London BTC Company (LSE:BTC) has staked its fourth US gold project, Black Star, in Pershing County, Nevada, after due diligence sampling returned surface grades of up to 16.23 g/t gold and 49 g/t silver.
The Bitcoin miner and treasury company has been building a Nevada gold portfolio alongside its core digital-asset operations, and Black Star marks its third project in the northern part of the state.
Schiehallion Consulting, the company's geological adviser, collected 19 rock chip samples in June, with five of nine mineralised samples grading above 8 g/t gold across two target areas spanning 2.5 kilometres.
The project covers 744 acres across 36 unpatented mineral claims, sitting 16 miles from Hycroft Mine, which holds 16.4 million ounces of gold and 562.6 million ounces of silver in measured and indicated resources.
Historical workings at Black Star, including shafts and adits, saw only exploration in the 1980s, with no modern systematic work recorded.
"Black Star has the characteristics of a highly prospective exploration project and we're excited to commence the next phase of work," said Hewie Rattray, chief executive.
David Lenigas, chairman, said the pace of portfolio-building "speaks for itself" and pointed to further updates as follow-up work and additional staking proceed.
The company plans systematic rock-chip sampling and geological mapping across the underexplored corridor between the two target zones, alongside continued staking in Nevada and Arizona.
