MDN Inc.: Tulawaka Mine Produces 20,493 Ounces of Gold During the First Quarter of 2009

MONTREAL, QUEBEC, Apr 29 (MARKET WIRE) --
MDN Inc. ("MDN") (TSX: MDN) is pleased to announce that the Tulawaka Gold
Mine in Tanzania produced 20,493 ounces of gold during the first quarter
ended March 31, 2009. Tulawaka gold production now amounts to 674,860
ounces since the beginning of operations in March 2005.

For the first quarter, 20,881 ounces of gold were sold into the spot
market at an average price of US$906 for total sales of US$18.9M. Since
the beginning of operations in March 2005, a total of 666,959 ounces of
gold was sold.

For the first quarter, a total of 34,911 tonnes were mined from the
underground mine at an average mine grade of 11.27 g/t gold whereas the
plant facilities processed 101,974 tonnes of ore at an average grade of
6.7 g/t gold and at a gold recovery rate of 93.3%. The difference in
tonnage comes from the stockpile at the plant.

"The fact that the underground operations at Tulawaka are still in
development and therefore limit our access to known mineral zones
explains the use of low-grade ore stockpiled near the mill and the low
tonnage mined underground", said Paul-A. Girard, President and CEO of MDN.

Total cash costs averaged US$418 to produce an ounce of gold during the
first quarter of 2009. The ROM (Run of Mine) stockpiles at quarter end
were 402,122 tonnes at an average grade of 2.72 g/t gold, representing
approximately 12 months ore supply for the process plant, assuming the
current throughput of 32,000 tonnes processed per month due to the
hardness of the rock on the stockpiles.

Paul-A. Girard, President and CEO of MDN stated: "The production level
and mining operations of the underground mine for the quarter are as
planned. Indeed, approximately 35% of the tonnes processed come from the
underground mine which produces a better grade than the stockpiles used
to fulfill the production capacity of the mill. The tonnes processed from
the underground mine should improve quantitatively in the upcoming months
and given the challenge related to the beginning of the underground
operations, we are pleased with the results and remain optimistic towards
the mining plan aimed at increasing the reserves and resources, and
expanding the mine life."

The Tulawaka Gold Mine is owned and operated by Barrick Gold Corporation
("Barrick"), through its Tanzanian subsidiary Pangea Minerals Ltd.
Pursuant to a Joint Venture Agreement Barrick has 70% participating
interest and MDN has 30% participating interest in the Tulawaka Gold
Mine. The information disclosed on the Tulawaka Gold Mine is based on
