i-80 GOLD CORP. (i-80, or the company) announced the results of Metallurgical work completed by Blue Coast Research Ltd. (BCR) on samples from the company's Ruby Hill and Golden Hill (FAD) Projects located in Eureka County and along the southeastern end of the Battle Mountain/Eureka gold trend in Nevada. The Properties are host to multiple polymetallic base metal deposits and/or zones of mineralization that are being advanced by the company concurrent with the gold deposits.

The BCR Study was commissioned to enhance the understanding of the various deposits for planning purposes related to the recovery of the multiple metals contained within each zone. Locked cycle testing was completed on sulphide dominant composites from the Hilltop (Upper, Lower and East), and the FAD (East, West and Gold Hill Oxide) Zones. Highlights from the company's 2023/2024 metallurgical programs include: High grade zinc and/or lead concentrates were produced with positive recoveries for each of the four sulphide dominant composites ­ with zinc recoveries of up to 96.0%, lead recoveries of up to 97.9% and silver recoveries of up to 85.0%; Positive gold recoveries from cyanidation were achieved for the upper oxidized mineralized zones, realizing 86.8% for Upper Hilltop and 85.1% for Golden Hill; Notably, the composites contain low silica and low deleterious metals, enhancing the expected potential of future concentrates; Work in 2024 will include additional metallurgical work on the Mineral Point deposit at Ruby Hill that is host to a measured and indicated resource of 3.2 M ounces of gold and 97.5 M ounces of silver (203.2 M tonnes, 0.49 g/t Au, 14.9 g/t Ag) and an inferred resource of 1.9 M ounces of gold and 72.3 M ounces of silver (157.3 M tonnes, 0.37 g/t Au, 14.3 g/t Ag).

This makes it one of the largest gold/silver deposits in the United States.
