UPDATE - PRIMARY ORE PROCESSING UPDATE – ROCKLANDS MINING ROCKLANDS TRIAL ORE PROCESSING AT ERNEST HENRY MINE COPPER MINE 29.5% COPPER & 6.7 GRAMS PER TONNE GOLD CONCENTRATE ACHIEVED
Preliminary results from the mineral processing testwork at the Glencore-owned Ernest Henry Copper Mine processing plant were outstanding and surpassed expectations, considering only thirty hours of throughput was possible for the Rocklands ore. Approximately 22,000 tonnes of sulphide primary ore at 1.36% Cu + .49g/t Au was mined and transported, for the trial, the first and only sulphide ore mined at Rocklands to date. The near surface sulphide ore for the testwork was excavated from the South-East end of the Las Minerale Pit, immediately adjacent to the Native Copper zone. The ore was processed in a thirty hour window over two days, to test the ore for handling, crushing, milling, flotation and filtration characteristics through a full size production mineral processing facility.


CuDeco metallurgists conclude the result demonstrates that the Rocklands primary ore is amenable to high recovery and as having good metallurgical characteristics for processing through flotation treatment. The testwork revealed no issues with processing the ore and the results were described as exceptionally pleasing, given that normally a much longer period of time is required to settle the circuit down before controlled adjustments of reagents within the rougher and the cleaner flotation circuits can be made. Recoveries were increasing over the period of the trial without optimum conditions being reached. Gold in concentrate was 6.7 grams per tonne average. The Ernest Henry Plant will not be treating any Native Copper ores from Rocklands. The native copper is to be processed entirely at the Rocklands Copper Project processing plant.

MINING UPDATE  Mining is continuing at the rate of approximately 30,000 tonnes per day; 
Stockpiles of ore are approximately +1 million tonnes @ 3% CuEq Oxide/Native Copper; 
Mining is concentrating on the LM 1 Pit for the high grade + 11% Cu Native Copper zone being mined and stockpiled for processing and sale as DSO; 
To date only 22,000 tonnes of sulphide primary ore mined (used for the trial processing at EHM) now completed; 
4 million tonnes easily accessible of sulphide primary ore if favourable long term agreements for sale are reached with third parties (or until prior to commissioning of the process plant);  Main Crushing Circuit now crushing and screening the native copper stockplies;

 Ore Sorter frames complete awaiting ore sorter delivery early December;  Native Copper shipment arrived in Shanghai for smelting testwork- underway, and  The sulphide ore will remain untouched in the NW and SE on either side of the Native Copper 600m zone within the Las Minerale 1.6 km orebody until required for processing
