The definitive feasibility study (DFS) proposes an average mine production rate of 780 000 t/y, peaking at 840 000 t/y over the life-of-mine (LoM), which is based on an ore reserve of 11.48-million tonnes, mined over 14.6 years.
The DFS envisages two integrated operations, a mining and processing operation, to produce a lithium concentrate (spodumene), and a hydrometallurgical plant to convert the spodumene into battery-grade lithium hydroxide monohydrate (LHM).
The hydrometallurgical plant is expected to produce 8 800 t/y of LHM, with a total production of about 129 000 t of LHM over the LoM.
Total spodumene concentrate production is estimated at 90 000 t, coarse feldspar at 1.95-million tonnes, fine feldspar at 587 000 t, total coarse quartz at one-million tonnes and total fine quartz at 164 000 t.

Capital Expenditure
Estimated capital expenditure is estimated at $873-million.
Planned Start/End Date

Latest Developments
ECM Lithium, a wholly owned subsidiary of Critical Metals, has received confirmation from the Carinthian state government that an environmental-impact assessment (EIA) is not required.
This exemption from the EIA process will fast-track the Wolfsberg project’s approval, potentially positioning it as a key player in the European supply chain for critical minerals.
The regulatory decision stems from new provisions for underground mining projects that stipulate if the surface area is expected to cover less than 10 ha, an EIA is not necessary under Austrian law.
