i-80 Gold Continues to Intersect High-Grade Gold in Expansion Drilling at Granite Creek

Including 15.3 g/t Au over 10.5m, 10.0 g/t Au over 10.2m, 13.6 g/t Au over 4.7m & 17.6 g/t over 3.0m

RENO, Nev., April 20, 2022 /CNW/ - i-80 GOLD CORP. (TSX: IAU) (OTCQX: IAUCF) ("i-80", or the "Company") is pleased to announce results from four of the final five holes of the Phase 1, 2021, drill program focused primarily on delineating the high-grade "South Pacific" extension horizon at the Company's Granite Creek Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada.

The South Pacific Zone ("SPZ") is a new zone of high-grade gold mineralization located immediately north of the underground mine workings at Granite Creek (see Figure 1). In 2021, sixteen (16) holes were completed in the SPZ, successfully defining multiple fault structures that are demonstrating continuity of mineralization over a strike length of approximately 600 metres and a dip length of approximately 250 metres and remain wide open for expansion along strike and at depth. Hole iGS21-20 intersected mineralization up-dip and to the south of previous drilling, closer to the underground workings where it remains open. Drilling in the SPZ horizon displays impressive gold grades and widths of mineralization and multiple mineralized horizons. Owing to the early success of the expansion drilling program, the ongoing 2022 program has been expanded to ~30,000m.

Final highlight results from 2021 drilling in the South Pacific Zone (and adjacent horizons):

• 13.8 g/t Au over 2.1 m & 25.2 g/t Au over 2.2m in hole iGS21-16
• 6.1 g/t Au over 2.9 m & 9.9 g/t Au over 2.5 m in hole iGS21-17
• 9.7 g/t Au over 4.0 m & 10.0 g/t Au over 10.2 m & 13.7 g/t Au over 5.6 m & 15.3 g/t Au over 10.5 m in hole iGS21-19
• 13.6 g/t Au over 4.7 m & 17.6 g/t Au over 3.0 m in hole iGS21-20

Drilling of the South Pacific Zone ("SPZ") is the primary target of the ongoing drill program with multiple drill rigs completing delineation drilling so that the zone will be included in a resource update following the 2022 program. The SPZ consists of multiple subvertical fault structures located within both the Upper and Lower Comus rock units. Most structures within the SPZ appear to trend north to northeast (see Figures 1 and 2). Step-out drilling to expand mineralization along strike and at depth is being completed in 2022.

"Drilling is demonstrating substantial high-grade resource potential in the South Pacific Zone, and it has elevated to our top priority target at Granite Creek", stated Ewan Downie, Chief Executive Officer of i-80.  "Owing to indications of improved ground conditions, significant upside, and proximity to existing underground workings, we have started to drive the decline deeper in order to expedite the development of the SPZ into our near-term mine plan."

High-grade mineralization at Granite Creek occurs in a near-identical geological setting as that at the multi‑million‑ounce Turquoise Ridge Mine located immediately to the north (see Figure 3); 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.

Additional work at Granite Creek includes development to access mineralization proximal to the underground workings, underground drilling and mining. i-80 entered into a toll agreement with Nevada Gold Mines so that refractory mineralization can begin to be trucked to its Twin Creeks facility for processing while Company retrofits its Lone Tree autoclave (see press release dated September 7, 2021).

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.

All samples were submitted to either ALS Minerals (ALS) or Paragon Geochemical Assay Laboratories (PAL) both of Sparks, NV, which are ISO 9001 and 17025 certified and accredited laboratories, independent of the Company. Samples submitted through PAL and ALS are run through standard prep methods and analyzed using FA-Pb30-ICP (Au; 30g fire assay) and 48MA-MS (48 element Suite; 0.5g 4-acid digestion/ICP-MS) methods for PAL and Au-AA23 (Au; 30g fire assay) and ME-ICP41 (35 element suite; 0.5g Aqua Regia/ICP-AES) for ALS. ALS and 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.

i-80 Gold Corp. is a well-financed, Nevada-focused, mining company with a goal of achieving mid-tier gold producer status through the development of multiple deposits within the Company's advanced-stage property portfolio to complement existing gold production from the Ruby Hill open pit.
