Programs Designed To Advance The Silver Cliff Project
VANCOUVER – Viscount Mining Corp. has executed a contract for a high-resolution airborne electromagnetic (EM) and magnetic survey at its flagship Silver Cliff Project in Colorado. This program represents a key step in Viscount’s systematic approach to advancing its understanding of the district-scale mineral system and further advancing its understanding of an interpreted gold-copper porphyry system identified at depth.
The newly commissioned airborne survey is expected to: 1) Sharpen drill targeting across the broader system. 2) Identify additional high-priority zones for expansion. 3) Define the scale and continuity of mineralization at depth.
Importantly, earlier geophysical work has already outlined a deep anomaly extending to approximately 1.5 kilometres, suggesting the system could be significantly larger than initially interpreted. By deploying advanced geophysics at this stage, Viscount is positioning itself to accelerate discovery and maximize the impact of future drilling campaigns, a key value driver for shareholders.
With both a substantial silver resource at Kate and a rapidly emerging gold-copper opportunity at Passiflora, the Silver Cliff project is evolving into a compelling multi-commodity exploration story in a proven mining jurisdiction.
Under the agreement, Rosor will deploy its advanced drone-based EM and magnetic surveying platform across approximately 3.5 km² of the Silver Cliff property. The survey is designed to generate high-resolution subsurface data, including 2D and 3D resistivity models and detailed magnetic datasets, which will assist in delineating geological structures, alteration zones, and potential mineralized targets.
Importantly, this program is designed to complement and enhance the Company’s prior deep-penetrating TITAN MT geophysical survey conducted by Quantec Geoscience. While the Quantec study identified a large-scale, coherent anomaly at depth consistent with a potential porphyry system, the Rosor survey will provide higher-resolution data to bridge near-surface and intermediate depths. Together, these datasets are expected to significantly improve targeting by linking deep conductive features to shallower structural and alteration patterns.The Rosor survey builds directly on Viscount’s recent discovery drilling at the Passiflora target, where the Company completed its first deep drill hole (PF-03A), intersecting: 1) 843.9 metres of continuous gold-copper mineralization averaging approximately 0.214% CuEq. 2) Including 189 metres at 0.326% CuEq, with a higher-grade interval of 45 metres at 0.417% CuEq, and 99 metres at 0.278% CuEq, including 24 metres at 0.306% CuEq.
These results are notable in that they exceed typical early-stage porphyry exploration thresholds (~0.15% CuEq) and demonstrate strong grade continuity over significant widths.
Mark Abrams, Vice-President of Exploration, said, “The integration of this high-resolution airborne survey with our existing Quantec dataset provides a powerful framework to vector toward what we believe may represent a large-scale gold-copper porphyry system. We are systematically de-risking and unlocking the full potential of the project.”
