Blackrock’s flagship Tonopah West project consolidates the western half of the famed Tonopah Silver District within the Walker Lane trend of Nevada.  Known as the Queen of the Silver Camps, the Tonopah Silver District produced over 174 million ounces of silver and 1.8 million ounces of gold from approximately 7.5 million tonnes of high-grade silver-gold making it one of the most significant silver-gold districts in North America.  As the first group to target the historic workings on the property since production shut down nearly 100 years ago, Blackrock has since completed in excess of 150,000 metres of exploration drilling since 2020, making this the most active silver exploration project in North America.    The project hosts a stope optimized inferred maiden resource estimate of 2.97 million tonnes at a block diluted grade of 208 grams per tonne (g/t) silver (Ag) and 2.5g/t gold (Au) for a total inferred mineral resource of 19,902,000 ounces Ag and 238,000 ounces Au, or 446 g/t silver equivalent (AgEq) for 42.6 million oz AgEq, making Tonopah West one of the highest-grade undeveloped silver projects in the world.  A fully-funded resource expansion drill program is underway.
