Blackrock Silver Reports $437M Value for Tonopah West Silver-Gold Project

Blackrock Silver CEO Andrew Pollard released an updated Preliminary Economic Assessment on March 31 valuing the Tonopah West project at $437 million on a post-tax, net present value basis, a figure anchored to a deposit sitting roughly one kilometer west-northwest of downtown Tonopah on the Nye-Esmeralda county line.

The base case assumes $31 per ounce for silver and $2,700 per ounce for gold, producing an after-tax internal rate of return of 28% across an 11.2-year mine life. Average annual output is projected at about 7.1 million silver-equivalent ounces, requiring $190 million in initial capital, including contingency.

Those numbers rest on a substantially larger resource base than prior estimates. The updated Mineral Resource Estimate, prepared by RESPEC and effective January 4, 2026, reflected a 90% increase in indicated mineral resources, which prompted the revised economic study.

For Tonopah, the PEA is the clearest statement yet of what the project would actually require. Construction at that scale generates jobs in two distinct phases: a capital-intensive build-out and a smaller, longer-duration operations crew. Blackrock has not yet published a workforce estimate for either phase, and that number is among the first concrete figures Nye County officials and residents should request at any stakeholder meeting the company convenes.

Water rights represent another threshold with a public paper trail. The project sits on private land, which removes some federal permitting steps, but Nevada water law requires separate adjudication of any new mining water rights. When Blackrock files a water rights application with the Nevada Division of Water Resources, those documents become public record and will specify the volume and source the operation would draw on.

Trucking routes matter in a town Tonopah's size. Construction and ore-hauling traffic to a site just west of town would travel existing county and state roads, with specific corridors subject to Nye County review. If Blackrock advances to prefeasibility, county officials can expect to negotiate road-use agreements tied to heavy-haul traffic that those roads were not built to absorb indefinitely.

On the revenue side, Nevada's net proceeds of minerals tax means an operating mine projecting 7.1 million silver-equivalent ounces annually at base-case prices would generate tax receipts for the county, though the final figure depends on operating costs and deductions that will only be refined through a full prefeasibility study.

The PEA is a financial document, not a construction commitment. The next formal milestones are permit applications with state and county agencies, environmental baseline studies, and that prefeasibility study, each requiring public filings and, typically, public scoping meetings. Blackrock trades on the TSX Venture Exchange as BRC and on OTC markets as BKRRF; Nye County residents can monitor permit filings through the Nevada Division of Environmental Protection and the county planning office as the company's timeline takes shape.
