Lachlan Star is Pleased to Announce Final ROM Trial Results Received, Recovery of 45% Adopted for Planning

PERTH, WESTERN AUSTRALIA--(Marketwire - Dec. 7, 2012) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR RELEASE, PUBLICATION, DISTRIBUTION OR DISSEMINATION DIRECTLY, OR INDIRECTLY, IN WHOLE OR IN PART, IN OR INTO THE UNITED STATES

Gold miner, Lachlan Star Limited ("Lachlan" or the "Company) (TSX:LSA)(ASX:LSA) is pleased to announce that based on the final ROM trial results it will be adopting a recovery of 45% for the ROM material. This is in line with previous guidance.

The second 2 Stage Crush trial is ongoing and will be finalised in early 2013.

The recoveries achieved for ROM, 2 Stage Crushing and 3 Stage Crushing process routes are shown in Figure 1, with an accuracy of +-2%. As expected, leach kinetics are in general faster with the higher level of crushing. The final 3 Stage Crush recovery is based on the use of a dynamic pad, whilst the ROM and 2 Stage crushing trials have used a static pad.

Results have been based on 7,500 tonne trial parcels of lower grade (0.25 g/t Au to 0.30 g/t Au) mineralisation from the Toro and Tres Perlas deposits and are considered indicative of what will be achieved in the operations. Cyanide consumption for the ROM material is lower than the 3 Stage Crushed material at 0.45 kg/t compared to 0.60kg/t respectively.
