Viscount Reinforces Silver Expansion Potential at the Kate Deposit with Continuous Silver Corridor

Rhea-AI Summary

Viscount Mining (OTCQB: VLMGF) reported results from a 2025 MMI soil-geochemistry program at the Kate Silver Deposit, part of its 100%‑owned Silver Cliff Project in Colorado. The 549-sample survey across ~1,800 ft2 defined a coherent, high‑grade silver-in-soil anomaly forming a continuous north–south corridor that aligns with structural mapping and historical drilling.

Integration with prior drilling and airborne imagery suggests a near‑surface epithermal system that remains open to the north and northeast. Viscount highlighted historical high‑grade drill results (25 holes with intervals >110 g/t Ag; 10 holes with intervals >400 g/t Ag) and a current NI 43-101 resource estimated at a US$24/oz silver cutoff. No new resource or economic study has been completed. Permitting is underway for a planned 2026 drill program of ~10 holes totaling 500–750 m to test Kate North, Kate Northeast, Ben West, and infill targets.

Pattern Detected

Positive technical exploration news has often led to favorable or mixed price reactions, with one notable selloff despite a strong discovery.

Recent Company History

Over recent months, Viscount has repeatedly highlighted the Silver Cliff Project’s potential. On Aug 14, 2025, a major copper‑gold porphyry discovery at Passiflora still saw shares drop 27.08%, showing a tendency for profit‑taking on strong news. Later updates on expanded work programs and integrated datasets on Sep 9 and Dec 9 produced modest to solid gains of 0.27% and 6.91%. The current Kate silver corridor update extends this technical de‑risking narrative at the same Colorado project.

Market Pulse Summary

The stock surged +12.7% in the session following this news. A strong positive reaction aligns with the company’s pattern of using technical results to expand the Silver Cliff story. The continuous silver-in-soil corridor and historic intervals over 400 g/t support perceived resource upside. However, past news saw a 27.08% drop on good results, so enthusiasm could fade if follow-up drilling underdelivers or funding and timelines become concerns.

Key Terms

epithermal technical

"reinforce Kate as a robust, near-surface epithermal silver system"

Epithermal describes a type of mineral deposit formed when hot fluids near the Earth’s surface deposit metals such as gold and silver into cracks and porous rock, often creating concentrated ‘veins’ or pockets. For investors, epithermal deposits matter because they can host high-grade, easily accessible ore that may lower extraction costs and shorten the time from discovery to production, affecting project value and exploration risk.

MMI soil-geochemistry technical

"The 2025 MMI soil-geochemistry program (549 samples) covering an area"

MMI soil-geochemistry is a soil sampling method that measures the tiny, mobile metal ions that have traveled upward from rocks below, using a gentle chemical wash rather than digging up all the soil. For investors, it matters because this technique can reveal hidden mineral deposits beneath cover—like finding a faint scent that points to food buried under a blanket—helping exploration teams decide where to drill and reducing the risk and cost of early-stage mineral discovery.

NI 43-101 regulatory

"extends beyond the current NI 43-101 resource footprint."

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

breccia pipes technical

"extensions near the Jay Gould breccia pipes, indicating the system remains open."

A breccia pipe is a vertical, pipe-shaped body of broken rock where fragments have been cemented together, often formed by collapsing rock or fluid-driven explosions underground. They can act like concentrated treasure chests for minerals because fluids that carry metals tend to flow and deposit in these open, fractured zones; for investors, that means breccia pipes can host high-grade, compact deposits that may offer attractive exploration targets but also carry geological and permitting risks.

Qualified Person regulatory

"who is a "Qualified Person" (QP) as such term is defined"

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

Vancouver, British Columbia--(Newsfile Corp. - December 11, 2025) - Viscount Mining Corp. (TSXV: VML) (OTCQB: VLMGF) ("Viscount" or the "Company") is pleased to provide an updated interpretation of the 2025 soil-geochemistry program at the Kate Silver Deposit ("Kate"), part of the Company's 100%-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 1800 FT² defined a coherent and highly developed silver-in-soil anomaly centered 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 NI 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 up-coming drill program.

Silver Expansion Potential

The Kate Deposit is a shallow, silver-rich epithermal system that hosts the current NI 43-101 mineral resource based on US$24/oz 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 2025 geochemical survey, combined with historical drilling, highlights expansion potential to the north and northeast. Historical drilling by previous operators returned numerous multi-ounce silver intercepts 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 multi-ounce silver intercepts along a northeast-trending structure. 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.

Viscount Past Drill Highlights

Throughout these six drilling campaigns performed at the Kate, fifty-four drill holes were drilled by Viscount. Of these, twenty-five drill holes presented intervals assaying greater than 110 g/t and ten drill holes displaying intervals assaying over 400 g/t.

About Viscount Mining (TSXV: VML) (OTCQB: VLMGF)

Viscount Mining Corp. is a project generator and mineral exploration company focused on advancing high-quality silver, gold, and copper assets in the Western United States. The Company's portfolio includes the Silver Cliff silver project in Colorado and the Cherry Creek multi-metal district in Nevada.

Silver Cliff Project — Colorado

Silver Cliff is located in the historic Hardscrabble Silver District and comprises 96 lode claims with year-round paved access and established local infrastructure. The project covers a large volcanic caldera system recognized for its silver, gold, and base-metal potential.

The property includes two principal zones of focus:

• Kate Deposit (Silver Resource Area): The Kate hosts a NI 43-101 compliant near-surface silver resource published by an independent QP (details: Measured & 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).
• Passiflora Porphyry Target: Historical and modern drilling indicate extensive hydrothermal alteration consistent with a large porphyry system. Recent drilling by Viscount (hole PF-23-03A) intersected 843.9 metres of continuous copper-gold mineralization, which the Company interprets as being on the periphery of a potentially larger intrusive centre. Mineralization remains open in multiple directions.

Cherry Creek Project — Nevada

Cherry Creek covers 219 unpatented and 17 patented claims in a well-known historic mining district approximately 50 miles north of Ely. The property includes more than 20 past-producing mines and hosts several styles of mineralization, including silver-gold veins, carbonate-replacement (CRD) zones, jasperoids, and porphyry-related alteration. The district is 100% controlled by Viscount and is considered highly prospective for multi-metal discoveries within the broader mineralized system.

Viscount's strategy is to acquire, explore, and advance high-potential mineral properties through systematic geological work, while continuing to build partnerships that support long-term development.
