Certain disclosure related to resource and reserve estimates in this Annual Report on Form 20-F has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of the United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. These definitions differ from the definitions in the United States Securities and Exchange Commission (“SEC”) Industry Guide 7 under the United States Securities Act of 1933, as amended (the “Securities Act”). Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms “mineral resource”, “measured resource”, “indicated resource” and “inferred resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part of 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 and legal 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 or legally mineable. 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 Industry Guide 7 standards as in place tonnage and grade without reference to unit measures.

Accordingly, information contained in this Annual Report on Form 20-F and the documents incorporated by reference herein contain descriptions of our mineral deposits that may not be comparable to similar information made public by US companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

In this annual report on Form 20-F, the following terms and acronyms have the following meanings:

This Annual Report on Form 20-F and exhibits attached hereto contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 and Canadian securities laws. Such forward-looking statements concern the Company’s plans for its properties, operations and other matters. These statements relate to analyses and other information that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management. Statements concerning estimates of mineral resources and reserves may also be deemed to constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered if the property is developed, and in the case of mineral reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “expects” or “does not expect”, “is expected”, “anticipates” or “does not anticipate”, “plans”, “estimates” or “intends”, or stating that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved) are not statements of historical fact and may be “forward-looking statements”. Forward-looking statements are subject to a variety of risks and uncertainties, which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation:

This list is not exhaustive of the factors that may affect our forward-looking statements. Some of the important risks and uncertainties that could affect forward-looking statements are described in this Annual Report on Form 20-F under “Description of the Business –Risk Factors”. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Forward-looking statements are made based on management’s beliefs, estimates and opinions on the date the statements are made. Investors are cautioned against attributing undue certainty to forward-looking statements.

In this document, references to “we”, “our”, “us”, the “Company” or “Pacific Rim” mean Pacific Rim Mining Corp. and its US subsidiaries (Pac Rim Cayman LLC (“PacRim”), Pacific Rim Exploration Inc. (“PREx”), and Dayton Mining (U.S.) Inc.); and Salvadoran subsidiaries (Pacific Rim El Salvador, S.A. de C.V. (“PRES”) and Dorado Exploraciones, S.A. de C.V. (“DOREX”)), inclusive, unless the context of the sentence clearly suggests otherwise.

The selected consolidated financial information set forth below for the years ended April 30, 2013, 2012, and 2011has been derived from the Company's audited consolidated financial statements as at and for the financial years ended April 30, 2013, 2012 and 2011, which were prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board (“IASB”), which differ in certain respects from the principles the Company would have followed had its consolidated financial statements been prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP”). The financial data presented below is qualified in its entirety by, and should be read in conjunction with, the audited consolidated financial statements and notes thereto as well as management’s discussion and analysis of results of operations, and the discussion in Item 5 of this Form 20-F. The Company’s reporting currency is the United States Dollar (“U.S. Dollar”, “USD” or “$”) and monetary data not otherwise labeled in this annual report on Form 20-F is stated in US Dollars. Historical results from any prior period are not necessarily indicative of results to be expected for any future period.

The following table outlines the common shares outstanding at and subsequent to the year end:

Unless otherwise indicated, all dollar amounts in this annual report on Form 20-F are in United States dollars. The exchange rate of Canadian dollars into United States dollars, on July 15, 2013, based on the noon rate of exchange as quoted by the Bank of Canada was CDN $1 = US $0.9603 or US $1.00 = CDN $1.0413.

An investment in the common shares of the Company involves a high degree of risk and must be considered highly speculative due to the nature of the Company’s business and the present stage of exploration and development of its mineral resource properties.

Failure to successfully address the risks and uncertainties described below could have a material adverse effect on the Company’s business, financial condition and/or results of operations, and the trading price of the Company’s shares may decline and investors may lose all or part of their investment.

The principal activity of the Company is mineral exploration, which is inherently risky. Exploration is also capital intensive, and the Company currently has no source of income. The risk factors that could affect the Company’s future results include, but are not limited to, those items discussed below. Descriptions of the Company’s exploration properties, including details of an ongoing legal action pertaining to the El Dorado property, are described in Item 4D – “Property, Plant and Equipment”.

We will need significant additional capital, which we may be unable to obtain.

The Company has no source of revenue and is reliant on its cash and short term investments in order to finance its exploration activities, general and administrative and legal expenses. The Company currently has negative working capital and its ability to continue operations and exploration activities as a going concern is dependent upon its ability to obtain financing. The Company will need to raise additional funds during fiscal 2014 to support exploration and administration expenses as well as various costs under PacRim’s Arbitration action (see Item 4B – “Business Overview”). Furthermore the Company does not have the funds in place to conduct any significant exploration programs, or mine development activities at the El Dorado property should the Company receive the permits allowing it to undertake these activities.

While the Company has been successful in obtaining its required funding in the past, there is no assurance that sufficient funds will be available to the Company in the future, or be available on favourable terms. Factors that could affect the availability of financing include fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application. Additional financing will require, but may not be limited to, the issuance of additional equity, which may be very dilutive to the Company’s shares and shareholders.

Failure to obtain additional financing could result in the Company’s failure to remain a going concern, the Company’s inability to continue the Arbitration action, or could cause the delay or indefinite postponement of further exploration and development of its projects with a possible loss of some properties.

There is substantial doubt as to our ability to continue as a going concern.

The Company’s financial statements have been prepared on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its commitments, continue operations, realize its assets and discharge its liabilities in the normal course of business for the foreseeable future. There are events and conditions that cast substantial doubt on the validity of that assumption. The Company will require additional financing for administrative purposes, for legal expenses related to the Arbitration and to continue to conduct ongoing exploration programs and meet future property commitments. The costs for the Arbitration are substantial and are anticipated to increase as the case proceeds to through the final, merits-based phase. Factors that could affect the availability of financing include fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application. Global securities markets and commodity prices are volatile and have fluctuated markedly in recent years. Most recently, commodity prices, in particular the price of gold, have decreased substantially. Volatility, and in particular decreases, in global stock markets and commodity prices may impact access to capital and/or the terms and conditions under which financing may be available. The Company believes it will be able to obtain the necessary financing to meet its requirements on an ongoing basis; however, there can be no assurance that the necessary financing will be obtained, and such financing, if available, may be very dilutive to the Company’s shares and shareholders. As it has in the past, the Company plans to obtain additional financing through, but not limited to, the issuance of additional equity.

The consolidated financial statements do not reflect adjustments in the carrying values of the assets and liabilities, the reported revenues and expenses, and the balance sheet classifications used, that would be necessary if the company were unable to realize its assets and settle its liabilities.

Because we have a history of losses and anticipate continued losses unless and until we are able to generate sufficient revenues to support our operations, we may lack the financial stability required to continue operations.

The Company has a history of losses and may continue to incur losses for the foreseeable future. As of April 30, 2013, the Company had an accumulated deficit of $94.5 million. The Company currently has no source of revenue and there can be no assurance that the Company will realize revenue growth or achieve profitability in the future.

The Company’s shares currently trade on the TSX in Canada and on the OTCQX platform in the US. The Company remains SEC-registered in the US. The Company’s ability to maintain its TSX listing will be dependent on meeting the exchange’s ongoing listing maintenance standards including provisions for minimum exploration work expenditures. The TSX may elect at any time to undertake a formal listing review of the Company, which could result in the Company’s shares being subject to delisting from the TSX, in which event the Company would seek a listing on the TSX Venture Exchange. However, there is no assurance that the Company would be successful in obtaining such a listing.

Our properties are in the exploration stage and are highly speculative in nature, which means there can be no assurance that our programs will result in the discovery of any economically feasible mineral deposits.

Resource exploration, development, and operation is a highly speculative business that involves significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate. While the discovery of precious metals and other minerals may result in substantial rewards, few properties that are explored are ultimately developed into producing mines. Major expenses may be required to locate and establish economically viable mineral deposits, to develop metallurgical processes and to construct mining and processing facilities at a particular site. It is impossible to ensure that the exploration or development programs planned by the Company will result in a profitable commercial mining operation. The potential for any project to eventually become an economically viable operation depends on numerous factors including: the quantity and quality of the minerals discovered if any, the proximity to infrastructure, metal and mineral prices (which vary considerably over time) and government regulations. The exact effect these factors can have on any given exploration property cannot accurately be predicted but the effect can be materially adverse.

Except for the El Dorado Project, on which a pre-feasibility study was completed in 2005, none of the Company's properties have a known body of ore and the Company’s proposed exploration programs are an exploratory search for ore.

Although mineral resource estimates included in this document (and/or in previous regulatory documents filed by the Company) have been carefully calculated, prepared, reviewed and/or verified by independent mining experts who are Qualified Persons, and have been reviewed by the Company, these amounts are estimates only and no assurance can be given that any particular level of recovery of gold and/or silver from mineral resources or previously disclosed reserves will in fact be realized or that an identified mineral resource will ever qualify as a commercially mineable (or viable) ore body which can be legally and economically exploited. Estimates of mineral resources and reserves, production and capital costs can also be affected by such factors as environmental permitting regulations and requirements, weather, environmental factors, unforeseen technical difficulties, unusual or unexpected geological formations and work interruptions. In addition, the grade of ore ultimately mined may differ from that indicated by drilling results. There can be no assurance that the percentage of gold recovered in small scale laboratory tests will be duplicated in large scale tests under on-site conditions or in production scale ore recovery.

The Company’s exploration properties are located in El Salvador. The Company may commence exploration programs in other jurisdictions in the future. As with most jurisdictions, El Salvador imposes certain requirements and obligations on the owners of exploratory properties including application requirements, periodic reporting requirements, limited terms and certain fees and royalty payments. The Company may acquire interests in properties in other North, Central and South American countries that may place substantial restrictions on the Company’s exploratory and development activities. There can be no assurance that additional significant restrictions will not be placed on the Company's existing or future properties or its operations. Such restrictions may have a materially adverse effect on the Company's business and results of operation.

Mining operations generally involve a high degree of risk. The Company’s operations are subject to all of the physical hazards and risks normally encountered in the exploration, development and production of precious metals and other minerals including unusual or unexpected geological formations, seismic activity, rock bursts, cave-ins, flooding and other conditions involved in the drilling and removal of material, any of which could result in damage to or destruction of documents, samples or drill core, damage to life or property, environmental damage and possible legal liability. It may not be possible to insure against these risks, or for economic reasons the Company may elect not to insure against these risks. The payment of liabilities as a result of the occurrence of any of these hazards may have a material adverse effect on the Company’s financial position.

There can be no assurance that the Company’s exploration and acquisition programs will yield new reserves to expand current resources. The development of the Company’s properties will require the commitment of substantial financial resources to conduct the time-consuming exploration and development of properties. There can be no assurance that the Company will generate any revenues or achieve profitability.

PRES, a subsidiary of PacRim, has applied for an exploitation concession over a portion of its El Dorado Project exploration licence area and has carried out the studies required by the authorities for this concession, including an EIS. The approval of the El Dorado EIS by the Salvadoran Ministry of Natural Resources and the Environment is a requirement for approval of the exploitation concession by the Ministry of Economy. The Company cannot say with certainty if or when the authorities in El Salvador will approve the El Dorado EIS or grant PRES an exploitation concession. The exploitation concession application area covers ground protected by an exploration licence granted to PRES that nominally expired in January 2005. Legal opinions secured by the Company indicate that El Salvadoran administrative laws and procedures assure PRES exclusive rights to the proposed exploitation concession area while the application is in process, despite the underlying exploration licence having expired. There can be no assurance however that this opinion will not be challenged by regulatory authorities or other third parties and that PRES’s legal rights to explore within the exploitation concession application area will be upheld indefinitely pending the outcome of the application process.

The Company conducted significant due diligence on the Remance Project in Panama prior to signing a letter of intent to acquire the project from Minera Clifton, including securing legal opinions on the title and tenure of the Remance exploitation concession. The Company is of the opinion that that title to the Remance project lies with Minera Clifton. However, the Remance property, as well as the Company's other exploration properties, may be subject to prior unregistered agreements or transfers or local land claims and title may be affected by undetected defects.

The expiry date of the initial term of the Remance exploitation concession has passed. Minera Clifton’s application for an extension of the Remance exploitation concession (as is provided for under Panamanian law) was recently denied by the Panamanian ministry responsible for mining, a decision which Minera Clifton is now appealing. The Company’s decision to sign a Final Agreement on the acquisition of this project is dependent on Minera Clifton winning its appeal and receiving an extension to the term of the Remance mining concession. There can be no assurance at this time that the ministry’s decision will be overturned and that the Remance exploitation concession extension will ultimately be granted. Although the Company intends to keep the Remance LOI in place (as there is no cost in doing so), the Company’s acquisition of the Remance project cannot be guaranteed.

The Company has investigated and believes it has good title to its properties. However, there is no guarantee that adverse claims to title will not arise in the future, nor can the Company express an opinion on how difficult the resolution of such claims would be under the laws of foreign jurisdictions.

Calculations of mineral reserves and of mineralized material are estimates only, subject to uncertainty due to factors including metal prices, inherent variability of the ore, and recoverability of metal in the mining process.

Although the Company has assessed the mineral resource estimates presented herein and mineral resource and reserve estimates documented in other regulatory filings, and believes that the methods used to estimate such mineral reserves and mineral resources are appropriate, such figures are estimates. As well, estimates of mineral reserves and mineral resources are inherently imprecise and depend to some extent on statistical inferences drawn from limited drilling, which may prove unreliable. Furthermore, no assurances can be given that the indicated level of recovery of gold or other minerals will be realized. Market price fluctuations of gold or other minerals may render reserves and deposits containing relatively lower grades of mineralization uneconomic. Moreover, short-term operating factors relating to the mineral reserves, such as the need for orderly development of the deposits or the processing of new or different grades, may cause mining operations to be unprofitable in any particular period.

Definitional standards for reporting mineralized material differ between United States reporting standards and the Canadian standards use in this Annual Report on Form 20-F.

We use the terms “measured resources,” “indicated resources” and “inferred resources” in this Annual Report on Form 20-F to comply with reporting standards in Canada. We advise US investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. While we have converted a portion of these resources to proven and probable reserves, US investors are cautioned not to assume that any part or all of the additional mineral deposits in these categories will ever be converted into mineral reserves. Mineral resources have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of measured mineral resources, indicated mineral resources, or inferred mineral resource will ever be upgraded to a higher category. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of a feasibility study or other economic evaluations. Investors are cautioned not to assume that any part of the reported measured mineral resource, indicated mineral resource, or inferred mineral resource in this Annual Report is economically or legally mineable. See “Cautionary Note to US Investors Regarding Resource and Reserve Estimates” above.

Our operations are subject to the inherent risks associated with mineral exploration activities in a foreign jurisdiction.

The Company's current exploration projects are located in El Salvador, and the Company may acquire exploration properties in other North, Central and South American countries. Mineral exploration and mining activities in foreign countries are subject to risks normally associated with the conduct of business in foreign countries and in addition its business activities may be affected in varying degrees by political stability and government regulations as these evolve in sovereign nations. These risks may include foreign labour disputes, invalidation of governmental orders, uncertain political and economic environments, war or civil disturbances, changes in laws, changes in foreign exchange rates, regulations and policies of governments, changes in foreign tax laws, delays in obtaining necessary permits, limitations on the repatriation of earnings and original investments and increased costs of and difficulty in obtaining financing. Currency fluctuations, exchange controls, change to tax regimes and political action could impair the value of the Company's assets in the foreign jurisdictions in which the Company operates.

Mining operations have inherent risks and liabilities associated with possible pollution of the environment and with the disposal of waste products occurring as a result of mineral exploration or the production of metals from producing mines. Laws and regulations involving the protection and remediation of the environment and governmental policies and regulations for the implementation of such laws and regulations are constantly changing and are, in general, becoming more restrictive and more costly to abide by. There may be costs and delays associated with compliance with these laws or regulations that could prohibit the Company from the development or expansion of a mine. Mine closure and reclamation cost requirements could change from current estimates.

PRES has experienced significant delays in the processing of its El Dorado EIS and exploitation concession application, and as a result PacRim initiated an Arbitration action against the GOES at ICSID headquarters in Washington, DC. There can be no assurance that PRES will be successful in either obtaining its sought-after El Dorado exploitation concession, or that any legal challenges PacRim has undertaken or that the Company or its subsidiaries may choose to undertake in the future to resolve this issue will be successful.

We are subject to additional risks due to our operations being in foreign countries.

The Company and its subsidiaries operate in certain parts of the world that have experienced social unrest, political and economic instability and resulting governmental corruption and may operate its business in manners that are contrary to the regulations imposed in the United States and Canada. While the Company has policies in place to ensure adequate monitoring of its activities and compliance with Canadian, United States and local laws and regulations in the countries in which it operates, there can be no assurance that the Company’s internal control policies and procedures will always protect it from reckless or negligent acts committed by its employees or agents. Such employees or agents may undertake actions that would result in a violation of law, including but not limited to, tax laws, customs laws, environmental laws, labour laws, permitting laws and regulations, industry laws or international anti-corruption and anti-bribery laws, including Canadian anti-corruption laws and the U.S. Foreign Corrupt Practices Act. Violations of these laws, or allegations of such violations, could disrupt the Company’s business and result in a material adverse effect on its business and operations.

The loss of key management personnel may adversely affect our business and results of operations.

The success of the operations and activities of the Company is dependent to a significant extent on the efforts and abilities of a small number of skilled and experienced executives and personnel. Due to the small size of the Company, the loss of any of these key persons or the inability of the Company to attract and retain additional highly-skilled employees may adversely affect its business and future operations. The Company does not maintain key employee insurance on any of its employees.

Certain of our directors or officers may be in a conflict of interest position.

The Company's directors and officers may serve as directors or officers of other resource companies or have significant shareholdings in other resource companies and, to the extent that such other companies may participate in ventures in which the Company may participate, the directors of the Company may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In the event that such a conflict of interest arises at a meeting of the Company's directors, directors who have such a conflict will declare their potential conflict and abstain from voting for or against the approval of such participation or such terms.

From time to time several companies may participate in the acquisition, exploration and development of natural resource properties thereby allowing for their participation in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in respect of any one program. It may also occur that a particular company will assign all or a portion of its interest in a particular program to another of these companies due to the financial position of the company making the assignment. In accordance with the laws of British Columbia, the directors of the Company are required to act honestly, in good faith and in the best interests of the Company. In determining whether or not the Company will participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider the degree of risk to which the Company may be exposed and its financial position at that time.

Significant and increasing competition exists for the limited number of gold acquisition opportunities available worldwide. As a result of this competition, some of which is with large established mining companies having substantial capabilities and substantially greater financial and technical resources than the Company, the Company may be unable to acquire future potential gold mining properties on terms it considers acceptable. The Company also competes with other mining companies in the recruitment and retention of qualified employees.

Costs at projects that the Company currently or in the future may explore or develop could be subject to variation from one year to the next due to a number of factors, such as changing ore grade, metallurgy and revisions to mine plans, if any, in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities such as fuel, rubber and electricity. Such commodities are at times subject to volatile price movements, including increases that could make production at certain operations less profitable. A material increase in costs at any significant location could have a significant effect on the Company’s financial condition and profitability.

We are subject to currency fluctuations that may affect our costs of doing business.

The Company's offices and primary activities are currently located in Canada, the United States, and El Salvador. Gold and silver are sold in international markets at prices denominated in US dollars. However, some of the costs associated with the Company's activities in Canada may be denominated in currencies other than the US dollar. Any appreciation of these currencies vis a vis the US dollar could increase the Company's cost of doing business in these countries. In addition, the US dollar is subject to fluctuation in value vis a vis the Canadian dollar. The Company does not utilize hedging programs to mitigate the effect of currency movements.

Mineral exploration involves a high degree of risk for which we may not be adequately insured.

The Company has purchased liability insurance that it believes is appropriate for the level of risk incurred, however there are no guarantees that the level of coverage of existing policies can or will be maintained. Furthermore, the Company does not carry insurance for political risk, nor environmental damage or pollution because such coverage cannot be purchased at reasonable costs. This lack of insurance coverage could result in material economic harm to the Company if a significant claim against the Company should occur.

We are subject to uncertain costs related to reclamation at Denton Rawhide.

During fiscal 2009 the Company sold the assets it held through its 49% interest in the Denton-Rawhide joint venture to its 51% partner Kennecott. At the time of this sale, future reclamation costs were estimated to be $5.3 million. Subsequently, in late calendar 2010, Kennecott sold its 100% interest in the Denton-Rawhide Joint Venture to a third party. According to the terms of Kennecott's 2010 sale, reclamation obligations at the Denton-Rawhide operation were separated such that Kennecott remains responsible for reclamation expenditures due to any disturbances created prior to the sale, and the purchaser becomes responsible for undertaking reclamation related to any disturbances created after the sale. As part of the sale of its interest in Denton-Rawhide to Kennecott, the Company had provided a guarantee on 49% of any reclamation and closure costs in the event that these expenditures (limited to those related to disturbances made up to the point the Company sold its interest in the operation) were to exceed $7.0 million. In other words, the Company's obligations are limited to pre-sale property conditions.

We are subject to environmental regulations pursuant to a variety of federal, state, provincial and local laws and regulations.

The Company’s exploration activities are subject to environmental regulation in the various jurisdictions in which it operates. 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. Environmental legislation is evolving in a manner that 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. There is no assurance that future changes in environmental regulation, if any, will not adversely affect the Company’s operations. Environmental hazards may also exist on the Company’s properties that are currently unknown to the Company and that have been caused by previous or existing owners or operators of the properties.

Environmental approvals and permits are currently, and may in the future, be required in connection with the operations of the Company. To the extent that such approvals are required and not obtained, the Company may be curtailed or prohibited from continuing in its exploration, development or mining activities or from proceeding with its exploration or development plans for current properties.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions that cause exploration, development or mining activities to cease or be curtailed and may include corrective measures requiring capital expenditures or remedial actions. In such an event, the Company could be required to compensate those suffering loss or damage by reason of the Company’s activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations.

Amendments to existing environmental laws and regulations governing exploration, development and mining activities of mining companies, or more stringent application of current laws and regulations could have a material adverse impact on the Company causing increases in exploration expenses, capital expenditures or production costs, or a reduction in production levels at producing operations, or require abandonment or delays in development of new mining properties.

We are subject to ongoing and increasing compliance obligations as a result of being a public company, which we may not be able to satisfy.

Legal, accounting and other expenses associated with public company reporting requirements have increased significantly in the past decade. The Company anticipates that general and administrative costs associated with regulatory compliance will continue to increase alongside corporate governance requirements, including rules and requirements of the SEC, Canadian Securities Administrators, the TSX and the OTCQX. The Company expects these rules and regulations to continue to result in significant legal and financial compliance costs and to make some activities more time-consuming and costly. There can be no assurance that the Company will continue to effectively meet all of the requirements of the regulations to which it must comply, including various sections of the Sarbanes-Oxley Act of 2002 and Canadian National Instrument 52-109, Certification of Disclosure in Issuers’ Annual and Interim Filings (“NI 52-109”). Any failure to effectively implement new or improved internal controls, or to resolve difficulties encountered in their implementation, could harm the Company’s operating results, and could cause the Company to fail to meet reporting obligations or result in management being required to give a qualified assessment of the Company’s internal controls over financial reporting. Any such result could cause investors to lose confidence in the Company’s reported financial information, which could have a material adverse effect on the Company’s stock price. The Company also expects these rules and regulations may make it more difficult and more expensive for it to obtain director and officer liability insurance, and it may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for the Company to attract and retain qualified individuals to serve on its board of directors or as executive officers. If the Company fails to maintain the adequacy of its internal controls, the Company's ability to provide accurate financial statements and comply with the requirements of the Sarbanes-Oxley Act of 2002 and/or NI 52-109 could be impaired, which could cause the Company's stock price to decrease.

Future sales of common shares by existing shareholders could decrease the trading price of our common shares.

The sale of a large number of common shares of the Company in the public markets, or the potential for such sales, could decrease the trading price of the Company’s common shares and could negatively impact the Company’s ability to raise capital through future sales of common shares.

We cannot guarantee that we will remain a foreign private issuer, and if our status changes we will be subject to increased compliance costs.

The Company is required to determine its “Foreign Private Issuer” status (as defined in Rule 3b-4(c) under the U.S. Securities and Exchange Act of 1934 (as amended) (the “Exchange Act”) for the purposes of U.S. securities law), annually at the end of its second fiscal quarter. Less than 50% of the Company’s voting securities were held by U.S. residents as of the last business day of its most recently completed second fiscal quarter and as such, the Company is considered a Foreign Private Issuer. Though not strictly required to, the Company also meets the following secondary conditions that would assure its Foreign Private Issuer status: (i) a majority of its executive officers and directors, taken separately, are non-U.S. citizens or residents, (ii) more than 50% of its assets are located outside the U.S., and (iii) the business of the Company is principally administered outside the U.S. The Company may in the future lose its foreign private issuer status if it fails to meet any of the aforementioned criteria.

The regulatory and compliance costs to the Company under U.S. securities laws as a U.S. domestic issuer may be significantly more than the costs the Company incurs as a Canadian foreign private issuer eligible to use the multijurisdictional disclosure system. If the Company is not a foreign private issuer it would be required to file periodic and current reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. This could have a materially adverse impact on the Company’s corporate overhead costs and its ability to raise future financing.

We are a foreign corporation and most of our directors and officers are outside of the United States, which may make enforcement of civil liabilities difficult.

We are incorporated under the laws of the Province of British Columbia, Canada. The majority of its Directors are resident in Canada. Consequently, it may be difficult for US investors to affect service of process within the United States upon us or upon those Directors or officers who are not residents of the United States, or to realize in the United States upon judgments. Judgments of United States courts predicated upon civil liabilities may be enforceable in Canada by a Canadian court if the US court in which the judgment was obtained had jurisdiction, as determined by the Canadian court, in the matter. There is substantial doubt whether an original action could be brought successfully in Canada against any of such persons or the Company predicted solely upon such civil liabilities.

The unprecedented events in global financial markets in the past several years have had a profound impact on the global economy. Many industries, including gold mining industry, have been and continue to be impacted by these market conditions. Some of the key impacts of the current financial market turmoil include contraction in credit markets resulting in a widening of credit risk, devaluations, high volatility in global equity, commodity, foreign exchange and precious metal markets and a lack of market confidence and liquidity. A continued or worsened slowdown in the financial markets or other economic conditions, including but not limited to, sovereign debt and government solvency conditions, consumer spending, employment rates, business conditions, inflation, fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates and tax rates, may adversely affect our growth and profitability. Specifically:

These factors could have a material adverse effect on our financial condition and results of operations.

The legal and commercial name of the Company is “Pacific Rim Mining Corp.”. All references to “Pacific Rim” or “the Company” encompass the Canadian corporation, Pacific Rim Mining Corp, its U.S. subsidiaries and Salvadoran subsidiaries, inclusive.

Pacific Rim’s shares trade under the symbol PMU on the Toronto Stock Exchange (“TSX”) and on the OTCQX market in the US under the symbol PFRMF.

The Company is domiciled in British Columbia, Canada and was formed by the amalgamation of Dayton Mining Corporation (“Dayton”) and Pacific Rim Mining Corp. (“Pacific Rim”) on April 11, 2002 under the former Company Act (British Columbia).

Effective March 29, 2004, the British Columbia legislature enacted the Business Corporations Act (British Columbia) (the “New Act”) and repealed the former Company Act (British Columbia) which previously governed the Company. At the Company’s annual general meeting held on September 22, 2004, the Company’s shareholders approved various changes and alterations to the Company’s articles and authorized capital that brought the Company’s articles in line with provisions of the New Act. The changes were effected and the British Columbia Registrar of Companies issued a new Notice of Articles on January 20, 2005.

The Company’s principal place of business is located at Suite #1050, 625 Howe Street, Vancouver, British Columbia, V6C 2T6 and its registered and records office is located on the 10^thFloor, 595 Howe Street, Vancouver, British Columbia, V6C 2T5. The Company, through its subsidiaries, has administration offices in Nevada and El Salvador. The Company’s US agent is Dorsey & Whitney LLP, located at 1400 Wewatta Street, Suite 400, Denver, Colorado 80202-5549, USA.

Additional sources of information regarding Pacific Rim Mining Corp. include: information available on SEDAR (www.sedar.com) including the Company’s unaudited interim financial statements published quarterly; the Company’s 20-F filing (available at www.sec.gov); and, the Company’s corporate website www.pacrim-mining.com and Spanish-language informational website (www.pacificrim.com.sv).

The Company’s only capital expenditures over the past three fiscal years (the twelve months ended April 30, 2013, 2012 and 2011) are payments made to ICN Resources Ltd. of 200,000 common shares of the Company on July 14, 2011 and 200,000 common shares of the Company on July 6, 2012 in respect of the Hog Ranch Definitive Agreement (see Item 4D – “Mineral Properties – Other Properties”). The Company made no capital divestures during the past three fiscal years.

Pacific Rim is a mineral exploration company focused on high grade, environmentally clean gold deposits in the Americas and committed to excellence in environmental stewardship and social responsibility. Pacific Rim’s primary asset is the advanced-stage, vein-hosted El Dorado gold deposit in El Salvador (see Item 4D – “Mineral Properties – El Salvador Properties”), where the Company also owns several grassroots gold projects. The Company is continuously evaluating additional exploration opportunities elsewhere in the Americas.

The Company’s business activity in recent years has primarily been focused on resolving the El Dorado project permitting impasse, including legal recourse. In addition, the Company continues to seek new exploration opportunities that fit its areas of focus and expertise.

The El Dorado gold project in El Salvador was the focus of virtually all of the Company’s exploration work between 2002 and 2008, when efforts to advance its El Salvador projects, including El Dorado, ceased as a result of the Government of El Salvador’s (“GOES”) passive refusal to issue a decision on the Company’s application for environmental and mining permits for the El Dorado project. The El Dorado project is now the subject of an arbitration claim (the “Arbitration”) being heard at the International Center for the Settlement of Investment Disputes (“ICSID”) in Washington, DC. Initiated in 2009 by the Company’s subsidiary and owner of the El Dorado project, PacRim, the Arbitration claim was originally filed under the Dominican Republic-United States-Central America Free Trade Agreement (“CAFTA”) and the Investment Law of El Salvador (the “Investment Law”). In its decision related to jurisdiction objections filed by the GOES, ICSID, in June 2012, ruled that the Arbitration could proceed under the Investment Law to its final phase wherein the merits of the claim will finally be addressed. Notwithstanding the ongoing legal action, the Company continues to seek a negotiated resolution to the El Dorado permitting impasse and to resuming its advancement of the El Dorado project.

Significant technical and corporate events that occurred during the twelve months ended April 30, 2013 include:

Important corporate and technical issues facing the Company in the coming fiscal year (and beyond) include: the Company’s ability to secure financing for the continuation of PacRim’s Arbitration action; the Company’s ability to secure adequate financing for ongoing general working capital purposes and maintenance of the El Salvador properties; the Company’s ongoing efforts to persuade the GOES to reconsider its actions and inactions in relation to mining and its role in the economic development of El Salvador; developments related to the Arbitration claim; developments related to the potential signing of a formal option agreement to acquire the Remance project and the subsequent undertaking of an exploration and drilling program at Remance if, as, and when it is formally acquired; and, the continued search for additional exploration project opportunities. Additional financing will be necessary during fiscal 2014 in order for the Company to continue its business operations including the Arbitration. The Company has been successful in raising funds through equity financing in the past but there can be no assurance that such financing will be available in the future, or if so, available under favourable terms, or that alternatively, financing through means other than the issuance of equity can be achieved. Readers are strongly encouraged to review the Risk Factors in Item 3D – “Risk Factors”, above.

The business of mining and exploration involves a high degree of risk. The Company is entirely reliant on its current cash and cash equivalents and future financings and/or financial arrangements in order to fund legal, exploration and administration expenses. Additional funding will be required in the future to continue the Arbitration claim, to maintain its exploration properties, and for administrative purposes. The Company’s ability to secure future financing is dependent on numerous factors, many of which are outside of the Company’s control, including fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application. While these factors are dynamic and likely to change over time, at present, equity financing for mineral exploration companies is difficult. The Company believes it will be able to obtain the necessary financing to meet its requirements on an ongoing basis; however, there can be no assurance that the necessary financing will be obtained. Furthermore, given the Company’s recent share price and the current state of equity markets, such financing, if available, may be very dilutive to the Company’s shares and shareholders. As it has in the past, the Company would likely seek additional financing through, but not limited to, the issuance of additional equity. Readers are strongly encouraged to review the Risk Factors in Item 3D – “Risk Factors”, above.

The mineral property exploration and development business, in general, is intensively competitive and there is not any assurance that even if commercial quantities of ore are discovered, a ready market will exist for the sale of same. Numerous factors beyond our control may affect the marketability of any substances discovered. These factors include market fluctuations; the proximity and capacity of natural resource markets and processing equipment; and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of mineral and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may make it difficult for us to receive an adequate return on investment.

We compete with many companies possessing greater financial resources and technical facilities for the acquisition of mineral concessions, claims, leases and other mineral interests as well as for the recruitment and retention of qualified employees.

The Company’s financial results are not significantly impacted by seasonality. As it has no source of revenue, the Company typically incurs net losses as a result of its expenses, which vary as a function of exploration work undertaken, which has been minimal since July 2008, and the level of legal activity related to the Arbitration action that commenced in April 2009.

Pacific Rim’s exploration properties are located in El Salvador. Federal regulatory agencieshaving authority over the Company’s exploration activities in El Salvador include but are not limited to the Ministerio de Economia (Ministry of Economy, or “MINEC”), which has authority over the granting of exploration and mining permits, and the Ministerio de Medio Ambiente y Recursos Naturales (Environment and Natural Resources Ministry, or “MARN”), which grants environmental permits and regulates environmental protection within the country of El Salvador. See Risk Factors, above, and Item 4 D “Property, Plant and Equipment” – El Salvador Mining Regime for a discussion of government regulation of the Salvadoran mining industry.

Unless the context otherwise indicates, reference to the term the “Company” in this Annual Report on Form 20-F includes Pacific Rim Mining Corp. and its subsidiaries.

The Company is a mineral exploration corporation engaged, through its subsidiaries, in the acquisition, exploration and, if warranted, development of precious metals properties, primarily gold and silver.

The Company is principally involved in the exploration for high-grade epithermal gold and silver deposits in the Americas. The Company’s only advanced material project is the El Dorado gold property in El Salvador and the Company continues to search for exploration projects to acquire in the Americas that meet its exploration focus.

The following is based on the Company’s understanding of the El Salvador mining regime.

Under the laws of El Salvador, the government owns all mineral rights. All private and government-owned lands that have not been declared areas of protection for reasons of national sovereignty, areas of cultural or social interest, areas of ecological or environmental protection or areas of capitation of surface or underground waters for potable water supply; zones occupied by public service facilities; or areas that are within the urban limit of cities or towns are open to exploration and are available through application for an exploration license, which can subsequently be converted to an exploitation concession upon compliance with certain conditions. An exploration license is held by payment of an annual fee, compliance with the environmental laws of the country and fulfilment of the technical exploration program, which may be modified on an annual basis. El Salvadorian mining laws do not discriminate between nationals and foreigners.

El Salvador’s current mining law, which was enacted in 1996 and last amended in 2001, governs the provisions for granting of exploration licences and exploitation concessions. By granting an exploitation concession, the El Salvadoran Ministry of Economy’s Department of Hydrocarbons and Mines confers upon the applicant the right to produce and sell valuable commodities recovered from the natural resources within the area of the concession. To be granted an exploitation concession, which is a necessary step to commencing mining extraction activities, an environmental permit based on an Environmental Impact Study (“EIS”) must first be approved by MARN. The applicant must also satisfy a number of other conditions. Once granted, the concession requires that development activities commence within 12 months of the date of the final concession agreement and that the mine and associated facilities be built and operated in accordance with the conditions of the environmental permit.

The Company’s most advanced property in El Salvador is the El Dorado Property, which consists of three exploration licenses (contiguous to and completely surrounding the pending exploitation concession area), which the Company, indirectly through its wholly-owned subsidiaries, holds as to a 100% interest.

The information presented below under the headings “Property Description and Location”, “Accessibility, Climate, Local Resources, Infrastructure and Physiography”, “History”, “Geological Setting”, “Exploration”, “Mineralization”, “Sampling and Analysis”, “Security of Samples”, “Metallurgy”, and “January 2008 Resources Estimate” summarizes information prepared under the supervision of Mr. Steven Ristorcelli, P.Geo., of Mine Development Associates and is drawn from a report dated March 3, 2008 entitled Technical Report Update on the El Dorado Project Gold and Silver Resources (the “March 2008 Technical Report”) co-authored by Mr. Ristorcelli and Mr. Peter Ronning, P.Eng., each of whom are independent Qualified Persons as defined in NI 43-10. This information has been updated where necessary (for clarity and to reflect developments that have occurred since the date of publication of the March 2008 Technical Report) by or under the supervision of William Gehlen, Certified Professional Geologist, a Qualified Person for the purposes of NI 43-101. Mr. Gehlen is the Vice-President of Exploration of the Company. Information presented below for the El Dorado Property under all other headings was prepared by the Company.

Predecessor Dayton upon its acquisition of Mirage Resource Corp. in April 2000 acquired the El Dorado Property. Mirage initially acquired the El Dorado Property by option agreement dated June 23, 1993 from Zinc Metal Company (“ZMC”) of Toronto, and its wholly-owned subsidiary, New York and El Salvador Mining Company. The option was exercised on August 25, 1994 in accordance with its terms by payment of $175,000 to ZMC and by the parties having incurred aggregate expenditures in excess of $800,000. Pursuant to the terms of the option agreement, the El Dorado Property is subject to annual advance minimum royalty payments, which are the greater of $50,000 per year or a 3% net smelter return royalty in favour of ZMC. The Company has the right to purchase the royalty from ZMC for $4.0 million ($1.0 million for the first one-half and $3.0 million for the second one half) provided that at least one-half of the royalty is acquired within six months of the commencement of commercial production. In addition, the government of El Salvador is entitled to a 2% net smelter return royalty.

By agreement dated March 29, 2006, the Company superseded an option agreement dated November 14, 2003 to acquire a parcel of land suitable for mineral exploitation activities within the El Dorado exploration licence area. Under the terms of the new agreement, the Company has prepaid an annual rental fee in the amount of $29,000 with the option to purchase the parcel for a payment of $971,000 at any time up to April 1, 2007. During fiscal 2007 the Company commenced the process of exercising its option to purchase one of the larger parcels of land over which it holds a purchase option agreement (negotiated during fiscal 2004), and advanced to the property owner $0.3 million of the $1.0 million total negotiated option payment. During fiscal 2008, upon transfer of title in the parcel of land to the Company, the final $0.7 million was paid. Although the El Dorado Property contains geological mineral resources, none of the Company’s properties in El Salvador, including the El Dorado Property, contain known ore reserves (as defined under the SEC’s Industry Guide 7) and all work programs are exploratory searches for ore grade mineralization.

The El Dorado Property is in the Department of Cabañas, El Salvador, approximately 74 kilometres northeast of San Salvador, the capital city of the nation, and 10 kilometres southwest of the town of Sensuntepeque.

The El Dorado Property (see Figures 1 and 2 below) is comprised of three exploration licenses totalling 14,407 hectares (approximately 144 square kilometres) with nominal expiry dates of September 28, 2013 (one license) and September 29, 2013 (two licenses), and a 1,275 hectare (12.75 square kilometre) area pending conversion to an exploitation concession (“Exploitation Concession”), which underlying exploration license has a nominal expiry date of January 1, 2005. In accordance with Salvadoran Law, PRES presented a request for the conversion of this 12.75 square kilometre portion of the El Dorado exploration licences to an exploitation concession in December 2004. The conversion process is currently pending ministerial acceptance of PRES’s Environmental Impact Study and issuance of the environmental permits. As a result of restricted access to documents in El Salvador during the on-going Arbitration action, the Company has not had the ability to confirm or renew its existing Salvadoran exploration licences during fiscal 2013. Legal opinions secured by the Company indicate that El Salvadoran administrative laws and procedures assure the Company’s exclusive rights to the proposed exploitation concession area while the application is in process, despite the underlying exploration licence having expired. There can be no assurance however that this opinion will not be challenged by regulatory authorities or other third parties and that PRES’s legal rights to explore within the exploitation concession application area will be upheld indefinitely pending the outcome of the application process. The Company continues to hold the 1,275 hectare pending Exploitation Concession area beyond its expiry date as it has declared its intention to convert the land holding to an Exploitation Concession, which will have a term of 30 years and may be extended if warranted. See “El Salvador Mining Regime” above. The cost to hold the licenses is a rental of $300 per square kilometre, amounting to $47,046 per year. The Company is up to date with the regulatory obligations required to maintain the licenses in good standing and is awaiting final approval of the pending Exploitation Concession.

El Dorado is subject to a royalty of 3% of net smelter returns in favour of a previous property owner. Pacific Rim has the right to buy back the royalty for $1 million for the first 1.5% and $3 million for the second 1.5%, provided that at least one half of the royalty is acquired within six months of the commencement of commercial production.

In addition to its mineral rights, the Company owns approximately 765,000 square metres of real estate in the central part of the El Dorado Property.

Part of the El Dorado license area was the scene of mining by another company between 1948 and 1953. The Company and its environmental consultants believe that there are no existing environmental liabilities on the project related to that earlier period of production nor to the exploration activities of the Company and its predecessor companies.

The exploration license area contains several prospects and deposits. Their stage of exploration and development ranges from recently discovered veins that have never been drilled to deposits that have resource estimates. The Company’s permanent installations on the property at the present time consist of a laboratory for crushing rock samples and core storage warehouses with facilities for describing and sampling drill core. None of the mid-20^thcentury mine workings are accessible at present.

The El Dorado Property is accessible by a paved road that crosses the El Dorado Property. The travel time from the project site to San Salvador is approximately two and one-half hours, depending on traffic levels.

The area has a large rural population and Sensuntepeque is a moderate sized town of approximately 20,000 people. Unskilled labour and persons with general business and technical skills should be readily available. El Salvador does not have an indigenous mining industry, so personnel with exploration and mining skills need to be trained or come from elsewhere.

The usual public utilities are available in Sensuntepeque. The communication infrastructure, including telephone and internet, is serviceable. The existing buildings on the project site are connected to the national electrical grid, but the power supply is not considered reliable enough to service a mine.

The terrain in the El Dorado Property area is one of moderate relief surrounded by higher hills to the north, east, and west. Elevations range between 200 m and 800 m above sea level. A tropical climate prevails, with a pronounced wet season from May to October and a dry season the remainder of the year. The project area contains shallow topsoils and volcanic subsoils that are cultivated for seasonal crops. Five perennial streams or rivers traverse the El Dorado License area. Water levels vary with the seasons with good flows being maintained during the wet season.

The colonial Spanish discovered gold in the district in the early 1500’s, and there was sporadic, largely unrecorded small-scale production until the late 1800’s. In the period from 1948 to 1953, the New York and El Salvador Mining Company operated an underground mine, producing approximately 270,000 tonnes of ore yielding about 72,500 troy ounces (2,250 kilograms) of gold.

Extensive exploration since 1993 has included surface geological mapping, rock sampling and prospecting, campaigns of hand and bulldozer trenching, core drilling, and minor reverse circulation drilling.

El Salvador can be divided into four morphological-geological units: Coastal Plains, Coastal Ranges, Great Interior Valley, and the Northern Mountain Ranges. El Dorado is situated in the Great Interior Valley, underlain by Eocene felsic to mafic volcanic rocks; in other words, dark to light coloured volcanic rocks in the order of 38 to 55 million years old.

Mineralization on the El Dorado Property consists of gold and silver bearing quartz veins that are contained within the volcanic rocks. The gold and silver bearing veins of the El Dorado district, of which at least 36 exceed 1 m in width, occur over an area exceeding 50 square kilometres. Vein mineralization is dominated by quartz and calcite and ranges in width between 1 m and 15 m in surface exposures. The vein systems are up to 3 km in length, dip steeply, and generally form ridges.

The mineralization fits the model of the low sulphidation epithermal type of mineralization, also referred to as the adularia-sericite type. A number of deposits around the world that belong to this type are being profitably mined.

In terms of its structure and mineral deposits the Exploration License Area can be divided into 3 districts, Central, Northern, and Southern. The three districts are separated from each other by northwest trending regional scale faults whose primary displacement was lateral. Within each district, deposits are contained within quartz veins that formed along fractures that opened under tension. The mineralized veins are for the most part within about 30 degrees of vertical and trend generally north-south, but there is considerable variation both within and between districts.

The long history of recent exploration on the El Dorado Property includes extensive mapping of mineralized structures, lithogeochemical sampling, trenching and drilling. There have been numerous ancillary studies including environmental base line work.

Geological mapping to varying levels of detail, done by the Company and its predecessors, covers approximately 2,000 hectares of the 14,400 hectare property. Digital maps have been generated at scales ranging from 1:1,000 to 1:10,000. In addition, the project archives contain numerous individual maps of trenches, veins and target areas at various scales.

Geological mapping has been accompanied by frequent sampling of the rocks on the surface. The samples are variously described as channel samples, chip channel samples, selected chips, random chips and grab samples.

The El Dorado License area contains many deposits, prospects and occurrences in veins, hot spring deposits and hydrothermal breccias. They are found in three districts, north, central and south, that are distinguished from each other by the dominant vein orientations and the level of the hydrothermal system that is exposed on the present-day surface. The veins have complex, multi-stage histories of formation.

The dimensions of mineralized veins are as varied as their exploration status, ranging from those known only in single outcrops to those that have been traced on the surface over lengths of between one and two kilometres. Systems of related veins are up to three kilometres long. In those veins that have been mined or extensively drilled, mineralization has been demonstrated to exist over vertical intervals of up to 300 metres. (In considering vein lengths and vertical dimensions it is important to note that at a detailed level mineralization in this type of system is highly variable).

The sampling method used by the Company field personnel varies with the purpose of the sample. Geologists doing initial reconnaissance or prospecting may collect selected grab samples from new discoveries. Such samples would be intended only to determine if minerals of interest are present, not to estimate grades for any volume of material.

For more systematic sampling, outcrops are cleaned off and in some cases shallow hand trenches are dug. Continuous chip samples are collected over intervals selected by a geologist. In many cases local labourers do the sampling, under a geologist’s supervision. The manner of sampling is recorded in field notes and is entered into the digital database of surface samples.

Intervals from drill core to be sampled are selected by the geologist logging the core. All vein material and visibly mineralized material is sampled, with enough immediately adjacent, apparently unmineralized material sampled to make sure that all intervals are adequately tested. Sampling is done after logging is complete. The core is sawn in half along its axis. The Company’s immediate predecessor as operator, Dayton, also used a rock saw for sampling core from 13 holes it drilled in 2000. Operators prior to Dayton used a percussion core splitter.

Core recovery, which affects the degree to which samples are representative, is very good in the current drilling. In mineralized intervals it averages better than 98%. In past drilling, prior to the Company becoming operator, resource estimators found local problems with core recovery, finding that it averaged as low as 76% in some mineralized veins.

The Company collected a large quantity of unmineralized material from a site in the region. This material is used as sample “blanks” that are inserted into the sample stream at a rate of one into every batch of 25 samples, as a quality control measure.

All of the Company’s samples are analyzed at the laboratory of Inspectorate America in Sparks, Nevada. About 25% of the samples are analyzed in duplicate by selecting a batch of material already pulverized by Inspectorate and sending it to another lab, American Assay. Once the results of the re-analysis are received, about 15% to 20% of the duplicated samples are selected for re-analysis starting with the coarse reject material.

All samples which return gold results exceeding 3 g Au/tonne in the initial analysis are analyzed again using a fire assay preparation with a gravimetric finish.

All sampling is done by the Company’s employees, either geologists or labourers supervised by geologists. Once collected, samples are kept at the Company’s on-site facility until they are picked up by employees of Inspectorate America’s Guatemalan affiliate. They are transported by road to the Guatemalan laboratory, where they are prepared and trans-shipped to Nevada for analysis. Some of the samples may, from time to time, be opened and inspected by border officials at the border crossing from El Salvador to Guatemala.

Metallurgical test work has shown the El Dorado mineralization responds well to milling and cyanide leaching. Recoveries of over 92% for gold and over 88% for silver are expected. Historic recoveries during past production ranged from 87% to 91.5% for gold and 77.7% for silver.

On January 17, 2008 the Company released the results of an updated resource estimate for the El Dorado gold project, in which 1.4 million gold equivalent ounces were tabulated in the Measured and Indicated resource categories combined and a further 0.3 million gold equivalent ounces were tabulated in the Inferred category. Full details of the 2008 El Dorado resource estimate, by deposit and resource category, are presented below.

Notes:
1) Resources based on a gold equivalent cut-off grade of 4.0 g AuEq/t and greater than a grade-times-thickness of 4 (g AuEq/t x meters)
2) Gold equivalents based upon a silver to gold ratio of 70:1
3) Resources for the Minita, South Minita, Nance Dulce, Coyotera and Nueva Esperanza deposits are unchanged from the July 2006 El Dorado Resource Estimate (see NI 43-101 disclosure)

The mineral resource estimates presented above have been calculated in accordance with National Instrument 43-101 as required by Canadian securities regulatory authorities, which differs from standards of the SEC. The resource estimates contained in this discussion would not be permitted in reports of US Companies filed with the SEC. See “Cautionary Note to US Investors Regarding Resource and Reserve Estimates” above.

The resources were estimated by interpreting drill intercepts in cross section, coding samples, capping assays, compositing to vein thicknesses, and estimating grades and thicknesses of each of the veins into three dimensional grade thickness models. Each of the three veins comprising the Minita resource, ten veins comprising the South Minita resource, and five veins comprising the Balsamo resource were estimated separately. The 4.0 g/t cut-off grade (wherein gold equivalents are based on a silver to gold ratio of 70:1 and greater than a grade-times-thickness of 4 (g AuEq/t x metres)) is predicated on estimated operating costs of $49.68 per tonne, estimated gold recovery of 90% and a gold price of $400 per ounce. These parameters stem from the Company’s 2005 El Dorado prefeasibility study, the results of which are based on various input estimates related to costs and commodity prices that were current at the time of its publication. Readers are cautioned that significant changes have occurred in a number of the inputs used in the January 2005 El Dorado prefeasibility study since its publication in January 2005. However, the Company and its consultants elected to maintain the 4.0 g/t gold equivalent cut-off grade for the 2008 El Dorado resource estimate in order to facilitate comparisons between the current resource estimate and the 2006 resource estimate. Full technical reports related to the 2008 El Dorado resource estimate, the 2006 El Dorado resource estimate and the 2005 El Dorado pre-feasibility study are publicly available on SEDAR at www.sedar.com.

The foregoing disclosure under “January 2008 Updated Resource Estimate” is based on information prepared under the supervision of Mr. Steven Ristorcelli, P.Geo., of Mine Development Associates, contained in a report dated March 3, 2008 entitled Technical Report Update on the El Dorado Project Gold and Silver Resources” co-authored by Mr. Ristorcelli and Mr. Peter Ronning, P.Eng. each of whom are independent Qualified Persons. This information has further been reviewed and verified by Mr. William Gehlen, Certified Professional Geologist and a Qualified Person. Mr. Gehlen is the Vice-President of Exploration of the Company and supervised the Company’s exploration work on the El Salvador properties. The Company’s sampling procedures follow the Exploration Best Practices Guidelines outlined by the Mining Standards Task Force and adopted by the TSX. Samples have been assayed using fire assay with a gravimetric finish on a 30-gram split. Quality control measures, including check- and sample standard-assaying, are being implemented. Samples were assayed by Inspectorate America Corporation in Reno, Nevada, an ISO 9002 certified laboratory, independent of the Company.

In July 2008, the Company suspended all drilling activity at the El Dorado project. This decision was made in order to preserve capital and substantially reduce Pacific Rim’s El Salvador investment activity while the El Dorado permitting issue remains unresolved. See “Environmental Impact Study and Mining Permit” below. The Company did not conduct any significant exploration work to further advance the El Dorado project during fiscal 2013. Exploration activities undertaken by the Company at the El Dorado project during fiscal 2013 were restricted to care and maintenance responsibilities, baseline environmental data collection and community consultations.

A summary of El Salvador’s mining regime is presented in “El Salvador Mining Regime” above.

In September 2004, PRES submitted an EIS to MARN for a 750 tonne per day operation based on producing precious metals from the Minita deposit alone. In September 2005, the finalized EIS, which incorporated initial comments from MARN, was resubmitted to MARN. MARN then conveyed its technical approval of the EIS, and instructed PRES to submit the EIS for public comment, which was carried out in October 2005. In March 2006, PRES received from MARN a list of issues raised during the public comment period and was asked to amend the EIS to address these and a number of other issues. In October 2006, the amended EIS, which included the requested clarification on a number of items, was resubmitted to MARN. Finally, in December 2006, PRES submitted a proposal for a water treatment plant in response to additional comments by MARN.

Well over six years have passed since the El Dorado EIS was submitted in its final form to MARN, during which time MARN has failed to take action on approval of the EIS. This in turn is preventing a resolution to PRES’s exploitation concession application.

In April 2009, PacRim, a Nevada corporation and a wholly-owned subsidiary of Pacific Rim filed international arbitration proceedings against the GOES under CAFTA and the Investment Law of El Salvador in its own name and on behalf of PRES and DOREX (collectively the “Enterprises”). A Notice of Intent to commence international arbitration proceedings had previously been filed by PacRim in December 2008. PacRim has retained the Washington, DC-based international law firm Crowell & Moring LLP to represent it in the arbitration.

Since PacRim initiated the Arbitration claim in 2009, the GOES has filed two objections to the action (the “Preliminary Objections” and the “Jurisdiction Objections”) in an attempt to terminate the Arbitration. On both occasions the Tribunal disagreed and ruled that the action could proceed. Additional details are provided below.

Since acquiring the El Dorado project in El Salvador in 2002, PacRim and the Enterprises have operated in full compliance with Salvadoran law, including the country’s environmental, mining and foreign investment laws, and have met or exceeded all applicable standards while conducting business in El Salvador. Ample evidence, however, demonstrates that the GOES has failed to fulfill its obligations.

PacRim’s claims are based on the GOES’s breaches of international and Salvadoran law arising out of the GOES’s improper failure to finalize the permitting process in accordance with Salvadoran law. This conduct by the GOES has resulted in a significant loss to PacRim, the shareholders of Pacific Rim and to the local communities, and has unnecessarily delayed normal development of these valuable deposits.

Pacific Rim’s mandate to its shareholders is to build a gold mining company that explores and develops gold deposits in an environmentally responsible manner. The El Dorado Mine, as designed and submitted to the GOES six years ago, would set new precedents for environmental protection in all of the Americas and exceeds current Canadian and US environmental standards. Preservation of water quality and quantity is a key component of the industry-leading El Dorado mine design. The Company owns, or has negotiated rights to work on all surface lands needed by the operation. The Company has met or exceeded all the legal requirements necessary for a mining permit according to El Salvador’s mining, environmental and foreign investment laws. Despite strong local support and the inclusion of carefully engineered and reliable environmental protections for the proposed El Dorado Mine, the GOES has not met its responsibility to approve the permits necessary to advance the project to the final step of full production.

During fiscal 2013 (early June 2012), the ICSID Tribunal overseeing the Arbitration action issued its ruling on the Jurisdiction Objections filed by the GOES, wherein the GOES asserted that ICSID does not have jurisdiction to hear PacRim's claims under CAFTA or the Investment Law based largely on timing and nationality issues. In its ruling, the Tribunal determined ICSID does have jurisdiction over this claim and will hear PacRim’s claims under the Salvadoran Investment Law, but not under CAFTA. Accordingly, the Arbitration claim is now proceeding under the Investment Law alone. ICSID, a branch of the World Bank, continues to oversee this case at its headquarters in Washington, DC and the three original arbitrators continue to hear the case.

In its decision, the Tribunal rejected the GOES’s allegations that ICSID does not have jurisdiction over PacRim’s claims under the Investment Law. The Tribunal also rejected most of the GOES’s objections to the Tribunal's CAFTA jurisdiction (including rejecting the GOES’s assertion that the case constituted an “abuse of process”). However, while ruling that PacRim is in fact a US company and is part of a group of companies that has substantial business activities in the United States, the Tribunal concluded that the specific subsidiary that filed the claim does not have sufficiently “substantial” business activities in the US to allow the investment protections under CAFTA.

In October 2012, shortly after the Tribunal’s Jurisdiction Objection ruling that allowed for continuation of the Arbitration to the next and final phase, the Company signed a service and fee agreement (the “Final Phase Fee Agreement”) with its legal counsel Crowell & Moring, LLP. The Final Phase Fee Agreement provides the Company with cost certainty in regards to Arbitration-related legal fees as it proceeds through the final phase of the claim. It does not apply to ancillary Arbitration-related expenses such as court costs, expert testimony, translation services, etc., which may be significant.

The Arbitration claim is now in the final phase, wherein the merits of PacRim's claims will finally be addressed. PacRim’s Memorial (the initial, written statement of claim) was submitted to the Tribunal in late March 2013. The Memorial is supported by detailed statements of multiple expert witnesses in the fields of economic geology, mine financing, environmental science, international law and international mining law and includes a Valuation Report (the “Valuation”) of PacRim’s El Salvador properties performed by an independent business valuation expert.

Based on the March 28, 2013 Valuation, PacRim is seeking compensation in the amount of $314 million (including prejudgment interest) for its losses caused by the GOES’s breaches of the Salvadoran Investment Law.

The Tribunal has now finalized the schedule for the remainder of the final phase, with the next step being the submission of a Counter-Memorial by the GOES by January 10, 2014. Both PacRim and the GOES will then provide written rebuttals to the Tribunal, following which oral testimony will be given, likely during mid-calendar 2014. Based on these submissions and testimonies, the Tribunal will determine whether El Salvador has breached Salvadoran and international law by refusing to issue the necessary mining licenses for the El Dorado Mine. They will also determine El Salvador's monetary liability for breaching the investment protections owed to a foreign investor as per in its own laws.

A copy of the Memorial including the Valuation, and other filings related to the Arbitration, are available on the Company’s website www.pacrim-mining.com.

The El Dorado gold project is Pacific Rim’s most advanced exploration project. El Dorado has current estimated resources of 1.4 million gold equivalent ounces in the Measured and Indicated categories combined, plus a further 0.3 million gold equivalent ounces in the Inferred category (see “January 2008 Resource Estimate” above). Because the average grade of these resources (approximately 10.5 gold equivalent grams per tonne) is relatively high, the underground mine planned for the El Dorado deposits is expected to have low unit operating costs. Importantly, the El Dorado deposits are inherently environmentally clean and the production and processing is expected to have a negligible impact on the local environment. The El Dorado project has delivered many technical successes; however its path forward to development and operation has been hampered by excessively lengthy delays in the permitting process on the part of the GOES. The El Dorado project is currently the subject of an Arbitration action under the auspices of the Investment Law of El Salvador, as discussed above.

The Company drastically reduced its Salvadoran exploration expenditures during fiscal 2009, which primarily affected exploration work at the El Dorado project. The Company does not intend to contemplate resuming significant exploration work designed to advance the El Dorado project further until such time as the environmental permit is received and the exploitation concession is granted.

There are no known ore reserves on the Santa Rita property and all work programs on the property are exploratory searches for ore grade mineralization.

The Santa Rita gold property is located in central El Salvador, immediately northwest of the El Dorado project. The Santa Rita exploration licence was staked by the Company’s subsidiary PRES in July 2005 after its regional reconnaissance program in El Salvador resulted in the discovery of gold-bearing quartz-calcite boulders. During fiscal 2010, the Santa Rita exploration licence expired and was immediately re-staked by the Company’s subsidiary DOREX. DOREX is currently awaiting approval of the new Santa Rita exploration licence.

PRES discovered an epithermal quartz-calcite vein system at Santa Rita in fiscal 2006. Two distinct veins were originally discovered and surface rock channel samples collected from along the length of one of these, the 2+ kilometre long Trinidad vein, which returned anomalous gold (between 6.4 g/t gold and 118.3 g/t over vein widths of 1 to 2 meters) at various localities along its length. In late fiscal 2006 PRES received a permit from MARN to conduct a drill program on the Santa Rita gold project. However, during fiscal 2007 the Company stepped back from exploration work at Santa Rita when the project became the target of anti-mining protests. Exploration work at Santa Rita resumed during fiscal 2008 and continued into early fiscal 2009.

Notwithstanding the excellent exploration potential demonstrated to date at the Santa Rita project, exploration activities were curtailed in July 2008 in keeping with the Company’s decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted. No exploration work was undertaken by the Company at the Santa Rita property during fiscal 2013.

The foregoing disclosure has been prepared by or under the supervision of William Gehlen, Certified Professional Geologist, a Qualified Person for the purposes of NI 43-101. Mr. Gehlen is the Vice-President of Exploration of the Company. The Company’s sampling procedures follow the Exploration Best Practices Guidelines outlined by the Mining Standards Task Force and adopted by the TSX. Samples have been assayed using fire assay with a gravimetric finish on a 30-gram split. Quality control measures, including check- and sample standard-assaying, are being implemented. Samples were assayed by Inspectorate America Corporation in Reno, Nevada, an ISO 9002 certified laboratory, independent of the Company.

There are no known ore reserves on the Zamora-Cerro Colorado property and all work programs on the property are exploratory searches for ore grade mineralization.

During fiscal 2006 Pacific Rim signed an agreement to acquire a 100% interest in the Zamora gold property in El Salvador from a consortium of private companies, which was amended in fiscal 2007 to include additional exploration licences known as Cerro Colorado.

On February 11, 2010, an amendment to the Zamora-Cerro Colorado option agreement was signed by the Company and the property vendors Nycon Resources, Inc. and Cerro Colorado S.A. de C.V. (collectively, the “Optionor”). Under the terms of the amended agreement, the Company will retain is 100% option on the claims comprising the Zamora-Cerro Colorado property but will defer all further and remaining option payments to the Optionor until the earlier of February 11, 2015, or such time as the Company receives an approved mining permit for the El Dorado project (being a clear signal of the GOES’ support of the mining industry in El Salvador). All other aspects of the option agreement remain unchanged.

The schedule of advanced royalty payments required to maintain the Company’s option to purchase the Zamora-Cerro Colorado property, as per the amended agreement is:

Upon TSX approval of the amended agreement:	100,000 shares plus 100,000 warrants of the Company (shares issued)
Yearly advanced royalty payments:	The greater of:
First anniversary	100,000 shares or $100,000 in shares of the Company (shares issued)
Second anniversary	140,000 shares or $140,000 in shares of the Company (shares issued)
Third anniversary	200,000 shares or $200,000 in shares of the Company (shares issued)
Fourth payment - Payment date is earlier of the date the Company receives confirmation that the Government of the Republic of El Salvador has granted a mining exploitation concession for the El Dorado Project and February 11, 2015	300,000 shares or $300,000 in shares of the Company (option payment deferred – see above)
Fifth payment – due on anniversary of fourth payment per February 2010 amended agreement and subsequent anniversaries	400,000 shares or $400,000 in shares of the Company (option payment deferred – see above)

The above advanced royalty payment schedule applies to both the Zamora and Cerro Colorado exploration license options and supersedes the original agreement terms. As per the terms of the revised agreement, advanced royalty payments as outlined above will continue until production is achieved or the exploration concessions expire. Title to 100% of the Cerro Colorado and Zamora exploration licenses is to be transferred to Pacific Rim at such time as a positive production decision is made by the Company. Upon achievement of commercial production from the Cerro Colorado or Zamora claims, the sellers are entitled to receive a 3% net smelter royalty to a maximum of $10 million (inclusive of the dollar value of the advanced royalty payments made).

The Zamora and Cerro Colorado claims comprise a 125 square kilometre land package located 50 kilometres north of San Salvador, in El Salvador. The Company has staked additional ground between the Cerro Colorado and Zamora licences it optioned in order to cover what the Company believes is a large gold-bearing epithermal system situated on the same regional gold belt that hosts PRES’s El Dorado and Santa Rita gold systems in El Salvador and a number of million-plus ounce gold systems in Guatemala. The Company has not yet received confirmation that the licences it staked in fiscal 2008 and early fiscal 2009 have been formally granted.

Despite the positive exploration results the Company has generated to date on the Zamora-Cerro Colorado project, further exploration activities were curtailed in July 2008 in keeping with the Company’s decision to significantly reduce its investment in El Salvador until such time as the El Dorado environmental permit is received and the exploitation concession is granted. The Company’s exploration work at the Zamora-Cerro Colorado property during fiscal 2013 was limited to activities required to keep the Zamora-Cerro Colorado licences in good standing and did not include any exploration work to advance the property.

In June 2011, Pacific Rim, through its US subsidiary Pacific Rim Exploration Inc. (“PREx”) signed a Definitive Agreement with ICN Resources Ltd. (“ICN”) and Washoe Gold Inc. (“WGI”) (collectively with the Company and PREx, the “Hog Ranch Parties”) providing the Company with the option to acquire a 65% joint venture interest in the Hog Ranch property located in Washoe County, Nevada, approximately 180 km north of Reno. ICN (and its interest in the Hog Ranch property) was subsequently acquired by Corazon Gold Corp (“Corazon”).

As per the terms of the Hog Ranch Definitive Agreement, PREx has been granted the option to acquire a 65% interest (the “Interest”) in the Hog Ranch Property through the expenditure of an aggregate of $8 million in exploration expenditures and the issuance of an aggregate of 1 million common shares of Pacific Rim, with annual extensions dependent on results of exploration, according to the following schedule:

Exploration expenditures with respect to the property of up to $8.0 million as follows:

(i) 200,000 common shares of Pacific Rim within five business days of receipt of approval of the Definitive Agreement by the applicable stock exchanges (completed); and
(ii) 200,000 common shares of Pacific Rim on or before each of the second (completed), third, fourth and fifth anniversaries of the July 8, 2011 effective date.

As per the above expenditure and payment schedule, $1 million in exploration expenditures on the property was required in the 12-month period ended July 8, 2013. The Company’s board of directors determined the Company was not in a financial position to make these required exploration expenditures before the July 2013 deadline. As a result, subsequent to the end of fiscal 2013, Pacific Rim, on behalf of PREx, informed Corazon of its intent not to proceed further with its option agreement to acquire an interest in the Hog Ranch property.

During fiscal 2011, the Company, through its Panamanian subsidiary Minera Verde, signed a letter of intent with Compania Minera Clifton S.A. (“Minera Clifton”) (collectively with the Company and Minera Verde, the “Remance Parties”) to acquire a 100% interest in the Remance project located in Panama, Central America.

The Remance Parties have agreed to sign a formal option agreement (the “Formal Agreement”) granting Minera Verde the exclusive right and option (the "Option") to acquire 100% of Minera Clifton's right, title and interest in the Remance project as soon as practicable. Signing of the Formal Agreement has not been concluded at this time and is currently highly uncertain. Minera Clifton’s application for an extension to the Remance concession term, as provided by Panamanian law, was recently denied; a decision which is currently being appealed by Minera Clifton. While the Company is keeping the Remance LOI in effect during Minera Clifton’s appeal, the outcome of this process, and hence the Company’s final acquisition of the Remance project, is highly uncertain. If signed, the Formal Agreement will be subject to all required regulatory approvals, including the approval of the Toronto Stock Exchange (the “TSX”). The option to acquire Remance may be exercised by the Company by completing the following terms:

1. paying to Minera Clifton the sum of $200,000 (the "Cash Payment"), payable as follows:

2. on the date of execution of the Formal Agreement, issuing to Minera Clifton a total of 5 million common shares of Pacific Rim (the "Acquisition Shares");

3. within the Option Period (as defined below), conducting a drilling program on the Concession of at least 10,000 metres, and initiating environmental and metallurgical studies on the Remance project (collectively, the "Drilling Program"). The Option Period is the period which begins on the date on which Pacific Rim has received all required permissions and approvals of the Panamanian government to begin the Drilling Program, and which ends on the date which is 12 months thereafter; and

4. on or before the date which is 10 days after the last day of the Option Period, giving written notice to Minera Clifton that it intends to exercise the Option, in consideration of which Pacific Rim will pay to Minera Clifton, as soon as practicable thereafter, the sum of $5,000,000, payable, at the election of Minera Clifton, in cash or common shares of Pacific Rim (the "Additional Shares").

The Company’s current knowledge of the Remance project suggests a thorough and systematic drill program is warranted to test the depth extent of the known near-surface gold mineralization (the Company would be obliged, as per the terms of the Remance, to conduct a 10,000 meter drill program on Remance in the first year of the Option Period as described above). A first phase exploration program, including environmental and metallurgical studies as well as drilling, is expected to cost approximately $1 million. The Company would require additional financing to complete its Remance exploration obligations.

Pacific Rim’s project generation initiatives focus on acquiring projects the Company believes have good exploration potential without incurring onerous costs. The Company focuses on low-sulfidation epithermal gold systems, which are environmentally clean, high grade, and have potentially low cost production, and continuously evaluates and seeks to acquire new project opportunities that fit its exploration criteria and meet its high standards.

In recent years, the Company shifted the focus of its grassroots exploration initiatives out of El Salvador to other jurisdictions that have similarly prospective mineral potential but a more robust appreciation of the economic benefits of the mining industry. Using its unique understanding of epithermal gold systems in the Central American Gold Belt, particularly within El Salvador, Pacific Rim has been very successful in locating new, high grade gold-bearing systems in the past and is ideally equipped to apply this formula for discovery to neighbouring jurisdictions and elsewhere along the Pacific Rim. While the Company continues to seek additional high quality projects that fit its exploration focus, there are no guarantees that any project generation initiatives currently underway will result in a positive outcome or that the Company will be successful in acquiring any of new projects.

US operations are subject to federal, state and local environmental laws and regulations. While the Company currently has no active US operations, its US interests during fiscal 2013 included the Hog Ranch property (an early-stage exploration property), and its prior partial ownership of the Denton-Rawhide operation remains.

Contractors to the Company are required to use certified, non-polluting, non-toxic additives in drilling programs and comply with OSHA work and safety standards and procedures. These issues are routinely monitored by Company employees.

As a result of the Company’s due diligence investigation prior to signing the Hog Ranch Definitive Agreement, the Company does not believe that in optioning the property it inherited any significant reclamation liability stemming from prior operations. Gold mining operations were conducted on the Hog Ranch property in the 1990’s. However, previous operators reclaimed all prior workings to regulatory-approved conditions including partially backfilling the open pits. The terms of the Hog Ranch Definitive Agreement preclude any environmental liability for Pacific Rim stemming from these prior operations.

The Company’s exploration programs undertaken at Hog Ranch during previous fiscal periods consisted of re-mapping the surface geology and a soil sampling program over previously un-sampled ranch lands. Environmental risks associated with exploration programs the Company undertook at Hog Ranch during fiscal 2013 relate primarily the handling and storage of fuel. There were no surface impacts as a result of work conducted by the Company during its tenure at Hog Ranch.

Subsequent to the end of fiscal 2013 the Company terminated its interest in the Hog Ranch property and has no further interest or rights in the project, nor any reclamation or other environmental liabilities with the State of Nevada, the Bureau of Land Management, nor the Hog Ranch property vendors.

During fiscal 2009 the Company sold its 49% interest in the Denton-Rawhide operation to its joint venture partner, Kennecott-Rawhide Mining Company ("Kennecott"). At the time of this sale, future reclamation costs were estimated to be $5.3 million. Subsequently, in late calendar 2010, Kennecott sold its 100% interest in the Denton-Rawhide Joint Venture to a third party. According to the terms of Kennecott's 2010 sale, reclamation obligations at the Denton-Rawhide operation were separated such that Kennecott remains responsible for reclamation expenditures due to any disturbances created prior to the sale, and the purchaser becomes responsible for undertaking reclamation related to any disturbances created after the sale. As part of the sale of its interest in Denton-Rawhide to Kennecott, the Company had provided a guarantee on 49% of any reclamation and closure costs in the event that these expenditures (limited to those related to disturbances made up to the point the Company sold its interest in the operation) were to exceed $7.0 million. In other words, the Company's obligations are limited to pre-sale property conditions.

A reclamation and closure plan for Denton-Rawhide, covering the period ending with the Company’s sale of its 49% interest in the operation to Kennecott, has been submitted to the Bureau of Land Management and the Nevada Department of Environmental Protection and is currently awaiting approval. Kennecott, on behalf of the Rawhide Joint Venture, has posted surety bonds as required for compliance with state and local closure, reclamation and environmental obligations. Estimated future reclamation and property closure costs for Denton-Rawhide are based on current legal and regulatory requirements. Actual costs incurred for reclamation activities in future periods could differ from the amounts estimated. Additionally, future changes to environmental laws and regulations could affect the extent of reclamation and remediation work required to be performed by the Company. Any such changes in future costs could materially impact the amounts charged to operations for reclamation and remediation.

The Company’s international exploration properties, currently located in El Salvador, are governed by existing local environmental laws, though the Company elects in certain circumstances to exceed its obligations under local environmental law and comply with internationally accepted environmental standards.

The Company’s exploration programs are designed according to industry best practices to have minimal to no impact on flora, fauna and surface or underground water sources. Temporary disturbances (temporary access roads, drill pads, mud pits, hand dug trenches, impacts on existing infrastructure) are reclaimed and repaired. Using the same methods required for structural studies at dam site and large construction sites, drill holes are capped with either a 50 meter grout cap or are completely filled with grout, depending on the geologic environment. The temporary access trails, drill pads and mud sumps are reclaimed by filling in ruts, holes and pits, re-contouring any banks or steep cuts, building water diversion ditches to control runoff and planting fast growing, native grasses to stabilize the ground. Trenches are refilled and replanted in a like manner, and fence barriers are occasionally built to control livestock movement around reclaimed areas. Permanent or long term disturbances such as roads, buildings, wells, walls and fences, gates, etc. are constructed with erosion controls and stability measures including, as necessary, "badenes", rock retaining walls, water diversion ditches, drain pipes and/or stabilizing vegetation, and are constructed to standards exceeding local regulation. Often, local tree varieties are harvested then replanted in the disturbed areas when it does not conflict with normal local usage. All areas of reclamation and construction are monitored on an annual basis. If additional repair is required because of the initial construction, it is repaired until the area gains stability. The Company’s professional environmental staff has volunteered and assisted the local authorities in evaluating other arms-length environmental, geologic, hydrologic, disaster sites around the immediate communities by conducting land slide analysis, ground water studies, surface water studies, land fill site studies, helping to evaluate other industrial waste sites, fire prevention, disease control, disaster relief preparedness and first aid.

Contractors to the Company are required to use certified, non-polluting, non-toxic additives in drilling programs and comply with international work and safety standards and procedures. These issues are routinely monitored by Company employees under the direction of the local environmental and safety managers. Environmental compliance and risk are regularly assessed by third party contractors specializing in mining and exploration risk management. In addition, the Company has established showcase programs for environmental protection, waste management and reforestation in order to educate workers and local populace on common best practice measures for a healthier, cleaner and safer living and working environment.

Ongoing reclamation activities associated with the Company’s exploration stage properties are expensed as exploration in the period incurred.

Pacific Rim is continually reviewing potential project acquisitions and other opportunities that could enhance shareholder value.

Other than the potential Remance project acquisition, which if completed, will involve payments of cash and shares, there are currently no transactions in process that would affect the financial condition, results of operations or cash flows of the Company.

The Company’s financial statements have been prepared in accordance with IFRS as issued by the International Accounting Standards Board (“IASB”). Prior to adopting IFRS at the commencement of fiscal 2012, the Company’s financial statements were prepared in accordance with Canadian generally accepted accounting principles as set out in the Handbook of the Canadian Institute of Chartered Accountants (“CICA Handbook”).

The following policies are considered by management to be essential to understanding the processes and reasoning that go into the preparation of the Company’s financial statements and the uncertainties that could have a bearing on its financial results. Readers are encouraged to review Note 3 of the Company’s fiscal 2013 audited consolidated financial statements for a thorough description of all accounting policies.

The Company capitalizes the direct costs of acquiring mineral property interests including option payments, until such time as the property is put into production or the property is disposed of, either through sale or abandonment or becomes impaired. If a mineral property is put into production the costs of acquisition are expensed over the life of the property based on estimated economic reserves. Proceeds received from the sale of any interest in a property will be credited against the carrying value of the property with any difference recognized in the statement of loss and comprehensive loss. If a property is abandoned, the acquisition costs will be written off to the statement of loss and comprehensive loss.

Exploration and evaluation costs are charged to operations in the period incurred until such time as it has been determined that a property has economically recoverable reserves, in which case subsequent exploration and development costs are capitalized. Exploration costs include value-added taxes because the recoverability of these amounts are uncertain.

Ownership in mineral properties involves certain inherent risks due to the difficulties of determining and obtaining clear title to claims as well as the potential for problems arising from the frequently ambiguous conveyance history characteristics of many mineral properties. The Company has investigated ownership of its mineral properties and, to the best of its knowledge, ownership of its interests are in good standing.

The carrying amounts of non-financial assets are reviewed for impairment whenever facts and circumstances suggest that the carrying amounts may not be recoverable. If there are indicators of impairment, the recoverable amount of the asset is estimated in order to determine the extent of any impairment. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units or CGUs). The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use (being the present value of the expected future cash flows of the relevant asset or CGU). An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount.

Non-financial assets that have been impaired in prior periods are tested for possible reversal of impairment whenever events or changes in circumstances indicate that the impairment has reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount but not beyond the carrying amount that would have been determined had no impairment loss been recognized for the asset in the prior periods. A reversal of an impairment loss is recognized in the statement of loss.

The preparation of the consolidated financial statements requires estimates and assumptions that affect the amounts reported in the consolidated financial statements. Significant areas where judgment is applied include, going concern assumption and assessment of whether there are any indicators of impairment over mineral property interests. Significant areas where estimates are applied include the recoverability of mineral property costs, valuation of warrant derivatives, and estimates with respect to recognition of potential obligations and liabilities. Actual results could differ from our estimates and readers are encouraged to thoroughly review Note 4 of the Company’s fiscal 2013 audited consolidated financial statements.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and further periods if the review affects both current and future periods.

The following are considered critical accounting estimates and judgements used in the preparation of the Company’s financial statements for fiscal 2013.

The net carrying value of each mineral property is reviewed regularly for conditions that suggest impairment. This review requires significant judgment as the Company does not have any proven and probable reserves that enable estimated future cash flows to be compared to the carrying values. Factors considered in the assessment of asset impairment include, but are not limited to, whether there has been a significant decrease in the market price of the property; whether there has been a significant adverse change in the legal, regulatory, accessibility, title, environmental or political factors that could affect the property’s value; whether there has been an accumulation of costs significantly in excess of the amounts originally expected for the property’s acquisition, development or cost of holding; whether exploration activities produced results that are not promising such that no more work is being planned in the foreseeable future and whether the Company has the necessary funds to be able to maintain its interest in the mineral property.

Certain new standards, interpretations, amendments and improvements to existing standards were issued by the International Accounting Standards Board (“IASB”) or International Financial Reporting Interpretations Committee (“IFRIC”). The Standards impacted that are applicable to the Company are as follows:

For fiscal year ended April 30, 2013 compared to fiscal year ended April 30, 2012

For the fiscal year ended April 30, 2013, Pacific Rim recorded a loss of $(4.7) million or $(0.02) per share, compared to a loss of $(1.8) million or $(0.01) per share for the fiscal year ended April 30, 2012. The increase in net loss for fiscal 2013 compared to fiscal 2012, despite decreased expenses for exploration activity, stock-based compensation and professional services, is primarily related to a substantial increase in costs related to the Arbitration year over year as well as substantially less gains on the Company’s derivative liability in fiscal 2013 compared to fiscal 2012.

Due to a decrease in the level of exploration activity at the Hog Ranch property during the past fiscal year, exploration expenditures were lower in fiscal 2013 than in fiscal 2012 ($1.5 million and $1.8 million, respectively).

General and administrative expenses were relatively stable year over year ($0.4 million for fiscal 2013 compared to $0.5 million for fiscal 2012) as were costs related to stock-based compensation ($0.4 million for fiscal 2013 compared to $0.5 million for fiscal 2012). Costs related to professional services decreased slightly year over year ($0.2 million for fiscal 2013 compared to $0.3 million for fiscal 2012) reflecting the Company’s reduced business activity.

Arbitration-related expenses totalled $2.0 million during fiscal 2013 compared to $0.5 million during fiscal 2012. This increase reflects the substantial activity undertaken during the current year related to preparation and submission of the Memorial (see “Mineral Properties” – El Dorado Property – Arbitration Action, above).

Gains on derivative liability (income related to changes in the term to expiry and fair value of common stock warrants issued by the Company during private placement financings) decreased substantially year over year, from $2.1 million during fiscal 2012 to $0.2 million during fiscal 2013) reflecting decreases in the Company’s share price and the expiration of a majority of the Company’s outstanding warrants.

As a result of increased Arbitration-related expenses and substantially lower gains on the Company’s derivative liability, the Company’s loss for fiscal 2013 was $(4.7) million or $(0.02) per share compared to $(1.8) million or $(0.01) per share for fiscal 2012.

For fiscal year ended April 30, 2012 compared to fiscal year ended April 30, 2011

For the fiscal year ended April 30, 2012, Pacific Rim recorded a loss of $(1.8) million or $(0.01) per share, compared to a loss of $(3.8) million or $(0.03) per share for the fiscal year ended April 30, 2011. The decrease in net loss for fiscal 2012 compared to fiscal 2011, despite increased exploration and general and administrative expenses, is primarily related to substantially increased gains on the Company’s derivative liability in fiscal 2012 compared to fiscal 2011, as well as a decrease in costs related to the Arbitration year over year.

Due to the commencement of exploration at the Hog Ranch property in late fiscal 2011, exploration expenditures were higher in fiscal 2012 than in fiscal 2011 ($1.8 million and $1.2 million, respectively).

General and administrative expenses were stable year over year ($0.5 million in both fiscal 2011 and fiscal 2012) though the Company did realize slight increases in stock-based compensation ($0.3 million in fiscal 2011 compared to $0.5 million in fiscal 2012 and professional services ($0.2 million in fiscal 2011 compared to $0.3 million in fiscal 2012) due to the slightly higher level of business activity undertaken by the Company during fiscal 2012.

Arbitration-related expenses totaled $0.5 million during fiscal 2012 compared to $0.3 million during fiscal 2011, a slight increase attributable to costs associated with the Jurisdiction Objection hearings held in early fiscal 2012.

The Company booked a small foreign exchange loss of $0.1 million during fiscal 2012 compared to a foreign exchange gain of $0.1 million during fiscal 2011, primarily reflecting the impact of the US-Canadian dollar exchange rate on the Company’s Canadian dollar-denominated investments on hand.

As a result of increased exploration expenditures, general and administrative costs and Arbitration-related expenses, offset by substantially increased gains on the Company’s derivative liability, the Company’s loss for fiscal 2012 was reduced to $(1.8) million or $(0.01) per share from $(3.8) million or $(0.03) per share for fiscal 2011.

Summary of Quarterly Results (unaudited)(all amounts in thousands of US dollars, except per share amounts)

The Company typically incurs a net quarterly loss. Exploration expenses have been relatively stable over the past 8 quarters. Legal expenses related to the Arbitration action, which commenced in early fiscal 2010, are periodically higher commensurate with the level of activity related to the action. Consequently expenses, which impact net loss and comprehensive loss, have occasionally spiked during certain of the last eight quarters including Q2, Q3 and Q4 2013 when documents related to the final phase of the Arbitration were under preparation. During all of fiscal 2012 and the first and third quarters of fiscal 2013, the Company booked gains on its derivative liability, which in Q1 2012 was substantial enough to offset expenses and result in income for the period. During the past three quarterly periods (Q2, Q3 and Q4 2013) all of the Company’s outstanding warrants expired. This substantially reduced gains on derivative liability during Q4 2013 and resulted in a small loss on derivative liability during Q2 2013, the result of which was an increase in Loss and Comprehensive Loss for both periods. The results of operations for each of the past eight quarterly periods are not affected by seasonal trends and are largely a function of the relative impact of exploration, general and administrative and Arbitration action expenses realized during each quarter as well as gains or losses on the Company’s derivative liability.

Net loss for the three months ended April 30, 2013 was $(1.9) million compared to $(0.3) million in the three month period ended April 30, 2012. This increase in net loss for Q4 2013 compared to Q4 2012 is a result of two primary factors: a substantial increase in expenses related to the Arbitration ($1.2 million for Q4 2013 compared to $0.2 for the same period a year earlier), which reflects the significant work done during the last quarter of fiscal 2013 in preparation and submission of the Memorial; and a decrease in gains on derivative liability from $0.5 million during Q4 2012 to a nominal amount during Q4 2013.

The Company’s operations are primarily focused on the exploration for gold and silver and its sole material project, the El Dorado property, is located in El Salvador. The Company has experienced significant delays in the receipt of environmental and mining permits necessary to advance the El Dorado project further. See Item 4D – “Property, Plant and Equipment”, and specifically “El Salvador Mining Regime” and “El Dorado Property – Arbitration Claim” for information related to El Salvador’s mining law, the Company’s actions to date to comply with this law and an Arbitration claim that the Company’s US subsidiary, Pac Rim Cayman LLC, has commenced with the International Center for the Settlement of Investment Disputes in Washington, DC. The receipt of necessary permits, or lack thereof, could have a material impact on the Company’s operations.

For fiscal year ended April 30, 2013 compared to fiscal year ended April 30, 2012

During fiscal 2013 the Company’s cash increased by $0.1 million from $0.8 million at April 30, 2012 to $0.9 million at April 30, 2013. Short-term investments were unchanged year over year ($0.5 million at both April 30, 2013 and April 30, 2012). As a result assets were unchanged year over year ($7.0 million at both April 30, 2013 and April 30, 2012). The Company’s current asset position at April 30, 2013 reflects the proceeds of a private placement equity financing that closed during the fiscal year, less cash spent on exploration, expenditures related to the Arbitration and general and administrative costs associated with maintaining a public company.

The Company’s financial statements have been prepared on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its commitments, continue operations, realize its assets and discharge its liabilities in the normal course of business for the foreseeable future. There are events and conditions that cast substantial doubt on the validity of that assumption. The Company will require additional financing in the near future for general working capital purposes and for legal expenses related to the Arbitration. Furthermore, as the Company does not have a source of revenue, it will require ongoing financing in the future for working capital and general and administrative purposes, in order to conduct any future exploration programs. The costs for the Arbitration are substantial and are anticipated to increase in mid-fiscal 2014 as the case proceeds through the final, merits-based phase with additional written and oral testimony. While the Company has entered into a service and fee agreement with its Arbitration legal counsel that provides legal fee cost certainty through the final phase, additional Arbitration-related costs including but not limited to costs related to expert witness testimony, that fall outside of the service and fee agreement, will be incurred, and along with ongoing general and administrative and regulatory expenses, will necessitate additional financing in the future. Factors that could affect the availability of financing include fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application. The Company believes it will be able to obtain the necessary financing to meet its requirements on an ongoing basis; however, there can be no assurance that the necessary financing will be obtained, and such financing, if available, may be very dilutive to the Company’s shares and shareholders. As it has in the past, the Company plans to obtain additional financing through, but not limited to, the issuance of additional equity.

The Company’s net loss for fiscal 2013 was $(4.7) million compared to $(1.8) million for fiscal 2012. These losses were offset by a number of non-cash items including, notably: unrealized gains on derivative liability of $(0.2) million in fiscal 2013 compared to $(2.1) million in fiscal 2012; stock-based compensation of $0.4 million in fiscal 2013 compared to $0.5 million in fiscal 2012; and accounts payable and accrued liabilities of $0.3 million in fiscal 2013 compared to a marginal amount in fiscal 2012. Although the fiscal 2013 loss from continuing operations was substantially higher than in fiscal 2012, unrealized gains from the Company’s derivative liability, a non-cash item, were substantially lower year over year. As a result, cash flow used for operating activities during fiscal 2013 was $0.8 million higher than in fiscal 2012 ($(4.1) million and $(3.3) million, respectively) reflecting increased cash expenditures related to the Arbitration.

During fiscal 2013 the Company made net purchases of short term investments of $(1.9) million compared to $(1.6) million during fiscal 2012. Redemption of short term investments added $1.8 million to cash during both fiscal 2013 and fiscal 2012. Negligible purchases of property plant and equipment were made in fiscal 2012 compared to $nil in fiscal 2013. As a result, cash flow provided by (used for) investing activities was $(0.1) million during fiscal 2013 compared to $0.2 million during fiscal 2012.

The Company realized $4.2 million in cash flow from financing activities during fiscal 2013, compared to $3.6 million during fiscal 2012. The fiscal 2013 and fiscal 2012 financing cash flow amounts are related to the issuance of common shares of the Company under two private placement equity financings that closed in October 2012 and May 2011 respectively (details below).

During fiscal 2013, the Company closed a non-brokered private placement financing in which a single subscriber, OceanaGold Corporation, purchased 42,150,000 common shares of the Company at CAD $0.10 per share, for total proceeds of CAD $4,215,000. No warrants were issued and no finder’s fees were paid in connection with this financing.

During fiscal 2012, the Company closed a private placement financing (previously announced in late fiscal 2011) in which gross proceeds of CDN $3,696,000 were raised through the issuance of 17,600,000 Units at a price of CDN $0.21 per Unit. Each Unit issued in the fiscal 2012 financing consists of one common share in the Company and one half of one share purchase warrant that entitles the holder to acquire one additional common share of the Company at a price of CDN $0.30 for a period of 24 months following the closing of the financing. Pacific Rim reserves the right to accelerate the exercise period of the fiscal 2012 financing warrants should its common stock trade above CDN $0.50 for 20 consecutive trading days. The Company also issued 233,400 Units to certain finders in connection with the private placement, in payment of a finder’s fee of 6% of the proceeds raised from subscribers introduced by the finders, and issued 716,400 warrants to finders representing 6% of the total number of Units sold to purchasers introduced by the finders.

For fiscal year ended April 30, 2012 compared to fiscal year ended April 30, 2011

During fiscal 2012 the Company’s cash increased by $0.5 million from $0.3 million at April 30, 2011 to $0.8 million at April 30, 2012. Short-term investments decreased year over year from $0.8 million at April 30, 2011 to $0.5 million at April 30, 2012. As a result of the increase in cash and the decrease in short-term investments, current assets increased by $0.2 million year over year from $1.2 million at April 30, 2011 to $1.4 million at April 30, 2012. This modest increase reflects the proceeds of a private placement equity financing that closed during fiscal 2012, less cash spent on exploration expenses and project generation efforts, general and administrative costs associated with maintaining a public company, and expenditures related to the Arbitration.

The Company’s loss from continuing operations was $(1.8) million in fiscal 2012 compared to $(3.8) million in fiscal 2011. These losses were offset by a number of non-cash items including, notably: stock-based compensation of $0.5 million in fiscal 2012 compared to $0.3 million in fiscal 2011; gains from the Company’s derivative liability of $(2.1) million in fiscal 2012 compared to $(0.2) million in fiscal 2011; and a marginal decrease in accounts payable and accrued liabilities in fiscal 2012 compared to $0.1 million in fiscal 2011. Although the fiscal 2012 loss from continuing operations was substantially lower than in fiscal 2011, gains from the Company’s derivative liability, a non-cash item, were substantially higher year over year. As a result, cash flow used for operating activities during fiscal 2012 was only $0.4 million lower than in fiscal 2011 ($(3.3) million and $(3.7) million, respectively).

During fiscal 2012 the Company made net purchases of short term investments of $(1.6) million compared to $(1.0) million during fiscal 2011. Redemption of short term investments added $1.9 million to cash during fiscal 2012 compared to $0.3 million during fiscal 2011. Negligible purchases of property plant and equipment were made in fiscal 2012 compared to $nil in fiscal 2011. As a result, cash flow provided by (used for) investing activities was $0.2 million during fiscal 2012 compared to $(0.7) million during fiscal 2011.

The Company realized $3.7 million in cash flow from financing activities during fiscal 2012, compared to $3.3 million during fiscal 2011. The fiscal 2012 and fiscal 2011 financing cash flow amounts are related to the issuance of common shares of the Company under two private placement equity financings that closed in May 2011 and October 2010 respectively (details below).

The fiscal 2012 private placement financing is described above under Cash Flow Provided by Financing Activities for the fiscal year ended April 30, 2013 compared to the fiscal year ended April 30, 2012.

During fiscal 2011, the Company announced and closed a private placement financing in which a total of CDN $3,332,000 was raised through the issuance of 19,600,000 Units. Each Unit issued in the fiscal 2011 financing consists of one common share in the Company and one half of one share purchase warrant that entitles the holder to acquire one additional common share of the Company at a price of CDN $0.30 for a period of 24 months following the closing of the financing, which occurred on October 8, 2010. Pacific Rim reserves the right to accelerate the exercise period of the fiscal 2011 financing warrants should its common stock trade above CDN $0.50 for 20 consecutive trading days. The Company also issued 660,000 Units to certain finders in connection with the private placement, in payment of a finder’s fee of 6% of the proceeds raised from subscribers introduced by the finders, and issued 660,000 warrants to finders representing 6% of the total number of Units sold to purchasers introduced by the finders.

Working Capital - For fiscal year ended April 30, 2013 compared to fiscal year ended April 30, 2012

At April 30, 2013, the Company had current assets of $1.5 million, compared to $1.4 million at April 30, 2012, an increase of $0.1 million. The slight increase in current assets is primarily a result of cash raised through private placement financings in both fiscal 2013 ($4.2 million) and fiscal 2012 ($3.7 million) and subsequent expenditures of cash on exploration, general and administrative and Arbitration-related expenses. Resource property balances at April 30, 2013 were marginally lower than the April 30, 2012 balances ($5.45 million $5.49 million respectively).

At April 30, 2013 the Company had current liabilities of $2.0 million, compared to $1.6 million at April 30, 2012. Of the accounts payable and accrued liability balances, $1.6 million at April 30, 2013 and $1.4 million at April 30, 2012 is due to one vendor associated with the Arbitration.

The $0.1 million increase in current assets combined with the $0.4 million increase in current liabilities, resulted in a $0.3 million increase in the working capital deficit from $(0.2) million at the end of fiscal 2012 to $(0.5) at the end of fiscal 2013.

Working Capital – For fiscal year ended April 30, 2012 compared to fiscal year ended April 30, 2011

At April 30, 2012, the Company had current assets of $1.4 million, compared to $1.2 million at April 30, 2011, an increase of $0.2 million. The slight increase in current assets is primarily a result of cash raised through a private placement financing in early fiscal 2012 and subsequent expenditures of cash on exploration, general and administrative and Arbitration-related expenses. Resource property balances at April 30, 2012 were marginally higher than the April 30, 2011 balances ($5.49 million $5.45 million respectively).

At both April 30, 2012 and April 30, 2011 the Company had current liabilities of $1.64 million. Of the accounts payable and accrued liability balances, $1.4 million at April 30, 2012 (compared to $1.4 million at April 30, 2011) is due to one vendor associated with the Arbitration.

The $0.2 million increase in current assets combined with no change in current liabilities, resulted in a $0.2 million improvement in working capital from $(0.4) million at the end of fiscal 2011 to $(0.2) at the end of fiscal 2012.

The Company does not intend to resume significant exploration programs in El Salvador until such time as the El Dorado environmental permit and exploitation concession are received. The Company cannot judge if or when the required permits will be received and is not currently planning any exploration programs for its El Dorado, Santa Rita and Zamora-Cerro Colorado properties for the immediate future beyond what is necessary to maintain its exploration licences. Should the required permits be granted, the Company will evaluate its options for resuming full scale exploration work designed to advance its El Salvador projects.

Acquisition of the Remance project is in doubt and therefore, no exploration plans for Remance are being contemplated at this time. However, if a final acquisition agreement on Remance is signed, as per the terms of the Remance LOI the Company will be responsible for undertaking a $1 million exploration program in the first year of the option period. The Company intends to continue its project generation initiatives with the aim of evaluating and possibly acquiring new exploration properties of merit that fit its exploration focus. Minimal expenditures are anticipated for generative exploration work in the coming fiscal year. The Company will require additional financing in order to carry out any other future exploration work of a substantive nature.

The Company’s general and administrative costs are expected to decrease slightly during fiscal 2014 as every effort is made to trim costs where possible, including recent reductions in staffing expenditures. Expenditures related to PacRim’s Arbitration claim are expected to vary widely through fiscal 2014 as each party prepares and submits its written testimonies in turn. The Company has currently accumulated a liability of approximately $1.4 million related to the Arbitration. Additional working capital (likely through equity financing) will be required to fund ongoing general and administrative costs. Though the Company has signed a service and fee agreement with its Arbitration legal counsel that will preclude legal fee cost overruns, ancillary Arbitration-related expenses such as expert witnesses, court costs, etc. are less certain and may be substantial.

The business of mining and exploration involves a high degree of risk and there can be no assurance that any of the Company’s current exploration projects will result in profitable mining operations. The Company has no source of revenue, and will require additional cash in the future to fund exploration and administrative expenses. As at April 30, 2013, the Company has negative working capital of $(0.5) million, has incurred losses since inception and has an accumulated deficit of $(94.5) million. The Company’s ability to continue operations and exploration activities as a going concern is dependent upon its ability to obtain future financing. The Company will need to raise additional funds to support exploration and administration expenses and to support expenses related to the Arbitration action that fall outside of its legal services agreement. While the Company has been successful in obtaining financing in the past, there is no assurance that sufficient funds will be available to the Company, or be available on favourable terms in the future. Furthermore, given the Company’s recent share price and the current state of equity markets, such financing, if available, may be very dilutive to the Company’s shares and shareholders. Factors that could affect the availability of financing include fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application. Additional financing will require, but may not be limited to, the issuance of additional equity.

While no substantial exploration programs are envisioned at this time for fiscal 2014, the Company will undertake work and make various expenditures required to keep all of its exploration projects in good standing. As a result of the termination of the Hog Ranch option and recent cuts to exploration and support staff, exploration-related expenditures for fiscal 2014 are expected to be lower than in fiscal 2013, and total approximately $1.0 million. The Company will require additional financing in fiscal 2014 to meet its anticipated exploration expenses.

The Company will continue to curtail its exploration programs and expenditures in El Salvador until such time as PRES receives the El Dorado environmental permit and exploitation concession. The Company remains hopeful that it will either receive the El Dorado permit and mining concession or that it will be appropriately compensated. The Company will continue to seek opportunities for dialogue with the GOES aimed at resolving its permitting issues in El Salvador including receipt of the environmental and mining permits for the El Dorado project as well as re-establishing the exploration licence for Santa Rita.

The Company’s acquisition of the Remance property is on hold and highly uncertain at this time, pending the vendor’s legal appeal of the Government of Panama’s recent decision to deny extension of the Remance concession term. While the Company is keeping the Remance LOI in effect during Minera Clifton’s appeal, it does not intend to consider signing a final agreement to acquire the Remance project unless the term of the concession is extended.

The Company continues to monitor new project opportunities in North and Central America.

As a result of recently adopted measures aimed at reducing its staffing costs, the Company’s general and administrative costs are expected to be marginally reduced during fiscal 2014. Additional working capital (likely through equity financing) will be required in the future to fund ongoing general and administrative costs. Expenditures related to the Arbitration claim are expected to be substantial as the case proceeds through the final phase. Though the Company has signed a service and fee agreement with its Arbitration legal counsel that will preclude legal fee cost overruns, ancillary Arbitration-related expenses such as expert witnesses, court costs, etc. are less certain and may be substantial.

The Company will continue to seek opportunities for dialogue with the GOES aimed at resolving the El Dorado permitting situation. The Company and its subsidiaries have a well-documented history of supporting local inhabitants and building relationships with all stakeholders. This is a key component of the Company’s approach to exploration and development, and will continue in all jurisdictions in which it and its subsidiaries operate.

Unless these diplomatic efforts are successful, the Arbitration action is expected to proceed during fiscal 2014 and beyond. Having submitted its Memorial in late fiscal 2013, the Company and its legal counsel are currently awaiting the GOES’s submission of its Counter-Memorial anticipated in January 2014. This submission will be followed by oral testimony by both parties before the Tribunal. Based on these submissions and testimonies, the Tribunal will determine whether El Salvador has breached Salvadoran and international law by refusing to issue the necessary mining licenses for the El Dorado Mine. They will also determine El Salvador's monetary liability for breaching the investment protections owed to a foreign investor as per in its own laws. The final phase of the Arbitration case is expected to continue through fiscal 2014 and potentially beyond.

Important corporate and technical issues facing the Company in the coming fiscal year (and beyond) include: developments related to the Arbitration action; ongoing efforts to reach a resolution to the El Dorado permitting impasse with the GOES; the Company’s ability to secure adequate future financing for ongoing Arbitration-related costs, general working capital purposes, and exploration expenses including maintenance of the El Salvador properties; developments related to the potential signing of a formal option agreement to acquire the Remance project and the subsequent undertaking of an exploration and drilling program at Remance if, as, and when it is formally acquired; and, the continued search for additional exploration project opportunities. The Company has been successful in raising funds through equity financing in the past but there can be no assurance that such financing will be available in the future, or if so, available under favourable terms.

While the Company does not have any producing mines, it is directly affected by trends in the metal industry. The Company’s principal assets are its gold exploration properties, one of which comprises several known gold deposits. The global economic and credit crisis has affected all industries, including mining, and has resulted in additional pressure on the ability and costs of obtaining project capital financing. Global metal prices, driven by rising global demand, climbed dramatically and approached historic highs over the past several years but are volatile and subject to periodic corrections as has happened in the past several months. The effect of high metal prices had a significant positive impact on the ability to raise equity capital, which has resulted in increases in global exploration projects and in turn has caused the procurement of exploration services and skilled employees to be increasingly difficult. In recent months however, decreased global metal prices and especially decreases in the gold price, have reduced market appetite for equity issues and access to capital is more difficult than in recent years.

Overall market prices for securities in the mineral resources sector and factors affecting such prices, including base metal prices, political trends in the countries such companies operate, and general economic conditions, may have an effect on the terms on which financing is available to the Company, if at all.

Refer to “Risk Factors” for further information on uncertainty or items affecting the business or nature of business of the Company.

The Company’s stock option awards normally vest as follows: 1/3 upon the date of grant; 1/3 upon the first anniversary of the grant date; and 1/3 upon the second anniversary of the grant date. During the period from May 1, 2012 to April 30, 2013, the following options vested: the last third of options granted on to the NEOs on December 17, 2012; the second third of options granted on September 29, 2012; and the first third of options granted on October 4, 2012.

In 2006 the Company established an Evergreen Incentive Stock Option Plan (the “Evergreen Plan”), which was initially approved by the shareholders of the Company (the “Shareholders”) on August 29, 2006 and reapproved by Shareholders on August 26, 2009 and September 6, 2012.

The following is only a summary of certain provisions of the Evergreen Plan and is qualified in its entirety by the provisions of the Evergreen Plan. A Shareholder or other interested party may obtain a copy of the Evergreen Plan by contacting the Corporate Secretary of the Company in writing at Suite 1050, 625 Howe Street, Vancouver, British Columbia, V6C 2TC or by telephone at 604-689-1976.

On September 6, 2012, Shareholders reapproved the Company's Evergreen Plan, which was initially adopted in 2006 and reapproved in 2009. The Evergreen Plan is designed to attract and retain highly qualified employees, service providers, consultants, directors and officers of the Company and its subsidiaries (collectively, the “Eligible Participants”). The method of establishing the maximum number of shares reserved for grant under option is equal to 10% of the number of shares outstanding at the time of grant. All of the Company’s outstanding options, including those currently granted to the NEOs as well as to the directors, employees and consultants of the Company are governed by the Evergreen Plan, as all options granted under the Company’s former 2002 incentive stock option and stock bonus plan have expired, been exercised or cancelled.

Under the Evergreen Plan, the Board of Directors is authorized to designate Eligible Participants to whom options should be granted. As well, the directors have the power under the terms of the Evergreen Plan to appoint a committee of not less than three (3) directors to administer the Evergreen Plan. The exercise price for an option granted under the Evergreen Plan shall be determined by the directors at the time of grant, provided such price shall not be less than the "market price", being the volume weighted average trading price for the five trading days immediately preceding the date of grant. The Company presently does not have a share purchase plan and does not grant stock appreciation rights.

The Board of Directors fixes the vesting terms which it deems appropriate when options are granted. On a “change of control” (as defined in the Evergreen Plan), all shares subject to outstanding options will become vested and exercisable by the optionees. Options granted under the Evergreen Plan have a maximum fixed term of ten (10) years, subject only to the expiration date of the fixed term falling within, or immediately after, a blackout period that was self-imposed by the Company, in which case the option will expire within a 10 business day period after the blackout is lifted. No option may be assigned other than by will or pursuant to the laws of succession, and to a trust, RESP or RRSP or similar legal entity established by the optionee.

The Evergreen Plan provides that under no circumstances shall the Evergreen Plan, together with all of the Company's other previously established or proposed stock options, stock option plans, employee stock purchase plans or any other compensation or incentive mechanisms involving the issuance or potential issuance of shares, result, at any time, in the number of shares: (i) issued to insiders, within any one year period, exceeding 10% of the number of shares then outstanding; (ii) issuable to insiders, at any time, exceeding 10% of the number of shares then outstanding; (iii) issued to any one insider and such insider's associates, within any one year period, exceeding 5% of the number of shares then outstanding; and (iv) issuable to any one participant, at any time, exceeding 5% of the number of shares then outstanding.

In the event of the death of an optionee, options held by such optionee may be exercised until the earlier of the expiry date of such options or one year from the date of death, after which the options terminate. In the event that an optionee ceases to be an Eligible Participant for any reason other than for cause or by virtue of death, then options held by such optionee shall remain exercisable for a period of 30 days after the date on which such optionee ceases to be an Eligible Participant or the expiration date of such options, whichever is earlier. Where, however, the employment or service contract with an optionee is terminated for cause, no option held by such optionee shall be exercisable following the date on which such optionee ceases to be an Eligible Participant.

The Evergreen Plan requires Shareholder approval for amendments to the Evergreen Plan (other than those requiring only Board approval as set out below) including the following:

(a) any amendment to the fixed percentage of shares issuable under the Evergreen Plan, including a change from the fixed maximum percentage of 10% of the issued and outstanding shares to a fixed maximum number;
(b) any change to the definition of “Eligible Participant” which would have the potential of broadening or increasing insider participation;
(c) the addition of any form of financial assistance;
(d) the addition of a cashless exercise feature, payable in cash or securities, which does not provide for a full deduction of the number of underlying shares from the Evergreen Plan reserve;
(e) the addition of a deferred or restricted share unit or any other provision which results in Eligible Participants receiving shares while no cash consideration is received by the Company; and

(f) any other amendments that may lead to significant or unreasonable dilution in the Company's outstanding securities or may provide additional benefits to Eligible Participants, especially insiders of the Company, at the expense of the Company and its existing Shareholders.

The Evergreen Plan requires only Board approval for the following types of amendments, as outlined in the Evergreen Plan:

(a) amendments considered to be of a clerical nature;
(b) a change to the vesting provisions of a security or to the Evergreen Plan itself;
(c) a change to the termination provisions of a security or to the Evergreen Plan itself which does not entail an extension beyond the original expiry date;
(d) a change to reduce the exercise price of a security for an Eligible Participant who is not an insider (as defined in the Evergreen Plan);
(e) the addition of a cashless exercise feature, payable in cash or securities, which provides for a full deduction of the number of underlying securities from the Evergreen Plan's reserve; and
(f) amendments of a non-material nature which are approved by the TSX.

On August 26, 2009, the Shareholders approved certain amendments to the Evergreen Plan in order to: adjust the securities that an optionee will receive on exercise after the completion of a compulsory acquisition or other going private transaction following a take-over bid; adjust the expiry date of options received by an optionee in a new company in the event that the Company completes a plan of arrangement or spin-out transaction; clarify existing adjustment provisions with respect to outstanding options on completion of share reorganizations, special distributions and other corporation reorganizations; and update certain legislative and statutory references and correct certain typographical errors and cross referencing errors.

On July 23, 2012, the Board of Directors also made certain non-material amendments to the Evergreen Plan (a) to clarify, and conform to the TSX Company Manual, the wording regarding the insider participation limits in the Evergreen Plan, and (b) to provide that the Company's optionholders who are resident in the United States are required to provide for certain representations and warranties to the Company, in order to ensure compliance by the Company with the provisions of the U.S. Securities Act. These non-material amendments to the Evergreen Plan were ratified by Shareholders on September 6, 2012 and approved by the TSX on September 14, 2012.

The Evergreen Plan requires Shareholder approval every three years. As the Evergreen Plan was implemented by the Company in 2006 and re-approved by the Shareholders in 2009 and 2012, Shareholder approval of the Evergreen Plan is not required at the Company’s Annual General Meeting (the “Meeting”) scheduled for September 12, 2013.

There is a maximum of 16,860,170 common shares reserved for issuance under the Evergreen Plan, representing approximately 7.99% of the issued and outstanding common shares of the Company as at the date of this annual report on Form 20-F.

A total of 12,800,000 options were under grant prior to re-approval of the Evergreen Plan by Shareholders in September 2012. Since then, 3,660,000 new options have been granted, 1,200,000 previously-granted options expired and no options have been exercised. Accordingly, as of the date hereof, 15,260,000 options are currently under grant, representing approximately 7.23% of the issued and outstanding common shares of the Company as of the date of this annual report on Form 20-F.

The Company does not have a pension plan that provides for payments or benefits to the Named Executive Officers at, following, or in connection with retirement.

The Company has a current employment agreement with Thomas Shrake, President and CEO, which includes termination and change of control benefits.

In Mr. Shrake’s employment agreement, “change of control” is defined as any change in the effective control or direction of the Company and includes:

An “event of termination” is defined in the employment agreement as the occurrence of any of the following events at any time after a “change of control”, without the executive’s written consent:

If, as a result of a “change of control” of the Company, Mr. Shrake experiences an “event of termination” as described above, Mr. Shrake is entitled to a severance payment of 24 months’ salary (based on his official annual salary of US$250,000) and is able to exercise any stock options previously granted within 45 business days in the event of termination after a change of control. The estimated incremental value of his non-vested stock options that would vest assuming a triggering event took place on the last day of the most recently completed financial year would have been $Nil as the Company’s closing share price on April 30, 2013 was CDN$0.04, lower than the exercise price of all vested and non-vested stock options granted to Mr. Shrake.

Steven Krause has a consulting agreement with the Company which includes a “change of control” clause. In this consulting agreement, “change of control” means the acquisition by any person or by any person and joint actor, whether directly or indirectly, of voting securities as defined in the Securities Act of British Columbia, as amended from time to time (the “BC Securities Act”), which, when added to all other voting securities of the Company at the time held by such person or by such person and a person acting “jointly or in concert with” another person as that phrase is interpreted by the BC Securities Act, totals for the first time not less than fifty percent (50%) of the outstanding voting securities of the Company or the votes attached to those securities are sufficient, if exercised, to elect a majority of the Board of Directors.

Should a “change of control” occur, all outstanding stock options held by Mr. Krause will become fully vested in accordance with the terms of the Evergreen Plan whereupon such options may be exercised in whole or in part by Mr. Krause. The estimated incremental value of his non-vested stock options that would vest assuming a triggering event took place on the last day of the most recently completed financial year would have been $Nil as the Company’s closing share price on April 30, 2013 was CDN$0.04, lower than the exercise price of all vested and non-vested stock options granted to Mr. Krause.

William Gehlen has an employment agreement with a subsidiary of the Company that includes termination and change of control conditions which are the same as those in Mr. Shrake’s employment agreement described above. If, as a result of a “change of control” of the Company, Mr. Gehlen experiences an “event of termination” as defined above, Mr. Gehlen is entitled to a severance payment of 12 months’ salary, plus one month’s salary per year of service after one year, up to a maximum of 24 months’ salary, and is able to exercise any stock options previously granted within 30 calendar days in the event of termination after a change of control. The estimated incremental value of his non-vested stock options that would vest assuming a triggering event took place on the last day of the most recently completed financial year would have been $Nil as the Company’s closing share price on April 30, 2013 was CDN$0.04, lower than the exercise price of all vested and non-vested stock options granted to Mr. Gehlen.

Other than as set forth above, neither the Company nor its subsidiaries has a contract, agreement, plan or arrangement that provides for payments to a Named Executive Officer following or in connection with any termination (whether voluntary, involuntary or constructive), resignation, retirement, a change of control of the Company or its subsidiaries, or a change in responsibilities of the Named Executive Officer following a change in control.

Under the terms of Thomas Shrake’s employment agreement, the estimated incremental payment to Mr. Shrake upon termination by the Company on a change of control of the Company, would be approximately US$500,000 (calculated as at April 30, 2013) based upon an amount equal to 24 months’ salary, plus any amounts owed in respect of accrued vacation and the accelerated option value of his existing stock options.

There are no provisions in Steven Krause’s consulting agreement that would require the Company to make any payments to Mr. Krause upon a change of control of the Company.

Under the terms of William Gehlen’s employment agreement, the estimated incremental payment to Mr. Gehlen upon termination by the Company’s subsidiary on a change of control of the Company, would be approximately US$240,000 (calculated as at April 30, 2013) based upon an amount equal to 12 months’ salary plus one months’ salary for every year of service beyond one year to a maximum of 24 months’ salary, plus any amounts owed in respect of accrued vacation and the accelerated option value of his existing stock options.

The Company has no arrangements, standard or otherwise, pursuant to which Directors are compensated by the Company or its subsidiaries for their services in their capacity as Directors, or for committee participation, involvement in special assignments, or for services as a consultant or expert during the most recently completed financial year or subsequently, up to and including the date of this report, except as follows:

The Evergreen Plan, as described above, allows for the granting of incentive stock options to the officers, employees and Directors of the Company. The purpose of granting such options is to assist the Company in compensating, attracting, retaining and motivating the Directors of the Company and to closely align the personal interests of such persons to that of the Shareholders.

Details of the Company’s Evergreen Plan are set out above under the heading “Description of Incentive Plan”.

Corporate governance relates to the activities of the Company’s Board of Directors, the members of which are elected by and are accountable to the Shareholders, and takes into account the role of the individual members of management who are appointed by the Board and who are charged with the day-to-day management of the Company. The Board is committed to sound corporate governance practices which are both in the interests of the Shareholders and contribute to effective and efficient decision making.

Canadian National Policy 58-201, Corporate Governance Guidelines, establishes corporate governance guidelines which apply to all public companies. The Company has reviewed its own corporate governance practices in light of these guidelines. In certain cases, the Company’s practices comply with the guidelines; however, the Board considers that some of the guidelines are not suitable for the Company at its current stage of development and level of activity and therefore these guidelines have not been adopted. Canadian National Instrument 58-101, Disclosure of Corporate Governance Practices, mandates disclosure of corporate governance practices, which disclosure is set out below.

The Board currently consists of five Directors, a majority of whom are independent based upon the tests for independence set forth in NI 52-110. Assuming each of the nominated Directors is elected by Shareholders at the Meeting on September 12, 2013, the Board will include three (3) independent Directors: Messrs. Myckatyn, Fagin and Baker. Mr. Shrake and Ms. McLeod-Seltzer are not considered independent as they are the President and Chief Executive Officer, and Board Chairman, respectively, of the Company.

The Board facilitates the exercise of independent judgement in carrying out its responsibilities, by the effective supervision of management by the independent Directors on an informal basis, through active and regular involvement in reviewing and supervising the operations of the Company and through regular and full access to management. Further independent supervision is performed through the Audit Committee which is composed entirely of independent Directors who meet regularly with the Company’s auditors without management being in attendance. The independent Directors hold meetings without the presence of non-independent Directors on a quarterly basis and are also encouraged to meet at any time they consider necessary without any members of management, including the non-independent Directors, being present. The Company’s auditors, legal counsel and certain employees may be invited to attend. During the Company’s most recently completed financial year, the independent Directors met a total of four (4) times.

Leadership is provided for the Board’s independent Directors through access to management and the independent operation of the Audit Committee, as discussed above, and through its Lead Director, Mr. Myckatyn. As Lead Director, Mr. Myckatyn’s role and responsibilities are to:

The following table sets forth directors of the Company that are also a director of any other issuer that is a reporting issuer (or equivalent) in a jurisdiction or foreign jurisdiction.

*Name of Director*	*Name of Other Public Company*
Catherine McLeod-Seltzer	Bear Creek Mining Corporation, Kinross Gold Corporation, Troon Ventures Ltd. and Major Drilling Group International, Inc.
William Myckatyn	First Point Minerals Corp., San Marco Resources Inc., OceanaGold Corporation and Delta Gold Corporation
David K. Fagin	Atna Resources Ltd.
Timothy C. Baker	Augusta Resource Corporation, Antofagasta Plc., Golden Star Resources Ltd.

The Board meets at least once every quarter to review the performance of the Company and address other business matters. The Board also holds a meeting each year to review and assess the Company’s financial forecasts and business plan for the ensuing year and its overall strategic objectives. Other meetings of the Board are called to deal with special matters as circumstances require. During the Company’s most recently completed financial year, five (5) Board meetings were held. The attendance record of each Director for the Board meetings held is as follows:

The mandate of the Board is to manage or supervise the management of the business and affairs of the Company and to act with a view to the best interests of the Company. The Board sets long-term goals and objectives for the Company, formulates the plans and strategies necessary to achieve those objectives and goals, and supervises and offers guidance to the Company’s senior management in their implementation. Although the Board has delegated to senior management personnel the responsibility for managing the day-to-day affairs of the Company, the Board is ultimately responsible for all matters relating to the Company and its business. In fulfilling its mandate, the Board, among other matters, is responsible for reviewing and approving the Company’s overall business strategies and its annual business plan; reviewing and approving the quarterly corporate and cash flow forecasts; reviewing and approving significant capital investments; reviewing major strategic initiatives to ensure that the Company’s proposed actions accord with Shareholder objectives; reviewing succession planning; assessing management’s performance against approved business plans and industry standards; reviewing and approving the reports and other disclosure issued to Shareholders; ensuring the effective operation of the Board; and safeguarding Shareholders’ equity interests through the optimum utilization of the Company’s capital resources.

The Board expects management to efficiently implement its strategic plans for the Company in a professional, competent and ethical manner, to keep the Board fully apprised of its progress in doing so and to be fully accountable to the Board in respect to all matters for which it has been assigned responsibility. In addition to matters which must, by law or pursuant to the constating documents of the Company, be approved by the Board, all matters of strategic importance to the Company are referred to the Board for prior review and approval. Any material expenditures or legal commitments, including without limitation debt or equity financings, acquisitions and divestitures by the Company, financial statements and major disclosure documents, are subject to prior approval by the Board. The Board holds meetings on a regular basis to review the Company’s strategy as well as to consider and approve particular matters. One of the Board’s responsibilities is to review and, if thought fit, to approve opportunities as presented by management and to provide guidance to management. The Board expects management to operate the business of the Company in a manner that enhances Shareholder value and is consistent with the highest level of integrity. Management is expected to execute the Company’s business plan and to meet performance goals and objectives.

The Board oversees the management of the Company’s affairs directly and through its committees. The Board also meets to plan for the future growth of the Company; to identify risks of the Company’s business, thus ensuring the implementation of appropriate systems to manage these risks; to monitor senior management; and to ensure timely disclosure of material transactions. The frequency of Board meetings as well as the nature of agenda items, change, depending upon the state of the Company’s affairs and in light of opportunities or risks that the Company faces. When necessary and appropriate, issues may be approved and adopted by the Board by way of written resolutions in accordance with applicable corporate law.

The Board has developed written position descriptions for the Chairman, the President and CEO and for the Directors at large. On a quarterly basis, the Board approves the operating and capital forecasts, and the Chairman and President and CEO are required to ensure the Company operates within those guidelines. Material departures must be approved by the Board. The Board is of the view that the respective corporate governance roles of the Board and management, as represented by the Chairman and President and CEO, are clear, and that the limits to management’s responsibility and authority are well defined.

The Board has not developed written position descriptions for the Chair of each Board committee. The Chairs of the Audit Committee, the Nominating Committee, the Compensation Committee, and the Health, Safety and Environmental Committee are responsible for calling the meetings of each Committee, establishing meeting agenda with input from management, and supervising the conduct of the meetings.

New Directors are provided with a Board Manual, as reviewed and adopted by the Board, which contains comprehensive information and guidelines on the duties of the Board, and members of management, terms of reference for committees and policies adopted by the Board. New Directors are given a detailed briefing by the Chairman of the Board and by the President and CEO on the Company and its business, and the legal duties and obligations of Directors. The President and CEO reports at each Board meeting on the Company’s activities and provides Directors with a monthly written report. All Directors are encouraged to contact senior management for updates at any time.

The Board currently does not provide continuing education for its Directors. By using a Board composed of experienced professionals with a wide range of financial, legal, exploration and mining expertise, the Company ensures that the Board operates effectively and efficiently.

Board members are encouraged to communicate with management, legal counsel and, where applicable, auditors and technical consultants of the Company; to keep themselves current with industry trends and developments and changes in legislation with management’s assistance; and to attend related industry seminars and visit the Company’s operations. Board members have full access to the Company’s records.

The Board has adopted a written Code of Conduct and Ethics and a Whistleblower Policy by which it and all officers and employees of the Company abide. The Whistleblower Policy outlines a confidential and anonymous process in which to report any accounting concerns while the Code of Conduct helps define and establish a standard of professional behaviour and responsibility, acceptable to the Company, for all employees. A copy of the Code of Conduct and Ethics and the Whistleblower Policy is available for review on the Company’s website and on SEDAR at www.sedar.com. In addition, the Board, through its meetings with management and other informal discussions with management, monitors in compliance with the Code of Conduct and Ethics and encourages a culture of ethical business conduct. The Company’s high calibre management team promotes a culture of ethical business conduct throughout the Company’s operations and is expected to monitor the activities of the Company’s employees, consultants and agents in that regard. The Board encourages any concerns regarding ethical conduct in respect of the Company’s operations to be raised, on an anonymous basis, with the President and CEO, the Chairman, or another Board member as appropriate.

It is a requirement of applicable corporate law that Directors and senior officers who have an interest in a transaction or agreement with the Company promptly disclose that interest at any meeting of the Board at which the transaction or agreement will be discussed and, in the case of Directors, abstain from discussions and voting in respect to same if the interest is material. These requirements are also contained in the Company’s Articles, which are made available to the Directors and senior officers of the Company.

The following is the text of the Audit Committee’s Charter (Amended and Restated effective July 29, 2004):

b) A resolution in writing signed by all members of the Audit Committee entitled to vote on that resolution at a meeting of the Audit Committee shall be as valid as if it had been passed at a duly called and constituted meeting.

g) Subject to the foregoing, the calling, holding and procedure at meetings of the Audit Committee shall be determined by the Audit Committee Chair.

While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine if the Company’s financial statements or disclosures are complete and accurate and are in accordance with GAAP and applicable rules and regulations. These are responsibilities of management and the independent auditors.”

The members of the Audit Committee are David Fagin, William Myckatyn and Tim Baker. All of the members are financially literate and independent for the purposes of Canada’s National Instrument 52-110 (“NI 52-110”) and the standards set forth in the NYSE MKT Company Guide.

Mr. Fagin is a financial expert, in that he has an understanding of International Financial Reporting Standards and financial statements; is able to assess the general application of accounting principles in connection with the accounting for estimates, accruals and reserves; has experience preparing, auditing, analyzing or evaluating financial statements that entail accounting issues of equal complexity to the Company’s financial statements (or actively supervising another person who did so); has an understanding of internal controls and procedures for financial reporting and an understanding of audit committee functions. Mr. Fagin does not have an accounting designation; instead his expertise is derived from his high level involvement in the financial matters of public corporations almost continuously for at least 35 years. Mr. Fagin was involved in the valuation of oil and gas companies for ten years both as a consultant and a bank appraisal engineer (1958-68); President of a subsidiary of Rosario Resources Corporation, a NYSE company (1968-75), Executive Vice-President (1975-77) then President (1977-82) during which period he was intimately involved in financial and accounting matters. In 1982, he founded Fagin Exploration Company and worked closely with an accountant and auditors to maintain the records. From 1986 to 1991, Mr. Fagin was the President and Chief Operating Officer for Homestake Mining Corporation (NYSE), responsible for producing operations in six countries and was involved in decisions for corporate financial reporting. Between 1992 and 1996, Mr. Fagin was Executive Chairman of Golden Star Resources Ltd. (ASE and TSE) and managed all administrative matters including annual reports, audits and registration in Canada and the US. Since 1987, Mr. Fagin has served on boards and audit committees of several public companies including T. Rowe Price Mutual Funds, Golden Star Resources Ltd., Canyon Resources Corp. (acquired by Atna Resources Ltd.), Dayton Mining Corp. and the Company, where he was either Chairman or a member of each audit committee. He currently remains a director of Atna Resources Ltd.

Mr. Myckatyn does not have an accounting designation. However, Mr. Myckatyn is financially literate in that he has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Company’s financial statements. Mr. Myckatyn has over 30 years’ experience in the mining industry. Mr. Myckatyn was the co-founder and CEO of Quadra Mining Ltd. from 2002 to 2006 and was the Chairman, President and Chief Executive Officer of Dayton Mining Corporation from 1998 to April, 2002 during which time he oversaw the restructuring of Dayton and its subsequent merger with the Company. Prior to 1998, Mr. Myckatyn was the President and CEO of Princeton Mining Corporation, overseeing completion in 1997 of the construction of the Huckleberry open-pit copper mine in British Columbia and the 1998 merger of the company with Imperial Metals Corporation. Mr. Myckatyn worked for Gibraltar Mines Limited from 1991 to 1996, initially as Mine Manager and ultimately as President and CEO as the company transitioned from being controlled by Placer Dome Inc. into an independent growth oriented public company, and through its acquisition by Westmin Resources Inc. in 1996. For over ten years prior to that, Mr. Myckatyn worked for various operations controlled by Placer Dome Inc. and its associated and predecessor companies including four separate mines in Australia and the Philippines. Mr. Myckatyn is a director of First Point Minerals Corporation, San Marco Resources Inc., OceanaGold Corporation and Delta Gold Corporation. Mr. Myckatyn received his Bachelor of Applied Science in Mining Engineering from the University of British Columbia in 1972.

The third member of the Company’s audit committee, Tim Baker, is financially literate in that he has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Company’s financial statements. Mr. Baker has worked in a senior executive capacity for several senior mining companies including Placer Dome Inc. and Kinross Gold Corporation. Since his retirement in 2011, Mr. Baker has joined the boards of several other mining companies and is currently the Executive Chairman of Golden Star Resources Ltd.

The Nominating Committee is composed of two Directors, Messrs. Baker (Chair) and Myckatyn, each of whom is independent based upon the tests for independence set forth in NI 52-110 and in the NYSE MKT Company Guide. The Nominating Committee has the responsibility for recommending to the Board the nominees to fill vacancies on the Board or to be proposed by any member of the Board as candidates for election as Directors at the annual general meeting. The Nominating Committee also recommends to the Board a desirable balance of expertise among the Board members, seeks out possible candidates to fill Board positions and aids in attracting qualified candidates to the Board. In addition, the Nominating Committee’s responsibilities include reviewing and monitoring the orientation of new Board members; reviewing and approving officers’ directorships in other companies and reviewing Directors’ relationships with outside entities with regard to potential conflicts of interest.

The Compensation Committee is composed of Messrs. Fagin (Chair) and Myckatyn, each of whom is independent based upon the tests for independence set forth in NI 52-110 and in the NYSE MKT Company Guide. The overall purpose of the Compensation Committee is to make recommendations to the Board for human resources and compensation policies and to implement and oversee same if the Board approves the recommendations for the Company.

The Compensation Committee is responsible for reviewing all overall compensation strategy, objectives and policies; annually reviewing and assessing the performance of the executive officers; recommending to the Board the compensation of the executive officers; reviewing executive appointments; and reviewing the adequacy and form of Directors’ compensation.

To determine compensation payable, the Compensation Committee reviews compensation paid for Directors and officers of companies of a similar size and stage of development in the mineral exploration industry and determines an appropriate compensation reflecting the need to provide incentive and compensation for the time and effort expended by the Directors and senior management, while taking into account the financial and other resources of the Company. The Board of Directors does not benchmark its executive compensation program, but from time to time does review compensation practices of companies of similar size and stage of development to ensure the compensation paid is competitive within the Company's industry and geographic location while taking into account the financial and other resources of the Company. See also “Statement of Executive Compensation” above.

No compensation consultant or advisor has, at any time since the beginning of the Company’s most recently completed financial year, been retained to assist in determining compensation for any of the Company’s Directors or officers.

Committees of the Board are an integral part of the Company’s governance structure. In addition to the Compensation, Nominating and Audit Committees (described above), the Board has a Health, Safety and Environmental Committee. The Board’s committees have been established to devote the necessary expertise and resources to particular areas, and to enhance the quality of discussion at Board meetings. The Committees facilitate effective Board decision making by providing recommendations to the Board on matters within their respective responsibilities. The Board believes that the Committees assist in the effective functioning of the Board and that the composition of the Committees should ensure that the views of the independent Directors are effectively represented.

The Company’s Health, Safety and Environmental Committee is composed of Messrs Myckatyn (Chair), Shrake and Baker, a majority of whom are considered independent based upon the tests for independence set forth in NI 52-110. The Health, Safety and Environmental Committee has the responsibility for reviewing the Company’s environmental policy and for ensuring that the Company’s operations are conducted in a manner consistent with the environmental policy and in a manner that does not unduly expose its employees to unnecessary risk of accident or death.

The Board has determined that, at this stage of the Company’s development, it is not necessary for the Board to have additional standing committees. The Board may from time to time appoint a special committee of one or more Directors which committee may engage an outside advisor at the Company’s expense in order to assist the committee in fulfilling its responsibilities.

The Board annually, and at such other times as it deems appropriate, reviews the performance and effectiveness of the Board, the Directors and its committees to determine whether changes in size, personnel or responsibilities are warranted. To assist in its review, the Board conducts informal surveys of its Directors respecting its own effectiveness. In addition, the Board satisfies itself that the Board, its committees, and its individual Directors are performing effectively through frequent discussions between management and individual Board members. There are also discussions among the independent Directors with resulting comments to the Board. If appropriate, the Board then considers whether procedural or substantive changes are necessary to increase the effectiveness of the Board and its committees.

The Company is dedicated to the maintenance of good Shareholder relations and attempts to deal with any expressed concerns of Shareholders in an effective and timely manner. The Company employs a Vice-President of Investor Relations to monitor and promptly address Shareholder concerns in an expeditious and informal manner. If any material issues of concern arise, the Board of Directors is informed and provides direction for action as needed. The Company has a Disclosure Policy which is followed and is available for review on the Company’s website.

As at April 30, 2013, the Company (including its subsidiaries) had one employee in Canada, five employees in the US and 4 full time plus 24 part-time employees in El Salvador. None of the Company’s employees are represented by labor unions.

Upon closing of the private placement, and as of the date of this annual report on Form 20-F, OceanaGold owned and controlled approximately 19.98% of the Company's issued and outstanding share capital. In connection with the private placement, Oceanagold was granted the right, until October 3, 2014, to participate in future equity financings to maintain its percentage interest in the Company or, subject to regulatory and Shareholder approval, to increase its percentage interest in the Company to 25%. In addition, if Oceanagold elects to sell its shares prior to October 3, 2014, the Company has the right to attempt to find a purchaser for such common shares.

The Company’s post-amalgamation shares were called for trading on the TSX and the American Stock Exchange (now known as the NYSE MKT), on April 15, 2002 under the symbol “PMU”. In September 2010 the Company delisted from NYSE Amex (now known as the NYSE MKT) and the TSX is the only exchange on which the Company’s shares are listed. The Company’s shares additionally trade on the OTCQX platform in the US. Prior to April 15, 2002 Dayton’s shares traded as “DAY” on the TSX and the American Stock Exchange (now known as the NYSE MKT) and the Company’s shares traded as “PFG” on the TSX.

The Company’s common shares are listed and trade on the TSX under the symbol “PMU” and additionally trade on the OTCQX platform under the symbol “PFRMF”. The Company has received advice that its shares are listed and have traded since June 14, 2002 on the Berlin Stock Exchange under the symbol PRM, German Cusip Number 577332 and in the Regulated Unofficial Market (Freiverkehr) on the Frankfurt Stock Exchange on the Xetra, the Deutsche Borse AG electronic trading system since May 31, 2002.

In June 2011, Pacific Rim, through its US subsidiary Pacific Rim Exploration Inc. signed a Definitive Agreement with ICN Resources Ltd. and Washoe Gold Inc. providing the Company with the option to acquire a 65% joint venture interest in the Hog Ranch Property located in Washoe County, Nevada, approximately 180 km north of Reno. ICN (and its interest in the Hog Ranch property) was subsequently acquired by Corazon Gold Corp (“Corazon”)

The Company held the Hog Ranch Property through fiscal 2013 but subsequently, in May 2013, Pacific Rim, on behalf of PREx, informed Corazon of its intent not to proceed further with its option agreement to acquire an interest in the Hog Ranch property. This decision resulted from the Board of Directors determination that the Company was not in a financial position to make the $1.0 million exploration expenditures that were required before the July 2013 deadline as per the terms of the Definitive Agreement. See Item 4D – “Property Plant and Equipment”, specifically “Hog Ranch Property, Nevada” above for further details.

During fiscal 2011, the Company signed an LOI with Compania Minera Clifton S.A. (“Minera Clifton”) (collectively with the Company, the “Remance Parties”) to acquire a 100% interest in the Remance project located in Panama, Central America.

The Remance Parties have agreed to sign a Formal Agreement granting the Company the exclusive right and option to acquire 100% of Minera Clifton's right, title and interest in the Remance project as soon as practicable. Signing of the Formal Agreement has not been concluded at this time and is currently highly uncertain. Minera Clifton’s application for an extension to the Remance concession term, as provided by Panamanian law, was recently denied; a decision which is currently being appealed by Minera Clifton. While the Company is keeping the Remance LOI in effect during Minera Clifton’s appeal, the outcome of this process, and hence the Company’s final acquisition of the Remance project, is highly uncertain. If signed, the Formal Agreement will be subject to all required regulatory approvals, including the approval of the Toronto Stock Exchange (the “TSX”). The option to acquire Remance may be exercised by the Company by paying an aggregate of $200,000 in four equal tranches plus 5 million common shares of Pacific Rim to Minera Clifton, conducting a specified exploration program during the Option Period (as defined in the LOI) and paying $5 million in cash or common shares to Minera Clifton at the end of the Option Period.

As noted above, the Remance project acquisition has not currently been completed and is highly uncertain at this time. The Company believes that Minera Clifton’s application for extension of the Remance concession term, normally a routine process permitted under Panamanian mining law, was sidelined by bureaucratic irregularities and issues within the ministry responsible for mining. If the Remance extension is ultimately granted to Minera Clifton, the Company intends to proceed with its acquisition of the Remance Project by signing the Formal Agreement. See Item 4D – “Property Plant and Equipment”, specifically “Remance Property, Panama” above for further details.

In October 2012 the Company signed a service and fee agreement (the “Final Phase Fee Agreement”) with its legal counsel Crowell & Moring, LLP. The Final Phase Fee Agreement provides the Company with cost certainty in regards to Arbitration-related legal fees as it proceeds through the final phase of the claim. It does not apply to ancillary Arbitration-related expenses such as court costs, expert testimony, translation services, etc., which may be significant. Under the terms of the Final Phase Fee Agreement, Pacific Rim will pay $750,000 of its outstanding liability to Crowell & Moring before the end of calendar 2013. Crowell & Moring has agreed to bill the Company periodically for legal fees, at a discounted rate, incurred through the Final Phase of the Arbitration to a maximum of $1.4 million. The Company has agreed to pay Crowell & Moring a success fee of up to $2.5 million under certain circumstances wherein a favorable outcome to the dispute is reached.

There are currently no governmental laws, decrees, regulations or other legislation of Canada which affect the import or export of capital, including the availability of cash and cash equivalents for use by the Company.

Although not free from doubt, the Company believes it was classified as a "passive foreign investment company" during the tax year ended April 30, 2013, and may be classified as a “passive foreign investment company in future tax years. If the Company is a “passive foreign investment company” for a tax year, such classification will likely have adverse US federal income tax consequences for US shareholders.

US investors in our Common Shares should be aware that the Company believes it was classified as a passive foreign investment company (“PFIC”) during the tax year ended April 30, 2013 and may be classified as a PFIC for future tax years. If the Company is a PFIC for any year during a US shareholder’s holding period, then such US shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any so-called “excess distribution” received on its Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the shareholder makes a timely and effective "qualified electing fund" election (“QEF Election”) or a "mark-to-market" election with respect to the Common Shares. A US shareholder who makes a QEF Election generally must report on a current basis its share of the Company's net capital gain and ordinary earnings for any year in which the Company is a PFIC, whether or not the Company distributes any amounts to its shareholders. However, US shareholders should be aware that there can be no assurance that the Company will satisfy record keeping requirements that apply to a qualified electing fund, or that the Company will supply US shareholders with information that such US shareholders require to report under the QEF rules, in the event that the Company a PFIC and a US shareholder wishes to make a QEF Election. Thus, US shareholders may not be able to make a QEF Election with respect to their Common Shares. A US shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis therein. This paragraph is qualified in its entirety by the discussion below under the heading “Certain United States Federal Income Tax Considerations.” Each US shareholder should consult its own tax advisor regarding the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our Common Shares.

The following is a general summary of certain material US federal income tax considerations applicable to a US Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of Common Shares.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential US federal income tax considerations that may apply to a US Holder arising from and relating to the acquisition, ownership, and disposition of Common Shares. In addition, this summary does not take into account the individual facts and circumstances of any particular US Holder that may affect the US federal income tax consequences to such US Holder, including specific tax consequences to a US Holder under an applicable tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or US federal income tax advice with respect to any US Holder. Each US Holder should consult its own tax advisor regarding the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of Common Shares.

No legal opinion from US legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the US federal income tax consequences of the acquisition, ownership, and disposition of Common Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the US courts could disagree with one or more of the positions taken in this summary.

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, US court decisions, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-US Tax Convention”), and US court decisions that are applicable and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive or prospective basis which could affect the US federal income tax considerations described in this summary. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

For purposes of this summary, the term "US Holder" means a beneficial owner of Common Shares that is for US federal income tax purposes:

For purposes of this summary, a “non-US Holder” is a beneficial owner of Common Shares that is not a US Holder. This summary does not address the US federal income tax consequences to non-US Holders arising from and relating to the acquisition, ownership, and disposition of Common Shares. Accordingly, a non-US Holder should consult its own tax advisor regarding the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences (including the potential application of and operation of any income tax treaties) relating to the acquisition, ownership, and disposition of Common Shares.

This summary does not address the US federal income tax considerations applicable to US Holders that are subject to special provisions under the Code, including the following US Holders: (a) US Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) US Holders that are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) US Holders that are dealers in securities or currencies or US Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) US Holders that have a “functional currency” other than the US dollar; (e) US Holders that own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) US Holders that acquired Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) US Holders that hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) partnerships and other pass-through entities (and investors in such partnerships and entities); or (i) US Holders that own or have owned (directly, indirectly, or by attribution) 10% or more of the total combined voting power of the outstanding shares of the Company. This summary also does not address the US federal income tax considerations applicable to US Holders who are (a) US expatriates or former long-term residents of the US, (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Income Tax Act (Canada) (the “Tax Act”); (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Common Shares in connection with carrying on a business in Canada; (d) persons whose Common Shares constitute “taxable Canadian property” under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-US Tax Convention. US Holders that are subject to special provisions under the Code, including US Holders described immediately above, should consult their own tax advisor regarding the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of Common Shares.

If an entity that is classified as a partnership (or “pass-through” entity) for US federal income tax purposes holds Common Shares, the US federal income tax consequences to such partnership and the partners of such partnership generally will depend on the activities of the partnership and the status of such partners. This summary does not address the tax consequences to any such partner. Partners of entities that are classified as partnerships for US federal income tax purposes should consult their own tax advisor regarding the US federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Common Shares.

This summary does not address the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences to US Holders of the acquisition, ownership, and disposition of Common Shares. Each US Holder should consult its own tax advisor regarding the US federal, US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences of the acquisition, ownership, and disposition of Common Shares.

If the Company were to constitute a “passive foreign investment company” under the meaning of Section 1297 of the Code (a “PFIC”, as defined below) for any year during a US Holder’s holding period, then certain different and potentially adverse rules will affect the US federal income tax consequences to a US Holder resulting from the acquisition, ownership and disposition of Common Shares.

Recently enacted U.S. legislation requires each U.S. person who directly or indirectly owns an interest in a PFIC to file an annual report with the IRS, and failure to file such report could result in the imposition of penalties on such U.S. person and in the extension of the statute of limitations with respect to federal income tax returns filed by such U.S. person. However, this reporting requirement has been temporarily suspended. Filings will eventually be required with respect to any year in which the requirement was suspended.

The PFIC rules are complex, and each U.S. Holder should consult an independent tax adviser regarding the PFIC rules, including the potential effect of this legislation on such U.S. Holder’s filing requirements and the advisability of making a QEF election or, if applicable, a mark-to-market election, with respect to each PFIC.

The Company generally will be a PFIC if, for a tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income (the “income test”) or (b) 50% or more of the value of the Company’s assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the “asset test”). “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and form incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all (85% or more) of a foreign corporation’s commodities are stock in trade of such foreign corporation or other property of a kind which would properly be included in inventory of such foreign corporation, or property held by such foreign corporation primarily for sale to customers in the ordinary course of business and certain other requirements are satisfied.

For purposes of the PFIC income test and asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the Company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, “passive income” does not include any interest, dividends, rents, or royalties that are received or accrued by the Company from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.

In addition, under certain attribution rules, if the Company is a PFIC, US Holders will be deemed to own their proportionate share of any subsidiary of the Company which is also a PFIC (a ‘‘Subsidiary PFIC’’), and will be subject to US federal income tax on their proportionate share of (a) a distribution on the shares of a Subsidiary PFIC and (b) a disposition or deemed disposition of shares of a Subsidiary PFIC, both as if such US Holders directly held the shares of such Subsidiary PFIC.

The Company believes that it was classified as a PFIC during the tax year ended April 30, 2013 and may be classified as a PFIC for current and future tax years. The determination of whether any corporation was, or will be, a PFIC for a tax year depends, in part, on the application of complex US federal income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any tax year depends on the assets and income of such corporation over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Company (or a Subsidiary PFIC) concerning its PFIC status or that the Company (and each Subsidiary PFIC) was not, or will not be, a PFIC for any tax year. Each US Holder should consult its own tax advisor regarding the PFIC status of the Company and each Subsidiary PFIC.

If the Company is a PFIC, the US federal income tax consequences to a US Holder of the acquisition, ownership, and disposition of Common Shares will depend on whether such US Holder makes an election to treat the Company and any Subsidiary PFICs as a “qualified electing fund” or “QEF” under Section 1295 of the Code (a “QEF Election”) or a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”). A US Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a “Non-Electing US Holder.”

A Non-Electing US Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of Common Shares and (b) any excess distribution received on the Common Shares. A distribution generally will be an “excess distribution” to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a US Holder’s holding period for the Common Shares, if shorter).

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares, and any “excess distribution” received on Common Shares, must be ratably allocated to each day in a Non-Electing US Holder’s holding period for the respective Common Shares. The amount of any such gain or excess distribution allocated to the tax year of disposition or distribution of the excess distribution and to years before the entity became a PFIC, if any, would be taxed as ordinary income. The amounts allocated to any other tax year would be subject to US federal income tax at the highest tax applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing US Holder that is not a corporation must treat any such interest paid as “personal interest,” which is not deductible.

If the Company is a PFIC for any tax year during which a Non-Electing US Holder holds Common Shares, the Company will continue to be treated as a PFIC with respect to such Non-Electing US Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent tax years. A Non-Electing US Holder may terminate this deemed PFIC status by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Common Shares were sold on the last day of the last tax year for which the Company was a PFIC.

A US Holder that makes a QEF Election for the first tax year in which its holding period of its Common Shares begins, generally, will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Common Shares. However, a US. Holder that makes a QEF Election will be subject to US federal income tax on such US Holder’s pro rata share of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such US Holder, and (b) the ordinary earnings of the Company, which will be taxed as ordinary income to such US Holder. Generally, “net capital gain” is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and “ordinary earnings” are the excess of (a) “earnings and profits” over (b) net capital gain. A US Holder that makes a QEF Election will be subject to US federal income tax on such amounts for each tax year in which the Company is a PFIC, regardless of whether such amounts are actually distributed to such US Holder by the Company. However, for any tax year in which the Company is a PFIC and has no net income or gain, US Holders that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a US Holder that made a QEF Election has an income inclusion, such a US Holder may, subject to certain limitations, elect to defer payment of current US federal income tax on such amounts, subject to an interest charge. If such US Holder is not a corporation, any such interest paid will be treated as “personal interest,” which is not deductible.

A US Holder that makes a QEF Election generally (a) may receive a tax-free distribution from the Company to the extent that such distribution represents “earnings and profits” of the Company that were previously included in income by the US Holder because of such QEF Election and (b) will adjust such US Holder’s tax basis in the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a US Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Common Shares.

The procedure for making a QEF Election, and the US federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as “timely” if such QEF Election is made for the first year in the US Holder’s holding period for the Common Shares in which the Company was a PFIC. A US Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such US Holder files a US federal income tax return for such year.

A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a US Holder makes a QEF Election and, in a subsequent tax year, the Company ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which the Company is not a PFIC. Accordingly, if the Company becomes a PFIC in another subsequent tax year, the QEF Election will be effective and the US Holder will be subject to the QEF rules described above during any subsequent tax year in which the Company qualifies as a PFIC.

US Holders should be aware that there can be no assurances that the Company will satisfy the record keeping requirements that apply to a QEF, or that the Company will supply US Holders with information that such US Holders require to report under the QEF rules, in the event that the Company is a PFIC and a US Holder wishes to make a QEF Election. Thus, US Holders may not be able to make a QEF Election with respect to their Common Shares. Each US Holder should consult its own tax advisor regarding the availability of, and procedure for making, a QEF Election.

A US Holder may make a Mark-to-Market Election only if the Common Shares are marketable stock. The Common Shares generally will be “marketable stock” if the Common Shares are regularly traded on (a) a national securities exchange that is registered with the Securities and Exchange Commission, (b) the national market system established pursuant to section 11A of the Exchange Act, or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange ensure active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter.

A US Holder that makes a Mark-to-Market Election with respect to its Common Shares generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to such Common Shares. However, if a US Holder does not make a Mark-to-Market Election beginning in the first tax year of such US Holder’s holding period for the Common Shares or such US Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares.

A US Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which the Company is a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common Shares, as of the close of such tax year over (b) such US Holder’s tax basis in such Common Shares. A US Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (a) such US Holder’s adjusted tax basis in the Common Shares, over (b) the fair market value of such Common Shares (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

A US Holder that makes a Mark-to-Market Election generally also will adjust such US Holder’s tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of Common Shares, a US Holder that makes a Mark-to-Market Election will recognize ordinary income or ordinary loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years).

A Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the Common Shares cease to be “marketable stock” or the IRS consents to revocation of such election. Each US Holder should consult its own tax advisor regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a US Holder may be eligible to make a Mark-to-Market Election with respect to the Common Shares, no such election may be made with respect to the stock of any Subsidiary PFIC that a US Holder is treated as owning, because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge described above with respect to deemed dispositions of Subsidiary PFIC stock or distributions from a Subsidiary PFIC.

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a US Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Common Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations). However, the specific US federal income tax consequences to a US Holder may vary based on the manner in which Common Shares are transferred.

Certain additional adverse rules will apply with respect to a US Holder if the Company is a PFIC, regardless of whether such US Holder makes a QEF Election. For example under Section 1298(b)(6) of the Code, a US Holder that uses Common Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Common Shares.

Special rules also apply to the amount of foreign tax credit that a US Holder may claim on a distribution from a PFIC. Subject to such special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. The rules relating to distributions by a PFIC and their eligibility for the foreign tax credit are complicated, and a US Holder should consult with their own tax advisor regarding the availability of the foreign tax credit with respect to distributions by a PFIC.

The PFIC rules are complex, and each US Holder should consult its own tax advisor regarding the PFIC rules and how the PFIC rules may affect the US federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.

US Federal Income Tax Consequences of the Acquisition, Ownership, and Disposition of Common Shares

The following discussion is subject to the rules described above under the heading “Passive Foreign Investment Company Rules.”

Subject to the PFIC rules discussed above, a US Holder that receives a distribution, including a constructive distribution, with respect to a Common Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the Company, as computed for US federal income tax purposes. A dividend generally will be taxed to a US Holder at ordinary income tax rates. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a US Holder's tax basis in the Common Shares and thereafter as gain from the sale or exchange of such Common Shares. (See “ Sale or Other Taxable Disposition of Common Shares” below). However, the Company may not maintain the calculations of earnings and profits in accordance with US federal income tax principles, and each US Holder should therefore assume that any distribution by the Company with respect to the Common Shares will constitute ordinary dividend income. Dividends received on Common Shares generally will not be eligible for the “dividends received deduction”. In addition, the Company does not anticipate that its distributions will be eligible for the preferential tax rates applicable to long-term capital gains. The dividend rules are complex, and each US Holder should consult its own tax advisor regarding the application of such rules.

Subject to the PFIC rules discussed above, upon the sale or other taxable disposition of Common Shares, a US Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash plus the fair market value of any property received and such US Holder's tax basis in such Common Shares sold or otherwise disposed of. Subject to the PFIC rules discussed above, gain or loss recognized on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the Common Shares have been held for more than one year.

Gain or loss recognized by a US Holder on the sale or other taxable disposition of Common Shares generally will be treated as “US source” for purposes of applying the US foreign tax credit rules unless the gain is subject to tax in Canada and is resourced as “foreign source” under the Canada-US Tax Convention and such US Holder elects to treat such gain or loss as “foreign source.”

Preferential tax rates apply to long-term capital gain of a US Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gain of a US Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Newly enacted legislation requires certain US Holders who are individuals, estates or trusts to pay up to an additional 3.8% tax on, among other things, dividends and capital gains for tax years beginning after December 31, 2012. US Holders should consult their tax advisors regarding the effect, if any, of this tax on their ownership and disposition of Common Shares.

The amount of any distribution paid to a US Holder in foreign currency, or on the sale, exchange or other taxable disposition of Common Shares, generally will be equal to the US dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into US dollars at that time). If the foreign currency received is not converted into US dollars on the date of receipt, a US Holder will have a basis in the foreign currency equal to its US dollar value on the date of receipt. Any US Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be US source income or loss for foreign tax credit purposes. Each US Holder should consult its own US tax advisor regarding the US federal income tax consequences of receiving, owning, and disposing of foreign currency.

Subject to the PFIC rules discussed above, a US Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Common Shares generally will be entitled, at the election of such US Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a US Holder’s US federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a US Holder’s income subject to US federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a US Holder during a year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a US Holder’s US federal income tax liability that such US Holder’s “foreign source” taxable income bears to such US Holder’s worldwide taxable income. In applying this limitation, a US Holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source” or “US source.” Generally, dividends paid by a foreign corporation should be treated as foreign source for this purpose, and gains recognized on the sale of stock of a foreign corporation by a US Holder should be treated as US source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to the Common Shares that is treated as a “dividend” may be lower for US federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a US Holder. In addition, this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and each US Holder should consult its own US tax advisor regarding the foreign tax credit rules.

Under US federal income tax law and Treasury regulations, certain categories of US Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, US return disclosure obligations (and related penalties) are imposed on US Holders that hold certain specified foreign financial assets in excess of $50,000. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-US person, any financial instrument or contract held for investment that has an issuer or counterparty other than a US person and any interest in a foreign entity. US Holders may be subject to these reporting requirements unless their Common Shares are held in an account at a domestic financial institution. Penalties for failure to file certain of these information returns are substantial. US Holders should consult with their own tax advisors regarding the requirements of filing information returns.

Payments made within the US or by a US payor or US middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Common Shares generally may be subject to information reporting and backup withholding tax, at the rate of 28% (and increasing to 31% for payments made after December 31, 2012), if a US Holder (a) fails to furnish such US Holder’s correct US taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect US taxpayer identification number, (c) is notified by the IRS that such US Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such US Holder has furnished its correct US taxpayer identification number and that the IRS has not notified such US Holder that it is subject to backup withholding tax. However, certain exempt persons, such as corporations, generally are excluded from these information reporting and backup withholding rules. Any amounts withheld under the US backup withholding tax rules will be allowed as a credit against a US Holder’s US federal income tax liability, if any, or will be refunded, if such US Holder furnishes required information to the IRS in a timely manner. Each US Holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

Canada

The Company holds its cash and cash equivalents primarily in US dollar and Canadian dollar denominated accounts and its expenses are primarily incurred in US dollars. At April 30, 2013 the amount of cash held was $914 thousand, the amount of short term investments was $495 thousand, the amount of accounts receivable was $104 thousand and the amount of accounts payable and accrued liabilities was $1,779 thousand. Based on these net exposures at April 30, 2013, the impact of a 10% depreciation or appreciation of the US dollar against the Canadian dollar would result in an increase or decrease of $0.07 million in the Company’s net earnings.

The following table summarizes the remaining contractual maturities of the Company’s financial liabilities and operating and capital commitments at April 30, 2013:

Under the terms of the Final Phase Fee Agreement described in Item 4 D “Property Plan and Equipment” – El Dorado Property, El Salvador, Pacific Rim has agreed to pay its Arbitration legal counsel a success fee of up to $2.5 million under certain circumstances wherein a favorable outcome to the dispute is reached, which represents a contingent contractual obligation of the Company.

The exposure of the Company’s financial instruments to interest risk continues to be limited. B. Qualitative Information about Market Risk The Company’s objectives when managing capital and risk are:

The Company continuously assesses its capital structure in light of economic conditions, debt and equity markets and changes in the Company’s short-term and long-term plans. The Company is not subject to externally imposed capital requirements.

The primary financial instruments currently affecting the Company’s financial condition and results of operations are cash and cash equivalents, receivables, deposits and prepaids. The following describes the types of risk associated with these instruments and the way in which such exposure is managed.

Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the relative reliability of the inputs used to estimate the fair values. The three levels of the fair value hierarchy are:

Level 1 – Unadjusted quoted prices in active markets for identical assets and liabilities
Level 2 – Inputs other than quoted prices that are directly or indirectly observable for the asset or liability; and
Level 3 – Inputs that are not based on observable market data.

The carrying values of receivables, and accounts payable and accrued liabilities approximate their fair value because of the short-term nature of these instruments. The derivative warrant liabilities are recognized at fair value each reporting period and are considered level 3 financial instruments.

Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities that are settled by delivering cash or another financial asset.

The Company does not presently have sufficient working capital to meet its accounts payable and accrued liabilities in addition to its anticipated general and administrative or exploration expenses, or the estimated costs of pursuing the Arbitration action during fiscal 2014 (although the service and fee agreement provides certainty as to legal expenses, additional expenses related to the Arbitration including but not limited to costs related to expert witness testimony, will be incurred and additional unforeseen costs may arise). The Company will require financing during fiscal 2014 to meet these expenses and obligations.

The Company seeks to manage liquidity by maintaining adequate cash and cash equivalent balances to meet its short term commitments and by raising equity or debt financing as required to meet long term commitments The Company has no assurance that such financing will be available or be available on favourable terms. Factors that could affect the availability of financing include fluctuations in the Company’s share price, the state of international debt and equity markets, investor perceptions and expectations, global financial and metals markets, progress on any of the Company’s exploration properties, and developments, if any, on the El Dorado project permitting application.

Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. The Company’s exposure to credit risk is primarily attributable to its liquid financial assets and the maximum credit risk the Company is exposed to is 100% of cash and receivables. The Company limits its exposure to credit risk by depositing its cash and cash equivalents with major international financial institutions. The Company does not have financial assets that are invested in asset backed commercial paper.

The Company’s exposure to foreign currency risk is primarily related to Canadian dollar-denominated transactions. The Company does not enter into foreign exchange contracts to manage this exposure. At April 30, 2013 the impact of a 10% depreciation or appreciation of the US dollar against the Canadian dollar would result in an increase or decrease of $0.07 million in the Company’s net earnings. The Company has not entered into any derivative contracts to manage foreign exchange risk at this time.

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The risk that the Company will realize a loss as a result of a decline in the fair value of the investments included in cash and cash equivalents is limited because these investments are generally held to maturity. Based on the amount of cash and cash equivalents invested as at April 30, 2013 and assuming that all other variables remain constant, a 0.5% change in the applicable interest rate would not be significant.

ITEM 14 MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

As disclosed on June 7, 2013, the Board of Directors has adopted a majority voting policy (the "Majority Voting Policy") for the election of directors of the Company at uncontested meetings, the purpose of which is to bring the Company's policies in line with recent amendments to the TSX Company Manual. Shareholders will continue to vote for, or withhold from voting for, each director nominee separately. The Majority Voting Policy provides that, if a director nominee has a greater number of votes "withheld" from his or her election than votes that are voted in favour of such nominee, the nominee shall promptly submit his or her offer of resignation to the Chairman of the Board of Directors for consideration by the Nominating Committee of the Board. The Majority Voting Policy only applies to uncontested elections, meaning elections where the number of nominees for election is equal to the number of directors to be elected as set out in the management proxy circular for the particular meeting.

Promptly following receipt of an offer of resignation arising from the foregoing circumstances, the Nominating Committee will meet to review the matter and make a recommendation to the Board of Directors. The Nominating Committee of the Board of Directors will consider all factors deemed relevant by its members, including, without limitation, the stated reasons why shareholders who cast "withhold" votes for the director did so, the length of service and qualifications of the director, the director's contributions to the Company and the effect that such resignation may have on the Company, including on the Company's ability to comply with applicable governance rules and policies. The director who submitted his or her offer of resignation shall not participate in any Board or Nominating Committee deliberations on whether to accept the resignation. The decision of the Board of Directors regarding whether to accept or reject a resignation offer will be disclosed to the public.

Shareholders should note that, as a result of the Majority Voting Policy, withholding a vote in respect of a director nominee is effectively the same as a vote against a director nominee in an uncontested election.

A copy of the Company's Majority Voting Policy is filed as Exhibit 1.2 and incorporated by reference in this Annual Report on Form 20-F.

On June 7, 2013, the Board adopted an advance notice policy (the “Advance Notice Policy”) for the purpose of providing Shareholders, Directors and management of the Company with a clear framework for nominating directors of the Company in connection with any annual or special meeting of Shareholders.

The purpose of the Advance Notice Policy is to (i) ensure that all Shareholders receive adequate notice of director nominations and sufficient time and information with respect to all nominees to make appropriate deliberations and register an informed vote; and (ii) facilitate an orderly and efficient process for annual or, where the need arises, special meetings of Shareholders. The Advance Notice Policy fixes the deadlines by which Shareholders must submit director nominations to the Company prior to any annual or special meeting of Shareholders and sets forth the information that a Shareholder must include in a written notice to the Company for any director nominee to be eligible for election at such annual or special meeting of Shareholders.

A copy of the Company's Advance Notice Policy is filed as Exhibit 1.2 and incorporated by reference in this Annual Report on Form 20-F. In order to remain effective following the Meeting, the Advance Notice Policy must be ratified, confirmed and approved by the Shareholders at the Meeting.

The following is a brief summary of certain provisions of the Advance Notice Policy and is qualified in its entirety by the full text of the Advance Notice Policy.

For the purposes of the Advance Notice Policy, "public announcement" means disclosure in a press release reported by a national news service in Canada, or in a document publicly filed by the Company under its profile on SEDAR at www.sedar.com.

The Board may, in its sole discretion, waive any provision or requirement of the Advance Notice Policy.

If approved at the Meeting, the Advance Notice Policy will continue to be effective in accordance with its terms. The Advance Notice Policy will be subject to annual review by the Board, and will be updated from time to time to reflect changes required by securities regulatory agencies or stock exchange, or to conform to industry standards, as determined by the Board.

If not approved at the Meeting, the Advance Notice Policy will terminate and be of no further force and effect from and after the termination of the Meeting.

At the Annual General & Special Meeting (“AGSM”) of the Company held on September 6, 2012, shareholders of the Company approved a shareholder rights plan (the “Shareholder Rights Plan”), which became effective immediately after the close of the AGSM, at which time the Company’s existing shareholder rights plan (previously approved by shareholders on August 26, 2009) concurrently expired.

The terms of the Shareholder Rights Plan are set out in an agreement (the "Rights Plan Agreement") between the Company and Computershare Investor Services Inc. A copy of the Company's Shareholder Rights Plan is filed as Exhibit XX and incorporated by reference in this Annual Report on Form 20-F

The Company's management, with the participation of the Chief Executive Officer and Chief Financial Officer, conducted an evaluation, pursuant to Rule 13a-15 promulgated under the Securities Act of 1934, as amended (the "Exchange Act"), of the effectiveness of its disclosure controls and procedures as of April 30, 2013. Based on this evaluation, and as a result of the material weakness in the Company’s internal control over financial reporting discussed below under “Management’s annual report on internal control over financial reporting”, the Chief Executive Officer and Chief Financial Officer also concluded that the disclosure controls and procedures were not effective as of April 30, 2013.

Disclosure controls and procedures means controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms and that such information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures.

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act.

A Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 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 (iii) 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. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

The Company’s management, including the CEO and CFO, have evaluated the effectiveness of the Company’s internal control over financial reporting as at April 30, 2013. This evaluation was based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on that assessment, management concluded that the Company’s internal control over financial reporting was not effective as of April 30, 2013.

A material weakness is a deficiency (as defined in PCAOB Auditing Standard No. 5), or a combination of deficiencies, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

As of April 30, 2013, the Company identified the following material weakness that applies to both disclosure controls and procedures and internal controls over financial reporting:

The company does not maintain adequate segregation of duties necessary to ensure complete and accurate financial reporting. Specifically, the Company’s Chief Financial Officer is responsible for preparing, authorizing, and reviewing information that is integral to the preparation of financial reports. He is also responsible for preparing and reviewing the resulting financial reports. The weakness has the potential to result in material misstatements in the Company’s consolidated financial statements that would not be prevented or detected, and as such has been determined to be a material weakness in internal controls over financial reporting which also impacts the company’s disclosure controls and procedures.

As of the date of this report, management has not yet developed a plan to remediate the material weakness. Management has concluded that taking into account the present stage of the Company’s development the Company does not have sufficient size and scale to warrant hiring of additional staff that would be required to correct the weakness at this time.

This annual report on Form 20-F does not include an attestation report of the Company’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which permits the Company to provide only management’s report in this annual report. The Dodd-Frank Act permits a “non-accelerated filer” to provide only management’s report on internal control over financial reporting in an annual report and omit an attestation report of the Company’s independent registered public accounting firm regarding management’s report on internal control over financial reporting.

During the period covered by this annual report on Form 20-F, there has been no change to the Company’s internal controls over financial reporting that has materially affected, or is reasonably likely to materially affect, its internal control over financing reporting.

David Fagin is a financial expert, in that he has an understanding of International Financial Reporting Standards and financial statements; is able to assess the general application of accounting principles in connection with the accounting for estimates, accruals and reserves; has experience preparing, auditing, analyzing and evaluating financial statements that entail accounting issues of equal complexity to the Company’s financial statements (or actively supervising another person who did so); has an understanding of internal controls and procedures for financial reporting and an understanding of audit committee functions.

Mr. Fagin does not have an accounting designation; instead his expertise is derived from his high level involvement in the financial matters of public corporations almost continuously for at least 35 years. Mr. Fagin was involved in the valuation of oil and gas companies for ten years both as a consultant and a bank appraisal engineer (1958-68); President of a subsidiary of Rosario Resources Corporation, a NYSE company (1968-75) and then Executive Vice-President (1975-77) then President (1977-82) during which period he was intimately involved in financial and accounting matters. In 1982, he founded Fagin Exploration Company and worked closely with an accountant and auditors to maintain the records. From 1986 to 1991, Mr. Fagin was the President and Chief Operating Officer for Homestake Mining Corporation (NYSE), responsible for producing operations in six countries and was involved in decisions for corporate financial reporting. Between 1992 and 1996, Mr. Fagin was Executive Chairman of Golden Star Resources Ltd. (ASE and TSE) and managed all administrative matters including annual reports, audits and registration in Canada and the US. Since 1987, Mr. Fagin has served on boards and audit committees of several public companies including T. Rowe Price Mutual Funds, Golden Star Resources Ltd., Canyon Resources Corp. (recently acquired by Atna Resources Ltd.), Dayton Mining Corp. and the Company, where he was either Chairman or a member of each audit committee. He currently remains a director of Atna Resources Ltd.

Mr. Fagin is considered an independent director according to Canadian securities regulations (Multilateral Instrument 52-110), Toronto Stock Exchange guidelines and the NYSE MKT Company Guide.

The Company has had in place, since 2002, a Code of Conduct and Ethics (the “Code”) that applies to all Directors, officers and employees. A revised Code was approved by the Board of Directors of the Company on December 17, 2002. A copy of the Code can be found on the Company’s website at http://www.pacrim-mining.com/s/CorporateGovernance.asp .

There have never been any departures or material waivers of the Code since its inception.

PricewaterhouseCoopers LLP acted at the Company’s independent auditor for the fiscal years ended April 30, 2011, 2012 and 2013. The chart below sets forth the total amount billed to the Company by PricewaterhouseCoopers LLP for services performed in the last two fiscal years and breaks down these amounts by category of service (for audit fees, audit-related fees, tax fees and all other fees) in Canadian dollars.

The Audit Committee nominates and engages the independent auditors to audit the financial statements, and approves all audit, audit-related services, tax services and other services provided by independent auditors. Any services provided by the independent auditors that are not specifically included within the scope of the audit must be pre-approved by the Audit Committee prior to any engagement.

The Audit Committee is permitted to approve certain fees for audit-related services, tax services and other services pursuant to a de minimus exception before the completion of the engagement.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS

Pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), issuers that are operators (or that have operations), or that have a subsidiary that is an operator (or that has operations), of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities. During the fiscal year ended April 30, 2013, the Company had no such specified health and safety violations, orders or citations, related assessments or legal actions, mining-related fatalities, or similar events in relation to the Company’s United States operations requiring disclosure pursuant to Section 1503(a) of the Dodd-Frank Act.

The financial statements and schedules are commence on page F1 of this annual report and are incorporated herein by reference.

We have audited the accompanying consolidated financial statements of Pacific Rim Mining Corp. which comprise the consolidated statements of financial position as at April 30, 2013 and April 30, 2012 and the consolidated statements of loss and comprehensive loss, shareholders’ equity and cash flows for each of the years in the three year period ended April 30, 2013, and the related notes, which comprise 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 International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is 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 the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement. Canadian generally accepted auditing standards also 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. We were not engaged to perform an audit of the company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company’s internal control over financial reporting. Accordingly, we express no such opinion. 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 audit opinion.

Opinion
In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Pacific Rim Mining Corp. as at April 30, 2013 and April 30, 2012 and its financial performance and its cash flows for each of the years in the three year period ended April 30, 2013 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Emphasis of matter
Without qualifying our opinion, we draw attention to Note 1 in the consolidated financial statements which discloses conditions and matters that indicate the existence of a material uncertainty that raises substantial doubt about Pacific Rim Mining Corp.’s ability to continue as a going concern.

- The accompanying notes are an integral part of these consolidated financial statements -

Pacific Rim Mining Corporation (“Pacific Rim” or the “Company”) is involved in the exploration and development of gold properties. The Company is a public company with shares listed on the TSX Exchange and the PFRMF on OTCQX. The head office, principal address and records office of the Company are located at 625 Howe Street, Suite 1050, Vancouver, British Columbia, Canada, V6C 2T6.

The Company owns a 100% interest in the mineral property known as El Dorado and certain other exploration licenses located in El Salvador and carries out other exploration activities in the United States and Central America.

The Company has not yet determined whether any of its exploration properties contain mineral deposits that are economically recoverable. The recoverability of any amounts capitalized for Mining Property Acquisition costs in El Salvador is dependent upon the existence of economically recoverable mineral deposits, the ability of the Company to obtain the necessary financing and permitting to complete the exploration and development of its exploration properties, and upon future profitable production or proceeds from the disposition of its properties.

While these consolidated financial statements have been prepared on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its commitments, continue operations, realize its assets and discharge its liabilities in the normal course of business for the foreseeable future, there are events and conditions that raise substantial doubt on the validity of that assumption. During the year ended April 30, 2013, the Company had a loss of $4,680 and as at April 30, 2013 had an accumulated deficit of $94,495 and a working capital deficiency of $465. The Company will require additional funding to maintain its ongoing exploration programs and property commitments, for administrative purposes and for the arbitration and legal costs related to the case under the El Salvador’s Foreign Investment Law (“Investment Law”) between the Company and the Government of El Salvador, which is being administered by the Centre for Settlement of Investment Disputes (“ICSID”). The legal and arbitration costs for the case are substantial (Note 9(a)).

While the Company has been successful in obtaining funding in the past, there is no assurance that sufficient funds will be available on favourable terms to the Company in the future. Factors that could affect the availability of financing include the progress and results of the El Dorado project and its permitting application, the resolution of international arbitration proceedings over the non-issuance of permits in El Salvador, the state of international debt and equity markets, investor perceptions and expectations and the global financial and metals markets. The Company anticipates that it will require additional financing through, but not limited to, the issuance of additional equity in order to fund its ongoing exploration and case costs. There can be no assurance the Company will be successful in this endeavour.

These consolidated financial statements do not reflect adjustments in the carrying values of the assets and liabilities, the reported revenues and expenses, and the balance sheet classifications used, that would be necessary if the company were unable to realize its assets and settle its liabilities in the normal course of operations. Such adjustments could be material.

Financial assets and liabilities are recognized when the Company becomes a party to the contractual provisions of the instrument. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the company has transferred substantially all risks and rewards of ownership. Financial liabilities are derecognized when the obligation specified in the contract is discharged, cancelled or expires.

At initial recognition, the Company classifies its financial instruments in the following categories depending on the purpose for which the instruments were acquired:

Equipment and leasehold improvements are stated at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of the asset. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. The carrying amount of a replaced asset is derecognized when replaced. Repairs and maintenance costs are charged to the statement of loss during the period they are incurred.

The major categories of equipment and leasehold improvements are depreciated on a straight-line basis as follows:

The Company allocates the amount initially recognized to each asset’s significant components and depreciates each component separately. Residual values, amortization methods and useful lives of the assets are reviewed periodically and adjusted on a prospective basis as required.

Gains and losses on disposals of equipment are determined by comparing the proceeds with the carrying amount of the asset and are included as part of other gains and losses in the statement of loss.

The carrying amounts of non-financial assets are reviewed for impairment whenever facts and circumstances suggest that the carrying amounts may not be recoverable. If there are indicators of impairment, the recoverable amount of the asset is estimated in order to determine the extent of any impairment. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units or CGUs). The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use (being the present value of the expected future cash flows of the relevant asset or CGU). An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount.

(i) Decommissioning and restoration provision: Future obligations to retire an asset, including dismantling, remediation and ongoing treatment and monitoring of the site related to normal operations are initially recognized and recorded as a liability based on estimated future cash flows discounted at a risk free rate. The decommissioning and restoration provision is adjusted at each reporting period for changes to factors including the expected amount of cash flows required to discharge the liability, the timing of such cash flows and the pre-tax discount rate which reflects the risks specific to the liability.

The liability is also accreted to full value over time through periodic charges to earnings. This unwinding of the discount is charged to financing expense in the statement of income.

The amount of the decommissioning and restoration provision initially recognized is capitalized as part of the related asset’s carrying value and amortized to earnings. The method of amortization follows that of the underlying asset. The costs related to a decommissioning and restoration provision are only capitalized to the extent that the amount meets the definition of an asset and can bring about future economic benefit.

(ii) Other provisions: Provisions are recognized when a current legal or constructive obligation exists, as a result of past events, and it is probable that an outflow of resources that can be reliably estimated will be required to settle the obligation. Where the effect is material, the provision is discounted using an appropriate pre-tax rate, risk specific to the liability.

Income tax comprises current and deferred tax. Income tax is recognized in the statement of loss except to the extent that it relates to a business combination or to items recognized directly in equity, in which case the income tax is also recognized directly in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted, at the end of the reporting period, and any adjustment to tax payable in respect of previous years.

In general, deferred tax is recognized in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined on a non-discounted basis using tax rates and laws that have been enacted or substantively enacted at the balance sheet date and are expected to apply when the deferred tax asset or liability is settled. Deferred tax assets are recognized to the extent that it is probable that the assets can be recovered.

Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, except, in the case of subsidiaries, where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities, when they relate to income taxes levied by the same taxation authority and when the Company intends to settle its current tax assets and liabilities on a net basis.

Share capital issued as non-monetary consideration is recorded at an amount based on fair market value of the shares issued.

The proceeds from the issue of units is allocated between common shares and common share purchase warrants on a pro-rated basis on a relative fair value as follows: the fair value of common shares is based on the price at market close on the date the units are issued and the fair value of the common share purchase warrants is determined using a Black-Scholes pricing model.

All stock-based awards made to employees and non-employees are measured and recognized using the Black-Scholes fair value based method. For employees, the Company recognizes stock based compensation expense based on the estimated fair value of the options on the date of the grant. For non-employees, the fair value of the options is based on the fair value of services received and recognized at the time of services rendered. The fair value of the options is recognized over the vesting period of the options granted as stock based compensation expense and corresponding adjustment to contributed surplus. The number of options expected to vest is periodically reviewed and the estimated option forfeiture rate is adjusted as required throughout the life of the option. Upon exercise these amounts are transferred to share capital.

Basic loss per share is computed by dividing loss attributable to common shareholders by the weighted average number of common shares outstanding during the period. The computation of diluted earnings per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on earnings per share. The dilutive effect of outstanding options and their equivalents are reflected in diluted earnings per share by application of the treasury stock method. Since the Company has losses, the assumed exercise of outstanding stock options has not been included in this calculation as it would be anti-dilutive.

The Company holds a 100% interest in certain mineral properties in El Salvador known as El Dorado. El Dorado is subject to a 3% net smelter return royalty. Pacific Rim has the right to buy back the royalty for $1 million for the first 1.5% and $3 million for the second 1.5%, provided that at least one half of the royalty is acquired within six months of the commencement of commercial production.

As of April 30, 2013, the Company has spent a cumulative total of $55,022 in El Salvador relating to exploration. Of this amount $41,547 has been sent directly to its wholly owned subsidiary, Pacific Rim El Salvador, S.A. De C.V.

An Environmental Impact Study has been submitted to governmental authorities for their consideration and requires approval before the exploration licence can be converted to an exploitation concession which is required to carry out mining in the licence area. In meeting its responsibilities, a mine design for the Company’s El Dorado gold project was submitted to the Government of El Salvador in its final form in October 2006. The issuance of the permit remains outstanding and consequently the Company has sought a legal remedy to secure its right to develop the El Dorado project.

On April 30, 2009 Pac Rim Cayman LLC, a Nevada corporation and a wholly-owned subsidiary of Pacific Rim Mining Corp. filed international arbitration proceedings against the Government of El Salvador (“GOES”) under CAFTA and the Investment Law in its own name and on behalf of its three wholly-owned El Salvadoran enterprises, Pacific Rim El Salvador, Sociedad Anónima de Capital Variable and Dorado Exploraciones, Sociedad Anónima de Capital Variable. The arbitration is administered under the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States and under the Rules of Procedure for Arbitration Proceedings of the ICSID. ICSID is an affiliate of the World Bank and is headquartered in Washington, D.C.

On May 31, and June 1, 2010, hearings on a preliminary objection filed by the GOES, which sought to dispose of nearly all of the claims brought by PacRim against the GOES under CAFTA and the Investment Law of El Salvador (“Investment Law”), were held. On August 2, 2010 the ICSID tribunal panel that is hearing the investment claims of PacRim against the GOES, and that presided over the Preliminary Objection hearings, ruled in favour of PacRim, rejecting all of the arguments made by the GOES in its Preliminary Objection.

Between May 2 and 4, 2011, hearings on a jurisdiction objection filed by the GOES in relation to PacRim’s action under CAFTA and the Investment Law took place at the ICSID headquarters in Washington, DC. The purpose of these objection hearings was for the ICSID Tribunal to hear objections filed by the GOES in August 2010 wherein the GOES asserted that ICSID did not have jurisdiction to hear PacRim's claims under CAFTA or the Investment Law based largely on timing and nationality issues. On June 1, 2012, the ICSID Tribunal issued its ruling on the Jurisdiction Objections and determined that PacRim’s Arbitration claim would proceed. The Tribunal confirmed ICSID (at the World Bank) has jurisdiction to hear PacRim’s claims under the Investment Law, but not under CAFTA. Accordingly, the Arbitration claim can and will proceed under the Investment Law alone. ICSID, a branch of the World Bank, will continue to adjudicate the case at its headquarters in Washington, DC.

The Company is unable to determine an outcome of its international arbitration proceedings against the GOES under the Investment Law. As at April 30, 2013, the Company has now incurred $6,309 relating to the arbitration proceedings.

The Company’s activities in El Salvador are subject to the effects of changes in legal, tax and regulatory regimes, national and local political issues, labour and economic developments and government bureaucracy. The Company has experienced lengthy delays in the processing of the El Dorado exploitation concession application and has commenced a legal claim under the Investment Law as noted above. In addition, because of the Investment Law dispute, the Company has not had the ability to confirm or renew its exploration licences as a result of the claims that are under the Investment Law arbitration. If the Company is unsuccessful in obtaining a permit for El Dorado or in its Investment Law claim, or is impacted by other factors beyond the control of the Company, this would adversely impact operations in El Salvador or result in the impairment of the El Dorado property in the future; such impairment could be material.

By agreement dated February 6, 2006, the Company agreed to acquire from a consortium of private companies a 100% interest in an El Salvador exploration concession to be known as the Zamora property. Upon TSX approval of the original agreement, the Company was required to make a payment of 50,000 shares (issued). The agreement was amended in September 2006 to include the acquisition of a 100% interest in the Cerro Colorado claims while maintaining the provisions in the agreement for the Company’s acquisition of the Zamora claims. The agreement was amended in February 2010 to adjust the fourth anniversary payment date to be the earlier of the date the Company receives confirmation that the Government of the Republic of El Salvador has granted a mining exploitation concession for the El Dorado Project and February 11, 2015. Under the terms of the amended agreement, the Company maintains an option to purchase the exploration concessions by making advance royalty payments as follows:

Upon TSX approval of the agreement:	100,000 shares plus 100,000 warrants of the Company (issued)
Advance payments:	The greater of:
First anniversary (shares issued)	100,000 shares or $100 in shares of the Company
Second anniversary (shares issued)	140,000 shares or $140 in shares of the Company
Third anniversary (shares issued)	200,000 shares or $200 in shares of the Company
Fourth payment - Payment date is earlier of the date the Company receives confirmation that the Government of the Republic of El Salvador has granted a mining exploitation concession for the El Dorado Project and February 11, 2015	300,000 shares or $300 in shares of the Company
Fifth payment – due on anniversary of fourth payment per February 2010 amended agreement and subsequent anniversaries	400,000 shares or $400 in shares of the Company

The advance royalty payments will continue until production is achieved or the exploration concessions expire. Title to 100% of the Cerro Colorado and Zamora claims will be transferred to the Company at such time as a positive production decision is made by the Company. Upon achievement of commercial production from the Cerro Colorado or Zamora claims, the vendor will receive a 3% net smelter royalty to a maximum purchase price of $10,000 (inclusive of the value of the advance royalty payments made).

The Company has also staked the other mining projects, including the Santa Rita project, located in El Salvador.

In 2011, the Company, through its US subsidiary Pacific Rim Exploration Ltd. (“PREx”), signed a Definitive Agreement with ICN Resources Ltd. (“ICN”) and Washoe Gold Inc. (“WGI”) to acquire a 65% interest in the Hog Ranch Property located in Washoe County, Nevada.

The Company, at its option, was required to spend an aggregate of $8 million in exploration expenditures and to issue an aggregate of one million common shares of Pacific Rim.

The Company decided not to proceed further with the Hog Ranch option agreement. The acquisition costs of $57 were written off during the year ended April 30, 2013.

The remaining 833,100 warrants had been issued to agents for services provided for a capital raising transaction and were not classified as a financial liability of the Company because they were accounted for under IFRS 2. The initial fair value of these warrants had been recognized as a share issuance cost and included in contributed surplus.

At April 30, 2013, there were 9,633,100 (April 30, 2012 – 33,164,100) warrants outstanding with a weighted average exercise price of Cdn$0.30.

The fair value of the warrants has been estimated at April 30 using the Black-Scholes option pricing model with the following weighted average assumptions:

Option pricing models require the input of subjective assumptions including the expected price volatility. Changes in the assumptions can materially affect the fair value estimate.

On October 3, 2012, the Company completed a non-brokered private placement with gross proceeds of $4,271 (Cdn $4,215) through the issuance of 42,150,000 common shares. The total share issuance costs relating to this transaction amounted to $36.

On May 3, 2011, the Company completed a private placement with gross proceeds of $3,897 (Cdn$3,696) through the issuance of 17,600,000 units. Each unit consisted of one share and one-half of one share purchase warrant. The Company allocated $3,239 to the common shares and $658 to the share purchase warrants based upon the relative fair values. Each warrant will entitle the holder to acquire one common share of the Company for a period of two years from the closing date at a price of Cdn$0.30.

The finders were issued a total of 233,400 units. The Company allocated $43 to the common shares and $9 to the share purchase warrants based upon the relative fair values. The finders were also issued 716,400 warrants, the warrants having the same terms as the warrants issued under the units and having a fair value of $67. The Company allocated $56 to the common shares and $11 to the share purchase warrants based upon the relative fair values.

The total share issuance costs relating to this transaction amounted to $142. The Company allocated $118 to the common shares and $24 to warrants derivative issuance costs.

The allocation of fair value of the units and warrants issued during the prior year was estimated using the Black-Scholes option pricing model with the following assumptions:

On August 29, 2006, shareholders adopted an evergreen incentive stock option plan (“2006 Plan”) whereby the maximum number of shares reserved for grant to Eligible Parties under the 2006 Plan is equal to 10% of the number of shares outstanding at the time of the grant.

The 3,660,000 options granted during the year ended April 30, 2013 have been allocated a total fair value of $301 with a weighted average fair value of Cdn$0.08. The allocation of fair value was estimated using the Black-Scholes option pricing model, with the following weighted average assumptions:

The total stock-based compensation recognized during the year ended April 30, 2013 was $361 (2012 - $454) with the offsetting entry to contributed surplus.

Option pricing models require the input of subjective assumptions including the expected price volatility. The expected share price volatility is estimated using historical daily share prices over the expected life of the option. Changes in the assumptions can materially affect the fair value estimate.

Details of the transactions between the Company and other related parties are disclosed below.

The Company’s Chief Financial Officer renders services to the Company through a company in which he is a partner.

The Company incurred the following fees and expenses in the normal course of operations in connection with related parties.

The remuneration of the directors, chief executive officer, chief financial officer, vice president of investor relations and vice president of exploration (collectively, the key management personnel) during the years ended April 30, 2013 and 2012 was as follows:

Income tax expense differs from the amount that would result from applying the Canadian federal and provincial income tax rate to earnings before income taxes. These differences result from the following items:

Unrecognized deductible temporary differences, unused tax losses, and unused tax credits are attributable to the following:

The Canadian federal and provincial statutory combined tax rate decreased to 25% due to legislative changes.

The Company has various losses and deferred exploration expenditures that are available for carry forward to reduce taxable income of future years. As at April 30, 2013, the Company has the following tax loss carry forwards and deductions, with respect to its Canadian and US operations and expire as follows:

In addition, the Company has incurred over $43 million in exploration expenditures in El Salvador that are not recognized because there is uncertainty surrounding mining tax legislation in El Salvador.

The Company’s business consists of a single reportable segment being mineral exploration and development. Details on a geographic basis are as follows:

“Mineral resource”	Refers to a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge.

	The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” used in this annual Form 20-F are Canadian mining terms as defined in accordance with NI 43-101 under the guidelines set out in the CIM Standards.

“Measured resource”	Refers to that part of a mineral resource for which quantity grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

“Indicated resource”	Refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

“Inferred resource”	Refers to that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

“Mineral reserve”	Refers to the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. The study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that might occur when the material is mined.

	Mineral reserves are categorized as follows on the basis of the degree of confidence in the estimate of the quantity and grade of the deposit.

“Proven reserve”	Means, in accordance with CIM Standards, for the part of a deposit which is being mined, or which is being developed and for which there is a detailed mining plan, the estimated quantity and grade or quality of that part of a measured mineral resource for which the size, configuration and grade or quality and distribution of values are so well established, and for which economic viability has been demonstrated by adequate information on engineering, operating, economic and other relevant factors, so that there is the highest degree of confidence in the estimate. This definition differs from the standards in the United States, where proven or measured reserves are defined as reserves which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; (b) grade and/or quality are computed from the results of detailed sampling and (c) the sites for inspection, sampling and measurement are spaced so closely and the geographic character is so well defined that size, shape, depth and mineral content of reserves are well established.

“Probable reserve”	Means, in accordance with CIM Standards, the estimated quantity and grade or quality of that part of an indicated mineral resource for which economic viability has been demonstrated by adequate information on engineering, operating, economic and other relevant factors, at a confidence level which would serve as a basis for decisions on major expenditures. This definition differs from the standards in the United States, where probable mineral reserves are defined as reserves for which quantity and grade and/or quality are computed from information similar to that of proven reserves (under United States standards), but the sites for inspection, sampling, and measurement are further apart or are otherwise less adequately spaced, and the degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation.

“Arbitration”	The arbitration claim initiated by Pac Rim Cayman, LLC, a Nevada, US-based wholly-owned subsidiary of the Company in respect of the El Dorado property, El Salvador
“BLM”	the United States Bureau of Land Management
“CAFTA”	The Dominican Republic-United States-Central America Free Trade Agreement
“CDN”	Canadian (usually in reference to currency)

“CIM”	Canadian Institute of Mining, Metallurgy and Petroleum
“Dore”	A compound containing gold and silver metal and various impurities
“Definitive Agreement”	The Hog Ranch agreement finalizing the terms of the Hog Ranch letter of intent, which grants the Company, through its US subsidiary Pacific Rim Exploration Ltd. the option to acquire a 65% interest in the Hog Ranch Property located in Washoe County, Nevada (see Item 4B – “Business Overview”).
“EIS”	Environmental Impact Study
“Evergreen Plan”	The Company’s Evergreen Incentive Stock Option Plan, originally established in 2006
“Final Agreement”	A proposed agreement that would finalize the terms of the Remance property letter of intent (see Item 4B – “Business Overview”). The Remance Final Agreement has not been signed.
“GOES”	The Government of El Salvador
“g/t” or “gpt”	Grams per tonne. One gram per tonne equals 0.02917 troy ounces per short ton
“NI 43-101”	National Instrument 43-101 - Standards of Disclosure for Mineral Projects. An instrument developed by the Canadian Securities Administrators (an umbrella group of Canada’s provincial and territorial securities regulators) that governs public disclosure by mining and mineral exploration issuers. The instrument establishes certain standards for all public disclosure of scientific and technical information concerning mineral projects
“ICSID”	The International Center for the Settlement of Investment Disputes
“Investment Law”	The Investment Law of El Salvador
“LOI”	Letter of Intent
“Ore”	A natural aggregate of one or more minerals which, at a specified time and place, may be mined and sold at a profit, or from which some part may be profitably separated
“OTCQX”	The United States-based OTCQX trading platform
“Qualified Person”	Conforms to that definition under NI 43-101 for an individual (a) to be an engineer or geoscientist with at least five years’ experience in mineral exploration, mine development or operation or mineral project assessment, or any combination of these; (b) with experience relevant to the subject matter of the mineral project and the technical report; and (c) is a member in good standing of a professional association that, among other things, is self-regulatory, has been given authority by statute, admits members based on their qualifications and experience, requires compliance with professional standards of competence and ethics and has disciplinary powers to suspend or expel a member

(1)	The Company used the Black-Scholes model as the methodology to calculate the grant date fair value, and relied on the following key assumptions and estimates for each calculation: expected dividend yield 0%, expected stock price volatility of 103% and 114%, risk free interest rate 1.26%, and expected life of options of between 3.5 and 4.8 years. The Company chose this methodology as it is the standard for exploration companies in Canada and has been consistently applied by the Company for valuing option-based awards since 2003. The stock-based awards are determined in Canadian funds and then translated into US funds at the fiscal 2013 average foreign currency exchange rate of $1.00US = $0.9822 CDN or $1.00 CDN = $1.018 US.
(2)	Mr. Shrake’s official annual salary is US$250,000 per year. Between November 2008 and September 2013, in light of economic and market conditions, Mr. Shrake voluntarily drew only US$180,000 in salary per year, representing 72% of his official salary. In September 2012 (during the current financial year), Mr. Shrake’s annual salary draw increased to US$200,000. See “President and Chief Executive Officer and Chairman’s Compensation” above.

	(g)	failure by the Company to obtain, in a form satisfactory to the executive, an effective assumption of its obligations hereunder by a successor to the Company, including a successor to a material portion of its business.

(1)	Relevant disclosure has been provided in the Summary Compensation Table above, for Mr. Shrake, a Director who is also a Named Executive Officer. Mr. Shrake’s total compensation is related to his role as CEO, and he receives no compensation for his services as a Director.
(2)	The Company’s three independent directors (Messrs. Myckatyn, Fagin and Baker) are entitled to receive annual directors’ compensation of CDN $10,000 plus 100,000 stock options but elected to forego the cash component of this compensation during the current financial year (only) in lieu of 120,000 additional compensatory stock options, which proposal was approved by the Board of Directors on October 3, 2012.
(3)	The Company used the Black-Scholes model as the methodology to calculate the grant date fair value, and relied on the following key assumptions and estimates for each calculation: expected dividend yield 0%, expected stock price volatility of 103% and 114%, risk free interest rate 1.26%, and expected life of options of between 3.5 and 4.8 years. The Company chose this methodology as it is the standard for exploration companies in Canada and has been consistently applied by the Company for valuing option-based awards since 2003.

1.	The Company, was formed on April 11, 2002 by the amalgamation of Dayton and Pacific Rim under the former Company Act (British Columbia). Now existing under the Business Corporations Act, S.B.C. 2002, c. 57 (British Columbia) (the “New Act”), as amended, the Company, is permitted to conduct any lawful business that it is not restricted from conducting by its Notice of Articles and Articles, neither of which contain any restriction on the business the Company may conduct.

2.	A director who has a disclosable interest in a proposed contract or transaction with the Company shall be liable to account to the Company for any profits that accrue to the director under or as a result of the contract or transaction unless disclosure is made thereof and the contract or transaction is approved in accordance with the provisions of the New Act. A director who holds a disclosable interest in a contract or transaction into which the Company has entered or proposes to enter into is not entitled to vote on any directors’ resolution to approve that contract or transaction, unless all the directors have a disclosable interest in that contract or transaction, in which case any or all of those directors may vote on such resolutions. The Articles of the Company permit an interested director to be counted in the quorum at the meeting whether or not the director votes on any or all of the resolutions considered at the meeting. The Company, if authorized by the board of directors, may borrow money, issue debt obligations and charge the assets of the Company, provided only that such power is exercised bona fide and in the best interests of the Company. There is no mandatory retirement age for directors. A director is not required to hold shares of the Company.

3.	The Company has only one class of common shares, without any special rights or restrictions. The dividend entitlement of a shareholder of record is fixed at the time of declaration by the board of directors. A vested dividend entitlement does not lapse, but unclaimed dividends are subject to a statutory six year contract debts limitation. Each common share is entitled to one vote on the election of each director. There are no cumulative voting rights, in consequence of which a simple majority of votes at the annual meeting can elect all the directors of the Company. Each common share carries with it the right to share equally with every other common share in dividends declared and in any distribution of surplus assets of the Company after payment to creditors on any winding up, liquidation or dissolution. There are no redemption or sinking fund provisions. All common shares must be fully paid prior to issue and are thereafter subject to no further capital calls by the Company. There exists no discriminatory provision affecting any existing or prospective holder of common shares as a result of such shareholder owning a substantial number of shares.

4.	Pursuant to the New Act and the Articles of the Company, the rights of shareholders may be changed only by the shareholders passing a special resolution approved by two-thirds (2/3) of the votes cast at a general meeting of the Company, the notice of which is accompanied by a circular describing the proposed action and its effect on the shareholders. Certain special resolutions provide that a shareholder may dissent in respect of the resolution, by sending a notice of dissent to the Company and otherwise complying with the provisions of the New Act. A shareholder who validly exercises such right of dissent in accordance with the New Act may have the shares that are subject of the notice of dissent purchased by the Company at their fair value.

5.	The board of directors must call an annual general meeting once in each calendar year and not later than 15 months after the last such meeting. The board may call an extraordinary general meeting at any time. Notice of such meetings must be accompanied by information circular describing the proposed business to be dealt with and making the required disclosure regarding the Company and the matters to be considered at the meeting. A shareholder or shareholders holding in the aggregate of 5% of the issued shares of the Company may requisition a meeting and the board is required to hold such meeting within four months of such requisition. Admission to such meetings is open to registered shareholders and their duly appointed proxy holders. Others may be admitted with the consent of the meeting.

6.	The constating documents of the Company contain no limitations on the rights of non-resident or foreign shareholders to hold or exercise rights on the shares of the Company.

7.	There are no provisions in the Company’s constating documents that would have an effect of delaying, deferring or preventing a change in control of the Company and that would operate only with respect to a merger, acquisition or corporate restructuring involving the Company or any of its subsidiaries.

8.	There are no provisions in the Company’s constating documents that govern the ownership threshold above which shareholder ownership must be disclosed.

9.	There is no limitation at law upon the right of a non-resident to hold shares in a Canadian company. However, the Investment Canada Act (Canada) (the “Investment Act”) requires certain non-Canadian individuals, governments, corporations, agencies or entities who wish to acquire “a Canadian business” or to establish a “new Canadian business” as those terms are defined in the Investment Act, to file a notification or an application for review with Investment Canada, a Canadian federal governmental agency. The Investment Act requires that certain acquisitions of control of a Canadian business by a non-Canadian must be reviewed by the Minister responsible for the Investment Act and approved on the basis that the Minister is satisfied that the acquisition is likely to be of net benefit to Canada, having regard to the criteria set forth in the Investment Act. The Investment Act makes the acquisition of control a reviewable event. The Investment Act sets out detailed rules for determining whether control has been acquired. The acquisition of one-third or more of the voting shares of a corporation may, in some circumstances, be deemed to constitute acquisition of control. A reviewable acquisition of control may not be implemented before being approved by the Minister. If not ultimately approved, a reviewable acquisition that has been completed may be subject to an order to divest, enforceable by injunction or a court order directing disposition of assets or shares.

10.	There are no provisions in the Company’s constating documents that govern changes in capital that are more stringent that required by law.

2.	The Advance Notice Policy fixes a deadline by which Shareholders must submit, in writing, nominations for directors to the Corporate Secretary of the Company prior to any annual or special meeting of Shareholders, and sets forth the specific information that such Shareholders must include with their nominations in order to be effective. Only persons who are nominated in accordance with the Advance Notice Policy are eligible for election as directors of the Company.

3.	For an annual meeting of Shareholders, notice to the Company must be not less than 30 days and not more than 65 days prior to the date of the annual meeting; provided, however, that in the event that the annual meeting is to be held on a date less than 50 days after the date on which the first public announcement of the date of such annual meeting was made, notice may be given not later than the close of business on the 10th day following such public announcement.

4.	For a special meeting of Shareholders (that is not also an annual meeting), notice to the Company must be given not later than the close of business on the 15^thday following the day on which the first public announcement of the date of such special meeting was made.

5.	The time periods for giving notice set forth above shall in all cases be determined based on the original date of the applicable annual meeting and/or special meeting of Shareholders, and in no event shall any adjournment or postponement of a meeting of Shareholders, or the reconvening of any adjourned or postponed meeting of Shareholders, or the announcement thereof, commence a new time period for the giving of notice as described above.
