Vanadium junior miner Critical Minerals Group (CMG) has released a mineral resource estimate update for its flagship Lindfield project near Julia Creek which diversifies its offer.
The 713Mt figure is a 96 per cent increase in size.
Company managing director Scott Winter says they’ve added molybdenum to the resource estimate on top of vanadium and associated high purity alumina (HPA).
The indicated and inferred resources estimate of 713Mt at 0.32 per cent vanadium pentoxide, 3.4 per cent aluminium oxide and 130g/t molybdenum includes more than 68 per cent in the indicated category.
And 72 per cent of the resource (518Mt) is located within 20m of the surface.
The resource increase stemmed from a drilling program completed in September 2023, providing material for pilot scale and further metallurgical test work.
CMG said the upgraded resources incorporated the upper horizon (TLBA) at the deposit as a result of its outstanding beneficiation performance.
Mr Winter says the metallurgical test work highlights the superior performance of the TLBA (upper horizon) mineralisation in upgrading its concentration through the flotation.
“The test work and modelling also highlighted the build-up of molybdenum in the circuit to economic levels,” he says.
“With these inclusions, the overall planning, development and economics will be worked on further in the next phase of the feasibility studies.
“The improvements to be added will include lower waste removal volumes, lower strip ratio, increased mineralised material, increased mine life potential and the potential for an additional revenue source through the production of molybdenum.”
Sedgman will complete a definitive feasibility study for the Lindfield project.
