Marimaca Copper Corp. Advances MOD Toward Development with C$409 Million Equity Offering

Marimaca Copper Corp., a Chile-focused copper developer listed on the Toronto Stock Exchange (TSX) and Australian Securities Exchange (ASX), has made significant progress in advancing its flagship Marimaca Oxide Deposit (MOD) toward development. In February 2026, the company completed a global equity offering of approximately C$409 million, including an Australian tranche, which strengthened its balance sheet as it advances the MOD toward a final investment decision.

The project has continued to progress on permitting and engineering following its definitive feasibility study. Exploration at the Pampa Medina target, roughly 28 kilometers from the main deposit, has provided encouraging results, including high-grade sulphide intercepts through 2026. On July 7, 2026, an extension of the high-grade bornite zone was announced with results such as 6 meters at 6.11% copper and 24.0 g/t silver.

The company's Chilean coastal location near existing infrastructure and power is a significant cost advantage. Copper's investment case rests on a structural supply-demand gap, driven by electrification and renewable infrastructure requiring copper-intensive materials while new mines are scarce, capital-intensive, and slow to permit.

Key catalysts for Marimaca Copper Corp. include a formal construction or final investment decision, further permitting milestones, project financing arrangements, continued drilling at Pampa Medina and other targets, and updated technical studies. Copper-price movements will strongly influence sentiment and project economics.
