Underground ore reserves extend Prominent Hill life to 2029

An 18% increase in the underground ore reserve at Prominent Hill could extend the mine’s life to 2029, copper/gold miner Oz Minerals reported on Tuesday. The increase in underground ore reserves to 39-million tonnes at 1.7% copper equivalent has enabled an expected underground production rate of 3.5-million tonnes to 4-million tonnes a year from 2019 to continue through to 2029, according to the ‘Prominent Hill mineral resource and ore reserve estimate at 30 June 2017’ report.
