A prefeasibility study (PFS) into the Windarra gold tailings project, in Western Australia, has proven positive, prompting ASX-listed Poseidon Nickel to launch a definitive feasibility study on the project.
The PFS estimated that the Windarra gold tailings could produce some 44 000 oz of gold based on the processing of the North and South tailings dams, using a low-cost hydraulic mining and a new conventional 1.5-million tonne a year cyanidation-leach processing facility.
