Coeur Reports First Quarter 2013 Results

Palmarejo rebounds

Timing of metal sales versus production impacts financial results

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Coeur d'Alene Mines Corporation (CDE) (the Company or Coeur) (NYSE: CDE) (TSX: CDM) reported metal sales of $171.8 million, operating cash flow1of $58.7 million, and capital expenditures of $12.8 million during the first quarter 2013.

The Company produced 3.8 million ounces of silver and 56,913 ounces of gold during the first quarter 2013. Silver and gold production at Palmarejo increased 6% and 15%, respectively, compared to the prior quarter while costs declined significantly from $7.55 per silver ounce1 to $2.20 per silver ounce1. Companywide cash operating costs were $8.73 per silver ounce1and were $1,055 per gold ounce at the Company'sKensingtongold mine during the first quarter.

The Company reaffirmed its 2013 full-year production guidance of 18.0-19.5 million ounces of silver and 250,000-265,000 ounces of gold. Coeur's full-year cash operating cost1guidance is being revised to $9.50 - $10.50 per silver ounce (compared to previous guidance of $8.00 - $9.00 per ounce) to reflect an assumed $1,500 per ounce gold price during the remainder of the year for by-product credits (compared to $1,650 per ounce used in prior guidance).Kensington'scash operating costs per gold ounce1guidance remains unchanged at $900 - $950 for 2013.

During the first quarter, the Company successfully completed a $300 million senior unsecured notes financing, redeemed $43.3 million of the outstanding $48.7 million of 3.25% convertible debentures and closed the approximately $280 million acquisition ofOrko Silver Corp., which adds the La Preciosa silver project inMexicoto the Company's growth profile. The Company announced the relocation of its corporate headquarters toChicagoand that, subject to shareholder approval, the Company will reincorporate toDelawareand change its name toCoeur Mining, Inc.promptly following the Annual Meeting of Shareholders on May 14, 2013. In addition, Coeur repurchased 655,474 shares of its own stock for $12.6 million during the first quarter 2013. The Company has now completed $32.5 million of its $100 million share repurchase program authorized by the Board of Directors in June of 2012.

First Quarter 2013 Highlights

• Silver production totaled 3.8 million ounces, a 22% decrease from the first quarter 2012 and level with fourth quarter 2012.
• Gold production totaled 56,913 ounces, up 30% from the first quarter 2012 and down 6% from fourth quarter 2012.
• Metal (MTLK) sold of 3.1 million silver ounces and 51,926 gold ounces resulted in lower metal sales during the quarter as a result of quarter-end timing.
• Average realized prices were $30.30 per silver ounce and $1,630 per gold ounce, down 7% for silver and 4% for gold from the first quarter 2012, and 7% lower for silver and 5% for gold compared with the fourth quarter 2012.
• Cash operating costs for silveraveraged $8.73 per silver ounce1 compared with $8.97 per silver ounce1 in the fourth quarter 2012. Kensington's cash operating costs averaged $1,055 per gold ounce1 compared with $1,065 per gold ounce1 in the fourth quarter 2012.
• Adjusted earnings1were $6.8 million, or $0.08 per share, compared with $41.5 million, or $0.46 per share, in the first quarter 2012. Net income for the first quarter 2013 was $12.3 million, or $0.14 per share, compared with net income of $4.0 million, or $0.04 per share, in the first quarter 2012.
• Cash, cash equivalents and short-term investments were $332.8 million at March 31, 2013, compared with $153.2 million a year ago. On April 16, 2013, $99.1 million was used as part of the consideration to acquire Orko Silver (OKOFF.PK).
• Subsequent to the issuance of 11.6 million common shares toOrko Silvershareholders on April 16, 2013, Coeur has 101.5 million in total shares outstanding at May 8, 2013.

Mitchell J. Krebs, Coeur's President and Chief Executive Officer, said, Through the first four months of 2013, Coeur has been actively pursuing its strategic objectives of (i) creating a foundation for improved operational consistency throughout the remainder of the year and beyond; (ii) reducing costs and improving the efficiency at our existing mines; (iii) reinvesting in our existing assets to increase production and cash flow; (iv) repurchasing shares, which we feel represent compelling long-term value, especially at current levels; (v) pursuing opportunities to acquire and sell assets in order to create long-term value for our shareholders; and (vi) advancing our capital projects that are critical to the Company's continued growth and sustainability.

We are pleased that silver and gold production at Palmarejo rebounded at materially lower costs per ounce1 than the last quarter of 2012. Although production levels at our Palmarejo operation had a slow start to the year due to lower than planned grades, both March and April were strong months and we remain confident in our 2013 guidance for this important asset.Rochesteralso started slow due to extreme winter weather inNevadaand we are pursuing alternatives to catch up production that was not realized during January and February. We remain enthusiastic about the expansion opportunities atRochester, which we believe can make this long-running operation our largest cash flow generator in the next five years. Our San Bartolomé silver mine inBoliviacontinues to exceed plan levels despite mining lower grade material. TheKensingtongold mine inAlaskais now demonstrating its ability to operate more consistently as planned. We expect production fromKensingtonto increase during the second half of the year due to higher grades.

Since completion of the Orko Silver transaction, we have been actively building a project development team and commissioned a preliminary economic assessment (PEA) of the La Preciosa project by M3 Engineering, the results of which we expect to have by June 30th. We believe La Preciosa will become another long-life, cornerstone asset for the Company and will generate a return on investment in excess of the Company's cost of capital.

Table 1: Financial Highlights (Unaudited)

First quarter net metal sales were $171.8 million compared with $204.6 million in the first quarter of 2012 due to lower metal prices and fewer silver ounces sold, which was partially offset by more gold ounces sold.

Silver contributed 53% of the Company's total metal sales in the first quarter 2013 compared with 68% in the first quarter 2012 due to increased gold production at the Company'sKensingtonandRochestermines.

Consolidated production costs were $88.8 million in the first quarter 2013, which was down 4% compared to last year's first quarter and 17% lower than the fourth quarter 2012. On a per ton milled basis, production costs were 16% lower compared with the first quarter 2012. Production costs at each of the Company's operations are on plan. Unit costs are expected to decline over the remainder of 2013 with the expected ramp up in production. Cash operating costs per silver ounce1were higher compared with the first quarter 2012 due to lower production. Compared to the fourth quarter, costs per silver ounce1 declined 3%.

Prior to changes in working capital, Coeur generated $58.7 million in operating cash flow1in the first quarter 2013 compared with $93.8 million in the first quarter 2012. Including changes in working capital, net cash from operating activities was $12.9 million compared with $17.0 million in the first quarter 2012. Inventories increased $20.5 million during the first quarter due to timing of metal sales, which were realized in April 2013. In addition, accounts payable and accrued liabilities declined $27.0 million during the quarter due mostly to an annual tax payment toBolivia.

On a U.S. GAAP basis, the Company realized net income of $12.3 million, or $0.14 per share, in the first quarter 2013 compared with net income of $4.0 million, or $0.04 per share, in the first quarter 2012. Net income for the first quarter 2013 included a non-cash fair market value adjustment of positive $17.8 million. The fair market value adjustment in the first quarter 2012 was negative $23.1 million. Fair value adjustments are driven primarily by lower or higher gold prices, which decrease or increase, respectively, the estimated future liabilities related to a gold royalty obligation at Palmarejo.

Coeur reports a non-U.S. GAAP metric of adjusted earnings1as a measure of operating income, which excludes non-cash fair value adjustments, other non-cash adjustments, deferred taxes and discontinued operations. Adjusted earnings1were $6.8 million, or $0.08 per share, in the first quarter 2013, compared with $41.5 million, or $0.46 per share, in the first quarter 2012. Adjusted earnings were lower due to a $32.8 million decline in metal sales and a $6.4 million increase in general and administrative, pre-development, care and maintenance, and other expenses.

Capital expenditures were $12.8 million in the first quarter 2013, a 59% decrease from the first quarter 2012. Capital expenditures were primarily related to Palmarejo's capitalized exploration drilling, underground development and development of the Guadalupe satellite operation located near the Palmarejo mine, leach pad and crusher expansion atRochester, and exploration drilling and underground development atKensington.

Cash, cash equivalents and short-term investments were $332.8 million at March 31, 2013. On January 29, 2013, the Company realized net proceeds of $290.8 million from the sale of $300.0 million in aggregate principal amount of 7.875% Senior Notes due in 2021. On April 16, 2013, $99.1 million (CAD $100.0 million) was used in connection with the acquisition ofOrko Silver Corp.The Company's $100 million revolving credit facility remains undrawn.

Coeur andXDM Royalty Corp.(XDM) have terminated the previously-announced letter of intent whereby Coeur announced its intent to sell its interest in the silver production and reserves from the Endeavor mine in Australia and the royalty from the Cerro Bayo gold and silver mine in southern Chile.Mr. Krebssaid, The proposed transaction with XDM provided Coeur with an opportunity to monetize certain non-core assets. Unfortunately, a severe dislocation in metals markets has disrupted the transaction. Both parties remain committed to continuing discussions to possibly reach a revised agreement.

Table 3: Operational Highlights: Cash Operating Costs Per Ounce1

Palmarejo,Mexico- Rebounding with Expected Improved Quarters to Come

• Palmarejo produced 1.65 million ounces of silver and 22,965 ounces of gold at cash operating costs of $2.20 per silver ounce1 for the first quarter. In the fourth quarter of 2012, Palmarejo produced 1.55 million ounces of silver and 19,998 ounces of gold at cash operating costs of $7.55 per silver ounce1.
• Palmarejo's underground and open pit mining rates improved and stabilized during the first quarter compared to the last four months of 2012. Silver and gold ore grades from both the open pit and from underground operations are generally expected to continue increasing during the remainder of the year as they have in March and April.
• Palmarejo's mine rescue team earned first place and the first aid response team second place in their respective competitions at theNorthern Mexico Mine RescueandFirst Aid Competitionheld in mid-March 2013. The Company's subsidiary Coeur Mexicana was also recognized by theMexican Centre for Philanthropywith the Socially Responsible Business Distinction Award for the exemplary Palmarejo operations for the fifth year in a row.
• Sales and operating cash flow1totaled $57.4 million and $31.5 million, respectively, in the first quarter 2013.
• Capital expenditures were $5.3 million during this quarter.

San Bartolomé,Bolivia- Stable Production and Mill Expansion On-Track

• San Bartolomé produced 1.4 million ounces of silver at cash operating costs of $13.27 per silver ounce1. In the fourth quarter of 2012, San Bartolomé produced 1.3 million ounces of silver at cash operating costs of $13.97 per silver ounce1.
• The Company is in the process of increasing processing capacity approximately 10%-15% by investing $17.0 - $20.0 million during 2013. This expansion is expected to have a less than two-year payback and increase the mine's annual production to over 6.0 million ounces of silver for the next several years at reduced cash operating costs per ounce1. This expansion project remains on-schedule to be completed late this year.

• In celebration of the city ofPotosi'sbicentennial, San Bartolomé donated silver bars which were made into commemorative medallions for the government.
• Sales and operating cash flow1totaled $33.1 million and $11.9 million, respectively, in the first quarter 2013.
• Capital expenditures were $0.5 million during this quarter.

Rochester,Nevada- Slow First Quarter; Accelerated Production Expected during Remainder of 2013

• Rochesterproduced 648,000 ounces of silver and 8,742 ounces of gold, up 47% and 65% respectively, over the first quarter 2012. Cash operating costs per silver ounce1were $13.54, which were materially lower than first quarter 2012, but higher than fourth quarter 2012.
• In the fourth quarter 2012,Rochesterproduced 828,000 ounces of silver and 12,054 ounces of gold at cash operating costs of $2.17 per silver ounce1. First quarter production was lower due to poor weather and lower than planned crushing rates.
• The Company is investing approximately $4.0 million during 2013 to expand the capacity of the primary crusher from 9.0 million tons to 14.0 million tons. Crusher throughput is expected to ramp up to achieve 1.2-1.4 million tons crushed monthly in the second half of 2013, leading to higher second half silver and gold production.
• In addition, the Company is expanding the mine's heap leach capacity to approximately 67.0 million tons at an estimated capital cost of approximately $15.0 million. This planned expansion will accommodate sustained higher production rates driven by the processing of ore contained in historic stockpiles. These stockpiles were created during the mine's 26-year operating history when gold and silver prices were significantly lower than current market prices.
• On May 1, 2013,RochesterpresentedNevadaGovernorBrian Sandovalwith a 1,000-ounce silver bar to be made into 1,000 commemorative coins to mark the state's sesquicentennial.
• Sales and operating cash flow1totaled $39.5 million and $17.4 million, respectively, in the first quarter 2013.
• Capital expenditures were $3.3 million during this quarter.

Kensington,Alaska- Improving Gold Grade Expected in Second Half of 2013

• Kensingtonproduced 25,206 ounces of gold at cash operating costs of $1,055 per ounce1, significantly improved over the first quarter 2012, which was affected by the temporary scale back in production from November 2011 until April 2012 to allow for the completion of several critical underground and surface infrastructure projects.
• Production during the fourth quarter 2012 totaled 28,717 gold ounces at cash operating costs of $1,065 per ounce.1
• Kensington'smill throughput at 129,057 tons was consistent with the fourth quarter 2012. Average mill head grade of 0.20 oz/t was 13% lower than the fourth quarter 2012, but 11% higher than first quarter 2012.
• The gold grade is expected to gradually improve during the remaining quarters of 2013 as higher-grade stopes are mined and processed.
• Rebuilds of generators during the first quarter limited backfilling rates, which negatively impacted overall efficiency and costs.
• Sales and operating cash flow1totaled $39.3 million and $15.2 million, respectively, for the first quarter 2013.
• Capital expenditures were $3.3 million during this quarter.

La Preciosa,Mexico- Project Update

• The acquisition of Orko Silver closed on April 16 for total consideration of the approximately $280 million ($99.1 million in cash, 11.6 million Coeur shares and 1.6 million Coeur warrants.)

Exploration Update

During the first quarter, the Company invested $6.8 million in expensed exploration for discovery of new mineralization and $1.7 million in capitalized exploration for definition of new mineralization to at least an indicated resource category, completing nearly 138,000 feet (42,000 meters) of drilling and trenching.

Coeur's exploration program utilized up to 10 drill rigs and a trenching crew: four drills at Palmarejo, three atKensington(including one drill devoted to definition drilling), two inArgentina(Joaquin and Lejano projects), one atRochesterand the trenching crew at San Bartolomé.

Palmarejo,Mexico

• Drilling for discoveries of new mineralization was conducted around the Palmarejo surface and underground mines to test new targets generated in 2012.
• Drilling was performed underground on the 108 zone at Palmarejo and on the surface at theLas Animaszone at the southeastern part of the Guadalupe deposit to upgrade the confidence of and extend the known mineralized zones. Results received from both areas have been largely favorable and are expected to extend and upgrade the current mineralization at the 108 zone and atLas Animas.
  • At the 108 zone, hole DC3-108C-0091 intercepted 19.12 meters (62.7 feet) true width grading 124.7 grams/tonne silver (3.64 ounces/ton) and 3.62 grams/tonne gold (0.11 ounce/ton), and hole DC3-108C-0094 with 3.64 meters (11.9 feet) true width grading 1,561.3 grams/tonne silver (45.63 ounces/ton) and 33.13 grams/tonne gold (0.97 ounce/ton).
  • AtLas Animas, hole TDGH-509 intercepted 5.9 meters (19.4 feet) true width grading 108.3 grams/tonne silver (3.16 ounces/ton) and 0.82 grams/tonne gold (0.024 ounce/ton), and hole TDGH-519 with 4.7 meters (15.4 feet) true width grading 697.7 grams/tonne silver (20.35 ounces/ton) and 6.94 grams/tonne gold (0.20 ounce/ton). Both intercepts were within 100 meters (328 feet) of surface.
• The third phase of metallurgical sampling atLa Patria, a silver-gold near surface deposit located approximately 9 kilometers from the main Palmarejo mine, continued to test the amenability of the current mineralized zones to cyanidation recovery methods.

Kensington,Alaska

• Drilling during the first quarter was mostly devoted to production definition drilling in order to develop stoping (mining) blocks from year-end reserves.
• Exploration drilling focused on upgrading and expanding existing mineralized zones to be used in subsequent reserve estimation, mostly at zones 10 and 50 of the mainKensingtondeposit.
• In addition, drilling was performed at the Comet target, which is situated about 5,000 feet (1,500 meters) southeast of the high-grade, narrow vein Raven deposit. Assays are pending.
• New assay results from the Kensington South zone drilled in the fourth quarter 2012 showed potential for Kensington-style mineralization from this large, relatively untested area. Kensington South is situated south of the mainKensingtondeposit. To facilitate future drilling, construction of a new cross-cut drift began in the first quarter with completion of 430 feet (131 meters) of the planned 750 feet (229 meters).

Rochester,Nevada

• Continuing the exploration focus of 2012, drilling was performed to define grades and tons of existing stockpiles. In the first quarter, over 27,600 feet (8,400 meters) of reverse circulation rotary drilling was completed on two of the stockpiles called South and Limerick with favorable results reported.

  • At Limerick, hole LMD12-131 intercepted 20 feet true width grading 0.9 ounce/ton silver and 0.003 ounce/ton gold and hole LMD12-145 with 180 feet true width grading 0.67 ounce/ton silver and 0.002 ounce/ton gold.

• Drilling is also planned for the West and Charlie stockpiles during 2013. This work, along with metallurgical sampling, will continue throughout most of this year.

San Bartolomé,Bolivia

• All of the work in the first quarter was devoted to upgrading the confidence and extending known mineralization of the Pucka Loma zone in the northwest sector of the San Bartolomé mine area.
• The next stage of work will be to prepare a new model of the mineralization to be used in reserve estimation. To date, two-thirds of the completed trenches encountered bedrock at the base of the gravel (pallaco) mineralized layers. The remainder represents an opportunity to extend the thickness of the mineralized gravels.
• Exploration trenching will now shift to new targets around the mine.

2013 Outlook

Coeur's estimated 2013 silver and gold production guidance is unchanged and the mine-by-mine 2013 production outlook is provided in Table 4 below.

Coeur has adjusted its full-year 2013 projected cash operating costs1to $9.50 - $10.50 per silver ounce, assuming a gold by-product price of $1,500 per ounce for the last nine months of 2013.

Kensington'sestimated cash operating costs1are unchanged at $900 - $950 per gold ounce for 2013.
