New El Nino Drill Results Include 14.05 g/t Au Over 25.9 m

RENO, Nev., April 21, 2021 /PRNewswire/ - i-80 GOLD CORP. (TSX: IAU) ("i-80", or the "Company") is pleased to provide an update for its 40%-owned South Arturo Property located in the Carlin Trend of Nevada. South Arturo is a joint venture with Nevada Gold Mines ("NGM") and includes the high-grade El Nino underground mine, which is in production.

Work completed in 2020 included a successful expansion drill program at El Nino as well as work targeting the advancement of two additional development opportunities on the property; the Phase 1 open pit and the Phase 3 project.

El Nino

The 3,800 metre drill campaign completed in 2020 from underground drilling stations demonstrated the ability to extend mine life at depth with numerous high grade intercepts (previously released) including 26.76 g/t Au across 18.3 m, 17.11 g/t Au across 39.6 m and 5.73 g/t Au across 100.6 m. Additional highlight results from new results received from the 2020 program are provided below. Following up on the success of this drill program, more than 8,000 meters of exploration drilling are planned in 2021 focused on extending mineralization further down dip at the Lower El Nino and Cloud Nine targets.

Highlight assay results for previously unreleased intercepts from the 2020 drill program include:

19.8 m of 12.20 g/t Au (SEC20012)
29.0 m of 6.20 g/t Au (SEC20014)
25.9 m of 14.05 g/t Au (SEC20015)

Development of a ramp to access the deeper mineralization is under way and is expected to be completed in Q1 2023. Production of orebodies accessed from the ramp is expected to begin in Q2 2022.

Phase 1

More than 3,500 metres of drilling was completed on the near surface portion of the planned Phase 1 open pit to increase confidence in the ore reserves and upgrade mineral resources. This drilling returned higher than expected grade-thicknesses and Barrick has moved heap leach material from Phase 1 into their year–end 2020 mineral reserves. In 2021, the joint venture plans to complete further metallurgical work in advance of mine construction.

Phase 3

2020 drilling completed in the Phase 3 project area also returned favorable results and the joint venture partners have commenced trade-off studies to optimize the economics of the project as an underground versus open pit project, or a combination scenario. Initial work on the underground option has been encouraging and 3,500 metres of exploration drilling is planned to test the Hendrix target located between the El Nino and Phase 3 deposits.

"El Nino continues to deliver excellent results as demonstrated by the latest intercepts of our 2020 drill campaign. Multiple holes intersected zones of impressive grade over a mineable width", stated Matt Gili, President and COO of i-80 Gold. "We expect to see these results incorporated into an updated mineral resource model expected later in 2021. The deposit remains open at depth and along strike".
