Name of the Project
Black Pine oxide gold project.

Location
Cassia and Oneida counties, in Idaho, in the US.

Project Owner/s
Mineral properties developer Liberty Gold, through its wholly owned subsidiary Pilot Gold.

Project Description
The project consists of three large deposits and several smaller deposits that are planned to be developed using conventional openpit mining methods over a 17-year life-of-mine (LoM).

Gold will be recovered using run-of-mine (no crushing, screening or agglomeration) heap leaching, with material delivered by mine haul truck stacking onto a single heap-leach pad at the eastern extent of the project. The pad is designed in four phases to contain up to 315-million dry tonnes of leachable material, with operational segregation of the oxide ore types in isolated cells on the leach pad to prevent co-mingling. Ore feed to the leach pad is planned at 18.3-million tonnes a year over the LoM, with average yearly gold production over the LoM estimated at 135 000 oz. Leached gold will be recovered from the solution using a three-train, activated carbon adsorption circuit.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
At a gold price of $2 000 (base case) the project has a pretax net present value, at a 5% discount rate, of $656-million and an internal rate of return if 34%, with an after-tax back of 3.3 years.

Capital Expenditure
Initial capital expenditure is estimated at $326.6-million.

Planned Start/End Date
Not stated.

Latest Developments
In February 2025, Liberty Gold formally submitted the draft Black Pine mine plan of operations to the United States Forest Service (USFS), the Bureau of Land Management (BLM), the Idaho Department of Environmental Quality (IDEQ) and the Idaho Department of Lands (IDL).

It also reported the successful execution of an interagency memorandum of understanding among Liberty Gold, USFS, BLM, the Idaho Governor’s Office of Energy and Mineral Resources, the IDEQ and the IDL to facilitate coordination of the entire mine permitting process for Black Pine. The draft submission of the mine plan of operations is the precursor leading to initiation of the federal permitting process under the National Environmental Protection Act, which will include the completion of an environmental-impact statement.
