i-80 Gold Intersects High-Grade Gold in Underground Drilling at

Granite Creek

Including 41.3 g/t Au over

7.1 m

& 16.0 g/t Au over

RENO, Nev.

Oct. 28, 2021

/CNW/ -

i-80 GOLD CORP.

(TSX: IAU) (OTCQX: IAUCF)

("i-80", or the "Company")

is pleased to

announce positive initial assay results from the ongoing underground drill program at the Company's Granite Creek Property ("Granite

Creek" or "the Property") located in

Humboldt County, Nevada

.

High-grade results from drilling from the 4740 Level targeting mineralization in the Otto and Adam Peak fault horizons proximal to and

below existing mine workings confirm consistency of mineralization in one of the initial areas being defined for underground mining (see

Table 1). When combined with historic high–grade drilling in this area, that returned numerous high-grade results including

20.8 g/t Au

over

6.1 m

in hole PRC-13-084 and 17.8 g/t Au over

6.1 m

in hole APRF-225

, a continuous zone of mineralization is being defined

that remains open at depth (see Figure 1). The Otto fault horizon is one of the multiple target areas being drilled, and several holes

intersected gold mineralization in multiple horizons. The current program is expected to comprise more than 20,000 metres (m) from

surface and underground with continued assay results to be provided as received.

Highlight results from initial underground drilling from Level 4740 include:

41.3 g/t (grams per tonne) Au (gold) over

7.1 m

in hole iGU21-07

11.0 g/t Au over

3.4 m

& 16.5 g/t Au over

3.0 m

in hole iGU21-08

16.0 g/t Au over

7.3 m

in hole iGU21-09

11.3 g/t Au over

4.6 m

in hole iGU21-11

10.5 g/t Au over

3.8 m

in hole iGU21-12

17.5 g/t Au over

2.3 m

& 17.6 g/t Au over

2.0 m

in hole iGU21-14

The primary goal of the 2021 drill program is to advance underground and open pit opportunities to production. It is expected that

refractory mineralization from the underground operation at Granite Creek will initially be trucked to Twin Creeks for processing,

pursuant to the agreement recently entered into with

Nevada Gold Mines

, until such time that the Company's

Lone Tree

facility is

operational. A Preliminary Economic Assessment for Granite Creek is nearing completion and expected to be released in the near

future.

Tyler Hill

, Senior Geologist of i-80, commented: "These results confirm the high-grade opportunity that we are developing at Granite

Creek and demonstrate excellent continuity of mineralization within the Otto and Adam Peak fault horizons that appear to broaden with

depth. Step-out drilling is being completed along strike and at depth, and we have intersected strong alteration and faulting in most

holes drilled to-date".

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; 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 and step-out drilling aimed at expanding resources is currently underway.

The majority of the ongoing program, expected to consist of more than 20,000 metres of drilling, is focused on defining and expanding

mineralization within several high-grade target areas proximal to existing underground mine workings at Granite Creek. i-80 has

completed initial underground rehabilitation and has commenced underground drilling. As part of an aggressive plan to re-commence

mining from underground, the Company is in the process of rehabilitating several areas for the purposes of commencing test mining in

H2-2021.

QAQC Procedures

All samples were submitted to either American Assay Laboratories (AAL) 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 AAL 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 and AAL 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 PRC-13-084 and

APRF-225 were assayed by Inspectorate American Laboratories (IAL) in

Sparks, NV

, which was an ISO 9002 accredited facility.

Samples submitted through IAL and were run through standard prep methods and analysed using a 30 gram fire assay. Historic hole

BRFC-026 was assayed by AAL with standard prep methods and analysed using a 30 gram fire assay.
