Colorado Silver Drilling Hits 1,030 g/t Beyond the Existing Resource

Source: Streetwise Reports (9/24/26)

Viscount Mining Corp. (VML:TSX.V; VLMGF:OTCQX) reported final Silver Cliff assays from ten drill sites outside the current Kate resource boundary, including 7.9 meters grading 473.2 g/t silver and 2.92 g/t gold.

Key Takeaways:

  • Viscount Mining reported silver mineralization beyond the existing Kate Silver Resource boundary, with all ten holes in its approximately 830-meter Silver Cliff drill program located outside the currently defined resource.
  • The strongest Silver Cliff result came from hole K26-08, which returned 7.9 meters grading 473.2 g/t silver and 2.92 g/t gold, including 1.5 meters grading 1,030 g/t silver and 1.65 g/t gold.
  • Five of six Kate resource-expansion holes returned qualifying mineralized intervals using a 15 g/t silver cutoff, while the company said the newly encountered mineralization was not currently included in the existing resource’s modeled tonnes or ounces.
  • Viscount planned additional work at Silver Cliff, including soil-geochemical work, further analysis, and a follow-up drilling program later in 2026, while evaluating the timing of an updated Kate mineral resource estimate.

Viscount Mining Corp. (VML:TSX.V; VLMGF:OTCQX) reported final assay results from its ten-hole, approximately 830-meter 2026 drilling program at the Silver Cliff Project in Custer County, Colorado, with all ten drill sites located outside the currently defined Kate NI 43-101 resource boundary.

The drill sites ranged from 67.7 meters to approximately 1 kilometer from the Kate Silver Resource outline. Six holes tested Kate’s resource-expansion ground between 67.7 and 117.7 meters from the existing resource, while four northern holes tested the broader structural trend between 573.6 meters and approximately 1 kilometer from the resource.

The strongest assay results of the program came from K26-08, which returned 13.4 meters, averaging 267.6 grams per tonne silver. That interval included 7.9 meters grading 473.2 g/t silver and 2.92 g/t gold, including 1.5 meters grading 1,030 g/t silver and 1.65 g/t gold. A separate 1.8-meter interval within the same higher-grade core graded 675 g/t silver and 10.20 g/t gold. The entire 184.1-meter assayed hole averaged 21.8 g/t silver.

Using a 15 g/t silver cutoff for the 2026 results, three holes averaged more than 20 g/t silver across their entire assayed lengths. K26-04 averaged 28.9 g/t silver over 56.4 meters, K26-08 averaged 21.8 g/t silver over 184.1 meters, and K26-09 averaged 21.7 g/t silver over 62.3 meters.

Five of the six Kate resource-expansion holes returned qualifying composite intervals at or above the 15 g/t silver cutoff. K26-04 returned 45.7 meters, averaging 34.1 g/t silver, including 24.4 meters, averaging 48.9 g/t silver. K26-09 returned 18.0 meters averaging 46.0 g/t silver, including 6.1 meters averaging 93.2 g/t silver and 1.5 meters grading 182 g/t silver. K26-10 returned 12.5 meters, averaging 15.3 g/t silver, including 4.0 meters, averaging 54.1 g/t silver.

Project Manager and Geologist Chrissy Ricks said, “Applying the 15 g/t silver cutoff highlights the breadth and more continuous zones of silver mineralization across the 2026 drilling. The drill program has significantly advanced the Silver Cliff story, strengthening both our open-pit resource-expansion opportunity at Kate and the broader exploration potential to the north.”

The four northern holes tested soil-geochemical anomalies along the structural trend the company is evaluating between Kate and Passiflora. K26-07 returned 15.9 meters, averaging 28.1 g/t silver, including 1.2 meters grading 212 g/t silver and 0.38 g/t gold. K26-08, drilled toward the company’s PF-03A porphyry discovery hole at Passiflora, produced the strongest silver-gold assays of the program.

The program also returned manganese, zinc, and lead anomalies across the drill-core samples assayed. Manganese exceeded 1,000 ppm in 196 of 506 samples, including 76 samples above the laboratory’s 1,000 ppm upper reporting limit for the routine analytical method. Zinc exceeded 1,000 ppm in 146 of 506 samples, while lead exceeded 1,000 ppm in 116 of 506 samples.

The current April 2023 Kate mineral resource remains unchanged by the 2026 drilling and contains 10.275 million ounces of silver in the measured and indicated categories at an average grade of approximately 71 g/t silver, plus 14.215 million inferred ounces at approximately 52 g/t silver. The company said the mineralization encountered beyond the existing resource boundary is not currently included in the modeled tonnes or ounces.
