MONTREAL, QUEBEC–(Marketwired – April 26, 2013) – April 26, 2013 – MDN Inc. (“MDN”) (TSX:MDN) reports that it has received a request from Metalinvest Capital Corporation (“Metalinvest”) for an extension to May 13, 2013, for the transfer to MDN’s account of the funds required to start the initial exploration program on the Ikungu property in Tanzania. MDN has granted Metalinvest the extension. On February 25, 2013, MDN announced the signature of an agreement with Metalinvest providing for MDN to transfer a 55% undivided interest in its interest in the prospecting licences of the Ikungu property to Metalinvest. To maintain its 55% undivided interest in MDN’s interest in the Ikungu property, Metalinvest must incur US $14 million in exploration expenditures over a four-year period, including US $3 million by December 31, 2013. Metalinvest may accelerate exploration spending at its discretion. MDN will manage the exploration work.

Pursuant to the agreement, the management committee was set up in March, consisting of two representatives each of MDN and Metalinvest. A US $3 million work program was presented to and approved by the committee. To maintain its option, 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. It was unable to do so, and asked for an extension until May 13.

Ikungu: one of the most advanced gold projects in Tanzania

Ikungu is an advanced exploration project with a large gold-bearing zone and 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.
