A reconciliation of total cash costs to cost of sales and other direct production costs and depreciation, depletion and amortization (GAAP) can be found below. Realized prices are calculated by dividing gross revenues for each metal by the payable quantities of each metal included in the concentrate and doré sold during the period. $40 $ $ 2009 20,958 10,989 1.91 ($1.46) 2010 $ $ 2010 (15,435) 10,566 (1.46) $ $ $1.15 $2.24 $1.03 2011 Q1/12 Q2/12 2011 10,934 9,483 1.15 $ $ Q1/12 2,976 1,329 2.24 $ $ Q2/12 1,410 1,365 1.03 $ (15,873) 12,323 (27,617) 112,079 (1,261) – 203 $ 36,621 35,207 (70,776) 164,963 20,254 – 537 $ 20,958 62,837 (80,830) 206,608 310 – 1,596 $ (15,435) 60,011 (92,144) 267,272 3,660 – 630 $ 10,934 47,066 (99,019) 254,372 (4,805) 4,135 (44) $ 2,976 9,661 (17,695) 46,353 1,805 – (149) $ 1,410 9,879 (16,164) 45,352 2,101 – 473 $ 79,854 $ 186,806 $ 211,479 $ 223,994 $ 212,639 $ 42,951 $ 43,051 (1) Cash cost per ounce of silver represents a non-U.S. Generally Accepted Accounting Principles (GAAP) measurement that the Company believes provide management and investors an indication of net cash flow. Management also uses this measurement for the comparative monitoring of performance of mining operations period-to-period from a cash flow perspective. “Total cash cost per ounce” is a measure developed by gold companies in an effort to provide a comparable standard; however, there can be no assurance that our reporting of this non-GAAP measure is similar to that reported by other mining companies. Cost of sales and other direct production costs and depreciation, depletion and amortization, was the most comparable financial measures calculated in accordance with GAAP to total cash costs. (2) Various accidents and other events resulted in temporary suspensions of production at the Lucky Friday mine during 2011. Care-and-maintenance, mine rehabilitation, investigation, and other costs incurred during the suspension periods not related to production have been excluded from total cash costs and the calculation of total cash cost per ounce produced. Operating Properties Greens Creek Admiralty Island, Alaska Silver Reserves – 98 million ounces The 100%-owned Greens Creek underground mine is located in southeast Alaska and produces silver, gold, lead and zinc concentrates. In 2008, Hecla acquired Rio Tinto’s remaining 70% interest in the operation, nearly doubling its overall silver reserves and production. In the second quarter of 2012, Greens Creek produced 1.4 million ounces of silver at a cash cost per ounce of $1.03, net of by-products. Greens Creek is one of the world’s largest high-grade, low-cost silver mines, with more than 200 million ounces produced in the last 20 plus years, during which time it has maintained an 8- to 10-year mine life. Lucky Friday Mullan, Idaho Silver Reserves – 49 million ounces The Lucky Friday silver mine is located in one of the world’s most prolific silver-producing districts: North Idaho’s Silver Valley. It is the deepest operating mine in the United States and has been in commercial production since 1942. Over the past 70 years, more than 150 million ounces of silver have been mined. In 2011, Lucky Friday produced 3.0 million ounces of silver with an average ore grade of 10.69 ounces of silver per ton. During the second quarter of 2012, rehabilitation work on the Silver Shaft was completed past the 4900 level, an important milestone for development work to resume. The resumption of development work, including construction of a bypass drift on the 5900 level, is part of a plan that has been submitted to MSHA. This development plan will prepare the mine for resumption of operations, which is targeted for the first quarter of 2013. Exploration For more than 10 years, Hecla’s strategy has been to build a solid asset base through acquisition and consolidation of district-sized land packages in four world-class mining areas. Exploration in proximity to our operating mines continues to add new resources and convert those to reserves. Significant progress has been made to define new resources at the Star mine in the Silver Valley and at the San Juan Silver property in Creede, CO. A recent, high-grade discovery on the Andrea vein at our San Sebastian property in Mexico will provide a complimentary resource to the Hugh Zone and could re-establish production in Mexico. Four Key Growth Initiatives Lucky Friday #4 Shaft (Mullan, Idaho) Once the Lucky Friday rehabilitation work is complete, construction of the #4 Shaft is expected to resume and will take approximately three years. The #4 Shaft is expected to increase silver production by 60% from approximately 3 million to 5 million ounces per year, mainly due to an expected increase in grade from 10.4 to 14.1 ounces of silver per ton. San Sebastian (Durango, Mexico) Options for accessing the existing resources at the Hugh Zone and a new mine plan have been completed. A preliminary economic analysis is expected to be completed in Q3 2012. A work plan and drill program to define the hydrology of the Andrea area have been completed and preliminary mine designs have begun to compliment potential production from the Hugh Zone. Star (Silver Valley, ID) Underground drilling was initiated in Q4 2011. With completion of the scoping study to evaluate the mineability of the “Upper Country” (above the water table at the 2500 level), a preliminary economic analysis is expected to be completed in Q3 2012. In addition, a dewatering study which is evaluating re-opening the mine below the current water level is also expected to be completed in Q3 2012. Rehabilitation work on the #5 Shaft continues which will provide for secondary surface access. San Juan Silver (Creede, CO) Equity ramp rehabilitation was completed and underground drilling initiated in Q4 2011. Drilling to date has encountered high-grade intercepts. New Bulldog decline portal construction began in Q4 2011. The design of the decline is being finalized with decline development expected to occur in September 2012. A study is under way to evaluate re-opening the Bulldog mine and completion is expected in Q4 2012.
