REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

To the Plan Administrator of the

Stillwater Mining Company 401(k) Plan

We have audited the accompanying statements of net assets available for benefits of the Stillwater Mining Company 401(k) Plan (the “Plan”) as of December 31, 2010 and 2009, and the related statement of changes in net assets available for benefits for the year ended December 31, 2010. These financial statements and the supplemental schedule are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes 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 Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2010 and 2009, and the changes in net assets available for benefits for the year ended December 31, 2010 in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets (Held at End of Year) as of December 31, 2010 is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the U.S. Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

STILLWATER MINING COMPANY 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

NOTE 1 – DESCRIPTION OF PLAN AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Plan

On June 1, 1993, Stillwater Mining Company (the “Company” or “Employer”) established the Stillwater Mining Company 401(k) Plan (the “Plan”). The following description of the Plan provides general information only. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan, covering all non-union employees of the Company, as defined in the Plan document, and is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). An employee is eligible to participate in the Plan at the beginning of the month following the employee’s date of hire.

Plan and Trust Administration

The administration of the Plan is the responsibility of the Company. The assets of the Plan are maintained in a trust fund that is administered under a trust agreement with State Street Bank and Trust Company.

Contributions

Each participant has the option to make pre-tax “elective deferral contributions” to the Plan of not less than 1% nor more than 60% of eligible compensation, as defined by the Plan document. The Company contributes an amount equal to 100% of each participant’s elective deferral contribution, up to 6% of the participant’s compensation, for the contribution period. The Company matching contributions may be made in Company common stock or cash. During 2010, all Company matching contributions were made in the form of common stock, except for $126,778, which was paid through the application of forfeitures into the interest bearing cash portion of the unitized Stillwater Mining Company common stock fund. Each participant also has the option to make after-tax contributions to the Plan of not less than 1% nor more than 10% of eligible compensation.

The Company may make annual discretionary profit sharing contributions during each Plan year. Profit sharing contributions are allocated to participants based on the ratio of each participant’s eligible compensation to the total compensation paid to all eligible participants for the Plan year. There was no discretionary contribution made during the year ended December 31, 2010.

During 2010, certain participants age 50 and over made catch-up contributions totaling $88,552.

Participant Accounts

Each participant’s account is adjusted for the participant’s contributions and allocations of (a) the Company’s matching contribution, (b) Plan earnings and losses, (c) discretionary contributions by the Company, and (d) an allocation of administrative expenses. Allocations of Plan earnings and losses are based on individual participant account balances. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Investment Options

Upon enrollment in the Plan, a participant directs contributions to any investment option offered. Participants may change their investment options and make transfers between investment options daily.

STILLWATER MINING COMPANY 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

Vesting

Participants are at all times fully vested in their voluntary contributions plus net actual earnings thereon. Vesting in Employer contributions is based on years of continuous service. Participants become 100 percent cliff vested after three years of service.

Notes Receivable from Participants

Participants may borrow from their fund accounts the lesser of: (a) $50,000 (reduced by the excess (if any) of the highest outstanding balance of loans during the one year period ending on the day before the loan is made, over the outstanding balance of loans from the Plan on the date the loan is made); or (b) 50% of the participant’s vested balance. The notes receivable are secured by the balance in the participant’s account and bear interest at rates that range from 5.25% to 10.25%. Interest rates are comparable to the rate charged by commercial lenders in the geographical area for similar loans on the origination date. Principal and interest is paid ratably through payroll deductions.

Payment of Benefits

Upon termination, retirement, or death, participants (or their beneficiaries) may elect to receive an amount equal to the vested value of their account in either a lump-sum amount or in installments determined by the participants or their beneficiaries. Vested accounts for terminated employees which do not exceed $5,000, but are greater than $1,000, are automatically rolled over into an individual retirement account (“IRA”). Accounts which are $1,000 or less are automatically distributed in a lump-sum.

Forfeitures

Forfeitures of terminated participants’ non-vested accounts are retained in the Plan and used to pay administrative expenses and reduce future Company matching contributions. As of December 31, 2010 and 2009, forfeited non-vested accounts totaled $183,954 and $198,216, respectively. During 2010, $109,701 of Employer matching contributions were forfeited by employees who terminated before those amounts became vested. Net earnings related to forfeited funds in 2010 totaled $12,857. The amount of forfeitures used to pay administrative expenses in 2010 totaled $9,630. The amount of forfeitures used to reduce Employer matching contributions in 2010 totaled $126,778. The amount of forfeitures used for corrective contributions in 2010 totaled $412.

Plan to Plan Transfers

The Company also sponsors the Stillwater Mining Company Bargaining Unit 401(k) Plan, which covers union employees of the Company (as defined by the Plan document). Transfers to and from this Plan occur when the union membership status of an employee changes. There was a net transfer into the Plan of $1,380,683 for the year ended December 31, 2010.

STILLWATER MINING COMPANY 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

Significant Accounting Policies

Basis of Accounting

The Plan’s financial statements have been prepared using the accrual method of accounting in accordance with U.S. generally accepted accounting principles (“US GAAP”).

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic No. 962, Plan Accounting – Defined Contribution Plans, requires the Plan to report investment contracts at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. Therefore, the Statements of Net Assets Available for Benefits present the fair value of the investment contract as well as the adjustment of the fully benefit-responsive investment contract from fair value to contract value. The Statement of Changes in Net Assets Available for Benefits is prepared on a contract value basis.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Risks and Uncertainties

The Plan invests in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.

Investment Valuation and Income Recognition

The Plan’s investments in mutual funds and common stock are stated at fair value based on the quoted market value or quoted share price at the end of the year. Plan investments in blended investment funds are valued based on the quoted market values of the underlying investments at the end of the Plan year, except for the guaranteed interest account included in the blended investment funds, which is valued as described below. The fair value of the guaranteed interest account is calculated by Massachusetts Mutual Life Insurance Company (“MassMutual”), a party-in-interest to the Plan (see note 5). The market value formula used by MassMutual is the same as a serial bond valuation formula for a bond which repays its original principal in installments, pays interest on the outstanding principal, and is being valued in the current interest rate environment. Purchases and sales of investments are recorded on a trade date basis.

Dividends are recorded as of the ex-dividend date. Interest income is recorded on the accrual basis. The Plan presents in the Statement of Changes in Net Assets Available for Benefits the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains (losses) and the unrealized appreciation (depreciation) of those investments.

Notes Receivable from Participants

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest, and are secured by the participants’ account balances. Interest income is recognized over the terms of the notes at the rate specified in the loan documents. Fees related to notes receivable from participants are recorded as administrative expenses when they are incurred. If a participant defaults, the carrying amount of the note receivable from the participant is eliminated and a benefit payment is recorded at the time the participant has a distributable event. Notes receivable mature between January 2011 and August 2020. As of December 31, 2010 and 2009, notes receivable from participants were $1,334,482 and $1,097,278, respectively.

STILLWATER MINING COMPANY 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

Expenses of the Plan

The Company may pay expenses incurred in the administration of the Plan at its discretion. A portion of the expenses are paid with forfeitures, although some expenses, including but not limited to, audit and legal fees and other administrative costs, may be paid by the Company.

Payment of Benefits

Benefits are recorded when paid by the Plan.

Reclassifications

Certain amounts in the 2009 financial statements have been reclassified to conform with the 2010 presentation. These reclassifications did not affect total net assets available for benefits as previously reported.

Recent Accounting Pronouncements

In September 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-12, Fair Value Measurements and Disclosures (Topic 820): Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), which provides guidance regarding fair value measurement of investments in certain entities that calculate net asset value per share (or its equivalent). This update applies to investments that do not have a readily determinable fair value and are held by an entity that is required to report investment assets at fair value. This update creates a practical expedient to measure the fair value of such investments on the basis of the net asset value per share (or its equivalent) and requires disclosures by major category of investments about the attributes of investments, such as the nature of any restrictions on the investor’s ability to redeem its investments at the measurement date, any unfunded commitments, and the investment strategies of the investees. The Plan’s adoption of this update did not have a material effect on the Plan’s financial statements.

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements (“ASU 2010-06”). ASU 2010-06 amends Subtopic 820-10 to require disclosure of the transfers in and out of Levels 1 and 2. The update also requires additional information for Level 3 related to purchases, sales, issuances and settlements, and requires more detailed disclosure regarding valuation techniques and inputs. ASU 2010-06 as it relates to Levels 1 and 2 was effective for fiscal years and interim periods beginning after December 15, 2009. Requirements relating to Level 3 are effective for fiscal years and interim periods beginning after December 15, 2010. The Plan adopted the currently effective provisions of ASU 2010-06 during January 2010, and its application did not have a material impact on the Plan’s financial statements.

In September 2010, the FASB issued ASU 2010-25, Reporting Loans to Participants by Defined Contribution Pension Plans – a consensus of the FASB Emerging Issues Task Force, clarifying the classification and measurement guidance on participant loans of a defined contribution pension plan (“ASU 2010-25”). ASU 2010-25 requires that participant loans be classified as notes receivable from participants and measured at their unpaid principal balance, plus any accrued but unpaid interest, for fiscal years ending after December 15, 2010 and requires the reclassification to be retrospectively applied to all prior periods presented. The Plan adopted this guidance effective for the Plan year ended December 31, 2010. The adoption had no effect on net assets of the Plan as previously reported.

STILLWATER MINING COMPANY 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

NOTE 2 – INVESTMENT CONTRACT WITH INSURANCE COMPANY

In 2010 and 2009, the Plan held a guaranteed interest account (separately, and as part of blended investment funds), which is a fully benefit-responsive investment contract with MassMutual. MassMutual maintains the contributions in a general account. The guaranteed interest account is credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. The guaranteed interest account issuer is contractually obligated to repay the principal and interest at a specified rate that is guaranteed to the Plan.

As described in Note 1, because the guaranteed interest account is fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to the guaranteed interest account.

There are no reserves against contract value for credit risk of the contract issuer or otherwise. The crediting interest rate is based on a formula agreed upon with the issuer, but it may not be less than 3.00%. Such interest rates are reviewed on a semi-annual basis for resetting. The crediting interest rate was 3.00% as of December 31, 2010 and 2009.

Certain events may limit the ability of the Plan to transact at contract value with the issuer. Such events include the following: (1) amendments to the Plan documents (including complete or partial plan termination or merger with another plan), (2) changes to the Plan’s prohibition on competing investment options or deletion of equity wash provisions, (3) bankruptcy of the Company or other Company events (for example, divestitures or spin-offs of a subsidiary) that cause a significant withdrawal from the Plan, or (4) the failure of the trust to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA. The Plan Administrator does not believe that the occurrence of any such event, which would limit the Plan’s ability to transact at contract value with participants, is probable.

The issuer may terminate the guaranteed interest account with the Plan due to a failure of the Plan to comply with the contractual requirements, failure by the Plan to meet the requirements of the Internal Revenue Code, or a termination or partial termination of the Plan. For termination or partial termination of the Plan, the issuer may terminate at a settlement amount other than the contract value.

NOTE 4 - PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right, under the Plan, to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become 100 percent vested in their Employer contributions.

NOTE 5 – RELATED-PARTY TRANSACTIONS

MassMutual Retirement Services, the record keeper of the Plan, is a division of MassMutual. Certain Plan investments are units of a guaranteed interest account where participant contributions are invested in an investment contract maintained by MassMutual (see note 2). These transactions qualify as exempt party-in-interest transactions.

The Company made matching contributions in Company common stock of $1,141,220 (78,544 shares) during the year ended December 31, 2010. As of December 31, 2010 and 2009, the Plan held $8,546,323 (400,296 shares) and $6,252,883 (659,586 shares), respectively, of common stock; and $441,544 and $191,760, respectively, of interest-bearing cash in a unitized Company stock fund.

As of December 31, 2010 and 2009, the Plan had Employer contributions receivable of $103,386 and $91,448, respectively.

As of December 31, 2010 and 2009, the Plan held notes receivable from participants totaling $1,334,482 and $1,097,278, respectively. Interest income on these loans was $81,681for 2010. Accrued interest receivable totaled $3,228 and $0 as of December 31, 2010 and 2009, respectively.

NOTE 6 - TAX STATUS

The Internal Revenue Service (“IRS”) issued a determination letter dated December 19, 2007, stating that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (“IRC”). The Plan has been amended since the period covered by the determination letter. However, due to the minimal changes in the design of the Plan through subsequent amendments, the Plan Administrator and the Plan’s legal counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been recorded in the accompanying financial statements.

US GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2010 and 2009, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes the Plan is no longer subject to income tax examinations for years prior to 2007.

NOTE 7 – FAIR VALUE MEASUREMENTS

The Plan applies the provisions of ASC 820, Fair Value Measurements and Disclosures, for all financial assets and liabilities and any other assets and liabilities that are recognized or disclosed at fair value on a recurring basis.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2010 AND 2009

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy distinguishes among three levels of inputs that may be utilized when measuring fair value: Level 1 inputs (using quoted prices in active markets for identical assets or liabilities), Level 2 inputs (using external inputs other than Level 1 prices such as quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability) and Level 3 inputs (unobservable inputs supported by little or no market activity and based on internal assumptions used to measure assets and liabilities). The classification of each financial asset or liability within the above hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The table below categorizes the Plan’s investments by level within the fair value hierarchy as of December 31, 2010.
