MONTREAL (Scrap Monster): Capstone Copper has agreed to sell its Cozamin copper-silver-zinc-lead mine in Mexico to Luca Mining for total consideration of up to $385 million, as the company shifts capital toward larger copper development opportunities in Chile and the United States.

Roughly 84% of the maximum deal value is fixed or scheduled. Capstone is set to receive $290 million at closing and another $35 million one year later, while the remaining $60 million depends on future LME copper prices between 2027 and 2029.
Deal Includes Cash, Shares and Copper-Linked Payments
Under the terms of the transaction, Capstone will receive $275 million in cash and $15 million in Luca Mining shares upon closing.
An additional $35 million will be payable one year after completion.
Capstone could also receive up to $60 million in contingent payments linked to average annual London Metal Exchange copper prices between 2027 and 2029. The amount will be calculated at the end of each year based on the average annual LME copper price.
Capstone Redirects Capital Toward Larger Copper Projects
Capstone said the proceeds will strengthen its balance sheet and provide additional flexibility to advance its growth pipeline.
The company's priorities include the Santo Domingo copper-iron-gold project in Chile and the Mantoverde Optimized expansion.
The sale reflects Capstone's broader strategy of reallocating capital toward larger copper development opportunities.
Cozamin Mine Life Extends to 2030
Located in Zacatecas, Mexico, the Cozamin operation currently has a mine life extending to 2030.
Additional exploration work is planned following completion of the transaction, with the aim of extending the mine life and supporting longer-term cash flow.
Luca Mining Expands Mexican Portfolio
The acquisition will expand Luca Mining's production base in Mexico to three mines.
For Capstone, the divestment will reduce exposure to a smaller operating asset while freeing capital for larger-scale copper projects elsewhere in its portfolio.
