VISCOUNT REINFORCES SILVER EXPANSION POTENTIAL AT THE KATE DEPOSIT WITH CONTINUOUS SILVER CORRIDOR

Viscount Mining Corp. has provided an updated interpretation of the 2025 soil geochemistry program at the Kate silver deposit, part of the company's 100-per-cent-owned Silver Cliff project in Custer county, Colorado. When integrated with historical and recent drilling, structural mapping and prior geophysical survey, the results reinforce Kate as a robust, near-surface epithermal silver system with multiple priority expansion targets.

Kate silver deposit -- strong silver anomaly

The 2025 MMI soil geochemistry program (549 samples) covering an area of 1,800 square feet defined a coherent and highly developed silver-in-soil anomaly centred directly on the Kate deposit. This anomaly forms a distinct north-south corridor extending into the Kate North and Kate Northeast target areas, and aligns closely with the structural fabric of the known epithermal system. The strength and continuity of the anomaly support the interpretation that silver mineralization extends beyond the current National Instrument 43-101 resource footprint.

Interpretation -- strong epithermal silver system along a continuous trend

Integration of soil geochemistry, structural data, historical drilling and prior airborne imagery confirms that Kate hosts a strong epithermal silver system tied directly to the known resource. Mineralization appears to extend along a continuous north-south trend that remains open to the north-northeast. These characteristics are consistent with a larger, near-surface system and provide good guidance for the coming drill program.

Silver expansion potential

The Kate deposit is a shallow, silver-rich epithermal system that hosts the current National Instrument 43-101 mineral resource based on a $24-(U.S.)-per-ounce silver price. With silver prices substantially higher than when the resource was estimated, the company believes there may be potential -- pending future drilling and a 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 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 that occur along the structural extensions near the Jay Gould breccia pipes, indicating the system remains open.

To the west, the Ben West alignment returned historical multiounce silver intercepts along a northeast-trending structure. This may represent a separate mineralized centre or an extension of the Kate system. These zones collectively define a cluster of high-priority near-surface targets.

Viscount past drill highlights

Throughout these 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.

2026 drill program planning

Viscount is integrating the 2025 soil geochemistry results with its 2022-2023 drilling data, structural mapping, historic drill information and airborne imagery into updated 3-D geological models. The 2026 drill program is expected to include 10 drill holes over a total distance of 500 metres to 750 metres:

• Stepout drilling at Kate North;
• Stepout drilling at Kate Northeast;
• Drill testing of the Ben West structural corridor;
• Infill drilling within the existing resource envelope to support future technical work and revised NI 43-101.

Permitting for the 2026 drill program is under way.
