07:31 AM EST, 03/03/2026 (MT Newswires) -- Blackrock Silver ( BKRRF ) on Tuesday announced the issuance by the Nevada Department of Environmental Protection (NDEP), through the Bureau of Air Pollution Control, the Class II Air Quality and Surface Disturbance Permit for the company's Tonopah West mineral project located along the Walker Lane Trend in Nye and Esmeralda Counties, Nevada, USA.

The company said that the permit allows for the disturbance of up to 150 acres (60.7 Hectares) at Tonopah West with appropriate dust control measures and an ongoing program using the "best practical methods" to prevent particulate matter from becoming airborne.

It added that the term of the permit is five years, which can be extended and modified as Tonopah West moves toward permitting and construction of its proposed exploration decline, test mining and bulk sample extraction programs.

The company further stated that data collection continues for the hydrogeological and geochemical programs that will form the basis for the Water Pollution Control Permit.

"Five humidity cells are in process to review acid generating potential of the waste and mineralized lithologies that will be encountered and transported to the surface during the tunneling and construction of the exploration decline including stockpiles for mineralized material mined as part of the bulk sample program," said the company.

In a statement, the company noted that the hydrogeological program is designed to understand the groundwater dynamics focused on potential flow and volumes to support required management and disposal as needed during the test mining and bulk sample phase of the program.

"Waste dump, stockpiles and portal entry engineering designs are on schedule and will be completed and used to calculate surface disturbance that will be the cornerstone for the Modification to the Nevada Reclamation Permit," added the company.

It further said that the permitting process is on schedule with all permits anticipated by mid-2027. The company added that once all permits are in hand, it will decide when to commence with the exploration decline, test mining and bulk sample extraction programs at Tonopah West.
