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. Cabin Radio
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. ExxonMobil
Rio Tinto’s latest push comes as copper stays front and center in the story major miners are selling to investors. On Tuesday, Rio Tinto Chief Executive Simon Trott took the stage at Bank of America’s Global Metals, Mining & Steel Conference in Miami. The company’s results in February described its growth pipeline as “anchored in copper.” Investegate
The application lays out low-impact exploration methods—think aerial and ground surveys, collecting samples, marking out claims, group prospecting, geological mapping. Staking here refers specifically to establishing and recording mineral claims, not constructing a mine. According to Rio Tinto, the team plans to use helicopters, with field crews working from June 15 through Aug. 31. The temporary camp won’t exceed 14 people.
Sam Russell, principal geoscientist at Rio Tinto Exploration Canada, said in a cover letter to the Sahtu Land and Water Board that the company’s target for kicking off the project is July 24, 2026. Alongside the letter, the filing package features an engagement plan, waste management plan, spill contingency plan, plus a wildlife management and monitoring plan.
Rio Tinto wants a Type A land-use permit—basically, the green light for work on land, though it’s not the same as a mining licence. According to Cabin Radio, the company’s application covers four years, but there’s no drilling, permanent camp, or road building in the current plans.
Rio Tinto’s exploration team is negotiating a land-access deal with the Tulita District Land Corporation, which acts for the Tulita Land Corporation, the Tłegǫ́hłı̨ Got’įnę Government, and the Fort Norman Métis Community, according to Cabin Radio. The proposed exploration zone brushes up against outfitting camps, Ten Stone Mountain Lodge, and a stretch of the old World War Two-era Canol Trail. Cabin Radio
Sahtu MLA Danny McNeely threw his support behind the project in a May 6 letter to regulators, saying, “The Sahtu can be a major destination for responsible resource development.” He’s pitching the plan as a potential draw for investment, jobs, and infrastructure—so long as it’s managed responsibly.

The competition was on display. BHP—Rio Tinto’s heavyweight rival in diversified mining—had President Americas and CEO-elect Brandon Craig lined up to speak at the Bank of America conference just half an hour after Rio Tinto’s spot on Tuesday. TipRanks flagged BHP’s session as focused on the leadership shuffle and its latest investor deck. Investegate
BHP’s March succession update highlighted that Craig oversees growth strategy in Canada, the US, and South America, pointing out that under his watch, BHP claimed the top spot as the world’s biggest copper producer in the Americas role. For the majors, convincing investors they can deliver credible copper growth while keeping an eye on costs is the key angle here. BHP
The real possibility: CopperCap remains just a dot on a map, an early-stage idea that never advances. Rio Tinto’s current application skips drilling entirely. Moving from surface samples to an actual mine? That would mean new permits, financial justification, deals with local communities, and a slog that could stretch for years. Cabin Radio points out, a copper mine here could be decades away—if it happens at all. Cabin Radio
