MDN Reports Its Financial Results for the Second Quarter of 2012

MONTREAL, QUEBEC--(Marketwire - Aug. 13, 2012) - MDN inc. ("MDN")(TSX:MDN) announces its financial results for the second quarter ended June 30, 2012. The management discussion and analysis and the interim financial report will be available Tuesday August 14, 2012, on the Corporation's website www.mdn-mines.com and on SEDAR (www.sedar.com).

A net loss of $583,820, or $0.006 per share, was incurred for the second quarter compared to a net loss of $154,462, or $0.003 per share for the same period in 2011. MDN revenues are historically attributable to royalties distributed from the Tulawaka gold mine in Tanzania. During the first half of the year, due to capital expenditures of US$9.6 million, a 3% increase for the same period in 2011, and a reduced gold production, MDN royalties distributed for the first half of 2012 totaled $313,144 compared to $1,187,830 for the first half of 2011. As of June 30, 2012, working capital for the Company amounted to $7.73 million.

Tulawaka Mine

Total gold production for the Tulawaka mine was 10,537 ounces during the second quarter compared to 21,517 ounces for the same quarter in 2011. Direct operating costs for the quarter were US$1,305 per ounce sold compared to US$645 for the same quarter in 2011. This cost increase is mainly due to a lower level of production, increased mining activity (related to low grade ore at surface), combined with higher maintenance costs for an aging fleet of mining equipments and a general increase in administration costs.

Capital expenditures during the first half of the year totalled US$9.6 million of which US$5.5 million went towards underground development and exploration drilling of the extensions and US$ 4.1 million of sustaining capital for the mine.

Reserves replacement and extension of the life-of-mine

African Barrick Gold ("ABG") continued its underground exploration program and announced the replacement of reserves mined in the first half of 2012 and also announced the extension of the life-of-mine until 2013. Diamond drilling is continuing in order to verify the depth, plunge and extensions of the mineralised veins between levels 10 and 12, under the current reserves in the East Zone. MDN remain confident of further extending the life-of-mine.

Exploration in Tanzania

Nikonga

During the second quarter, a second drilling program on the Nikonga project commenced June 11, 2012. As of June 30, we had drilled 793 meters of a planned program of 1,850 meters. A total of 4 holes are completed (NKD-03, 04, 05 and 06) and sampling is underway.

The objective of this program is to test drilling extensions of NKD-02 (12.3 g/t Au over 4.2 m and 10.9 g/t Au over 4.9 m) in the "Keseria Main" zone with 7 additional drillings. Two more drillings are planned further north; with the aim of verifying the parallel structure Keseria North, already intersected by drilling NKRC-14 (14.5 g/t Au / 2m). Also an additional drilling will test the soil anomaly located in the northern part of the property, where the soils show the highest values ΓÇïΓÇïon the property.

A ground magnetic survey was completed for a total of 177 km of lines spaced every 100 meters to cover an area of ΓÇïΓÇï16 km2.

Ikungu East

MDN acquired mining properties located to the East of its Ikungu property. The new property covers an area of ΓÇïΓÇï133.33 km² and MDN holds 100% ownership. The mining licences of these properties were granted to MDN by the Ministry of Energy and Minerals of the United Republic of Tanzania.

The geological compilation of available information and the interpretation of the data by MDN geologists suggest that the eastern extension of Ikungu's gold structure on these new mining permits continues. The acquisition of these properties will allow MDN to explore 15 additional kilometers alongside Ikungu's structure. This new property covers a large portion of the territory located between the Ikungu property and the artisanal gold mining site "Magarombe", which is aligned with the colonial mine "Buhemba" in terms of high gold-bearing production. The mine produced 393,000 tonnes of ore at a grade of 12 g/t Au.

A program of mapping and prospecting is underway. In addition, to accelerate exploration work on the main Ikungu property in order to complete a 43-101 resource report, MDN is currently seeking an investment partner.

Crevier project development

Throughout the first half of the year, we continued with the development of the feasibility study for the Crevier project. Expenses for the second quarter totalled $246,725 and efforts were focused on the development of metallurgical processing. In terms of the development of the flotation process, a second metallurgical pilot plant test is planned in the second half of 2012 in order to complete the feasibility study in 2013.

The hydrometallurgy program is progressing as planned and so far, the test results tend to confirm the assumptions used in the preparation of the Preliminary Economic Study for the Crevier project and show that we could have an improvement in the parameters used.
