Name of the Project
Mt Mulgine tungsten project.

Location
Murchison region of Western Australia.

Project Owner/s
Critical minerals developer Tungsten Mining.

Project Description
A prefeasibility study (PFS) has confirmed the technical and financial viability of a six-million-tonne-a-year mining and processing operation at Mt Mulgine.

The project has maiden mineral ore reserves of 140-million tonnes grading 0.10% tungsten, 288 parts per million molybdenum, 0.12 g/t gold, 5.9 g/t silver and 0.03% copper. The ore reserve estimate and mine plan are based entirely on indicated mineral resources.

The PFS envisages average production of about 460 000 t/y of tungsten in concentrate over the life-of-mine, with production of by-product concentrates of molybdenum and copper/gold/silver, with contained metal of about 1 070 t/y of molybdenum, 1 265 t/y of copper, 9 400 oz/y of gold and 525 000 oz/y of silver.

The project will be mined using conventional bulk drill-and-blast and load-and-haul methods.

The PFS estimates a long-life operation, with a life-of-mine of 24.5 years.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 5% discount rate, of A$422-million and an internal rate of return of 10.83%.

Capital Expenditure
The project has a total capital cost of A$669-million.

Planned Start/End Date
The execution strategy to deliver the project to operational status has yet to be formalised.

Ore production is expected 13 to 15 months after the start of site establishment.

Latest Developments
Tungsten Mining has started a scoping study to evaluate a staged development approach, combining a potential startup oxide gold operation with longer-term tungsten and molybdenum production.

The ten-week study will assess capital and operating costs, mine design, infrastructure, tailings management and approvals, with a focus on optimising the sequencing between gold production and full-scale tungsten operations. Results are expected in the next quarter.

The staged pathway is aimed at generating early cash flow from gold, reducing project risk and establishing a clear route to unlocking Mt Mulgine’s tungsten resource.

The study is contingent on the forthcoming mineral resource estimate for the Camp prospect and an exploration target for gold at Mulgine Trench, both expected to be released this quarter.

“This scoping study is a pivotal step in our strategy for Mt Mulgine, as it will define how we can generate early cash flow from gold while building towards large-scale tungsten production. By sequencing development in this way, we aim to reduce project risk, maximise infrastructure synergies and establish a clear pathway from startup to a long-life operation,” Tungsten Mining chairperson Gary Lyons has said.
