RUBY HILL

 

i-80 recently acquired a 100% interest in the Ruby Hill property, located within the Battle Mountain Trend, from Waterton Global Resource Management. The Ruby Hill property is host to a producing open pit mine and multiple deposits that contain substantial gold and silver resources, and potential for significant base metal mineralization. Processing infrastructure at Ruby Hill includes a CIL processing plant and leach pad & CIC circuit.  The Company will be advancing permitting for an underground mine to be constructed from the bottom of the current pit and mineralization is expected to be trucked to the Lone Tree Complex for processing. A major drill campaign will be carried out for the remainder of 2021 and into 2022 following which Technical (resource and economic) Studies will be completed.

TECHNICAL REPORTS

Ruby Hill Mineral Resource Estimate, Eureka County, Nevada (October 22, 2021)

GEOLOGY

The Ruby Hill Mine is located along the southeastern end of the Battle Mountain/Eureka gold trend. The Eureka District exposes a nearly continuous sequence of Cambrian and Ordovician carbonate units with subordinate shale and quartz sandstone. Polymetallic base metal deposits of Cretaceous age are located throughout the district and were some of the first deposits mined in the late 1800’s. The Blackjack target at Ruby Hill is a Cretaceous skarn deposit located on the margin of the Graveyard Flats stock. Mineralization at Blackjack is composed of coarse grained pyrite, sphalerite, and argentiferous-galena. During the 1990’s Homestake Mining Company discovered an oxidized Eocene Carlin-type ore body in the Goodwin Formation, with what would become the Archimedes pit. Later discoveries included the Ruby Deeps deposit characterized by Carlin-type sulphide breccias in the Windfall limestone and Dunderberg Shale. Like other Carlin-type systems gold at Archimedes and Ruby Deeps is located in the rims of arsenian-pyrite around pre-existing pyrite grains and is associated with silicification and decarbonatization.
