Abstract:

The Eureka district located in central Nevada was one of the first significant mining districts in the state with ore discovered in 1864. The ore bodies consisted of oxidized Au-Ag-Pb carbonate replacement deposits (CRD) hosted in Ordovician to Cambrian carbonates. Production of these ores continued through the mid 1900s with an estimated 1.65 Moz of Au, 39 Moz of Ag, and 625 Mlbs of Pb produced from just 2.0 Mt, however this production is likely understated. Exploration by Homestake Mining in the 1990s resulted in the discovery of oxidized distal disseminated ore at Mineral Point and oxidized Carlin-Type ore at Archimedes. Ultimately a combination of Homestake, Barrick, Waterton, and i-80 Gold have produced ~1.5 Moz Au from the Archimedes pit. Additional exploration by Homestake and later Barrick, identified high-grade sulfide Carlin-Type mineralization at depth (Ruby Deeps), as well as a zinc skarn deposit (Blackjack). i-80 Gold acquired the Ruby Hill property from Waterton in October of 2021 and has conducted significant exploration since that time. A 25,000 meter exploration campaign has focused on infill and step-out drilling of the Ruby Deeps, 426 zone, and additional targets across the property. Follow-up drilling on historic Homestake and Barrick holes south of the Archimedes pit has resulted in the discovery of new CRD mineralization, with the discovery hole intersecting 28.3 m of 515 g/t Ag, 28.9% Pb, and 10.5 % Zn immediately beneath alluvium. Additionally, a new zone of zinc skarn has been discovered 400 m south of the Archimedes pit with an intercept of 39.6 m of 12.3% Zn. A revised resource estimate for the property is expected to be published in Q1, 2023 and permitting is underway for an exploration decline out of the Archimedes pit.

 

Tyler Hill Bio:

Tyler Hill is a Senior Geologist with i-80 Gold Corp. He received a B.S. degree in geology from Ball State University and a M.S. degree from the University of Nevada – Reno where he studied time-space relationships between Eocene magmatism and Carlin-style mineralization at Kinsley Mountain in eastern Nevada. After graduating, he worked with Premier Gold on the McCoy-Cove property during the discovery of the Gap deposit and also worked on the Goldbanks-Rye low sulfidation epithermal system in a joint-venture with Kinross. Since the formation of i-80 Gold, he has overseen exploration at the Granite Creek, Ruby Hill, McCoy-Cove, and Lone Tree properties.
