i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) is pleased to announce continued positive results from the ongoing underground drill program at the Company’s Granite Creek Mine Property located in Humboldt County, Nevada.
The 2022 underground drill program at Granite Creek is focused on delineating mineralization for mining and upgrading and expanding resources. In the upper parts of the mine, high-grade gold mineralization is being defined in the Otto/Adam Peak/Range Front horizons, while from the lower levels drilling is focused on defining mineralization in the Ogee Zone that is expected to be the primary zone in the near future (see Figure 1).
Highlight new results from 2022 underground drilling:
The underground zones at Granite Creek will be included in a resource update following the 2022 program that is expected to comprise approximately 30,000 meters of drilling from both surface, focused on the South Pacific Zone, and the underground Ogee, Otto and Adams Peak Zones. Table 1 provides a complete summary of new results from the 2022 underground drilling program.
The company is currently mining a bulk sample from the underground zones to deliver an initial 10,000 tons to Nevada Gold Mines’ nearby Twin Creeks Mine (See Figure 2) for a metallurgical test, as per the processing agreement, which will allow for the deposit to be developed and ramped up for continuous mining.
“The drill program continues to define high-grade mineralization over substantial widths, particularly within the Ogee Zone that remains open for expansion at depth”, stated Tyler Hill, Senior Geologist of i-80.
The Granite Creek Property is strategically located proximal to Nevada Gold Mines’ Turquoise Ridge and Twin Creeks mines at the north end of the Battle Mountain-Eureka Trend, at its intersection with the Getchell gold belt in Nevada. High-grade mineralization occurs in a near-identical geological setting as that at the multi-million-ounce Turquoise Ridge Mine located immediately to the north (see Figure 2); proximal to a major regional fault (the Getchell or Range Front fault) on the eastern edge of the large Osgood Mountains intrusive complex. The Granite Creek deposit remains open at depth and along strike from the existing underground workings.

QAQC Procedures
All samples were submitted to ALS Minerals (ALS) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through ALS are run through standard prep methods and analyzed using Au-AA23 (Au; 30g fire assay) and ME-ICP41 (35 element suite; 0.5g Aqua Regia/ICP-AES). ALS also undertakes their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. i-80 Gold Corp’s QA/QC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results.
