Blackrock Silver Commences 17,000 Metre Two-Phased Expansion Drill Programs at Tonopah West Project
Blackrock Silver mobilizes for massive 17,000-meter expansion as Tonopah West transitions from discovery to development-ready asset
The most recent news (February 25, 2026) announces the commencement of a two-phased, 17,100-meter expansion drill program at the flagship Tonopah West project in Nevada. The program is split into the Eastern Expansion (9,100m) and the Northwest Expansion (8,000m). This drilling follows high-grade intercepts from late 2025 and aims to grow the mineral inventory beyond the current resource shell. Additionally, the company confirmed that its updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA) are on track for delivery by the end of March 2026. Hydrology programs are also nearing completion, supporting the permitting for an exploration decline and bulk sampling planned for H2 2027.
The news is a Routine - Positive development. While the scale of the drill program (17,000m) is significant and "fully funded," it is a continuation of the strategic roadmap previously communicated to the market. - Confirmation of Timelines: The most critical takeaway is the confirmation that the updated PEA and MRE are due in March 2026. This provides a clear near-term catalyst. - De-risking: The completion of the Phase-2 hydrology program is a vital "boring but necessary" step for permitting the underground decline. - Operational Efficiency: The use of RC/Core hybrid drilling (RC pre-collars with core tails) demonstrates a disciplined approach to capital allocation, maximizing meters while maintaining data quality. - Context: This follows a massive year of share price appreciation (273%) and successful C$15M financing led by Eric Sprott in January 2026. The market has already priced in significant success; this news confirms the company is executing on its promises.
Blackrock Silver Corp. is focused on the Tonopah West project in Nevada, situated along the Walker Lane trend. It is the first time the historic district has been consolidated under one owner. The project is high-grade, with a 2024 PEA showing an after-tax IRR of 39% and AISC of $11.96/oz AgEq. The project is unique because it sits largely on patented mining claims (private land), which significantly streamlines the permitting process compared to federal land.
