Multiple Intercepts & Establish Grade Continuity At Tonopah West

VANCOUVER – Blackrock Silver Corp. reported the final set of high-grade silver and gold drill intercepts from its recently completed M&I Conversion Program at the Tonopah West project located in Nye and Esmeralda Counties, Nevada.

The Company has completed its in-fill drilling program at Tonopah West which commenced in mid July 2024 and consisted of 62 drillholes totalling 12,580 metres (41,271 feet) within the shallow southern portion of the Bermuda-Merten vein group (DPB) resource area. The objective of the M&I Conversion Program is to convert between 1.0 and 1.5-million tonnes of material from inferred mineral resources to measured and indicated mineral resources. The M&I Conversion Area represents the initial years of anticipated production at Tonopah West based on the mine plan laid out in the Company’s Preliminary Economic Assessment on Tonopah West.

Andrew Pollard, President and Chief Executive Officer, said, “With all assays now received from our M&I Conversion Program, we’ve validated our geologic model at Tonopah West and confirmed continuous high-grade mineralization over a 350-metre zone. Results from this program featured standout grades that reinforce the Tonopah West project’s position as one of the top undeveloped silver assets in the sector. In addition to strengthening confidence in known zones through tighter drill spacing, the program also outlined new near-surface zones of ultra-high-grade gold and silver mineralization, representing meaningful new tonnage potential. These results will be incorporated into an updated mineral resource estimate on Tonopah West anticipated to be completed Q3 2025, aimed at upgrading significant tonnage to the measured and indicated categories to help de-risk the early years of anticipated production.”
