MDN Announces Tulawaka Year-End 2010 Operational Results

MONTREAL, QUEBEC--(Marketwire - Feb. 16, 2011) - MDN Inc. (TSX:MDN) - 

Editor's note: A map for this release is available on Marketwire's website. 

MDN Inc. ("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 twelve months operational results.

Operational Highlights

• The focus for the Tulawaka mine has successfully shifted from closure to mine life extension
• The mine's program has continued to outperform the original feasibility study for the underground operations, with an initial extension of its life-of-mine for the full year 2011 and into the second quarter of 2012
• Exploration drilling program will continue at the site with the aim of further increasing the life of mine. If successful, we anticipate this will be based solely on the underground operation through the addition of a second portal. An update on this will be provided later in the year.
• Towards the end of the year, Basie Maree was appointed General Manager of Tulawaka. Basie brings substantial experience of the industry, including a number of years with Anglo American, and will lead Tulawaka forward into a new stage of its development.
• Capital investment projects include additional underground mining equipment for the mine and continued security investment.

Operating performance (reflected as 100%)

Tulawaka has successfully outperformed its original feasibility for the underground operation in terms of reserve additions and ounce production. Throughout the year a key focus of the mine's management has been on exploration and definition drilling to extend the mine life beyond 2011. We are pleased to announce an initial extension of the life-of-mine to the second quarter of 2012 and will continue to focus on further extensions in 2011.

The mine's gold production for the year was 60,134 ounces compared to the 94,180 ounces achieved in 2009. This lower gold-production level resulted from mining lower-grade ore from the underground operations and processing lower-grade material from the stockpiles than in 2009.

Gold ounces sold amounted to 63,909 for the year, 6% higher than production and down 32% compared to 2009, reflecting the decline in production.

Cash costs for the year were US$709 per ounce sold compared to US$413 in the prior year. This cost increase was mainly due to the lower production base and increased mining costs compared with 2009. The increased mining costs were driven by higher fuel, labour and maintenance costs.

Cash costs per tonne milled increased to US$93 in 2010 (US$87 in 2009) primarily as a result of the higher cost of underground mining.

Capital expenditure for the year totalled US$15.5 million compared to US$7.9 million for the previous year. Notable investments included additional mining equipment (US$4.4 million), increased exploration development (US$2.8 million) and the support of mine-life extension.

Exploration and evaluation costs of US$3.6 million were incurred in 2010 to advance the exploration at greenfields projects, namely to test satellite open pit opportunities.

Serge Bureau, President and CEO of MDN commented: "We are supportive of the investment incurred at Tulawaka and are pleased about the initial extension of the life of mine. We look forward to a continuation of the underground exploration program to expand the resource base".

Exploration Review

Tulawaka East Zone Underground Extension

Throughout the year, the focus of the near-mine expansion programmes at Tulawaka was on the East Zone Underground Extensions. The objective of the drilling here is to identify and delineate additional high-grade gold reserves and resources below the current East Zone underground infrastructure, with the primary purpose of extending the life of the Tulawaka mine.

The exploration drilling continued to extend the known high-grade mineralised shoots below the Level 7 resource that had previously been defined, indicating potential to extend the mine life further. Overall, the drilling programmes indicate that existing mineralised zones continue to at least 150 metres below the floor of Tulawaka's now completed open pit. The drill programmes will continue throughout 2011, which will aim to extend known high-grade zones for a further 100-200 metres below currently defined depths. In this way, possible significant expansion of the current resource base will be assessed to add further reserves and extend the mine life through an exclusively underground operation.

African Barrick Gold also published the new Tulawaka Mine Gold Reserves and Resources. During 2010, 72% of the proven and probable reserve was replaced, from 134,000 to 96,000 ounces. The exploration program allowed for a 180% mineral resource increase, from 46,000 to 129,000 ounces, giving further potential life of mine increase. The Reserves and Resources (stated at 100%) are as follows:

	2010			2009
	Tonnes	Grade Au	Ounces	Tonnes	Grade Au	Ounces
	(000's)	(g/t)	(000's)	(000's)	(g/t)	(000's)
Proven and probable	457	6.53	96	526	7.91	134
Minerals Resources	740	5.405	129	249	5.79	46
Inferred	134	4.98	21	0.9	17.84	0.4
