Robex Resources Inc./Update on Metallurgical Testwork of Nampala Ores: High Recoveries and Low Reagent Consumption Confirmed

QUEBEC CITY, QUEBEC--(Marketwire - Feb. 16, 2011) - Robex Resources Inc. (TSX VENTURE:RBX)(FRANKFURT:RB4) is pleased to announce that additional metallurgical test work in progress at SGS Lakefield confirmed the initial high recovery and low reagent consumption achieved in 2010 on the original samples. 

The cyanidation tests on four composite samples were done at a pulp density of 40% solids at PH of 10.5-11.0 and a cyanide concentration of 1.0g/L NaCN with a retention time of 36 to 48 hours. The ore composites were ground to P80 minus 160 micron and averaged between 1.22 and 1.55 gpt gold.

Recoveries between 87.5% and 90.3% were achieved after 36 hours only with a reagent consumption of 0.01 Kgm/t of Sodium cyanide and 1.1 to 1.3 Kgm/t of CaO. Additional test work will now concentrate on the optimization of grind versus recovery. A finer grind in the P80 minus 50-75 micron range is expected to improve recoveries further with an expectation of 92 % or better. 

Results from the next batch of test work at Lakefield SGS will be used in the Feasibility Study which was initiated a few months past.

Robex's President and CEO, Mr. André Gagné, declares: We are very pleased that the latest results confirmed the initial testwork and assays. These findings meet our objectives of low costs while minimizing impacts on the environment."

Robex seizes this opportunity to recall that Bumigeme Inc., a Canadian company with a vast experience in the development of dressing procedures and mineral plants operation, has been awarded the contract for performing the Nampala project feasibility study whose purpose is to define the application modalities of an open-pit mining operation using a 5000 tons a day cyanide processing plant.
