Cerro Chacón’s High-Grade Assays Raise Stakes Ahead of First Drilling

Exploration Breakthrough at Cerro Chacón

Piche Resources Limited (ASX – PR2) has delivered a promising update from its Cerro Chacón Gold-Silver Project in southern Argentina, reporting high-grade rock-chip assay results that reinforce the potential of this emerging epithermal system. The latest sampling, focused on quartz veins and breccia zones at the Toro Hosco and Chacón Grid prospects, returned gold grades as high as 16.98 grams per tonne and silver concentrations reaching 761.3 grams per tonne.

These results not only confirm the presence of significant mineralisation but also extend the known footprint of the system along a 14-kilometre prospective structural corridor. The assays highlight multiple silver and base-metal-rich breccia zones, indicative of a robust low-sulphidation epithermal environment similar to well-known Patagonian deposits such as Cerro Vanguardia and Cerro Negro.

Strategic Implications and Upcoming Drilling

Importantly, the new data have identified several priority drill targets, now integrated into Piche’s planned reverse circulation (RC) drilling program scheduled to commence in October 2025. This next phase aims to test the continuity of gold and silver mineralisation both along strike and at depth, a critical step toward defining a potential resource.

Alongside drilling, Piche intends to extend surface sampling further along the north-west structural trend and continue detailed structural mapping to refine the geometry and continuity of the mineralised veins. This integrated approach reflects a methodical progression from reconnaissance sampling to targeted exploration, enhancing the likelihood of delineating economically viable mineralisation.

Context Within the Region

The Cerro Chacón Project is situated within the Deseado Massif, a prolific Jurassic volcanic belt known for hosting significant gold and silver deposits. The mineralisation style, banded quartz-adularia veins and hydrothermal breccias with strong silica-clay alteration, is consistent with other successful operations in the region, lending further credibility to Piche’s exploration model.

While no drilling has been completed to date, the company’s systematic surface sampling and geochemical surveys have laid a solid foundation for the upcoming drill campaign. The results reported are based on industry-standard assay techniques and quality controls, providing confidence in the data’s reliability.

Looking Ahead

As Piche Resources moves toward its first drilling program at Cerro Chacón, the market will be watching closely for confirmation of mineralisation continuity and grade at depth. The combination of high-grade surface results and a well-defined structural corridor positions the project as a compelling exploration story in Argentina’s gold-silver sector.
