Keystone Polymetallic Project

Western Ridge Resources’ flagship Keystone Polymetallic Project is located along the emerging Pershing Trend in Nevada, USA, near the major regional centre of Winnemucca, in the heartland of North American mining and within a well-established, supportive jurisdiction.

Keystone represents a unique combination of historically high-grade polymetallic mineralisation and district-scale exploration potential. The project comprises a substantial deeded landholding with multiple priority targets and sits within a proven mining corridor that has produced, and continues to produce, silver, gold, lead, zinc and tungsten.

Previous operations at Keystone demonstrated very high silver grades, in conjunction with zinc and lead mineralisation. Historic production records show 36,000 ounces of silver being produced from only 1,500 tonnes of ore material; for an average silver grade in excess of 1,000 g/t Ag. Historic reports from one of only two recorded drillholes on the property also show skarn mineralisation similar to the adjacent Springer mine complex, with WO₃ grades ranging between 0.5 – 2.25% over a 7 metre interval. Despite these excellent historical results, the project has not benefited from modern exploration techniques for more than 80 years.

Western Ridge is applying contemporary technical expertise and disciplined, systematic exploration to unlock this district-scale opportunity. The project is well supported by established infrastructure, with direct access to power, water and road connections from a major local highway.

The growth potential of Keystone is underpinned by its demonstrated historical grades and geological pedigree, positioning Western Ridge to advance the first modern exploration campaign at this historically productive site in decades.
