Company Overview

Marimaca Copper Corp. is a Canadian-based mineral exploration and development company focused on the acquisition, exploration, and development of copper projects in Chile, one of the world’s leading copper-producing jurisdictions. The company operates within the base metals mining industry, with a strategic emphasis on copper resources that are amenable to low-cost extraction methods. Marimaca Copper’s primary value driver is the advancement of its flagship copper oxide project, which is intended to support potential future development decisions rather than current production revenues.

The company’s core asset is the Marimaca Oxide Deposit, which is positioned as a near-surface, large-scale copper oxide system with potential for heap leach processing. Marimaca Copper differentiates itself through its focus on oxide copper mineralization in a mature mining district, leveraging existing infrastructure and proximity to major copper operations. The company was incorporated in 2016 and evolved from an early-stage explorer into a development-focused company following a series of successful exploration programs that confirmed the scale and continuity of its principal deposit.

Business Operations

Marimaca Copper operates as a single-segment exploration and development company, with its business activities centered on mineral exploration, resource delineation, and project advancement. The company does not generate operating revenue and is funded primarily through equity financings. Its operational focus is the systematic drilling, metallurgical testing, and technical studies required to advance its copper assets toward potential feasibility and permitting stages.

The company’s operations are conducted entirely in Chile, where it holds a 100% interest in its core mining concessions, subject to standard royalties. Marimaca Copper controls exploration data, geological models, and technical studies related to its projects and works with specialized contractors for drilling, engineering, and environmental services. Data inconclusive based on available public sources regarding any material joint ventures or producing subsidiaries.

Strategic Position & Investments

Marimaca Copper’s strategic direction centers on expanding and upgrading its copper resource base while de-risking the Marimaca Oxide Deposit through technical studies and metallurgical optimization. Growth initiatives include step-out drilling, resource expansion at depth and along strike, and evaluation of potential sulphide mineralization beneath the oxide horizon. The company has publicly positioned the project as having potential scalability and long-term optionality within the copper development pipeline.

The company has not disclosed any major corporate acquisitions or diversified portfolio investments outside its Chilean asset base. Its investment strategy is primarily organic, focused on reinvesting capital into exploration and development activities. Marimaca Copper has highlighted copper’s role in electrification and decarbonization trends as a macroeconomic driver supporting its long-term strategy, though this represents market context rather than operational diversification.

Geographic Footprint

Marimaca Copper’s activities are concentrated in Northern Chile, specifically within the Antofagasta Region, a globally significant copper mining district. The company’s flagship project is located near established infrastructure, including highways, ports, power supply, and operating mines, which is viewed as a strategic advantage for potential future development.

Corporate headquarters and administrative functions are based in Canada, while all field operations, exploration programs, and local stakeholder engagement occur in Chile. The company does not report operations, investments, or material assets in other geographic regions beyond these two countries.

Leadership & Governance

Marimaca Copper is led by an executive team with experience in mineral exploration, project development, and capital markets, particularly in Latin America. Leadership emphasizes technical rigor, disciplined capital allocation, and systematic de-risking of mineral assets as the company advances toward development-stage milestones.

Key executives include:

• Hayden Locke – President & Chief Executive Officer
• Ross Sinclair – Vice President, Exploration
• Gavin Latta – Vice President, Corporate Development
• Alison Carruthers – Chief Financial Officer

The company is governed by a board of directors that includes mining industry professionals and capital markets participants, with oversight focused on regulatory compliance, project advancement, and shareholder alignment.
