A Little Known Explorer Sits Near Major Gold Deposits (Ad)

Barrick Mining has spent decades building one of the world's great gold districts in Nevada, anchored by Fourmile, Goldrush, and Cortez Hills, a region that could hold as much as 60 million ounces of gold. Bordering Fourmile and less than a mile from Goldrush sits a little-known explorer now moving from historical data toward active exploration, setting targets and preparing for a maiden drilling program. With gold trading near record highs, this could be a pivotal stage for an overlooked name in the district.tc pixel
