Name of the Project
Finniss lithium project.
Location
South of Darwin port, in the Northern Territory, Australia.
Project Owner/s
Lithium developer Core Lithium.
Project Description
The updated definitive feasibility study for Stage 1 has confirmed that Core Lithium is well positioned to be the next lithium producer in Australia. The project has been recognised by the Australian and Northern Territory governments as being significant to the economy, and holds major project status.
Finniss has total ore reserves estimated at 7.4-million tonnes grading 1.3% lithium oxide, supporting an eight-year mine life. This is based on using openpit mining methods at the Grants and Hang Gong deposits, and underground mining methods at the Grants, BP33 and Carlton deposits.
Stage 1 of the project will involve mining the high-grade spodumene pegmatite deposit from multiple openpit and underground sources; the transfer of the spodumene pegmatite ore to a run-of-mine pad adjacent to the Grants openpit; water-based, dense-medium separation to produce a high-quality spodumene (lithium) concentrate product; and the transport of the lithium concentrate product to the Port of Darwin by sealed public road for overseas export.
The mine will support yearly lithium production of 175 000 t/y from a one-million-tonne-a-year plant.
Potential Job Creation
Core will employ a workforce of about 300 personnel during the life of the mine. Currently, more than 80% of the contractors and direct employees live in Darwin and work at Finniss.
The BP33 project will employ 60 people during construction, and about 150 people during operations.
Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate, of A$221-million and an internal rate of return of 53%, with a two-year payback.
Capital Expenditure
Not stated.
Planned Start/End Date
The project is on target to export direct shipping ore (DSO) lithium by the end of 2022, following the first sale of spodumene DSO product announced on October 3.
Latest Developments
Early works and the updated feasibility study at BP33 are progressing well and the project is on track for final investment decision in the March quarter of 2024.
