  • Marimaca Copper Corp. announced high-grade copper discoveries at Pampa Medina, including 56 meters averaging 2.1% copper.
  • The project's geological structure supports large-scale mining, with a high-grade copper zone extending over 600 by 1,000 meters.
  • Marimaca Copper is pausing its Preliminary Economic Assessment to reassess project implications based on recent drilling results.

Marimaca Copper Corp. Unveils High-Grade Copper Discoveries at Pampa Medina Project

Marimaca Copper Corp. has recently announced significant drilling results from its Pampa Medina project, revealing high-grade sediment-hosted copper sulphide and oxide deposits. The results from Hole SMD-03 are particularly noteworthy, as it intersects 56 meters of mineralization averaging 2.1% copper, which includes an exceptional 18 meters at 5.0% copper. Additionally, a broader 102-meter section showcases an average grade of 1.2% copper, while another drill hole uncovers 42 meters at 0.72% copper from a depth of 226 meters. These findings not only underline the richness of the deposit but also suggest a substantial extension of the mineralized area.

The geological structure at Pampa Medina demonstrates a primary sedimentary manto that consistently carries high-grade copper (greater than 1% copper) across a significant expanse of 600 meters by 1,000 meters. The area is characterized by a flat-lying geological formation with a gentle dip and plunge, influenced by north-south faulting. This configuration enhances the project’s potential for large-scale mining operations and positions Marimaca Copper favorably for further exploration and development.

Pampa Medina's geographical advantages are also notable, as it lies in close proximity to existing mining infrastructures. Located just 28 kilometers from MOD, 64 kilometers from Sierraorda, and 40 kilometers from Mantos Blancos, the site benefits from established powerlines and water pipelines that facilitate efficient operational logistics. The flat, low-altitude terrain not only provides ample space for future development but also minimizes permitting risks due to the absence of private land claims and limited human disturbance in the area. In light of these promising drilling results, Marimaca Copper has opted to pause its previously planned Preliminary Economic Assessment to reassess the implications of these discoveries for the project's overall scale.

In addition to the drilling results, the company's strategic decision to reevaluate its project assessment indicates a commitment to thorough analysis before advancing. This proactive approach signals to stakeholders the importance of leveraging new data to maximize the project's potential. As the company navigates this promising phase, it remains focused on optimizing its operational framework to capitalize on the high-quality copper found at Pampa Medina.

Overall, Marimaca Copper Corp.'s recent drilling achievements at the Pampa Medina project not only enhance its portfolio but also position it favorably within the competitive landscape of the copper mining industry. The combination of rich mineralization, advantageous location, and reduced permitting risks sets a strong foundation for future exploration and development efforts.
