Overview
Diablillos is a high sulfidation silver-gold & copper-gold porphyry intrusive at depth project, located in the Puna region of the Province of Salta, Argentina and is operated by AbraSilver Resource Corp. (AbraSilver).
There are currently several known mineralized zones on the Diablillos property, with the Oculto zone being the most important and the most explored. Oculto is a deeply oxidized, high-sulfidation epithermal silver-gold deposit. Recent surface mapping and drill data interpretation indicates that high grade mineralization at Oculto is strongly correlated with steeply dipping, tabular, hydrothermal breccia bodies oriented along northeast-trending faults. Recent drilling confirmed that these hydrothermal breccias continue into the basement and identified high-grade copper intercepts up to 5% Cu, suggesting the potential for deeper porphyry-style mineralization.
Close-range, nearer-term targets at Diablillos include Oculto, Fantasma, Laderas, and Alpaca. Most of the longer-term distal targets, except for Yolanda, are aligned along a curving trend and are collectively known as the Northern Arc zones. These zones include the Cerro Viejo Este and Oeste, the Cerro del Medio Norte, Pedernales, and Corderos. This group of prospects lies approximately 3-4km north-northeast of the center of the Oculto deposit. All encompass epithermal silver-gold targets similar in style to Oculto, and one, Cerro Viejo, shows potential for porphyry mineralization.
AbraSilver published a Pre-Feasibility Study in Q1 2025 and an updated Mineral Resource Estimate for the Diablillos project in 2025.
