MDN Terminates Its Agreement With Metalinvest for the Ikungu Project

MONTREAL, QUÉBEC--(Marketwired - May 15, 2013) - MDN Inc. ("MDN") (TSX:MDN)reports that it has notified Metalinvest Capital Corporation ("Metalinvest") that it has terminated the agreement signed on February 25, 2013, between MDN and Metalinvest for the financing of an exploration program on the Ikungu project in Tanzania.

Following the creation in March of a management committee consisting of two representatives each of MDN and Metalinvest, a US $3 million work program was presented to the committee and approved. Metalinvest was to deposit the funds required to cover the expenditures for the first half of 2013 within days of the approval of the exploration program to maintain its option, but was unable to do so, despite being granted an extension until May 13. MDN has notified Metalinvest of the termination of the agreement.

MDN has already initiated contact with other groups who may be interested in accelerating exploration of the Ikungu project. Ikungu has excellent growth potential. It is one of the most advanced projects in Tanzania and one of the few not owned by a major gold producer. The property covers 17.9 km2 and lies 17 km southwest of Musoma and 135 km northeast of Mwanza, Tanzania's second largest city.

It should be recalled that the 53 holes drilled in earlier exploration programs on Ikungu identified a mineralized zone that extends more than two kilometres along strike and 300 metres vertically. Drilling has delineated four higher-grade gold zones formed around the intersections in holes IKD-45 (8.6 g/t Au over 14.78 m) on Section 2230mE, IKD-48 (3.11 g/t Au over 9.50 m) on Section 2830mE, IKD-51 (3.39 g/t Au over 7.05 m) on Section 3190mE and IKD-36 (13.22 g/t Au over 4.62m) on Section 3610mE.
