Title: Update on the Toiyabe Gold Exploration Project, Lander County, Nevada

The Elko GSN Chapter is happy report that we set an in-person attendance record for the season with over 65 people enjoying David Ernst’s talk on Bald Mountain last month. It was a great talk and event! Additionally, we kicked off the year by announcing the Elko GSN Scholarship for the 2022-2023 academic year, please direct students to https://www.gsnv.org/chapters/elko/.

To keep the year rolling with excitement we are honored to have Dave Browning of Westward Gold Inc give an update on the Toiyabe Gold Exploration Project in Lander County, NV. The event is graciously sponsored by TonaTec Exploration, LLC.

Abstract:

The Toiyabe Gold Exploration project is part of a recently consolidated land package by Westward Gold located approximately 75 miles southwest of Elko, NV, within the Battle Mountain-Eureka Trend in Lander County, Nevada. The district-scale land package covers a ~39 km2 area consisting of the Toiyabe Exploration project, the Turquoise Canyon project immediately adjacent to the east, and the recently acquired adjoining East Saddle project to the south of the Toiyabe and Turquoise Canyon projects.

  A carbonate window consisting of the Devonian Horse Canyon and Wenban Formations crops out at surface on the Toiyabe project and is juxtaposed against upper plate Valmy and Slaven Formations which extend east into the Turquoise Canyon project.  The project is immediately north and east of the neighboring Toiyabe open pit mine, operated by Inland Gold and Silver which produced 89,000 oz Au between 1987 – 1991 via heap leach operation.  A 2009 NI 43-101 report outlined a ~173k oz Au historical resource estimate at the Toiyabe Exploration project known as the Courtney resource.

Previous exploration in the area began in 1964 and was largely focused south of the current Toiyabe Exploration claim block.  Drilling on the Toiyabe Gold Exploration project took place between 1979-1991 by various companies and 2005-2016 by Golden Oasis. Mineralization at the Toiyabe Mine and at the Courtney Resource consists of microscopic gold typical of Carlin-type gold deposits.  The main host rocks are lower plate carbonate rocks of the Devonian Horse Canyon, Devonian Wenban, and Silurian Roberts Mountains Formations below, within, and above the Roberts Mountains Thrust. Alteration associated with mineralization includes silicification as both veins and replacement, decalcification, oxidation, and remobilized carbon.

Data from past exploration has been consolidated and integrated with modern exploration methods completed in 2021, including a new IP survey, hyperspectral core imaging, and a hyperspectral airborne survey. Upcoming field work and drill programs aim to further test mineralization at the Toiyabe project, while exploring the lateral extent of the buried lower plate carbonate host rocks.
