A scoping study by ASX-listed Oz Minerals has shown that converting the lower portion of the planned Carrapateena sub-level cave to a block cave, could deliver significant value for the company.
Oz on Wednesday told shareholders that by converting to a block cave from 2026, the company could more than double the mine throughput rate at Carrapateena from 4.25-million tonnes to between 10-million and 12-million tonnes a year, while also increasing the life-of-mine average copper production to between 105 000 t/y and 125 000 t/y from 2026.
