Patriot Resources Ltd. has announced a massive upgrade to the exploration target of its Tassa silver and gold project in Southern Peru, positioning the asset as one of the largest undeveloped silver systems globally.
The company revealed a new independent JORC-compliant Exploration Target of between 559 million and 774 million ounces of silver equivalent (AgEq). This massive scale-up is based on an estimated 359 to 422 million tonnes of ore, with grades ranging from 48 to 57 g/t AgEq.
The upgrade follows the first-ever integrated analysis of two decades of geological data, including over 1,800 surface samples, 8,500 metres of diamond drilling, and extensive geophysical surveys.
Patriot’s Managing Director and CEO, Dominic Duggan, described the update as a step-change for understanding the scale of Tassa.
“Defining up to 774Moz AgEq clearly demonstrates that the current resource footprint represents only a small part of a much larger mineralised system,” Duggan said.
“What is particularly compelling is the quality—a silver-dominant system at surface with clear potential to support large-scale, open-pit development.
“These are the characteristics that are increasingly difficult to find and are actively sought by mid-tier and major producers.”
The Tassa project has shown exceptional high-grade results at surface, with peak rock chip samples previously hitting as high as 8,160 g/t silver.
The system also boasts significant polymetallic potential, with gold, copper, and zinc credits identified across 19 different mineralised zones.
With mineralisation already defined over a nearly three kilometre strike and up to 550m in depth, the company believes Tassa is emerging as a district-scale asset.
Patriot is now moving swiftly toward the execution phase. Permitting is currently underway for a focused 4,000-metre infill drilling program designed to convert these massive exploration targets into formal mineral resources.
The company is also doing systematic testing of 19 defined target zones to validate continuity and unlock district-scale potential, as well as progressing technical studies to support potential joint ventures, partnerships or development scenarios.
