Patriot Resources Validates Tassa Silver-Gold Data Integrity Ahead of Drilling

Independent Re-Assays Confirm Historical Grade Accuracy

Patriot Resources Limited (ASX:PAT) has taken a crucial step in de-risking its flagship Tassa Silver-Gold Project by independently re-assaying 46 samples from seven historical drill holes. The results demonstrate a strong correlation with grades originally reported by previous operators Teck and Bear Creek Mining, effectively validating over two decades of inherited geological data underpinning the project's 31.4 million ounce silver equivalent (AgEq) inferred resource at 52.68 g/t AgEq.

The re-assay program employed industry-standard multi-element acid digestion and fire assay techniques consistent with those used historically, with high-grade samples further analysed for precision. Minor variances in some Southern Zone samples fall within expected local variability, including nugget effects common in epithermal deposits. This independent verification provides a solid foundation for Patriot’s upcoming maiden drill campaign, aimed at both infill and resource expansion.

Environmental and Community Approvals Strengthen Development Pathway

Regulatory progress at Tassa has also advanced with Peru’s Ministry of Mining (MINEM) confirming the validity of the project's Environmental Impact Declaration (DIA) without any technical observations. This clearance removes a significant procedural hurdle, enabling Patriot to move confidently towards drilling.

On the social front, board-level engagement has been a highlight, with Managing Director Dominic Duggan and Non-Executive Director Diego Cillóniz meeting directly with the Tassa Community’s Governing Committee. Their visit included participation in a community ceremony and discussions on land use agreements, signaling Patriot’s commitment to securing the critical social licence necessary for exploration activities.

Tassa Project’s Scale and Exploration Potential

The Tassa project hosts a maiden JORC (2012) inferred mineral resource of 31.4Moz AgEq from 18.53 million tonnes at 52.68 g/t AgEq, open in all directions. The mineralised corridor stretches approximately 2.9km along strike, 1.0km wide, and extends to depths of about 550m. An exploration target of 559-774Moz AgEq across 19 mineralised zones remains conceptual but highlights the scale of potential upside.

Patriot currently holds 8,500m of historical diamond drill core at its Arequipa facility, providing valuable data for ongoing analysis. The company plans a ~4,000m infill and expansion drilling program to convert the exploration target into a formal resource, targeting zones with strong silver dominance in the North and Central areas and gold focus in the Southern zone.

Technical Rigor Underpins Resource Confidence

The re-assay results align closely with historical datasets, with coefficients of determination near unity for silver and gold grades. This level of correlation supports the reliability of the inherited data and the geological model's robustness. The sampling and assaying adhered to strict quality control protocols, including the use of certified reference materials and blanks, with approximately 10% of samples dedicated to QA/QC checks.

Geological logging, drill core recovery, and sample security measures meet industry best practices, and the data has been rigorously validated. The inferred resource estimate employs ordinary kriging with spatial continuity parameters appropriate for the deposit style and includes top-cutting of outliers to manage grade extremes.

Next Steps: Drilling and Community Agreement

With environmental approvals confirmed and community relations progressing through direct board engagement, Patriot is positioning itself to commence its maiden drill program at Tassa. The upcoming campaign will focus on both infill drilling to upgrade the resource category and step-out drilling to test the extensive exploration target.

Investor attention will likely turn to drill results that can substantiate the exploration target’s potential and pave the way for resource growth. Meanwhile, securing a formal community agreement remains a pivotal milestone for operational advancement in Peru’s Moquegua region, a jurisdiction known for its significant silver reserves and mining infrastructure.
