Gold development company Solidus Resources.
Project Description
The project will be Nevada’s next long-life heap-leach gold mine comprising 3.8-million ounces of proven and probable mineral reserves at an average gold grade of 0.016 oz/t.
The project will have a life-of-mine (LoM) of 21 years, including two years of construction, 11 years of mining, three additional years of ore processing, and five years of reclamation and closure activities.
The feasibility study proposes a simple heap-leach operation with a large openpit mine design and straightforward layout. The project will average 303 000 oz/y of gold over its LoM, with 348 000 oz/y gold over the first five years.
Potential Job Creation
The project will hire about 130 contractors during the two-year construction and and 250 full-time staff for operations.
Net Present Value/Internal Rate of Return
The feasibility study has estimated an after-tax net present value, at a 5% discount rate, of $1.5-billion and an after-tax internal rate of return of 36%, with a payback of less than two years.
Capital Expenditure
$822.7-million.
