Marimaca Copper Limited is a mineral exploration and development company focused on the advancement of the Marimaca oxide copper project in northern Chile. The company holds a 100% interest in a high‐grade copper oxide deposit located in the Antofagasta Region, where it is progressing through feasibility and permitting stages toward potential commercial production. Marimaca Copper’s flagship project leverages heap leach extraction and solvent‐extraction electrowinning (SX‐EW) methods to produce copper cathode for industrial and electrical markets.
Originally incorporated as Coro Mining Corp, the company rebranded to Marimaca Copper in 2021 to reflect its strategic focus on the Marimaca deposit. Since then, it has completed a preliminary feasibility study that outlines a multi‐year production profile and development timetable. The project benefits from established infrastructure in northern Chile, including access to roads, power and water, and proximity to port facilities for concentrate export.
Marimaca Copper maintains a Vancouver office for corporate and investor relations, while its technical and operational teams are based in Chile to oversee on‐site exploration, metallurgical testing and environmental planning. Under the leadership of Chief Executive Officer Scott Prosser, the company has also advanced satellite targets within its regional land package, aiming to expand the resource base and establish a pipeline of development opportunities.
With copper viewed as a critical metal for electrification and renewable energy technologies, Marimaca Copper positions itself to supply high‐purity cathode to global markets. The company’s near‐term objectives include securing final environmental approvals, completing detailed engineering studies and mobilizing construction activities to deliver its first copper production in the coming years.
