Insights

The reported drill results from i-80 Gold Corp's Granite Creek Property present significant findings for stakeholders, indicating substantial high-grade gold mineralization. The continuity and grade of the gold deposits, particularly with assays such as 28.1 g/t Au over 4.4 m, are indicative of a potentially economically viable deposit. These results may lead to an increase in the company's resource estimates, positively influencing its market valuation.

From a mining perspective, the true widths of up to 15 meters and grades frequently exceeding 10 g/t Au are noteworthy. In the context of gold mining, grades above 5 g/t Au are often considered high-grade, thus these results suggest the potential for a profitable mining operation, provided other factors such as depth, accessibility and ore recovery rates are favorable. The mention of the deposit's geological similarity to the nearby Turquoise Ridge Mine, a significant gold producer, further underscores the prospectivity of the SPZ.

Investors will likely focus on the implications these drilling results have for i-80 Gold Corp's financials and growth prospects. The announcement of advancing an initial development plan for the SPZ in the first half of 2024 could be a catalyst for future revenue growth. Furthermore, the proximity to Nevada Gold Mines' Turquoise Ridge Mine suggests potential for strategic partnerships or acquisitions, which could impact the company's stock performance.

It is also important to consider the costs associated with advancing the project to the production stage, which will require significant capital expenditure. However, given the high-grade nature of the deposit, the long-term return on investment could be substantial, enhancing the company's appeal to growth-oriented investors.

The SPZ's classification as a Carlin-type deposit is significant, as these are known for their large endowment of gold and typically low extraction costs due to the disseminated nature of the gold. The geological setting is conducive to large-scale gold systems, which is supported by the reported drilling results. The sub-vertical orientation and location at the contact of limestone units are characteristic of Carlin-type deposits and suggest potential for further discoveries at depth and along strike.

The QAQC procedures mentioned, including the use of independent and accredited labs, as well as the insertion of standards and blanks, provide confidence in the reported assay results. Such rigorous quality control is crucial in accurately defining the extent and grade of mineralization for resource estimation and future feasibility studies.

Highlights 28.1 g/t Au over 4.4 m, 10.6 g/t Au over 9.4 m & 13.6 g/t Au over 5.2 m

RENO, Nev., Feb. 7, 2024 /PRNewswire/ - i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) ("i-80", or the "Company") is pleased to announce the results from the successful 2023 surface drilling program designed to define and expand high-grade gold mineralization in the lower South Pacific Zone at the Company's Granite Creek Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada.

The South Pacific Zone ("SPZ") is expected to become the primary horizon for mining once initial development has been extended to provide access.  In the second half of 2023, drilling was completed from underground in the upper portion of the SPZ where initial stoping is expected and where recently released results include 31.1 g/t Au over 21.9 m, 28.7 g/t over 16.5 m and 37.7 g/t Au over 7.6 m. Thirteen holes were drilled from surface (twelve reached target) to better define an area where initial drilling suggested the potential for increased grades and mining widths – these results are summarized in this release.

Highlight results from 2023 surface drilling in the South Pacific Zone (core width)

  • 26.1 g/t Au over 5.7 m (0.76 oz/ton Au over 18.7 feet) in hole iGS23-01*
  • 10.6 g/t Au over 9.4 m (0.31 oz/ton Au over 30.9 feet) in hole iGS23-02A
  • 25.6 g/t Au over 5.5 m (0.75 oz/ton Au over 18.2 feet) in hole iGS23-03*
  • 28.1 g/t Au over 4.4 m (0.82 oz/ton Au over 14.5 feet) in hole iGS23-04
  • 15.5 g/t Au over 19.7 m (0.45 oz/ton Au over 64.7 feet) in hole iGS23-05*
  • 8.3 g/t Au over 8.7 m (0.24 oz/ton Au over 28.2 feet) in hole iGS23-08
  • 27.0 g/t Au over 2.1 m (0.79 oz/ton Au over 6.9 feet) in hole iGS23-09
  • 13.6 g/t Au over 5.2 m (0.40 oz/ton Au over 17.2 feet) in hole iGS23-10A

* Previously released

The South Pacific Zone is a sub-vertical, Carlin-type, mineralized horizon that occurs predominately at the faulted contact of the Upper and Lower Comus (limestone) rock units. Following successful 2021/2022 drilling campaigns that identified a continuous zone of high-grade mineralization over a significant strike length in the SPZ target, the 2023 surface and underground drilling programs targeted the definition of two areas within this horizon to assess continuity of mineralization in preparation for initial mine planning (see Figure 1). Both programs have been extremely successful, demonstrating true widths of up to 15 metres and results frequently in excess of 10 g/t Au.

With improved definition, an initial SPZ development plan is being advanced in the first half of 2024.  Upon completion of a successful test mining program, additional underground drilling will be completed for the release of an updated resource estimate and Feasibility Study. The SPZ remains open for expansion at depth and along strike to the north towards Nevada Gold Mines' Turquoise Ridge Mine (see Figure 2). Table 1 provides a summary of results from surface definition drilling in the SPZ in 2023.

"The continuity of high-grade mineralization in the South Pacific Zone is outstanding.", stated Ewan Downie, Chief Executive Officer of i-80. "The results from our 2023 definition programs demonstrate the potential for the SPZ to be a significant deposit located on strike from one of North America's largest gold mining operations.  Mineralization remains open at depth and along strike to the north with the average intercept grade in the northern extension definition program of approximately 15 g/t gold with true widths ranging up to 15 metres."

The SPZ is a priority for development and the Company is extending the decline to depth in order to provide access to the SPZ for it the become part of the Granite Creek mine plan in H1-2024. High-grade mineralization at Granite Creek occurs in a similar geological setting to the multi-million-ounce Turquoise Ridge Mine located immediately north (see Figure 2); 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.

QAQC Procedures

All samples were submitted to ALS Minerals (ALS) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through ALS are run through standard prep methods and analysed using Au-AA23 (ALS) (Au; 30g fire assay) and ME-ICP41 (36 element suite; 0.5g Aqua Regia/ICP-AES). ALS also undertakes 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.
