Reno, Nevada, January 25, 2024 – i-80 GOLD CORP. (TSX:IAU) (NYSE:IAUX) (“i-80”, or the “Company”) is pleased to announce high-grade results from the 2023 drill program completed at the FAD deposit situated on the Company’s 100%-owned Ruby Hill Property (“Ruby Hill” or “the Property”) located in Eureka County, Nevada.

FAD is one of several polymetallic deposits drilled at Ruby Hill in 2023 for the completion of initial resource estimates for the FAD, Blackjack and Hilltop deposits. The Ruby Hill Property represents the core land package within the Eureka District of Nevada, one of the world’s premier re-emerging Carbonate Replacement Deposit (CRD) districts. FAD is a high-grade polymetallic deposit and is expected to add to the Company’s already impressive resource base. New results have intersected multiple stacked zones of mineralization in the southeast portion of the deposit.

The Eureka District has a long and successful history of mining, extending over a period of one hundred sixty years (1864-Present) including some of the world’s highest-grade CRD mines. From 1866 until 1967 the Ruby Hill district produced an estimated 2 Mt of ore containing approximately 1.65 Moz Au, 39 Moz Ag, and 625M lbs of lead. It is estimated 80% to 90% of this production came from the original Ruby Hill Mine, located 500 metres southwest of the FAD deposit[i].

The FAD deposit Is located in the hanging-wall of the Ruby Hill fault and is comprised of dominantly sulfide, polymetallic mineralization (see Figure 2). Drilling completed in 2022 and 2023 has successfully intersected multiple horizons of mineralization that remain open for expansion. Results compliment previously released holes drilled by Paycore that include:

  • 7.8 g/t Au, 155.5 g/t Ag, 22.0% Zn & 1.5% Pb over 12.5 m (PC22-07)
  • 7.1 g/t Au, 376.3 g/t Ag, 6.3% Zn & 10.3% Pb over 14.8 m (PC22-08A)
  • 8.0 g/t Au, 79.1 g/t Ag, 10.2% Zn & 1.0% Pb over 27.4 m (PC22-10)

In addition to the deeper sulfide mineralization at FAD, drilling tested proximal to the historic Ruby Hill Mine. These holes intersected low-grade oxide mineralization suggesting the potential to delineate near-surface mineralization proximal to historic workings that may be amenable to open pit mining.

“The drill program at FAD compliments successful programs on the Blackjack and Hilltop deposits and our expanded focus on exploring for polymetallic mineralization in the Eureka District to better assess the economic opportunity.”, stated Tyler Hill, Chief Geologist of i-80 Gold. “FAD is unusual in comparison to global CRD deposits given its elevated gold grades.”

The FAD deposit is located within the “Hilltop Corridor” approximately 2 km south of the Hilltop discovery made by i-80 in mid-2022. Multiple drill rigs were active in 2023, aggressively defining and expanding mineralization at Hilltop, now having identified a series of high-grade CRD zones located on the south side of the Archimedes pit (see Figure 1).  Previously released results from drilling at Upper Hilltop include 515.3 g/t Ag, 28.9 % Pb, 10.5 % Zn & 0.9 g/t Au over 28.3 m in hole iRH22-43, 1.9 g/t Au, 631.3 g/t Ag, 7.4 % Zn & 33.0 % Pb over 18.3 m in hole iRH22-53, 14.7 g/t Au, 253.3 g/t Ag, 0.4% Zn & 8.7% Pb over 7.5 m in hole iRH23-52 and 0.6 g/t Au, 332.9 g/t Ag, 8.8% Zn & 18.8% Pb over 32.0 m in hole iRH23-54. Recent results from drilling in the East Hilltop Zone include 1.5 g/t Au, 274.6 g/t Ag, 4.7% Zn & 4.3% Pb over 13.2 m in hole iRH23-48, and 9.5% Zn, 0.3% Cu & 12.6 g/t Ag over 114.3 m including 17.7% Zn, 0.4% Cu & 10.2 g/t Ag over 36.6 m in iRH23-50.

The Hilltop Corridor is a 2 km long (see Figure 1), alluvial covered, trend immediately south of the Archimedes pit believed to be host to multiple feeder fault structures that is largely untested by previous drilling owing to the alluvial cover. The Hilltop discoveries were made in the second half of 2022 exploration campaign while testing one of several generative exploration targets identified proximal to the Blackjack (skarn) deposit, with mineralization defined along the Hilltop fault structure over a strike length of approximately 750 metres.  At the end of the 2023 drill program, one hole was drilled to test for the possible extension of skarn mineralization proximal to the contact of the Graveyard Flats intrusive. This hole, iRH23‑­­55, intersected a broad zone of skarn mineralization with 4 higher-grade intercepts, including an interval of 1181.0 g/t Ag, 19.5% Zn, 10.2% Pb & 1.2% Cu over 1.5 m.

Drilling was also completed in the Blackjack deposit in 2023, yielding numerous significant results, successfully delineating and expanding high-grade mineralization. i-80 drilling started at hole PC23-22.
