Kate Silver Deposit Shows Expanding Mineralization Corridor: Viscount Mining's 2025 Exploration Breakthrough

Strong Geochemical Data Confirms Continuous Silver System with Open Extensions

Viscount Mining Corp. (TSXV: VML) has completed its 2025 soil-geochemistry survey at the Kate Silver Deposit in Colorado’s Custer County, revealing compelling evidence that the known epithermal silver resource extends well beyond its current mapped boundaries. The comprehensive 549-sample MMI survey across 1800 square feet has delineated a robust and continuous silver-in-soil anomaly that traces a distinct north-south mineral corridor, suggesting the deposit remains open to further expansion in multiple directions.

The geochemical findings, when combined with structural mapping, historical drilling records, and recent airborne imagery, paint a cohesive picture of a substantial near-surface epithermal silver system. This interpretation fundamentally strengthens the case for a much larger mineralized system than currently captured in the NI 43-101 mineral resource estimate.

Understanding Viscount’s Exploration Definition: Building Silver Assets Through Systematic Geological Investigation

Viscount Mining functions as a mineral exploration company and project generator specializing in high-quality silver, gold, and copper assets across the Western United States. This definition encompasses not merely drilling and sampling, but a comprehensive approach to identifying, evaluating, and advancing economically viable mineral properties through rigorous scientific methodology and strategic partnerships. The company’s work at Kate exemplifies this philosophy, layering multiple data streams to build increasingly accurate geological models.

Multi-Directional Expansion Targets Identified Along Known Structures

Three primary mineralized zones now command attention as near-surface expansion targets. The Kate North and Kate Northeast areas extend the known silver anomaly along favorable structural trends, with historical drilling from previous operators confirming multiple multi-ounce silver intercepts. To the west, the Ben West structural alignment—a northeast-trending feature—has similarly returned significant historical silver assays, suggesting either a separate mineralized center or a connected extension of the Kate system proper. Collectively, these zones form a high-priority cluster of exploration targets with immediate drilling potential.

The northern extensions remain particularly promising, as structural continuity suggests the mineralized system could extend significantly beyond current resource boundaries. The alignment of the anomaly with known epithermal features indicates a system of genuine scale.

Historical Drilling Performance Demonstrates Robust Grade Continuity

Viscount’s own drilling campaigns across six phases have yielded 54 drill holes, of which 25 intersected intervals exceeding 110 g/t silver—a particularly encouraging result. More significantly, 10 drill holes recorded intervals surpassing 400 g/t silver, indicating grade zones of genuine economic interest within the broader mineralized envelope. These results provide a strong foundation for targeting similar high-grade zones within the expanded exploration model.

Silver Price Environment Reshapes Economic Parameters

The original Kate resource estimate assumed a silver price of US$24 per ounce. Given the substantially elevated silver prices now prevailing in global markets, Viscount expects that updated cut-off grade assumptions may unlock additional mineral inventory within the same physical footprint. While no formal resource recalculation has been completed, this price appreciation creates a compelling case for comprehensive technical reassessment. The 2025 geochemical work, combined with prior drilling success, provides the geological foundation for such an updated assessment.

2026 Exploration Program Targets Systematic Resource Growth

Viscount is now synthesizing 2025 soil data with 2022–2023 drilling results, structural interpretations, and historical information into refined 3D geological models. The planned 2026 drill program encompasses 10 drill holes totaling 500 to 750 meters, with specific objectives including:

• Step-out drilling to test expansion at Kate North and Kate Northeast
• Testing of the Ben West structural zone
• Infill drilling within the established resource envelope to support technical work and potential NI 43-101 updates

Permitting activities for the 2026 program are currently advancing, with operations expected to commence within planned timelines.

Complementary Projects Diversify Portfolio Risk

Beyond Kate, Viscount’s portfolio includes the Passiflora Porphyry Target at the same Silver Cliff property, where recent drilling intersected 843.9 meters of continuous copper-gold mineralization interpreted as peripheral to a potentially larger intrusive center. The company also controls the Cherry Creek multi-metal district in Nevada, comprising 236 total claims across a historically productive mining region with documented silver-gold veins, carbonate-replacement deposits, and porphyry-related systems.

Technical Validation and Forward Direction

The geochemical survey results have been reviewed and approved by Harald Hoegberg CPG, an independent consulting geologist and Qualified Person under NI 43-101, validating the technical interpretations. The coherent nature of the silver anomaly, combined with structural evidence and historical drilling performance, establishes a credible framework for the 2026 drill program targeting expansion mineralization along a continuous north-south trend that remains geologically open in multiple directions.
