MDN Inc./Isambara Project Update: Substantial Progress Made in the Identification of Gold-Bearing Zones

MONTREAL, QUEBEC--(Marketwire - March 19, 2009) - MDN Inc. ("MDN") (TSX:MDN) is pleased to announce it has resumed of exploration work at its Isambara project (Tanzania) following substantial progress made in the interpretation of the geological model and in the compilation of available data.

The company's observations are as follows:

- The Isambara gold-bearing zones are oriented at 310 degrees and dipping northeast.

- The zones are frequently intersected by mafic dykes, thereby creating pronounced displacements to the left (sinistral).

- There are obvious similarities with the geometry and sinistral displacements found in the gold-bearing structure of the Tuluwaka Gold Mine.

- Higher grade gold mineralization is located mainly below 40 meters in vertical depth, whereas several drill holes bored to date did not test mineralized zones below this depth.

- The gold-bearing zones remain open both laterally and in depth.

The key element in interpreting the geological model has been the identification of sinistral displacements of the gold-bearing zones at each intersection with a mafic dyke. These displacements were identified alongside the numerous dykes in part due to drilling conducted for the 2008 exploration program, which allowed for the interpretation of the geometry, distribution and continuity of high grade gold-bearing structures.

Furthermore, with the drilling data accumulated to date on Isambara, gold-bearing zone appears as a "lead structure" hosting higher grade (more than 10 g/t) gold values with several adjacent intercepts of lower grade structures (0.2 to 1.5 g/t Au) mineralization forming a 10 to 25 meter envelop. The "lead structure" and its envelop could be followed section by section during the 2009 exploration program.

"Now that we understand the displacements at the dykes, which indicates that several separate zones are in fact a continuous zone of mineralization. The geometry of the deposit allows us to say that the gold-bearing zones remain open laterally " stated Marc Boisvert, P.Eng., MDN's Vice President - Exploration. One of the objectives of the 2009 exploration program will thus be to ascertain the continuity in high grades within the same structure, while determining the physical continuity of each zone at each extremity, keeping in mind sinistral displacement.

High grade structures sometimes extend for hundreds of meters in length before being abruptly displaced to the left by one of many mafic dykes. In fact, data on the South Zone indicate that it extends for over 800 meters before its gold content falls completely upon contact with a new dyke.

The next steps of the Isambara exploration program will be to complete a detailed geochemical soil survey, to collect new samples in keeping with sinistral displacements and to complete a compilation / cartography of the anomalies in the identified structures. A drilling program will then commence as rapidly as possible.

Located 28 km north of the Tulawaka Gold Mine, the Isambara project is wholly owned by MDN and covers an area of 40 km2.

MDN Inc. is a mining exploration company with its head office in Montreal, Quebec. Its main exploration activities are conducted in Quebec through wholly and partly owned gold and base metal interests, and in Tanzania, through a majority interest in 35 mineral licenses surrounding Tulawaka, in addition to a 30% interest in the Tulawaka Gold Mine.
