Name of the Project
Granite Creek gold project.

Location
Humboldt County, in Nevada, in the US.

Project Owner/s
i-80 Gold Corp.

Project Description
A preliminary economic assessment (PEA) has confirmed the substantial economic opportunity that can be realised through the development of openpit and underground mines on the Granite Creek property.

For the openpit, the study envisions the construction of a heap-leach facility and a carbon-in-leach plant on site. 

For the fully permitted underground operation, the trucking of mined material is proposed to be processed at an off-site, third-party processing facility. 

The openpit project has measured and indicated resources of 28.31-million tonnes process material at 1.42 parts per million (ppm) and inferred mineral resources of 1.53-million tonnes process material at 1.26 ppm. The underground project has measured and indicated resources of 1.01-billion tonnes process material grading 10.4 g/t, and inferred resources of 741-million tonnes grading 13.41 g/t gold.

Based on the current resource estimates for the property, the study envisions a mine life of nine years during which about 1.25-million ounces of gold will be produced.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at a 5% discount rate, of $244.9-million and an internal rate of return of 34.2%.

Capital Expenditure
$69.9-million.

Planned Start/End Date
Not stated.

Latest Developments
A major surface and underground drill programme of about 20 000 m is under way and the company is completing additional underground development and starting test mining in advance of making a production decision for the underground mine.

i-80 Gold has initiated preliminary permitting studies required for openpit mining. Expansion drilling is stepping out at depth and along strike where the deposit remains open; results from this programme will be released throughout the balance of 2021 and well into 2022, with the target of completing a feasibility study in the future.
