Northern Abitibi Announces Additional Drill Results from Viking Including 1.1 Metres Grading 6.9 Grams Per Tonne Gold and 21.4 Metres Grading 0.9 Grams Per Tonne Gold

CALGARY, ALBERTA--(Marketwire - July 27, 2011) - Northern Abitibi Mining Corp. (TSX VENTURE:NAI) ("Northern Abitibi") is pleased to provide assay results for drill holes 110 to 115 from its ongoing drill program at the Viking gold property in Newfoundland.

Drilling Program

A total of 3600 metres of drilling in 16 holes has been completed to date during the 2011 drilling program. All of this drilling has been focused on expanding and infilling the Thor Trend resource area, and this phase of the drill program is nearly complete. In early August the drill will start testing targets outside of the Thor Trend.

Results from holes 110 to 115 are summarized in the table below. Drilling continues to expand the lower grade envelope to depth and along strike as highlighted in holes 112 and 114 which intersected 25.4 metres of 0.7 grams per tonne (g/t) gold and 21.4 metres of 0.9 g/t gold respectively. Additional higher grade quartz-sulfide veins have also been intersected including 1.1 metres grading 6.9 g/t gold in hole 112, and 1.7 metres grading 4.3 g/t gold in hole 115.

Exploration Update

This year to date 16 new core holes have been completed (holes 104 to 120) and hole 121 is currently in progress. Assay results have been received for holes 104 to 115 and holes 116 to 120 have been logged and sampled and sent to the lab for assay.

During the 2011 field program seven trenches have been excavated, mapped, and sampled. Assay results have been received for 3 trenches which are located about 400 metres north of the Thor Trend resource. These trenches have uncovered several zones of alteration and low grade to anomalous gold mineralization over 10's of metres of width, with the best assays returning 1.0 g/t gold over 1.1 metres and 0.5 g/t gold over 1.1 metres. The significance of this new discovery is currently being evaluated for follow up exploration. Additional trench results should be available in the coming weeks.

An induced polarization geophysical survey is currently in progress at Viking and should be complete by August 10^th, with results anticipated in mid to late August. Any significant geophysical anomalies identified by the survey will be drill tested in late August.

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 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 Thor Trend contains an uncut Inferred Mineral Resource containing 131,511 ounces of gold, 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 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.
