VISCOUNT MINING'S PASSIFLORA DISCOVERY DRILL HOLE INTERSECTS ROBUST COPPER-GOLD PORPHYRY SYSTEM OVER ENTIRE 843.9 METRE INTERVAL

Viscount Mining Corp. has made a pivotal early-stage discovery at its Passiflora porphyry target in Silver Cliff, Colo. The company's first deep drill hole (PF-03A) intersected 843.9 metres of continuous copper-gold mineralization averaging 0.214 per cent copper equivalent, including multiple higher-grade zones such as 189 metres at 0.326 per cent CuEq and 45 m at 0.417 per cent CuEq. These grades exceed typical early-stage porphyry exploration thresholds (approximately 0.15 per cent CuEq) often seen in the initial drilling of deposits that evolved into world-class, long-life operations, and the target remains open in all directions and at depth.

Drill hole PF-03A was designed to test a very strong geophysical anomaly identified by Quantec Geoscience's Titan MT survey in 2023. The survey outlined a strong conductive target beginning at approximately 400 m and extending to at least 1,500 m depth and over two kilometres in horizontal distance. Drilling began in mid-January, 2025, and concluded March 7, 2025, at a final depth of 1,144 m due to equipment challenges, short of the planned 1,500-metre target.

The upper 300 metres of core was not assayed as the Titan MT model indicated the main conductor began around 400 metres. However, visual inspection of the core confirmed strong sulphide mineralization from surface to 300 metres. This zone remains a high-priority target for future sampling and reassessment. The principal objective of the drill hole was to determine whether the geological target was indeed a porphyry system and not a different type of conductive anomaly. The company is thrilled to report that, not only did the drilling confirm the presence of a copper-gold porphyry system, but it also revealed consistently anomalous concentrations of copper, molybdenum, zinc and lead, alongside a significant presence of gold.

Viscount chief executive officer Jim MacKenzie stated: "Grades like this, especially with nearly half the samples above 0.20 per cent CuEq, are a clear signal we're dealing with a significant deposit. The presence of multiple, thick, higher-grade zones -- such as 189 m at 0.326 per cent CuEq including 45 m at 0.417 per cent CuEq, and 99 m at 0.278 per cent CuEq including 24 m at 0.306 per cent CuEq -- well above typical early-stage porphyry levels, reinforces Passiflora's potential as an extensive, long-life copper-gold system."

"From a geological standpoint, PF-03A is an exciting first step," said Mark Abrams, vice-president of exploration for Viscount Mining. "The consistent copper values throughout the hole, the upward grade trend with depth and the presence of multiple minerals typically associated with mature porphyry systems all point to a robust porphyry deposit. These are exactly the kind of early results we look for in a discovery program. TWhe system is open in every direction, and we've only just begun to explore its full potential."

A porphyry copper deposit is a specific subtype genetically and structurally associated with porphyritic intrusive igneous rocks. These systems are among the world's largest sources of copper, often measuring three to eight km across and containing hundreds of millions to billions of tonnes of ore, albeit at generally low copper grades (approximately 0.2 to 1 per cent). The PF-03A drill hole results confirm that the Passiflora target is a porphyry-style system -- an encouraging outcome because such deposits have the potential to support long-life, large-scale mining operations.

Summary statistics:

• Average CuEq: 0.2163 per cent (2,163 parts per million);
• Maximum CuEq: 0.7826 per cent (7,826 ppm) -- sample 179326;
• Minimum CuEq: 0.0361 per cent (361 ppm) -- sample 179211;
• Standard deviation: approximately 0.146 per cent.

Economics

• Average grade 0.2163 per cent -- well above typical porphyry cut-off.

Key observations:

• Gold dominates the copper equivalent value (40.1 per cent);
• Copper remains significant at 48.9 per cent of total value;
• Economic continuity excellent with 47 per cent of samples above cut-off;
• Resource potential upgraded due to gold credit.

Deposit classification

This is a gold-rich porphyry copper deposit with:

• Primary copper mineralization (48.9 per cent of value);
• Significant gold credits (40.1 per cent of value);
• Supporting polymetallic credits (zinc, molybdenum and lead).

• Lead, zinc and molybdenum are also present;
• Lead up to 1.02 per cent;
• Zinc up to 0.33 per cent;
• Molybdenum values reaching 892 ppm.

All 303 samples reported above have a detection limit for gold, with scattered half-gram-per-tonne results, with a high gold anomaly of 918 parts per billion Au. The hole is averaging 134.16 ppb Au.

Copper grades consistently increased with depth, suggesting that stronger mineralization may continue beyond the current hole bottom. Anomalous zinc and lead were encountered throughout, with lead peaking at 1.02 per cent. Gold was detected in every fire-assayed sample over the 843.9 metres, with values up to 918 ppb.

With grades already above typical early porphyry exploration thresholds and nearly half its samples in the economic range, these results from hole PF-03A are an exceptional start.

The Passiflora deep discovery hole is located approximately 3.2 km north of the town of Silver Cliff, within the Ben West volcanic centre as mapped by the USGS (Sharp, 1978). The project remains open in all directions and at depth.

The main body of the conductive anomaly starts at a depth of approximately 400 m and continues another approximately 1.5 km, maybe deeper (this was the extent of the MT survey depth capability). The length of the anomaly is approximately 2.4 km in the southwest-northeast direction with a width of at least 700 m and an open interpretation in multiple directions. This represents a total volume of over 665 million cubic metres as determined by Quantec.

Passiflora's early CuEq intercepts (approximately 0.18 to 0.21 per cent CuEq) sit within the range of early-stage results from some recognized world-class porphyry discoveries. The results are encouraging, particularly because copper is increasing with depth and multiple metals are present.

Next steps

Viscount's technical team is planning an expanded drilling campaign to test deeper into the Titan MT anomaly at the Passiflora and step out laterally to define the system's scale. Further metallurgical work will be undertaken to assess potential recovery rates for all metals.

Sample handling and analytical procedures

Drilling on the deep Passiflora target began on Jan. 22, 2025, by Godbe Drilling from Montrose, Colo. Core was placed in boxes and moved to Viscount's field camp in Silver Cliff for rock quality determinations and preliminary logging. The core boxes were palletized in the field camp and shipped with Old Dominion Freight to MLD, an independent contractor, based in Carlin, Nev. The core was cut in half so 50 per cent could be retained for later examination and analysis. The remaining 50 per cent is the assay split used for the sample. It was photographed by MLD employees, and standards, blanks and duplicates were inserted at regular intervals as determined by Viscount's Silver Cliff drill program procedures by C. Ricks, an independent geologic consultant.

The core samples were bagged and palletized by C. Ricks and shipped by Old Dominion Freight to SGS prep facility in Phoenix, Ariz. SGS added its quality assurance/quality control procedures. The samples then got shipped from the SGS Phoenix facility to the SGS analytical facility in Burnaby, B.C., Canada, for ICP analysis with a method code description of four-acid digestion (HCl/HClO4/HF/HNO3) ICP. Fire assay analysis for gold through FAA30V5 with a method code of Au, FAS, exploration grade and AAS.

About Viscount Mining Corp.

Viscount Mining is a project generator and an exploration company with a portfolio of silver and gold properties in the western United States, including Silver Cliff in Colorado and Cherry Creek in Nevada.

The Silver Cliff property in Colorado lies within the historic Hardscrabble silver district in the Wet Mountain Valley, Custer county, south-central Colorado. It is located 44 miles west-southwest of Pueblo, Colo., and has year-around access by paved road. The property consists of 96 lode claims where high-grade silver, gold and base metal production came from numerous mines during the period 1878 to the early 1900s. The property underwent substantial exploration between 1967 and 1984. The property is interpreted to encompass a portion of a large caldera and a highly altered sequence of tertiary rhyolitic flows and fragmental units, which offer potential to host deposits with both precious and base metals. This has been demonstrated in the mineralization historically extracted from the numerous underground and surface mining operations. Based on the accumulated data and feasibility study, Tenneco Minerals made the decision with silver at $5 (U.S.) an ounce to construct at that time a $35-million (U.S.) milling operation for the extraction of the silver reserves at Silver Cliff. Shortly thereafter, Tenneco's mining unit was sold, and the planned milling operation was abandoned.

The Cherry Creek exploration property is in an area commonly known as the Cherry Creek mining district, located approximately 50 miles north of the town of Ely, White Pine county, Nevada. Cherry Creek consists of 578 unpatented and 17 patented claims as well as mill rights. Cherry Creek includes more than 20 past-producing mines.
