Capstone Copper Corp. has announced its 2026 annual production, cost, and capital expenditure guidance. The company expects consolidated copper production to be between 200,000 and 230,000 tonnes in 2026, largely stable compared to 2025. Consolidated C1 cash cost guidance is expected to be within $2.45 to $2.75 per payable pound of copper, an increase from 2025 primarily due to modest inflation and the impact of lower-grade zones at Mantos Blancos and Pinto Valley. Total sustaining capital expenditures are forecast to be $270 million in 2026, including $90 million for tailings and ESG initiatives. Expansionary capital expenditures are expected to be $225 million, primarily related to the Mantoverde Optimized Project and the Santo Domingo Project. The company also plans to spend $225 million on capitalized stripping at its three open-pit mines. Exploration expenditures are expected to be $70 million as the company advances its district exploration strategy across the portfolio.
