A prefeasibility study (PFS) into the Bald Hill lithium mine, in Western Australia, has estimated that project construction would require a capital investment of A$42.2-million to support production of 155 000 t/y of spodumene concentrate over an initial mine life of 3.6 years.
ASX-listed Tawana Resources said on Tuesday that the project was also expected to deliver 260 000 lb/y of tantalum pentoxide from a flotation circuit, based on a maiden lithium ore reserve of 4.3-million tonnes, at 1.18% lithium oxide and 208 parts per million tantalum pentoxide.
