Studies & Findings

Technical studies and certified results across silver, polymetallic, and lithium resources within Pasto Grande Group concessions in Puno, Peru.
  • All our studies and results are certified by Certimin, ensuring accuracy, reliability, and compliance with industry standards for mineral analysis and exploration.

Silver & Polymetallic Findings

Feasibility work confirms a strong silver signature across key targets, supported by polymetallic associations typical of Andean Ag–Pb–Zn systems. Sampling and selective intervals have returned silver values of up to 82 oz per ton, indicating zones with high-grade potential and the opportunity to prioritize follow-up drilling and resource definition.

Geological mapping and structural interpretations delineate mineralized corridors where silver occurs with lead and zinc, with copper and molybdenum locally present. These relationships are consistent with epithermal to transitional settings in high-Andean terrains, where breccias, veining, and alteration halos can concentrate precious metals alongside base metals.

The current work program focuses on tightening drill spacing in the most prospective shoots, advancing metallurgical testwork to optimize recoveries, and expanding geophysical coverage to refine targets at depth. As results are integrated, Pasto Grande Group will prioritize conversion of the most advanced zones to compliant resources and define a development path that balances grade, tonnage, and access logistics.

Social & Environmental Responsibility

We have established agreements with local communities in the project’s area of influence. Our commitments include:

• Land-use agreements for surface rights
• Community workshops and social development projects
• Environmental protection programs

Environmental Considerations

• Studies confirm that no protected plant or animal species are at risk from our operations.
• Sustainable practices ensure minimal ecological impact.

Lithium Concentration & Estimated Reserves

Exploration studies have identified high lithium concentrations in the surrounding areas of Laguna de Loriscota. The region, located in a glacial valley, contains large deposits of lithium-rich brines and rock formations.

Surface & Depth Findings

• Surface lithium concentrations: 13.8 – 44.7 ppm
• At 60 m depth: 400 – 750 ppm

Probable Reserves

• Brine deposits: 2,000 – 3,500 ppm
• Total lithium brine resource: 4M metric tons
• Lithium rock resource: 6M metric tons

These discoveries position Pasto Grande Group among the most important lithium deposits in southern Peru.

Presence of Rare Earth Elements

In addition to our specialization in silver, gold, and lithium, Pasto Grande Group has identified rare earth elements in some concessions.

Strategic elements — including neodymium, dysprosium, lanthanum, and cerium — are vital to technology, renewable energy, and aerospace sectors.

Our team is assessing the potential of these deposits for sustainable utilization, aligning with global demand and supporting diversification.
