MDN Announces Tulawaka Year-End 2012 Operational Results

MDN Announces Tulawaka Year-End 2012 Operational Results 
MONTREAL, QUEBEC -- (Marketwire) -- 02/13/13 -- MDN Inc. ("MDN")
(TSX:MDN) notifies its shareholders that African Barrick Gold plc
(ABG), the project operator of the Tulawaka gold mine in Tanzania in
which MDN has a 30% participating interest, announced fourth quarter
and annual operational results.  
ABG have successfully extended the life of this operation
consistently in the last three years; however as part of ABG
Operational Review, ABG have taken the decision not to further extend
the mine life beyond the middle of 2013. ABG are currently starting
to implement a closure plan for the operation. Therefore in 2013, ABG
will focus on the progression of closure planning. Options for
divestment will also be considered.  
"In spite of the closing of Tulawaka Mine, MDN with $3.5 million
working capital, plus its valuable Crevier Nb - Ta deposit and
quality projects in Tanzania, MDN have a good base to continue to
persist and to develop the value of the company in the following
years compared to several peers in the current condition market" said
Marc Boisvert President & CEO of MDN. 
Tulawaka is becoming a historical successful story for a junior
mining company as MDN. MDN succeeded to finance the Tulawaka
construction during an era of low gold price and kept going at the
rapid building pace by a major gold producer to succeed the opening
in March 2005. In less than 3 years, MDN succeeded to reduce its debt
obligation and started to accumulate profit from the production at
Tulawaka mine. Funds permitted MDN to increase it land package in
Tanzania and to develop quality exploration projects. Today, Ikungu
is an advance drill project with a mineral gold zone. It is one of
the most advance project in Tanzania with blue sky potential not
under control of a major company. At Ikungu East, MDN acquired the
control over 15 km strike length of a volcanic belt not observed
until this day. At Nikonga, MDN did a drill discovery with NKD-02
drill hole intersecting 12.3 g/t Au over 4.26 m (PR March 27, 2012)
and finally the Isambara project with the potential for bulk mining
mineralization style.  
In parallel, it permitted a strategic investment in 2009 where MDN
acquired control in a Niobium - tantalum deposit located in Quebec
Canada which is taking value with the feasibility in progress and
increasing price and demand of Tantalum metal. This strategic
investment was implemented as an alternative and anticipation of the
Tulawaka mine aging. Crevier deposit is expected to bring future
revenue to MDN. Progress are made to become one of the most secure
and reliable supply of Tantalum in a near future.  
Operating performance (reflected as 100 %)  
The total mine gold production for the year was 44,338 ounces
compared to the 84,101 ounces achieved in 2011. The decreased gold
production level resulted from lower mined grade from underground
stopes and the application of batch milling in order to drive plant
efficiencies. Gold ounces sold were broadly in line with production.  
Cash costs for the year were US$1,269 per ounce sold compared to
US$727 in the prior year. This cost increase was mainly due to the
lower production base and the impact of lower capitalised mining.
These were slightly offset by lower sales related costs due to lower
sales ounces. 
Cash costs per tonne milled increased to US$219 in 2012 from US$146
in 2011, primarily as a result of a lower mill throughput due to the
batch milling campaign.  
Capital expenditure for the year of US$24.6 million was 22% lower
than the prior year of US$31.7 million. Key capital expenditure
included capitalised exploration drilling and underground development
costs (US$10.2 million) as we tested the potential to extend the mine
life and infrastructure investments into the tailings storage
facility, security and accommodation (US$4.2 million) which will form
part of the closure plan. Included in capital expenditure is a
non-cash reclamation adjustment which amounted to US$1.3 million. 
Impairment charges  
During Q4 2012, impairment charges of US$44.5 million were recorded
against Tulawaka by ABG. This impairment for ABG will not affect
MDN's financial reporting. The agreement between MDN and ABG is
related only to the liquidity available at end of the periods.
