Try Dealroom →, a Canadian developer listed on the Toronto Venture Exchange, through a private placement. The deal, structured with Canada's G Mining GroupDealroom has a profile for this one. Try Dealroom → via a jointly owned special purpose company, gives Sumitomo an economic stake of roughly 25% in Tintina and its Dos Amigos copper and gold project in Atacama, Chile.
What's the endgame? The proceeds will fund Tintina's acquisition of 100% of the project's interests and push it toward a final investment decision. A 2026 preliminary economic assessment estimated about 1.01 billion tonnes of measured and indicated mineral resources, plus 2.56 billion tonnes of inferred resources.
Why here? Nearby mines let the project tap existing transport and power infrastructure, and its relatively low altitude eases development. Sumitomo also cites potential for additional deposit discoveries in the surrounding area.
Why now? Sumitomo has named copper a key strategic area, betting on rising demand. Beyond large-scale projects, it is targeting early-stage developments to build its resource base.
The G Mining Group, founded in Canada in 2006, provides engineering and construction services for mine development and has delivered projects on schedule and on budget for major miners. The two partners run a joint business development vehicle, G Mining Capital Inc.Dealroom has a profile for this one. Try Dealroom →, which sourced and structured the Dos Amigos deal.
The signal: At roughly C$48 million, the round sits in the 96th percentile of non-VC private placements in Canadian energy over the past 48 months, across 2,276 comparable deals. It marks a bet that pairing a trading house's capital and networks with a specialist builder can de-risk copper supply as demand climbs and easy deposits grow scarce.
