• Cash and cash equivalents plus highly liquid investments of $439.4 million at quarter end, after funding a $22.4 million increase of recycling working capital and all capital deployed during the third quarter of 2016
• Consolidated net income attributable to common stockholders of $12.6 million or $0.10 per diluted share, compared to a consolidated net loss attributable to common stockholders of $11.9 million or $0.10 per diluted share for the third quarter of 2015, reflecting cost reductions and an increase in sales price per PGM mined ounce to $764 from $693 realized for the third quarter of 2015

Commenting on the third quarter 2016 results, Mick McMullen, the Company’s President and Chief Executive Officer stated, “The third quarter 2016 results demonstrate that Stillwater Mining Company continues to deliver on operational plans and stated objectives. Our efforts to grow the recycling business have been successful as we processed 175,000 ounces of recycled PGMs during the third quarter of 2016, which was a Company record. Mined production and costs were in-line with our expectations. Based on our year-to-date results and future outlook, we remain confident in our ability to achieve the improved full-year guidance targets provided last quarter.

"In addition to the many operational improvements made throughout the organization, our safety performance has continued on a record pace. The safety incidence rate for the third quarter of 2016 decreased by 13.2% compared to the third quarter of 2015. Even more impressive, our safety incidence rate through the first nine months of 2016 is less than the record low rate achieved last year.

"The Company remains focused on Blitz, our primary growth project. The progress on the two critical path items to first production, the 56 East development heading and the 53 East decline is ahead of plan. In addition, considerable engineering work has been updated on the Blitz project. This new work has driven a substantial increase to the scope of the project with relatively minimal additional costs. As a result of the new work performed, the project now incorporates the lower Blitz area. We now anticipate that Blitz will add between 270,000 and 330,000 ounces of mine production annually when fully ramped up by 2021-2022. This is anticipated to be all incremental production for at least the first decade of the Blitz production phase. Costs for the project are expected to increase to approximately $250 million from the previous $205 million estimate, which we consider to be a small escalation given the much expanded scope of the project and the acceleration of the production profile. Additional capital will be required for expansion of the Stillwater Mine concentrator to treat the increased ore tonnage and the related work is currently underway.

Mr. McMullen concluded, “The third quarter provides another data point for the evaluation of the progress we are making at Stillwater. As the business continues to evolve, we have consistently reached our performance targets, while achieving record safety results. I believe we have successfully established a foundation of financial discipline and focus on continuous operational improvement that will allow our shareholders to benefit from the world-class mining and processing assets we possess along with robust PGM market fundamentals. I would like to thank our team for the hard work to achieve the success Stillwater has experienced to date and the continued efforts for future progress."

Total recycled PGM ounces fed to the smelter of 175,000 for the third quarter of 2016 was a Company record and an increase of 8.7% from the third quarter of 2015. The recycling business segment continued to experience a shift from tolled to purchased material in the third quarter of 2016.

PGM recycling revenues totaled $89.6 million for the 2016 third quarter, an increase from $82.0 million in the same period of 2015. The Company's combined average realized price for sales of recycled palladium, platinum and rhodium decreased to $742 per ounce in the third quarter of 2016 compared to $881 per ounce in the third quarter of 2015. Recycling sales volumes for the third quarter of 2016 increased to 117,600 ounces from 88,800 ounces sold in the third quarter of 2015. In conjunction, tolled ounces returned to customers decreased to 49,900 ounces for the third quarter of 2016 from 73,700 ounces in the third quarter of 2015.

PGM recycling costs of metals sold totaled $86.2 million in the third quarter of 2016, an increase from $78.9 million in the third quarter of 2015. A majority of the costs of metals sold from recycling in each period is attributable to the acquisition cost of purchasing recyclable materials for the Company's own account; therefore, the aggregate costs of metals sold from the PGM Recycling segment is driven by the volume and the value of the PGMs in the materials purchased by the Company.

General and administrative costs were $8.7 million in the third quarter of 2016, compared to $8.9 million incurred during the same period of 2015.

Costs of Metals Sold Per PGM Mined Ounce:

(1) Sub-grade tons milled includes reef waste material only. Reef waste material is PGM-bearing mined material below the cutoff grade for proven and probable reserves but with sufficient economic value to justify processing it through the concentrator along with the mined ore. Total tons milled includes ore tons and sub-grade tons only. See “Proven and Probable Ore Reserves – Discussion” in the Company’s 2015 Annual Report on Form 10-K for further information.

(2) Total cash costs include total operating costs plus royalties, insurance and taxes other than income taxes. Total cash costs per PGM mined ounce, net of credits is a non-GAAP financial measure that management uses to monitor and evaluate the efficiency of its mining operations. This measure of cost is not defined under U.S. Generally Accepted Accounting Principles (GAAP). Please see Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures and the accompanying discussion for additional detail.

(3) The concentrate tonnage and grade values are inclusive of periodic re-processing of smelter slag and internal furnace brick PGM bearing materials.

RECONCILIATION OF GAAP FINANCIAL MEASURES TO NON-GAAP FINANCIAL MEASURES

The Company utilizes certain non-GAAP financial measures as indicators in assessing the performance of its mining and processing operations during any period. Because of the processing time required to complete the extraction of finished PGM products, there are typically lags of one to three months between ore production and sale of the finished product. Costs of metals sold - Mine Production, the Company's most directly comparable GAAP financial measure, in any period includes some portion of material mined and processed from prior periods as the process is completed. Consequently, while costs of metals sold - Mine Production (a GAAP measure included in the Company’s Consolidated Statements of Comprehensive Income (Loss)) appropriately reflects the expense associated with the materials sold in any period, the Company has developed certain non-GAAP financial measures to assess the costs associated with its producing and processing activities in a particular period and to compare those costs between periods.

While the Company believes that these non-GAAP financial measures may also be of value to outside readers, both as general indicators of the Company’s mining efficiency from period to period and as insight into how the Company internally measures its operating performance, these non-GAAP financial measures are not standardized across the mining industry and in most cases will not be directly comparable to similar measures that may be provided by other companies. These non-GAAP financial measures are only useful as indicators of relative operational performance in any period, and because they do not take into account the inventory timing differences that are included in costs of metals sold - Mine Production, they cannot meaningfully be used to develop measures of earnings or profitability. A reconciliation of these measures to costs of metals sold - Mine Production, the most directly comparable GAAP financial measure, for each period shown is provided as part of the following tables, and a description of each non-GAAP financial measure is provided below.

Costs of Metals Sold - Mine Production: For the Company as a whole, this measure is equal to total costs of metals sold - Mine Production, as reported in the Company's Consolidated Statements of Comprehensive Income (Loss). For the Stillwater Mine and the East Boulder Mine, the Company segregates the expenses within total costs of metals sold - Mine Production that are directly associated with each of these activities and then allocates the remaining facility costs included in total cost of revenues in proportion to the monthly volumes from each activity. The resulting total costs of metals sold - Mine Production measures for the Stillwater Mine, and the East Boulder Mine are equal, in the aggregate, to total consolidated costs of metals sold - Mine Production as reported in the Company’s Consolidated Statements of Comprehensive Income (Loss).

When divided by the total PGM mined ounces sold in the respective period, Costs of metals sold - Mine Production, measured for each mine or combined, provides an indication of the level of combined cash costs incurred per PGM mined ounce sold in that period. Consequently, Total Combined Cash Costs per PGM mined ounce sold (Non-GAAP) is a general measure of operating efficiency, and is affected both by the level of Total Combined Cash Costs (Non-GAAP) and by the total of PGM mined ounces sold.

Total Combined Cash Costs (Non-GAAP): This non-GAAP financial measure is calculated as total costs of metals sold - Mine Production adjusted for the change in mined inventories to calculate Total Combined Cash Costs before by-product and recycling income credits, (Non-GAAP). From this calculation, the Company deducts by-product and recycling income credits to arrive at Total Combined Cash Costs, net of by-product and recycling income credits. Total Combined Cash Costs is a measure of extraction efficiency. The Company uses this measure as a comparative indication of the cash costs related to production and processing in its mining operations in any period. When divided by PGM ounces produced in the respective period, Total Combined Cash Costs, net of by-products and recycling income credits (Non-GAAP), measured for each mine or combined, provides an indication of the level of combined cash costs incurred per PGM ounce produced in that period.

When divided by the total ore tons milled in the respective period, Total Combined Cash Costs per PGM mined ounce, net of by-product and recycling income credits (Non-GAAP), measured for each mine or combined, provides an indication of the level of combined cash costs incurred per ton milled in that period. Because of variability of ore grade in the Company’s mining operations, production efficiency underground is frequently measured against ore tons produced rather than contained PGM ounces. Because ore tons are first weighed as they are fed into the mill, mill feed is the first point at which production tons are measured precisely. Consequently, Total Combined Cash Costs per Ore Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Combined Cash Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

With respect to 2016 guidance regarding Total Cash Costs per PGM Mined Ounce (net of by-product and recycling credits) and AISC per PGM Mined Ounce, the Company cannot provide a quantitative reconciliation to the most directly comparable GAAP measure without unreasonable effort. However, the Company would expect to calculate these non-GAAP measures in the same manner they were calculated in the reconciliations included in this press release.

Stillwater Mining CompanyAll-In Sustaining Costs (a Non-GAAP Financial Measure)(Unaudited)

All-In Sustaining Costs (Non-GAAP): This non-GAAP financial measure is used as an indicator from period to period of the level of total cash required by the Company to maintain and operate the existing mines, including corporate administrative costs and replacement capital. The measure is calculated beginning with Costs of metal sold - Mine Production, the Company's most directly comparable GAAP financial measure and adding to it the change in mined inventories, and adjusting for the by-product and recycling income credits, domestic corporate general and administrative costs (excluding any depreciation and general and administrative costs of foreign subsidiaries) and that portion of total capital expenditures associated with sustaining the current level of mining operations. Capital expenditures, however, for Blitz and certain other one-time projects are not included in the calculation.

When divided by the total recoverable PGM mined ounces produced in the respective period, All-In Sustaining Costs per PGM Mined Ounce Produced (Non-GAAP) provides an indication of the level of total cash required to maintain and operate the mines per PGM ounce produced in the period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because the objective of PGM mining activity is to extract PGM material, the all-in cash costs per PGM mined ounce to produce PGM material, administer the business and sustain the operating capacity of the mines is a useful measure for comparing overall extraction efficiency between periods. This measure is affected by the total level of spending in the period and by the grade and volume of mined ore produced.

Stillwater Mining CompanyUnderlying Earnings (Loss)(Non-GAAP Financial Measure)(Unaudited)

Underlying Earnings (Loss) (Non-GAAP): This non-GAAP financial measure is considered by the Company to be reflective of the actual income / loss position. This non-GAAP financial measure provides to investors and analysts the ability to understand the results of the continuing operations of the Company relating to the production, processing and sale of PGMs, by excluding certain items that have a disproportionate impact on the results for the reported periods. The measure is calculated beginning with Net income (loss) attributable to common stockholders and adding back impairment charges, one-time event charges and charges infrequent to the Company's continuing operations and the income tax effect of such adjustments. Net loss attributable to noncontrolling interest has been adjusted for the noncontrolling interest's ownership percentage of any applicable impairment charges to which the noncontrolling interest has an ownership. The Company's determination of the components of Underlying earnings (loss) are evaluated periodically and based, in part, on a review of non-GAAP financial measures used by mining industry analysts.

Net income (loss) attributable to common stockholders is reconciled to Adjusted net income (loss) attributable to common stockholders and Underlying earnings (loss) as follows:

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
(In thousands)			2016				2015				2016				2015
Net income (loss) attributable to common stockholders		$	12,599			$	(11,878	)		$	3,452			$	(16,352	)
