Coeur Reports Solid First Quarter Results

Coeur d'Alene Mines Corporation (NYSE:CDE) (TSX:CDM) produced 4.9 million ounces of silver and 43,901 ounces of gold in the first quarter of 2012, which resulted in $204.6 million in sales and $93.8 million in operating cash flow1 during the first quarter of 2012.

First Quarter Highlights:

Net metal sales totaled $204.6 million, 3% higher than the first quarter of 2011.
Silver production totaled 4.9 million ounces, 19% higher than last year's first quarter, and gold production totaled 43,901 ounces.
Cash operating costs1 decreased 25% to $6.29 per silver ounce.
Silver and gold sales totaled 4.3 million ounces and 38,884 ounces, respectively.
Operating cash flow1 increased 4% to $93.8 million.2
General and administrative expenses decreased 38%.
Adjusted earnings1 totaled $41.5 million, or $0.46 per share, an 11% increase over the first quarter of 2011.3
Average realized prices were $32.61 per ounce for silver and $1,702 per ounce for gold, 4% and 24% higher, respectively, than the first quarter of 2011.
Cash, cash equivalents, and short-term investments totaled $153.2 million4 as of March 31.

“The first quarter operating and financial results reflect a solid start to 2012. We are particularly pleased that full production has resumed two months ahead of schedule at Kensington,” said Mitchell J. Krebs, Coeur's President and Chief Executive Officer. “Despite cost pressures throughout our industry, we are proud to have reduced cash operating costs1 per ounce by 25% in the first quarter compared to the same period last year. In addition, we experienced a 38% reduction in our general and administrative costs. Our 2012 production guidance of 18.5 - 20.0 million ounces of silver and 210,000 - 230,000 ounces of gold remains unchanged. With silver and gold prices remaining resilient, we are on-track for a robust second quarter and full-year 2012 performance.”

Mr. Krebs continued, “Palmarejo remains our largest producer and cash flow contributor and posted a strong first quarter. San Bartolomé performed consistently in the first quarter and successfully operated above the 4,400 meter level during most of the quarter. The first quarter marked Rochester's initial three months of operation since resuming active mining in December. We expect production at Rochester to increase each quarter of 2012 as more material is added to the new leach pad. With Kensington now completing several critical projects, the focus will turn to achieving sustainable production levels and reducing costs. With Kensington and Rochester reaching operational consistency, all four of our major long-lived mines are expected to contribute to strong second quarter and full-year performance.”

EBITDA, operating cash flow, adjusted earnings and cash operating costs are non-GAAP measures. Please see tables in the Appendix for reconciliation to U.S. GAAP. Total debt includes short and long-term indebtedness and excludes capital leases and royalty obligations.

Net cash provided by operating activities for the first quarter was $17.0 million compared with $35.8 million for the same time period in 2011. This decrease is primarily the result of a significant tax payment in Bolivia and an increase in inventory due to timing differences between ounces produced and ounces sold.

The Company's U.S. GAAP earnings were negatively impacted by a $23.1 million fair value adjustment, which resulted in net income of $4.0 million, or $0.04 per share, for the first quarter of 2012 compared to net income of $12.5 million, or $0.14 per share, in the first quarter of 2011.

Excludes marketable securities of $20.3 million.

Net metal sales were slightly higher in the first quarter of 2012 than in the first quarter of 2011. This is due largely to higher silver and gold realized prices and increased silver ounces sold, offset by fewer gold ounces sold due to the temporary curtailment of production at Kensington. Silver contributed 68% of the Company's total metal sales during the first quarter of 2012 compared to 56% during the first quarter of 2011.

First quarter production costs of $92.6 million were flat compared to last year's first quarter. General and administrative expenses decreased by $4.6 million, or 38%, from $12.2 million to $7.6 million as compared to the first quarter of 2011. The decrease was primarily caused by lower stock-based compensation expense.

Coeur reports a non-U.S. GAAP metric of adjusted earnings1 as a measure of operating income, which excludes non-cash fair value adjustments, other non-cash adjustments, deferred taxes and discontinued operations. First quarter 2012 adjusted earnings1 were $41.5 million, or $0.46 per share, which was 11% higher than adjusted earnings in the first quarter of 2011 of $37.5 million, or $0.42 per share. On a U.S. GAAP basis, the Company realized net income of $4.0 million, or $0.04 per share, in the first quarter compared with net income of $12.5 million, or $0.14 per share, in the first quarter of 2011. The first quarter net income was impacted by fair value adjustments that decreased net income by $23.1 million. These fair value adjustments are driven primarily by higher gold prices which increased the estimated future liabilities related to a gold royalty obligation at Palmarejo. Net income was also impacted by higher exploration expense and significantly higher income tax expense.

Prior to changes in working capital, Coeur generated operating cash flow1 of $93.8 million during the first quarter of 2012, slightly higher than a year ago. Changes in working capital consumed $76.8 million during the first quarter driven primarily by a significant tax payment in Bolivia and an increase in inventory due to timing differences between ounces produced and ounces sold. After working capital changes, the Company generated cash flow from operations of $17.0 million during the first quarter of 2012 compared to $35.8 million during the first quarter of 2011.

Capital expenditures totaled $31.6 million during the first quarter. Capital expenditures of $10.9 million were incurred at Kensington for the construction of the paste backfill plant, surface construction projects and underground development. San Bartolomé incurred $10.2 million of capital expenditures for tailings facility construction. Palmarejo incurred $7.2 million of capital expenditures most of which was for construction work at its tailings facility.

Cash, cash equivalents, and short-term investments totaled $153.2 million at March 31, 2012 and stood at approximately $175.0 million as of April 30, 2012. Shares outstanding remained steady at 89.9 million.

During the first quarter of 2012, silver production was 4.9 million ounces while gold production was 43,901 ounces, 19% higher and 17% lower, respectively, than a year ago. Lower gold production was expected due to the temporary reduction in mining and processing activities at Kensington. Kensington's production is expected to increase throughout the remainder of 2012 while costs are expected to decline.

Consolidated cash operating costs1 were $6.29 per silver ounce in the first quarter, a significant decrease of 25% from a year ago due primarily to sharply lower costs at Palmarejo. Rochester's costs are expected to continue to decline as production increases throughout the remainder of 2012.

Palmarejo, Mexico - Lower Cash Operating Costs Led to Higher Cash Flow

First quarter silver production increased 44% to 2.5 million ounces compared to the first quarter of 2011. Over the same period, gold production increased 12% to 31,081 ounces.
Significantly higher tons milled and higher recovery rates, especially for silver, led to higher production levels and lower cash operating1 costs per ounce.
First quarter cash operating costs1 per silver ounce were sharply lower at $(2.27) compared to $4.80 a year ago.
Palmarejo is the Company's largest contributor of sales and operating cash flow1, reaching $123.7 million and $79.1 million respectively, in the first quarter. Capital expenditures were $7.2 million.

San Bartolomé, Bolivia - Steady Performance

As anticipated, silver production decreased 7% to 1.6 million ounces due to mining lower grade ore, partially offset by a higher recovery rate, compared to a year ago.
Cash operating costs1 increased 12% compared to last year's first quarter to $10.21 per silver ounce.
San Bartolomé contributed $41.4 million in sales and $20.8 million in operating cash flow1 in the first quarter. Capital expenditures were $10.2 million.

Kensington, Alaska - Full Production Resumes Ahead of Schedule

The Company announced on April 26, 2012 that Kensington is resuming full production ahead of schedule after completing several critical projects, including an underground paste backfill plant, which is currently being commissioned, upgrading the mine's electrical infrastructure, and construction of several new surface facilities. Underground development and infill drilling are advancing ahead of schedule.
Due to the planned temporary reduction in production that began in December 2011, Kensington produced 7,444 ounces of gold at cash operating costs1 of $2,709 per ounce during the first quarter.
The Company's production guidance for 2012 remains unchanged at 82,600 - 86,500 ounces of gold. Approximately two-thirds of Kensington's gold production is expected in the second half of 2012.
The mine contributed $10.4 million in sales while operating cash flow1 was $(7.8) million in the first quarter of 2012. Capital expenditures were $10.9 million.

Rochester, Nevada - First Full Quarter of New Production

Silver production increased 32% in the first quarter to 0.4 million ounces and gold production increased 265% to 5,292 ounces due to initial production from the new leach pad that was constructed in 2011.
Cash operating costs1 were $23.35 per ounce during the first quarter and are expected to decrease steadily as production increases during the remainder of 2012.
The mine contributed $18.8 million in sales and $7.2 million in operating cash flow1 in the first quarter. Capital expenditures were $2.6 million.

Exploration Highlights

The Company plans to spend approximately $40.0 million in exploration during 2012 with approximately 84% of the budget focused on expanding reserves and resources around existing operations. During the first quarter, the Company completed 67,671 meters (222,016 feet) of core and reverse circulation drilling and trenching in its global exploration program.

Palmarejo, Mexico

The Company completed 37,186 meters (122,001 feet) of drilling in the Palmarejo District during the first quarter. Drilling was divided between targets around the Palmarejo mine using both surface and underground drill platforms, specifically the Rosario, Tucson and Chapotillo zones, and at Guadalupe and other targets including La Patria, Independencia and Guerra al Tirano. The bulk of the drilling will take place at Guadalupe and Palmarejo in the second quarter of this year.

Joaquin, Argentina

A total of 14,342 meters (47,021 feet) of drilling was completed in the Santa Cruz Province of southern Argentina in the first quarter. Over 92% of the drilling was completed at the Joaquin joint venture property, with a focus on expanding and increasing the confidence of mineralization at the La Morocha and La Negra deposits and to collect new samples for metallurgy tests. An updated mineral resource estimate is expected to be completed by the end of the second quarter. Upon completion of a feasibility study, the Company's managing and participating interest will increase from 51% to 61%. Subject to certain conditions, the Company has an option to increase its interest further. The Joaquin Project is located approximately 70 kilometers (43 miles) north of the Company's Martha Mine.

Rochester, Nevada

Drilling at Rochester continued at the pace set in the second half of 2011. A total of 12,634 meters (41,450 feet) of reverse circulation drilling were completed on the property. In addition, drilling of surface stockpiles commenced in the quarter.

Kensington, Alaska

Exploration at Kensington consisted of 3,014 meters (9,887 feet) of core drilling in the first quarter. Nearly all of the drilling was devoted to the Raven vein zone which is located approximately 685 meters (2,250 feet) due west of the Kensington ore body. In addition, drilling recommenced on the new Kensington South target which is immediately south of and on trend with the Kensington ore body and has seen little historic exploration. In addition, up to 3 drills were employed to complete 6,211 meters (20,377 feet) of definition drilling to further define the lower part of Zone 10 at Kensington which is expected to form the bulk of mining for the next three years.

2012 Outlook

Production guidance and silver cash operating costs per ounce for 2012 remain unchanged from the Company's February 23, 2012 news release. Coeur expects to produce 18.5 - 20.0 million ounces of silver and 210,000 - 230,000 ounces of gold in 2012. Cash operating costs1 are expected to average $6.50 - $7.50 per ounce of silver (assuming $1,500 per ounce of gold for the by-product credit). Kensington's cash operating costs1 are expected to average approximately $1,150 - $1,250 per ounce of gold for the full year.

The leach cycle at Rochester requires five to ten years to recover gold and silver contained in the ore. The Company estimates the ultimate recovery to be approximately 61% for silver and 92% for gold. However, ultimate recoveries will not be known until leaching operations cease, which is currently estimated for 2017. Current recovery may vary significantly from ultimate recovery.
