PolarX has expanded its ground holding in Nevada, pegging an additional 96 mining claims across the Fourth of July prospect area in the gold-rich Humboldt Range. The new leases provide the company with contiguous coverage along more than 6 kilometres of strike, taking in a host of historical mine workings which have returned assays of up to 15.28 grams per tonne gold and an incredible 2639.3 g/t silver.
