NEWS RELEASE TRANSMITTED BY CCNMatthews FOR: NORTHERN MINING EXPLORATIONS LTD. TSX SYMBOL: MDN September 29, 2005 MDN NORTHERN MINING: New Gold Discovery in The Tulawaka Area, Tanzania MONTREAL, QUEBEC--(CCNMatthews - Sept. 29, 2005) - MDN NORTHERN MINING (MINIERES DU NORD) (TSX:MDN) is pleased to announce a new gold discovery from its recently completed first phase drilling campaign in the Tulawaka area, Tanzania. MDN NORTHERN MINING has been actively exploring for gold in the area immediately surrounding the Tulawaka project, where it has a 30% interest. The Tulawaka gold mine started commercial production in March this year and had produced 62,400 ounces of gold by the end of August. MDN NORTHERN MINING completed a drilling campaign testing three targets. Drilling was done with rotary air blast (RAB) and reverse circulation (RC) techniques for a total of 5,092 m. This press release reports the results from a target located in a Prospecting License optioned from Lakota Resources, some 25 km of the Tulawaka mine process plant. The target covers an area 1.3 km long and 0.6 km wide and has been initially tested initially by four drill fences comprising 34 holes for a total of 2,266 m. Holes were sited "heel-to-toe" on the fences to give complete overlap, drilled at an angle of 60 degrees and to an average depth of 70 m. Drill fences are spaced between 100-400 m from each other. Because of the drilling techniques used, it is not possible to accurately determine the true width and orientation of the mineralized intersections. The best drill intersections from this target are summarized below: /T/ Hole Interval Length Gold Gold check number (m) (m) (g/t) (g/t) ---------------------------------------------------------- ISRC 21 40 - 43 3 8.63 6.95 ISRAB 07 10 - 12 2 1.16 2.01 ISRAB 09 13 - 16 3 0.52 1.58 ISRAB 16 31 - 34 3 1.46 1.07 ISRAB 21 01 - 06 5 14.93 13.22 40 - 70 30 6.37 5.86 including 45 - 53 8 14.54 13.49 /T/ Samples from this drilling program were prepared and analyzed entirely by Humac Laboratories in Tanzania. The anomalous results were subsequently independently checked by the ALS Chemex laboratory in South Africa. The drilling program was carried out under the direction of Geologist Brian Lloyd, supervised by Carlos Bertoni, P.Geo., a Qualified Person under NI 43-101. Results from the drilling of the remaining targets will be released shortly, as they become available and have been verified. A follow-up drilling program is being prepared to test not only the gold mineralization being discovered, but also to probe two additional targets in other Prospecting Licenses. A map showing the Company's current tenement interests in the Tulawaka area is available on its web site (www.xnord.com). The Company initially defined a number of exploration targets by studying all the available information within a radius of 50 km from the Tulawaka mine. These targets are being systematically tested using proven exploration techniques. Soil geochemistry is used to determine the location of gold mineralization in the lateritic profile, from which anomalies are defined. Follow-up work with induced polarization/resistivity geophysical surveys identifies geological structures and assists in the design of drilling programs. Targets defined were previously completely unknown and this exploration represents pioneering work for the area. Carlos Bertoni, CEO of MDN NORTHERN MINING, stated: "In 2002 we decided to launch our own exploration effort in the area surrounding the Tulawaka project, confident that the local geological environment holds the potential to host additional gold mineralization. Our objective has been to find new gold deposits in the vicinity of the Tulawaka processing facility, and thus produce gold from mines in which we will have a higher participation. These recent drilling results are very encouraging and demonstrate that we are on the right track. We are now busy preparing for our new drilling campaigns and look forward to delivering more good news in the near future. We are building a success story in East Africa, based on a strong mining asset, effective exploration and professionalism in all aspects of our operations". MDN NORTHERN MINING is a Montreal-based Canadian exploration company that holds a 30% interest in the Tulawaka gold project and a majority interest in 25 adjacent mineral licenses in Tanzania, a majority interest in three licenses in Eritrea, and other gold and base metal exploration interests in Quebec, Canada. - 30 - FOR FURTHER INFORMATION PLEASE CONTACT: MDN NORTHERN MINING Carlos H.
