The Green Springs gold project is located at the southern end of Nevada’s prolific Carlin Trend, 60 km southwest of the historic mining centre of Ely, Nevada in a region hosting numerous producing and past producing Carlin-type gold deposits. Green Springs is approximately 10 km east of Calibre Mining’s Gold Rock Project, 10 km south of Waterton’s Mt. Hamilton gold deposit and 20 km southeast of Calibre Mining’s producing Pan Mine. Other deposits/past producers in the region include Illipah (Calibre) and Griffon (Freemont Gold). The Bald Mountain mine complex operated by Kinross Gold is located 45 km to the north of Green Springs.
The Green Springs gold project hosts a past producing heap-leach gold mine that produced 74,000 ounces of gold from a series of shallow pits, less than 100 metres deep, at an average grade of 2.32 g/t Au in the late 1980’s for US Minerals Exploration (USMX).

The Green Springs gold project is located at the southern end of Nevada’s prolific Carlin Trend, 60 km southwest of the historic mining centre of Ely, Nevada in a region hosting numerous producing and past producing Carlin-type gold deposits. Green Springs is approximately 10 km east of Calibre Mining’s Gold Rock Project, 10 km south of Waterton’s Mt. Hamilton gold deposit and 20 km southeast of Calibre Mining’s producing Pan Mine. Other deposits/past producers in the region include Illipah (Calibre Mining) and Griffon (Fremont Gold). The Bald Mountain mine complex operated by Kinross Gold is located 45 km to the north of Green Springs.
The property hosts a widespread and shallow Carlin-type gold system, hosted within Mississippian rocks of the Chainman and Joana limestone formations, associated with de-carbonatization, silicification, jasperoid development, and typical pathfinder elements including Arsenic, Antimony, Mercury, and Thallium.
Gold mineralization has also been intersected in limited drilling at the Pilot Shale – Guilemette Limestone contact. This new target horizon is interpreted to be present across the property at a shallow depth and represents a compelling exploration opportunity.
