Company Overview

Marimaca Copper Corp. is a Canadian-based mineral exploration and development company focused on the discovery and advancement of copper resources in Chile, one of the world’s largest copper-producing jurisdictions. The company operates in the base metals mining and exploration industry, with a primary emphasis on copper oxide and sulphide deposits. Its core value proposition is the advancement of high-quality copper assets with potential for low capital intensity and scalable development.

The company’s principal asset and primary revenue driver prospect is the Marimaca Oxide Deposit, which has positioned Marimaca Copper as a notable emerging copper developer rather than a diversified producer. The company targets global copper markets that are supported by long-term demand drivers such as electrification, renewable energy, and electric vehicles. Marimaca Copper was originally incorporated as a junior exploration company and has evolved through systematic exploration success, resource delineation, and preliminary economic studies that elevated it toward the development stage.

Business Operations

Marimaca Copper’s business operations are centered on mineral exploration, resource definition, and project advancement, with all material assets located in Chile. The company operates through its wholly owned Chilean subsidiaries that control mineral concessions and surface rights associated with the Marimaca Project, located in the Antofagasta Region. Revenue generation has not yet commenced, as the company remains in the pre-production phase and is focused on technical studies, permitting, and exploration expansion.

The company’s operations emphasize geological modeling, drilling programs, metallurgical testing, and engineering studies to support future development decisions. Marimaca Copper controls exploration technologies and geological data specific to its land package and maintains relationships with local contractors and technical consultants. There are no disclosed producing joint ventures; however, the company maintains strategic relationships with engineering firms and service providers supporting feasibility and development planning.

Strategic Position & Investments

Strategically, Marimaca Copper is focused on advancing the Marimaca Oxide Deposit toward a potential development decision while continuing to expand the resource base through exploration of adjacent targets and deeper sulphide mineralization. Growth initiatives include step-out drilling, metallurgical optimization, and the evaluation of processing routes that could enhance project economics. The company’s strategy emphasizes disciplined capital allocation and incremental derisking through technical milestones.

The company has made targeted investments in land consolidation and exploration across its broader Marimaca land package, which includes multiple satellite prospects surrounding the core deposit. Marimaca Copper is also evaluating the long-term potential of underlying sulphide resources beneath the oxide mineralization, positioning the project for possible staged development. Data on additional acquisitions or downstream investments is limited, and no diversified portfolio companies beyond the core project have been conclusively verified from public disclosures.

Geographic Footprint

Marimaca Copper’s operational footprint is concentrated entirely in Chile, with its flagship asset located in the Antofagasta Region, a globally significant copper mining district. This region hosts extensive mining infrastructure, skilled labor availability, and established regulatory frameworks that support large-scale mining operations. The company benefits from proximity to existing roads, ports, and power infrastructure serving the northern Chilean mining corridor.

The company is headquartered in Canada, reflecting its status as a publicly listed issuer on the Toronto Stock Exchange. While it does not maintain operating assets outside Chile, Marimaca Copper has an international investor base and engages with global capital markets. Its influence and strategic relevance are tied to Chile’s role in global copper supply rather than a diversified multinational operating presence.

Leadership & Governance

Marimaca Copper was founded by a group of mining professionals with extensive experience in Latin American exploration and development. The leadership team emphasizes technical rigor, capital discipline, and long-term value creation through responsible resource development. Governance practices align with Canadian public company standards, with oversight provided by an independent board of directors.

Key executives and leadership include:

• Hayden Locke – President and Chief Executive Officer
• Gavin Waddington – Chief Financial Officer
• Sergio Rivera – Vice President, Exploration
• Nick DeMare – Vice President, Corporate Development
• Derek Byles – Chairman of the Board

The leadership team’s strategic vision centers on advancing Marimaca Copper into a development-stage company while maintaining flexibility to respond to market conditions and potential strategic opportunities.
