Coeur Mining Reports Substantial Expansion in Mineral Reserves

Coeur Mining US1921085049

Coeur Mining has released its updated reserve estimates for the end of 2025, revealing significant year-over-year improvements. The precious metals miner posted solid gains in both its gold and silver holdings, with two operations?Wharf in South Dakota and Palmarejo in Mexico?delivering particularly strong results. These updated figures provide a clearer picture of the company's future production potential.

A key factor in the revised calculations is Coeur's use of updated long-term commodity price assumptions. The company now models reserves using $2,200 per ounce for gold and $26 per ounce for silver. This marks an increase from the prior year's assumptions of $1,800 for gold and $23.50 for silver. Management notes these new benchmarks are closer to current market prices while remaining conservative to maintain a safety buffer.

The net result is a consolidated reserve base of 4.4 million ounces of gold and 274.4 million ounces of silver.

Wharf Mine Life Doubles on Reserve Growth

The most compelling development comes from the Wharf mine, where proven and probable gold reserves surged 65% to reach 1.25 million ounces. This substantial increase effectively doubles the estimated mine life to twelve years. For an asset that has already generated free cash flow well in excess of its original capital investment, this represents a remarkable extension of its value-generating timeline.

Palmarejo Shows Significant Upside, Especially in Eastern Zone

Coeur's Palmarejo complex in Mexico also demonstrated positive momentum. Gold reserves there increased by 36%, while silver reserves grew by 40%. Exploration efforts in the East Palmarejo area proved especially fruitful, with indicated resources jumping 86% higher. This suggests the region possesses considerably more mineralization than has been accounted for in current production plans.

Strategic Moves and Forthcoming Financials

These geological updates arrive alongside a busy period for the company. Coeur is currently integrating the strategic acquisition of New Gold Inc., which received shareholder approval in late January. Furthermore, the market awaits the company's fourth-quarter and full-year 2025 financial results, scheduled for release after today's market close. Investors will be watching to see if the operational and financial performance aligns with the strengthened resource base.

Additional strategic details are expected on February 24th, when CEO Mitchell J. Krebs presents at the BMO Global Metals, Mining & Critical Minerals Conference.
