Copper Mountain

Overview

The Copper Mountain Mine, located south of Princeton, British Columbia, is a conventional open pit, truck and shovel operation, and is wholly-owned by Hudbay. The mine has a 45,000 tonnes per day plant that utilizes a conventional crushing, grinding and flotation circuit to produce copper concentrates with gold and silver credits.

Copper, gold and silver production in Q1 2025 at Copper Mountain in British Columbia, was 7,196 tonnes of copper, 5,561 ounces of gold and 79,480 ounces of silver. Production of copper, gold and silver increased by 21%, 20% and 35%, respectively, compared to the fourth quarter of 2024, largely due to higher grades.

Hudbay is implementing plans to stabilize the operation by leveraging its efficient operating practices at Constancia. Optimization efforts at Copper Mountain are focused on executing the planned accelerated stripping program and mill throughput improvement projects, including the planned conversion of the third ball mill to a second SAG mill in the second half of 2025.

The current mineral reserve estimates at Copper Mountain total 346 million tonnes at 0.25% copper and 0.12 grams per tonne gold with approximately 850 thousand tonnes of contained copper and 1.3 million ounces of contained gold. The current mineral reserve estimates continue to support the mine life until 2043, with significant upside potential for future resource conversion and mine life extension beyond 19 years through an additional 125 million tonnes of measured and indicated resources at 0.21% copper and 0.10 grams per tonne gold and 372 million tonnes of inferred resources at 0.25% copper and 0.13 grams per tonne gold, in each case, exclusive of mineral reserves.

Evolve’s royalty covers a portion of the Copper Mountain claims, including the Alabama and Virginia deposits.
