MDN Inc./Isambara Project: New Gold-Bearing Targets Identified in the Southern Area

MONTREAL, QUEBEC--(Marketwire - May 28, 2009) - MDN Inc. ("MDN") (TSX:MDN) has announced that an MMI (Mobil Metal Ion) soil sampling program, successfully conducted in April 2009 on the Isambara project, confirms the geological model previously advanced (see March 19, 2009 press release) with respect to the geometry of the gold-bearing structures, the apparent left-hand displacement of each of the structures, and the presence of numerous parallel gold-bearing structures.

The Southern Area can now be described as a series of parallel gold-bearing structures extending over a strike length of 1.3 km and having significant lateral extensions. To date, these numerous structures have only been partially drill tested.

The circumstances leading to a systematic drilling approach are the following:

- the high gold-bearing values obtained in the soil sampling coincide with the surface projected mineralization transected by the drilling;

- the north-west orientation of the gold-bearing structures is confirmed;

- the eastern and western sides of the Southern Area form part of the same gold-bearing horizon, but are displaced by north-east oriented faults or dykes;

- several extensions of the gold-bearing structures have apparently undergone little or no drill testing;

- the strike length of the Southern Area has been extended from 800 meters to 1.3 kilometers;

- several of the gold-bearing structures appear in a parallel formation;

- a new structure has been discovered at the north end of the Southern Area, where two drill tests previously yielded values of 10.51 g/t of gold over 2 meters (RC233) and 9.45 g/t of gold over 1 meter (RC234).

With these new encouraging data, a drill program will be undertaken during the dry season at the beginning of July in the Southern Area, while two other MMI soil sampling programs will be conducted in the Central and Northern Areas with a view to defining additional drilling targets.

The Isambara Project is characterized by a soil anomaly with a strike length of 5 kilometers divided into three areas (South, Central and North). To date, the main focus has been on the Southern Area in terms of drilling and analysis due to the ease of conducting all the preliminary work for the next drilling.

At the heart of the Southern Area are two structures which have been shown to contain the highest gold-bearing values, although they have barely been tested below a vertical depth of 40 meters. In fact, based on all the drilling data obtained to date for the Isambara Project, the highest gold-bearing values actually appear to be located below the vertical depth of 40 meters.

In the MMI survey, 528 soil samples were obtained, including 26 blank samples to check field and laboratory procedures. Samples were taken every 25 meters along 12 lines spaced 100 to 800 meters apart across the gold-bearing structures of the Southern Area. The samples were prepared in the SGS laboratories in Mwanza, Tanzania, and shipped to the SGS Laboratory in Toronto, Canada, for analysis of the gold and 45 other elements using the MMI procedure.

Located 28 kilometers north of the Tulawaka gold mine, the Isambara Project is wholly owned by MDN and covers a surface area of 40 km2.

MDN is a mining exploration company with its head office located in Montreal, Quebec, Canada. Its main exploration activities are carried out in Quebec and Tanzania. In Quebec, MDN wholly or partially owns a number of gold and base metal exploration interests. In Tanzania, in addition to a 30% equity interest in the Tulawaka Gold Mine, MDN owns a majority interest in 35 mineral licenses in the vicinity of Tulawaka.
