Marimaca Copper Limited (OTCMKTS:MARIF) is a copper exploration and development company focused on advancing its flagship Marimaca oxide copper project in the Antofagasta region of northern Chile. The company’s principal business activities include exploration, resource definition, and feasibility studies aimed at delineating and de-risking a near-surface oxide copper deposit with the potential for low-cost, sustainable copper production.
The Marimaca project sits approximately 75 kilometers northeast of the port city of Antofagasta and benefits from established regional infrastructure, including paved highways, power lines, water supply and port access. Since acquiring the project, Marimaca Copper has completed extensive drilling programs that have defined a significant oxide copper resource and supported a series of technical studies, including scoping and pre-feasibility assessments.
Marimaca Copper’s development strategy centers on a modular heap-leach operation designed to produce copper cathode using proven solvent extraction and electrowinning (SX–EW) technology. The company continues to advance permitting processes and engage with local stakeholders to secure environmental approvals and community support. Subsequent studies have focused on optimizing recovery rates, minimizing environmental footprint and evaluating expansion potential.
Led by an experienced management team with backgrounds in exploration, metallurgical engineering and project financing, Marimaca Copper maintains corporate offices in Santiago, Chile, and Perth, Australia. The leadership group has a track record of bringing greenfield copper projects into production and is committed to responsible resource development in one of the world’s premier copper-producing regions.
