Cerro Chacon’s Untapped Veins Could Define Next Big Gold-Silver Discovery

Exploration Breakthrough at Cerro Chacon

Piche Resources Limited (ASX – PR2) has announced encouraging results from its latest geochemical sampling campaign at the Cerro Chacon Gold Project in southern Argentina. The company collected 243 rock chip and soil samples across two key prospects, Chacon Grid and Toro Hosco, revealing multiple high-grade gold and silver occurrences that expand the project's mineral potential.

The standout assays include gold grades reaching 15.77 grams per tonne (g/t) and silver up to 74.60 g/t, with several samples also showing elevated base metals such as lead and zinc. These results come from surface sampling only, with no drilling undertaken to date, underscoring the early-stage but promising nature of the exploration.

Distinct Mineralised Structures at Toro Hosco

At Toro Hosco, Piche identified two separate styles of mineralisation. The northern zone features breccia-hosted mineralisation with minor quartz veins, exhibiting veins up to 15 meters wide and extending 600 meters along strike. This area shows strong pathfinder geochemistry but comparatively lower gold and silver grades, suggesting it represents a higher level in the epithermal system.

Conversely, the southern Toro Hosco zone displays a dense network of quartz veins with significant gold and silver assays, indicating exposure of a deeper, potentially richer part of the system. The vein orientations and structural complexity mirror those seen in world-class epithermal deposits, hinting at substantial exploration upside.

Integrated Approach Defines New Drill Targets

Piche’s exploration strategy combines detailed surface geological mapping, multi-element geochemical analysis, and geophysical surveys. This integrated approach has successfully delineated numerous mineralised veins and breccia zones, many of which are believed to be interconnected, forming continuous strike targets ripe for drilling.

The company’s geophysical data, including magnetic and induced polarisation surveys, correlate strongly with the geochemical anomalies and structural features, providing a robust framework for upcoming drill programs. These efforts aim to test the depth and continuity of mineralisation, critical steps toward resource definition.

Looking Ahead

While the current results are surface-based and preliminary, they significantly enhance the geological understanding of Cerro Chacon and reinforce its potential as a large, low-sulphidation epithermal gold-silver system. The project’s scale and structural complexity align with other notable deposits in southern Argentina, positioning Piche well for future exploration success.

With drilling planned to follow up on these promising targets, investors and analysts will be watching closely for confirmation of subsurface mineralisation and potential resource upgrades.
