MDN Provides an Update on Ikungu and Assesses the Mineral Potential of the 3-km Long Gold-Bearing Structure

MONTREAL, QUEBEC--(Marketwire - April 12, 2011) -

Editor's note: A map for this release is available on Marketwire's website.

MDN Inc. ("MDN") (TSX:MDN) is pleased to provide a progress report on drilling at its gold Ikungu property in Tanzania, as well as an assessment of the mineral potential of this 3-km long gold-bearing structure.

Drilling to test gold soil anomalies in the extensions at both ends of the mineralized zone began on January 20, 2011. Because of logistical difficulties encountered by the contractor, only one drill, an RC drill, was mobilized instead of two. The second drill, a diamond drill, arrived on site at the end of March, and is now drilling the western sector, an unexplored 1-km-wide area between sections IKD-33 and IKBH-42.

In the western area, drilling on sections 970E and 1195E is complete, and assay results show that Section 970E cuts through the mineralized structure, with an intersection of 2.87 g/t Au over 2 metres in Hole IKBH-48 (true thickness unknown). Combined with the earlier results of Hole IKBH-42 on Section 1195E, this means that the mineralized zone has now been traced by drilling over an additional kilometre to the west (see attached longitudinal).

To the east, drilling intersected rocks that are favourable to mineralization 770 metres farther east than the last intersection in IKD-43 (1.21 g/t Au over 3.73 m, true thickness). Assays are pending.

Preliminary Assessment of Gold Potential

The 2010 results have identified a mineralized zone more than 3 km long, including a 2-km section with enough information to assess the mineralized material. Based on 42 holes and surface mapping, MDN has outlined and modeled a continuous, conceptual mineralized zone. The intersections indicate that the zone is continuous and has good grade and volume potential. Thirty of the 42 holes, or 71%, intersected more than 2 g/t Au over a 2 m horizontal width (1.88 m true thickness). A preliminary assessment also allows optimal planning of future drilling aimed at outlining a gold resource on the 2-km section.

The volume of the model was quantified using two block methods: cross-section and longitudinal section. The conceptual scenarios indicate that, at a cut-off grade of 3 g/t Au, the mineralized zone would contain 1.9 to 3.8 million tonnes grading between 6.07 and 8.92 g/t Au, equivalent to 550,000 to 757,000 ounces of gold.

"We are extremely pleased with the preliminary assessment on this gold property, which was discovered by MDN's exploration team and points to a promising future for us in Tanzania," stated Serge Bureau, President and Chief Executive Officer of MDN.

The mineralized zone is made up of intervals averaging 2 to 15 m horizontal width (1.88 m to 14.1 m true thickness) with grades of 1.21 to 24.5 g/t Au. Drilling has outlined a zone 2.0-km long, extending to a vertical depth of 325 m. The geological model developed by MDN shows a zone striking 110°and dipping southward at a constant 70°.

It should be noted that volume and grade are hypothetical and estimates are conceptual. Furthermore, the exploration done to date is insufficient to delineate mineral resources, and it is uncertain whether more detailed exploration would establish the presence of resources.

Based on the consistency of intersections in the mineralized zone and the results obtained one kilometre farther west, MDN believes that the gold mineralization extends laterally and at depth outside the assessment area, in the direction of the strike and dip.

Samples were analysed by fire assay at the SGS Laboratory of Mwanza, Tanzania, which is certified according to international standards. A stringent analysis quality 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 is a qualified person under National Instrument 43-101.
