MDN Reports a 29% Increase in Gold Production at Tulawaka for the Quarter and Extension of Mine Life
MONTREAL, QUEBEC–(Marketwire – Oct. 20, 2011) – MDN Inc. (“MDN”) (TSX: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 third quarter and nine months operational results ended September 30, 2011. Highlights include:
- The Tulawaka mine continues to deliver increased grades from underground higher grade areas
- A detailed update of the resource and mine life at Tulawaka is planned for the end of the year
Gold production at Tulawaka (100%) for the quarter was 20,160 ounces, a 29% increase over the prior year period which totalled 15,646 ounces. Year to date production for 2011 totalled 61,291 ounces, 42% higher than the prior year. The increase in production was a direct result of mining higher grade underground stopes supported by improved mine equipment availability. This translated into a head grade of 6.8 g/t, compared to 4.1 g/t in the prior year period, and improved recoveries. Lower throughput was the result of the increased proportion of feed coming from higher grade ore which has a higher grind index than the surface stockpiles.
Cash costs for the quarter were $749 per ounce sold, the same as the prior year period. Year to date cash costs were $707 per ounce, 4% higher than the prior year. The increase in underlying costs has been offset by an increase in ounces produced for the quarter resulting in flat costs on a per ounce basis.
Cash costs per tonne milled for Q3 2011 increased to $162 per tonne milled compared to $92 per tonne milled in prior year period due to the 24% decrease in tonnes milled together with higher operating costs. Year to date cash costs per tonne milled increased from $82 in 2010 to $140 in 2011.
Capital expenditure for the quarter of $8.1 million was 52% higher than prior year period of $5.3 million. The main areas of capital expenditure were $1.7 million for security and $1.4 million for underground development. Non-cash reclamation adjustments amounted to $4.3 million. Year to date capital expenditure totalled $17.4 million, including underground drilling work for $2.1 million, representing a year-on-year increase of 62%.

EXPLORATION AND DEVELOPMENT UPDATE
At Tulawaka East Zone Underground, exploration drilling continued to extend the known high-grade mineralised shoots below current reserves. We have now identified sufficient mineralisation in order to extend the mine life to the end of 2012 and are assessing the potential to further extend the mine life beyond this.
Diamond drilling continues to test depth, plunge and strike extensions to the mineralised lodes below current reserves throughout the Tulawaka mine. A total of 46 diamond core holes for 4,070 metres were drilled between Level 8 and Level 15 throughout the underground area, but primarily focused on the western areas of the underground during the quarter. Underground drilling for the remainder of the year and into 2012 will begin to target high grade extensions below the East Pit in Zones 550 and 800. Drilling to date shows the mineralised quartz veins extend at least down to Level 12, and has intersected visible gold within quartz veining in several drill holes, such as TUGD00359 – 0.5m @ 10.90g/t from 41.5m, TUGD00356 – 2.5m @ 8.56g/t from 105.5m.

Mojamoja – West Zone “Gap” – Surface drilling
A total of 22 RC holes for 2,389 metres were drilled as part of an infill programme, between the West Zone and Mojamoja prospects, in the “Gap” area. The Mojamoja and West Zone prospects lie approximately 4km northwest of the Tulawaka plant, and ABG is looking at the potential to delineate further open pit resources to be trucked to this plant. The current infill programme is aimed at delineating additional resources between the two previously drilled areas, and could potentially increase the overall open pit resources. All assays were pending at the end of the quarter.
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 are done by ABG Tulawaka Mine Geologists.
