Granite Creek Underground Drilling Intersects High-Grade Gold Mineralization

Rhea-AI Summary

i-80 Gold Corp. announced promising results from its underground drilling at the Granite Creek Mine Property in Humboldt County, Nevada. Key highlights include high-grade gold mineralization such as 16.0 g/t Au over 33.9 m and 24.4 g/t Au over 14.6 m, primarily in the Ogee and Adam Peak zones. The ongoing drill program aims to delineate mineralization for mining and enhance resource estimates, contributing to a planned resource update after approximately 30,000 meters of drilling. The Company is simultaneously conducting metallurgical tests by delivering bulk samples to nearby Nevada Gold Mines.

Positive

• High-grade gold results, including 24.4 g/t Au over 14.6 m.
• Drill program focused on high-grade zones indicates potential for resource expansion.
• Initial bulk sample mining for metallurgical testing supports further development.

Negative

• None.

Highlight results include 16.0 g/t Au over 33.9 m and 24.4 g/t Au over 14.6 m

Reno, Nev., Aug. 3, 2022 /PRNewswire/ - i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) ("i-80", or the "Company") is pleased to announce continued positive results from the ongoing underground drill program at the Company's Granite Creek Mine Property ("Granite Creek" or "the 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:

• 8.6 g/t Au over 10.3 m (0.25 oz/ton Au over 33.7 feet) in hole iGU22-17 – Ogee Zone
• 18.4 g/t Au over 9.1 m (0.54 oz/ton Au over 30.0 feet) in hole iGU22-18 – Otto Zone
• 13.8 g/t Au over 5.7 m (0.40 oz/ton Au over 18.8 feet) in hole iGU22-26 – Range Front Zone
• 24.4 g/t Au over 14.6 m (0.71 oz/ton Au over 48.0 feet) in hole iGU22-30 – Adam Peak Zone
• 26.4 g/t Au over 5.0 m (0.77 oz/ton Au over 16.4 feet) in hole iGU22-42 – Ogee Zone
• 23.1 g/t Au over 5.0 m (0.67 oz/ton Au over 16.4 feet) in hole iGU22-43 – Ogee Zone
• 16.0 g/t Au over 33.9 m (0.47 oz/ton Au over 111.3 feet) in hole iGU22-45 – Ogee Zone

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.
