Northern Abitibi Provides 2010 Exploration Summary for Viking

CALGARY, ALBERTA--(Marketwire - Dec. 2, 2010) - Northern Abitibi Mining Corp. (TSX VENTURE:NAI) ("Northern Abitibi") is pleased to provide a summary of exploration results from its 2010 exploration program at the Viking gold project, along with an update and timeline for the resource estimate study that is currently underway.

2010 Viking Exploration Summary

During 2010 a total of 9,735 metres of core drilling in 58 holes was completed, 13 new trenches were excavated, and 985 surface samples and 243 soil samples were collected. A substantial surface mapping and prospecting effort was undertaken over the entire property and a high resolution light detection and ranging (LiDAR) and ortho imagery survey was conducted. This substantial exploration program has resulted in a much better understanding of the geology and structural controls on mineralization at Viking which will greatly aid exploration and continuing resource expansion as the project moves forward. Highlights include the delineation of a gold zone along the Thor Trend measuring 600 metres long by 30 to 60 metres wide and extending to 200 metres depth (open at depth), as well as the discovery of four new exploration targets on the property that have good potential to host additional gold resources.

The Thor Trend gold mineralization is characterized by large gold bearing envelopes surrounding narrower high grade vein hosted shoots. The high grade shoots plunge to the south and all of the shoots identified to date remain open for expansion at depth. The 2010 drill program encountered wider zones of gold mineralization than have previously been encountered on the property as well as multiple gold-bearing horizons. These features as well as the near surface location of mineralization make it a favorable target for potential open pit exploitation. Drill results from the 2010 exploration program have confirmed the continuity of the bulk tonnage zones, with intervals such as 80.9 metres grading 0.8 grams per tonne (g/t) gold in hole 51 and 32 metres grading 1.8 g/t gold in hole 60, and also discovered several new high grade shoots including 0.5 metres grading 124.8 g/t gold in hole 58 and 8.5 metres grading 6.4 g/t gold in hole 60. 

Preliminary metallurgical test work was completed on a composite sample of mineralized drill core from the Thor Trend. The results show excellent metallurgical recoveries with 95 to 97% gold recovery by cyanide leaching or combined gravity separation and cyanide leaching. Preliminary tests show that up to 70% of the gold is gravity recoverable and the results indicate even higher gravity recoveries could be possible with further optimization.

Resource Estimate Update

Mercator Geological Services Ltd. based in Dartmouth, Nova Scotia, are conducting an independent resource estimate study on the Thor Trend. A site visit including independent check sampling of drill core has been completed by Mercator as part of the due diligence work.

The 2010 drilling program at Viking was extended longer than initially anticipated due to positive drill results and the program being under budget. As a result delivery of data to be included into the resource estimate study was continued until mid-November. Providing that no technical difficulties arise during modeling, the study should be complete and ready for public disclosure in middle to late January. As per the requirements of NI 43-101 a detailed technical report is expected to be filed within 45 days after the public release of the resource estimate data.

Viking Trend Exploration

The Viking Trend is located 2 kilometres west of the Thor Trend along the western side of the Viking property and it is the only exploration target on the property that has seen significant drilling outside the Thor Trend. At the Viking Trend alteration and mineralization have been defined by surface work over an area 2000 metres long by 250 metres wide and the zone remains open along strike. Nine holes have recently been drilled into the zone and all holes confirm the presence of a large alteration zone containing highly anomalous gold over widths ranging from 47 to 108 metres.

Drilling highlights include 8 meters grading 0.5 g/t gold, 11.5 metres grading 0.4 g/t gold, 27.7 metres grading 0.3 g/t gold, and 73.5 metres grading 0.2 g/t gold. In addition to gold the zone contains highly anomalous silver, zinc, copper, and lead. Fifteen check samples of drill core from the Viking Trend were sent for re-analyses using a multi acid digestion procedure and analysing for a wider range of element. Silver grades in the check samples increased by 230% and the samples also contain anomalous bismuth, selenium, thallium, and tellurium.

To date drilling has only tested a small portion of the known strike length and down dip extent of the zone, leaving considerable opportunity for the discovery of higher grade sections.

The Viking Property

The Viking Property contains numerous high grade veins within larger bulk tonnage style zones of gold mineralization located within a 3 to 4 kilometre long gold-in-soil anomaly. Drilling highlights from previous drilling programs include high grade intercepts of 5.75 metres grading 33.7 g/t gold, 3.7 metres grading 50.1 g/t gold, 0.5 metres grading 218.8 g/t gold as well as lower grade intercepts including 27 metres grading 7.9 g/t gold, 23.0 metres grading 5.1 g/t gold, and 57.4 metres grading 2.8 g/t gold. The Viking property is located in the mining friendly jurisdiction of Newfoundland and Labrador and has excellent access and local infrastructure, with a paved highway and power line located less than one kilometre from the project. Northern Abitibi has a 100% property interest in the Viking project subject to a 2% to 4% sliding scale net smelter royalty held by Altius Resources. A detailed description of the Viking project is available on our website (www.naminco.ca).

Quality Control

All drill core is logged, photographed, and cut in half with a diamond saw. Half of the core is bagged and sent to Accurassay Laboratories or Eastern Analytical for analyses while the other half is archived and stored on site for verification and reference purposes. Gold is assayed by standard fire assay methods with additional elements analyzed by Induced Coupled Plasma (ICP). Samples with greater than 5 g/t gold and samples containing visible gold are re-assayed using a metallic sieve procedure to reduce the nugget effect created by free gold particles in the samples.

Duplicate samples, blanks, and certified standards are included with every sample batch and then checked to ensure proper quality assurance and quality control (QA/QC). Select samples are also sent to an outside laboratory for independent analyses as part of a check assay procedure.
