MDN Stakes 98 km2 of Strategic Ground Southeast of Crevier

Identifies a carbonatite-type magnetic signature similar to Niobec

MONTREAL, QUEBEC–(Marketwire – June 13, 2011) –

Editors Note: There is a map associated with this press release.

MDN Inc. (“MDN”) (TSX:MDN) is pleased to report that it has acquired 175 claims covering 98 km2 southeast of the Crevier niobium-tantalum project. This new acquisition means that MDN now controls the ground covering a magnetic geophysical response similar to the one associated with the Niobec niobium mine. The magnetic signature lies 23 km southeast of the Crevier deposit and 130 km northwest of the Niobec mine and the property has been namedSamaqua.

“We have several good reasons to enlarge the footprint of the Crevier project,” said Serge Bureau. “We are in the advanced feasibility study stage, and we recognize that the magnetic signature to the southeast of the project could correspond to another carbonatite-type mineralization with a rare-earth core. Furthermore, it is related to the Crevier deposit via a lineament corresponding to the southeast extension of the Crevier dike. This would mean timely growth for our project given the development of new modern applications for strategic metals.”

MDN staked this strategic position following its analysis of geophysical mapping of the airborne magnetic map published by the Canadian government and the compilation of previous work in the area.

A magnetic signature similar to the Niobec magnetic response has been identified, with a halo of high magnetic intensity surrounding a low-intensity core. In the case of Niobec, the core corresponds to a niobium carbonatite with a rare-earth centre.

The circular anomaly lies at the southeast end of a lineament visible on the geophysical maps. The lineament coincides with the porphyry syenite dike hosting the Crevier deposit and could be the southeast extension of the dyke, in which case the two systems would be related.

The new claims also lie within part of a structural corridor that includes the Saint-Honoré (Niobec) and Crevier carbonatites in the Grenville Province and the Lac Shortt and Montviel carbonatites in the Abitibi.

Historical prospecting work located pegmatitic syenite outcrops within the magnetic halo, which is highly indicative of the presence of an alkaline intrusive favourable to metals like those at Crevier (niobium-tantalum) and /or Niobec (niobium and rare earths).

Reconnaissance work will be carried out on the property during the year to confirm the presence of a carbonatite and its metal content. This work will also enable the Company to verify whether the Crevier mineralized dyke and this circular anomaly are interrelated, as suggested by the presence of the lineament.
