Marimaca Copper (TSX:MARI) - Big Discovery Adds High Grade & Scale

Marimaca Copper (TSX:MARI) Gains Momentum with High-Grade Discovery and Strategic Development Plan

In a recent interview with Crux Investor, Hayden Locke, President and CEO of Marimaca Copper, provided an in-depth update on the company's advancing projects in northern Chile’s prolific copper belt. The company is at a pivotal point, balancing the finalization of its Definitive Feasibility Study (DFS) for the flagship Marimaca oxide project with promising exploration results at its nearby Pampa Medina project. These developments collectively underscore Marimaca’s potential to significantly expand its resource base and production outlook.

**Current Progress and Strategic Focus**

Marimaca Copper’s flagship project, the Marimaca oxide deposit, is nearing completion of its DFS, a critical step toward advancing toward production. The company’s strategic approach involves a hub-and-spoke model, where the Marimaca oxide deposit serves as the central processing hub, complemented by satellite deposits like Pampa Medina and Madrugador. This model aims to optimize capital efficiency and streamline development, enabling the company to leverage existing infrastructure while expanding its resource footprint.

**Exploration Breakthroughs at Pampa Medina**

One of the most notable recent developments at Pampa Medina is the discovery of two stacked mineralized mantos, which could dramatically alter the project’s scale. Drill results have revealed an upper zone with approximately 80 meters intersecting over 1.2% copper, including a high-grade segment exceeding 20 meters at roughly 2.5%. Such grades are highly attractive in the copper space, promising better economic returns. Even more exciting is the evidence of substantial mineralization in the lower 300 meters, featuring visible bornite and chalcopyrite, although assays from these deeper zones are still pending.

Hayden Locke highlighted that the company believes Pampa Medina could nearly double in size if mineralization continuity extends between the current Pampa Medina manto and the Pampa Medina Norte extension. This potential expansion could significantly increase the deposit’s strike length and resource estimate, drawing parallels to Antofagasta’s Cachuro discovery, which boasts over 300 million tons at more than 1% copper.

**Implications for Production and Economics**

The exploration success at Pampa Medina and Madrugador holds the promise of elevating Marimaca’s production profile. Currently, the company's development plans aim for approximately 50,000 tons of copper annually from the flagship oxide project. However, the integration of satellite deposits could boost total annual production to between 70,000 and 75,000 tons. Such a scale would position Marimaca as a significant copper producer, potentially ranking as the sixth-largest on the ASX.

Internal assessments suggest that Madrugador and Pampa Medina alone could contribute 20,000-25,000 tons per year over a 13-14-year mine life, even without further exploration success. To validate these projections, Marimaca has commissioned an integration study from Stantec, which will analyze the economic benefits of incorporating these satellite deposits into a unified development plan.

**Metallurgical Outlook and Future Catalysts**

Initial metallurgical tests indicate promising recoveries from the Pampa Medina oxide material. Early data suggest high acid solubility and potentially superior recovery rates compared to the flagship project. This bodes well for the project's economics, especially if larger-scale extraction becomes feasible.

Looking ahead, Marimaca’s near-term catalysts include the completion of its DFS, assay results from ongoing deep drilling efforts, and the forthcoming integration study outcomes. These milestones are set against a backdrop of favorable macroeconomic fundamentals for copper, driven by rising demand from renewable energy, electric vehicles, and infrastructure development, coupled with constrained supply growth.

**Conclusion**

Marimaca Copper’s recent exploration success and strategic development approach position it as a noteworthy player in the mid-tier copper space. With a clear path toward production, an expanding resource base, and multiple catalysts on the horizon, the company is poised to benefit from the ongoing demand surge for copper. As it moves closer to realizing its development plans, investors and industry watchers will be keenly observing how the company leverages its discoveries to scale operations and unlock value.
