End year
2028
Mine life
25 years
Workforce
The mine employs approximately 220 Tahltans. An older source stated nearly 500 people are employed in total.
Production
For the 2024 calendar year, total production was 85,320,618 pounds of copper and 59,811 ounces of gold. Production for the 2023 calendar year was 57,051,467 pounds of copper and 46,046 ounces of gold. Newmont's guidance for 2025 is 88 million pounds of copper and 86,000 ounces of gold.
Processing
The processing plant uses a primary gyratory crusher, a semi-autogenous (SAG) mill, ball mill, and pebble crushing (SABC) comminution circuit. This is followed by a sequential flotation recovery circuit to produce a saleable gold-copper concentrate. The plant will be upgraded to support the underground operation, including a parallel single-stage SAG grinding circuit and additional flotation capacity.
Equipment
The mining fleet includes conventional truck and shovel methods. Specific equipment includes Sandvik Leopard™ DI650i and Sandvik DR412i blasthole drills, P&H 2800 electric cable shovels, and Caterpillar 793 and 785D haul trucks. The future underground block cave operation will require a new fleet of equipment, including jumbos, cablebolters, shotcrete machines, and agitator trucks.
Expansion
A major expansion to an underground block cave operation is being studied and is anticipated to extend the mine's life by more than a decade. A feasibility study for the block cave expansion is expected to be completed in the second half of 2026.

Overview
A past-producing mine being redeveloped as a conventional truck and shovel open-pit operation. The project is fully permitted and under construction. Skeena Resources acquired 100% ownership of the project from Barrick Gold in 2020. A Definitive Feasibility Study was completed in November 2023. The project is located in the Golden Triangle region of northwestern British Columbia, within the territory of the Tahltan Nation.
Production
Initial production and cash flow are anticipated in the second quarter of 2027. The mine is projected to produce an average of 260,000 ounces of gold and 7.65 million ounces of silver annually. Other estimates project between 0.20 and 0.25 million ounces of gold and between 5.5 and 7.0 million ounces of silver annually. The processing plant will have the capacity for up to 3.6 million tonnes of ore per year.
Processing
The project will utilise a simplified flowsheet with metallurgical optimisation to produce a gold-silver concentrate on-site. This concentrate will be transported to third-party smelters.
