Name of the Project
NiWest nickel/cobalt project.
Location
Adjacent to Glencore’s Murrin Murrin operation, in the north-eastern goldfields of Western Australia.
Project Owner/s
Alliance Nickel, formerly GME Resources.
Project Description
An updated feasibility study has confirmed the robustness of a long-life operation producing high-purity nickel and cobalt sulphate products, to be delivered to lithium-ion battery raw material markets.
The mine and process schedule remain unchanged for the 2018 prefeasibility study (PFS) that proposes conventional openpit mining at a low strip ratio of 2:1.
Envisaged is a 27-year mining operation with a nameplate ore throughput of 2.4-million tonnes a year, resulting in total production of 456 000 t nickel (in nickel sulphate) and 31 400 t cobalt (in cobalt sulphate). Projected steady-state nickel and cobalt recoveries are estimated at 79% and 85% respectively.
Average production over the first 15 years is expected to be 19 200 t/y nickel and 1 400 t/y cobalt.
The processing route selected is heap leaching followed by neutralisation, impurity removal, direct solvent extraction and crystallisation to produce nickel and cobalt sulphate products.
Forecast operating and capital costs have been re-estimated through further prospective supplier interaction and general inflationary scaling.

Net Present Value/Internal Rate of Return
The updated PFS presents three financial projections.
In Case 1, the project has a net present value, at an 8% discount rate, of A$1.88-billion and an internal rate of return of 21.6%, with a payback of 4.4 years.
In Case 2, the project has a net present value, at an 8% discount rate, of A$2.6-billion and an internal rate of return of 25.9%, with a payback of 3.7 years.
In Case 3, the project has a net present value, at an 8% discount rate, of A$3.31-billion and an internal rate of return of 29.7%, with a payback of 3.3 years.
Capital Expenditure
Preproduction capital expenditure has increased from A$966-million in the 2018 PFS to A$1.26-billion in the updated PFS.
Start/End Date
Construction is expected to take 24 months from the final investment decision, with the forecast heap pad and plant ramp-up phase taking about 20 months.
Latest Developments
Alliance Nickel has received a letter of support from Export Finance Australia (EFA) to provide potential financing for the project.
Subject to EFA board approval, the letter of support could be converted into a binding agreement following due diligence, sufficient lender support and other customary financing terms.
The next step in securing project finance would be the completion of the definitive feasibility study for NiWest, as well as further due diligence work.
Alliance earlier this year signed a binding offtake agreement with automotive maker Stellantis over the NiWest project, covering up to 170 000 t of nickel sulphate and 12 000 t of cobalt sulphate over an initial five-year offtake term, amounting to 40% of the future yearly forecast from NiWest.
