Description of Business and Summary of Recent Events

PolyMet is a Toronto Stock Exchange and NYSE Amex listed Issuer engaged in the exploration and development, when warranted, of natural resource properties. The Company’s primary mineral property and principal focus is the commercial development of its NorthMet Project, a polymetallic project in northeastern Minnesota, USA which hosts copper, nickel, cobalt and platinum group metal mineralization.

The NorthMet Project covers a total of approximately 16,700 acres or 25.9 square miles comprising two areas: the NorthMet mine site totaling approximately 4,300 acres or 6.5 square miles of leased mineral rights and the Erie Plant site totaling approximately 12,400 acres or 19.4 square miles of freehold land located approximately six miles west of the mine site. The property is located in St. Louis County in the Mesabi Range District about 60 miles north of Duluth, Minnesota. The NorthMet Project is easily accessible via state and county roads. The surfaced County Highway 666 links the plant to the town of Hoyt Lakes, itself approximately 25 miles east of Virginia, Minnesota which is located on State Highway 53. The mine site is accessible by an all-season gravel road from the plant site and a private railroad crosses the property immediately south of the deposit and runs to the plant site. The plant site is serviced by commercial railroad which connects into the US national and Trans-Canadian railroad systems, as well as a private railroad providing access to port facilities located on Lake Superior. Three high-voltage power lines owned by Minnesota Power supply the plant site and there is ready access to industrial electric power at the mine site.

Asset Acquisitions

On November 15, 2005 the Company, through its Minnesota subsidiary (Poly Met Mining, Inc.), completed the early exercise of PolyMet’s option with Cliffs Natural Resources, Inc. (NYSE:CLF) (“Cliffs”) to acquire the Erie Plant, which is located 10 kilometers (6 miles) west of PolyMet’s NorthMet deposit. The plant was operated by Cliffs for many years and was acquired by Cliffs in early 2001 from LTV Steel Mining Company after that company’s bankruptcy at which time the plant was placed on care-and-maintenance with a view to a potential restart. With minor modification, the crushing and milling circuits can be used for the NorthMet ore. The plant assets now owned by PolyMet include crushing and milling equipment, comprehensive spare parts, plant site buildings, real estate, tailings impoundments and mine workshops, as well as access to extensive mining infrastructure including roads, rail, water, and power.

PolyMet plans to refurbish and reactivate the crushing, concentrating and tailings facilities at the Erie Plant to produce concentrates containing copper, nickel, cobalt and precious metals. The Company plans to sell separate copper and nickel concentrates prior to completion of construction and commissioning of the new hydrometallurgical metal recovery processing facilities. Once completed, the new hydrometallurgical plant will upgrade the nickel concentrates to produce a nickel-cobalt hydroxide and a precious metals precipitate.

On December 20, 2006 the Company acquired from Cliffs, property and associated rights sufficient to provide it with a railroad connection linking the mine development site and the Erie Plant. This transaction also included 120 railcars, locomotive fueling and maintenance facilities, water rights and pipelines, large administrative offices on site and an additional 6,000 acres of land to the east and west of and contiguous to its existing tailing facilities.

PolyMet indemnified Cliffs for ongoing reclamation and remediation associated with the property under both transactions.

In April 2010, Cliffs entered into a consent decree with the Minnesota Pollution Control Agency (“MPCA”) relating to alleged violations on the Cliffs Erie Property. This consent decree required submission of Field Study Plan Outlines and Short Term Mitigation Plans, which have been approved by the MPCA. In April 2012, long-term mitigation plans were submitted to the MPCA for its review and approval, such approval remains outstanding to date. As part of its prior transactions with Cliffs, PolyMet has agreed to indemnify Cliffs for certain on-going site environmental liabilities.

There is substantial uncertainty related to applicable water quality standards, the engineering scope and cost of mitigation required to meet those standards, and responsibility for the financial liability. As such, the Company is unable to estimate its potential liability for the Long Term Mitigation Plan at April 30, 2012. Outcomes that are unfavorable to PolyMet could result in material additional liability. The Company included its best estimate of the liabilities related to this consent decree in its environmental rehabilitation provision for the period ended April 30, 2012.

Environmental Review

In October 2005, the Minnesota Department of Natural Resources ("MDNR") published its Environmental Assessment Worksheet Decision Document establishing the MDNR as the lead state agency and the US Army Corps of Engineers (“USACE") as the lead federal agency (together the “Lead Agencies”) for preparation of an Environmental Impact Statement (“EIS”) for the project. In 2006 these Lead Agencies selected an independent environmental contractor (“the EIS Contractor”) to prepare the EIS. The EIS Contractor is Environmental Resources Management, a leading global provider of environmental, health and safety, risk, and social consulting services. The EIS Contractor team included members with expertise and experience in mining sulfidic ores. Several other government agencies (including the US Forest Service, the Bois Forte Band of Chippewa and the Fond Du Lac Band of Lake Superior Chippewa) joined the EIS preparation team as Cooperating Agencies, which brought their special expertise to the process.

Under state and federal guidelines and regulations, a Draft EIS identifies the environmental impact of a proposed project as well as evaluating alternatives and ways to mitigate potential impacts. PolyMet was involved in the process of alternative/mitigation development and had input into the technical and economical feasibility of potential alternatives and mitigations. The EIS Contractor prepared a series of preliminary versions of the Draft EIS that were reviewed and commented on by the Lead Agencies, other governmental agencies, and PolyMet.

In November 2009, the Lead Agencies published the PolyMet Draft EIS with formal notification of publication in the Minnesota Environmental Quality Board (“EQB”) Monitor and the Federal Register on November 2 and November 6, 2009, respectively. The formal notification of publication started a 90-day period for public review and comment, which ended on February 3, 2010. During this period, the lead Agencies held two public meetings – one in the town of Aurora, MN near the project location and one in Blaine, MN in the metropolitan Minneapolis-St. Paul area.

The Lead Agencies received more than 3,700 submissions containing approximately 22,000 separate comments, including an extensive comment letter from the US Environmental Protection Agency (“EPA”) in its role as reviewer of projects that could impact the environment.

On June 25, 2010 the Lead Agencies announced that they intend to complete the EIS process by preparing a Supplemental Draft EIS that incorporates the proposed US Forest Service ("USFS") land exchange and expands government agency cooperation. The USFS joined the USACE as a federal co-lead agency through the completion of the EIS process. In addition, the EPA joined the effort as a cooperating agency. The MDNR remains the state co-lead agency.

On October 13, 2010 the USACE and the USFS published a Notice of Intent to complete the Supplemental Draft EIS, which:

Supplements and supersedes the Draft EIS and respond to concerns identified by the EPA and other comments on the Draft EIS.
Incorporates potential effects from the proposed land exchange between the USFS Superior National Forest and PolyMet.

Public review of the scope of the land exchange ended on November 29, 2010. The Notice of Intent stated that the proposed land exchange would eliminate conflicts between the United States and private mineral ownership and consolidate land ownership to improve Superior National Forest management effectiveness and public access to federal lands. The proposed exchange is in accordance with Forest Service Strategic Plan Goals to provide and sustain long-term socioeconomic benefits to the American people, conserve open space, and sustain and enhance outdoor recreation activities.

The NorthMet mine site encompasses approximately 2,840 of the 6,650 acres of land proposed for exchange to private ownership; the remaining federal property would improve intermingled and inefficient ownership patterns and eliminate conflicts if minerals development were to expand in the future.

The lands that would be received by the Superior National Forest consist of forest and wetland habitat as well as lake frontage. These lands would enhance public recreation opportunities and complement existing federal ownership by eliminating or reducing private holdings surrounded by Superior National Forest land.

Once the Supplemental Draft EIS (“SDEIS”) is completed, it will be made available for public review prior to preparation of the final EIS. Completion of the final EIS and a subsequent Adequacy Decision by the DNR and Record of Decision by the federal agencies are necessary before the land exchange can occur and various permits required to construct and operate the project can be issued. The major permits are:

Prior to receipt of the permits, the Company intends to secure construction financing that would be available upon receipt of key permits, with construction slated to start upon availability of construction finance. Construction of NorthMet is expected to be made up of four major components:

	1.	Implementation of environmental safeguards;
	2.	Construction of the mine and reactivation of some existing mine infrastructure;
	3.	Refurbishment of the existing Erie Plant facilities and construction of new flotation facilities, and
	4.	Construction of a new hydrometallurgical plant.

Key Developments

On February 1, 2012 PolyMet reported on the status of the NorthMet environmental review. ERM, the Lead Agencies' environmental consultant, has completed a significant amount of work on the SDEIS, which will comprise nine chapters. The first four chapters, comprising over 400 pages and including more than 100 figures, have been drafted and are being reviewed by the Lead Agencies.

Other important milestones already achieved include:

Approval of air emission estimates.
Approval of cumulative visibility, acid deposition, and fiber impact evaluation reports.
Completion of geotechnical stability modeling with results now under review.
Completion of direct wetland impact evaluation and wetland mitigation plans, which are now under review.
Completion of hazardous materials assessment; threatened, endangered and sensitive species analysis; assessments of wildlife and heritage resources; and wetland/floodplain analysis reports for the lands involved in the land exchange, which have been delivered to the USFS for review.
Delivery by PolyMet of updated project documents including the detailed project description, mine plan, reclamation and waste disposal plans, and extensive data packages.

Since February 1, 2012 the Lead Agencies have completed their review of the initial chapters of the SDEIS, which are now being reviewed by the Cooperating Agencies. Completion of detailed environmental modeling, including quality assurance plans as well as generation, verification, review, and documentation of modeling data is underway.

On March 9, 2012 PolyMet entered into an option agreement over certain land that it plans to have restored to wetlands through an agreement with AG for Waterfowl, LLP ("AG"). PolyMet paid AG $2.0 million cash and issued 2,788,902 of its common shares and warrants to purchase 1,083,333 of its common shares at US$1.50 per share at any time until December 31, 2015. AG has provided the Company security over its requirement to perform the wetlands conversion work in the form of a $5.9 million face value five year zero interest rate mortgage over land currently in agricultural use that AG will restore to wetlands in order to earn wetland credits. The mortgage will be proportionately released as part of the lands are fully restored to approved wetland status, at which time PolyMet will receive formal wetland credits. Any lands that PolyMet has not requested be restored to wetland will revert to AG and the remaining mortgage, if any, will be released on February 28, 2017. PolyMet is committed to pay AG an additional $0.680 million over seven years as compensation for the work AG is continuing to undertake.

On May 23, 2012 PolyMet reported on the status of the NorthMet environmental review. The Lead Agencies are updating the schedule for completion of the NorthMet EIS and provisionally expect to publish the supplemental draft EIS in the first quarter of 2013, with a preliminary supplemental draft EIS available for review by the Cooperating Agencies two-to-three months before that. The process to complete the environmental review is:

Complete rigorous Lead Agency review and quality assurance/quality control process for the environmental models.
Incorporate engineering refinements into the models to show that the project will meet all relevant state and federal standards, including the wild rice sulfate standards.
Incorporate comments from the Cooperating Agencies including the US Environmental Protection Agency (EPA) into the supplemental draft EIS which will be released for public review and comment.
Prepare and release the final EIS, which must be done before permitting decisions can be made.

On June 14, 2012 PolyMet reported that the British Columbia Securities Commission (the “BCSC”) has reviewed select matters related to the Company’s continuous disclosure record. As a result of that review, the Company received comments from the BCSC identifying certain technical disclosure issues, in particular in the Company’s National Instrument 43-101 (“NI 43-101”) Technical Report on the NorthMet Deposit, Minnesota, USA, dated September 2007. In order to address these issues, PolyMet plans to file a new Technical Report under NI 43-101, which will fully support the information set out below. This new Technical Report will be filed on SEDAR upon completion.

During the three month period ended April 30, 2012, the Company granted 1,250,000 options (April 30, 2011 – 750,000) to directors and management.

Results of Operations

For the three months ended April 30, 2012 (the “2013 first quarter”) compared to the three months ended April 30, 2011 (the “2012 first quarter”)

a) Loss for the Period:

During the three months ended April 30, 2012, the Company incurred a loss of $1.250 million ($0.01 loss per share) compared to a loss of $1.319 million ($0.01 loss per share) during the three months ended April 30, 2011. The decrease in the net loss for the period was primarily attributable to the following:

a decrease in professional fees in the current year period to $82,000 (prior year period - $205,000) primarily due to transition to IFRS in the 2012 first quarter;
a decrease in finance income and costs in the current year period to $9,000 (prior year period - $172,000) primarily due to the reduction in ARO accretion as a result of the increase in the environmental rehabilitation provision due to decreases in the relevant discount rate.

These items were partially offset by the following:

an increase in share based compensation in the current year period to $616,000 (prior year period - $536,000) relating to board and other management changes;
an increase in office expenses and corporate wages to $248,000 (prior year period - $184,000) primarily due to one-time costs related to opening a head office in St. Paul, Minnesota.

b) Cash Flows:

Cash used in operating activities in the three months ended April 30, 2012 was $0.504 million compared to cash used in the three months ended April 30, 2011 of $1.101 million. The variance in cash is primarily due to changes in non-cash working capital balances and the above noted operating variances.

Cash provided by financing activities for the three months ended April 30, 2012 was $148,000 compared to cash used in the three months ended April 30, 2011 of $437,000. The variance in cash is primarily due to prior year period scheduled repayment of $500,000 debt. 2013 first quarter activity included the issuance of share capital on the exercise of stock options for $148,000 (prior year period - $67,000).

Cash used in investing activities for the three months ended April 30, 2012 was $6.188 million compared to cash used in the three months ended April 30, 2011 of with $2.914 million. The increase was primarily due to entering into an option agreement to obtain wetland credits to be used to develop the mining property for cash in the amount of $2.092 million (prior year period –nil) and certain other non-cash consideration.

Total cash for the three months ended April 30, 2012 decreased by $6.544 million for a balance of $10.934 million compared to the three months ended April 30, 2011 where cash decreased $4.452 million to a balance of $5.909 million.

Financing Activities

On August 27, 2009 the Company announced that it had filed a universal shelf registration on Form F-3 with the U.S. Securities and Exchange Commission (“SEC”). This universal shelf registration allows PolyMet to have the option to offer and sell, from time to time in one or more offerings, up to $500 million of its debt securities, common shares, warrants and units.

Since October 31, 2008 the Company and Glencore AG (“Glencore”) have entered into a series of financing agreements and a marketing agreement whereby Glencore committed to purchase all of the Company’s production of concentrates, metal, or intermediate products on market terms at the time of delivery, for at least the first five years of production. PolyMet agreed to propose to shareholders the election of Stephen Rowland, a senior executive of Glencore, as a director and also appointed a senior member of Glencore's technical team to PolyMet's Technical Steering Committee. As a result of the series of financing transactions and the purchase by Glencore of PolyMet common shares previously owned by Cliffs, Glencore's current and potential ownership of PolyMet comprises:

41,967,842 shares representing 23.6% of PolyMet's issued shares
$25 million initial principal floating rate secured debentures due September 30, 2014. Including capitalized interest as of March 31, 2012, these debentures are exchangeable at $1.50 per share into 19,510,196 common shares of PolyMet upon PolyMet giving Glencore notice that it has received permits necessary to start construction of the NorthMet project and availability of senior construction finance in a form reasonably acceptable to Glencore.
Glencore has subscribed to 5 million common shares at $2.00 per share to be issued no later than October 15, 2012.
Glencore holds warrants to purchase 5.6 million common shares at $1.50 per share at any time until December 31, 2015, subject to mandatory exercise if the 20-day Value Weighted Average Price (“VWAP”) of PolyMet common shares is equal to or greater than 150% the exercise price and PolyMet provides notice to Glencore that it has received permits necessary to start construction of the North Met Project and availability of senior construction finance, in a form reasonably acceptable to Glencore.

If Glencore were to exercise all of its rights and obligations under these agreements, it would own 72,078,038 common shares of PolyMet, representing 34.7% on a partially diluted basis, that is, if no other options or warrants were exercised.

Proceeds from private placement financings with Glencore were used for Mineral PP&E investments, loan repayments, and general corporate expenditures. As at April 30, 2012, approximate proceed usage was as follows:

On June 30, 2011 PolyMet closed a $4.000 million loan from the IRRRB. At the same time, the Company exercised its options to acquire two tracts of land totaling approximately 5,300 acres of forests, wetlands, and lakes with high recreational value that are included as part of the proposed land exchange with the USFS. The loan is secured by the land acquired, carries a fixed interest rate of 5% per annum, compounded annually if not paid, and is repayable on the earlier of June 30, 2016 or the date which the related land is exchanged with the USFS. PolyMet has issued warrants giving the IRRRB the right to purchase 400,000 shares of its common shares at $2.50 per share at any time until the earlier of June 30, 2016 or one year after permits are received.

On March 9, 2012 the Company acquired a secured interest in land owned by AG for Waterfowl, LLP ("AG") that is permitted for restoration to wetland. AG will restore the wetlands and, upon completion, wetland credits will be issued by the proper governmental authorities. The Company plans to use the wetland credits to offset wetlands disturbed during construction and operation of the NorthMet Project. The Company holds a first mortgage on the land, which will be proportionately released as wetland credits are transferred to the Company. The Company has the option to exercised individually five separate phases of wetland credit development. Any options not exercised by February 28, 2017 will expire and the remaining mortgage, if any, will be released. As at April 30, 2012, the Company had exercised the option on Phase 1.

The Company paid AG initial consideration of $2.0 million cash and issued 2,788,902 of the Company’s common shares (of which 371,854 held in escrow pending Phase 1 completion) and a warrant to purchase 1,083,333 of the Company’s common shares at $1.50 per share at any time until December 31, 2015 as consideration for a $5.9 million mortgage to secure performance by AG. In addition to the initial consideration, performance commitments for Phase 1 totaling $0.68 million will be due over the seven years following wetland construction completion for ongoing maintenance by AG. Performance payments totaling $1.063 million per phase for completion and maintenance of Phase 2 to 5 will only be incurred if and when the Company initiates development of those phases, and will be due over seven years from the completion of each phase. If wetland credits are issued before the seven-year anniversary, any unpaid amounts are due upon issuance of the wetland credits.

The transaction was negotiated between unrelated parties and therefore the Company has concluded the fair value of the services should be allocated between the $2.0 million cash payment, the $3.9 million equity instruments, and $4.933 million in future performance payments. Since the Company expects to exercise each of the remaining options prior to expiration, the Company determined that the total consideration price of approximately $10.833 million should be allocated equally amongst the total credits. Since there is a market for wetland credits, the Company could sell some or all to third parties. To date the company has recorded the shares, warrants and cash paid, including transaction costs, as a charge of $5,992,173 to Wetland Credit Intangibles, which will be tested for impairment indicators at each reporting date and amortized on a systematic basis over their useful lives, once they are completed and available for use.

During the three months ended April 30, 2012 the Company issued 185,000 shares (prior year period – 95,000) upon exercise of options for proceeds of $148,000 (prior year period - $67,000). During the three months ended April 30, 2012, PolyMet also issued 20,000 shares (prior year period – 75,000) as partial payment for options to purchase land.

Liquidity and Capital Resources

As at April 30, 2012 the Company had working capital of $9.509 million compared with working capital of $16.375 million at January 31, 2012 consisting primarily of cash of $10.934 million (January 31, 2012 - $17.478 million), trade and other receivables of $0.707 million (January 31, 2012 - $0.440 million), prepaid expenses of $0.507 million (January 31, 2012 - $0.934 million), accounts payable and accrued liabilities of $1.840 million (January 31, 2012 - $1.679 million), and the current portion of asset retirement obligations of $0.828 million (January 31, 2012 - $0.828 million).

The Company expects to pay the $4 million IRRRB loan plus capitalized interest and convertible debt principal balance of $25 million plus capitalized interest from working capital, additional financing and funds from operations once commercial production has commenced. The Company’s cash is primarily held in deposits and bearer deposits of a major Canadian bank and does not include any exposure to asset-backed commercial paper.

As at April 30, 2012 the Company, has obligations to issue shares under the Company’s Bonus Share Plan. The Company has received shareholder approval for the Bonus Shares of Milestones 1 – 4 and regulatory approval for Milestones 1, 2 and 3. Milestone 4 is subject to regulatory approval. To April 30, 2012, 5,240,000 shares have been issued for the achievement of Milestones 1, 2 and 3. The bonus shares allocated for Milestones 1 through 3 are valued using the Company’s closing trading price on May 28, 2004 of CDN$0.75 per share, the date of the approval of the bonus plan by the disinterested shareholders. The bonus shares allocated for Milestone 4 are valued using the Company’s closing trading price on June 17, 2008 of US$3.80 per share, the date of the approval of the bonus plan by the disinterested shareholders.

As at June 8, 2012, the Company has outstanding commitments related to wetland credit intangibles, rent, consultants and the environmental review process of approximately $1.400 million with approximately half due over the next year and the remainder due over seven years

The consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and the settlement of liabilities in the normal course of operations.

Should the Company wish to continue to further advance the NorthMet Project to commercial production PolyMet will require additional funds. As the Company has no operating revenues, the only source of liquidity consists primarily of cash from proceeds of project debt, other debt and equity financing.

Financial Instruments and Risk Management

The carrying values of the Company’s financial instruments are classified into the following categories:

		April 30,	January 31,
		2012	2012
Loans and Receivables ⁽¹⁾	$	10,934	17,478
Available-for-sale		29	30

Other financial liabilities ⁽²⁾		34,976	34,369

(1)	Includes cash and equivalents.
(2)	Includes trade payables and accrued liabilities, convertible debt and long term debt.

The Company has determined the estimated fair values of its financial instruments based on appropriate valuation methodologies.

Risks Arising from Financial Instruments and Risk Management

The Company’s activities expose it to a variety of financial risks: market risk (including currency), credit risk, liquidity risk, interest rate risk and investment risk. Reflecting the current stage of development of the Company’s NorthMet Project, PolyMet’s overall risk management program focuses on facilitating the Company’s ability to continue as a going concern and seeks to minimize potential adverse effects on PolyMet’s ability to execute its business plan.

Risk management is the responsibility of executive management. Material risks are identified and monitored and are discussed with the audit committee and the board of directors.

Currency Risk

The Company incurs expenditures in Canada and in the United States. The functional and reporting currency of the Company and its subsidiary is the United States dollar. Foreign exchange risk arises because the amount of Canadian dollar cash and equivalents, trade and other receivables, investment or trade payables and accrued liabilities will vary in United States dollar terms due to changes in exchange rates.

As the majority of the Company’s expenditures are in United States dollars, the Company has kept a significant portion of its cash and equivalents in United States dollars. The Company has not hedged its exposure to currency fluctuations.

The Company was exposed to currency risk through the following assets and liabilities denominated in Canadian dollars:

		April 30,			January 31,
		2012			2012
Loans and receivables ⁽¹⁾	$	102		$	305

Based on the above net exposures, as at April 30, 2012, a 10% change in the Canadian / United States exchange rate would have impacted the Company’s loss by $18,000.

Credit Risk

Credit risk arises on cash and equivalents held with banks and financial institutions, as well as credit exposure on outstanding trade and other receivables. The maximum exposure to credit risk is equal to the carrying value of the financial assets of $11,641,000.

The Company’s cash and equivalents are held through a large Canadian financial institution.

Liquidity Risk

Liquidity risk arises through the excess of financial obligations over available financial assets due at any point in time. The Company’s objective in managing liquidity risk is to maintain sufficient readily available reserves in order to meet its liquidity requirements at any point in time. The Company achieves this by maintaining sufficient cash and equivalents.

Interest Rate Risk

Interest rate risk arises on cash and equivalents and long term debt and fluctuations in the related interest rates. The Company has not hedged any of its interest rate risk.

The Company was exposed to interest rate risk through the following assets and liabilities:

		April 30,		January 31,
		2012		2012
Loans and receivables ⁽¹⁾	$	10,934	$	17,478
Other financial liabilities ⁽²⁾	$	33,136	$	32,690

(1)	Includes cash and equivalents.
(2)	Represents long term debt and convertible debt.

Investment Risk

The Company’s investment in the common shares of a publicly traded Canadian mining company bears investment risk. The maximum exposure to investment risk is equal to the carrying value of the investment.

The Company's investment in the NorthMet Project is also at risk since the NorthMet Project is pledged in part as security to Cliffs and otherwise is pledged wholly as security to Glencore.

The Company was exposed to investment risk through the following assets:

		April 30,		January 31,
		2012		2012

Fair Value Measurements

PolyMet’s financial assets and liabilities are measured or disclosed at fair value on a recurring basis and classified in their entirety based on the lowest level of input that is significant to the fair value measurement. There are three levels of fair value hierarchy that prioritize the inputs to valuation techniques used to measure fair value, with level 1 inputs having the highest priority. The levels and the valuation techniques used to value the Company’s financial assets and liabilities are described below:

Level 1 –	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Investments in marketable securities are valued using quoted market prices in active markets, obtained from securities exchanges. Accordingly, these items are included in Level 1 of the fair value hierarchy.

Level 2 –	Quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 –	Unobservable (supported by little or no market activity) prices.

Loans and receivables are recorded at face value. Trade and other receivables are short-term in nature and represent the initial price of the good or service. Long term and convertible debt have been fair valued using assumptions with respect to interest rates relevant to similar debt taking into account the collateral involved.

The fair values of the Company's financial assets, loans and receivables and trade and other receivables approximate their carrying amounts. The Company’s investment is valued using quoted market prices in active markets, obtained from securities exchanges and accordingly is Level 1 in the fair value hierarchy.

The fair value of the Company's trade payables and accrued liabilities, long term debt and convertible debt approximate their carrying amounts.

Capital Management

Similar to other companies in the development stage, the Company is in discussions with certain parties to provide funding which will enable the Company to execute its business plan. With the completion of the DFS and taking into account the current permitting process the Company is in, PolyMet will require additional funds through Project construction. Funding for the Project could come from a number of sources and include internal cash flows (for the second stage of the construction), bank project financing and capital market financing. During the upcoming fiscal year, the Company’s objective is to identify the source or sources from which it will obtain the capital required to complete the Project.

The Company has no externally imposed capital requirements. In the management of capital, the Company includes the components of shareholders’ equity, convertible debt and long-term debt. The Company manages the capital structure and makes adjustments to it depending on economic conditions and the rate of anticipated expenditures. To maintain or adjust the capital structure, the Company may attempt to issue new shares, issue new debt, acquire or dispose of assets.

In order to assist in management of its capital requirements, the Company prepares expenditure budgets that are updated as necessary depending on various factors. The budgets are approved by the Company’s Board of Directors.

Although the Company plans to have the resources to carry out its plans and operations through April 30, 2013, it does not currently have sufficient capital to meet its estimated project capital expenditure requirements and is currently in discussions to arrange sufficient capital to meet these requirements.

Critical Accounting Estimates

The preparation of the consolidated financial statements in conformity with IFRS requires the use of certain critical accounting estimates. These critical accounting estimates require management to make assumptions and estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements.

Significant estimates used in the preparation of these consolidated financial statements include, amongst other things, expected economic lives of plant and equipment, anticipated costs of environmental rehabilitations including the reclamation of mine site, valuation of options, convertible debt and share purchase warrants, and the assessment of impairment in value of long lived assets. Actual results could differ from these estimates. The following discusses some of the most significant accounting estimates and judgements that the Company has made in the preparation of these consolidated financial statements:

(i) Determination of mineral reserves

Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s property. In order to estimate reserves, estimates are required about a range of geological, technical and economic factors, including quantities, production techniques, production costs, capital costs, transport costs, demand, prices and exchange rates. Estimating the quantity of reserves requires the size, shape and depth of deposits to be determined by analyzing geological data. This process may require complex and difficult geological judgments to interpret the data. As a result, management will form a view of forecast sales prices, based on current and long-term historical average price trends. Changes in the proven and probable reserves estimates may impact the carrying value of property, plant and equipment, restoration provisions, recognition of deferred tax amounts and depreciation, depletion and amortization.

(ii) Asset values and impairment charges

If the recoverable amount of an asset or cash-generating unit is estimated to be less than its carrying amount, the carrying amount of the asset or cash-generating unit is reduced to its recoverable amount. An impairment loss is recognized immediately in the statement of loss and comprehensive loss. Management’s determination of recoverable amounts include estimates of sales volumes and prices, costs to sell, recoverable reserves, operating costs and capital costs, which are subject to certain risks and uncertainties that may affect the recoverability of an asset’s costs. Although management has made its best estimate of these factors, it is possible that changes could occur that could adversely affect management’s estimate of the net cash flow to be generated from its assets or cash-generating unit.

For its mining property interest the Company considers both external and internal sources of information in assessing whether there are any indications of impairment. External sources of information the Company considers include changes in the market, economic and legal environment in which the Company operates that are not within its control and affect the recoverable amount of mining property interests. Internal sources of information the Company considers include indications of economic performance of the asset. In determining the recoverable amounts of the Company’s mining property interest, the Company’s management makes estimates of the discounted future after-tax cash flows expected to be derived from the Company’s property, costs to sell the mining property and the appropriate discount rate. Reductions in price forecasts, increases in estimated future costs of production, increases in estimated future non-expansionary capital expenditures, reductions in the amount of recoverable reserves and resources, and/or adverse current economics can result in a write-down of the carrying amounts of the Company’s mining interest.

Tabular amounts in thousands of U.S. Dollars except for price per share, shares and options

(iii) Estimated Reclamation and Closure Costs

The Company’s provision for reclamation and closure cost obligations represents management’s best estimate of the present value of the future cash outflows required to settle the liability which reflects estimates of future costs, inflation, and assumptions of risks associated with the future cash outflows, and the applicable risk-free interest rates for discounting the future cash outflows. Changes in the above factors can result in a change to the provision recognized by the Company. Changes to reclamation and closure cost obligations are recorded with a corresponding change to the carrying amounts of the related mining property. Adjustments to the carrying amounts of the related mining property can result in a change to future depletion expense.

Recent Accounting Pronouncements

The IASB issued the following standards which have not yet been adopted by the Company: IFRS 9, Financial instruments - Classification and Measurement, IFRS 10, Consolidated Financial Statements, IFRS 11, Joint Arrangements IFRS 12, Disclosure of Interests in Other Entities, and IFRS 13, Fair Value Measurement. Each of the new standards is effective for annual periods beginning on or after January 1, 2013, except for IFRS 9 which is effective for annual periods beginning on or after January 1, 2015, with early adoption permitted. The Company has not yet begun the process of assessing the impact that the new and amended standards will have on its consolidated financial statements or whether to early adopt any of the new requirements.

The following is a brief summary of these new standards:

IFRS 9 – Financial instruments - classification and measurement

This is the first part of a new standard on classification and measurement of financial assets that will replace IAS 39, Financial Instruments: Recognition and Measurement. IFRS 9 has two measurement categories: amortized cost and fair value. All equity instruments are measured at fair value. A debt instrument is at amortized cost only if the entity is holding it to collect contractual cash flows and the cash flows represent principal and interest. Otherwise it is at fair value through profit or loss. Requirements for financial liabilities were added to IFRS 9 in October 2010. Most of the requirements for financial liabilities were carried forward unchanged from IAS 39. However, some changes were made to the fair value option for financial liabilities to address the issue of own credit risk.

IFRS 10 – Consolidation

IFRS 10 requires an entity to consolidate an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Under existing IFRS, consolidation is required when an entity has the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities. IFRS 10 replaces SIC-12 Consolidation—Special Purpose Entities and parts of IAS 27 Consolidated and Separate Financial Statements.

IFRS 11 - Joint Arrangements

IFRS 11 requires a venturer to classify its interest in a joint arrangement as a joint venture or joint operation. Joint ventures will be accounted for using the equity method of accounting whereas for a joint operation the venturer will recognize its share of the assets, liabilities, revenue and expenses of the joint operation. Under existing IFRS, entities have the choice to proportionately consolidate or equity account for interests in joint ventures. IFRS 11 supersedes IAS 31, Interests in Joint Ventures, and SIC-13, Jointly Controlled Entities—Non-monetary Contributions by Venturers.

IFRS 12 – Disclosure of Interests in Other Entities

IFRS 12 establishes disclosure requirements for interests in other entities, such as joint arrangements, associates, special purpose vehicles and off balance sheet vehicles. The standard carries forward existing disclosures and also introduces significant additional disclosure requirements that address the nature of, and risks associated with, an entity’s interests in other entities.

IFRS 13 - Fair Value Measurement

IFRS 13 is a comprehensive standard for fair value measurement and disclosure requirements for use across all IFRS standards. The new standard clarifies that fair value is the price that would be received to sell an asset, or paid to transfer a liability in an orderly transaction between market participants, at the measurement date. It also establishes disclosures about fair value measurement. Under existing IFRS, guidance on measuring and disclosing fair value is dispersed among the specific standards requiring fair value measurements and in many cases does not reflect a clear measurement basis or consistent disclosures.

Shareholder Rights Plan

Effective May 25, 2007, the Company adopted an updated Shareholder Rights Plan (“Rights Plan”), which was approved by the Company’s shareholders on June 27, 2007, and modified by the Company’s shareholders on June 17, 2008, and reapproved by the Company's shareholders on July 13, 2011. Under the Rights Plan, the Company has issued one right for no consideration in respect of each outstanding common share of the Company to all holders of record of common shares on December 4, 2003. All common shares subsequently issued by the Company during the term of the Rights Plan will have one right represented for each common share held by the shareholder of the Company. The term of the Rights Plan is 10 years, unless the rights are earlier redeemed or exchanged. The Rights issued under the Rights Plan become exercisable only if a party acquires 20% or more of the Company's common shares without complying with the Rights Plan or without the approval of the Board of Directors of the Company.

Each Right entitles the registered holder thereof to purchase from the Company on the occurrence of certain events, one common share of the Company at the price of CDN$50.00 per share, subject to adjustment (the “Exercise Price”). However, if a Flip-in Event (as defined in the Rights Plan) occurs, each Right would then entitle the registered holder to receive, upon payment of the Exercise Price, that number of common shares that have a market value at the date of that occurrence equal to twice the Exercise Price. The Rights are not exercisable until the Separation Time as defined in the Rights Plan.

Off Balance-Sheet Arrangements

The Company does not utilize off-balance sheet arrangements.

Risks and Uncertainties

An investment in the Company’s common shares is highly speculative and subject to a number of risks and uncertainties. Only those persons who can bear the risk of the entire loss of their investment should participate. An investor should carefully consider the risks described in PolyMet’s Form 20-F/Annual Information Form for the year ended January 31, 2012 on file with the SEC and Canadian securities regulators and other information filed with the Canadian and United States securities regulators before investing in the Company’s common shares. The risks described in PolyMet’s Form 20-F/Annual Information Form are not the only ones faced. Additional risks that the Company currently believes are immaterial may become important factors that affect the Company’s business. If any of the risks described in PolyMet’s Form 20-F/Annual Information Form for the year ended January 31, 2012 occur, the Company’s business, operating results and financial condition could be seriously harmed and investors could lose all of their investment.

Disclosure controls and procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted by the Company under U.S. and Canadian securities legislation is recorded, processed, summarized and reported within the time periods specified in those rules, including providing reasonable assurance that material information is gathered and reported to senior management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to permit timely decisions regarding public disclosure. Management, including the CEO and CFO, has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) and15d-15(e) of the US Exchange Act and the rules of Canadian Securities Administration, as at January 31, 2012. Based on this evaluation, the CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective.

Management’s Responsibility for Financial Statements

The information provided in this report including the financial statements, is the responsibility of management. In the preparation of these statements, estimates are sometimes necessary to make a determination of future values for certain assets or liabilities. Management believes such estimates have been based on careful judgments and have been properly reflected in the accompanying financial statements.

Management maintains a system of internal controls to provide reasonable assurances that the Company’s assets are safeguarded and to facilitate the preparation of relevant and timely information.

Management’s report on internal control over financial reporting

The Company’s management is responsible for establishing and maintaining adequate internal controls over financial reporting. Any system of internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

There have been no changes in the Company’s internal control over financial reporting during the three month period ended April 30, 2012 that have materially affected, or are reasonably likely to material affect, its internal control over financial reporting.
