Viscount talks 2025 exploration program at Silver Cliff

Executive Summary

• Viscount Mining Corp. has released results from its 2025 multiphase exploration program at the Passiflora copper-gold porphyry target on the Silver Cliff project in Colorado, strengthening the geological model of a district-scale porphyry system.
• The company has defined a drill plan for 2026 targeting both near-surface USGS-mapped breccia pipes and the deeper porphyry center indicated by Quantec MT geophysics, with drilling anticipated to begin in early 2026.
• Historical mine records obtained from the Colorado State Archivist reinforce the regional polymetallic potential, documenting past shipments of lead, silver, gold, and zinc in the surrounding Hardscrabble mining district.

Key Details

• Geological Model: Integration of 2025 MMI soil geochemistry, airborne imagery, Quantec MT geophysics, rock sampling, geological mapping, and historical drilling supports a large, district-scale copper-gold intrusive center.
• Geochemical Trends: A well-defined copper-in-soil trend exists in the central western grid, open to the west and north, aligned with high-conductivity MT features interpreted as a deep intrusive center. Elevated gold-in-soil values overlap with the copper trend, characteristic of leakage halos above mineralized porphyry centers.
• Supporting Data:
  • Rock sampling along Ben Hill West returned elevated copper and porphyry pathfinder metals above the central MT feature.
  • Airborne imagery outlines a broad alteration halo following the structural corridor.
  • Historical drilling documents porphyry-style alteration mineral assemblages.
  • Deep hole PF-23-03A intersected long intervals of copper-gold mineralization interpreted to lie on the periphery of a larger intrusive system.
  • Five shallow holes drilled in 2021: four encountered widespread anomalous base metals, silver, gold, and alteration assemblages consistent with the outer halo of a porphyry system.
• Geophysics (Quantec MT): The 2-D and 3-D modelled depth of the anomaly extends approximately 1,500 metres deep (elevation ~900 m), though the source could be deeper. The extreme conductivity limits resolution below the massive conductive zone.
• 2026 Drill Plan:
  • Targets include USGS-mapped breccia pipes (interpreted as structurally prepared conduits) and the deeper porphyry center.
  • The next deep drill hole will test the strongest portion of the MT anomaly, representing a significant stepout from hole PF-23-03A.
  • The first 2026 drill hole is designed to test breccia pipes and continue through to the heart of the Quantec MT anomaly.
  • The angled hole is anticipated to be approximately 1,500 metres.
  • Permitting is underway, with drilling expected to begin in early 2026, subject to final approvals.
• Historical Context: Historical mine reports (1908–1968) from the Hardscrabble mining district document underground shipments grading approximately 10–15% lead and 5–15 oz/ton silver, with additional gold and zinc credits.
• Historical Drilling Reference: Hole PF-23-03A previously intersected 843.9 metres of continuous copper-gold mineralization.

Notable Quotes

• "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 positive outcome from either drill program would advance the Passiflora target and elevate its standing as a district-scale gold-copper opportunity for Viscount."
