VISCOUNT STRENGTHENS GOLD-COPPER PORPHYRY MODEL AT PASSIFLORA AS MULTIPLE EXPLORATION DATASETS ALIGN

Viscount Mining Corp. has released the results of its 2025 multiphase exploration program at the Passiflora copper-gold porphyry on the Silver Cliff project in Custer county, Colorado. New MMI soil geochemistry, when integrated with airborne imagery, Quantec MT geophysics, rock sampling, geological mapping and historical drilling, continues to strengthen the interpretation of a large, district-scale porphyry system centred below the Passiflora corridor.

The convergence of these independent data sets is providing the strongest technical case to date for a significant gold-copper intrusive centre, with vectors now clearly defined for both shallow and deep drill testing in 2026.

A broad, coherent copper-gold corridor emerging

The 2025 MMI soil survey outlines a well-defined copper-in-soil trend across the central western portion of the grid, remaining open to the west and north, and closely aligned with conductivity highs identified in the Quantec MT survey. These high-conductivity MT features are interpreted as indicators of a deep intrusive centre, a common signature in large-scale porphyry environments.

Overlapping clusters of elevated gold-in-soil values coincide with the copper trend and are characteristic of leakage halos above mineralized porphyry centres. This dual-response copper and gold provides increased understanding in the geometry of the subsurface system.

Supporting data sets include:

• Rock sampling along Ben Hill West, which returned elevated copper and porphyry pathfinder metals directly above the central MT feature;
• Airborne imagery outlining a broad alteration halo following the same structural corridor;
• Historical drilling records documenting porphyry-style alteration mineral assemblages;
• Viscount's deep hole PF-23-03A, which intersected long intervals of copper-gold mineralization interpreted to lie on the periphery of a larger intrusive system;
• Five shallow holes drilled in 2021, of which four encountered widespread anomalous base metals, silver, gold and alteration assemblages consistent with the outer halo of a porphyry system.

These integrated lines of evidence support a multiphase intrusive-hydrothermal system of meaningful scale, now better delineated by soil chemistry, MT responses, surface mapping and drilling.

Advancing toward 2026 drilling

Following compilation and integration of all data sets, Viscount has defined a drill plan targeting both the near-surface USGS-mapped breccia pipes and the deeper porphyry centre indicated by the MT anomaly.

According to the Quantec report 2022, The 2-D and 3-D modelled depth of the anomaly extends approximately 1,500 metres deep, or to an elevation of approximately 900 m, but the source could be deeper. The extreme conductivity of the anomaly and sensitivity of the MT method limit resolution of the inversion result below the massive conductive zone. The information that the company has of the deep parts of the model comes from the sites that are not directly above the anomaly, so the deeper part of the anomaly may not be well defined with the data and coverage available.

The company will test several breccia bodies mapped by the USGS, interpreted as structurally prepared conduits that can host enriched mineralization proximal to porphyry systems. These targets provide cost-effective, shallow drill opportunities as part of the 2026 program.

The next deep drill hole is designed to test the strongest portion of the MT anomaly, representing a significant stepout from hole PF-23-03A. A similar mineralization profile grade, alteration and continuity would confirm lateral extension and strengthen the interpretation of a large porphyry system at depth. A positive outcome from either drill program would advance the Passiflora target and elevate its standing as a district-scale gold-copper opportunity for Viscount.

Historical mine records reinforce regional metal endowment

Viscount recently obtained historical mine reports (1908 to 1968) from the Colorado State Archivist's Office covering underground operations in the broader Hardscrabble mining district surrounding the company's first deep drill hole (PF-03A) which intersected 843.9 metres of continuous copper-gold mineralization. Although incomplete, the records document multiple underground shipments grading approximately 10 to 15 per cent lead and five to 15 ounces/ton silver, with additional gold and zinc credits noted in several of the annual reports. These reports highlight the long-recognized polymetallic enrichment of the district and provide context for the broader mineralizing system that Passiflora is part of.

Integrated interpretation

Taken together, the copper and gold data sets show two overlapping geological systems:

• Copper-gold-pathfinder geochemical corridor consistent with a deeper porphyry source, spatially aligned with Quantec MT conductivity highs, mapped alteration and the mineralized intervals intersected in Viscount's deep hole PF-23-03A.

Next steps

Viscount is now finalizing drill collar locations for holes targeting both the USGS-mapped breccia pipes and the deeper core hole designed to test the strongest portion of the MT anomaly at Passiflora. The technical team is continuing to integrate soil geochemistry, structural mapping and MT geophysical data into a refined 3-D targeting model to optimize drill placement and maximize geological insight from the initial holes. The first drill hole of 2026 is designed to test the breccia pipes and continue through to the heart of the Quantec MT anomaly. This angled hole is anticipated to be about 1,500 metres. Permitting activities are under way and progressing in line with expectations, keeping the company on schedule to begin drilling in early 2026, subject to the receipt of final approvals.

About Viscount Mining Corp.

Viscount Mining 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 multimetal 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 National Instrument 43-101-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).
• 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 per cent controlled by Viscount and is considered highly prospective for multimetal 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.

We seek Safe Harbor.
