Adjusted All-in Sustaining Costs Declined 8% to $17.66 per Silver Equivalent Ounce

Adjusted Costs Applicable to Sales of $13.71 per Silver Equivalent Ounce and $797 per Gold Ounce

Chicago, Illinois – May 4, 2015 – Coeur Mining, Inc. (the "Company" or "Coeur") (NYSE: CDE) reported first quarter 2015 revenue of $153.0 million, adjusted EBITDA¹ of $21.7 million, and adjusted net loss¹ of $0.24 per share. Adjusted all-in sustaining costs declined 8% from the fourth quarter of 2014 to $17.66 per silver equivalent ounce¹, the lowest level in the two years of reporting this metric. Adjusted costs applicable to sales per silver equivalent ounce¹ of $13.71 declined 5% from the fourth quarter.

"We are off to a strong start in 2015, tracking at or below our annual cost guidance in the first quarter. Falling oil prices and a weakening Mexican peso bode well for further cost improvement, as fuel represents approximately 7% of our total operating costs and about 50% of Palmarejo's costs are denominated in pesos," said Mitchell J. Krebs, Coeur's President and Chief Executive Officer. "In the past three months we closed two acquisitions, released a high-grade, high-margin, re-scoped mine plan for Kensington reflecting a significant new discovery, and announced a near-doubling in silver equivalent reserves at Palmarejo, reflecting higher grades from our Paramount acquisition and last year's discovery at Independencia. These are all important steps in our strategy to reduce unit costs, produce higher-quality ounces, and generate free cash flow at current metal prices. With $180 million in cash and cash equivalents, maintaining sufficient liquidity and a flexible balance sheet remains a top priority."

Financial Highlights (Unaudited)

Financial Results

First quarter 2015 revenue increased $12.4 million, or 9%, compared with the fourth quarter of 2014 to $153.0 million due to a 4% increase in silver equivalent ounces sold and slightly higher metal prices. Average realized silver and gold prices each increased 2% compared to the fourth quarter, at $16.77 per ounce for silver and $1,204 per ounce for gold. Silver contributed 45% of metal sales and gold contributed 55% during the first quarter.

General and administrative expenses decreased 2% from the fourth quarter to $8.8 million in the first quarter, and were down 37% compared to the first quarter of 2014. Capital expenditures of $17.6 million in the first quarter declined 12% compared to the fourth quarter.

Adjusted net loss¹ was $24.4 million or $0.24 per share in the first quarter, improved from a loss of $37.5 million, or $0.37 per share, in the fourth quarter mainly due to lower unit operating costs. The first quarter adjusted net loss¹ mainly excludes inventory adjustments to net realizable value, foreign exchange losses on deferred taxes, and fair value adjustments to royalty obligations and metal hedging contracts.

Cash flow used in operating activities was $4.0 million in the first quarter, which included a $14.4 million increase in working capital, mainly due to accrued interest, payroll, and other benefits. Inventory was nearly unchanged during the quarter, with inventory reductions at Kensington and Rochester mostly offset by a $6.7 million increase at Wharf, as no sales were recorded in the first quarter due to the shipping schedule at the mine.

Coeur entered into a short-term credit facility with The Bank of Nova Scotia for $50.0 million, which raised the total debt balance to $513.5 million as of March 31, 2015, including $437.5 million in senior unsecured notes due in 2021. Cash, cash equivalents, and short-term investments totaled $179.6 million at the end of the first quarter, yielding a net debt balance of $333.9 million.

Operations

Highlights of first quarter 2015 results for each of the Company's operating segments are provided below.

Palmarejo, Mexico

• Adjusted costs applicable to sales per silver equivalent ounce¹ of $14.56 decreased 7% from the fourth quarter of 2014
• Recovery rates for silver and gold declined in the first quarter due to test work completed in the processing plant during the quarter
• Cash flow from operating activities of $(0.2) million included a $4.5 million increase in working capital
• Palmarejo continues to transition to underground mining at the Guadalupe mine and the Independencia mine (beginning early 2016) while mining activities in the historic zones gradually decline
• Open-pit operations are expected to end in the third quarter of 2015 and underground mining at the legacy zones is expected to end by January 2016
• The acquisition of Paramount closed April 17, 2015. On April 27, 2015, Coeur announced an 89% increase in silver reserves and 76% increase in gold reserves at Palmarejo, mainly from the addition of certain Paramount assets. The increase contains an average silver reserve grade 31% higher than Palmarejo's reserves as of December 31, 2014
• Palmarejo's reserves now total 54.0 million silver ounces and 876,000 gold ounces. Compared to just fifteen months ago, silver reserves have increased 30% and gold reserves have increased 54%. Most importantly, the average silver reserve grade has increased 32% and the average gold reserve grade has increased 55%
• In 2015, Palmarejo is expected to produce 3.9 – 4.3 million ounces of silver and 55,000 – 65,000 ounces of gold at costs applicable to sales per silver equivalent ounce¹ of $16.25 – $17.75

Rochester, Nevada

• First quarter adjusted costs applicable to sales per silver equivalent ounce¹ were $12.95, down 6% from the fourth quarter due to lower crushing and leaching costs
• The average silver grade increased 23% compared to the fourth quarter and silver equivalent ounces sold increased 21%
• Free cash flow³ of $13.1 million in the first quarter was the highest since the fourth quarter of 2012, when realized silver and gold prices averaged $32.52 per ounce and $1,709 per ounce, respectively
• Approval for POA 10 (expansion of Stage 4 leach pad and construction of new Stage 5 leach pad) is expected by early 2016
• In 2015, Rochester is expected to produce 4.7 – 5.0 million ounces of silver and 55,000 – 65,000 ounces of gold at costs applicable to sales per silver equivalent ounce¹ of $12.50 – $14.00

Kensington, Alaska

• Free cash flow³ at Kensington of $8.2 million increased from $(7.6) million in the fourth quarter of 2014 due to a 65% increase in gold ounces sold
• A 14% increase in average gold grade enabled lower throughput in the first quarter, with adjusted costs applicable to sales per gold ounce¹ below $800 for the second consecutive quarter
• Coeur released a re-scoped mine plan at Kensington on April 14, 2015, reflecting the impact of the recently discovered high-grade Jualin zone. Mining rates at Jualin are expected to peak in 2018-2019 when annual production at Kensington is expected to average approximately 143,000 ounces at costs applicable to sales per gold ounce of approximately $760. Recent drilling results suggest the potential to grow the resource at Jualin and extend the 2017 -2019 production profile
• In 2015, Kensington is expected to produce 110,000 – 115,000 ounces of gold at costs applicable to sales per gold ounce of $900 – $975

San Bartolomé, Bolivia

• Maintenance downtime and heavy rain resulted in processing a greater proportion of stockpiled ore in the first quarter, which negatively impacted the grade and recovery rates. Despite this, adjusted costs applicable to sales per silver equivalent ounce¹ remained stable with the fourth quarter of 2014 at San Bartolomé
• Free cash flow¹ of $4.1 million in the first quarter increased from $0.3 million in the fourth quarter of 2014 due to lower working capital
• In 2015, San Bartolomé is expected to produce 5.8 – 6.1 million ounces of silver at costs applicable to sales per silver equivalent ounce¹ of $13.50 – $15.00

Wharf, South Dakota

• There were no metal sales at Wharf from the February 20, 2015 transaction closing date through the end of the first quarter, as the mine has historically maintained a monthly shipping schedule. The first ore shipment after the transaction closed was in mid-March and the corresponding metal sale occurred in April. Going forward, Coeur expects to increase the frequency of ore shipments at Wharf to more closely align the timing of metal sales with production
• In 2015, Wharf is expected to produce 74,000 – 78,000 ounces of gold at costs applicable to sales per gold equivalent ounce¹ of $750 – $825

Coeur Capital

• There are five cash-flowing royalties and streams, four non-cash-flowing royalties, and ten investments in junior mining companies held in Coeur Capital or its affiliates
• Coeur Capital's largest source of cash flow is the silver stream on the Endeavor mine in New South Wales, Australia in which the Company owns 100% of the silver up to a total of 20.0 million payable ounces. At March 31, 2015, the Company has received 5.6 million ounces, or 28.0% of the total

Exploration

Costs associated with exploration activities for the first quarter of 2015 were $4.3 million (expensed) for discovery of new silver and gold mineralization and $4.0 million (capitalized) for definition and expansion of mineralized material. These amounts compare to exploration costs of $5.7 million expensed and $2.9 million capitalized in the fourth quarter of 2014. Coeur's exploration program used 10 drill rigs during the first quarter: 4 drills at Palmarejo, 4 at Kensington, and 2 at Rochester. This work resulted in completion of over 86,931 feet (26,496 meters) of combined core and reverse circulation drilling. Coeur announced high-grade drill results at Kensington on April 14, 2015 and at Palmarejo on April 28, 2015, demonstrating Coeur's continued success finding high-grade mineralization near existing infrastructure. 

Exploration expenses are expected to total $13 – $16 million in 2015, with additional capital allocated to resource conversion. Coeur will continue to use a success-based approach to evaluate exploration needs on an ongoing basis.

2015 Outlook

Coeur's 2015 total production and cost guidance is shown below. Coeur is raising its guidance for capital expenditures to $95 – $105 million compared to prior guidance of $85 – $95 million as well as its guidance for exploration expenses to $13 – $16 million from $10 – $12 million for 2015. Prior guidance did not include development capital and exploration expenses related to the acquisition of Paramount Gold and Silver Corp.

2015 Production Outlook

2015 Cost Outlook

Downside Price Protection

The Company's downside metal price protection program uses put spreads to protect a portion of expected future production against a sharp decrease in metal prices, while selling intra-quarter, out-of-the-money call options when appropriate to offset the net cost of the put spreads. Put spreads settled and calls sold during the first quarter of 2015 generated cash flow of $1.6 million. Put spreads for the second quarter of 2015 cover 900,000 ounces of expected silver production per month with strike prices of $17 per ounce on options purchased and $15.50 per ounce on options sold.

Non-U.S. GAAP Measures

We supplement the reporting of our financial information determined under United States generally accepted accounting principles (U.S. GAAP) with certain non-U.S. GAAP financial measures, including adjusted EBITDA, adjusted net income (loss), costs applicable to sales per silver equivalent ounce (or per gold equivalent ounce), adjusted costs applicable to sales per silver equivalent ounce, all-in sustaining costs, and adjusted all-in sustaining costs. We believe that these adjusted measures provide meaningful information to assist management, investors and analysts in understanding our financial results and assessing our prospects for future performance. We believe these adjusted financial measures are important indicators of our recurring operations because they exclude items that may not be indicative of, or are unrelated to our core operating results, and provide a better baseline for analyzing trends in our underlying businesses. We believe adjusted EBITDA, adjusted net income (loss), costs applicable to sales per silver equivalent ounce (or per gold equivalent ounce), adjusted costs applicable to sales per silver equivalent ounce, all-in sustaining costs, and adjusted all-in sustaining costs are important measures in assessing the Company's overall financial performance.

Notes

1. Adjusted EBITDA, adjusted net income (loss), all-in sustaining costs, adjusted all-in sustaining costs, costs applicable to sales per silver equivalent ounce (or per gold equivalent ounce), and adjusted costs applicable to sales per silver equivalent ounce are non-GAAP measures. Please see tables in the Appendix for the reconciliation to U.S. GAAP. For purposes of silver and gold equivalence, 60:1 silver to gold ratio.
2. Includes capital leases. Net of debt discount.
3. Free cash flow is defined as cash flow from operating activities less capital expenditures and royalty payments.
