Blackjack Zone – 19.14 % Zn, 0.4 g/t Au & 29.2 g/t Ag over 30.4 m

East Hilltop Zone – 20.8 % Zn & 15.0 g/t Ag over 11.6 m and 235.5 g/t Ag, 5.7 % Pb, & 7.0 % Zn over 14.0 m

i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) is pleased to report additional positive results from exploration drilling at the Company’s 100%-owned Ruby Hill Property located in Eureka County, Nevada. The 2023 program continues to expand high-grade polymetallic mineralization in multiple zones and has resulted in new discoveries.

While awaiting approvals (now received) for additional land disturbance permitting the Company to construct road and drill pads for the expansion of the exploration program along the Hilltop Corridor, drilling has been focused on the Blackjack deposit and also the East Hilltop Zones. These zones were discovered late in the 2022 program (East Hilltop skarn) and early in 2023 (East Hilltop CRD). Drilling in 2023 has intersected high-grade mineralization in multiple target areas including in step-out drilling where mineralization remains wide open for expansion. Table 1 provides a summary of recent drill results and recent highlight results include:

• Blackjack Zone
  • 19.14 % Zn, 0.4 g/t Au & 29.2 g/t Ag over 30.4 m (iRH23-18A)

“Drilling at Ruby Hill continues to return results that confirm the Property’s capability to be a flagship asset for i-80 with high-grade polymetallic base metal mineralization occurring immediately adjacent to the high‑grade Ruby Deeps gold deposit.”, stated Tyler Hill, Chief Geologist of i-80. “Our drill program demonstrates significant potential to expand mineralization with all zones open for expansion and multiple high-priority anomalies identified from geophysical surveys remain untested.”

In addition to drilling, geophysical surveys are being completed to cover the Hilltop Corridor to the FAD deposit that was acquired earlier in the year with the takeover of Paycore Minerals. Multiple anomalies have been identified for follow-up exploration.

Drill Program

In mid-2022, the Upper Hilltop Zone was discovered with an intercept of 515.3 g/t Ag, 28.9 % Pb, 10.5 % Zn and 0.9 g/t Au over 28.3 m in hole iRH22-43 (see press release dated August 30, 2022). This led to the definition of multiple polymetallic CRD and skarn zones to the south of the Blackjack deposit, on the south side of the Archimedes pit, situated along the Hilltop fault structure. Mineralization has now been defined over a strike length of approximately 750 metres including the Upper, Lower and East Hilltop Zones (see Figures 1 & 2). Current drilling is focused on the Blackjack and East Hilltop Zones until new drill set-ups are constructed for delineation and expansion drilling and to resume definition of the Upper Hilltop Zone.

Blackjack Zone – The Blackjack deposit was identified by previous owners, Homestake and Barrick, immediately under the Archimedes pit when poly-metallic skarn mineralization was discovered below the Archimedes pit (see Figure 1). Due to its location beneath an inaccessible area in the pit, the Company is utilizing directional core drilling to upgrade Blackjack to resource status.

Step-out drill hole iRH23-18A extends mineralization to the south with the most impressive skarn intercept received to date since i-80 commenced drilling at Ruby Hill. New intercepts from the 2023 drill program include:

• iRH23-18A – 19.4 % Zn, 29.2 g/t Ag and 0.4 g/t Au over 30.4 m
• iRH23-29 – 17.8 % Zn, 59.8 g/t Ag and 0.9 g/t Au over 16.4 m

Recent drilling in the Blackjack Zone has also identified CRD mineralization in drilling in the upper central portion of the deposit (assays pending). The Blackjack deposit occurs to the west of the Graveyard Flats intrusive and is underlain by Carlin-type gold mineralization (Lower Jack), neither of which are part of the current mineral resource at Ruby Hill.

East Hilltop Skarn – Late in the 2022 drilling program, high-grade skarn mineralization was discovered in the East Hilltop target area with an intercept of 12.3 % Zn over 39.6 m (see press release dated Dec. 19, 2022, and Fig. 1). This mineralization is located to the south of, and in a near-identical geological setting as the Blackjack deposit. Follow-up drilling continues to expand skarn mineralization at East Hilltop and has also discovered high-grade CRD mineralization. New intercepts in the East Hilltop skarn zone include:

• iRH23-16 – 12.5 % Zn & 5.7 g/t Ag over 5.0 m – hole lost prior to main zone
• iRH23-16A – 12.8 % Zn & 4.6 g/t Ag over 10.7 m – wedge hole – main zone
• iRH23-27 – 11.6 % Zn & 5.8 g/t Ag over 6.1 m AND 14.7 % Zn & 3.7 g/t Ag over 4.6 m
• iRH23-30 – 20.8 % Zn & 15.0 g/t Ag over 11.6 m

East Hilltop CRD – Early in the 2023 drill program, high-grade CRD mineralization was discovered to the east of the Upper Hilltop Zone and proximal to the East Hilltop Skarn Zone with an intercept of 9.7 % Zn, 10.0 % Pb and 226.1 g/t Ag over 8.4 m in hole iRH23-10 (see press release dated April 25, 2023 and Figure 1). New hole iRH23-26 was drilled to follow-up the initial discovery, returning high-grade mineralization, and ongoing drilling continues to expand CRD mineralization at East Hilltop with assays pending. Hole iRH23-26 intersected multiple zones of mineralization including:

• 6.8 % Zn, 3.6 % Pb, 0.9 g/t Au & 136.3 g/t Ag over 9.1 m
• 10.4 % Zn, 7.1 % Pb, 0.6 g/t Au & 257.2 g/t Ag over 4.6 m
• 7.4 % Zn, 7.3 % Pb, 1.0 g/t Au & 323.5 g/t Ag over 6.1 m

Tyche Zone – High-grade gold-sulphide mineralization was discovered during the current program in a previously untested area along the contact of the Graveyard Flats intrusive (stock). Exceptional high-grade gold mineralization assaying 45.4 g/t Au and 50.2 g/t Ag over 17.5 m was intersected in drill hole iRH23‑18A (see press release dated August 2, 2023 and Figure 1). Once new drill set-ups are constructed, the Company plans to complete additional follow-up drilling to better assess the potential of this high-grade target.

FAD Zone – Drilling is also underway at the FAD deposit which was secured through the acquisition of Paycore Minerals earlier in 2023. Delineation and expansion drilling is being completed in advance of a revised resource estimate. Drilling completed to-date has returned multiple intervals of visually impressive massive sulphide mineralization (assays pending) that compliment previous drilling completed by Paycore that demonstrate significant potential to expand mineralization in the East Lobe, which continues to remain open for expansion. Paycore drilling returned intercepts of 8.0 g/t Au, 79.0 g/t Ag, 10.0 % Zn & 1.0 % Pb over 27.4 m in hole PC22-10, 7.1 g/t Au, 376.0 g/t Ag, 6.3 % Zn & 10.3 % Pb over 14.8 m in hole PC22‑08 and 1.1 g/t Au, 155.0 g/t Ag, 22.0 % Zn & 1.5 % Pb over 12.5 m in hole PC22-07.

TL Target (Exploration) – While awaiting approvals to expand the drill program onto the BLM lands, eight of the listed holes were drilled to test for potential mineralization in the vicinity of the historic TL Mine. These holes generally intersected narrower widths of modest grade CRD mineralization with highlight intercepts of 0.3 g/t Au, 236.0 g/t Ag, 0.7 % Zn and 5.7 % Pb over 3.1 m (iRH23-13) and 8.5 g/t Au, 85.5 g/t Ag, 0.9 % Zn and 7.3 % Pb over 3.0 m (iRH23-21).

Geophysical Surveys

Previous geophysical surveys (MT, gravity and magnetic) have identified several highly perspective anomalies that are believed to have the potential to represent additional massive sulfide targets including the Spring Valley and Deep Blue anomalies. Several of these surveys stopped at the south side of the Archimedes pit and are now being extended to cover the southern extension and the recently acquired FAD Property including the largely untested Hilltop Corridor.

The Hilltop Corridor is a 1.5 km long, alluvial covered, trend immediately south of the Archimedes pit. It is believed to be host to multiple feeder fault structures and is largely untested by previous drilling owing to the alluvial cover. The identification of a major northwest striking fault structure that is closely associated with the discovery of the Hilltop Zones confirms the Company’s geological teams’ model that the Ruby Hill Property could be host to multiple types of mineralization and several large-scale deposits.

The Eureka (Ruby Hill) Mining District has a history of high-grade polymetallic CRD production that began in the 1860’s and spanned a period of more than one hundred years. Historic mined grades rank amongst the highest for any

CRD district in the world. Since the 1960’s, the CRD potential of the Eureka District has been largely overlooked in favour of exploration for Carlin-type gold deposits and the Company considers the opportunity to be substantial. The Ruby Hill Property is one of the Company’s primary assets and is host to the core processing infrastructure within the Eureka District of the Battle Mountain-Eureka Trend including an idle leach plant, an active heap leach facility, and is host to multiple gold, gold-silver and polymetallic (base metal) deposits.

Multiple types of mineralization have been identified in the Hilltop Corridor including skarn (Blackjack), CRD (Hilltop/historic mines), distal disseminated Au-Ag (Mineral Point), Carlin-type gold (Ruby Deeps/428/Lower Jack) and more recently gold-sulphide (Tyche).

The Company has submitted for approval its plan to develop an underground mine at Ruby Hill with mineralization accessed via a ramp from the Archimedes open pit. Work is also progressing for the completion of updated mineral resource estimates (gold and polymetallic zones) and an initial economic study for the gold zones (only).
