i-80 Gold Drilling Returns Best Intercept To-Date in the South Pacific Zone at Granite Creek 16.3 g/t Au over 15.7m and 33.7 g/t over 3.7m in hole iGS21-18
i-80 Gold Corp. announces significant results from its Phase 1, 2021 drilling at the Granite Creek Property in Nevada, identifying high-grade gold mineralization in the South Pacific Zone (SPZ). A total of 16 holes were drilled, confirming mineralization continuity over 600 metres. Notable results include 16.3 g/t Au over 15.7 metres from hole iGS21-18. The ongoing drilling aims to expand this high-grade zone, with a resource update anticipated after the 2022 program. The SPZ is strategically located near prominent gold mines, enhancing its exploration potential.
- High-grade gold mineralization confirmed in South Pacific Zone with 16.3 g/t Au over 15.7 m.
- Drilling confirms continuity of mineralization over a 600-metre strike length.
- Resource update expected following continued drilling efforts in 2022.
- Strategically located near major gold mines, increasing exploration opportunities.
- None.
RENO, Nev., May 3, 2022 /PRNewswire/ - i-80 GOLD CORP. (TSX: IAU) (OTCQX: IAUCF) ("i-80", or the "Company") is pleased to announce results from the final hole drilled in the Phase 1, 2021, surface drill program focused on delineating the high-grade "South Pacific" extension horizon at the Company's Granite Creek Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada.
The South Pacific Zone ("SPZ") is a new zone of high-grade gold mineralization located immediately north of the underground mine workings at Granite Creek (see Figure 1). In 2021, sixteen (16) holes were drilled to test the SPZ (including one hole that was abandoned prior to reaching target depth), successfully defining multiple fault structures that are demonstrating continuity of mineralization over a strike length of approximately 600 metres and a dip length of approximately 250 metres that remains wide open for expansion along strike and at depth. Hole iGS21-18 was drilled in the southern portion of the horizon, closer to the underground workings, and as in several previous holes returned impressive gold grades and widths of mineralization in multiple horizons.
Highlight results from hole iGS21-18 in the South Pacific Zone (and adjacent horizons):
- 16.3 g/t Au over 15.7 m (0.48 oz/ton Au over 51.5 feet)
- 33.7 g/t Au over 3.7 m (0.98 oz/ton Au over 12.0 feet)
The SPZ is the priority target of the ongoing surface drill program at Granite Creek and will be included in a resource update following the 2022 program. SPZ consists of multiple subvertical fault structures located within both the Upper and Lower Comus rock units that appear to trend north to northeast (see Figures 1 and 2). Continued step-out drilling to expand mineralization both along strike and at depth is being completed in 2022. Table 1 provides a complete summary of results from drilling in the SPZ in 2021.
"When combined with the Ogee Zone, that is the focus of underground drilling at Granite Creek, we are extremely excited by the results to-date in the South Pacific Zone that confirm the significant upside opportunity", stated Tyler Hill, Senior Geologist of i-80. "Drilling in 2022 will continue to step-out along strike and at depth to further expand the mineralized envelope, while at the same time, we are extending the decline to expedite development and mine planning of the SPZ."
High-grade mineralization at Granite Creek occurs in a near-identical geological setting as that at the multi‑million‑ounce Turquoise Ridge Mine located immediately to the north (see Figure 3); proximal to a major regional fault (the Getchell or Range Front fault) on the eastern edge of the large Osgood Mountains intrusive complex. The Granite Creek deposit remains open at depth and along strike from the existing underground workings.
