MDN Inc.: Tulawaka 2012 Third Quarter Results/Focus on Mine Life Extension

MONTREAL, QUEBEC--(Marketwire - Oct. 26, 2012) - MDN Inc. ("MDN") (MDN.TO) reports to its shareholders that African Barrick Gold plc (ABG), the operator at the Tulawaka gold mine in Tanzania, in which MDN has a 30% participating interest, announced its third quarter and nine months operational results.

Highlights

At Tulawaka, there was an increased focus on underground development work aimed at extending the mine life. As a result, there was a 30% decline in ore tonnes mined compared to Q3 2011. Together, with the lack of surface stockpiles, this led to continued batch processing of the underground material blended with mineralised waste.

Operating performance

The focus during the quarter at Tulawaka was on increasing underground development rates and as a result, lower ore tonnes were mined and a higher proportion of ore tonnes were sourced from lower grade development stopes.

The batch milling campaign continued in the quarter resulting in a 37% decrease in throughput compared to Q3 2011. In order to maximise efficiencies in the process plant, ore tonnes mined were blended with mineral waste for processing, which led to a 16% reduction in head grade against the prior year and together with the lower throughput led to total gold production for the quarter of 10,773 ounces compared to the 20,160 ounces produced in Q3 2011. Gold ounces sold were 10% higher than production.

Cash costs for the quarter were US$1,309 per ounce sold compared to US$749 for third quarter of 2011. This was mainly due to costs being spread over the lower production base and increased consumables usage driven by drilling supplies, explosives and ground support material used in the underground development.

Capital expenditure for the quarter totalled US$7.6 million compared to US$8.1 million for the same period in 2011. Key capital expenditure items included:
