved by our stockholders at the special meeting and the Transaction is consummated, the authorized capital of Golden will consist of 100,000,000 shares of common stock, $0.01 par value, and 10,000,000 shares of preferred stock, $0.01 par value. In either event, the rights and restrictions of the classes of capital stock of Golden will not be affected by the Transaction.

In connection with the Transaction, ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each ECU common share held immediately prior to the consummation of the Transaction. As of June 24, 2011, the date of the Arrangement Agreement, ECU had 317,081,333 shares outstanding and an additional 3,000,000 shares were issued by ECU after that date as payment for the prior exercise of an option to purchase an exploration property. Assuming that no ECU options or warrants are exercised after June 24, 2011, ECU would have 320,081,333 shares outstanding, and Golden would issue approximately 16,004,066 shares to ECU shareholders at closing. The exact number of shares issued at closing will be subject to adjustment for rounding. In addition, an estimated 167,068 shares of Golden common stock would be issued, in the aggregate, to Mr. Roy and Mr. Altmann in lieu of their cash change of control payments. The exact number of shares to be issued will be determined on the closing date based on the five-day volume weighted average price of Golden's common stock on the NYSE Amex immediately prior to such date. Also, as further discussed below, assuming that none of the ECU options or warrants are exercised prior to the closing date, 661,750 Golden shares would be issuable upon exercise of Golden Replacement Options and 2,218,292

Golden Replacement Options

As of June 24, 2011, ECU had a total of 13,235,000 outstanding options to purchase common shares. All ECU options are vested and currently exercisable.

Effective at the closing of the Transaction, Golden plans to adopt a stock option plan containing substantially the same terms as the existing ECU Stock Option Plan, and the Golden Replacement Options will be issued pursuant to this plan. Other than the Golden Replacement Options, no awards will be made pursuant to this plan.

The ECU options were issued to employees, directors or consultants of ECU. Upon termination of employment or other service to the company, the ECU options are exercisable until the earlier of (i) the original expiration date for the options, (ii) 90 days following the termination of employment or service (or, for persons engaged in certain investor relations activities, 30 days following termination of employment or service), or (iii) in the event of the optionholder's death, 12 months following the date of death. The expiration date of the Golden Replacement Options will be identical to the expiration date of the ECU options for which they are exchanged, provided, however, that the Golden Replacement Option Plan will provide that if any optionholder ceases to be an employee, officer, director or consultant of ECU within 180 days following the closing date, the expiration date for the Golden Replacement Options held by such person will be the earlier of (i) the original expiration date for the options, or (ii) two years following the closing date.

If none of the ECU options are exercised prior to the closing date, the Golden Replacement Options issued to the optionholders would be issuable for an aggregate of approximately 661,750 shares of Golden common stock. The exact number of shares issuable upon exercise of the Golden

Unaudited Pro Forma Combined Condensed Financial Statements

The Golden unaudited pro forma combined condensed financial information as of March 31, 2011, for the three-month period then ended and for the fiscal year ended December 31, 2010, is attached as Annex E to this proxy statement. The pro forma financial information is presented to show the results of operations and financial position of Golden as if the Transaction had occurred as of January 1, 2010, and with respect to the balance sheet, as if the Transaction had occurred as of March 31, 2011.

Liquidity and Capital Resources of the Combined Company

At March 31, 2011 our aggregate cash and short-term investments totaled $106.1 million, which included $104.3 million of cash and cash equivalents and $1.8 million of short-term investments. Our cash and short-term investment balance is lower than the $121.6 million in similar assets held at December 31, 2010 due to approximately $16.9 million spent during the three months ended March 31, 2011 on the El Quevar project, exploration and general and administrative activities, including changes

Table of Contents

in working capital, offset partially by the receipt of approximately $1.4 million of common shares in Apogee Silver Ltd. ("Apogee") in connection with our sale to Apogee of the Golden subsidiary holding the Paca Pulacayo property.

As of July 13, 2011, Golden held Cdn$15.0 million of ECU 0.0% senior unsecured convertible notes, which it received in exchange for Cdn$15.0 million of cash invested in ECU through a private placement. The proceeds of the convertible notes are intended to be used by ECU for general corporate purposes and for ongoing exploration, development, and operations at Velardeña until closing of the proposed Transaction, to the extent that current ECU cash flows from the sale of doré and concentrates are not sufficient to fund those expenditures. Among the ECU expenditures which may be funded from the proceeds of the convertible notes are expenditures related to the Transaction and for scheduled debt service. Golden anticipates that ECU's current cash flow from sales will be sufficient to fund ongoing operations at Velardeña until closing of the Transaction. However, Golden anticipates that prior to closing ECU will spend approximately Cdn$12.5 million of the proceeds from the convertible notes for costs related to exploration and capital equipment at Velardeña, ECU corporate overhead, debt service, and costs related to the Transaction, including bankers and attorneys fees. Following the closing of the Transaction, the remaining Cdn $2.5 million of proceeds from the convertible notes would, unless used for other purposes, be available for Golden's general use.

With our cash and investment balance at March 31, 2011 of $106.1 million, and assuming that we are able to close the Transaction prior to the end of September 2011, we plan to spend the following amounts during the remaining nine months of 2011 pursuant to our long-term business strategy:

•: Approximately $12.5 million for corporate overhead, debt service and costs related to the Transaction incurred by ECU, reflected as a drawdown of proceeds from the $15.0 million ECU convertible note held by Golden;
•: Approximately $5.0 million of costs related to the Transaction incurred by Golden;
•: Approximately $22.0 to $25.0 million to be incurred at our El Quevar project to fund the continuation of exploration drilling, underground drifting, and related technical engineering and project assessment to further define the extent of the resource before completing an economic study. This amount could be reduced if we conclude that the advancement of the underground drift is no longer necessary as referenced in "—Business of the Combined Company—Golden's El Quevar Project, Salta, Argentina.";
•: Approximately $4.0 million of costs related to the advancement of feasibility work at ECU's Velardeña project following closing of the Transaction (Golden estimates that operating and continued development costs at Velardeña will be funded from the sale of doré and concentrates produced from ongoing Velardeña operations);
•: Approximately $12.0 million during the remainder of 2011 to fund the drilling of two targets in Argentina, three in Peru and four in Mexico, and on other generative exploration activities and property holding costs related to our portfolio of exploration properties conducted through our principal exploration offices located in South America and Mexico. Additional spending is possible for early and advanced stage drilling programs, depending on the success of our targeted exploration program and generative exploration activities;
•: Approximately $9.0 million during the remainder of 2011 on debt service and the reduction of other short term liabilities relating to obligations of ECU acquired in the Transaction;
•: Approximately $7.0 million during the remainder of 2011 on general and administrative costs;
•: Approximately $2.0 million during the remainder of 2011 on working capital and other general corporate purposes.

Table of Contents

We plan to fund the expenditures described above from our cash and investment balances at March 31, 2011 of $106.1 million and from approximately $0.3 million from royalties and other income through the end of 2011. Based on these projections we would end the year 2011 with cash and investment balances of approximately $30.0 to $33.0 million.

The actual amount that we spend through the end of 2011 may vary significantly from the amounts specified above, and will depend on a number of factors, including the results of our continued exploration activities and project assessment work at El Quevar and our other exploration properties, and the results of continuing operations and further development work and project assessment work at Velardeña. There can be no assurance the expenditures planned for El Quevar or Velardeña will demonstrate the economic viability of either project.

If economic studies at either the El Quevar or Velardeña projects are positive, significant additional capital would be required to complete development and plant construction associated with the projects. To fund completely either project or other exploration drilling programs beyond 2011 we will have to raise additional capital or enter into other financing arrangements. The Sentient Group has expressed an interest in investing further capital in the combined company in order to maintain its current ownership of approximately 19%, which could generate approximately $67.0 million in additional cash at $17.42 per share, which was Golden's closing stock price on the NYSE Amex on July 26, 2011. However, no agreement has been reached with Sentient, and it is uncertain whether an additional investment by Sentient will occur, the number of Golden shares that would be purchased, or the amount of cash that would be generated by the investment if it were to occur. There can be no assurance that we will be successful in raising additional capital or obtaining financing in the future on terms acceptable to us or at all. In addition, if we are required to immediately repay the term loan facility of ECU or if other unanticipated costs arise, this may significantly reduce the amount of cash that we currently expect to have available for the above uses on the schedule we currently anticipate. If we are unable to obtain additional capital or alternative financing arrangements during 2011 or beyond, the potential development of the El Quevar or Velardeña projects could be delayed following the completion of economic studies and we may have to significantly reduce spending on other exploration projects to preserve cash.

Golden Documents Incorporated by Reference

The SEC allows Golden to incorporate by reference information into this proxy statement. This means that Golden may disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference is considered to be a part of this document, except for any information that is superseded by information that is included directly in this document or incorporated by reference subsequent to the date of this document. See "Additional Information—Where Stockholders Can Find More Information About Golden" on page 95.

El Quevar

Our El Quevar silver project is located near Nevado Peak in the San Antonio de los Cobres municipality, Salta province, in the Altiplano region of northwestern Argentina.

The Yaxtché deposit is one of three primary targets currently identified at the El Quevar project. As of July 1, 2011, Golden has completed approximately 80,270 meters of diamond drilling in 330 drill holes. Of these holes, 227 were drilled to test the main Yaxtché zone for potential mineralization, with about 70% of the holes intersecting significant silver mineralization. Golden's work indicates that the Yaxtché central zone is at least 650 meters in strike length, with other drilling results to the east and west indicating a total length of more than 1,500 meters, and between 40 to 150 meters in width. Golden's drilling further indicates that the silver mineralization is continuous laterally and to depths of 350 meters below surface in the main area.

As of July 1, 2011, we have also completed more than 820 meters of development drifting at El Quevar and have advanced approximately 600 meters along strike in the central Yaxtché zone. The drifting has encountered more than 40 mineralized structures believed to be tension faults that were not anticipated in the current modeling of the El Quevar deposit, in which mineral concentrations are modeled to follow the alteration envelope. Although the structures are narrow, generally less than a quarter of a meter in width, results from detailed sampling show that the structures tend to be of substantial grade, typically in excess of one kilogram per tonne of silver. We are conducting uniform channel sampling of the structures and the alteration envelope. Our evaluation of the features seen in the development drift should contribute to the understanding of these newly discovered structures and provide further information regarding confirmation of the mine model. We decided to delay completion of a NI 43-101 compliant Preliminary Economic Assessment and a planned mid-year 2011 resource update to allow further work to assess the impact that these newly discovered structures may have on the mining plan and global El Quevar resource.

Table of Contents

As part of this effort, Golden is currently examining the bulk mining potential of the Yaxtché zone at El Quevar. Preliminary engineering indicates that an open pit could be feasible on the eastern end of the Yaxtché zone and Golden is performing an optimization analysis of the potential pit. Following completion of these analyses, Golden will examine the potential for bulk underground mining of the higher grade western zone. We may reduce our level of activity in advancing the drift until this work has been completed, as the open pit would encompass the area through which the drift would advance. Golden has targeted the fourth quarter 2011 for a resource update based on the bulk mining studies. If these efforts are successful, Golden would proceed with a NI 43-101 compliant Preliminary Economic Assessment in the first half of 2012.

In addition to further in-fill drilling on the Yaxtché deposit, we have completed a first-phase drill program on the ManiSub target, which is located approximately 500 meters southwest of the Yaxtché deposit, and may also conduct additional drilling on the Carmen target, located approximately 500 meters north of the Yaxtché deposit.

Property Description and Location

The Velardeña Properties are comprised of three properties held by ECU within the Velardeña mining district. The three properties which collectively represent the Velardeña Properties are the Velardeña property, the Chicago property and the San Diego property.

The Velardeña Properties are located in the Velardeña mining district, within the municipality of Cuencamé, in the northeast quadrant of the State of Durango, Mexico. The property is situated approximately 95 kilometers southwest of the city of Torreón in the State of Coahuila and 140 kilometers northeast of the city of Durango, capital of the State of Durango.

The Velardeña property contains the Santa Juana mine, which has been the focus of ECU's mining efforts since 1995, as well as the Terneras, San Juanes and San Mateo mines.

The Chicago property is located approximately 2 kilometers south of the Velardeña property and contains the historical Los Muertos-Chicago mine, the extension of which is being drilled by ECU.

The San Diego property is situated approximately 9 kilometers northeast of the Velardeña property and contains the La Cruz-La Rata and El Trovador mines as well as a number of other shallower shafts which were sunk on narrower veins such as the Cantarranas, Montanez and El Jal. The San Diego property is subject to a joint venture agreement between ECU and Golden Tag Resources Ltd with each company holding 50% of the joint venture. The operations of the joint venture are currently being managed by an outside third-party contractor.

ECU holds the Velardeña Properties through its wholly-owned Mexican subsidiaries, Minera William S.A. de C.V. and BLM Minera Mexicana S.A. de C.V. At present, the three properties comprise a total of 33 mineral concessions (20 for the Velardeña property, 9 for the Chicago property and 4 for the San Diego property). The mineral concessions in each of the properties vary in size and the concessions comprising each mineral property are contiguous.

Accessibility, Climate, Local Resources, Infrastructure and Physiography

The Velardeña Properties are located in the State of Durango approximately 95 kilometers southwest of the city of Torreón and 140 kilometers northeast of the city of Durango. A four-lane toll highway connecting Torreón and Durango passes approximately 500 meters east of the village of

Table of Contents

Velardeña. In addition, the village of Velardeña is connected to a free two-lane highway via a 3 kilometers paved road from the highway. The village is connected to the mine site via a 7 kilometers gravel road.

The area in which the Velardeña Properties are situated is considered to be a semi-arid region which is predominantly semi-hot and dry. From a physiographical point of view, the zone is mature with a mixed topography. Streams within the area drain either to internal drainage systems or tributaries of the Nazas and Aguanaval rivers which are connected to the Laguna de Mayrán. All of the streams are intermittent and short lived during the rainy season only. A series of water dams were built over the years to control water flow from the two rivers for irrigation and water management purposes. The Francisco Zarco dam, located 25 kilometers to the west, is the closest to the Velardeña Properties.

ECU owns a 250 tonne-per-day flotation mill situated near the town of Velardeña which has been extensively upgraded and is now capable of milling up to 340 tonnes per day. The mill has a fully operational lead and zinc flotation circuit and has a recently commissioned pyrite circuit to recover more gold and silver from the sulfide ore. Furthermore, ECU has acquired an 80 tpd flotation mill adjacent to its mill to use either for large scale metallurgical testing or for processing specific ores different from the main feed.

In 2009, ECU purchased a conventional cyanide leach mill with a Merrill Crowe precipitation circuit. The mill, which is located approximately two kilometers from the Santa Juana mine site and adjacent to its Chicago property, is used to process oxide material from the Velardeña property. ECU generates gold/silver doré bars from the mill which are sold to a third party refinery. The mill has a rated capacity to process mineralized material up to 500 tonnes per day.

History

Mining has played an important role in Mexico since pre-historic times, but it entered a period of rapid expansion after the Spanish conquest when rich mineral deposits were found. The wealth found in these early mines served as an incentive for the early colonizers to locate to more remote and poorly accessible portions of the country.

It is not known if the indigenous peoples or the Spanish colonists first began mining in the Velardeña district but exploration and mining extends back to at least the late 1500's or early 1600's. The mines were first worked by the Spanish, with the high-grade ore mined by hand and processed on a small scale by direct smelting.

Historical and Present Mining

The Velardeña mining district and the area contained within ECU's Velardeña Properties are riddled with mine openings and old workings, in a somewhat haphazard fashion near surface, representing the earliest efforts at extraction, and more systematic at depth, which is indicative of later, better organized and engineered mining. Associated with these openings and workings is a number of ruins, which represent the mine buildings, chapels and residences of the inhabitants of the mining district during its past.

The vast bulk of the material which has been extracted from underground operations through the tunnels, shafts and winzes is scattered over the hillsides in waste dumps and beneath the foundations of the ruins and modern buildings. Historically, individual veins or deposits had separate owners and, in the case of some of the larger veins or deposits, had several owners along the strike length which resulted in a surfeit of adits and shafts and very inefficient operations.

The mines within the Velardeña mining district have been developed primarily by using open stope/ shrinkage and cut and fill underground mining methods. The ground conditions, which vary from

Table of Contents

good to poor, and the deposit geometries tend to favor both mining methods with development waste used for backfill.

ECU restarted operations at Velardeña in January 1998 and has been producing fairly continuously since that date.

Geological Setting

Regional Geology

The Velardeña district is located at the easternmost limit of the Sierra Madre Occidental, on the boundary between the Sierra Madre Oriental and the Mesa Central sub-provinces. Both of these terrains are underlain by Paleozoic and possibly Precambrian basement rocks. Most of Mexico's high-grade silver mines are located in the Mesa Central, near this contact.

The regional geology is characterized by a thick sequence of limestones and minor calcareous clastic sediments of Cretaceous age, intruded by Tertiary plutons of acidic to intermediate composition. During the Laramide Orogeny, the sediments were folded into symmetrical anticlines and synclines that were modified into a series of asymmetrical overturned folds by a later stage of compression.

A series of younger Tertiary stocks have intruded the older Cretaceous limestones over a distance of approximately 15 kilometers along a northeast to southwest trend.The various mineral deposits of the Velardeña mining district occur along the northeast-southwest axis and are spatially associated with the intrusions and their related alteration.

An important northwest-southeast fracture system is associated with these intrusions and in many cases, acts as the main focus of mineralization. These are deep, basement-penetrating boundary faults which served as magma conduits (Clark et al, 1988). A younger fracture system is the north-northeast to northeast trending faults which play an important role as they off-set the northwest trending mineralized veins. This is well demonstrated at ECU's Terneras mine where the northeast trending Tres Aguilas fault off-sets the mineralized northwest trending veins such as the Santa Juana veins.

Local Geology

The Velardeña Properties are underlain by a thick sequence of limestone that corresponds to rocks of the Aurora and Cuesta del Cura formations of Lower Cretaceous age. The Aurora limestone is generally medium to thick-bedded, dark grey to black and locally cherty. The Cuesta del Cura limestone is thin to medium bedded.

Several types of Tertiary intrusive rocks are present in the Velardeña district. The largest of these outcrops on the western flank of Sierra San Lorenzo and underlies a portion of ECU's Velardeña mines. It is referred to as the Terneras pluton and forms a northeast oriented, slightly elongated body, considered to represent a diorite or monzodiorite which outcrops over a distance of about 2.5 kilometers. The adjacent limestones have been altered by contact metamorphism (exoskarn) and locally the intrusive has been metamorphosed (endoskarn).

Property Geology and Mineralization

The following is a description of the individual geological characteristics and mineralizationfound on each of the properties comprising the Velardeña Properties.

Velardeña Property

The Aurora Formation hosts the Santa Juana, Terneras, San Juanes and San Mateo deposits on the Velardeña property. The limestones are intruded by a series of multiphase diorite or monzodiorite

Table of Contents

stocks (Terneras intrusion) and dikes of Tertiary age that outcrop over a strike length of approximately 2.5 kilometers.

Two main vein systems are present on the Velardeña property. The first is a northwest striking system as found in the Santa Juana deposit, while the second is east-west trending and is present in the Santa Juana, Terneras, San Juanes and San Mateo deposits.

In the Santa Juana deposit, two main sets of fracture cleavage are observed. The most economically significant is a steeply dipping northwest-trending cleavage that has acted as the main conduit for the mineralizing fluids in the Santa Juana deposit. This direction includes both linear and curved northwest vein sets. The second fracture cleavage trends 110? and is more widely spaced and not as clearly evident as the first set. This east-west vein system in the Santa Juana deposit is referred to as the Trans vein. These veins dip approximately 70? to 75? south and where they intersect the northwest-trending vein set, a chimney zone which can be up to 6 meters in width is often formed.

The Terneras, San Juanes and San Mateo veins all strike east-west and dip steeply north. The most prevalent of these is the Terneras vein, which was mined in the past over a strike length of 1,100 meters. All of these veins are observed to have extensive strike lengths and vertical continuity for hundreds of meters. The mineralogy of the east-west system is somewhat different in that they contain less arsenic than the northwest Santa Juana veins.

Mineralization in the deposits located on the Velardeña Properties primarily belongs to low- temperature calcite-quartz veins with associated lead, zinc, silver, gold and copper mineralization, typical of the polymetallic vein deposits of northern Mexico. The veins are usually thin, normally in the 0.2 meter to 0.5 meter range, but remarkably consistent along strike and down dip. Coxcomb and rhythmically banded textures are common.

Very little work has been carried out on the mineralogy of the veins and it varies considerably with the extent of oxidation. The sulfide parts of the veins consist primarily of galena and sphalerite with lesser amounts of zinc carbonates, chalcopyrite, tetrahedrite, electrum, freidbergite, arsenopyrite, pyrite and other sulfides. Historical and recent production in the district has been primarily from the oxide portions of the veins that extend to depths of several hundred metres, usually corresponding to the present day water table. The oxide portions of the veins are primarily reported to be composed of oxides, halides, carbonates and sulphosalts of primary mineralization. Oxidation is reported to be less extensive where veins transect the intrusive diorite or skarn. The zonation of the economic mineralization indicates increasing gold/silver and copper/lead ratios with depth.

Chicago Property

On the Chicago property, the oldest rocks outcropping are Cretaceous limestones of the Aurora Formation which are highly folded. These limestones are affected by the intrusion of the Tertiary dioritic stocks and dykes. The general geology of the Chicago property is very similar to the geology of the Velardeña property. The mineralization is similar to that encountered at the Santa Juana mine in terms of mineralogy, host rocks, geometry of the structures and continuity at depth and laterally.

The mineralization at the Chicago property is similar to that encountered at the Santa Juana mine in terms of mineralogy, host rocks, geometry of the structures and continuity at depth and laterally. The difference between the two is the strike, northwest dipping to the northeast instead of northeast dipping to the southeast.

San Diego Property

The vast majority of the San Diego property is underlain by massive beds of grey limestone from the Aurora Formation. These rocks were intruded by a younger Tertiary dioritic stock and porphyritic monzonite sills.

Table of Contents

The San Diego property hosts a well-developed pattern of high-grade silver-lead-zinc tabular veins that exhibit a persistent continuity both along strike and at depth. Together these veins represent the near-surface expression of a low-sulphidation epithermal system of mineralization that extends further at depth into the mezothermal environment. At least two main systems of veins are recognized, an east-west system that includes the Cantarranas, La Rata, Porvenir and SD veins as well as a northwest system that includes the Montanez, La Cruz, San José and Trovador veins. The other veins on the property, the northeast trending El Jal vein and east-northeast striking Canta-Splay vein, are recognized as subsidiary structures.

In addition to the veins structures, the present resource estimate includes mineralization outlined in the newly discovered broad zones of mineralization, identified during recent drill programs. These are stockwork zones consisting of a mix of narrow sulfide +/- calcite stringers (1 to 2 centimeters) and veins (up to 30 centimeters) as well as carbonate- replacement sulfide bands (or irregular patches) developed around the veins and stringers which in-fill pre-existing fractures.

Exploration

Exploration of the Velardeña Properties since January 2008 has consisted mostly of underground work and is largely related to further mine development. This work includes using a small drill to test new areas close to the existing underground workings and various types of underground development focused on discovering new veins. Since 2008, ECU has drilled approximately 140 holes totalling approximately 6,200 meters. ECU's underground exploration development activities consisted of approximately 3,400 meters of drifting along the structures or veins, 400 meters of ramps to access new areas, 900 meters of cross-cuts to reach specific zones on various levels and 1,850 meters of raises in veins and structures to confirm their vertical continuity. In addition, surface geological sampling and mapping has been completed in several specific sections of the Velardeña Properties and certain other properties which were being evaluated. ECU has recently commenced deeper drilling at Velardeña, focused on further defining a sulfide deposit identified in previous drilling that encountered an intercept of massive sulfide mineralization. ECU has also commenced detailed geological sampling and mapping on the Nazas property.

Drilling and Sampling Method and Approach

Surface and Underground Chip Sampling

Underground chip samples are taken at drift faces, cross-cuts and stopes, wall and/or backs according to the following criteria:

•: The samples are taken by chiselling out a 5 to 7 cm deep cut into the material.
•: The minimum and maximum sample widths are 0.10 and 2.5 meters, respectively.
•: The sample's weight is usually between 2 and 5 kg, and the sample contains a minimum of 10 rock pieces (<20 cm in size) as well as fine material.
•: Sampling is carried out perpendicular to the vein and the true width of the structure is recorded.
•: Stope and face samples are collected at 3 meter intervals across the width of the drift or stope, sampling wall rock and vein material separately. When dictated by geological features, samples are taken at closer intervals.
•: Sampling along crosscuts is carried out continuously.
•: The location of the samples is determined by means of survey stations, and direction is recorded at the time of sampling.

Surface sampling follows the same criteria listed above, except for the spacing, which is dictated by the condition of the outcrop.

Drill Core Sampling Protocol

Diamond drill core samples are taken, according to the following criteria:

•: Drill core sampling is carried out on core which has been split using a manual rock splitting device.
•: Samples are taken from core sections with visible evidence of mineralization and from 1.5 to 2.0 meters of surrounding wall rock.
•: Wall rock between two veins is sampled when the distance is less than 6 meters.
•: The information recorded in the drill logs for each sample includes depth, length, core angle, and rock/ore type.
•: Short range drill holes across the Santa Juana vein packages of the Mineralized Corridor are sampled completely.
•: Mineralized sample intervals for either the NQ or BQ size core have a minimum core length of 20 cm and a maximum length of 1 meter. For areas sampled outside of the mineralization the maximum sample length for the NQ core is 1.20 meters and for BQ core the maximum sample length is 1.50 meters. In general, the maximum sample length is 1.0 meters except for those areas in which 2 veins can be joined together in which case the maximum sample length is 2 meters.
•: In general the core recovery is 60% in the oxide mineralization while it is 90 to 97% in the sulfide mineralization as well as the remaining portions of the BQ and NQ core. For the smaller Bazooka drill core (IEW) the overall recovery ranges from 30% to 40% and is generally used to identify the apparent width of the zone. Bazooka drilling is undertaken from the development headings in order to identify the width of a zone where the hangingwall is not visible or where a secondary mineralized system is suspected as in the case of the sheeted veins.

The drill core sampling procedures practiced by ECU are among the commonly practiced procedures used throughout the mineral industry. Along with in-house standards, blanks, and duplicates included in the sample stream, routine check assays are conducted on the samples by a second laboratory as well.

January 2009 Mineral Resource Estimate

Micon has reviewed the resource estimate for the Velardeña Properties prepared by ECU's geological staff as at November 15, 2008. At this time, ECU is still using the traditional polygonal method based on the use of a long section to estimate the resources.

Tonnage and grade for all resource blocks are estimated by ECU on longitudinal sections for each of the veins and/or vein packages combined with width and density information for each cross-section for the measured and indicated resources and average widths and densities of all intercepts for the inferred. The block limits are defined by mined out areas, excavated historical mining levels or workings, mineralization style (broad zones versus narrow veins), faults, geological contacts and property limits. Assays are capped and diluted as previously described.

The geological continuity of each zone was determined on 20 meter cross-sections based on stratigraphy, mineralization and structure using underground development and sampling plus diamond drill holes and surface information when applicable.

For calculation of the block areas for all blocks that did not changed since the last report, the surface area of each block was measured on the long section (orientated vertically but parallel to the strike of the vein) using MineSite and then this figure was multiplied by the measured horizontal width

of the vein to obtain the actual block volume. Block tonnage is then estimated by multiplying the volume figure by the applicable specific gravity factors, previously described. For all new blocks, the Pro-Mine software was used to divide the areas in polygons and give tonnages and diluted grades for each polygon.

The resource estimates are based on a net smelter return value cut-off of $45/tonne for the individual veins and $25/tonne for the vein packages.

The following criteria were used to classify the estimated resources according to the current CIM definitions:

1) Measured Resources: Those blocks or that portion of the mineralization between mine levels, 10 meters on each side of the stopes laterally and 25 to 50 meters below the lowest drifts depending on proven vertical continuity.

2) Indicated Resources: Those blocks or mineralized portions of the deposit defined to a vertical depth of 25 meters below measured resources and 10 meters laterally adjacent to measured resources or an historic mining area with no information.

3) Inferred Resources: Those blocks or mineralized portions of the deposit defined by surface sampling and/or drill hole samples. In most cases where the extent of the mineralized zone is unknown, the extent of the inferred resources has been estimated at a maximum of 100 meters. The depth of the inferred resources for those zones which have been explored by drill holes has been set at 50 meters below the lowest mineralized drill intersection.

Table of Contents

The final mineral resource estimate does not include areas within the measured or indicated blocks where previous mining was conducted.

The resulting mineral resource statement for the Velardeña Properties is effective as of November 15, 2008. The tonnages and grades for the measured, indicated and inferred mineral resource estimates are summarized in the following table. The figures in the table have been rounded to reflect that the mineral resource estimate is an approximation.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. There are no mineral reserves presently identified on the Velardeña Properties.

The stated resources are not materially affected by any known environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant issues. There are no known mining, metallurgical, infrastructure or other factors that materially affect this mineral resource estimate at this time.

The mineral resource estimate conducted by ECU is compliant with the current CIM standards and definitions required by NI 43-101 and is, therefore, reportable as a mineral resource by ECU.

Mining and Milling Results

Since January 2008, ECU has mined sulfide and oxide mineralized material from the Velardeña project, with most production from the Santa Juana mine, and produced zinc, lead and pyrite concentrates through its sulfide mill. During this period, ECU has also produced pyrite concentrates from processed tailings and has custom milled ore from a nearby mine. Since early 2009, ECU has also operated an oxide mill producing doré bars.

Management's Discussion and Analysis of Financial Condition and Results of Operations

All dollar amounts presented in this section are presented in Canadian dollars.

Liquidity and Capital Resources

At March 31, 2011, ECU had a working capital deficit of $12,677,443 compared to $11,747,189 at December 31, 2010. The change of $930,254 reflects mainly an increase of $1,548,977 in the current portion of long-term debt. Principal repayment on ECU's long-term debt commences July 2011.

During the quarter ECU used cash of $863,182 in operations compared to $3,104,977 in the same period in the prior year. The decrease of $2,241,795 reflects mainly an increase in non cash working capital items.

ECU is focused on improving the cash flows that it generates from its mining and milling operations. It is conducting underground exploration in conjunction with mining operations, and has recommenced exploration. ECU has not completed an economic study related to the treatment of its oxide resource through the plant and therefore cannot provide any assurances that its operation will be economic.

ECU had no significant commitments to capital spending as at period end.

Changes to Accounting Policies

Effective for the first quarter of 2011, the Company has prepared its financial statements in accordance with IFRS. The comparative financial information for the 2010 financial year in this Management Discussion and Analysis has also been restated to conform to IFRS. This Management Discussion and Analysis should be read in conjunction with Note 23 "Transition to IFRS" in ECU's March 31, 2011 consolidated interim financial statements attached as Annex D to this proxy statement.

The primary adjustment as a result of the transition from Canadian GAAP to IFRS in the statement of financial position relates to foreign exchange translation. Under Canadian GAAP, ECU used the temporal method in translating foreign operations and non-monetary assets and liabilities in foreign currency to the presentation currency. An adjustment was required to record the impact of translating mining property costs and property plant and equipment at the closing rates on consolidation rather than the historic rates and removing exchange differences on the consolidation of foreign operations from profit or loss and including in equity.

Coincident with the IFRS disclosure requirement for finance costs paid and income tax paid to be presented as separate items in the statement of cash flows, ECU has determined to exclude finance costs in the calculation of operating cash flows before movements in working capital, and to include it in cash flow from financing activities.

Results of Operations for the Three Months Ended March 31, 2011 Compared to the Three Months Ended March 31, 2010

Loss

The loss for the first quarter 2011 was $2,081,960 versus a loss of $1,915,436 for the same period in 2010.

Expenses

Expenses totaled $773,662 in the first quarter of 2011 a decrease of $363,030 over the same quarter in 2010. The foreign exchange account moved from a gain of $802,013 in 2010 to a gain of $574,667 in the current period mainly because of the effect of the volatility of the US dollar on ECU's

long-term debt. No employee stock options were issued in the first quarter of 2011 and stock-based compensation decreased $347,142.

Finance income and costs

Finance costs increased by $526,810 from $782,766 in Q1 2010 to $1,309,576 in Q1 2011. The first quarter 2011 includes $483,400 in costs related to the restructuring of ECU's term loan.

Assets

Total assets were $74,490,097 as at March 31, 2011 compared to $74,196,337 as at December 31, 2010. Cash and cash equivalents increased $875,108 from $344,826 at December 31, 2010 to $1,219,934 at March 31, 2011.

Liabilities

Liabilities totaled $26,737,570 as at March 31, 2011 compared to $27,000,284 as at December 31, 2010 a decrease of $262,714.

Shareholders' equity

Shareholders' equity totaled $47,752,527 as at March 31, 2011 compared with a balance of $47,196,053 at the end of 2010. The change reflects the loss for the period of $2,081,960 reduced by the $860,457 gain on translation of ECU's Mexican subsidiaries. ECU issued shares on the exercise of options and warrants for net proceeds of $1,777,977.

As at March 31, 2011 ECU had 310,726,233 shares outstanding, 13,235,000 options outstanding granted under its stock purchase plan at a weighted average exercise price of $2.00 each, and 48,170,926 warrants outstanding at a weighted average exercise price of $0.93 each.

Cash used in operating activities

Cash used in operations for the quarter ended March 31, 2011 was $863,182 compared to $3,104,977 in the prior year. The decrease of $2,241,795 arose mainly from a net increase in non-cash working capital items.

Cash used in investing activities

In the first quarter of 2011, net cash used for mining property costs was $4,383,608 compared to $3,833,904 in the prior year. The increase of $549,704 reflects increased activity levels in mining and milling operations. In the quarter revenue from the sale of doré bars and concentrates amounting to $5,996,092 has been credited against the mining costs compared with $3,186,266 in Q1 of 2010.

Cash from financing activities

During the quarter ECU did not undertake any new financings.

Cash and cash equivalents

As of March 31, 2011, ECU held cash and cash equivalents in the amount of $1,219,934 compared to $344,826 at year-end in 2010.

Table of Contents

Results of Operation for the Year Ended December 31, 2010 Compared to the Year Ended December 31, 2009

Loss

ECU's loss for the year was $6,854,967 or $0.022 per share, compared to a loss of $8,417,937 or $0.030 per share in 2009.

Expenses

Expenses totaled $6,854,967 for the year, compared to $8,417,937 in 2009, representing a decrease of $1,562,970. During the year, ECU sold of a portion of its gold pyrite material-in-process inventory which gave rise to a reversal of previous inventory cost write-offs and resulted in a gain in the amount of $2,045,613 and that contributed to the decrease in expenses. Stock-based compensation made up $715,540 of the change. ECU recorded a foreign exchange gain of $1,314,059 in 2010 compared to a gain of $3,520,810 in the prior year. These gains result mainly from the positive effect of the weakening US dollar on ECU's long-term debt. The decrease in gain of $2,206,751 offset the above noted decreases in expenses.

Depreciation of Property, Plant and Equipment—The amounts related to depreciation remained relatively unchanged at $214,707, compared to $182,679 in 2009.

Assets

The total assets of ECU decreased $5,449,478 from $92,134,278 as of December 31, 2009 to $86,684,800 at the end of 2010. This change results from an increase in revenues, which are offset against mining property costs, together with ECU's decision not seek financing during year.

Liabilities

The liabilities were relatively unchanged at $27,000,284 at December 31, 2010 compared to $27,394,645 as of December 31, 2009. Reductions in long-term debt were largely offset by increases in customer advances.

Shareholders' equity

Shareholders' equity totaled $59,684,516 as of December 31, 2010, compared with $64,739,633 at the end of 2009, representing a decrease of $5,055,117.

The decrease results mainly from the $6,854,967 loss generated by administrative, financing and other non-mining property costs. Other items affecting shareholders' equity are an increase of $840,000 resulting from the exercising of stock options and warrants, and an increase in contributed surplus of $959,850 reflecting the calculated value of the vesting portion of stock-based compensation.

At year-end 2010, ECU had 308,236,733 shares outstanding, 15,365,000 options outstanding under its stock option plan and 50,310,426 share purchase warrants outstanding.

Cash flow used in operations

Cash used in operations was relatively unchanged at $6,396,534 for 2010 compared to $5,853,171 in 2009.

Cash flow used in investments

For the year 2010, net cash used for mining property costs, being operating and development costs less revenues, was negative ($1,709,790) resulting in the net generation of cash. This compares to a use of cash of $3,977,919 in the prior year. The increase in cash generated of $5,687,709 reflects the effect

of improved mining and milling operations as well as sales of pyrite stockpiles amounting to $3,191,377. Revenue from the sale of doré bars, concentrates and pyrite stockpiles totaled $19,345,686 and has been credited against the mining costs.

Costs for the acquisition of property, plant and equipment were $958,378 in 2010 compared to $11,267,378 in the prior year. The 2009 figure consisted principally of costs related to the acquisition and commissioning of the 500 tonne-per-day gold and silver cyanide leach plant. In 2010 ECU paid $2,487,037 for the acquisition of mineral property concessions including payments of $2,331,600 under an installment contract.

These figures reflect ECU's ongoing commitment to the growth of its mineral resources and the execution of ECU`s plan to create an internal source of cash flows.

Cash flow from financing activities

In 2010, ECU did not undertake any financings. It received $240,000 from the exercise of stock options under the employee stock option plan and $600,000 from the exercise of warrants.

In 2009, ECU generated $31,163,086 from financing activities. The financings consisted of a combination of a prospectus offering, private placements and the exercise of stock options. Cash of $783,166 was used for the repayment of promissory notes payable and $918,161 was sourced through an increase in the term loan.

Cash and cash equivalents

As of December 31, 2010, ECU held cash and cash equivalents in the amount of $344,826 compared to $7,647,023 at year-end in 2009.

Results of Operations for the Year Ended December 31, 2009 Compared to the Year Ended December 31, 2008

Expenses totaled $8,417,937 for 2009, compared to $18,043,280 in 2008, representing a decrease of $9,625,343. The foreign exchange account moved from a loss of $3,525,156 in 2008 to a gain of $3,520,810 in 2009, mainly because of the positive effect of the weakening US dollar on ECU's long-term debt, making up $7,045,966 of that change. Stock-based compensation made up $2,350,511 of the change. During 2008, we recorded a provision for loan loss of $1,242,934 due to the fact that the decline in the trading price of ECU's common shares had eroded the value of the employee options that were taken as security for such loans. The amounts related to depreciation remained relatively unchanged at $182,679, compared to $148,054 in 2008.

Assets

The total assets of ECU increased from $63,596,834 as of December 31, 2008 to $92,134,278 at the end of 2009. This increase reflected ECU's continued investment in mining property exploration and development and in the purchase of property, plant and equipment, most notably the acquisition and commissioning of the Plant.

Liabilities

The liabilities decreased to $27,394,645 as of December 31, 2009, from $30,313,558 in 2008. The change was mainly attributable to the financings undertaken during the year which converted to equity

Table of Contents

the outstanding balance in convertible debentures and certain notes payable, offset by increases that result from the changes in exchange rates on ECU's US dollar denominated debt.

Shareholders' equity

Shareholders' equity totaled $64,739,633 as of December 31, 2009, compared with $33,283,276 at the end of 2008, representing an increase of $31,456,357.

The increase in shareholders' equity results mainly from financing activities including debt conversion, option exercises and equity raises, which increased share capital, special warrants, equity component of convertible debentures, contributed surplus, and deficit by a combined net total of $37,887,494.

Other items affecting shareholders' equity were an increase in share capital of $375,000 as a result of the issuance of shares in connection with the purchase of capital assets, an increase in contributed surplus of $1,611,800 reflecting the calculated value of the vesting portion of stock-based compensation, and an increase in the deficit for the loss for the year of $8,417,937.

At year-end 2009, ECU had 290,340,733 shares outstanding, 15,740,000 options outstanding under its stock option plan and 42,487,426 share purchase warrants outstanding.

Cash flow used in operations

Cash used in operations for 2009 was $5,853,171, compared to $6,236,808 in 2008. A decrease in expenses year over year was largely offset by a change in accounts payable and customer advances.

Cash flow used in investments

ECU made cash investments totaling $10,555,086 in the exploration, development and operation of mining properties compared to $11,197,499 in the prior year. After the commissioning of the Plant, ECU began selling doré bars and that together with sales from concentrates resulted in total sales of $6,577,167 in 2009 which reduces ECU's overall cash investment. In 2009 ECU paid $3,428,880 for the acquisition of mineral property concessions including payments of $2,331,600 under an installment contract. $11,267,378 was paid for the purchase of property, plant and equipment being principally related to the acquisition and commissioning of the plant. These figures reflected ECU's ongoing commitment to the growth of our mineral resources and the execution of its plan to create an internal source of cash flows.

Cash flow from operating activities

During 2009, ECU generated $31,298,081 from financing activities. The financings consisted of a combination of a prospectus offering, private placements and the exercise of stock options. Cash of $783,166 was used for the repayment of promissory notes payable and $918,161 was sourced through an increase in the term loan.

In the prior year, ECU generated $10,613,660 from financing activities. The financings consisted of US$3,000,000 under the terms of a long-term debt facility, $6,000,000 in proceeds from the sale of convertible debentures, $75,000 in loan proceeds in connection with expenditures made for leasehold improvements, and $870,000 and US$535,100 in demand loans.

Cash and cash equivalents

As of December 31, 2009, ECU held cash and cash equivalents in the amount of $7,647,023, compared to $538,215 at year-end in 2008.

(1): ECU has made arrangements with the customer of its doré bars to provide financing in the form of advances prior to product delivery. The advances are denominated in U.S. dollars and interest is charged at the rate of 18% per annum on outstanding balances. The amount shown in the table has been converted to Canadian dollars at the exchange rate as of December 31, 2010.
(2): The operating lease obligations are related to the lease of our corporate headquarters office in Toronto, Ontario, which expires in February 2013, and the lease of our office on Torreón, Mexico, which expires in October 2011.
(3): As of December 31, 2010, ECU owed Cdn$16.5 million under its term loan facility, the terms of which called for principal repayments in equal monthly installments for 12 months commencing January 31, 2011. During 2011, ECU completed a restructuring of its term loan facility. Principal payments under the amended facility are payable in thirty equal monthly payments commencing July 31, 2011 and ending December 31, 2013. The table above reflects the payment terms of the term loan facility as restructured.
(4): In 2009, ECU entered into contracts which terminated a legal action related to title on the Velardeña property. Under the terms of the contracts, ECU agreed to pay a total of US$6,000,000 in a series of 6 payments of US$1,000,000, commencing May 19, 2009 and running semi-annually thereafter ending November 17, 2011, without interest. The amount shown in the table has been converted to Canadian dollars at the exchange rate as of December 31, 2010.

Off-Balance Sheet Arrangements

ECU does not have any off-balance sheet arrangements.

Changes and Disagreements with Accountants

ECU has had no change of accountants nor disagreements with accountants on any manner of accounting principles or practices or financial statement disclosure during its two most recent fiscal years.

Legal Proceedings

ECU was a party to a lawsuit, before the courts in Mexico, regarding the title to four of the mineral concessions comprising the Velardeña property, in respect of which a third party had alleged to have an undivided 30% ownership interest. The latest decision by the court, awarding the 30% interest to the plaintiff, was in appeal by ECU. On May 11, 2009, ECU entered into contracts which terminated

Table of Contents

the legal actions and settled the title matter. Under the terms of the contracts, ECU agreed to pay a total of US$6,000,000 in a series of 6 payments of US$1,000,000, commencing May 19, 2009 and running semi-annually thereafter ending November 17, 2011, without interest.

On June 24, 2009, ECU received a Notice of Arbitration (the "Notice") from its San Diego Property joint venture partner, Golden Tag Resources Ltd., wherein the latter sought to refer certain matters pertaining to the operation of the joint venture to arbitration for resolution. During the year, the arbitration hearing held pursuant to the Notice was completed and on September 20, 2010 the Arbitration Panel rendered their conclusion in the matter. ECU finds the award of the arbitration panel ("Arbitration Award") to be fair and has settled the matter with Golden Tag. The conclusions reached in the Arbitration Award have resulted in an increase in the Velardeña mining property costs of $61,171 related to cost of material from the joint venture property processed in ECU's plant.

Quantitative and Qualitative Disclosures about Market Risk

Metal Price Risk

It is anticipated that the majority of ECU's revenue will be generated from the sale of gold, silver, lead and zinc. A reduction in the market price of gold, silver, lead or zinc may prevent ECU's properties from being economically mined or result in the write-off of assets whose value is impaired as a result of low metals prices. ECU's sales are directly dependent on metal prices that have historically been subject to wide fluctuations, and are affected by numerous factors beyond the control of ECU, such as interest rates, inflation, currency values, speculative activities, global supply of, and demand for, precious and base metals, metal stock levels maintained by producers and others and international and political conditions. The effect of these factors on the price of base and precious metals cannot be accurately predicted and there can be no assurance that the market price of these metals will remain at current levels or that such prices will improve. A decrease in the market price of gold, silver, lead or zinc could affect the profitability of ECU's properties and ECU's ability to finance exploration and development, which would have a material adverse effect on ECU's financial condition and results of operations.

Exchange rate risk

ECU reports its financial statements in Canadian dollars and operates mainly in Mexico. As a consequence, the financial results of ECU's operations, as reported in Canadian dollars, are subject to changes in the value of the Canadian dollar relative to the Mexican peso. The majority of ECU's revenue is generated from the sale of gold, silver, lead and zinc, generally denominated in US dollars, and ECU's operating costs are denominated in US dollars and Mexican pesos. ECU has debt obligations that are denominated in US dollars. Fluctuations in the exchange rate of the American and Mexican currencies in relation to the Canadian dollar could have a significant adverse effect on ECU's costs of development, earnings, halt or delay development of new projects and reduce funds available for further mineral exploration. ECU's currency risk is somewhat mitigated through the offsetting streams of metal sales in US dollars and interest and other expenses in US dollars.

Interest Rate Risk

ECU is exposed to fluctuations in rates of interest. The terms of the long term debt facilities with its principal lender provide for interest to be calculated at the greater of; 12% and 1-month London Interbank Offered Rate ("LIBOR") plus 6%. Should the LIBOR rate increase to 6%, then each further 1% increase would result in an increase in annual interest charges of $166,185 based on principal outstanding at June 30, 2011.

PARTICULARS OF MATTERS TO BE ACTED UPON AT THE GOLDEN MEETING

Proposal No. 1—The Share Issuance Proposal

Purpose and Effect of Proposed Issuance of Stock

Golden is seeking your approval of the proposed issuance of approximately 18.9 million shares of Golden common stock to ECU's stockholders in connection with the Transaction.

In connection with the Transaction, ECU shareholders will receive 0.05 shares of Golden common stock and Cdn$0.000394 in cash for each share of ECU common stock held immediately prior to the consummation of the Transaction. As of June 24, 2011, the date of the Arrangement Agreement, ECU had 317,081,333 shares outstanding and an additional 3,000,000 shares were issued by ECU after that date as payment for the prior exercise of an option to purchase an exploration property. Assuming that no ECU options or warrants are exercised after June 24, 2011, ECU would have 320,081,333 shares outstanding, and Golden would issue approximately 16,004,066 shares to ECU shareholders at closing. The exact number of shares issued at closing will be subject to adjustment for rounding. In addition, an estimated 167,068 shares of Golden common stock would be issued, in the aggregate, to Mr. Roy and Mr. Altmann in lieu of their cash change of control payments. The exact number of shares to be issued will be determined on the closing date based on the five-day volume weighted average price of Golden's common stock on the NYSE Amex immediately prior to such date. Also, as further discussed below, assuming that none of the ECU options or warrants are exercised prior to the closing date, 661,750 Golden shares would be issuable upon exercise of Golden Replacement Options and 2,218,291 Golden shares would be issuable upon exercise of Golden Replacement Warrants. Therefore, a total of approximately 19,051,175 may be issuable to ECU shareholders (or holders of ECU options or warrants upon exercise of such securities) as a result of Transaction.

The proposed issuance of Golden common stock will result in dilution in the percentage ownership interest of Golden's existing stockholders. The exact amount of such dilution cannot be determined until the time of issuance; however, if Golden had issued, as of March 31, 2011, the estimated number of shares of Golden's common stock contemplated by the Transaction of approximately 16.0 million shares, which excludes up to approximately 2.9 million new shares that will be issuable upon the exercise of existing ECU options and warrants and approximately 167,000 shares to be issued, in the aggregate, to Mr. Roy and Mr. Altmann in satisfaction of change of control payments, then based upon approximately 15.3 million shares of Golden's common stock outstanding as of that date, a book value per Golden share as of March 31, 2011 of $7.64, and a book value of $6.21 in the assets acquired from ECU, the outstanding shares of Golden's common stock outstanding would have increased by approximately 104%, and the book value per share of Golden's common stock would have increased from $7.64 to $13.85. If Golden issues all 19.1 million shares issuable pursuant to the Transaction, including approximately 167,000 shares to be issued in satisfaction of certin ECU change of control bonus payments, then based on 15.3 million shares of Golden stock outstanding as of June 24, 2011, the dilution to existing stockholders would be approximately 125%.

Requirement for Stockholder Approval

Golden's listing application with each of the NYSE Amex and the TSX require stockholder approval for the issuance of Golden common stock (including if Golden common stock is issuable upon the exercise of convertible securities) that represents in the aggregate more than 20% and 25%, respectively, of the issued and outstanding shares of Golden common stock.

As of June 24, 2011, 15,302,675 shares of Golden common stock were issued and outstanding. Upon the consummation of the Transaction, ECU's securityholders will acquire up to approximately 18,884,107 million shares of Golden common stock, including shares of common stock issuable upon exercise of Golden Replacement Options and Golden Replacement Warrants. Since this represents more than 25% of the shares of Golden common stock issued and outstanding prior to the

Table of Contents

consummation of the Transaction, stockholder approval is required pursuant to NYSE Amex and TSX listing rules.

Required Vote and Board of Directors' Recommendation

YOUR BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE
"FOR"
PROPOSAL 1—THE SHARE ISSUANCE PROPOSAL

Table of Contents

Proposal No. 2—The Charter Amendment Proposal

General

Golden's board of directors has unanimously adopted a resolution approving, declaring advisable and recommending to stockholders for their approval an amendment to Article IV of Golden's Amended and Restated Certificate of Incorporation increasing the total number of shares of its authorized common stock from 50,000,000 shares to 100,000,000 shares.

The form of the proposed amendment to Golden's Amended and Restated Certificate of Incorporation is attached as Annex G to this proxy statement. The proposed amendment will become effective upon the filing of the amendment with the Delaware Secretary of State, which Golden plans to do immediately following the consummation of the closing of the Transaction.

Approval of the Charter Amendment Proposal is not required to approve the consummation of the Transaction. If the Share Issuance Proposal is not approved, or if the Transaction is not consummated for any reason, we will not proceed with the amendment to our Amended and Restated Certificate of Incorporation, regardless of whether the Charter Amendment Proposal is approved.

Reasons for the Proposed Amendment

Golden's board of directors recommends approval of the proposed amendment so that it will have additional authorized but unissued and unreserved shares to permit the pursuit and effectuation of corporate transactions requiring the issuance of common stock in the future. Those transactions may include:

•: the issuance of common stock in connection with the growth and expansion of Golden's business, including acquisition of mining properties or other companies engaged in the mining business;
•: the issuance of common stock or securities convertible into common stock in connection with financing and recapitalization transactions;
•: the future authorization of additional shares of common stock for issuance under Golden's executive compensation program and the Incentive Plan; and
•: the issuance of common stock in connection with other corporate transactions that implement proper business purposes determined by the board of directors to be in the best interests of Golden and its stockholders.

As explained below, approximately 12.9 million shares of unissued, unreserved common stock will remain available for future issuance following the Transaction. The Golden board believes that additional authorized shares should be available in the future in order to permit Golden to pursue the various transactions described above and to provide for its growth and financial stability. Many of the above transactions arise under circumstances requiring prompt action and do not allow the necessary time to seek stockholder approval to authorize additional shares. The board believes that it is very important for it to have the flexibility to be able to act promptly in the best interests of Golden and its stockholders when circumstances such as those described above arise. For example, one of our largest stockholders, The Sentient Group, has expressed an interest in investing further capital in Golden following the Transaction in order to retain its current proportionate interest. The additional shares authorized pursuant to this proposal would permit the Board to undertake such transactions in the best interests of stockholders.

Golden may pursue the acquisition from time to time of other mining companies, mining properties or interests in mining properties in the future. In the event the proposed increase in authorized shares of common stock is approved by stockholders, such future acquisitions may be effected for a consideration that includes the issuance of shares of Golden common stock, or other

Table of Contents

securities convertible into Golden common stock, in partial or full payment of the purchase price. Golden anticipates that the terms of any acquisitions in which it would issue shares will be determined through direct negotiations with the securities holders or controlling persons of the entities or properties being acquired. Factors taken into account in determining the terms may include cash flow, reserves and mineralized material, earnings power, quality of management, properties, market location and position, and growth potential. Other than with respect to the Transaction, Golden has not entered into any agreements nor made any decisions with respect to the issuance of any shares in connection with any future acquisitions. If Golden determines to issue shares of common stock in connection with future acquisitions, Golden will not seek stockholder approval of such issuance unless required as discussed below under "Future Stockholder Approval of Common Stock Issuances." The issuance of any such shares of common stock will have no effect on the rights of existing stockholders.

Risks of Non-Approval

If the Share Issuance Proposal is approved and the Transaction is consummated, but the Charter Amendment Proposal is not approved, the ability of Golden to raise additional capital or undertake strategic acquisitions may be significantly constrained. As noted below under the heading "Currently Issued or Reserved Common Stock," following the consummation of the Transaction, a total of approximately 37.1 million shares of Golden common stock will be issued or reserved for issuance. This would leave Golden with only approximately 12.9 million shares of unissued, unreserved common stock, representing approximately 25.7% of the currently authorized shares of common stock. Many transactions which may result in the issuance of Golden common stock could require prompt action and may not allow the necessary time to seek stockholder approval to authorize additional shares. Without sufficient authorized capital available, Golden may not be able to undertake such transactions.

Currently Issued or Reserved Common Stock

The table below sets forth the estimated number of shares of Golden common stock that will have been issued or reserved for future issuance, assuming the Transaction is consummated:

Golden Minerals
Common Shares Issued or Reserved for Issuance(1)


Outstanding Common Stock Prior to Transaction			15,302,675
Common Stock Issued to ECU shareholders			16,004,066
Shares Issued in Lieu of ECU Change of Control Obligations			167,068

Total Outstanding Common Stock			31,473,809

Shares Issuable Upon Exercise of Golden Options			136,810
Shares Issuable Upon Exercise of Golden Restricted Stock Units			60,910
Shares Issuable Upon Exercise of Golden Replacement Options			661,750
Shares Issuable Upon Exercise of Golden Replacement Warrants			2,218,292
Shares Reserved for Issuance under Golden Incentive Plan(2)			2,587,509

Total Shares Reserved for Issuance			5,665,271

Total Shares of Common Stock Issued or Reserved for Issuance			37,139,080

(1): Amounts shown are as of June 24, 2011, the date the Arrangement Agreement was executed, and assume that no ECU options or warrants or Golden options have been exercised subsequent to that date.
(2): The pool of shares available under our 2009 Equity Incentive Plan is equal to 10% of our outstanding shares of common stock, plus shares issuable upon exercise of outstanding

100

Table of Contents

warrants and other convertible securities, other than awards under the 2009 Equity Incentive Plan.

Future Stockholder Approval of Common Stock Issuances

The additional shares of common stock sought by the proposed amendment would be available for future issuance without future action by stockholders, unless such action would be required by applicable law or the rules of the NYSE Amex or TSX. Generally, NYSE Amex and TSX rules require stockholder approval of proposed issuances of additional shares that would result in an increase of 20% or more in the case of NYSE Amex, and an increase of more than 25% in the case of TSX, in the total number of shares of common stock outstanding before any such proposed issuance. The NYSE Amex stockholder approval requirement is subject to exemptions for certain public and private offerings for cash and an exception where the delay in securing stockholder approval would seriously jeopardize Golden's financial viability and where Golden's reliance on such exception is expressly approved by the audit committee of its board of directors. Stockholder approval also is required under NYSE Amex rules prior to an issuance of common stock that would result in a change of control of Golden. Furthermore, NYSE Amex rules require stockholder approval under certain circumstances with respect to certain stock option or purchase plans and with respect to proposed issuances of common stock, or of securities convertible into or exercisable for common stock, to directors, officers or substantial stockholders of Golden or its affiliates.

Potential for Anti-Takeover Effect

Although the board of directors' purpose for seeking an increase in the number of authorized shares of our common stock is not intended to discourage or prevent takeover attempts, it should be noted that authorized but unissued shares of common stock, if issued, could be used by incumbent directors to make more difficult and thereby discourage an attempt to acquire control of Golden even though its stockholders might deem such an acquisition desirable. For example, the shares could be privately placed with purchasers who might support the board of directors in opposing a hostile take-over bid. The issuance of the new shares could also be used to dilute the stock ownership and voting power of a third party seeking to remove directors, replace incumbent directors, accomplish certain business transactions or alter or amend provisions of Golden's Restated and Amended Certificate of Incorporation. To the extent that it would impede any such attempts, the issuance of additional shares of common stock following effectiveness of the proposed amendment to Golden's Amended and Restated Certificate of Incorporation could potentially serve to perpetuate the existing management.

Required Vote and Board of Directors' Recommendation

In order for the amendment to become effective, the Charter Amendment Proposal must be approved by the holders of a majority of the shares of Golden common stock outstanding and entitled to vote thereon.

(including under Sections 7.2.1 and 7.2.2), the board of directors of such Party may make an ECU Board Change in Recommendation or a Golden Board Change in Recommendation (collectively, an "Adverse Recommendation Change"), as applicable, (i) following receipt of an Acquisition Proposal that it determines to be a Superior Proposal or (ii) solely in response to any material event, development, circumstance, occurrence or change in circumstances or facts (including any change in probability or magnitude of circumstances) not related to an Acquisition Proposal that was not known to the board of directors of such Party on the date hereof (or if known, the magnitude or material consequences of which were not known to the board of directors of the Party as of the date hereof) (an "Intervening Event"), in each case if it determines in good faith, after consultation with its legal advisors, that the failure to take such action would be inconsistent with its fiduciary duties under applicable law.

In addition, nothing contained herein shall prevent either Party or its board of directors from (i) complying with Rule 14d-9 or 14e-2(a) under the U.S. Exchange Act or any comparable applicable Law, or making any similar communication to stockholders in connection with any amendment to the terms of a tender offer, exchange offer or takeover bid, so long as any action taken or statement made to so comply is consistent with the requirements of this Article 7, (ii) disclosing factual information regarding the business, financial condition or results of operations of such Party or the fact that an Acquisition Proposal has been made, the identity of the party making such proposal or the material terms of such proposal, to the extent such Party in good faith determines that such information, facts, identity or terms is required to be disclosed under applicable Law or that failure to make such disclosure would be inconsistent with its fiduciary duties under applicable Law or (iii) making any statement or disclosure to such Party's securityholders required by applicable Law; provided that any such action taken or statement or disclosure made that relates to an Acquisition Proposal shall be deemed to be an Adverse Recommendation Change unless the board of directors of such Party reaffirms the recommendation contemplated by Section 2.5(b) or Section 2.11(b), as applicable, in such statement or disclosure or in connection with such action (except that a mere "stop, look and listen" disclosure in compliance with Rule 14d-9(f) of the U.S. Exchange Act or any comparable applicable Law, shall not constitute an Adverse Recommendation Change).

7.2.4 Each Party shall promptly (and in any event within 24 hours of receipt by the Party, any subsidiary or any of its Representatives) notify the other Party, at first orally and then in writing, of any offer, proposal, expression of interest, or inquiry (oral or in writing) relating to or constituting, or which would reasonably be expected to lead to, an Acquisition Proposal, all requests for discussions or negotiations relating to an Acquisition Proposal and all requests for non-public information relating to the Party or any of its subsidiaries or for access to the properties, books or records of the Party or any of its subsidiaries in connection with any actual or potential Acquisition Proposal, in each case received on or after the date hereof, of which it or any of its subsidiaries, or any of its or their Representatives, is or becomes aware, or any amendments to any of the foregoing. Such notice shall include a description of the material terms and conditions of any such Acquisition Proposal or offer, proposal, expression of interest, or inquiry or request, the identity of the person making such Acquisition Proposal or such offer, proposal, expression of interest, or inquiry or request, a copy of such Acquisition Proposal or such offer, proposal, expression of interest, or inquiry or request and all written communications related thereto and provide such other details of such Acquisition Proposal or offer, proposal, expression of interest, or inquiry or request as the other Party may reasonably request. Each Party shall keep the other Party fully informed on a prompt basis of the status, including any change to the material terms, of any such Acquisition Proposal or such offer, proposal, expression of interest, or inquiry or request and shall respond promptly to all inquiries by the other Party with respect thereto.

7.2.5 Notwithstanding anything in this Agreement to the contrary, but subject to Section 7.3, if at any time following the date of this Agreement and prior to the Effective Date, provided that the relevant Party is then in compliance with all of it obligations under this Agreement (including under

B-74

Table of Contents

Section 7.2), either ECU or Golden receives an Acquisition Proposal which its board of directors concludes in good faith constitutes a Superior Proposal, its board of directors may, subject to compliance with the applicable procedures set forth in Section 7.3 and Section 8.2, terminate this Agreement in order to enter into a definitive agreement with respect to such Superior Proposal.

7.3 Right to Match or Respond to a Potential Adverse Recommendation Change

7.3.1 Each Party covenants that it shall not approve, accept, endorse, recommend or enter into any agreement, understanding or arrangement in respect of a Superior Proposal (other than a confidentiality and standstill agreement permitted by Section 7.2.3) or make an Adverse Recommendation Change unless:

(a): such party (the "Notifying Party") has complied with its obligations under Section 7.2 and the other provisions of this Article 7 and has provided the other Party (the "Notified Party") with a copy of the Superior Proposal or a reasonably detailed description of the relevant Intervening Event, as applicable; and
(b): a period (the "Response Period") of five (5) Business Days has elapsed from the date that is the later of (x) the date on which the Notified Party receives written notice from the ECU Board or the Golden Board, as applicable, that it has determined, subject only to compliance with this Section 7.3, to approve, accept, endorse, recommend or enter into a binding written agreement to proceed with the Superior Proposal or to make the Adverse Recommendation Change, and (y) the date the Notified Party receives a copy of the Superior Proposal or the description of the Intervening Event, as applicable.

7.3.2 During the Response Period, the Notified Party shall have the right, but not the obligation, to offer to amend the terms of this Agreement and the Plan of Arrangement. During the Response Period, the Notifying Party shall negotiate in good faith with the Notified Party to make such amendments to the terms of this Agreement and the Arrangement as would enable the Notifying Party and the Notified Party to proceed with the transactions contemplated by this Agreement on such amended terms or to obviate the need for the Adverse Recommendation Change. Within five (5) Business Days (the "Review Period") of any such proposal by the Notified Party to amend the terms of this Agreement and the Plan of Arrangement, including an increase in, or modification of, the aggregate Consideration and an alteration of the nature of the transactions contemplated hereby, the ECU Board or the Golden Board, as applicable, shall review and determine whether the Acquisition Proposal to which the Notified Party is responding would continue to be a Superior Proposal , or whether the Adverse Recommendation Change is still necessary, when assessed in light of this Agreement and the Plan of Arrangement as they are proposed by the Notified Party to be amended. Such determination shall be made by the ECU Board or the Golden Board, as applicable, in consultation with the ECU Financial Advisor and ECU Fairness Advisor or Golden Financial Advisor, as applicable, and outside legal counsel, and shall be communicated to the Notified Party by no later than the last day of the Review Period. If the ECU Board or the Golden Board, as applicable, determines that the Acquisition Proposal to which the Notified Party is responding would not continue to be a Superior Proposal, or the Adverse Recommendation Change would not be necessary, when assessed in light of this Agreement and the Plan of Arrangement as they are proposed by the Notified Party to be amended, the Notifying Party shall enter into an amendment to this Agreement to give effect to such amendments and the ECU Board or the Golden Board, as applicable, shall promptly reaffirm its recommendation of the Plan of Arrangement on the same basis as described in Section 2.5(b) or Section 2.11(b), as applicable, by the prompt issuance of a press release to that effect. If the ECU Board or the Golden Board, as applicable, determines that the Acquisition Proposal, if any, to which the Notified Party is responding would continue to be a Superior Proposal when assessed against this Agreement and the Plan of Arrangement as they are proposed by the Notified Party to be amended, the Notifying Party may approve and recommend that ECU Securityholders or Golden

B-75

Stockholders, as applicable, accept such Superior Proposal and may terminate this Agreement pursuant to Section 8.2.1(c)(ii) or 8.2.1(d)(ii), as applicable, in order to accept or enter into a binding written agreement to proceed with the Superior Proposal; provided that, for greater certainty, any determination by the board of directors of the Notifying Party to approve and recommend that ECU Securityholders or Golden Stockholders, as applicable, accept such Superior Proposal without terminating this Agreement pursuant to Section 8.2.1(c)(ii) or 8.2.1(d)(ii), as applicable, shall for all purposes hereof constitute an ECU Board Change in Recommendation or a Golden Board Change in Recommendation, as applicable; and provided further that the Notifying Party shall pay the ECU Termination Fee or the Golden Termination Fee, as applicable, required by Section 7.4 concurrently with any such termination of this Agreement pursuant to Section 8.2.1(c)(ii) or 8.2.1(d)(ii), as applicable.

7.3.3 Where the Notifying Party has provided the Notified Party notice pursuant to Section 7.3.1(b) and the ECU Meeting or the Golden Meeting, as applicable, is scheduled to be held prior to the expiry of the Response Period or the Review Period and the Notified Party requests in writing that the ECU Meeting or the Golden Meeting, as applicable, proceed, the Notifying Party shall continue to take all reasonable steps necessary to hold the ECU Meeting or the Golden Meeting, as applicable, and to cause the Arrangement Resolution or the Golden Meeting Resolution, as applicable, to be voted on at the ECU Meeting or the Golden Meeting, as applicable. Alternatively, if directed to do so by the Notified Party, the Notifying Party shall postpone or adjourn the ECU Meeting or the Golden Meeting, as applicable, as directed by the Notified Party to a date designated by the Notified Party (which shall not be later than twenty (20) days after the scheduled date of the ECU Meeting or the Golden Meeting, as applicable, or the reconvening of any previous postponement or adjournment thereof and not later than five (5) Business Days prior to the Outside Date), and the ECU Board or the Golden Board, as applicable, shall waive the proxy-cut off time if requested to do so by the Notified Party and shall, in the event that the Parties amend the terms of this Agreement pursuant to Section 7.3.2, ensure that the details of such amended Agreement are communicated to the ECU Securityholders or the Golden Stockholders, as applicable, prior to the resumption of the postponed or adjourned ECU Meeting or the Golden Meeting, as applicable.

7.3.4 Each successive amendment to any of the material terms of an Acquisition Proposal shall constitute a new Acquisition Proposal for the purposes of this Section 7.3 and the Notified Party shall be afforded a new Response Period and the rights afforded in paragraph 7.3.2 in respect of each such Acquisition Proposal.

7.4 Expenses and Termination Fees

Table of Contents

subsidiaries for six (6) years from the Effective Time with respect to claims arising from or related to facts or events that occurred at or prior to the Effective Time, in each case provided that if comparable coverage may not be obtained at the maximum purchase price per year specified above, then the coverage shall be as comparable as possible at such price, to be determined by Golden, acting reasonably.

(b): Golden agrees that it shall cause ECU and its subsidiaries to honour all rights to expense reimbursement, indemnification or exculpation now existing in favour of present and former officers and directors of ECU and its subsidiaries as provided for in their respective articles and by-laws, and acknowledges that such rights shall survive the completion of the Plan of Arrangement and shall continue in full force and effect for a period of not less than six (6) years from the Effective Date.

(A): such Golden Replacement December 2009 Warrants will be exercisable to acquire that number of shares of Golden Stock as the holders of December 2009 Warrants so transferred and assigned would have acquired if such holders had exercised such December 2009 Warrants immediately prior to the Effective Time and had received ECU Shares in exchange therefor; provided, however, that if the foregoing would otherwise result in a holder of December 2009 Warrants receiving, in the aggregate, Golden Replacement December 2009 Warrants exercisable for a fraction of a share of Golden Stock, the aggregate number of Golden Replacement December 2009 Warrants received in exchange for such holder's December 2009 Warrants shall be determined in accordance with the provisions of Section 4.4;
(B): the exercise price for each such Golden Replacement December 2009 Warrant shall be $18.00 (being $0.90, the exercise price per December 2009 Warrant, divided by the Exchange Ratio); and
(C): the terms and conditions otherwise applicable to such Golden Replacement December 2009 Warrants shall be those set forth in the December 2009 Warrant Indenture (as amended and supplemented by the supplemental indenture referred to in Section 3.1(d)(iv));

the holder of each December 2009 Warrant transferred and assigned to Golden in accordance with Section 3.1(d)(i) shall cease to be the holder thereof and shall cease to have any rights as a holder or former holder in respect of such December 2009 Warrant and the name of such holder shall be removed from the register of holders maintained by or on behalf of ECU in respect of the December 2009 Warrants as of the Effective Time and added to the register of holders maintained by or on behalf of Golden in respect of Golden Replacement December 2009 Warrants as of the Effective Time;

(iii)

each December 2009 Warrant transferred and assigned to Golden in accordance with Section 3.1(d)(i) shall, without any further action by or on behalf of Golden, be cancelled immediately following such exchange and Golden shall be deemed to have executed and delivered all consents, approvals, releases, assignments and waivers, statutory, contractual or otherwise, required to cancel such December 2009 Warrant in accordance with this Section 3.1(d)(iii); and

(i): 0.05 shares of Golden Stock; provided, however, that if the provisions of this Section 3.1(f)(i) would otherwise result in any such ECU Shareholder receiving, in the aggregate, a fraction of a share of Golden Stock, the aggregate number of shares of Golden Stock received as consideration for the transfer and assignment of such ECU Shareholder's ECU Shares shall be determined in accordance with the provisions of Section 4.4; and
(ii): $0.000394;

with respect to each ECU Share transferred and assigned to Golden in accordance with Section 3.1(e) or Section 3.1(f):

(i): the ECU Shareholder that was the registered holder thereof immediately prior to such transfer and assignment shall cease to be the registered holder thereof, the name of such ECU Shareholder shall be removed from the register of holders maintained by or on behalf of ECU in respect of the ECU Shares as of the Effective Time, and the name of Golden will, as of the Effective Time, be added to the register of holders maintained by or on behalf of ECU in respect of the ECU Shares as the holder of the number of ECU Shares so transferred and assigned to Golden as of the Effective Time;

(D): the aggregate exercise price of such Golden Replacement Options shall be equal to the aggregate exercise price of the ECU Options replaced by such Golden Replacement Options, such calculation to be applied separately to each grant of ECU Options (attached as Exhibit A is an example of the calculation of the exercise price per Golden Replacement Option); and

(iii): each ECU Option transferred and assigned to Golden in accordance with Section 3.1(h)(i) shall, without any further action by or on behalf of Golden, be cancelled immediately following such transfer and assignment and Golden shall be deemed to have executed and delivered all consents, approvals, releases, assignments and waivers, statutory, contractual or otherwise, required to cancel such ECU Option in accordance with this Section 3.1(h)(ii);

provided that none of the foregoing will occur or will be deemed to occur unless all of the foregoing occurs.

3.2 Adjustments to Consideration

The Consideration payable to an ECU Securityholder pursuant to Section 3.1 will be adjusted to reflect fully the effect of any stock split, reverse split, dividend (including any dividend or distribution of ECU Shares or securities convertible into ECU Shares), consolidation, reorganization, arrangement, recapitalization or other like change with respect to ECU Shares occurring after the date of the Arrangement Agreement and prior to the Effective Time.

ARTICLE 4
CERTIFICATES AND PAYMENTS

4.1 Payment of Consideration

(a)

Following receipt of the Final Order and prior to the filing of the Articles of Arrangement with the Enterprise Registrar in accordance with the terms of the Arrangement Agreement, Golden shall deposit with the Depositary in escrow, for the benefit of holders of ECU Securities, sufficient funds, shares of Golden Stock and Golden Replacement Warrants in the aggregate amounts necessary to pay the Consideration required by this Plan of Arrangement. All money deposited or caused to be deposited shall be cash denominated in Canadian dollars in same day funds payable at Montreal, Québec and shall not be used for any purpose except as provided in this Plan of Arrangement.

(b)

Subject to surrender to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented outstanding ECU Shares or ECU Warrants, together with a duly completed and executed Letter of Transmittal and such additional documents and instruments as the Depositary may reasonably require, following the Effective Time the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder, the Consideration to which such holder is entitled under this Plan of Arrangement, less any amounts withheld pursuant to Section 4.5, and any certificate so surrendered shall forthwith be cancelled.

(c)

Until surrendered as contemplated by this Section 4.1, each certificate that immediately prior to the Effective Time represented ECU Shares or ECU Warrants shall be deemed after the Effective Time to represent only the right to receive, upon such surrender, the Consideration to which the holder thereof is entitled in lieu of such certificate as contemplated by Section 3.1 and this Section 4.1, less any amounts withheld pursuant to Section 4.5. Any such certificate formerly representing ECU Shares or ECU Warrants not duly surrendered on or before the sixth anniversary of the Effective Date shall:

(i): cease to represent a claim by, or interest of, any former holder of ECU Shares or ECU Warrants of any kind or nature against or in ECU or Golden (or any successor to any of the foregoing); and
(ii): be deemed to have been surrendered to Golden and shall be cancelled.

(d)

Any right or claim to payment hereunder that remains outstanding on the sixth anniversary of the Effective Date shall cease to represent a right or claim of any kind or nature whatsoever and the right of the former ECU Securityholder to receive the Consideration to which such holder is entitled pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited, for no consideration, to Golden (or any successor of Golden).

C-11

Table of Contents

(e): No holder of ECU Securities shall be entitled to receive any consideration with respect to such ECU Securities other than the Consideration to which such holder is entitled in accordance with Section 3.1 and this Section 4.1 and, for greater certainty, no such holder will be entitled to receive any interest, dividends, premium or other payment in connection therewith.

4.2 Lost Certificates

In the event any certificate which immediately prior to the Effective Time represented one or more outstanding ECU Shares or ECU Warrants that are entitled to Consideration pursuant to Section 3.1 shall have been lost, stolen or destroyed, upon the making of an affidavit or statutory declaration of that fact by the person claiming such certificate to be lost, stolen or destroyed and who was listed immediately prior to the Effective Time as the registered holder thereof on the share register or warrant register maintained by or on behalf of ECU, as applicable, the Depositary will deliver in exchange for such lost, stolen or destroyed certificate the Consideration that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, provided that the holder to whom the Consideration is to be delivered shall, as a condition precedent to the delivery, give a bond satisfactory to Golden and the Depositary in such sum as Golden and the Depositary may direct (each acting reasonably), or otherwise indemnify Golden and the Depositary in a manner satisfactory to Golden and the Depositary (each acting reasonably) against any claim that may be made against Golden or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed.

4.3 Distributions with Respect to Unsurrendered Certificates

No dividend or other distribution declared or paid after the Effective Time with respect to Golden Stock shall be delivered to the holder of any certificate formerly representing ECU Shares unless and until the holder of such certificate shall have complied with the provisions of Section 4.1. Subject to applicable law and to Section 4.1 at the time of such compliance, there shall, in addition to the delivery of the Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of any dividend or other distribution declared or made after the Effective Time with respect to the Golden Stock to which such holder is entitled in respect of such holder's Consideration.

4.4 No Fractional Securities

No fractional shares of Golden Stock, fractional Golden Replacement Options or fractional Golden Replacement Warrants shall be issued to any person pursuant to this Plan of Arrangement. The number of shares of Golden Stock, Golden Replacement Options and Golden Replacement Warrants to be issued to any person pursuant to this Plan of Arrangement shall be rounded up or down, as applicable, to the nearest whole share of Golden Stock. For greater certainty, where such fractional interest is greater than or equal to 0.5, the number of shares of Golden Stock, Golden Replacement Options or Golden Replacement Warrants, as applicable, to be issued will be rounded up to the nearest whole number and where such fractional interest is less than 0.5, the number of shares of Golden Stock, Golden Replacement Options or Golden Replacement Warrants, as applicable, to be issued will be rounded down to the nearest whole number. In calculating such fractional interests, all ECU Shares, ECU Options or ECU Warrants, as applicable, registered in the name of or beneficially held by an ECU Securityholder or its nominee shall be aggregated.

4.5 Withholding Rights

C-12

Table of Contents

provision of applicable Laws in respect of Taxes. To the extent that such amounts are so deducted and withheld, such amounts shall be treated for all purposes hereof as having been paid to the person to whom such amounts would otherwise have been paid. Golden, ECU or the Depositary, as applicable, may sell or otherwise dispose of such portion of the Consideration otherwise payable to such holder as is necessary to provide sufficient funds to enable Golden, ECU or the Depositary, as applicable, to comply with such deduction and/or withholding requirements and Golden, ECU and the Depositary, as applicable, shall notify the holder thereof and remit any unapplied balance of the net proceeds of such sale.

4.6 Calculations

All aggregate amounts of cash consideration to be received under this Plan of Arrangement will be calculated to the nearest cent ($0.01). All calculations and determinations made in good faith by Golden, ECU or the Depositary, as applicable, for the purposes of this Plan of Arrangement shall be conclusive, final, and binding.

ARTICLE 5
DISSENT RIGHTS

5.1 Dissent Rights

Each registered holder of ECU Shares shall be entitled to exercise Dissent Rights in respect of the Arrangement in the manner set out in Chapter XIV of the QBCA, as modified by the Interim Order and this Article 5.

Such modifications include the following:

(a): the written notice of intent to exercise the right to demand the repurchase of ECU Shares contemplated by Section 376 of the QBCA must be sent to the registered office of ECU no later than 5:00 PM on the date that is two (2) Business Days before the ECU Meeting;
(b): Golden shall be registered as transferee of all the ECU Shares of the Dissenting Shareholders, as per Section 3.1(e) hereof, and shall, in lieu of ECU, pay the offered repurchase price to all Dissenting Shareholders;
(c): Golden shall assume all obligations of ECU for the purposes of Sections 382 to 388 of the QBCA and shall be entitled to exercise all of the rights of ECU thereunder, in the place and stead of ECU; and
(d): the fair value payable by Golden to a Dissenting Shareholder, may, at the option of Golden, be paid by way of issuance of shares of Golden Stock.

In no case shall Golden, ECU or any other person be required to recognize any holder of ECU Shares who exercises Dissent Rights as a holder of ECU Shares after the Effective Time.

Registered holders of ECU Shares who renounce, or are deemed to renounce, their right to demand the repurchase of their ECU Shares shall be deemed to have participated in the Arrangement, as of the Effective Time, and shall be entitled to receive the consideration to which holders of ECU Shares who have not exercised Dissent Rights are entitled under Section 3.1(f) hereof (less any amounts withheld pursuant to Section 4.5).

For greater certainty, (a) no holder of ECU Options, ECU Warrants or Convertible Notes shall be entitled to Dissent Rights in respect of such holder's ECU Options, ECU Warrants or Convertible Notes (including, for greater certainty, any ECU Shares issued to a holder of Convertible Notes in connection with the exchange of Convertible Notes pursuant to Section 3.1(a) hereof) and (b) in addition to any other restrictions in Chapter XIV of the QBCA, no ECU Shareholder who has failed

C-13

Table of Contents

to exercise all the voting rights carried by the ECU Shares held by such ECU Shareholder against the Arrangement Resolution shall be entitled to exercise Dissent Rights with respect to the Arrangement.

ARTICLE 6
AMENDMENTS AND TERMINATION

6.1 Amendments to Plan of Arrangement

(a): Golden and ECU reserve the right to amend, modify or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Date, provided that each such amendment, modification or supplement must be (i) set out in writing, (ii) agreed to in writing by each of Golden and ECU, (ii) filed with the Court, subject to such conditions as the Court may impose, and, if made following the ECU Meeting, approved by the Court, and (iv) communicated to holders of ECU Shares, Convertible Notes, ECU Options and ECU Warrants if and as required by the Court.
(b): Any amendment, modification or supplement to this Plan of Arrangement may be proposed by ECU at any time prior to the ECU Meeting provided that Golden shall have consented thereto in writing, with or without any other prior notice or communication, and, if so proposed and accepted by the ECU Securityholders voting at the ECU Meeting (other than as may be required under the Interim Order), shall become part of this Plan of Arrangement for all purposes.
(c): Any amendment, modification or supplement to this Plan of Arrangement that is approved by the Court following the ECU Meeting shall be effective only if: (i) it is consented to in writing by each of Golden and ECU, each acting reasonably; and (ii) if required by the Court, it is consented to by ECU Securityholders voting in the manner directed by the Court.
(d): This Plan of Arrangement may be withdrawn prior to the Effective Time in accordance with the terms of the Arrangement Agreement.
(e): Golden and ECU may, at any time following the ECU Meeting, amend, modify or supplement this Plan of Arrangement without the approval of ECU Securityholders provided that each amendment, modification or supplement (i) must be set out in writing, (ii) must concern a matter which, in the reasonable opinion of each of ECU and Golden is of an administrative nature required to better give effect to the implementation of this Plan of Arrangement, (iii) is not adverse to the financial or economic interests of ECU Securityholders entitled to receive the Consideration under Section 3.1, and (iv) would not adversely affect the rights of Dissenting Shareholders, if any.

ARTICLE 7

EXHIBIT A

EXAMPLE OF CALCULATION OF
GOLDEN REPLACEMENT OPTION EXERCISE PRICE

1.: An ECU Optionholder has been granted ECU Options which, if fully exercised, would entitle the ECU Optionholder to acquire 1,000 ECU Shares.
2.: The exercise price of such ECU Options is $1 per ECU Option, or $1,000 in the aggregate.
3.: On the Arrangement being implemented, an ECU Shareholder holding 1,000 ECU Shares would receive 50 (being 1,000 multiplied by the Exchange Ratio) shares of Golden Stock.
4.: The ECU Optionholder will, on implementation of the Arrangement, receive Golden Replacement Options which, if fully exercised, will entitle the ECU Optionholder to acquire 50 shares of Golden Stock.
5.: The exercise price of such Golden Replacement Options is, in the aggregate, $1000 and, upon payment of such aggregate exercise price, the ECU Optionholder would receive 50 shares of Golden Stock.
6.: Therefore, the exercise price per Golden Replacement Option will be equal to $1,000 ÷ 50, or $20.00.

ECU SILVER MINING INC.
(A Development Stage Company)

NOTES TO CONSOLIDATED INTERIM FINANCIAL STATEMENTS

for the three months ended March 31, 2011 and 2010
(unaudited, expressed in Canadian dollars unless otherwise noted)

1. NATURE OF ACTIVITIES

ECU Silver Mining Inc. was incorporated in the province of Quebec, Canada and its shares are publicly traded. The Company's registered office is 1116 Avenue Granada, Rouyn-Noranda, Quebec, Canada and its executive office is located at 87 Front Street East, 2nd Floor, Toronto, Ontario, Canada. It is engaged in the acquisition, exploration and development of mining properties in Mexico that are mainly gold-bearing and silver-bearing. The Company has earned revenues from its exploration and development activities and is considered to be in the development stage. It has not yet determined whether a sufficient proportion of its mineral resources are economically exploitable and, accordingly, has not yet determined whether the mining properties contain economic mineral reserves.

These consolidated financial statements have been prepared on a going concern basis, which assumes that the Company will, in the ordinary course of business, be able to realize its assets and discharge its liabilities. The recoverability of the accumulated costs shown for mining properties and related deferred costs is dependent upon the existence of economically recoverable reserves, future profitable production, and on the Company's ability to obtain the necessary financing to fund it's operations.

2. BASIS OF PREPARATION

a) Statement of Compliance

The unaudited consolidated interim financial statements ("interim financial statements") of ECU Silver Mining Inc. and all its subsidiaries (together referred to as "ECU" or the "Company") for the first quarter ended March 31, 2011 have been prepared in accordance with IAS 34, Interim Financial Reporting. These are the Company's first International Financial Reporting Standards ("IFRS") consolidated interim financial statements for part of the period covered by the first IFRS annual financial statements, and IFRS 1, First-time Adoption of International Financial Reporting Standards, has been applied. The consolidated interim financial statements do not include all of the information required for full annual consolidated financial statements. Accordingly certain information and disclosures normally included in annual financial statements prepared in accordance with IFRS, as issued by the International Accounting Standards Board ("IASB"), have been omitted or condensed.

The significant accounting policies applied in these consolidated interim financial statements are presented in note 3 and are based on IFRS in effect as of June 13, 2011. Any changes to IFRS that will impact the annual consolidated financial statements for the year ending December 31, 2011 could result in a restatement of these consolidated interim financial statements.

An explanation of how the transition to IFRS has affected the reported financial position, financial performance and cash flows of the Company is provided in note 23. This note includes reconciliations of equity, net earnings and total comprehensive income for the 2010 comparative periods, and of equity at the date of transition reported under previous Canadian generally accepted accounting principles to those reported under IFRS for those periods and at the date of transition.

b) Basis of Measurement

The consolidated interim financial statements have been prepared on a historical cost basis, except for the following, which are measured at fair value:

•: derivative financial instruments
•: financial instruments at fair value through profit and loss
•: available-for-sale assets

The methods used to measure fair values are discussed further in note 3 1.

c) Basis of Consolidation

Subsidiaries related to significant properties of the Company are accounted for as follows:

Name	Location			Accounting Method

BLM Minera Mexicana S.A de C.V.	Mexico	100	%	Consolidated
Minera William S.A de C.V.	Mexico	100	%	Consolidated
Minera Labri S.A.de C.V.	Mexico	100	%	Consolidated

(unaudited, expressed in Canadian dollars unless otherwise noted)

2. BASIS OF PREPARATION (Continued)

The consolidated financial statements also included the Company's share of the income, expenses, assets and liabilities of the San Diego Joint Venture which involves jointly controlled exploration assets.

All inter-company transactions and balances have been eliminated.

3. SIGNIFICANT ACCOUNTING POLICIES

a) Presentation currency

The consolidated interim financial statements are presented in Canadian dollars which is the functional currency of ECU Silver Mining Inc. The functional currency of the Mexican subsidiaries is the Mexican peso. These consolidated interim financial statements have been translated to the Canadian dollar in accordance with IAS 21 The Effects of Changes in Foreign Exchange Rates. These guidelines require that assets and liabilities be translated using the exchange rate at period end, and income, expenses and cash flow items are translated using the rate that approximates the exchange rates at the dates of the transactions (i.e. the average rate for the period). Subsequent to the adoption of IFRS, all resulting exchange differences are recorded in the foreign currency translation reserve.

b) Foreign currency transactions

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at reporting period exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in profit or loss. Non-monetary assets are translated at historical exchange rates.

c) Use of Estimates

The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.

Significant accounts that require estimates as the basis for determining the stated amounts include, but are not limited to, the accounting for accounts receivable and doubtful accounts, estimating the net realizable value of inventory, asset impairment, accounting for share-based payments, revenue recognition, calculation of depreciation, anticipated costs of asset retirement obligations and the valuation of deferred income tax assets and liabilities, mining interests and deferred expenditures. While management believes that these estimates and assumptions are reasonable, actual results could vary significantly.

In determining these estimates, the Company relies on assumptions regarding applicable industry performance and prospects, as well as general business and economic conditions that prevail and are expected to prevail. These assumptions are limited by the availability of reliable comparable data and the uncertainty of predictions concerning future events.

d) Revenue recognition

Revenue is recognized upon delivery when title and risk of ownership of metal and metal bearing concentrates passes to the buyer and when collection is reasonably assured. The contained metal in the concentrates shipped is assayed and the appropriate negotiated amount of recoverable metal contained therein is recorded as revenue based on the then current market rate of the metals. The concentrates are sold under contracts that provide for final prices to be determined by quoted market prices in a period subsequent to the date of the sale. Variations from the provisionally priced sales are recognized as revenue adjustments in the period they occur.

The Company has continued with the accounting practice under Canadian GAAP that, as the Company is in the development stage, all revenues are offset against mining properties and deferred exploration costs.

e) Cash and cash equivalents

The Company's policy is to present cash and temporary investments having a term of three months or less from the acquisition date within cash and cash equivalents.

3. SIGNIFICANT ACCOUNTING POLICIES (Continued)

f) Mining Properties, and Deferred Exploration and Development Expenses

The amounts recorded as mining properties and deferred exploration costs represent exploration, development and associated operating costs incurred to date and are not intended to reflect present or future values. These costs are deferred until the discovery of economically exploitable reserves and the start-up of the production phase on a property-by-property basis or until the property is abandoned. Mining properties are abandoned when management allows property interests to lapse or when they determine that properties are not economically viable. Costs accumulated relating to projects that are abandoned are written-off in the year in which a decision to discontinue the project is made.

When it has been determined that a mining property can be economically developed as a result of establishing proven and probable reserves, costs incurred prospectively to develop the property are capitalized as incurred and are amortized using the units-of-production method over the estimated life of the ore body based upon recoverable ounces to be mined from estimated proven and probable reserves.

The Company is in the development stage and by definition commercial production has not yet commenced. Commercial production occurs when an asset or property is substantially complete, is fully permitted and ready for its intended use. No amortization of mining properties has been charged in these financial statements.

Where there is an indication that impairment may exist, senior management reviews the carrying values of mining properties and deferred exploration expenditures with a view to assessing whether there has been any impairment in value. In the event that it is determined there is an impairment in the carrying value of any property, the carrying value will be written down or written off, as appropriate. There was no impairment write-down required at March 31, 2011.

Supplies and spare parts are valued at the lower of average cost and replacement cost.

g) Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and impairment provisions. Depreciation is provided for plant and equipment on a straight-line basis over the estimated useful lives of the related assets and deferred to mining properties or charged to expense as appropriate. Depreciation is charged separately for each significant part of an item of property, plant and equipment. The following estimated useful lives are being used:


	Buildings		20 years
	Leasehold improvements		2 or 8 years
	Automotive		4 years
	Machinery and equipment		10 years
	Computer equipment		3¹/3 years
	Office equipment		10 years

The estimated useful lives, depreciation method and residuals are reviewed at each reporting date.

h) Asset retirement obligations

The Company records the present value of its legal obligations associated with the asset retirement when the liability is incurred. The corresponding amount is capitalized as part of the related mining property's carrying value. While the associated mining property is in the pre-production stage, the liability is accreted over time through periodic charges to mining property costs. In each subsequent period, the carrying amounts of the asset and the liability are adjusted for changes to the Company's estimate of future cash flows associated with the retirement obligations.

Management estimates that the current present value of legal obligations for asset retirement is de minimis.

i) Income and Mining Taxes

The Company uses the liability method to account for income taxes. Under this method deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured by using enacted or substantively enacted tax rates expected to apply to taxable income in the years during which those temporary differences are expected to be

3. SIGNIFICANT ACCOUNTING POLICIES (Continued)

recovered or settled. Deferred tax asset is only recognized if it can be demonstrated that there will be taxable profits in future years to utilize the deductible temporary differences and unused tax losses. The effect on future tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

j) Basic and Diluted Loss per Share

The basic loss per share is calculated using the weighted average number of shares outstanding during the period. We follow the treasury stock method in calculating diluted earnings per share. Under this method, the weighted average number of shares includes the potentially dilutive effects of the conversion of in-the-money stock options and warrants into common shares. The effect of potential issuances of shares under options and warrants would be anti-dilutive when a loss is reported, and therefore basic and diluted losses per share are the same.

k) Stock-based compensation

Stock options granted to employees and non-employees are accounted for using the fair value method. Under this method, the compensation cost is measured as at the date of the grant by applying the Black-Scholes option pricing model. The determined fair value is recognized as a cost over the vesting period with a corresponding increase to contributed surplus. Those costs which relate to employees engaged in exploration and development of mining properties, are capitalized to deferred mining property costs. On the exercise of stock options, consideration paid and the associated contributed surplus amount is transferred to common shares.

l) Financial Instruments

All financial assets are classified as either at fair value through profit or loss or amortized cost. Financial assets must be designated as at fair value through profit or loss except for financial assets classified at amortized cost if the objective is to collect contractual cash flows made up of principal and interest payments which are paid at a specified date. Cash and cash equivalents and accounts receivable are designated as amortized cost. All financial liabilities are designated at amortized cost unless the Company on initial recognition has classified the liability at fair value. All financial derivatives including embedded derivatives are classified as at fair value through profit or loss unless the financial derivative meets the criteria of an equity instrument. All financial assets and liabilities designated as amortized cost use the effective interest method. Impairment provisions are made if and only if there is objective evidence that the financial asset is impaired.

Transaction costs such as arrangement and advance fees charged by the Company's principal lender in connection with long term debt are expensed at the time they are incurred.

Fair value hierarchy:

Financial instruments recorded at fair value are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:

Level 1 reflects valuation based on quoted prices observed in active markets for identical assets or liabilities.

Level 2 reflects valuation techniques based on inputs that are quoted prices of similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; inputs other than quoted prices used in a valuation model that are observable for that instrument; and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 reflects valuation techniques with significant unobservable market inputs.

A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring fair value. The financial instruments in the Company's financial statements, measured at fair value, are the cash and cash equivalents.

m) Financial derivatives — warrants

A financial derivative such as a warrant which will be settled with the Company's own equity instruments will be designated as an equity instrument if the derivative has no contractual obligation and is to acquire a fixed number of the entity's own equity instruments for a fixed amount of Canadian dollars. A warrant will be considered as a financial liability at fair value through profit

or loss if it is to acquire either a variable number of equity instruments or consideration. However, if the warrant is for a fixed number of equity instruments but the exercise is in a currency other than the functional currency the warrant will be a financial liability unless the warrants were offered pro rata to all of its existing owners of the same class of its own non-derivative equity instruments.

n) Financial derivatives — embedded derivatives

Certain derivatives embedded in other financial instruments are treated as separate derivatives when their economic characteristics and risks are not closely related to those of the host contract and the host contract is not carried at fair value through profit or loss. These embedded derivatives are separately accounted for at fair value, with changes in fair value recognised in profit or loss.

o) Impairment of non-financial assets

The Company's non-financial assets include mining properties and property, plant and equipment. The assets are reviewed for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized in profit or loss when the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs to sell and value in use. Where an individual asset cannot be assessed for impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets that suffered an impairment loss are reviewed for possible reversal of the impairment at each reporting date and any reversals are recognized in profit or loss.

4. RECENT ACCOUNTING PRONOUNCEMENTS

Certain pronouncements have been issued by the International Accounting Standards Board ("IASB") or the International Financial Reporting Interpretation Committee ("IFRIC") that are mandatory for accounting periods after December 31, 2010. Many are not applicable or do not have a significant impact to the Corporation and have been excluded from the discussion below.

a) New standards, amendments and interpretations issued effective for the financial year beginning January 1, 2011

Revised IAS 24 (revised), 'Related party disclosures', was issued in November 2009 and supersedes IAS 24, 'Related party disclosures', issued in 2003. IAS 24 (revised) is mandatory for periods beginning on or after 1 January 2011. The revised standard clarifies and simplifies the definition of a related party.

Classification of rights issues' (amendment to IAS 32), issued in October 2009. The amendment addresses the accounting for rights issues, warrants and options that are denominated in a currency other than the functional currency of the issuer. Provided certain conditions are met, such rights issues are now classified as equity regardless of the currency in which the exercise price is denominated. The Company will apply the amended standard from January 1, 2011 where applicable. It is not expected to have any impact on the Company's financial statements.

IFRIC 19, 'Extinguishing financial liabilities with equity instruments', effective July 1, 2010. The interpretation clarifies the accounting by an entity when the terms of a financial liability are renegotiated and result in the entity issuing equity instruments to a creditor of the entity to extinguish all or part of the financial liability (debt for equity swap). It requires a gain or loss to be recognised in profit or loss, which is measured as the difference between the carrying amount of the financial liability and the fair value of the equity instruments issued. It is not expected to have any impact on the Company's financial statements.

b) New standards, amendments and interpretations issued effective for the financial year beginning January 1, 2013 but early adopted by the Company

IFRS 9, 'Financial instruments', issued in November 2009 and amended in October 2010. This standard is the first step in the process to replace IAS 39, 'Financial instruments: recognition and measurement'. IFRS 9 introduces new requirements for classifying and measuring financial assets and financial liabilities. The standard is not applicable until January 1, 2013 but the Company is early adopting as the profile of the Company's financial assets and financial liabilities would be more appropriately classified under IFRS 9 rather than IAS 39.

Term loan

As at period end the Company owed $16,113,337 ($16,618,541 US dollars) on its term loan. The facility was restructured during the period. Principal repayments under the amended facility are payable in thirty equal monthly payments commencing July 31, 2011 and ending December 31, 2013. The terms of interest payable under the restructured facility were unchanged being payable quarterly and calculated at the greater of 12% and 1-month London Interbank Offered Rate plus 6%. The effective rate of interest on the loan is 12.8%. The loan is secured by a first mortgage covering certain of the current mining properties of the Company's Mexican subsidiaries, as well as the current and future facilities constructed thereon.

The Company previously entered into contracts which terminated the legal actions related to title of four mineral concessions on the Velardeña property and settled the title matter. Under the terms of the contracts, the Company agreed to pay a total of $6,000,000 US dollars in a series of 6 payments of $1,000,000 US dollars, commencing May 19, 2009 and running semi-annually thereafter ending November 17, 2011, without interest. Under the terms of the contracts, a 30% interest in the title to the concessions will transfer to the counterparty should the Company fail to make the payments agreed there under.

The fair value of the debt at initial recognition was estimated using the discounted cash flow method. The debt is being accreted over the expected life of 2¹/2 years using the effective interest method at a rate of 15.5%.

Facilities loan

This loan carries interest at 10% and is repayable over a 5 year term in monthly payments of principal and interest of $1,698 and matures February 2013.

10. SHARE CAPITAL

The Company's authorized share capital consists of an unlimited number of common shares without par value

In 2009, the Company completed an offering of 16,946,000 special warrants (the "Special Warrants") to subscribers on a private placement basis at a price of $0.72 per Special Warrant for a total gross proceeds of $12,201,120. The net proceeds of the issue of $10,801,114 were reflected in a separate category in Shareholders' Equity at January 1, 2010.

Effective January 27, 2010, following receipt of a short form prospectus filing, all the outstanding Special Warrants were deemed to be exercised, resulting in the issuance of 16,946,000 units (the "Unit"). Each Unit was comprised of one common share in the share capital of the Company and one-half of one warrant to purchase a common share in the share capital of the Company (each whole warrant, a "Purchase Warrant"). Each Purchase Warrant entitles the holder thereof to purchase one common share in the share capital of the Company at an exercise price of $0.90 per Purchase Warrant at any time before December 9, 2011. The gross proceeds of the Special Warrant offering were assigned on deemed conversion $10,421,790 to common shares and $1,779,330 to warrants. The fair value of the warrants was estimated on the date of the private placement based on the Black-Scholes option pricing model using the following assumptions: risk-free interest rate 1.0%, expected life 2 years, expected volatility 65%, and expected dividend yield 0%. The costs of the private placement issue have been reflected as share issuance costs.

11. STOCK OPTIONS

Under the terms of the Company's stock option plan (the "Plan") 14,252,398 Common Shares have been reserved for issuance. Options under the Plan are permitted to be granted to directors, officers, employees and consultants of the Company, provided that the maximum number of Common Shares which may be reserved for issuance to any one beneficiary in any 12 month period may not exceed 5% of the number of Common Shares then issued and outstanding or 2% in the case of a beneficiary who is conducting investor relations activities. The exercise price of options granted under the Plan is not permitted to be less than the closing price of the Common Shares on the day preceding the grant of the options, less any discount allowed by applicable securities legislation. Options granted pursuant to the Plan will have an exercise period of no more than 10 years, or such lesser period as may be permitted by applicable securities legislation.

A summary of changes in common stock options outstanding is presented below:

	Three months ended March 31, 2011					Year ended December 31, 2010

Intangible Asset

In January 2005, the Company acquired the rights to use a technology which is expected to increase material recuperation of current and future Mexican projects. At the time the agreement was reached the Company issued 500,000 common shares and the Company is bound to issue an additional 500,000 common shares should it choose to use the technology at a commercial scale. In addition, the agreement provides that the Company pay royalties of 1.5% of all production resulting from the application of the technology in Mexican properties. The technology was not employed in the current period.

16. MANAGEMENT OF CAPITAL

As at March 31, 2011, the Company had long-term debt of $16,618,541 US dollars. In January 2011, the Company restructured the facility with its lender. Principal repayments under the amended facility are payable in thirty equal monthly payments commencing July 31, 2011 and ending December 31, 2013.

The Company is also obligated to semi-annual payments of $1,000,000 US dollars due under terms of a mineral concession agreement. The two final payments are due May 17, 2011 and November 17, 2011

Based on current plans and estimates management believes that its operations can be funded through working capital, potential future credit facilities, and cash flow expected to be generated from the sale of products from its operations. As discussed note 1, the Company is dependent on its ability to raise the necessary capital to fund its operations and management can not provide assurance that it will ultimately be able to complete the required funding transactions. Furthermore, since we do not have proven and probable reserves we can not predict with confidence the level of cash flows that will be generated from the milling operations. As such, we may need to either restructure our long term debt so that repayment requirements match the cash generation capability or raise additional equity in the alternate. Management can provide no guarantee that the Company will be successful in these transactions should they be required.

The Company is not subject to any externally imposed capital requirements and there has been no change with respect to the overall capital risk management strategy during the period.

17. FINANCIAL INSTRUMENTS

The Company's financial instruments consist of the following:

		March 31, 2011				December 31, 2010				January 1, 2010

		Carrying Value		Fair Value		Carrying Value		Fair Value		Carrying Value		Fair Value
Financial Assets
— Amortized cost
	Cash and cash equivalents		1,219,934		1,219,934		344,826		344,826		7,647,023		7,647,023
	Accounts receivable		1,138,589		1,138,589		1,437,570		1,437,570		951,802		951,802
	Advances and deposits		288,863		288,863		187,912		187,912		112,195		112,195
Financial Liabilities
— Amortized cost
	Accounts payable and accrued liabilities		5,143,039		5,143,039		3,600,407		3,600,407		4,360,474		4,360,474
	Customer advances		3,611,760		3,611,760		5,017,757		5,017,757		1,944,350		1,944,350
	Long-term debt		17,982,771		17,982,771		18,382,120		18,382,120		21,089,821		21,089,821

The fair value of all financial assets approximate their carrying values due to their short-term maturity. For financial liabilities, except in the case of long-term debt, the fair value approximates the carrying amount because the market rate of interest is paid. There are no outstanding financial instruments measured at fair value and accordingly no disclosure of the fair value hierarchy.

18. SAN DIEGO — JOINT VENTURE

The Company's consolidated financial statements include the following amounts related to the San Diego Joint Venture which is considered a jointly controlled asset:



Long term assets
	Mining property costs	715,992		630,223		615,791
Cash flows resulting from investing activities
	Mining property costs	(74,102	)	(9,506	)	(60,876	)

ECU's share in the joint venture with Golden Tag Resources Ltd ("Golden Tag") is 50% of the mining property costs incurred following the $1,500,000 US dollars earn in by Golden Tag as well as a 50% interest in the rights of the San Diego property.

19. LOSS CARRY FORWARDS

These financial statements do not recognize a deferred tax asset for tax loss carry forwards as it cannot be demonstrated that the Company will have taxable profits in the future with which to offset these losses. The Company will review at each reporting date the unrecognized deferred tax asset to determine whether an asset should be recognized based upon the circumstances at that time.

At December 31, 2010, the Company had non-capital loss carry forwards, available to offset future taxable income for Canadian tax purposes, aggregating $10,209,887 which expire over the period between 2014 and 2030.

At December 31, 2010, the Company had tax loss carry forwards, available to offset future taxable income in Mexico, aggregating $39,566,687 which expire between 2011 and 2020.

20. INCOME TAX EXPENSE

There is no current income tax expense or provision for deferred tax as a result of tax losses and because of recent operating losses the Company cannot demonstrate future taxable profits meaning a deferred tax asset on tax losses carried forward cannot be recognized.

21. RELATED PARTY TRANSACTIONS

Key management personnel includes the members of the management team who directly report to the chief executive officer

23. TRANSITION TO IFRS

For all periods up to and including the year ended December 31, 2010, the Company prepared its financial statements in accordance with Canadian generally accepted accounting principles ("CGAAP"). The financial statements for the three months period ended March 31, 2011 are the first the Company has prepared in accordance with IFRS.

In preparing these financial statements, the opening statement of financial position was prepared as at January 1, 2010, the Company's date of transition to IFRS. This note explains the principal adjustments made in restating the previous CGAAP statement of financial position as at January 1, 2010 and its previously published GAAP financial statements for the year ended December 31, 2010.

Exemptions applied

IFRS 1 'First-Time Adoption of International Financial Reporting Standards' allows first-time adopters certain exemptions from the retrospective application of IFRSs. The Company has elected the following exemptions:

(a): IFRS 2 Share-based Payment has not been applied to the options issued under the Stock Option Plans that were vested prior to January 1, 2010.
(b): designation of previously recognized financial instruments under IFRS 9 based upon the facts and circumstances that exist at the transition date.
(c): The Company has elected to apply IFRS 3 prospectively to business combinations occurring after its transition date. Business combinations occurring prior to the transition date have not been restated.
(d): Accumulated translation differences at January 1, 2010 are shown as zero with the balance transferred to accumulated deficit.

The exceptions under IFRS 1 not to retrospectively apply certain IFRS at the transition date have been applied. The Company's estimates in accordance with IFRS are consistent with estimates made in accordance with previous GAAP (after adjustments to reflect any difference in accounting policies).

Reconciliations

The reconciliations between the previously reported financial results under CGAAP and the current reported financial results under IFRS are provided as follows:

•: reconciliation of equity at January 1, 2010
•: reconciliation of equity at December 31, 2010
•: reconciliation of total comprehensive income for the three months ended March 31, 2010

No reconciliation is required for the consolidated cash flow statement as there are no significant differences.

Equity Reconciliation at January 1, 2010


Total equity reported under CGAAP	64,739,633
Adjustment required in changing from the temporal method	(12,967,165	)
Adjustment required to retrospectively apply IFRS 2	20,109

Total equity reported under IFRS	51,792,577

Equity Reconciliation at December 31, 2010


Total equity reported under CGAAP	59,684,516
Adjustment required in changing from the temporal method	(12,488,463	)

Total equity reported under IFRS	47,196,053

23. TRANSITION TO IFRS (Continued)

Total Comprehensive Income Reconciliation for three months ended March 31, 2010


Total comprehensive loss reported under CGAAP	1,852,350
Adjustment required in changing from the temporal method	(2,209,509	)
Adjustment required to retrospectively apply IFRS 2	81,116

Total comprehensive income reported under IFRS	(276,043	)

Explanation for reconciling items

Under CGAAP the Company used the temporal method in translating foreign operations and non-monetary assets and liabilities in foreign currency to the presentation currency. This adjustment is primarily the impact of translating mining property costs and property plant and equipment at the closing rates on consolidation rather than the historic rates and removing exchange differences on the consolidation of foreign operations from profit or loss and including in equity.

The method of calculating the fair value under IFRS 2 for stock based compensation plans is different than CGAAP due to grading and allowing an assumption for a forfeiture. This adjustment is the impact of this difference.

24. APPROVAL OF THE FINANCIAL STATEMENTS

The consolidated interim financial statements of ECU Silver Mining Inc. for the three months ended March 31, 2011 and 2010 were approved and authorized for issue by the Board of Directors on June 13, 2011.

These consolidated interim financial statements have been amended to include note 25 which presents the material differences between Canadian and United States generally accepted accounting principles ("GAAP"). The amendment was approved and authorized for issue by the Board of Directors on July 14, 2011.

25. AMENDMENT FOR DISCLOSURE OF MATERIAL DIFFERENCES BETWEEN CANADIAN AND UNITED STATES
GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

The Company prepares its consolidated financial statements in Canada in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and in accordance with Interpretations as issued by the International Financial Reporting Interpretations Committee ("IFRIC") which differ in certain respects from GAAP in the United States. The effect of the principal measurement differences between IFRS and United States GAAP are summarized in the following:

NOTES TO CONSOLIDATED INTERIM FINANCIAL STATEMENTS (Continued)

for the three months ended March 31, 2011 and 2010
(unaudited, expressed in Canadian dollars unless otherwise noted)

Notes to consolidated United States GAAP adjustments:

a.: Mining property costs

Under IFRS, exploration and evaluation expenditures on identifiable properties are capitalized. Costs of acquiring mineral properties and related evaluation expenditures during the exploration and evaluation stages include those costs related to the search for mineral resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource. United States GAAP requires that all exploration costs be expensed.

b.: Mining property costs classification in other income

Under IFRS, net revenue or expense derived from a mineral property prior to the production phase of a mine is capitalized and included in the cost of the asset. A United States GAAP adjustment arises because United States GAAP requires that all exploration related costs and associated revenues be expensed. Furthermore, United States GAAP requires that any incremental and direct costs associated with the sale of excavated saleable minerals during the development phase of the mine and prior to the production phase of the mine be classified as Other income and offset by the related amounts of proceeds from the sale of these minerals. Incremental and direct costs are those costs that would otherwise have not been incurred if not for the sale of these minerals.

c.: Stock-based compensation and stock options

Under IFRS, stock-based compensation costs and stock option costs incurred during the exploration or development stage of the mineral properties are capitalized prior to the establishment of proven or probable reserves in circumstances where they are directly related to the exploration and evaluation of an underlying identifiable mineral property. United States GAAP requires that all stock-based compensation costs and stock option costs be expensed.

d.: Convertible debentures

The impact of the differences in treatment between Canadian GAAP and US GAAP of convertible debentures for the periods presented affects solely the March 31, 2009 comparative period. Under Canadian GAAP, convertible debenture proceeds are allocated between their debt and equity component parts based on the relative fair values of the debt component and the embedded conversion feature. The debt component is accreted to the face value of the debentures with the resulting interest expense charged to operations. The costs of the financing are allocated on a proportional basis between the liability and equity portions based on their relative fair values with the liability portion of the costs expensed and the equity portion treated as a reduction of the gross proceeds allocated to the equity component. United States GAAP treats the convertible debenture solely as a liability since the embedded conversion feature does not meet US GAAP requirements for classification as an equity component. The liability is recorded at its full face value since the embedded conversion feature has no intrinsic value on a stand-alone basis and accordingly does not meet the requirements of an equity component under United States GAAP. United States GAAP requires that convertible debentures, net of issuance costs, be accreted to face value over the term ending on the first put date of the debentures which, in this case, is the issuance date of the debentures since the debentures are convertible on demand by the Unit holders. Thus, the debentures' carrying value prior to conversion equalled their face value on the balance sheet.

e.: Foreign currency translation reserve

Under IFRS, the results and financial position of subsidiaries that have a functional currency different from the presentation currency are translated into the presentation currency as follows: assets and liabilities are translated at the closing rate at the reporting date; income and expenses for each income statement item are translated at average exchange rates for the period; and all resulting exchange differences are recognized in other comprehensive income as foreign currency translation reserve. United States GAAP requires that certain non-monetary assets and liabilities in foreign currencies be translated at historical rates such as mining property costs and property plant and equipment. Therefore, for US GAAP purposes, mining property costs and property plant and equipment have been translated at their historical rates such that the IFRS financial statements have been adjusted to reclassify the foreign currency translation reserve from deficit and other reserves to the underlying Balance Sheet items impacted.

f.: Stock based compensation plans fair value

Under IFRS, the method of calculating the fair value of stock based compensation plans includes the requirement to adjust the compensation expense for estimates of non-market vesting conditions, such as options that are not expected to vest (i.e. forfeitures). Furthermore, IFRS grading of stock based compensation for purposes of the determination of fair value is based on each tranche in an award being considered a separate award with its own vesting period and grant date fair value. United States GAAP does not require any initial estimation of non-market vesting conditions (i.e. forfeitures) and the method of calculating fair value does not require the grading of each tranche in an award as a separate award. Therefore, for US GAAP purposes, the method of calculating the fair value for stock based compensation plans differs due to the exclusion of the non-market vesting conditions (i.e. forfeitures) and the exclusion of the grading of each tranche in an award as a separate award.

Notes to consolidated United States GAAP adjustments: (Continued)

g.: Mining property costs classification in statement of cash flow

United States GAAP requires that cash flows relating to mineral property exploration and land use costs be reported as operating activities. However, under IFRS mineral property exploration and evaluation expenditures are classified as investing activities.

Other disclosures:

The following additional information would be presented if these consolidated financial statements were presented in accordance with U.S. GAAP:

i.: Auditor's Report: Emphasis of matter paragraph

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affected by conditions and events that cast substantial doubt on the Company's ability to continue as a going concern, such as those described in Note 1 to these interim unaudited consolidated financial statements. IFRS do not permit a reference to such events and conditions in the auditors' report when these are adequately disclosed in the financial statements. The Company draws attention to Note 1 to these financial statements, which describes certain conditions that give rise to substantial doubt about the entity's ability to continue as a going concern. However, these financial statements do not include any adjustments that might result from the outcome of this uncertainty consistent with the audited consolidated financial statements for the year ended December 31, 2010 whereby the Auditor's opinion was not qualified in respect of this matter.

ii.: Joint Venture

San Diego Joint Venture has been recorded under IFRS on a proportionate basis whereas under United States GAAP, investments in incorporated joint ventures should be accounted for using the equity method. However, the Company has elected to use the accommodation of the SEC whereby the accounting for joint ventures need not be reconciled from IFRS to United States GAAP since the different accounting treatment affects only the presentation and classification of financial statement items and not net income or shareholders' equity..

iii.: Accounts receivable



Value added tax recoverable	1,108,018	1,077,878	661,311
Trade receivables	25,562	357,320	125,171
Other receivables	293,872	190,284	277,515

	1,427,452	1,625,482	1,063,997

iv.: A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:



Canadian tax purposes
Opening balance	8,358,927		5,692,955
Increases based on tax positions related to the current year	1,850,960		2,665,972

	10,209,887		8,358,927

Mexican tax purposes
Opening balance	45,026,853		32,343,850
Increase (decrease) based on tax positions related to the current year	(5,460,166	)	12,683,003

v.: Income tax uncertainty

The Company and its subsidiaries file federal income tax returns in Canada and Mexico; the Company's Mexican subsidiaries also file Mexican state tax returns where required by law. With few exceptions, the Company and its Mexican subsidiaries are subject to Canadian federal or Mexican federal, state and local examinations by the tax authorities for a minimum of four years in arrearage to the extent that the Company receives a notice of assessment from the respective competent authorities.

iv.: Deferred income tax

IFRS financial statements do not take into account the tax benefit arising from loss carry forwards which are available to the Company to reduce its income for tax purposes in future periods so that no deferred income tax has been recorded in these IFRS financial statements. Deferred tax assets are not recognized for the tax benefit arising from loss carry forwards to the extent that it is not probable that taxable profits will be available against which these loss carry forwards can be utilized in the future. The Company has disclosed its non-capital loss carry forwards and tax loss carry forwards as at December 31, 2010 in Note 19, "Loss carry forwards" to these interim unaudited consolidated financial statements. Therefore, consistent with the current IFRS accounting treatment, no deferred income tax consequences have been recorded under United States GAAP relating to US GAAP adjustments recorded in the reconciliations forthwith.

Management's Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934 (United States) and Canadian securities regulations, for ECU Silver Mining Inc. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with generally accepted accounting principles.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Also, projections of the effectiveness of internal control are subject to the risk that the controls may become inadequate because of changes in conditions. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to the financial statement preparation and presentation.

Management carried out an evaluation of the effectiveness of internal control over financial reporting as of December 31, 2010. The framework on which such evaluation was based is contained in the report entitled Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Although there are inherent limitations in the effectiveness of any system of internal control over financial reporting, based on this evaluation, management has concluded that the system of internal control over financial reporting was effective as of December 31, 2010.

Guimond Lavallée Inc, our independent registered public accounting firm, has issued an attestation report on the effectiveness of internal control over financial reporting at ECU Silver Mining Inc. as at December 31, 2010, which is presented hereinafter.

Independent Auditor's Report

To the Shareholders of ECU Silver Mining Inc.,

We have completed integrated audits of ECU Silver Mining Inc's. (the Company) 2010 and 2009 consolidated financial statements and of its internal control over financial reporting as of December 31, 2010. Our opinions, based on our audits, are presented below.

Report on the consolidated financial statements

We have audited the accompanying consolidated financial statements of ECU Silver Mining Inc., which comprise the consolidated balance sheets as at December 31, 2010 and 2009 and the consolidated statements of loss, comprehensive loss and deficit and cash flows for the years then ended, and a summary of significant accounting policies and other explanatory information.

Management's responsibility for the consolidated financial statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with Canadian generally accepted accounting principles and for such internal control as management determines necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor's responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform an audit to obtain reasonable assurance whether the consolidated financial statements are free of material misstatement. Canadian generally accepted auditing standards require that we comply with ethical requirements.

An audit involves performing procedures to obtain audit evidence, on a test basis, about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risks assessments, the auditor considers internal control relevant to the Company's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances. An audit also includes evaluating the appropriateness of accounting principles and policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our opinion on the consolidated financial statements.

Opinion

In our opinion, the amended consolidated financial statements present fairly, in all material respects, the financial position of ECU Silver Mining Inc. as at December 31, 2010 and 2009 and the results of its operations and its cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.

Emphasis of Matter

Without modifying our opinion, the consolidated financial statements for the years ended December 31, 2010 and 2009 have been amended as disclosed in note 20 to the consolidated financial statements. Our report dated March 29, 2011 on the previously issued consolidated financial statements for the years ended December 31, 2010 and 2009 has been amended, as such.

Report on internal control over financial reporting

We have also audited ECU Silver Mining Inc. internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission.

Management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's report on Internal Control over Financial Reporting.

Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on assessed risk and performing such other procedures as we considered necessary in the circumstances.

We believe that our audit provides a reasonable basis for our audit opinion on the Company's internal control over financial reporting.

A Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A Company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, ECU Silver Mining Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2010 and 2009
(in Canadian dollars unless otherwise noted)

1. NATURE OF ACTIVITIES

ECU Silver Mining Inc. ("ECU", or the "Company") is engaged in the acquisition, exploration and development of mining properties in Mexico that are mainly gold-bearing and silver-bearing. The Company has earned revenues from its exploration and development activities and is considered to be in the development stage. It has not yet determined whether a sufficient proportion of its mineral resources are economically exploitable and, accordingly, has not yet determined whether the mining properties contain economic mineral reserves.

2. SIGNIFICANT ACCOUNTING POLICIES

These consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles. The significant accounting policies followed by the Company are summarized as follows:

a) Basis of Presentation

The consolidated financial statements include the accounts of the Company and those of its subsidiaries, all owned by ECU, BLM Minera Mexicana S.A de C.V., Minera William S.A de C.V., and Minera Labri S.A. de C.V., and on a proportionate basis, the accounts of the San Diego Joint Venture. All inter-company transactions and balances have been eliminated.

b) Use of Estimates

The preparation of financial statements in accordance with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and notes to consolidated financial statements. Significant areas where management's judgement has been applied include; the useful life of capital assets, the estimated net realizable value of inventory, asset impairment, stock-based compensation, and future income tax assets and liabilities. While management believes that these estimates and assumptions are reasonable, actual results could vary significantly.

c) Revenue recognition

As the Company is in the development stage, all revenues are offset against mining properties and deferred exploration costs in accordance with the recommendations of the section 3061 "Property, Plant and Equipment".

d) Foreign Exchange

The Canadian dollar is the functional currency of the Company. The Company uses the temporal method to translate its foreign currency transactions, including its integrated foreign subsidiaries. Monetary assets and liabilities are translated at the rate of exchange in effect at period-end. Other assets and liabilities are translated at their historic rates. Items appearing in the income statement, except for depreciation translated at historic rates, are translated at average rates. Exchange gains and losses are included in the income statement.

e) Cash and cash equivalents

The Company's policy is to present cash and temporary investments having a term of three months or less from the acquisition date with cash and cash equivalents.

h) Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is provided for plant and equipment on a straight-line basis over the estimated useful lives of the related assets and deferred to mining properties or charged to expense as appropriate. The following estimated useful lives are being used:


	Buildings		20 years
	Leasehold improvements		2 or 8 years
	Automotive		4 years
	Machinery and equipment		10 years
	Computer equipment		3¹/3 years
	Office equipment		10 years

i) Asset retirement obligations

The Company records the present value of its legal obligations associated with the asset retirement when the liability is incurred. The corresponding amount is capitalized as part of the related mining property's carrying value. While the associated mining property is in the pre-production stage, the liability is accreted over time through periodic charges to mining property costs. In each subsequent period, the carrying amounts of the asset and the liability are adjusted for changes to the Company`s estimate of future cash flows associated with the retirement obligations.

Management estimates that the current present value of legal obligations for asset retirement is de minimis.

j) Income and Mining Taxes

The Company uses the liability method to account for income taxes. Under this method of Section 3465, future tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax assets and liabilities are measured by using

enacted or substantively enacted tax rates expected to apply to taxable income in the years during which those temporary differences are expected to be recovered or settled. Under Section 3465, the effect on future tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

k) Basic and Diluted Loss per Share

l) Stock-based compensation

m) Financial Instruments

All financial assets and financial liabilities are classified as either: held-for-trading, available-for-sale, held-to-maturity, loans-and-receivables or other liabilities. Financial assets classified as held-for-trading or available-for-sale, are measured at fair value. Held-to-maturity, and loans-and-receivables are measured initially at fair value then at amortized cost over their term. Financial liabilities are measured at their fair value when they are classified as held-for-trading otherwise they are measured at amortized cost over their term. Initial differences between fair value and maturity value are amortized using the effective interest method.

Holding gains and losses from available-for-sale assets are included in other comprehensive income until realized at which time they are transferred to net income (loss).

Transaction costs such as arrangement and advance fees charged by the Company's principal lender in connection with long term debt are expensed at the time they are incurred.

n) Adoption of International Financial Reporting Standards

The Canadian Institute of Chartered Accountants has announced that publicly accountable enterprises will be required to adopt International Financial Reporting Standards ("IFRS") effective January 1, 2011. At the effective date, the balance sheet as at January 1, 2010 will require conversion to IFRS to establish opening balances which will form the basis for comparative information to be reported in 2011. Accordingly, this is the last set of financial statements for the Company using pre-IFRS.

4. INVENTORY

The Company has reflected its gold pyrite material-in-process inventory at a net realizable value of zero. During the first quarter of 2010, this resulted in the Company recording a write-down of inventory of $141,938. During the third quarter, the Company entered into a sales contract for a portion of its unprocessed gold pyrite concentrate inventory. In relation to the pyrite concentrate which was shipped during the year under the sales contract, the Company has recorded a reversal of the costs previously written off amounting to $2,045,613. This reversal has increased deferred mining costs with the offsetting amount recorded as a gain on reversal of inventory write-down.

5. MINING PROPERTY COSTS AND PROPERTY, PLANT AND EQUIPMENT (Continued)

Deferred costs for the Velardeña property have been offset by the related revenues. During the year total of such revenues was $19,345,686 ($6,577,167 — 2009). The cumulative amount of such revenues for the Velardeña property is $37,423,996 ($18,078,310 — 2009).

Chicago

The Chicago property is located approximately 2 km south of the Velardeña property. The property consists of 8 contiguous mineral concessions totalling 315.88 hectares. The Company has full title to the claims. The Company was actively mining on the property and processing the mined material at its mills situated near the town of Velardeña.

San Diego

The San Diego property is located 9 km northeast of ECU's Velardeña property. It is comprised of 4 contiguous mineral concessions totalling an area of 91.65 hectares and is being explored under the terms of a joint venture agreement in which the costs are shared 50/50 (See note 18). No exploration activity was undertaken in the period.

Nazas

The Nazas property is located approximately 64 km west of ECU's Velardeña property, within the municipality of Nazas, Durango State. The Company does not own the claims but is studying areas within the property under the terms of an agreement which will allow it to purchase the claims through a series of instalment payments at the Company's option.

Flechas

The Flechas project is located between the states of Durango and Zacatecas in the municipality of Santa Clara, Durango. It is located approximately 75.5 km southeast of the Company?s Oxide Mill and 20 km northeast of the Santa Clara town. It consists of a block of four mining concessions covering 948.52 hectares. Agreements are in place with the surface owners to conduct exploration and mining operations.

Presentation

The prior year's figures have been changed to correct for an error in the allocation of the cost of acquiring certain mineral concessions as between properties. The effect of the change is to increase the acquisition costs for the San Diego property by $205,080 and decrease the acquisition costs for the Velardeña property by $205,080. This change has no effect on the balance of mining properties in total.

Term loan

As at year end the Company owed $16,528,801 ($16,618,541 US dollars) on its term loan. An extension to the existing facility was signed during the year, the terms of which call for principal repayments in equal monthly instalments for 12 months commencing January 31, 2011. Interest is payable quarterly and is calculated at the greater of 12% and 1-month London Interbank Offered Rate plus 6%. The effective rate of interest on the loan is 12.8%. The loan is secured by a first mortgage covering certain of the current mining properties of the Company's Mexican subsidiaries, as well as the current and future facilities constructed thereon.

During the year the Company began negotiations with its lender to restructure the debt, and subsequent to year end, the restructuring was completed. Principal repayments under the amended facility are payable in thirty equal monthly payments commencing July 31, 2011 and ending December 31, 2013. The terms of interest payable under the restructured facility were unchanged. The statements reflect the effect of the restructuring which was to reduce the current portion of the debt from $16,528,801 to $3,305,760 and to increase working capital by $13,223,041.

8. SHARE CAPITAL (Continued)

In the prior year, the Company completed an offering of 16,946,000 special warrants (the "Special Warrants") to subscribers on a private placement basis at a price of $0.72 per Special Warrant for a total gross proceeds of $12,201,120. The net proceeds of the issue of $10,801,114 were reflected in a separate category in Shareholders' Equity at December 31, 2009.

In December 2010, the Company received proceeds for the exercise of the 300,000 stock options recorded. The related share issuance was completed by the Company's registrar in January 2011.

9. STOCK OPTIONS

During the year the Company granted 100,000 stock options with an estimated fair value of $34,974 to an officer of the Company. The Company reflected $26,230 of the fair value as mining property costs during the period with contributed surplus increased by the same amount. On November 15, 2010, 25,000 of the options were cancelled and as result the remainder of the fair value will not be recognized. The exercise price of the options granted was greater than the market price at the date of grant. The fair value of stock options issued was estimated at the grant date based on the Black-Scholes option pricing model using the following weighted average assumptions:



Risk-free interest rate	2.3%	2.3%
Expected life (years)	3.0	4.0
Expected volatility	65%	66%
Expected dividend yield	nil	nil

bound to issue an additional 500,000 common shares should it choose to use the technology at a commercial scale. In addition, the agreement provides that the Company pay royalties of 1.5% of all production resulting from the application of the technology in Mexican properties. The technology was not employed in the current period.

Arbitration

During the year, the Company completed the arbitration hearing held pursuant to a Notice of Arbitration, received June 23, 2009 from Golden Tag wherein Golden Tag sought to refer certain matters, pertaining to the operation of the joint venture, to arbitration for resolution. On September 20, 2010 the Arbitration Panel rendered their conclusion in the matter. The Company finds the award of the arbitration panel ("Arbitration Award") to be fair and has settled the matter with Golden Tag.

The conclusions reached in the Arbitration Award have resulted in an increase in the Velardeña mining property costs of $61,171 related to cost of material from the joint venture property processed in the Company's plant.

15. EXPLANATORY NOTE FOR CONSOLIDATED STATEMENT OF CASH FLOWS

Within the grouping Investment Activities, the amount of $2,487,037, stated as the cash expenditure on mining property acquisition costs, includes an amount of $2,331,600 which reflects a cash expenditure made under the terms of the contracts described under Mineral concession liability in note 7.

16. MANAGEMENT OF CAPITAL

As at December 31, 2010, the Company had long-term debt of $16,618,541 US dollars, repayment of which was scheduled to commence January 31, 2011. In January 2011, the Company restructured the facility with its lender. Principal repayments under the amended facility are payable in thirty equal monthly payments commencing July 31, 2011 and ending December 31, 2013.

The Company is also obligated to semi-annual payments of $1,000,000 US dollars due under terms of a mineral concession agreement.

Based on current plans and estimates management believes that its operations can be funded through working capital, potential future credit facilities, and cash flow expected to be generated from the sale of products from its operations. As discussed note 1, the Company is dependent on its ability to raise the necessary capital to fund its operations and management can not provide assurance that it will ultimately be able to complete the required funding transactions. Furthermore, since we do not have proven and probable reserves we can not predict with confidence the level of cash flows that will be generated from the new mill. As such, we may need to either restructure our long term debt so that repayment requirements match the cash generation capability or raise additional equity in the alternate. Management can provide no guarantee that the Company will be successful in these transactions should they be required.

Notes to consolidated United States GAAP adjustments:

a. Mining property costs

Under Canadian GAAP, costs of acquiring mineral properties and related development expenditures are deferred. Exploration costs on mineral properties, other than acquisition costs, are deferred and capitalized under Canadian GAAP prior to the establishment of proven or probable reserves if they are considered to meet the definition of an asset. United States GAAP requires that all exploration costs be expensed.

b. Inventories

The Company has reflected its gold pyrite material-in-process inventory at a net realizable value of zero and, as such, recorded write-downs of inventory and an expense in the statement of loss. Under Canadian GAAP, the Company subsequently recorded a reversal of those write offs at the point where sales contracts for the related inventory were put in place. United States GAAP does not permit the reversal of previous write-downs of inventory.

c. Mining property costs classification in other income

Under Canadian GAAP, net revenue or expense derived from a mineral property prior to the production phase of a mine is capitalized and included in the cost of the asset. A United States GAAP adjustment arises because United States GAAP requires that all exploration related costs and associated revenues be expensed. Furthermore, United States GAAP requires that any incremental and direct costs associated with the sale of excavated saleable minerals during the development phase of the mine and prior to the production phase of the mine be classified as Other income and offset by the related amounts of proceeds from the sale

of these minerals. Incremental and direct costs are those costs that would otherwise have not been incurred if not for the sale of these minerals.

d. Stock-based compensation and stock options

Under Canadian GAAP, stock-based compensation costs and stock option costs incurred during the exploration or development stage of the mineral properties are deferred and capitalized prior to the establishment of proven or probable reserves if they are considered to meet the definition of an asset. United States GAAP requires that all stock-based compensation costs and stock option costs be expensed.

e. Convertible debentures

Under Canadian GAAP, convertible debenture proceeds are allocated between their debt and equity component parts based on the relative fair values of the debt component and the embedded conversion feature. The debt component is accreted to the face value of the debentures with the resulting interest expense charged to operations. The costs of the financing are allocated on a proportional basis between the liability and equity portions based on their relative fair values with the liability portion of the costs expensed and the equity portion treated as a reduction of the gross proceeds allocated to the equity component. United States GAAP treats the convertible debenture solely as a liability since the embedded conversion feature does not meet US GAAP requirements for classification as an equity component. The liability is recorded at its full face value since the embedded conversion feature has no intrinsic value on a stand-alone basis and accordingly does not meet the requirements of an equity component under United States GAAP. United States GAAP requires that convertible debentures, net of issuance costs, be accreted to face value over the term ending on the first put date of the debentures which, in this case, is the issuance date of the debentures since the debentures are convertible on demand by the Unit holders. Thus, the debentures' carrying value equals their face value on the balance sheet.

f. Mining property costs classification in statement of cash flow

United States GAAP requires that cash flows relating to mineral property exploration and land use costs be reported as operating activities. However, under Canadian GAAP mineral property exploration and land use costs are classified as investing activities.

g. Restricted cash

Under Canadian GAAP, restricted cash was disclosed as a separate line item in the statement of cash flows. United States GAAP requires that restricted cash be disclosed as a financing activity.

Other disclosures:

The following additional information would be presented if these consolidated financial statements were presented in accordance with U.S. GAAP:

i.: Auditor's Report: Emphasis of matter paragraph

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affected by conditions and events that cast substantial doubt on the Company's ability to continue as a going concern, such as those described in Note 1 to the financial statements. Canadian reporting standards do not permit a reference to such events and conditions in the auditors' report when these are adequately disclosed in the financial statements. The Auditor draws attention to Note 1 to the financial statements, which describes certain conditions that give rise to substantial doubt about the entity's ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Auditor's opinion is not qualified in respect of this matter.

ii.: Joint Venture

San Diego Joint Venture has been recorded under Canadian GAAP on a proportionate basis whereas under United States GAAP, investments in incorporated joint ventures should be accounted for using the equity method. However, the Company

has elected to use the accommodation of the SEC whereby the accounting for joint ventures need not be reconciled from Canadian GAAP to United States GAAP since the different accounting treatment affects only the presentation and classification of financial statement items and not net income or shareholders' equity.

iii.: Accounts receivable



Value added tax recoverable	1,077,878	661,311
Trade receivables	357,320	125,171
Other receivables	190,284	277,515

	1,625,482	1,063,997

iv.: A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:



Canadian tax purposes
Opening balance	8,358,927		5,692,955
Increases based on tax positions related to the current year	1,850,960		2,665,972

	10,209,887		8,358,927

Mexican tax purposes
Opening balance	45,026,853		32,343,850
Increases (decrease) based on tax positions related to the current year	(5,460,166	)	12,683,003

	39,566,687		45,026,853

v.: Income tax uncertainty

vi.: Deferred income tax

Canadian GAAP financial statements do not take into account the tax benefit arising from loss carry forwards which are available to the Company to reduce its income for tax purposes in future periods so that no deferred income tax has been recorded in the Canadian GAAP financial statements. Deferred tax assets are not recognized for the tax benefit arising from loss carry forwards to the extent that it is not probable that taxable profits will be available against which these loss carry forwards can be utilized in the future. The Company has disclosed its non-capital loss carry forwards and tax loss carry forwards as at December 31, 2010 in Note 19, "Loss carry forwards" to these consolidated financial statements. Therefore, consistent with the current Canadian GAAP accounting treatment, no deferred income tax consequences have been recorded under United States GAAP relating to US GAAP adjustments recorded in the reconciliations forthwith.

Independent Auditor's Report

To the Shareholders of ECU Silver Mining Inc.,

We have completed an integrated audit of ECU Silver Mining Inc. (the Company) 2009 and 2008 consolidated financial statements and of its internal control over financial reporting as of December 31, 2009. Our opinions, based on our audits, are presented below.

Consolidated Financial statements

We have audited the consolidated balance sheets of ECU Silver Mining Inc. as at December 31, 2009 and 2008 and the consolidated statements of loss, comprehensive loss and deficit, and cash flows for the years then ended, and a summary of significant accounting policies and other explanatory information. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits of the Company's consolidated financial statements in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform an audit to obtain reasonable assurance whether the consolidated financial statements are free of material misstatement. An audit of consolidated financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. A consolidated financial statements audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, these amended consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2009 and 2008 and the results of its operations and its cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.

Without modifying our opinion, the consolidated financial statements for the years December 31, 2009 and 2008 have been amended as disclosed in note 24 to the consolidated financial statements. Our report dated March 30, 2010 on the previously issued consolidated financial statements for the years ended December 31, 2009 and 2008 has been amended as such.

Internal control over financial reporting

We have also audited the Company's internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on assessed risk and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A Company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of

D-55

Table of Contents

consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the consolidated financial statements.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for the years ended December 31, 2009 and 2008
(in Canadian dollars unless otherwise noted)

1. NATURE OF ACTIVITIES

These consolidated financial statements have been prepared on a going concern basis, which assumes that the company will, in the ordinary course of business, be able to realize its assets and discharge its liabilities. The recoverability of the accumulated costs shown for mining properties and related deferred costs is dependent upon the existence of economically recoverable reserves, future profitable production, and on the Company's ability to obtain the necessary financing to fund its operations.

2. SIGNIFICANT ACCOUNTING POLICIES

a) Basis of Presentation

b) Use of Estimates

c) Revenue recognition

As the Company is in the development stage, all revenues are offset against mining properties and deferred exploration costs in accordance with the recommendations of the Emerging Issues Committee, EIC 27 "Revenues and Expenditures During the Pre-operating Period".

d) Foreign Exchange

The Canadian dollar is the functional currency of the Company. The Company uses the temporal method to translate its foreign currency transactions, including its integrated foreign subsidiaries. Monetary assets and liabilities are translated at the rate of exchange in effect at period-end. Other assets and liabilities are translated at their historic rates. Items appearing in the income statement, except for depreciation translated at historic rates, are translated at average year rates. Exchange gains and losses are included in the income statement.

e) Cash and cash equivalents

The Company's policy is to present cash and temporary investments having a term of three months or less from the acquisition date with cash and cash equivalents.

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

f) Inventory

Materials-in-process (concentrates) are valued at lower of average production cost and net realizable value.

g) Mining Properties, and Deferred Exploration and Development Expenses

On a periodic basis, senior management reviews the carrying values of mining properties and deferred exploration expenditures with a view to assessing whether there has been any impairment in value. In the event that it is determined there is an impairment in the carrying value of any property, the carrying value will be written down or written off, as appropriate. There was no impairment write-down required at December 31, 2009.

Supplies and spare parts are valued at the lower of average cost and replacement cost.

h) Property, Plant and Equipment


	Buildings		20 years
	Leasehold improvements		2 or 8 years
	Automotive		4 years
	Machinery and equipment		10 years
	Computer equipment		3¹/3 years
	Office equipment		10 years

i) Asset retirement obligations

The Company records the present value of its legal obligations associated with the asset retirement when the liability is incurred. The corresponding amount is capitalized as part of the related mining property`s carrying value. While the associated mining property is in the pre-production stage, the liability is accreted over time through periodic charges to mining property costs. In each subsequent period, the carrying amounts of the asset and the liability are adjusted for changes to the Company's estimate of future cash flows associated with the retirement obligations.

Management estimates that the current present value of legal obligations for asset retirement is de minimis.

j) Income and Mining Taxes

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

k) Basic and Diluted Loss per Share

l) Stock-based compensation

Stock options granted to employees and non-employees are accounted for using the fair value method. Under this method, the compensation cost is measured as at the date of the grant by applying the Black-Scholes option pricing model. The determined fair value is recognized as a cost over the vesting period with a corresponding increase to contributed surplus. On the exercise of stock options, consideration paid and the associated contributed surplus is credited to common shares.

m) Financial Instruments

Holding gains and losses from available-for-sale assets are included in other comprehensive income until realized at which time they are transferred to net income (loss).

Transaction costs such as arrangement and advance fees charged by the Company's principal lender in connection with long term debt are expensed at the time they are incurred.

3. ADOPTION OF NEW ACCOUNTING POLICIES

Effective January 1, 2009, the Company adopted the following new accounting standards issued by the Canadian Institute of Chartered Accountants:

(i): Section 3064, Goodwill and Intangible Assets

The standard reinforces the principle-based approach to the recognition of assets only in accordance with the definition of an asset and the criteria for asset recognition; and clarifies the application of the concept of matching revenues and expenses such that the current practice of recognizing assets that may not meet the definition and recognition criteria are eliminated. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

(ii): EIC-173, Credit Risk and the Fair Value of Financial Assets and Financial Liabilities

The standard provides guidance on how to take into account credit risk of an entity and counterparty when determining the fair value of financial assets and financial liabilities, including derivative instruments. Adoption of this Abstract did not have any effect on the Company's consolidated financial statements.

(iii): EIC-174, Impairment Testing of Mineral Exploration Properties

This standard recommends the analysis be performed to determine if there has been an impairment of mineral exploration properties. The Company implemented the recommendations discussed in this Abstract when testing for impairment of mineral

exploration properties in the period. Adoption of this standard did not have any effect on the Company's consolidated financial statements.

(iv): Section 3862, Amendment to Financial Instruments — Disclosures

This section was amended to improve financial instrument disclosures to include additional disclosure requirements about fair value measurement for financial instruments and liquidity risk disclosures. The impact of adopting these amendments for the year ended December 31, 2009 did not result in additional disclosures included within these consolidated financial statements.

5. INVENTORY

The Company has reflected its gold pyrite material-in-process inventory at a net realizable value of zero. As such, it has recorded a write-down of inventory of $844,064 ($827,384 — 2008). Management believes that it can optimize the value of the gold pyrite material with further treatment of the material. The method we intend to use for further processing has been determined and the equipment and infrastructure for doing so is in place. We are currently in the process of testing the consistency of the equipment and running batch treatment tests of the gold/pyrite material. We are also evaluating and considering a sales contract for the processed material. The inventory will be reflected at a net realizable value of zero until such time as the processing method has been proven and the sales contracts are in place.

12. SPECIAL WARRANTS

On December 9, 2009 (the "Closing Date"), the Company issued 16,946,000 special warrants (the "Special Warrants") to subscribers ("Subscribers") on a private placement basis at a price of $0.72 per Special Warrant (the "Private Placement") for a total gross proceeds of $12,201,120. The net proceeds of the issue of $10,801,114 have been assigned to a separate category in Shareholder's Equity.

Each Special Warrant entitles the holder thereof to receive, without the payment of additional consideration, one unit (the "Unit") on the exercise or deemed exercise of the Special Warrant. Each Unit is comprised of one common share in the share capital of the Company (a "Special Warrant Share") and one-half of one warrant to purchase a common share in the share capital of the Company (each whole warrant, a "Purchase Warrant", and together with the Special Warrant Shares, the "Qualified Securities"). Each Purchase Warrant will entitle the holder thereof to purchase one common share in the share capital of the Company (a "Purchase Warrant Share") at an exercise price of $0.90 per Purchase Warrant Share at any time before December 9, 2011.

Each Special Warrant will be deemed to be exercised and surrendered, without any further action by the holder thereof, on the earlier of: (a) the third business day after the date (the "Prospectus Qualification Date") that a final receipt is issued for this short form prospectus by the securities regulatory authority of the province in which such holder is resident (or by the Autorité des marchés financiers if the holder is not a resident of Canada); and (b) April 10, 2010 (the "Conversion Deadline"). If the Prospectus Qualification Date does not occur on or before January 23, 2010 (the "Qualification Deadline"), then each Special Warrant exercised or deemed to be exercised following the Qualification Deadline shall entitle its holder to acquire 1.1 Units (1.1 Special Warrant Shares and 0.55 Purchase Warrants).

Subsequent to year end, on January 22, 2010, the final receipt for the short form prospectus was received and all the outstanding Special Warrants were deemed to be exercised effective January 27, 2010.

13. STOCK OPTIONS

During the year the Company granted 150,000 stock options with an estimated fair value of $21,000 in respect of investor relations activities, 150,000 stock options with an estimated fair value of $58,575 in respect of investment promotion activities, and 2,820,000 stock options with an estimated fair value of $1,101,203 to directors and officers. The Company reflected $247,157 of these fair values as compensation expense and as mining property costs during the year with contributed surplus increased by the same amount. The remainder of the fair value will be recognized over the related vesting periods. The exercise price of each of the options granted was greater than the market price at the date of grant. The fair value of stock options issued was estimated at the grant date based on the Black-Scholes option pricing model using the following weighted average assumptions:



Risk-free interest rate	2.3%	3.2%
Expected life (years)	4.0	2.5
Expected volatility	66%	58%
Expected dividend yield	nil	nil

17. CONTINGENCIES (Continued)

Arbitration

On June 24, 2009, the Company received a Notice of Arbitration (the "Notice") from its San Diego Property joint venture partner, Golden Tag Resources Ltd. ("Golden Tag"), wherein Golden Tag is seeking to refer certain matters, pertaining to the operation of the joint venture, to arbitration for resolution. The Company intends to vigorously contest the Notice and the conclusions sought therein. The Company is not able at this time to predict the outcome of such action or to estimate the potential amount of any loss that may result from an unfavourable ruling.

19. EXPLANATORY NOTE FOR CONSOLIDATED STATEMENT OF CASH FLOWS

Within the grouping Investment Activities, the amount of $3,428,880, stated as the cash expenditure on mining property acquisition costs, includes the payment of $2,331,600 paid under the terms of the contracts described under Mineral concession liability in note 9.

Long term debt increased by $944,365 ($868,541 US Dollars) in a non-cash transaction as part of the debt restructuring in which interest payable under the terms of the debt was consolidated into the long term debt. See note 9 under Term loan.

20. MANAGEMENT OF CAPITAL

The Company's objectives in managing its capital resources are to ensure the entity's ability to continue as a going concern. The Company satisfies its capital requirements through careful management of its cash resources and by utilizing credit facilities or issuing equity, as necessary, based on the prevalent economic conditions of both the industry and the capital markets and the underlying risks characteristics of the related assets. As at December 31, 2009, the Company had long-term debt of $16,618,541 US Dollars, repayment of which commences November 2009. The Company is also obligated to semi-annual payments of $1,000,000 due under terms of a mineral concession agreement.

Based on current plans and estimates management believes that its operations can be funded through working capital, potential future credit facilities, and cash flow expected to be generated from the sale of the gold and silver doré bars generated from the new recovery plant. As discussed note 1, the company is dependent on its ability to raise the necessary capital to fund its operations and management can not provide assurance that it will ultimately be able to complete the required funding transactions. Furthermore, since we do not have proven and probable reserves we can not predict with confidence the level of cash flows that will be generated from the new mill. As such, we may need to either restructure our long term debt so that repayment requirements match the cash generation capability or raise additional equity in the alternate. Management can provide no guarantee that the Company will be successful in these transactions should they be required.

The Company is not subject to any externally imposed capital requirements and there has been no change with respect to the overall capital risk management strategy during the year.

21. FINANCIAL INSTRUMENTS

The Company's financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, advances and deposits, accounts payable and accrued liabilities, promissory notes payable, customer advances and long-term debt. Cash and cash equivalents are recognized at their fair value and the fair value of all other financial instruments approximate their carrying values, either due to

their short-term maturity or capacity of prompt liquidation or, in the case of long-term debt because the market rate of interest is paid. Cash and cash equivalents are held with large financial institutions and, as at December 31, 2009 did not include any investments in asset-backed commercial paper.

The Company operates in Mexico and is exposed to currency risk in the normal course of business. Its sales and related accounts receivable are denominated in US dollars. A significant portion of its expenditures and related accounts payable are denominated in US dollars and Mexican pesos. The Company's long-term debt is denominated in US dollars. A portion of its cash and cash equivalents are held in US dollars and Mexican pesos.

22. SAN DIEGO — JOINT VENTURE

The Company's consolidated financial statements include the following amounts related to the San Diego Joint Venture:



Long term assets
	Mining property costs	747,416		686,540
Cash flows resulting from investing activities
	Mining property costs	(60,876	)	(726,808	)

ECU's share in the joint venture with Golden Tag Resources Ltd ("Golden Tag") is 50% of the mining property costs incurred following the US$1,500,000 earn in by Golden Tag. The share was capitalized under Mining Properties for a value in the current year of $66,464 less project management fees charged to Golden Tag of $5,588.

23. LOSS CARRY FORWARDS

These financial statements do not take into account the tax benefit arising from loss carry forwards which are available to the Company to reduce its income for tax purposes in future periods.

At December 31, 2009, the Company had non-capital loss carryforwards, available to offset future taxable income for Canadian tax purposes, aggregating $8,358,927 which expire over the period between 2010 and 2029.

Notes to consolidated United States GAAP adjustments:

a. Mining property costs

b. Inventories

The Company has reflected its gold pyrite material-in-process inventory at a net realizable value of zero and, as such, recorded write-downs of inventory and an expense in the statement of loss. Under Canadian GAAP, the Company subsequently recorded a reversal of those write offs at the point where sales contracts for the related inventory were concluded. United States GAAP does not permit the reversal of previous write-downs of inventory.

c. Mining property costs classification in other income

of these minerals. Incremental and direct costs are those costs that would otherwise have not been incurred if not for the sale of these minerals.

d. Stock-based compensation and stock options

e. Convertible debentures

f. Mining property costs classification in statement of cash flow

g. Restricted cash

Under Canadian GAAP, restricted cash was disclosed as a separate line item in the statement of cash flows. United States GAAP requires that restricted cash be disclosed as a financing activity.

Other disclosures:

The following additional information would be presented if these consolidated financial statements were presented in accordance with U.S. GAAP:

i.: Auditor's Report: Emphasis of matter paragraph

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affected by conditions and events that cast substantial doubt on the Company's ability to continue as a going concern, such as those described in Note 1 to the financial statements. Canadian reporting standards do not permit a reference to such events and conditions in the auditors' report when these are adequately disclosed in the financial statements. The Auditor draws attention to Note 1 to the financial statements, which describes certain conditions that give rise to substantial doubt about the entity's ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Auditor's opinion is not qualified in respect of this matter.

ii.: Joint Venture

v.: Income tax uncertainty

vi.: Deferred income tax

Canadian GAAP financial statements do not take into account the tax benefit arising from loss carry forwards which are available to the Company to reduce its income for tax purposes in future periods so that no deferred income tax has been recorded in the Canadian GAAP financial statements. Deferred tax assets are not recognized for the tax benefit arising from loss carry forwards to the extent that it is not probable that taxable profits will be available against which these loss carry forwards can be utilized in the future. The Company has disclosed its non-capital loss carry forwards and tax loss carry forwards as at December 31, 2009 in Note 23, "Loss carry forwards" to these consolidated financial statements. Therefore, consistent with the current Canadian GAAP accounting treatment, no deferred income tax consequences have been recorded under United States GAAP relating to US GAAP adjustments recorded in the reconciliations forthwith.

Annex E

UNAUDITED PRO FORMA, COMBINED, CONDENSED
FINANCIAL INFORMATION OF GOLDEN MINERALS COMPANY

The following unaudited pro forma combined condensed financial information as of March 31, 2011, for the three-month period then ended and for the fiscal year ended December 31, 2010 is presented to show the results of operations of Golden Minerals as if the Transaction with ECU had occurred as of January 1, 2010, and financial position as if the Transaction had occurred as of March 31, 2011.

This unaudited pro forma combined condensed financial information should be read in conjunction with the selected historical financial information and related financial statements and accompanying footnotes of ECU included in this Circular and the financial statements and accompanying notes of Golden Minerals that are incorporated by reference into this Circular. You should not rely on the unaudited pro forma combined condensed financial information as an indication of the results of operations or financial position that would have been achieved if the Transaction with ECU had taken place on the dates indicated or an indication of the results of operations in the future.

The following Unaudited Pro Forma Combined Condensed Financial Data consists of an Unaudited Pro Forma Combined Condensed Balance Sheet as of March 31, 2011 for Golden Minerals and ECU and Unaudited Pro Forma Condensed Statements of Operations and Comprehensive Income for the three-months ended March 31, 2011 and for the year ended December 31, 2010 (collectively, the "Pro Forma Statements"). ECU's historical financial statements were prepared in accordance with Canadian GAAP at December 31, 2010 and in accordance with International Financial Reporting Standards ("IFRS") at March 31, 2011. Both methods of preparation differ in certain respects from U.S. GAAP. ECU Silver Mining's historical financial statements were also reported in Canadian dollars. ECU's historical financial statements used in these Pro Forma Statements have been adjusted to conform to U.S. GAAP and have been translated to U.S. dollars. ECU's historical financial statements were translated to U.S. dollars using period ending exchange rates of $0.995 and $0.972 for the condensed consolidated balance sheets at December 31, 2010 and March 31, 2011, respectively and average exchange rates of $1.030 and $0.986 for the condensed consolidated statements of operations for the year ended December 31, 2010 and the three-months ended March 31, 2011, respectively. The principal GAAP differences relate to: 1) the treatment of exploration and development costs and 2) revenues generated from saleable minerals during the development stage. Under Canadian GAAP and IFRS, ECU has been capitalizing exploration and development costs incurred during the development stage and offsetting those capitalized costs with revenue generated from saleable minerals. Under U.S. GAAP, those exploration and development costs would have appeared as expenses on the statement of operations and revenues generated during the development stage would have appeared as other income, net of incremental and direct costs associated with the revenue, on the statement of operations. The change to U.S. GAAP and U.S. dollars resulted in an increase in ECU's reported net losses of approximately $2.5 million for the fiscal year ended December 31, 2010 and in a decrease in ECU Silver Mining's reported net losses for the quarter ended March 31, 2011 of approximately $1.3 million. Golden Mineral's historical financial statements are prepared in accordance with U.S. GAAP.

The Pro Forma Statements reflect the terms of the Transaction, which will be structured as a plan of arrangement under the Québec Business Corporations Act, whereby each ECU share will be exchanged for 0.05 Golden Minerals shares and $0.000394 in cash. Upon completion of the Transaction, existing Golden Minerals shareholders and ECU shareholders will own approximately 49% and 51%, respectively, of the outstanding common stock of the combined company.

Golden Mineral's management believes that, on the basis set forth herein, the Pro Forma Statements reflect a reasonable estimate of the Transaction based on currently available information. Golden Minerals Company expects the Transaction to be accounted for as a business combination which requires the allocation of the purchase price to be based upon the estimated fair value of assets acquired and liabilities assumed. The actual purchase price may differ based on fluctuations in the price of Golden Mineral's common stock. See Note (1) in the unaudited pro forma financial statements for sensitivity analysis on the impact of fluctuations in the price of Golden Mineral's common stock and the purchase price.

Unaudited Pro Forma Combined Condensed Consolidated Statements of Operations (Continued)

For The Quarter Ended March 31, 2011

The following adjustments have been reflected in the Unaudited Combined Pro Forma Statements:

(1): To record the issuance of 16,004,067 shares of Golden Minerals common stock and $0.1 million of cash as purchase consideration for the Transaction based on an assumed March 31, 2011 closing. The preliminary allocation of the purchase price based on the estimated fair value of assets acquired and liabilities assumed is as follows:

Calculation of purchase price ($000's):


Cash consideration	$	126
Stock consideration(a)		250,464
Replacement stock options(b)		1,611
Replacement warrants(b)		12,130

Total purchase price	$	264,331

(a): The value of Golden Minerals common stock used in these pro forma calculations is $15.65, the closing price on July 27, 2011. The actual value of Golden Mineral's common stock will not be known until the Effective Date and may differ materially based on changes in share price through the Effective Date. A 10% increase in the value of Golden Mineral's common stock would result in an increase in the purchase price of approximately $25.0 million while a 10% reduction in the value of Golden Mineral's common stock would result in a decrease in the purchase price of approximately $25.0 million.
(b): Certain of ECU's outstanding stock options and warrants will be replaced with Golden Minerals stock options and warrants at quantities and at strike prices based on the Arrangement's ratio if 0.05 Golden Minerals shares for each ECU share. These options and warrants were obligations of ECU prior to the Transaction and are therefore considered a portion of the purchase price. The fair value of these options and warrants used in this calculation were determined using a Black-Scholes pricing model.

Preliminary allocation of purchase price ($000's):


Current assets(c)	$	2,843
Mineral properties(d)		273,354
Plant and equipment(e)		15,647
Liabilities assumed(c)		(9,008	)
Current portion of long term debt(c)		(6,880	)
Long term debt assumed(c)		(11,625	)

Total purchase price	$	264,331

(c): Monetary assets and liabilities assumed have been recorded at their carrying values, which approximate fair value.
(d): Mineral properties are recorded at estimated fair market value based on the value of the consideration given in the form of Golden Minerals common stock. The mineral properties will not be amortized as they currently have no proven and probable reserves.

Unaudited Pro Forma Combined Condensed Consolidated Statements of Operations (Continued)

For The Quarter Ended March 31, 2011

(e): Plant and equipment purchased in the Arrangement have been recorded at their carrying values, which approximate fair value.

(2): To record a deferred tax liability related to the taxable effect of the stepped-up basis in mineral properties recorded. The deferred tax liability was calculated by applying the Mexico corporate tax rate of 28% to the stepped-up basis in the mineral properties recorded and is net of a deferred tax asset of approximately $8.3 million resulting from the application of the 28% Mexico corporate tax rate to an estimated usable net operating loss carry-forward of approximately $29.5 million.
(3): To eliminate ECU's historical equity and non-monetary asset balances.
(4): The Pro Forma Combined Statement of Operations do not include estimated one-time transaction costs totaling $16.0 million. Total transaction costs consist of estimated one-time transaction costs of $5.0 million incurred by Golden Minerals and estimated one-time transaction costs including severance benefits, bonuses, and other change of control payments of $11.0 million incurred by ECU, a portion of which will be paid through the issuance of $2.8 million of Golden Minerals shares. The transaction costs will be recorded once the expenses have been incurred and may differ from the estimate.
(5): Upon completion of the Arrangement, existing Golden Minerals shareholders and ECU shareholders will own approximately 49% and 51%, respectively, of the outstanding common stock of the combined company. The transaction constitutes a change in control under the terms of Golden Mineral's 2009 Equity Incentive Plan and triggers the vesting of certain previously unvested stock grants to Golden Minerals officers and employees. The accelerated vesting of these stock grants would have resulted in the recognition of approximately $2.9 million of stock based compensation expense. This direct incremental cost is not included in the Unaudited Pro Forma Combined Statement of Operations but will be recorded to expense when the Arrangement with ECU is closed and may differ from the estimated amount herein.

CONFIDENTIAL

Board of Directors
Golden Minerals Company
350 Indiana Street, Suite 800
Golden, Colorado, 80401
U.S.A.

Ladies and Gentlemen:

You have requested that BMO Capital Markets Corp. ("BMOCM" or "we") render an opinion, as investment bankers, as to the fairness, from a financial point of view, to Golden Minerals Company, a Delaware corporation (the "Company"), of the Exchange Ratio (as defined below) specified in the proposed Arrangement Agreement (the "Arrangement Agreement") by and between ECU Silver Mining Inc. ("ECU") and the Company and the related Plan of Arrangement contemplated thereby (the "Plan of Arrangement"). Pursuant to the terms of and subject to the conditions set forth in the Arrangement Agreement and the Plan of Arrangement, shares of common stock of ECU shall be transferred and assigned by the stockholders of ECU to the Company (the "Arrangement"). Upon the effectiveness of the Arrangement, each outstanding share of common stock of ECU will be transferred and assigned to the Company in consideration for 0.05 of a share of common stock of the Company and C$0.000394 in cash (collectively, the "Exchange Ratio"), except for shares held by ECU shareholders as to which statutory dissenters' rights are properly exercised. For purposes of this opinion, we have reviewed a draft dated June 23, 2011 of the Arrangement Agreement and the Plan of Arrangement provided to us by the Company and have assumed that the final form of this agreement and plan will not differ in any material respect from the draft Arrangement Agreement and Plan of Arrangement provided to us.

We have assumed that all of the conditions to the Arrangement will be satisfied and that the Arrangement and related transactions will be consummated on the terms reflected in the Arrangement Agreement and the Plan of Arrangement, without waiver or amendment thereof.

In arriving at our opinion set forth below, we have, among other things:

(1): reviewed the draft Arrangement Agreement and Plan of Arrangement;
(2): reviewed a draft copy of the subscription agreement between the Company and ECU;
(3): reviewed internal management forecasts prepared by or on behalf of the Company and ECU;
(4): reviewed operating and financial forecasts for the Company provided by the management of the Company and operating and financial forecasts for ECU provided by ECU's management and adjusted by management of the Company;
(5): reviewed certain other internal information prepared by or on behalf of the Company;
(6): reviewed public information (including that prepared by industry research analysts) relating to the business, operations, and financial condition and trading history of the Company, ECU, and other selected public issuers we considered relevant;

F-1

Table of Contents

(7): reviewed letters of representation as to certain factual matters and the completeness and accuracy of the information upon which the opinion is based provided by senior officers of the Company;
(8): reviewed such other information, investigations, analyses and discussions as we considered necessary or appropriate in the circumstances;
(9): conducted discussions with members of senior management and representatives of the Company concerning the respective operations, financial condition and prospects of the Company and ECU;
(10): reviewed relevant financial contribution from both the Company and ECU to the merged entity;
(11): reviewed the pro forma impact of the Arrangement on the Company, based on assumptions relating to transaction expenses, and purchase accounting assumptions determined by senior management of the Company;
(12): reviewed historical stock prices of the common stock of the Company and ECU; and
(13): reviewed such other financial studies and performed such other analyses and investigations and took into account such other matters as we deemed appropriate.

In rendering our opinion, we have assumed and relied upon the accuracy and completeness of all information supplied or otherwise made available to us by the Company, ECU or their representatives or advisors or obtained by us from other sources. We have not independently verified (nor assumed any obligation to verify) any such information, undertaken an independent valuation or appraisal of the assets or liabilities (contingent or otherwise) of the Company or ECU, nor have we been furnished with any such valuation or appraisal. We have not evaluated the solvency or fair value of the Company or ECU under any state or federal laws relating to bankruptcy, insolvency or similar matters. With respect to financial projections, including estimated synergies, for the Company and ECU, we have been advised by the Company and ECU, and we have assumed, without independent investigation, that they have been reasonably prepared and reflect the best currently available estimates and good faith judgments of senior management of the Company and ECU (or, with respect to estimates and forecasts obtained from public sources, represent reasonable estimates and forecasts) of the expected future competitive, operating and regulatory environments and related financial performance of the Company and ECU. We express no opinion with respect to such projections, including estimated synergies, or the assumptions on which they are based. Furthermore, we have not assumed any obligation to conduct, and have not conducted, any physical inspection of the properties or facilities of the Company or ECU.

Our opinion is necessarily based upon financial, economic, market and other conditions and circumstances as they exist and can be evaluated, and the information made available to us, as of the date hereof. We disclaim any undertakings or obligations to advise any person of any change in any fact or matter affecting the opinion which may come or be brought to our attention after the date of the opinion.

Our opinion does not constitute a recommendation as to any action the Board of Directors of the Company or any stockholder of the Company should take in connection with the Arrangement or any aspect thereof and is not a recommendation to any person on how such person should vote with respect to the Arrangement or related transactions and proposals. Our opinion relates solely to the fairness, from a financial point of view, to the Company of the Exchange Ratio. We express no opinion herein as to the relative merits of the Arrangement and any other transactions or business strategies discussed by the Board of Directors of the Company as alternatives to the Arrangement or the decision of the Board of Directors of the Company to proceed with the Arrangement, nor do we express any opinion on the structure, terms or effect of any other aspect of the Arrangement or the other

transactions contemplated by the Arrangement Agreement or Plan of Arrangement. We are not experts in, and this opinion does not address, any of the legal, tax or accounting aspects of the proposed transaction, including, without limitation, whether or not the transactions contemplated by the Arrangement Agreement and Plan of Arrangement constitute a change of control under any contract or agreement to which the Company, ECU or any of their respective subsidiaries is a party. We have relied solely on the Company's legal, tax and accounting advisors for such matters. We have assumed that the Arrangement will have the tax consequences described in discussions with, and materials furnished to us by, representatives of the Company. We have also assumed that the representations and warranties made by the Company and ECU in the Arrangement Agreement are and will be true and correct in all respects material to our analysis.

We will receive a fee for rendering this opinion, which fee will not be contingent on the completion of the Arrangement. In addition, BMOCM has acted as financial advisor to the Company with respect to the Arrangement and will receive a fee for such services, a substantial portion of which fee payable to BMOCM is contingent upon the successful completion of the Arrangement.

In addition, the Company has agreed to indemnify us against certain liabilities arising out of our engagement. BMOCM, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. BMOCM has consulted with the Company from time to time on various matters, although none of such prior consultations involved a formal engagement of BMOCM by the Company. In addition, certain of BMOCM's affiliates are providing, and may have in the past provided, corporate banking services to the Company or its affiliates from time to time, and BMOCM or its affiliates may provide investment and corporate banking services to the Company, ECU and their respective affiliates in the future for which BMOCM or they may have received or will receive customary fees. BMOCM provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including derivative securities, of the Company or its affiliates for its own account and for the accounts of customers.

Our opinion has been approved by a fairness opinion committee of BMOCM. Our opinion has been prepared at the request and for the benefit and use of the Board of Directors of the Company in evaluating the fairness, from a financial point of view, to the Company of the Exchange Ratio. Our opinion may not be disclosed, in whole or in part, or summarized, excerpted from or otherwise referred to without our prior written consent, except that the opinion may be included in its entirety in a proxy statement made available by the Company to holders of its outstanding shares of common stock with respect to the Arrangement.

Based upon and subject to the foregoing, it is our opinion, as investment bankers, that as of the date hereof, the Exchange Ratio is fair, from a financial point of view, to the Company.

Very truly yours,

BMO Capital Markets
