CuDeco Limited announced an updated Ore Reserves estimate for its Rocklands Copper Mine, as flagged in its earlier announcement. Highlights: Total Rocklands Ore Reserves estimated at 11.6 million tonnes (Mt) (0.87% copper (Cu) and 0.21 gold (Au) grams/tonne) as at 31 December 2017; Reserves update excludes potential sales of cobalt and magnetite - future recovery of cobalt remains an option if shown as commercially viable; Pit optimisation process to be commissioned for next Reserve Update for fiscal 2018; and Operational improvements continue, with planning underway for further reserves growth through orebody discoveries amid rising copper and cobalt prices.
