MONTREAL, QUEBEC–(Marketwire – Sept. 13, 2010) – MDN Inc. (“MDN”) (TSX:MDN) is pleased to report the assay results for the first two holes (IKD-38 and IKD-39) of the drilling program currently underway on the Ikungu property. The program consists of a total of 5,000 metres of drilling in 13 holes. The primary goal is to demonstrate that higher grade mineralized zones identified by MDN near surface during earlier drilling programs are continuous to a vertical depth of 300 metres.

• The IKD-39 intercept lies 250 metres vertically below the Hole IKD-35 intersection grading 2.79 g/t Au over 6.51 m;
• The IKD-39 intercept lies 100 m east and 205 m vertically below the eastern down-dip extension of Hole IKD-36 intercept of 8.02 g/t Au over 2.41 m;
• Holes IKD-39 (19.26 g/t Au over 1.53 m), IKD-32 (8.02 g/t Au over 2.41 m), IKD 35 (2.79 g/t Au over 6.51 m) and IKD 18 (5.79 g/t Au over 2.76 m) indicate the potential of a mineralized lens in the central portion of the gold-bearing horizon traced over 2.5 km;
• The intersection of 8.46 g/t Au over 1.37 m in Hole IKD-39 is a parallel zone in the hangingwall of the main zone. This intersection shows the presence of mineralization parallel to the main mineralization, increasing the potential for discovery of other mineralized zones nearby.

“These early drill results are very encouraging. Hole IKD 39 shows the presence of high grades and vertical continuity at over 300 metres. Furthermore, in compiling all the results to date, we recognize a mineralized zone similar to those discovered at the Tulawaka mine, our joint-venture property with African Barrick Gold,” said Marc Boisvert, Ing., Vice President Exploration for MDN.

Holes IKD-40 and 41 have been completed and are now being assayed, and holes IKD-42 and IKD-43 are presently being drilled.

The samples were analysed by fire assay at the SGS Laboratory of Mwanza, Tanzania, which is certified according to international standards. A rigorous quality analysis verification program implemented by MDN included 10% control samples. The technical and scientific information contained in this press release has been reviewed by Marc Boisvert, engineering geologist and Vice President, Exploration, who acts as a qualified person in accordance with National Instrument 43-101.
