i-80 Gold stock surges on Ruby Hill drill results in Nevada

New results have intersected multiple stacked zones of mineralization in the southeast portion of the deposit.

Highlights from 2023 drilling at FAD include 4.4 g/t Au, 91.3 g/t Ag, 8.4% Zn & 0.3% Pb over 1.6 m, 4.9 g/t Au, 50.2 g/t Ag, 9.0% Zn & 0.2% Pb over 4.5 m, 6.2 g/t Au, 57.1 g/t Ag, 6.9% Zn & 0.1% Pb over 5.0 m; 6.0 g/t Au, 35.5 g/t Ag, 5.8% Zn & 0.2% Pb over 8.5 m and 3.1 g/t Au, 48.8 g/t Ag, 2.1% Zn & 1.3% Pb over 3.8 m.

An infill hole drilled on the western margin of the west FAD lobe returned 5.7 g/t Au, 159.4 g/t Ag, 15.0% Zn & 2.8% Pb over 5.4 m; 13.7 g/t Au, 430.0 g/t Ag, 15.9% Zn & 7.7% Pb over 2.5 m and 9.0 g/t Au, 92.4 g/t Ag, 12.2% Zn & 1.0% Pb over 14.6 m.

The Eureka District has a long and successful history of mining since 1864, including some of the world’s highest-grade CRD mines, the company said. 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.

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, i-80 said.

“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,” Tyler Hill, chief geologist of i-80 Gold said in a news release. “FAD is unusual in comparison to global CRD deposits given its elevated gold grades.”

The company’s stock surged over 10% in Toronto on Monday, with shares traded over 1.4 million times, compared with an average daily trading volume of 366,048. i-80 has a C$677 million ($504m) market capitalization.
