QUEBEC, QUEBEC--(Marketwire - May 26, 2011) - Ressources Robex Inc. (TSX VENTURE:RBX)(FRANKFURT:RB4) announces the preliminary results of its diamond drilling campaign, the purpose of which was to complement the RC surveys previously carried out in order to confirm the grades and increase the deposit's resource. Overall, these surveys depict grades of 1% to 20% higher than those obtained previously. The diamond drilling results obtained to date show an increase, including 97 meters at 1.20 g/t compared with RC drilling of 97 meters at 1.08 g/t between 11 and 107 meters (Mn2011DD003 Vs Mn2004ac521). "These are very good results and there's a good correlation of values considering the survey type and especially the precise level of the sections that were sampled", explains André Gagné, Robex's president and chief executive officer.

The campaign initially anticipated approximately 2,000 meters of diamond drilling, however in the wake of the 1.5 million financing that it recently received (see press release dated May 3, 2001), Robex decided to increase the drillings to 5,000 meters. The latter should serve to increase the deposit's inferred resource, as estimated in the Coffey Mining's report #43-101, as well as meeting the expectations of the financial institutions with which Robex has had discussions concerning the financing of its potential mining infrastructures. To date, 4,200 meters of the anticipated 5,000 meters have been drilled. The results obtained during this campaign will be added to those obtained during previous campaigns and will be included in the new resource calculation. It should be noted that a total of 57,561 meters have been drilled at Nampala so far.

Recalling 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 5,000 tons a day cyanide processing plant. The metallurgical tests, recently conducted on the ore, showed high recoveries and low reagent consumption (see press release of February 16, 2011). The engineering firm Met-Chem has been hired to develop the mine plan for this Feasibility study, as announced in the March 2nd, 2011 press release.
