Name of the Project
McDermitt lithium project.

Location
Malheur County, on the Oregon-Nevada border, in the US.

Project Owner/s
Exploration company Jindalee Resources.

Project Description
A November 2024 prefeasibility study (PFS) confirmed the project’s strong economic returns. The project has a maiden probable ore reserve of 251-million tonnes at1 751 parts per million of lithium, containing 2.34-million tonnes of lithium carbonate equivalent.

The PFS processing schedule supports a 63-year production life; however, the production target and forecast financial information excludes any production beyond 40 years.

The PFS envisions a conventional openpit mining method, with a low strip ratio and no blasting required owing to the soft and friable nature of the ore and waste material.

Production is estimated at 1.8-million tonnes of battery-grade lithium carbonate over the life-of-mine. Average lithium carbonate production over the first ten years of operation is estimated at 47 500 t/y. Over the first 40 years of operation, the project is expected to produce about 44 300 t/y.

The full 63-year PFS processing schedule is based on processing 79% probable ore reserves, 3% indicated resources and 18% inferred resources, with forecast total production of 2.5-million tonnes of lithium carbonate.

Potential Job Creation
The project is expected to create 1 000 jobs during construction and 600 jobs during operation.

Net Present Value/Internal Rate of Return
The PFS estimates an after-tax net present value of $3.23-billion at an 8% discount rate and an internal rate of return of 17.9%, with a payback of five years.

Capital Expenditure
Preproduction capital is estimated at $3.02-billion, including 21% contingency.

Planned Start/End Date
Construction and commissioning are expected to take three years, with prestrip
mining starting in the third year.

Latest Developments
The project has been officially designated as a “transparency project” under the US Fixing America’s Surface Transportation Act (FAST-41) permitting framework.

FAST-41 improves the coordination, predictability and transparency of federal permitting for projects of national strategic importance. Projects designated under FAST-41 are listed on the Federal Permitting Dashboard, ensuring publicly accessible permitting timelines and enhancing interagency cooperation. Transparency projects benefit from increased visibility and coordination between federal and state agencies, which, according to the US Department of the Interior, is intended to promote faster decision-making and remove unnecessary delays.

Key Contracts, Suppliers and Consultants
Fluor (processing studies and capital expenditure); and Cube Consulting (pit designs and mining schedule).
