Stillwater Mining Company today reported 2012 net income attributable to common stockholders of $55.0 million, or $0.46 per diluted share, on revenues of $800.2 million, compared to net income attributable to common stockholders of $144.3 million, or $1.30 per diluted share, on revenues of $906.0 million in 2011. The Company's mines produced a total of 513,700 ounces of palladium and platinum during 2012, which exceeded the Company's 2012 guidance of 500,000 ounces; and compared to 517,900 ounces produced in 2011. The modest decrease in ounces produced between 2011 and 2012 resulted primarily from normal variability in mining conditions, as well as the array of stopes available for mining from period to period.

Progress continued during 2012 on the Company's PGM development projects. Spending in 2012 was heavily focused on Montana, where the Graham Creek and Blitz projects are under way. The tunnel boring machine, or TBM, drive at Graham Creek had advanced approximately 6,500 feet by the end of 2012, with completion of the full 8,200 feet of development expected during the first half of 2013. The newly acquired TBM at the Blitz project was installed on the east side of the Stillwater Mine during the second half of 2012 and started cutting during December. The machine is expected to develop about 23,000 feet of new TBM drift over the next several years. Also during 2012, the Company identified a new development area within the Stillwater Mine, the Far West project, that will accelerate the opportunity to increase annual mine production at the mine. About 92.6% of 2012 capital spending was committed to the Montana operations. These projects are expected to increase annual PGM production at the Montana operations to about the 600,000 ounce level as they are advanced over the next several years.

Along with these new developments, the Company also more than replaced the reserves it extracted from the existing mines during 2012, increasing proven ore reserves to 3.1 million in-situ ounces at the end of 2012 from 2.6 million ounces at the end of 2011. The year-end 2012 proven ore reserves included 2.4 million ounces of palladium and 0.7 million ounces of platinum. In addition to the growth in proven reserves, the Company also increased its Montana probable reserves of palladium and platinum to 18.4 million ounces from 17.4 million ounces at the end of 2011.

The Company enjoyed excellent safety performance during 2012, achieving the lowest incidence rate of reportable injuries for any year in its history. The Company began adopting the National Mining Association-sponsored CoreSafety program during 2012, layering the modules that this new program provides over its existing framework of safety practices.

Sales and earnings in 2012 were principally affected by lower PGM prices and higher costs. Average prices realized for mined ounces of palladium were $641 in 2012, compared to $739 in 2011, and for platinum were $1,551 in 2012 compared to $1,705 in 2011. Of the $800.2 million of revenues recorded in 2012, $455.4 million was attributable to sales from mine production and $344.8 million was generated by the Company's recycling activities. Comparable revenues for 2011 of $906.0 million included $528.0 million from mine production, $376.8 million from recycling, and $1.1 million from the resale of purchased metal.

Total cash costs per ounce of palladium and platinum produced (total cash cost is a non-GAAP measure of extraction efficiency described in more detail below) averaged $484 per ounce in 2012, which was better than the Company's guidance of $500 per ounce for the year, due primarily to higher-than-planned ounces produced in 2012. The 2012 total cash cost per ounce was approximately 15% higher than the $420 per ounce experienced in 2011. These higher costs were essentially in line with the 2012 mining plan and included the anticipated effect of increasing infrastructure and miner travel times as distances from mine access increase ("receding face"), contractual wage increases, an aggressive new-miner training program (both to support current production levels and to prepare for the Company's three Montana-based PGM growth initiatives), and some catch-up spending (in terms of infrastructure/administrative support) following the sharp cutbacks in 2009 and 2010.

Total revenues for the fourth quarter of 2012 were $203.4 million, down from $259.7 million in the 2011 fourth quarter. Average prices realized in the fourth quarter of 2012 for mined ounces of palladium were $647, compared to $644 in 2011 and for platinum were $1,594 in the fourth quarter of 2012 compared to $1,518 in 2011. For the 2012 fourth quarter, consolidated net income attributable to common stockholders was $16.9 million, or $0.13 per diluted share. Net income attributable to common stockholders reported for the fourth quarter of 2011 was $24.7 million, or $0.21 per diluted share on revenues of $259.7 million. The fourth quarter 2012 results reflect lower PGM sales volumes and higher consolidated total cash costs than in last year's fourth quarter and include a $2.2 million foreign currency transaction gain and exploration expenses of $1.2 million.

The Company's recycling business earned $10.5 million in 2012, down from $18.8 million in 2011. The Company's total volume of recycling material processed was 445,200 combined ounces of palladium, platinum and rhodium compared with 486,700 combined ounces in 2011. Fourth quarter 2012 recycling earnings were $2.5 million, down from $8.1 million in the fourth quarter of 2011 on lower sales volumes and lower realized prices during 2012.

Commenting on the Company's 2012 annual results, Frank McAllister, the Company's Chairman and Chief Executive Officer, observed, "The Company's mining and processing operations performed exceptionally well during the year. Combined safety performance in 2012 at our two Montana mines was the best in the Company's history. Production has been steady and better than planned. While palladium and platinum prices on average were substantially lower in 2012 than in the prior year, resulting in lower earnings, PGM market fundamentals currently are robust, particularly with respect to palladium.

"With growing PGM demand and constrained supply, in our view prices for both palladium and platinum are likely to increase from their current strong levels. Importantly, with the sharp reduction in Russian government exports of palladium, and the persistent growth in demand from the auto industry for catalytic converters, the traditional steep discount in the price of palladium relative to platinum has narrowed substantially. From 2003 through mid-2010, the price of palladium typically ranged between 20% and 25% of the price of platinum; since the middle of 2010 it has averaged between 40% and 45% of the platinum price. The Company's mines produce on average about 3.4 times as much palladium as platinum, so this pricing realignment has and will benefit the Company's earnings and the Company's relative cost position to that of other PGM producers.

"With respect to our Montana PGM development projects, we continue to actively pursue all three (Graham Creek, Far West and Blitz), and anticipate these three projects will result in a 20% increase in our annual production rate over the next several years. The Graham Creek project is now well advanced, expanding to the west in areas adjacent to our existing operations at the East Boulder Mine. Through the end of 2012, the TBM has completed about 6,500 feet of new development to the west, out of its total targeted footage of 8,200 feet. The TBM drive should be finished in the first half of 2013, after which we will begin developing two new ventilation shafts to the surface there. These shafts should be completed in early 2015. Once completed, Graham Creek is projected to increase East Boulder Mine production by approximately 30,000 ounces of palladium and platinum per year. We estimate the total cost of the Graham Creek project will be approximately $13 million, of which $3.5 million has been incurred through the end of 2012.

"We also recently announced an opportunity to accelerate some key development in an area located within the existing boundary of the Stillwater Mine. This area, known as the Far West, is situated below the Upper West section of the Stillwater Mine, which has been actively mined for many years. Far West is an area that has been reflected in our long-term mine plans and as our underground development headings have now reached that area, ore grades there appear to be a bit better than are typically found in the Upper West section. Because we expect to have access to production from the Blitz area in the future to help maintain Stillwater's longer-term PGM production, we believe it makes sense to accelerate development at Far West now, which should allow us to increase annual production at the Stillwater Mine ahead of the timetable for Blitz. Developing this project will require pulling forward from future years approximately $28 million of capital spending into the next three years, including approximately $8.6 million into 2013. Once operational this area is projected to add production of approximately 20,000 PGM ounces in 2016 and about 45,000 PGM ounces per year thereafter.

"As reported previously, a newly acquired TBM is now in operation at the Blitz project. This new TBM is located inside the 5000 East portal at the Stillwater Mine and ultimately will drive a 23,000 foot access drift towards the east along the J-M Reef. Simultaneously, a mining team is driving a parallel tunnel about 600 feet above the TBM, using conventional drill and blast methods. Both tunnels eventually will intersect a decline to be developed from a new surface portal located about four miles to the east of the existing Stillwater Mine surface facilities that will provide ventilation and emergency egress for the Blitz area. The Blitz project, which provides a backbone for our planned future operations to the east of the Stillwater Mine, is targeted for completion in late 2017 or 2018. While it is still too early to estimate future annual production from the Blitz area with any precision, we preliminarily expect Blitz production to replace depleting production in the off-shaft area of the Stillwater Mine, as well as to contribute approximately 25,000 ounces of incremental PGM production on an annual basis. Total cost to complete the Blitz project currently is estimated at about $209 million, of which about $35.1 million has been incurred through the end of 2012."

Turning to the Company's Marathon PGM-copper project in Canada, Mr. McAllister commented, "Our efforts at Marathon are focused primarily on two fronts right now -- advancing the joint federal/provincial environmental review of the Marathon project, and completing the definitive engineering study now underway. Marathon remains our key palladium priority outside of Montana and we expect completion of an updated engineering study in the third quarter of 2013."

Regarding the Company's Altar copper-gold exploration project in northwestern Argentina, Mr. McAllister noted, "Although the Altar exploration and related support expenditures were budgeted at about $25 million for 2012, in the end we spent about $17.5 million (including administrative expenses). Altar continues to provide a low-cost insurance option going forward, with significant upside resource potential as last year's successful drilling demonstrated. We will continue to employ a highly disciplined exploration program there to determine prudently the extent and quality of the Altar system without diverting resources from our core PGM commitment."

"Importantly, with the recent financing proceeds in hand, we now have extremely strong balance sheet liquidity, which in conjunction with our expected cash flows from operations, should enable us to aggressively pursue our PGM growth initiatives at a time when many of our industry peers are facing significant operational and financial challenges."

Commenting on costs Mr. McAllister observed, "Our advance guidance for 2013 total cash cost is $560 per ounce at a production level of 500,000 ounces of palladium and platinum, which would represent about a 16% year-on-year increase over the $484 per ounce averaged in 2012. I noted earlier that the mines' 2012 average total cash cost of $484 per ounce (a non-GAAP measure) was about 15% higher than the $420 per ounce experienced in 2011.

"These back-to-back annual increases in total cash cost per ounce of 15% in 2012 and almost 16% in 2013 are in line with our planning. As already noted, there are a number of cost pressures inherent in our business that all underground mining companies share. Our mining costs are driven in part by the ongoing effect of ever-expanding operations underground ("receding face"); at times by lower cut-off grades made possible by higher prices; by contractual wage increases; and underlying inflation in materials costs. These higher costs also in part reflect the investment in our new-miner training program necessary both to support current production levels and to prepare for the Company's three Montana-based PGM growth initiatives.

"It is useful to take a longer view of the Company's cost growth. If the Company's developed state is sufficiently robust, then during temporary down cycles in metals prices, some capital and operating costs can temporarily be scaled back in order to conserve cash. Ultimately, this deferred spending must be caught back up or production rates will suffer. To some extent, capital and operating expenditures during 2012 and 2013 include additional maintenance and infrastructure spending to compensate for cutbacks made to conserve cash during the economic downturn in 2009 and 2010. The cumulative annual growth rate in total cash costs per mined ounce for the five years from 2008 projected through 2013, taking into account the economic downturn and subsequent recovery, averages about 7% per year -- about what would be expected assuming low underlying inflation and taking the receding face issue into account. Other analyses of relative costs suggest that the Company's cost structure has become increasingly more competitive within the PGM industry over the past several years as competitor costs have escalated sharply. A 7% annual growth rate in cash cost per ounce over that period also compares very favorably to the much higher cost growth many other companies in the mining industry experienced over that period.

"Specifically, our plans include miner training programs at the two Montana mines which involve hiring on the order of 50 new miners each year who are not expected to reach their full productive potential as miners for three to five years. These new miners, once fully trained, are intended to step into future mining roles as employees retire or otherwise leave the Company, and also represent the investment in manpower necessary to support the production growth we are envisioning from our Montana operations over the next several years. In our view, making this investment now will pay for itself many times over as we realize value on our advancing growth projects. With regard to manpower, the total number of Montana employees has increased to 1,632 at the end of 2012, up from 1,522 at the end of 2011, reflecting hiring of additional qualified miners, miner trainees and mine support personnel.

"Regarding the growth in costs each year is to be expected at underground mines. Each year, mining continually gets deeper and travel ways extend further, increasing the time and resources needed to transport people and materials to and from the mining faces. Our mine planning models suggest that this effect alone can increase costs by as much as 5% to 6% per year. In this regard, one early advantage of the Blitz project as it comes into production is that its initial mining areas should be located much closer to the mine portals."

Commenting on the Company's downstream processing facilities, Mr. McAllister added, "At the smelter in Columbus, Montana we now have two electric furnaces in operation. After we commissioned our new No. 2 smelting furnace in May of 2009, we stripped the brick out of the old No. 1 furnace in anticipation of refurbishing it to become a slag cleaning circuit. During 2011, we rebricked the old furnace and completed the necessary engineering to allow us to transfer slag directly from our primary No. 2 furnace into the slag cleaning bath in the No. 1 furnace. Initial construction of the slag cleaning circuit was completed in late 2012, although we have made a few minor modifications subsequently. Later this year, we intend to temporarily shut down the No. 2 furnace for rebricking, operating the refurbished No. 1 furnace as primary until furnace No. 2 is ready to restart. We estimate this refurbishing will probably take four to five weeks. An additional benefit of operating a second furnace is we don't have to stockpile concentrates and recycle materials while the furnace is being refurbished.

"Finally, we would like to acknowledge and welcome Mr. George Bee as a new director recently appointed to our Company's board. George brings with him an extensive breadth of worldwide mining and management experience. We are very pleased to have him join the Board, and we look forward to the benefit of his perspective on our Company's activities."

Quarterly Results
Production during the fourth quarter of 2012 totaled 132,500 ounces of palladium and platinum, an increase of 16.2% from the 114,000 ounces produced in the fourth quarter of 2011 and a 4.3% increase from the 127,000 ounces produced during the third quarter of 2012.

Capital Outlay

The Company's 2012 capital outlay totaled $116.6 million, less than the Company's original 2012 guidance of $135 million but an increase over 2011 outlay of $104.1 million. The increased capital outlay was driven primarily by the Blitz and Graham Creek development projects in Montana and by engineering and environmental work at the Company's Marathon PGM-copper project in Canada. Exploration expense totaled $15.0 million in 2012, up from $2.5 million in 2011. The increase in exploration expense reflected drilling activity during the first half of 2012 at the Company's Altar project in Argentina. The table below provides detail on capital spending by project in 2012 and 2011.

(1) Capital outlay excludes approximately $6.3 million of anticipated non-cash capitalized interest in 2013. Capital outlay in 2012 excludes $0.9 million of non-cash capitalized interest. No non-cash capitalized interest was recorded in 2011.

The Company's planned 2013 capital spending is expected to total about $172.8 million, reflecting substantial 2013 investment in the Company's expansion projects. Spending at the Stillwater Mine will include accelerated development in the Far West area of the mine, which is projected to allow for increased production at Stillwater beginning in 2016. Other Stillwater Mine spending will include expansion of the Kiruna electric haulage deeper into the mine and purchase of some additional ore haulage equipment necessary as distances underground increase. Expenditures at the Blitz project include development along two parallel drifts extending to the east from the existing Stillwater Mine infrastructure, while Graham Creek finishes up its TBM drift to the west of the East Boulder Mine in early 2013 and begins development of two ventilation raises to surface. Engineering and environmental review continue at the Marathon project in an effort to finalize the design criteria and project economics.

The Company has evaluated its 2013 capital and exploratory budgets and has concluded that, at recent metals prices, its available liquidity and cash flow from operations are adequate to support its capital and exploratory spending plans for 2013. However, the Company also maintains significant discretion in its spending plans and can adjust the allocation and, to a reasonable extent, the timing of spending as necessary. The Company currently has several capital intensive development projects in its pipeline. While all of these projects are considered important to the organization, the Company has prioritized these efforts during its budgeting process. The Company's first priority is clearly to sustain the developed state of its current mining operations, including the Graham Creek project, which is essentially an extension of the East Boulder Mine and is relatively low cost. The Blitz project, which is designed to extend underground access and ultimately to maintain and grow annual production at the Stillwater Mine, has a less critical timeline at this point, although its potential to grow value is significant.

Review of Investor Guidance for 2013

The Company's Montana mining operations as currently configured, function well at a production rate of approximately 500,000 combined ounces of palladium and platinum per year. Mine plans for 2013 once again have been structured to achieve that level of production. It is anticipated that total cash cost per ounce (a non-GAAP measure) for the two Montana mines will average approximately $560 in 2013, 15.7% higher than the $484 per ounce averaged in 2012. The projected year-on-year increase in total cash costs per ounce reflects expected 2013 general inflation in supply costs, the effect of the underground receding face, contractual wage increases, continued growth in the Company's new-miner training program, and slightly lower 2013 planned mine production.

Capital expenditures are budgeted to total approximately $172.8 million for 2013, up from $116.6 million in 2012. The increase is attributable primarily to additional capital requirements at the Marathon project, along with the acceleration of the Far West development area within the Stillwater Mine. Development spending plans established for 2013 are comprised of approximately $16.5 million for the Blitz project, $4.7 million for Graham Creek and $21.9 million for the Marathon PGM-copper project.

Cash Flow and Liquidity

At December 31, 2012, the Company's total available cash and cash equivalents was $379.7 million, compared to $109.1 million at December 31, 2011. If highly liquid short-term investments are included with available cash, the Company's balance sheet liquidity totaled $641.7 million at December 31, 2012, an increase from $158.6 million at December 31, 2011. Most of the net increase in cash during 2012 is attributable to the sale of $396.75 million of convertible debentures in October. Of the Company's cash balance at the end of 2012, $43.4 million is dedicated to the Marathon project (and other related properties) and is unavailable for other corporate purposes. Net working capital -- comprised of total current assets (including available cash and short-term investments), less current liabilities -- increased to $606.0 million at December 31, 2012, from $251.6 million at year end 2011. The December 31, 2012 amount includes $166.5 million reclassified as the current portion of long-term debt, reflecting the Company's existing 1.875% convertible debentures that are expected to be redeemed in cash by their holders on March 15, 2013.

Net cash provided by operating activities (which includes changes in working capital) in the fourth quarter of 2012 totaled $3.8 million, compared to $91.8 million of cash provided in the fourth quarter of 2011. Capital expenditures (adjusted to include incurred but unpaid obligations at the end of each period) were $30.6 million in the fourth quarter of 2012, a little higher than the $27.0 million reported for the fourth quarter of 2011. For the full year 2012, net cash provided by operating activities totaled $103.9 million, down from $219.7 million for the year 2011, reflecting lower PGM prices and higher cash costs in 2012. Capital expenditures for the full year 2012 totaled $117.1 million (including capitalized interest and obligations incurred but unpaid at year end), compared to $104.1 million for the year 2011.

Outstanding debt at December 31, 2012, was $461.1 million, up from $196.0 million at December 31, 2011. The Company's debt includes $424.7 million outstanding in the form of convertible debentures, $29.6 million of exempt facility revenue bonds due in 2020, a capital lease of $6.5 million and $0.3 million for a small installment land purchase. On October 17, 2012, the Company completed the issuance and sale of $396.75 million of 1.75% convertible senior unsecured notes due in 2032. In accordance with U.S. generally accepted accounting principles, the value of these newly-issued convertible debentures, which can be settled upon conversion in any combination of cash and common shares at the Company's discretion, has been bifurcated into a $255.2 million long-term debt component and a $141.5 million equity component that reflects the value of the embedded conversion feature. The Company intends to use the net proceeds from this offering to repay amounts that may come due under the Company's outstanding 1.875% convertible debentures in March 2013, and for general corporate purposes.

1.  Sub-grade tons milled includes reef waste material only. Total tons
    milled includes ore tons and sub-grade tons only. See "Proven and
    Probable Ore Reserves - Discussion" in the Company's 2011 Annual Report
    on Form 10-K for further information.
2.  Total operating costs include costs of mining, processing and
    administrative expenses at the mine site (including mine site overhead
    and credits for metals produced other than palladium and platinum from
    mine production). Total cash costs include total operating costs plus
    royalties, insurance and taxes other than income taxes. Total production
    costs include total cash costs plus asset retirement costs and
    depreciation and amortization. Income taxes, corporate general and
    administrative expenses, asset impairment write-downs, gain or loss on
    disposal of property, plant and equipment, restructuring costs and
    interest income and expense are not included in total operating costs,
    total cash costs or total production costs. Operating costs per ton,
    operating costs per ounce, cash costs per ton, cash costs per ounce,
    production costs per ton and production costs per ounce are non-GAAP
    measurements that management uses to monitor and evaluate the efficiency
    of its mining operations. These measures of cost are not defined under
    U.S. Generally Accepted Accounting Principles (GAAP). Please see
    "Reconciliation of Non-GAAP Measures to Costs of Revenues" and the
    accompanying discussion for additional detail.

Reconciliation of Non-GAAP Measures to Costs of Revenues

The Company utilizes certain non-GAAP 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. Sales in any period include some portion of material mined and processed from prior periods as the revenue recognition process is completed. Consequently, while costs of revenues (a GAAP measure included in the Company's Consolidated Statement of Operations and Comprehensive Income) appropriately reflects the expense associated with the materials sold in any period, the Company has developed certain non-GAAP 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 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 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 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 revenues, they cannot meaningfully be used to develop measures of earnings or profitability. A reconciliation of these measures to costs of revenues for each period shown is provided as part of the following tables, and a description of each non-GAAP measure is provided below.

Total Costs of Revenues: For the Company as a whole, this measure is equal to total costs of revenues, as reported in the Consolidated Statement of Operations and Comprehensive Income. For the Stillwater Mine, the East Boulder Mine, and other PGM activities, the Company segregates the expenses within total costs of revenues 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 revenues measures for Stillwater Mine, East Boulder Mine and other PGM activities are equal in total to total costs of revenues as reported in the Company's Consolidated Statement of Operations and Comprehensive Income.

Total Production Costs (Non-GAAP): Calculated as total costs of revenues (for each mine or combined) adjusted to exclude gains or losses on asset dispositions, costs and profit from recycling activities, revenues from the sale of mined by-products and timing differences resulting from changes in product inventories. This non-GAAP measure provides a comparative measure of the total costs incurred in association with production and processing activities in a period, and may be compared to prior periods or between the Company's mines.

When divided by the total tons milled in the respective period, Total Production Cost per Ton Milled (Non-GAAP) -- measured for each mine or combined -- provides an indication of the cost 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 actually weighed as they are fed into the mill, mill feed is the first point at which production tons are measured precisely. Consequently, Total Production Cost per Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Production Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

When divided by the total recoverable PGM ounces from production in the respective period, Total Production Cost per Ounce (Non-GAAP) -- measured for each mine or combined --- provides an indication of the cost per ounce produced in that period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because extracting PGM material is ultimately the objective of mining, the cost per ounce of extracting and processing PGM ounces in a period is a useful measure for comparing extraction efficiency between periods and between the Company's mines. Consequently, Total Production Cost per Ounce (Non-GAAP) in any period is a general measure of extraction efficiency, and is affected by the level of Total Production Costs (Non-GAAP), by the grade of the ore produced and by the volume of ore produced in the period.

Total Cash Costs (Non-GAAP): This non-GAAP measure is calculated by excluding the depreciation and amortization and asset retirement costs from Total Production Costs (Non-GAAP) for each mine or combined. The Company uses this measure as a comparative indication of the cash costs related to production and processing in any period.

When divided by the total tons milled in the respective period, Total Cash Cost per Ton Milled (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of 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 Cash Cost per Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Cash Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

When divided by the total recoverable PGM ounces from production in the respective period, Total Cash Cost per Ounce (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of cash costs incurred per PGM ounce produced in that period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because ultimately extracting PGM material is the objective of mining, the cash cost per ounce of extracting and processing PGM ounces in a period is a useful measure for comparing extraction efficiency between periods and between the Company's mines. Consequently, Total Cash Cost per Ounce (Non-GAAP) in any period is a general measure of extraction efficiency, and is affected by the level of Total Cash Costs (Non-GAAP), by the grade of the ore produced and by the volume of ore produced in the period.

Total Operating Costs (Non-GAAP): This non-GAAP measure is derived from Total Cash Costs (Non-GAAP) for each mine or combined by excluding royalty, tax and insurance expenses from Total Cash Costs (Non-GAAP). Royalties, taxes and insurance costs are contractual or governmental obligations outside of the control of the Company's mining operations, and in the case of royalties and most taxes, are driven more by the level of sales realizations rather than by operating efficiency. Consequently, Total Operating Costs (Non-GAAP) is a useful indicator of the level of production and processing costs incurred in a period that are under the control of mining operations.

When divided by the total tons milled in the respective period, Total Operating Cost per Ton Milled (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of controllable 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 actually weighed as they are fed into the mill, mill feed is the first point at which production tons are measured precisely. Consequently, Total Operating Cost per Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Operating Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

When divided by the total recoverable PGM ounces from production in the respective period, Total Operating Cost per Ounce (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of controllable cash costs incurred per PGM ounce produced in that period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because ultimately extracting PGM material is the objective of mining, the cost per ounce of extracting and processing PGM ounces in a period is a useful measure for comparing extraction efficiency between periods and between the Company's mines. Consequently, Total Operating Cost per Ounce (Non-GAAP) in any period is a general measure of extraction efficiency, and is affected by the level of Total Operating Costs (Non-GAAP), by the grade of the ore produced and by the volume of ore produced in the period.
