Northern Abitibi Drills 38 Metres Grading 0.9 Grams Per Tonne Gold and 0.5 Metres Grading 12.5 Grams Per Tonne Gold at Viking

CALGARY, ALBERTA--(Marketwire - Nov. 4, 2010) - Northern Abitibi Mining Corp. (TSX VENTURE: NAI.V) ("Northern Abitibi") is pleased to provide assay results for drill holes 89, 91, 94, 96, 98, 100, and 101 from the Viking gold property in Newfoundland.

The 2010 drilling program at Viking is now complete. During 2010 a total of 9735 metres of core in 58 holes has been drilled (holes 46 to 103) and the program was completed on schedule and under budget. To date Northern Abitibi has drilled 13,922 metres of core in 103 holes at the Viking Project and has collected sufficient drilling information to calculate an initial resource estimate on the Thor Trend gold zone, one of the project's five current exploration targets.

Drill Results - Thor Trend

Drill holes 89, 91, 94, 96, 100, and 101 were designed to infill and expand the known mineralized zone along the Thor Trend. The holes intersected strong zones of mineralization, including high grade intercepts, consistent with previous drill holes in the zone, and continue to demonstrate the strength and continuity of the gold zone (see table below). Highlights from the drilling include drill hole 100 which intersected a 38 metre zone averaging 0.9 g/t gold including a 15 metre zone averaging 1.3 g/t gold and a separate higher grade zone containing 7 g/t gold over 1 metre. Drill hole 101 also intersected a high grade vein containing visible gold which returned 12.5 g/t gold over 0.5 metres.

Drill hole 96 tested the northern part of the Thor Trend and has extended the mineralized zone further to the north. This hole encountered anomalous gold from 3.0 to 122.6 metres depth, with the best interval returning 10.0 metres grading 0.7 g/t gold including a 1.5 metre interval grading 1.6 g/t gold.

Other Targets - Initial Drill Tests

Drill hole 98 tested the Asgard Trend located about 200 metres east of the Thor Trend. The hole intersected zones of highly anomalous gold from 17.5 to 154.2 metres depth, with a high of 0.9 g/t gold over 0.4 metres. This single hole into the Asgard Trend confirms that the zone is gold-bearing and has significant size potential. Additional exploration along the known 500 metre strike length of the zone is warranted.

Dr. Shane Ebert, President of the Company commented "The 2010 drill program has successfully targeted and outlined an extensive near surface zone of gold mineralization along the Thor Trend on which resource estimate studies have commenced. Within this shallow gold zone numerous high grade shoots have been identified. The company and its independent consultants are now compiling the drilling information collected to date. With this information in hand, further planning for the delineation of Thor Trend high grade mineralization and expansion to depth, along with the testing of additional exploration targets, will be completed".

Exploration Update

Drill holes 88, 90, 92, 93, 95, 97, 99, 102 and 103 have been drilled into targets located outside the Thor Trend. These holes are expected to be ready for release shortly after full sets of assay data have been received and compiled.

The independent resource estimate study on the Thor Trend has now commenced. Mercator Geological Services Ltd. based in Dartmouth, Nova Scotia, are conducting the resource estimate which is scheduled to be complete before the end of this year.

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.
