#Marimaca Copper Reports High-Grade Silver Assays

Marimaca Copper Corp., a Canadian mining company, announced significant results from its ongoing exploration at the Pampa Medina deposit, located in the Antofagasta region of Chile. The latest silver assay results, released on April 2, 2026, demonstrate a consistent correlation of elevated silver grades with copper concentrations, further validating the company’s exploration hypothesis.

#Pampa Medina Deposit Overview

The Pampa Medina deposit is situated approximately 28 kilometers east of Marimaca's flagship Marimaca Oxide Deposit. The project's geology characterizes it as a manto-style copper deposit, primarily hosted within sedimentary units dating back to the Jurassic and Triassic periods. This complex geological setting, combined with its strategic location, positions Pampa Medina as a significant prospect within the region.

#Drilling Insights and Future Plans

Marimaca's release includes a comprehensive consolidation of drilling results from Pampa Medina, emphasizing the consistent high-grade mineralization across a 3-kilometer by 2-kilometer area. As drilling continues, the company aims to delineate high-grade zones while exploring potential extensions to the west, northwest, and northeast. Current operations involve five drilling rigs, with plans to increase this number in the coming months.

#Geological Features and Assaying Procedures

The ongoing drilling has revealed copper mineralization featuring atacamite, chrysocolla, and significant zones of bornite and chalcopyrite. The presence of silver as a by-product enhances the project's attractiveness, as similar deposits in the region have shown profitable returns through silver, including notable nearby operations such as Mantos Blancos and Cachorro.

Assays have been conducted using a rigorous quality assurance program, ensuring reliable sampling and analysis of both silver and copper contents. The full metallurgical studies are still pending, and the company has refrained from reporting copper equivalent grades at this time.

#Strategic Exploration and Market Positioning

The ongoing exploration effort at Marimaca reflects the company's commitment to uncovering the full potential of its resources. The positive assay outcomes signal a promising future for the Pampa Medina project, particularly as silver by-products can significantly enhance the economic viability of large-scale copper mining operations.

#Key Takeaways

  • Marimaca Copper has reported high-grade silver assays from the Pampa Medina deposit in Chile.
  • The silver grades show a strong correlation with copper mineralization, emphasizing the potential economic benefits.
  • The company plans to increase its drilling rig count to accelerate its exploration program.
  • Pampa Medina’s geology features complex sedimentary units, contributing to its high-grade mineral deposits.
  • The project aligns well with industry trends, where silver by-products augment the value of copper mining ventures.
