A prefeasibility study (PFS) into the Hayes Creek zinc-gold-silver project, in the Northern Territory, has found that the project would require a capital investment of A$58-million to construct a 450 000 t/y sulphide flotation process plant and associated infrastructure.
ASX-listed PNX Metals said on Wednesday that the project is expected to deliver annual concentrates of 18 300 t of zinc, 14 700 oz of gold and 1.4-million ounces of silver, generating net smelter revenues of A$628-million over a six-and-a-half year mine life.
