A prefeasibility study (PFS) into the Warrawoona gold project, in the Pilbara region of Western Australia, has estimated that some 580 490 oz could be recovered over an initial six year mine life.
ASX-listed Calidus Resource on Wednesday told shareholders that Warrawoona could be developed at a capital cost of A$95-million, with the PFS estimating a pre-tax net present value of A$151-million, based on a A$1 800/oz gold price.
