Gollete Project Background

GOLLETE PROJECT
Indio Belt, San Juan

Concealed High-Sulphidation Gold System

A fully concealed, CSAMT-ready drill target with strong vuggy-silica floats (up to 100 g/t Ag, 0.13 g/t Au) and environmental drill permit already approved. Gollete stands out for its scale, preservation, and proximity to world-class deposits.

Gollete Project Overview

World-Class Scale & Geological Validation

Detailed mapping confirms that Gollete's advanced argillic alteration system is comparable in size to major world-class deposits in the Indio and Maricunga Belts. This supports the project's potential to host a significant, concealed gold resource.

The scale and preservation of Gollete validate its status as a premier exploration target in the region.
