Red Chris mine expansion

The expansion of the Red Chris copper-gold mine in northwest British Columbia to an underground block cave, owned 70% by Newmont and 30% by Imperial Metals. It was among the first five projects referred to the Major Projects Office (11 September 2025). British Columbia granted an amended environmental assessment certificate, reached through a consent-based process with the Tahltan Nation, and an amended Mines Act permit; Ottawa committed C$500 million under the Canada–BC agreement of 2 July 2026. Newmont had not taken a final investment decision (Newmont).
