Name of the Project
Grassy Mountain gold project.

Location
Eastern Oregon, in the US.

Project Owner/s
Paramount Gold.

Project Description
A feasibility study has outlined an underground mining operation with exceptional economic viability yielding strong net present value (NPV) and internal rate of return (IRR) results.

The project has measured and indicated resources of 28.03-million grading 1.17 g/t gold and 3.67 g/t silver.

Proven and probable reserves are estimated 1.73-million grading 6.82 g/t gold and 9.94 g/t silver.

Envisaged is an operation with an initial eight-year mine life, producing 362 000 oz of gold and 425 000 oz of silver.

The mine plan has been developed using a drift-and-fill underhand mining method.

Processing from the upper portion of the mine is expected to start concurrently with the completion of the processing plant and infrastructure.

Following ramp up, the mine is expected to produce an average of 1 300 t/d to 1 400 t/d, four days a week, which will provide enough material for the 750 t/d mill and processing plant to operate at full capacity for seven days a week.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value (NPV),  at a 5% discount rate, of $123-million and an internal rate of return (IRR) of 27.9%, which increases significantly to an NPV of $238-million and an IRR of 44.7% at $1900/oz.

Capital Expenditure
The project as initial capital costs of $97.5-million.

Planned Start/End Date
Not stated.

Latest Developments
The Oregon State Technical Review Team’s (TRT’s) water subcommittee has accepted the project’s ground baseline data report (BDR).

Including the groundwater BDR to date, 22 BDRs have been accepted by state regulators. The remaining geochemistry BDR has been filed with the Oregon Department of Geology and Mineral Industries (Dogami) and is expected to be approved later in June.

Dogami is reviewing the consolidated permit application submitted by the company in December 2021, including all document revisions and company responses to comments by the agencies from the first application filed in November 2019.
