i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) is pleased to announce that drilling has identified new zone of high-grade gold mineralization in its first hole drilled to test a new target area at the Company’s 100%-owned Ruby Hill Property located in Eureka County, Nevada.
High-grade gold mineralization was intersected in the first hole drilled to test continuity of a historic intercept below the Archimedes pit. A historic hole (HC1428) drilled by Homestake Mining Company intersected 15.0 g/t Au over 5.5 m, however no additional drilling was ever completed. Late in the 2022 drill program, this target was tested with a step-out hole, iRH22-65, that intersected high-grade mineralization at the projected target depth (see Figures 1 & 2 and Table 1).
Highlight results from hole iRH22-65 drilled to test the 428 Zone:
The 428 Zone is located approximately 300 metres east of the southern portion of the Ruby Deeps Zone and is one of several brownfields exploration targets tested in the highly successful 2022 exploration program at Ruby Hill. This program resulted in multiple gold, polymetallic and base metal discoveries including the Hilltop Zones where drilling has returned significant high-grade carbonate replacement mineralization including 515.3 g/t Ag, 28.9 % Pb, 10.5 % Zn & 0.9 g/t Au over 28.3 m in hole iRH22-43 (Upper Hilltop). The 428 Zone is located below the Archimedes pit and appears to be a combination of distal-disseminated gold mineralization overprinted by later Carlin-type gold mineralization. The mineralization is hosted within the top of the Hamburg dolomite at the contact with overlying metamorphosed Dunderberg Shale with close proximity to the Blanchard fault. The Blanchard fault structure was one of the primary feeder structures of the multiple mineralized zones mined in the pit. No other holes have tested this contact in proximity to the Blanchard fault presenting a significant upside target at Ruby Hill. Additionally, the Hamburg dolomite represents a new host of Carlin-type mineralization on the Property and follow-up drilling will be completed during the ongoing 2023 exploration program.
“Our multiple discoveries made in 2022 highlight the potential of the mineralized system at Ruby Hill and confirm our model for the occurrence of multiple types of world-class, high-grade, deposits”, stated Tyler Hill, Senior Geologist of i-80. “Drilling is currently focused on expanding mineralization within the Hilltop Zones and the Blackjack horizon, both of which are located in close proximity to the underground infrastructure currently being planned and permitted”.
23 drill holes from the 2022 Ruby Hill drill program remain outstanding at assay labs and the Company expects to be in a position to provide an update from this drilling within a few weeks.

All samples were submitted to American Assay Laboratories (AAL) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through AAL are run through standard prep methods and analyzed using FA-Pb30-ICP (Au; 30g fire assay) and a custom multi-element package (35 element Suite; 0.5g 4-acid digestion/ICP-MS) methods. 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 were assayed by various accredited laboratories. Refer to the July 31, 2021, NI 43-101 Report on 2021 Ruby Hill Mineral Resource Estimate, Eureka County, Nevada, USA for information on historic assays.
