VISCOUNT COMMENCES DRILLING AT THE KATE SILVER DEPOSIT IN SILVER CLIFF, COLORADO

Viscount Mining Corp. has begun drilling at the Kate silver deposit, within its 100-per-cent-owned Silver Cliff project in Custer county, Colorado. The Kate deposit is a robust, near-surface epithermal silver system with multiple priority expansion targets. The 2026 drill program is designed to expand the existing NI 43-101 resource and test high-priority targets that may materially extend mineralization beyond the current model, both laterally and at depth.

Management believes the Kate deposit represents a significantly underexplored silver system that remains open in multiple directions and at depth, with the potential to support meaningful resource growth as part of an updated NI 43-101 estimate targeted for completion later this year. The company believes this program represents a key catalyst for redefining the scale of mineralization at Silver Cliff.

Silver expansion potential

The Kate deposit is a shallow, silver-rich epithermal system that hosts the most recent NI 43-101 mineral resource based on a $24-(U.S.)-per-ounce silver price. With silver prices now substantially higher than when the resource was estimated, the company believes there may be potential -- pending future drilling and NI 43-101 review -- to re-examine cut-off assumptions as part of a future technical update. No new resource estimate or economic analysis has been completed.

The Kate deposit has historically been the cornerstone of silver mineralization within the district. However, recent drilling, geological reinterpretation and geophysical analysis suggest that the mineralized system may extend materially beyond the limits of the current resource model. The 2025 geochemical survey, combined with historical drilling, highlights expansion potential to the north and northeast. Historical drilling by previous operators returned numerous multiounce silver intercepts occur along the structural extensions near the Jay Gould breccia pipe, indicating the system remains open.

To the northwest, the Ben West alignment returned historical multiounce silver intercepts along a northwest-trending structure, as well as strong surface sample assays. This may represent a separate mineralized center or an extension of the Kate system. These zones collectively define a cluster of high-priority near-surface targets.

Historical drilling by previous operators returned numerous multiounce silver intercepts occur along the structural extensions near the Jay Gould breccia pipe, indicating the system remains open.

The company's most recent NI 43-101-compliant resource at the Kate deposit comprises approximately 24 million ounces of silver across measured, indicated and inferred categories. This represents a near-surface, drill-defined system with demonstrated continuity. While this resource establishes a solid base, management believes that it does not yet fully reflect the scale potential of mineralization within the broader Kate deposit.

The Kate hosts a NI 43-101 completed (April, 2023) compliant near-surface silver resource published by an independent QP (details: Measured and indicated and inferred silver resources were reported in the company's technical disclosure; investors are encouraged to review the full technical report available on SEDAR+ for tonnage, grade and methodology).

2026 drill program

Viscount is integrating 2025 soil-geochemistry results with its 2022-2023 drilling data, geologic mapping, historic drill information and airborne imagery into updated 3-D geological models. The 2026 drill program is a 10-hole, 1,000-metre drill program designed to expand the current mineralized footprint and provide additional data required for a revised NI 43-101 resource later this year. The upcoming drill program has been strategically designed to both extend known zones of mineralization and test deeper targets interpreted as potential feeder pathways for mineralizing fluids. Recent geochemical work has highlighted several priority targets beneath the Kate area, which may represent key structural controls on the system. Several planned drill holes will test these deeper zones to evaluate whether mineralization strengthens, widens or evolves.

The company believes this drill program has the potential to materially enhance the overall scale, continuity and confidence of mineralization at Silver Cliff, while further demonstrating the presence of a large, district-scale silver system. Management views this program as a critical inflection point in advancing the project toward a more comprehensive understanding of its full potential.

Results from this program are expected to play a significant role in supporting the next stage of resource expansion at the Kate deposit and will form a key component of the company's updated NI 43-101 resource later this year.

• Step-out drilling at Kate North and South;

• Step-out drilling at Kate Northeast;

• Drill testing of the Ben West structural trend;

• Infill drilling within the existing resource envelope.

Viscount past drill highlights

Throughout six drilling campaigns performed at the Kate, 54 drill holes were drilled by Viscount. Of these, 25 drill holes presented intervals assaying greater than 110 grams per tonne and 10 drill holes displaying intervals assaying over 400 g/t.
