Capstone Copper Sells Cozamin Mine to Luca for Up to $385 Million…

Event summary

Capstone Copper has agreed to sell its Cozamin copper-silver-zinc-lead mine in Mexico to Luca Mining Corp. for up to $385 million.
The deal includes $275 million in upfront cash, $15 million in Luca shares, $35 million in deferred consideration, and up to $60 million in contingent payments tied to copper prices.
The transaction is expected to close in Q4 2026, subject to regulatory approvals.
Capstone will retain exposure to Cozamin's exploration upside through its shareholding in Luca.

The big picture

Capstone's sale of Cozamin reflects a strategic shift to streamline its portfolio and focus on larger growth projects. The deal underscores the trend of mining companies divesting non-core assets to strengthen balance sheets and pursue higher-margin opportunities. Luca's acquisition aligns with its strategy of expanding its footprint in Mexico's prolific Sierra Madre mineralized belt.
