About Coeur Mining

Coeur Mining, Inc. (Coeur) is a precious metals producer with assets located in the United States, Canada, and Mexico. Strategy Coeur’s strategy is to be a well-diversified, growing precious metals producer with a focus on generating sustainable. The company’s strategy is guided by its purpose statement. Operating Segments The company produces and sells precious metals from the following operating segments: The Palmarejo gold-silver complex, located in the state of Chihuahua in Northern Mexico. The processing facility at the Palmarejo complex is fed by the Guadalupe, Independencia and La Nación underground mines. The company also carries out exploration activities across the Palmarejo property package. The Rochester open pit heap leach silver-gold mine located in northwestern Nevada. Coeur Rochester commenced a significant expansion project in 2020 (Plan of Operations Amendment No. 11, or POA 11) consisting of construction of a new leach pad, crushing facility, process plant and related infrastructure, which is expected to support an extended mine life. The construction of POA11 was completed in the fourth quarter of 2023. Coeur Rochester also acquired the Lincoln Hill, Gold Ridge, and related exploration assets adjacent to its Rochester mine in 2018. The Kensington underground gold mine located north of Juneau, Alaska. Coeur Alaska received a favorable final Record of Decision from the Forest Service for its Plan of Operations Amendment 1 (POA 1) on February 24, 2022. POA 1 gives Coeur Alaska the ability to increase tailings and waste rock storage capacity to support an expected longer mine life, reflecting positive exploration results, current metal prices, and ongoing operational efficiencies. Coeur Alaska is working on a multi-year exploration and underground development plan including obtaining supplemental permit requirements following this significant milestone. The Wharf open pit heap leach gold mine located near Lead, South Dakota, which was acquired by Coeur in 2015. In addition, the company operates the Silvertip underground silver-zinc-lead exploration project located in northern British Columbia, Canada, which was acquired by Coeur in 2017. Silvertip commenced commercial production ramp up in 2018. In February 2020, the company announced a suspension of mining and processing activities at Silvertip. While mining activities are suspended, the company is investing in exploration to potentially further expand the resource and extend the mine life. Metal Processing, Marketing and Sales The company produces gold and silver dore, as well as gold concentrate. The dore produced at the Palmarejo complex and Rochester mine, as well as the electrolytic cathodic sludge produced by the Wharf mine, is refined by a geographically diverse group of third-party refiners into gold and silver bullion according to benchmark standards set by the London Bullion Market Association, which regulates the acceptable requirements for bullion traded in the London precious metals markets. The company then sells gold and silver bullion to multi-national banks, bullion trading houses, and refiners across the globe. The company’s gold concentrate product from the Kensington mine is sold under a long term offtake agreement and is shipped to geographically diverse third-party smelters.
