A prefeasibility study (PFS) on a block cave expansion of the Carrapateena copper/gold project, in South Australia, has unlocked the potential of the province, ASX-listed Oz Minerals said on Tuesday.
The PFS is base don the conversion of the lower portion of the current sub-level cave into a series of block caves, which would significantly increase the value of the project, as well as the reserve and mine life of the Carrapateena operation.
