MDN Inc.: Tulawaka First Quarter Results

MONTREAL, QUEBEC--(Marketwire - April 19, 2012) - MDN Inc. (TSX:MDN) ("MDN") reports to its shareholders that African Barrick Gold plc (ABG), the project operator at the Tulawaka gold mine in Tanzania, in which MDN has a 30% participating interest, announced first quarter operational results.

Operating performance

Total gold production at Tulawaka for the quarter was 15,963 ounces compared to the 19,616 ounces produced in Q1 2011. Higher grade ore from the underground mining area was blended with lower grade supplemental ore from the West pit extension, resulting in a slight decrease in head grade. Gold ounces sold were broadly in line with production and down 8% on Q1 2011 reflecting the lower production.

Cash costs for the quarter were US$902 per ounce sold compared to US$738 in the prior year. This cost increase was mainly due to the increase in open pit mining activity which resulted in increased headcount, maintenance and contracted services as well as year-on-year inflationary increases. These were partially offset by increased capitalized mine development costs due to the higher underground mining cost base.

Cash costs per tonne milled increased to US$158 in the quarter from US$123 in Q1 2011, primarily as a result of the cost increases detailed above and lower throughput.

Having extended the mine life twice in 2011, ABG is also continuing the exploration drilling programs and is aiming to be in a position later in the year to make a commitment to further mine life extensions. As a result of the mine life extensions and lack of availability of surface material from Q2 2012, the process plant will begin to operate under a batch processing method. The reduction in throughput will see reduced production during the second quarter before an expected increase in the grade profile in H2 2012. Work will also continue through 2012 to construct a second underground portal to enable the operator to increase mining rates from the underground.

Capital expenditure for the quarter totaled US$5.1 million compared to US$3.9 million for the previous year. Key capital expenditure items included:

1. Capitalized development: capitalized underground development (US$2.4 million); and capitalized exploration drilling (US$0.8 million).
2. Expansion capital: expenditure incurred on the extension of the mine life (US$1.7 million)

Exploration and Development Update

Tulawaka East Zone Underground Extensions

The current program is targeting high grade mineralized shoots within Zones 500-850 between Levels 11 and 15, below the current reserves. The drill results to date indicate that the mineralization is exhibiting similar characteristics as in the upper levels of the mine.

Selected assay results for Tulawaka underground drilling during the quarter included:

- TUGD00427: 1.1m @ 9.80g/t Au from 15m (including 0.5m @ 15.6g/t Au from 15.6m),

- TUGD00430: 2.2m @ 13.7g/t Au from 32.6m (including 0.56m @ 37.9g/t Au from 32.6m)

- TUGD00437: 1.58m @ 120g/t from 15.52m and 2m @ 34.8g/t from 21m

- TUGD00443: 0.85m @ 680g/t from 15.75m

These grades zones were intersected at the hanging wall between Levels 11 and 12 (550 zone) which ties in well with the expected high grades at the eastern portion of the deposit. The underground drill program is expected to continue throughout 2012 targeting the eastern areas of the underground which to date have had limited testing due to lack of drill drive access.

The samples were analyzed by fire assay at the Tulawaka Mine Laboratory and SGS Laboratory of Mwanza, Tanzania, which both are certified according to international standards. Supervision of the drill program and of the quality analysis verification program is done by ABG Tulawaka Mine Geologists. Marc Boisvert, geological engineer, Vice President, Exploration, and a qualified person under National Instrument 43-101 has reviewed the technical and scientific information in this news release.

The Tulawaka project is a contractual joint-venture between MDN (30% participating interest) and Pangea Goldfields Inc. (70% participating interest), a wholly owned indirect subsidiary of African Barrick Gold plc and project operator and owner through its subsidiary Pangea Minerals Ltd. The information disclosed on the Tulawaka Gold Mine is based on information provided by the Operator.
