Massive upgrade to Exploration Target of 774-559 Moz AgEq at Tassa
Patriot Resources Ltd. is pleased to announce a massive upgrade to the Exploration Target for its 100%-owned high-grade Tassa Silver & Gold Project in Southern Peru of 774 Moz-559 Moz SilverEq from 422-359 Mt ore at 57-48 g/t AgEq, positioning Tassa among the largest undeveloped silver systems globally.
The updated Exploration Target has been independently prepared and is underpinned by the first integrated interpretation of more than 20 years of geological (2026-2006), geochemical and geophysical data, comprising 1,832 surface samples, 8,500m of diamond drilling, ~36kms of IP geophysics and ~70km of magnetics lines, and all reconciled with the Company’s February 2026 Maiden Inferred Mineral Resource Estimate.
Cautionary statement for Exploration Target
The Exploration Target has been prepared and reported in accordance with the 2012 edition of the JORC code. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for the target areas reported. It is uncertain if further exploration will result in the estimation of a Mineral Resource.
Patriot’s Managing Director and CEO, Dominic Duggan said:
“This Exploration Target marks a step-change in how we understand the scale of Tassa. Defining up to 774Moz AgEq from an integrated dataset built over more than 1,800 surface samples, ~36kms of IP geophysics, ~70km of magnetics lines and 8,500m of diamond drilling clearly demonstrates that the current resource footprint represents only a small part of a much larger mineralised system. What is important is that this interpretation is supported by a broad distribution of anomalous surface results that align with geophysical anomalies and extend beyond the current Mineral Resource.
What is particularly compelling is not just the size, but the quality of the opportunity – a silver-dominant system at surface, with strong continuity, and clear potential to support large-scale development. These are the characteristics that are increasingly difficult to find and are actively sought by mid-tier and major producers.
Importantly, this is not a conceptual story without foundation. The Exploration Target is underpinned by extensive historical drilling, geophysics and geochemistry, all validated through independent modelling. With this level of data confidence, our focus now shifts to execution – converting these targets into Mineral Resources through our upcoming drill program.
We believe Tassa is emerging as a genuinely district-scale silver system with the potential to deliver significant value as we move through the next phase of resource growth.”
