OZ Minerals Eyes Up Block Cave Opportunities At Carrapateena Underground Mine



A prefeasibility study on an expansion of OZ Minerals’ Carrapateena copper-gold underground mine, in South Australia, has indicated a block cave conversion in the lower portion of the Carrapateena resource has the potential to almost double average production from 2026.

It is these results, plus the potential Block Cave 1 and Block Cave 2 expansion net present value of circa-A$770 million ($534 million) at final investment decision in 2023, that has seen the company confirm it will progress the plan to feasibility study stage, with the Carrapateena Block Cave Expansion Feasibility Study Stage 1 report expected before the end of 2021.
