Patriot Resources Unveils 774Moz Silver Target at Tassa Project

Patriot Resources Unveils Massive 774-559 Moz AgEq Exploration Target at Tassa

Patriot Resources unveils Tassa silver project with a stunning upgrade that positions the company among the largest undeveloped silver systems globally. The company has announced an independently prepared JORC-compliant Exploration Target of 774 Moz-559 Moz Silver Equivalent from 422-359 Mt ore at 57-48 g/t AgEq, marking a transformational step-change for the Southern Peru project.

The updated Exploration Target represents a district-scale silver system built on more than 20 years of geological data integration. This extensive dataset comprises 1,832 surface samples, 8,500m of diamond drilling, ~36kms of IP geophysics and ~70km of magnetics lines, providing unprecedented confidence in the geological understanding and targeting approach.

Understanding Exploration Targets: What Investors Need to Know

An Exploration Target represents conceptual areas where geological evidence suggests potential for mineralisation, but insufficient exploration has been completed to estimate a Mineral Resource. Unlike a Mineral Resource, which has defined confidence levels, an Exploration Target indicates the scale of opportunity based on integrated geological interpretation.

For investors, Exploration Targets are significant because they demonstrate scale potential beyond current resources. Furthermore, they guide drilling priorities for resource conversion whilst providing upside scenarios for valuation models. In addition, they indicate systematic exploration approach.

The key factor distinguishing Tassa's Exploration Target is that it draws upon 20+ years of multi-source datasets from three separate operators. This substantially reduces geological uncertainty compared to purely conceptual targets. Consequently, this historical validation provides exceptional confidence in the geological model and targeting methodology.

Exceptional High-Grade Surface Intercepts Validate System Quality

The Exploration Target builds upon remarkable surface sampling results consistently reproduced across a 19-year sampling interval by three independent operators. These results demonstrate the exceptional quality and consistency of the mineralised system.

Peak Silver Results:
• 8,160 g/t Ag – rock chip sample (Bear Creek, 2011)
• 1,090 g/t Ag with 0.09 g/t Au – channel sample (Bear Creek, 2010)
• 950 g/t Ag – rock sample (TeckCominco, 2006)
• 890 g/t Ag with 3,212 ppm Cu – channel sample (Buena Vista, 2025)

Polymetallic Credits Demonstrate System Richness:
• 5.36 g/t Au – sample 38532 (Bear Creek, 2011)
• 4.40 g/t Au with 724 ppm Pb – sample 65124 (Buena Vista, 2025)
• 2.44 g/t Au, 252 g/t Ag and 0.55% Cu – sample 38486 (Bear Creek, 2011)
• 2.62% Zn and 1.79% Pb – sample 51008162 (Teck, 2023)

Out of all surface samples collected, 577 samples recorded silver concentrations above 10g/t Ag. Meanwhile, 82 samples showed gold concentrations exceeding 0.1 g/t Au. This breadth of high-grade results across multiple sampling campaigns provides strong validation of the system's mineralisation potential.

Drilling Results Confirm System Depth and Continuity

Historical drilling across 26 diamond holes totaling 8,474.5m has established significant intercepts within three clustered zones. However, this confirms both the depth extent and continuity of mineralisation.

Critical Growth Indicators: End-of-hole assays in three drill holes confirm the system remains open at depth:
• Drillhole T-01: 26m at 25.38 g/t Ag from 226m to EOH
• Drillhole T-04: 3m at 29.5 g/t Ag from 206m to EOH
• Drillhole T-20: 5.6m at 49.5 g/t Ag from 147m to EOH

These end-of-hole intercepts demonstrate that mineralisation continues beyond current drilling depths. For instance, this provides additional confidence in the expansion potential of the system.

Geophysical Surveys Define Target Geometry

Comprehensive geophysical surveys covering 35.8 kilometres of IP lines and 70.35 kilometres of magnetic lines have identified two main chargeability anomalies. These correlate strongly with known mineralisation.

Anomaly 1: Located between lines L300S and L500N
• Maximum values of 37 mV/V
• Open to the south and southeast
• Interpreted as disseminated sulfides with moderate clay alteration

Anomaly 2: Situated between lines L300N and L2100N
• Maximum values of 25 mV/V
• Strong correlation with surface geochemical anomalies

The critical factor for development potential is that IP chargeability anomalies begin at or near surface and extend to 550m depth. This near-surface profile is consistent with large-scale, open-pit mining scenarios. Furthermore, it potentially reduces the capital intensity and technical risk associated with underground operations.

What Makes This a District-Scale Discovery?

The updated Exploration Target encompasses 19 mineralised zones across a 2.9 km strike length and ~1.0 km width. This demonstrates the genuine district-scale nature of the mineralised system.

Key Geological Features:
• Surface-dominant silver system with full exposure to silver prices
• Polymetallic credits from high-grade copper, lead, zinc, and gold
• Structural controls via NW-SE and N-S fault systems
• Epithermal characteristics consistent with large-scale development

The identification of 19 modelled zones demonstrates potential for further discoveries and expansion beyond the current Exploration Target envelope. In addition, this systematic approach to zone delineation provides clear drilling targets for future resource conversion programmes.

Clear Path to Resource Conversion and Value Creation

Patriot Resources unveils Tassa silver project progression through a focused strategy designed to convert Exploration Target material into JORC Mineral Resources. This occurs through systematic drilling and community engagement.

Immediate Priorities:
• 4,000m infill drilling programme targeting high-confidence "bridge zones"
• Community engagement and permitting (currently underway)
• Systematic testing of 19 defined target zones
• Continuous integration of drill data to optimise subsequent phases

"This Exploration Target marks a step-change in how we understand the scale of Tassa. 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," commented CEO Dominic Duggan.

Strategic Development Pathway:
• Technical studies progression alongside exploration success
• JV and strategic partnership evaluation
• Resource growth trajectory through systematic drilling
• District-scale expansion potential

Why the Bridge Zone Strategy Matters

The bridge zone strategy focuses on areas between known high-grade intersections where geological confidence is highest. This approach maximises the probability of converting Exploration Target material to Mineral Resources. Furthermore, it provides clear drill targeting for immediate value creation.

These bridge zones represent the most cost-effective pathway to resource growth. However, they also establish a foundation for broader systematic drilling across the 19 mineralised zones identified within the target envelope.

Investment Thesis: Why Tassa Demands Attention

Patriot Resources unveils Tassa silver project with characteristics that distinguish it from typical exploration plays. Several factors position Tassa as a genuinely district-scale silver discovery with exceptional development potential.

Data Quality and Validation

The 20+ years of multi-operator datasets provide exceptional geological confidence. Moreover, independent validation by Teck, Bear Creek, and Buena Vista across different market cycles demonstrates consistent system quality. The JORC-compliant methodology with independent technical review further strengthens investor confidence.

Scale and Quality Combination

The 774-559 Moz AgEq places Tassa among globally significant undeveloped silver systems. The high-grade silver-dominant system at surface reduces technical risk. In addition, polymetallic credits provide revenue diversification and margin enhancement.

Favourable Development Characteristics

The near-surface geometry (400-550m depth) supports open-pit development scenarios. The 2.9 km strike length indicates long-life mining potential. Furthermore, established infrastructure in Southern Peru mining region provides logistical advantages.

Clear Value Catalysts

The drill-ready status with 4,000m programme targeting immediate resource growth provides near-term catalysts. Bridge zones between existing resources offer high-confidence conversion targets. However, 19 defined zones provide systematic exploration pipeline for sustained growth.

Jurisdictional Advantages

Peru's established mining jurisdiction provides clear regulatory frameworks. The strategic location in active mining district offers infrastructure access. Moreover, definitive mining titles covering 1,200 hectares secure tenure over the entire system.

Why Investors Should Follow Patriot Resources

Patriot Resources has demonstrated technical capability that distinguishes it from many junior explorers through its systematic approach. The company's ability to integrate decades of historical data into a coherent geological model showcases methodical development. For instance, institutional investors increasingly seek this approach.

Key Tracking Points:

The scale of the Exploration Target, combined with the quality of the underlying dataset, positions Tassa favourably. Furthermore, the clear pathway to resource conversion establishes it as a potential tier-one silver development project. In a market where large-scale, high-grade silver systems are increasingly rare, Patriot Resources unveils Tassa silver project as a compelling opportunity.

With systematic drilling about to commence and multiple value catalysts on the horizon, Patriot Resources represents exceptional potential. However, investors should recognise that this opportunity combines exposure to silver's structural growth drivers with a high-quality, advanced exploration asset in an established mining jurisdiction.
