Blackrock Silver (TSX-V:BRC) has received an air quality and surface disturbance permit for its Tonopah West Project in Nevada, marking the first of three key permits required for planned exploration activities.
The Nevada Department of Environmental Protection permit allows for disturbance of up to 60.7 hectares at the project, which lies along the Walker Lane trend in Nye and Esmeralda counties.
The five-year permit includes provisions for dust control measures and requires ongoing implementation of best practices to prevent airborne particulate matter.
The company continues collecting data for hydrogeological and geochemical programs to support its water pollution control permit application. Five humidity cells are being tested to assess acid-generating potential of waste and mineralised materials that will be extracted during planned tunnelling operations.
Hydrogeological studies are focusing on groundwater dynamics to determine management requirements during proposed test mining and bulk sampling activities.
Engineering designs for waste dumps, stockpiles and portal entry remain on schedule, with this work set to inform modifications to the Nevada reclamation permit.
The company expects to secure all required permits by mid-2027, after which it will determine timing for commencement of the exploration decline, test mining and bulk sampling programs.
Blackrock Silver aims to establish a domestic silver and gold supply through development of the Tonopah West Project, located in Nevada’s historical Queen of the Silver Camps.
