MDN starts drilling its Nikonga gold discovery

– MDN Inc. ("MDN") is pleased to report that today marked the start of a drilling program at its wholly-owned Nikonga property in Tanzania. The goal of the program is to test the strike and depth extensions of the gold-bearing intersections returned earlier in the year by holes NKD-02 and NKRC-14. The following results were reported in news releases dated March 1 and 27, 2012:



NKD-02: intersected 4.39 g/t Au over 26.0 metres, including intervals of 12.3 g/t Au over 4.2 metres and 10.9 g/t Au over 4.9 metres.



NKRC-14: intersected 14.5 g/t Au over 2.0 metres

The current diamond drilling program consists of 8 to 10 holes for a total of 1,300 metres. The results of drilling done earlier this year revealed two subparallel structures with high- grade gold, associated with a gold soil anomaly nearly two kilometres long. The drill results showed three styles of mineralization:

Quartz veinlets a clayey sediment,



Massive quartz-tourmaline veins, and



Quartz tourmaline veinlets in a quartz-feldspar porphyry intrusive.

"The presence of several styles of mineralization, the high grades, the consistency of the assays and the setting are all indications of a potentially significant gold-bearing system. Furthermore, the geological setting has similar features to the great mines of the Timmins camp, like Hollinger and Dome," said Marc Boisvert, MDN’s Vice President of Exploration.

Ikungu property. The Ikungu mineralized zone has been outlined over a strike length of more than two kilometres and to a depth of 300 metres, making it without doubt one of the largest mineralized zones in Tanzania at an advanced stage of drilling. MDN is currently seeking a strategic partner to accelerate the Ikungu project’s development.

The samples were analysed by fire assay at the SGS Laboratory of Mwanza, Tanzania, which is certified according to international standards. A stringent assay quality verification program implemented by MDN included 10% control samples. The technical and scientific information in this press release has been reviewed by Marc Boisvert, engineering geologist and MDN’s Vice President, Exploration, who is a qualified person as defined by National Instrument 43-101.
