Cozamin is a 100%-owned underground copper-silver-zinc-lead mine and flotation operation near Zacatecas City. Capstone mines the Mala Noche Vein and Mala Noche Footwall Zone using long-hole stoping and cut-and-fill methods, supported by paste backfill and filtered-tailings infrastructure. Wheaton's silver stream covers 50% of silver production until 10 million ounces have been delivered and 33% thereafter; Capstone reported 3.3 million ounces delivered through March 31, 2026. The December 31, 2025 reserve contains 6.657 Mt and supports the operating plan toward 2030, while ongoing drilling targets reserve conversion and extensions of the principal vein systems.
