Rio Tinto’s Copper Hunt In Canada’s North Comes Right As An Oil Town Faces Its Next Act
Rio Tinto is looking to start copper exploration in the Sahtu region of Canada’s Northwest Territories this summer, filing an application as regulators weigh the area’s future with its main oil site nearing shutdown. The miner wants the green light for its CopperCap project, set in the Mackenzie Mountains roughly 160 km from both Tulita and Norman Wells. That timing puts extra emphasis on the application—this isn’t just another field program. Imperial Oil is planning to wind down its Norman Wells oil and gas site, its oldest Canadian operation, with production ending in the third quarter of 2026 as the reservoir runs dry. The company expects closure, remediation, and reclamation will stretch across roughly 20 years.
