Blackrock Silver Corp. (TSXV:BRC) - NW Step Out Drilling Extends Mineralization by 600m - Research Portal

Blackrock announced the first tranche of step-out drill results from its Tonopah West Ag project in Nevada. Results are from 12 holes, with six targeting the NW Step Out area and the remaining drilled at the Eastern Expansion area. Drilling at NW Step Out extended mineralization by ~600m along the Denver Vein system. Standout intercepts graded 1,096 g/t AgEq over 0.49m from NW Step Out and 1,036.6 g/t AgEq over 0.76m at Eastern Expansion. The key takeaway from these results is scale. Extending the Denver corridor 600m northwest beyond the March 2026 resource adds meaningful strike to this ~123M oz AgEq system. That said, the results are relatively narrow. Most intercepts are under 1m drilled, well below a practical underground mining width. One encouraging sign is TXC26-200, which cut nine separate mineralized intervals over ~170 m, pointing to a stacked vein swarm rather than a single structure. Further, the new intrusive target emerging to the NW is geologically interesting and warrants follow-up. Additional drilling is underway, and in the near term, we look forward to pending assays from 12 additional holes.
