Any engineers/geos with technical knowledge able to advise the likelihood and costs of mining nickel oxides near Kambalda would be much appreciated.

Hey Mav,

Dilute acid heap leach at atmospheric pressures should be feasible at minimal capital expense and low-OPEX, blast-free mining.

Assuming 70-80% recoveries of say 300Kt @ 3% Nickel Oxide material could yield 6-7Kt of nickel.

Worth pursuing as resource target with inexpensive infill aircore drilling.

Thanks @pangea!

The report above states that discussions have been initiated with parties capable of treating non-sulphide ore...from your experience has oxidised nickel ore been successfully treated in the past around Kambalda or anywhere else in Aus?
