i-80 Gold Intersects 73.2 m of 7.4 g/t Au in Step-out Drilling at Granite Creek
Including 13.3 g/t Au over 13.1 m, 20.3 g/t AU over 7.5 m & 10.1 g/t Au over 17.5 m
Reno, Nevada, February 8, 2022 – i-80 GOLD CORP. (TSX:IAU) (OTCQX:IAUCF) (“i-80”, or the “Company”) is pleased to announce that exploration drilling at the Company’s Granite Creek Property (“Granite Creek” or “the Property”) located in Humboldt County, Nevada continues to provide impressive results in step-out drilling completed at multiple gold horizons.
The primary target of surface drilling is the South Pacific Zone where high-grade mineralization is being defined at depth below, and to the north of, the mine workings at Granite Creek (see press releases dated November 16, 2021, and February 2, 2022). This release provides results from additional targets being tested on the Property, including expansion drilling at depth below the Ogee Zone and assessing the down‑dip potential of mineralization contained within the Mag Zone (open pit). This drilling is part of the expanded 30,000 metre drill program from both surface and underground.
Initial highlight results from the Ogee and Mag Zone drilling include:
- Ogee Zone
- 7.4 g/t Au over 73.2 m including 13.3 g/t Au over 13.1 m, 20.3 g/t over 7.5 m & 10.1 g/t Au over 17.5 m in hole iGS21-15
- Mag Zone
- 3.4 g/t Au over 12.6 m in hole iGS21-02
- 2.0 g/t Au over 6.4 m in hole iGS21-13
- 3.4 g/t over 16.8 m and 1.8 g/t over 5.8 m in hole iGS21-14
- Ogee Zone
Surface drill hole iGS21-15 is the first hole to test the Ogee Zone at depth and represents one of the deepest holes drilled to-date at this target. Holes iGS21-02, 13 & 14 were designed to test the potential for sulphide mineralization below the proposed Mag open pit.
The Ogee Zone represents one of the primary zones currently being developed for underground mining and was partially mined in 2012 and 2013. Drilling from surface and underground is designed to elevate resources to reserves. Hole iGS21-15 is the first hole drilled to test the Ogee Zone, represents the deepest hole drilled into this target in the ongoing drill program, and intersected one of the widest intervals of mineralization, 7.4 g/t Au across 73.2 m, approximately 200 metres below the bottom Level of the mine. Higher grade intercepts within the broader interval include 13.3 g/t Au across 13.1 m, 20.3 g/t Au across 7.5 m, and 10.1 g/t Au across 17.5 m (see Table 1 and Figure 1 & 3).
This intercept continues to confirm the significant upside opportunity at Granite Creek and step-out drilling is being completed to expand mineralization along strike and at depth where the deposit remains open. The Ogee Zone is located immediately south of the South Pacific Zone (“SPZ”) that has been upgraded to the primary target of the 2022 program and where recent drilling has returned numerous high-grade intercepts including 25.5 g/t Au across 5.5 m, 16.3 g/t Au across 7.1 m and 11.0 g/t Au across 9.1 m (see Press Released dated Feb. 2, 2022). The Ogee Zone is hosted with the Lower Comus Formation rock unit along the east striking and steeply dipping CX West fault zone.
“Hole iGS21-15 was drilled to test with core, the down-dip extension of the Ogee Zone where a reverse circulation hole drilled by Barrick in the early 2000’s reported high-grade mineralization over an appreciable width”, stated Tyler Hill, Senior Geologist of i-80. “The core hole has confirmed a broad zone of high-grade mineralization and could represent an area of converging faults at depth with substantially increased widths. This could have significant implications on the upside opportunity at Granite Creek.”

The Mag Zone is one of the primary zones in the Company’s planned open pit development program at Granite Creek that is in the process of being permitted. With the recent acquisition of the Lone Tree processing facility, future work will also consider expanding the open pit zones at depth to access deeper sulphide mineralization. Three holes were drilled in 2021 to test mineralization below the Mag pit, all intersecting significant intervals of gold mineralization including 3.4 g/t Au across 12.6 m and 3.4 g/t Au across 16.8 m (see Table 2 and Figure 3).

Mineralization associated with the mag fault remains wide open for expansion at depth and could be considered as an opportunity to expand the mag pit or consider a decline from the bottom of the pit to access higher-grade areas. The Mag Zone is hosted within the Upper Comus Formation rock unit in the footwall of the northwest striking and northeast dipping Mag fault.

High-grade mineralization at Granite Creek occurs in a near-identical geological setting as that at Nevada Gold Mines’ (“NGM”), multi-million-ounce Turquoise Ridge Mine that is located immediately to the north (see figure 4); 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.

All samples were submitted to Paragon Geochemical Assay Laboratories (PAL) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through PAL are run through standard prep methods and analysed using FA-Pb30-ICP (Au; 30g fire assay) and 48MA-MS (48 element Suite; 0.5g 4-acid digestion/ICP-MS) methods. PAL also undertake 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. Historic holes were assayed by various accredited laboratories. Refer to the November 9th, 2021 Granite Creek Mine Project Preliminary Economic Assessment NI 43-101 Technical Report for information on historic assays.
