MDN Inc.: Exploration Update, Ikungu Property, Tanzania

MONTREAL, QUEBEC--(Marketwire - March 5, 2010) - MDN inc. ("MDN") (TSX:MDN) announces that the Ikungu drill program was restarted with two drill rigs on January 28, 2010. The objective of this program is to systematically drill the main gold-bearing reef along a 2.5 km strike length.

In January 2009, the MDN geological team obtained encouraging grab sample results from artisan mining sites in the west sector such as 56.80 g/t gold and 70.10 g/t gold. The average gold content of 11 grab samples from the east sector was 12.04 g/t. Drilling by previous owners in the early 2000s yielded good drill intersections in the east sector, including IKD-06 (11.50 g/t Au over 1.0 m), SIK8 (11.50 g/t Au over 5.9 m) and SIK1 (24.50 g/t Au over 3.9 m).

From October to December 3, 2009, MDN completed 10 diamond drill holes (IKD-17 to IKD-26) totalling 2,024 meters out of the total planned program of 4,500 meters. The program was suspended for the holiday season, and resumed on January 28, 2010. Since this time, five holes (IKD-27 to IKD-31) have been completed. The entire program is expected to be finished by the end of March with drill hole IKD-37. Assays results have been received for holes IKD-17 to IKD-30.

Ten holes were drilled along the main reef and another five holes (IKD-19 to IKD-23) tested other areas on the property. The ten holes along the reef were drilled to verify continuity, and to-date results confirm that the mineralization is hosted by metasedimentary rock for at least 2.5 km along strike. The metasedimentary rock hosts continuous gold-bearing sulphides with high-grade mineral lenses associated with highly silicified zones along the main reef. Assays results received so far indicate the possible existence of two high-grade mineralized lenses. Holes IKD-18, IKD-25 and previous owner drill hole IKD-04 outline a central high-grade lens from 2435 E to 2770 E. Holes IKD-26, IKD-28 and previous owner holes IKD-06 and SIK1 outlined an eastern high-grade lens from 3190 E to 3790 E along the main reef.

The second part of the drill program that began in January is focusing on delineating the high-grade lenses along the favourable horizon.

Results from the Ikungu main reef are as follows with grey cells indicating previous owner drill results. Note that holes IKD- 19 to IKD-23 were drilled on other targets and did not yield significant gold values.

The Ikungu gold-bearing structure in Tanzania brings an excellent discovery potential to MDN. We are encouraged by the ongoing drill program on this promising gold-bearing reef. We expect to continue with a follow-up phase during 2010, once the current program will end", said Serge Bureau, President and CEO of MDN.

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 20% control samples.
