| ROBEX/Nampala, Drilling Results Summary of Past Campaigns; Include Gold Values of: 3.45 g/t Over 25 Meters and 1.37 g/t Over 77 Meters Including 4.38 g/t Over 15 Meters |
QUEBEC CITY, QUEBEC--(Marketwire - April 11, 2011) - Robex Resources Inc. (TSX VENTURE:RBX) (FRANKFURT:RB4) announces the conclusion of its reverse circulation (RC) drilling campaign of the Nampala deposit. Results of those campaigns have revealed grades such as 3.45 g/t over 25 meters and 1.47 g/t over 57 meters including 3.28 g/t over 14 meters. Those campaigns, totaling 192 drill holes within the oxidized zone of Lens 100, served to complete the drilling at 25 meters spacing (as recommended by Coffey Mining in the 43-101 Resource Calculation report) as well as to define the north-east extension of the Nampala deposit on the Mininko permit. A revised resource calculation is in progress with the purpose of integrating all the results obtained to date. Robex is confident that it will achieve its objective of 350 000 to 375 000 ounces of gold within the oxidized zone. To date, the Nampala deposit contains a resource of 290,000 oz indicated, 419,000 oz inferred on lens 100 and 86,000 oz inferred on lens 200 and 300, for a total of 795,000 oz.
A core drilling campaign of more than 3 000 meters was initiated on the 29 of March 2011. Results from this campaign will be combined to those from the RC campaign in order to confirm previously obtained results. The results from these drill holes will also serve towards the slope calculation requirements needed to design required the mine's plan, as well as to strive to have the indicated resource migrate to measured and indicated. While the deeper drill holes will serve to increase the inferred resource below the oxidized zone.
The following table summarises the overall drilling results obtained during the Nampala RC campaign(i):

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 has just initiated the required field visits in order to define the application modalities.
Robex is also:
-- The N'Golopene permit, located directly on the extension of the gold
anomaly at the Syama mine (gold producing property owned by Resolute
Mining Ltd., which contains over 6 million ounces of gold and produced
77,926 ounces in 2010);
-- The Diangounte permit, located only a few kilometers from the Sadiola
and Yatela mines (property owned by IAMGOLD and AngloGold Ashanti, which
contains 8.5 million ounces of gold and produced 178,000 ounces in
2010);
-- The Wili-Wili and Wili-Wili West permits, characterised by a large gold-
bearing dispersion 2.8 km by 600 m wide and immediately adjacent to the
Siribaya project owned by IAMGOLD and Merrex;
-- The Sanoula permit, surrounded by Golden Rim permits, with which
discussions are in progress concerning an eventual joint venture;
-- The Kolomba permit, which produced good results in earlier campaigns and
is currently overrun with artisanal gold panners.
In addition, Robex has two RC drilling machines, along with the advantage of an experienced drilling team, which renders the company independent in conducting its own RC drilling campaigns.
