Viscount Mining completes first phase of Silver Cliff drill program, Colorado – Resource World Magazine

Viscount Mining Corp. [TSXV: VML; OTCQX: VLMGF] reported completion of the first phase of the core drill campaign at the Silver Cliff Project in Colorado, where the final four drill holes (K26-05 through K26-08) encountered widespread hydrothermal alteration, brecciation, manganese-oxide mineralization, strong sulphide mineralization with increasing intensity, visible galena and localized massive sulphide veining north of the Kate Resource area. The company believes these results support its interpretation that the mineralized hydrothermal system at Silver Cliff extends beyond the current Kate Silver resource area and northward toward the Passiflora porphyry target and the Ben West volcanic complex, potentially indicating proximity to a larger mineralized system. Notably, hole K26-08 intersected a localized massive-sulphide vein together with visible galena and possible chalcopyrite, associated with strong pyrite mineralization and alteration. All mineralization described in this release is based on visual examination of drill core only. Assays for the 2026 program are pending. Visual estimates are inherently imprecise, are not a substitute for laboratory assays, and should not be relied upon as an indication of grade or economic mineralization. 2026 Program Highlights: Completed four final holes (K26-05 to K26-08) testing both resource-expansion targets around the Kate deposit and new district-scale structural targets to the north; intersected multiple zones of phyllic alteration, silicification and hydrothermal brecciation along major structural corridors; observed visually increasing sulphide intensity with depth, including a localized massive-sulphide vein in hole K26-08 and identified visible galena and possible chalcopyrite in K26-08, consistent with the Company’s base-metal and porphyry-related exploration model. Assays for all holes are pending and will be released once received, compiled and interpreted. Jim MacKenzie, CEO and Director stated, “These final holes significantly strengthened our belief that Silver Cliff hosts a large-scale mineralized hydrothermal system extending well beyond the current Kate resource area. The increasing sulphide intensity, strong alteration and localized massive sulphide mineralization encountered in K26-08 are particularly encouraging and may indicate we are vectoring toward a more robust mineralized center associated with the Passiflora target. With assays pending and geophysics now underway, we believe Silver Cliff continues to demonstrate meaningful district-scale discovery potential.” The final four core holes of the Kate drill program were designed to test two anomalies identified during the soil survey north of the Kate Silver resource area. This area has historically received very limited attention, despite its proximity to the historic Defender mine, a past producer of lead and silver. The first two holes (K26-05 and K26-06) tested the more southerly soil anomaly, while the final two holes (K26-07 and K26-08) tested a strong anomaly located in the north-west corner of the soil survey. Hole K26-05 was designed to test a major north-south structural corridor north of the Kate resource, near Colorado Quarry Road. The hole intersected broken to brecciated rhyolite with manganese-oxide, limonite and hematite staining associated with multiple fracture sets, before transitioning into a strongly altered phyllic zone characterized by silicification, angular hydrothermal-breccia textures and finely disseminated sulphides. The company notes that phyllic alteration of this type is commonly associated with porphyry-related hydrothermal systems and is comparable to alteration’s observed near the historic Passiflora and Defender mines in the Silver Cliff district. The hole terminated at 276 feet (84 metres) while remaining within the alteration zone. It was drilled to the north along a north-trending fault zone that hosts three shafts along trend. The hole encountered very muddy overburden from surface to approximately 14 feet, below which competent rock was intersected. The core contained a few breccia zones together with disseminated sulphides visually estimated at approximately 8% to 15% over its 276-foot (84-metre) length (visual estimate only – not an assay). Hole K26-06 was drilled as a follow-up along the same north-south structural corridor. Due to significant near-surface clay alteration, the company adjusted the drill orientation to better penetrate the target zone. The hole intersected persistent phyllic alteration, brecciation and finely disseminated pyrite over substantial intervals, consistent with a broad hydrothermal alteration system extending northward from the Kate resource. It was drilled to the north-west from the same drill location and showed phyllic alteration. The intensity of the alteration diminished as the hole progressed, which the Company interprets as the hole becoming more distal to the heat source. Hole K26-07 tested the southern rim of the Ben West volcanic complex within the Miocene-aged Tbb rim-breccia unit. The hole provided important geological information on the volcanic and structural architecture linking the Kate and Passiflora areas. The Company believes the Ben West complex may represent a hydrothermal centre capable of focusing mineralizing fluids across the district. K26-07 and K26-08 were drilled to test the strongest soil anomaly, located in the north-west corner of the soil survey. K26-07 was drilled vertically. The hole intersected the volcanic rim breccia and exhibited strong phyllic alteration, with some sulphide zones logged as almost solid. Hole K26-08 was among the most geologically encouraging holes of the 2026 program. Drilling encountered a distinct oxidized-to-unoxidized transition at approximately 68 feet (20.7 metres), below which the visual intensity of sulphide mineralization increased substantially. Logged features include increasing sulphide intensity with depth; visible galena and possible chalcopyrite; sulphide-rich breccia zones; a localized massive sulphide vein at depth; strong phyllic alteration associated with major structural corridors and a localized solid pyrite vein approximately one foot (0.3 metres) in length at approximately 486 feet (148.1 metres). With increasing depth, sulphides were observed visually as disseminations, fracture-fill, stringers, blebs and localized massive-sulphide veins. The company believes these features may reflect increasing proximity to a more strongly mineralized portion of the system. As noted above, these are visual observations only and remain subject to confirmation by assay. K26-08 was originally planned to be drilled to the north-west; however, following the results of K26-07, the hole was instead drilled toward the north-east. Like K26-07, it intersected the volcanic rim breccia and exhibited strong phyllic alteration, with some sulphide zones logged as almost solid. The hole also intersected metallic-looking crystals that were not identified in the field; these are expected to be identifiable once geochemical results are received. Given the strong gold and silver values returned from soil sampling in this area, the Company believes the pyrite may be the host for gold and silver. This is a preliminary interpretation based on visual core logging and soil geochemistry only; it has not been confirmed by assay of the drill core, which is pending. The 2026 drill program indicates that hydrothermal alteration and visible mineralization extend beyond the current Kate Silver resource boundary and continue northward toward the Passiflora area and the Ben West volcanic complex. Across multiple holes, targeting expansion potential north of the Kate Resource the program intersected broad zones of phyllic alteration, silicification and hydrothermal brecciation; observed increasing sulphide intensity with depth across multiple holes. Hole K26-08 encountered visible galena, possible chalcopyrite and localized pyrite veins. Geological indicators suggest vectoring toward a larger mineralized system associated with the Passiflora target. Assays pending for all holes. The company believes these characteristics are consistent with a vertically and laterally extensive hydrothermal system with the potential to host both near-surface silver mineralization and deeper porphyry-related mineralization. This interpretation is preliminary and based on visual core logging; it has not been confirmed by assay results or by a mineral resource estimate. Assays from the 2026 holes are pending and will be released once received, compiled and interpreted. True widths of the intervals described have not been determined, and reported lengths are downhole (core) lengths. The company has now completed its 2026 drill campaign and is advancing toward the next phase of exploration at Silver Cliff. Assays from all 2026 drill holes are currently pending and will be released once received, compiled and interpreted. In parallel, Rosor Exploration has mobilized to begin a district-scale geophysical survey designed to further define structural corridors and prioritize follow-up drill targets along the emerging Kate-Passiflora trend. The Company believes the integration of drilling, soil geochemistry and geophysical data will significantly enhance targeting as it continues to evaluate the broader district-scale hydrothermal system and the potential for deeper porphyry-related mineralization. The company also reported that its Board of Directors has approved the granting of 7,375,000 stock options to directors, management and consultants pursuant to the Company’s stock option plan. The options are exercisable at a price of $0.50 per share for a period of five years and remain subject to applicable regulatory approvals. 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, and contains two principal areas of focus: Kate Deposit (Silver Resource Area): the Kate deposit hosts a near-surface silver mineral resource estimated in accordance with NI 43-101 standards and prepared by an independent qualified person. Passiflora Porphyry Target: historical and modern drilling indicate extensive hydrothermal alteration consistent with a large porphyry system. Drilling by Viscount in hole PF-23-03A intersected a 843.9-metre downhole interval of gold-copper mineralization, which the company interprets as lying on the periphery of a potentially larger intrusive centre. The reported length is a downhole (core) length; true width has not been determined, and readers are referred to the Company’s news release dated [insert original release date] and its filings on SEDAR+ for the associated assay results and details. Mineralization remains open in multiple directions. Cherry Creek comprises 219 unpatented and nine patented claims in a historic mining district approximately 50 miles north of Ely, Nevada. 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 prospective for multi-metal discoveries within the broader mineralized system.
