Viscount talks next stages exploration at Silver Cliff
Executive Summary
- Viscount Mining announced expanded exploration programs at its flagship Silver Cliff project, targeting growth of the Kate silver resource and further delineation of the newly discovered Passiflora copper‑gold porphyry deposit.
- The Kate deposit currently holds a NI 43‑101 compliant resource of 10.3 M oz measured & indicated and 14.2 M oz inferred silver; the new program aims to validate up to 25 M oz of historic estimates and incorporate them into the compliant framework.
- Initial deep drilling at Passiflora (hole PF‑03A) intersected 843.9 m of continuous mineralization averaging 0.214 % CuEq, with higher‑grade zones of 0.326 % and 0.417 % CuEq, establishing a robust porphyry system that remains open in all directions.
Key Details
- Kate Silver Resource (KSR)
- Current NI 43‑101 resource: 10.3 M oz measured & indicated at 72 g/t Ag; 14.2 M oz inferred at 52 g/t Ag.
- Expansion goal: validate up to 25 M oz of historic silver estimates and add them to the compliant resource base.
-
Program components: surface mapping, geochemical sampling, ground‑magnetics and IP surveys to refine drill targets.
-
Passiflora Copper‑Gold Porphyry
- Hole PF‑03A results: 843.9 m continuous mineralization, avg. 0.214 % CuEq; includes 189 m @ 0.326 % CuEq and 45 m @ 0.417 % CuEq.
- Mineralization remains open at depth and laterally; copper grades increase toward the bottom of the hole.
-
Next‑phase work: reverse‑circulation drilling of two mapped breccia pipes, integration of a 598‑sample SGS MMI soil survey, induced‑polarization and resistivity geophysics to broaden targeting.
-
Market Context
- U.S. Department of the Interior added silver to its critical minerals list (Feb 2025).
-
Silver price has risen above US$40/oz (highest since 2011), implying an approximate 60 % uplift in the in‑situ value of the existing Kate resource.
-
Historical Silver Potential at Passiflora
-
CoCa Resources (1983) reported a historic reserve of ~60 M oz Ag at 51.9 g/t; Viscount will re‑evaluate this using modern QA/QC protocols for future NI 43‑101 compliance.
-
Qualified Person Review
- Technical information reviewed and approved by Harald Hoegberg, PG, independent consulting geologist (NI 43‑101 qualified person).
