Marimaca Copper Corp. Expands Pampa Medina Project with High-Grade Copper Discoveries

Marimaca Copper Corp. has unveiled significant drilling results from its Pampa Medina project, indicating a promising expansion of the copper deposit. The recent drilling activities, particularly Hole SMD-03, demonstrate the presence of high-grade sediment-hosted copper sulphide and oxide intersections. Notably, this hole reveals a substantial 56 meters of ore with an average grade of 2.1% copper, which includes an exceptional 18 meters at 5.0% copper. Additionally, a broader section of 102 meters averages 1.2% copper, showcasing the project's potential for higher-grade mineralization. Another drill hole in the series identifies 42 meters of mineralization with a grade of 0.72% copper, further confirming the region's rich geological profile.

The geological characteristics of the Pampa Medina project highlight a primary sedimentary manto that spans an extensive area of approximately 600 meters by 1,000 meters, consistently yielding high-grade copper readings above 1% copper. The deposit's flat-lying structure, characterized by gentle dips and plunges, aligns well with the north-south faulting observed in the area. This geological setting not only enhances the project's potential but also suggests a straightforward extraction process due to the favorable orientation of the ore bodies. Marimaca Copper's strategic focus on this location reinforces its commitment to developing a viable mining operation in a region known for its rich copper resources.

In addition to geological advantages, the Pampa Medina project benefits from its proximity to established mining operations. Situated just 28 kilometers from MOD, 64 kilometers from Sierraorda, and 40 kilometers from Mantos Blancos, the site leverages existing infrastructure, including powerlines and water pipelines. This accessibility not only facilitates operational efficiency but also minimizes logistical challenges. Moreover, the flat, low-altitude terrain provides ample space for future facilities, while the area's low permitting risks—attributed to the absence of private land ownership and limited human impact—further enhance the project's feasibility.

In light of these encouraging drilling results, Marimaca Copper Corp. announces a pause on its previously planned Preliminary Economic Assessment. The company aims to reassess the implications of these discoveries on the potential scale and economic viability of the Pampa Medina project, reflecting a prudent approach to resource development in the competitive copper market.

Marimaca Copper Corp. continues to advance its exploration efforts, with these new findings positioning the company favorably within the copper industry. The combination of high-grade mineralization and strategic geographic advantages underscores the project's potential to make a significant impact in the global copper supply chain. As the company reevaluates its development strategy, stakeholders remain optimistic about the future of the Pampa Medina project.
