Wharf is an open-pit, heap-leach gold operation located in the Northern Black Hills of South Dakota, wholly owned and operated by Coeur Mining. Since acquiring the mine from Goldcorp Inc. in 2015, Coeur has improved plant efficiency and continued to replace and expand Mineral Reserves and Resources through ongoing exploration. In February 2026, Coeur released an updated technical report for Wharf that extended the mine life to approximately 12 years. Proven and Probable Mineral Reserves increased 65% to 1.25 Moz of gold at 0.71 g/t, while Measured and Indicated Mineral Resources totaled 1.19 Moz of gold and Inferred Mineral Resources totaled 1.49 Moz of gold. The updated mine plan was supported by drilling at the Juno and North Foley deposits.
In 2025, Wharf produced 97,327 ounces of gold. Coeur has provided 2026 production guidance of 72 to 90 koz of gold. Production is expected to increase through the year following installation of a new tertiary crushing system in the second quarter of 2026 after a fire damaged the existing crusher in the fourth quarter of 2025.
Recent exploration at Wharf has focused on expansion and infill drilling at Juno and North Foley with the objective of extending mine life. In 2026, exploration is expected to remain focused on further reserve conversion at Juno and North Foley and on continuing to build the broader prospect pipeline.
Metalla holds a 1.0% royalty on gold produced from ores mined and stacked on Wharf’s heap-leach pad or recovered from tailings. Metalla accrued 825 GEOs from Wharf in 2025.
