Northern Abitibi Mining Corp. ("Northern Abitibi") (TSX VENTURE:NAI) is pleased
to announce the results of the first resource estimate for the Thor Trend
Deposit on the company's 100% owned Viking gold property in Newfoundland. The
independent mineral resource estimate study was conducted by Mercator Geological
Services Limited ("Mercator") and was completed in accordance with Canadian
Securities Administrators National Instrument 43-101 ("NI 43-101") and the CIM
Standards on Mineral Resources and Reserves.


The resource model evaluates low grade alteration based gold mineralization
separately from higher grade gold trends and vein based mineralization. Several
high grade solid models were created based on assay grades, and the associated
high grade values have been restricted to those solids. Larger low grade shells
constrain the interpolation of the surrounding lower grade mineralization where
grade and continuity have proven sufficient.


The tables below show the cut and uncut Inferred Resource estimate reported at a
series of cut off grades. Mercator determined that the low grade mineralization
demonstrates good continuity at the 0.20 grams per tonne (g/t) grade cut-off,
resulting in a cut Inferred Mineral Resource of 6.284 million rounded tonnes at
a grade of 0.61 g/t gold (123,242 ounces), and an uncut Inferred Mineral
Resource of 6,293,000 million rounded tonnes at a grade of 0.65 g/t gold
(131,511 ounces). The effective date for this estimate is March 2nd, 2011.

(i)High grade domains are spatially constrained but not capped. Low grade
domains not capped.


Mineral resources are not mineral reserves and by definition do not demonstrate
economic viability. There is no certainty that all or any part of the mineral
resource will be converted into mineral reserves.


Highlights



--  The deposit remains open along strike and to depth. 
--  In-fill drilling guided by data from the resource estimate can
    potentially add additional gold resources at low incremental costs per
    ounce. 
--  The modeling has resulted in a much improved understanding of the
    geometry of high grade zones which are proving to be coherent bodies
    with good continuity. Most of the high grade zones were not specifically
    targeted during past drilling programs which were designed to evaluate
    the bulk minable potential of the system. Excellent potential to add
    significant additional high grade gold resources by specifically
    targeting the high grade zones within the deposit envelope has been
    identified. 
--  The deposit is near surface and has a favorable open pit geometry. 
--  Total discovery cost for each ounce of gold at the Viking Project is
    $21/ounce. 



Dr. Shane Ebert, President of the Company commented "Northern Abitibi has
discovered a significant new gold resource with excellent initial metallurgical
results that is located adjacent to roads, power, and a potential work force in
the mining friendly jurisdiction of Newfoundland. The resource estimate shows a
very significant tonnage of mineralized material and there remains excellent
potential to increase this tonnage with further drilling within the current
deposit envelope, and exploring the system to depth, along strike, and by
testing several other large gold targets on the property. In deposits with
coarse gold, such as Viking, diamond drilling is a good measure of geological
continuity but can be a statistically poor measure of grade and its
distribution. In several examples, drilling significantly understates
bulk-sample grades in deposits with coarse gold. Plans to further expand the
high grade resources and assess the grade of the deposit through bulk sampling
are underway."


Resource Details

The resource estimation project was carried out by Mercator Geological Services
Limited (Mercator) of Dartmouth, Nova Scotia and Independent Qualified Person
Michael P. Cullen, M.Sc., P. Geo. is responsible for the program. The estimate
is based on validated results of 13,922 metres of diamond drilling in 103 drill
holes carried out between October 2008 and November, 2010, and 1571 surface
channel samples. Modeling was performed using the Gemcom Surpac(R) 6.1.4
modeling software package with grades estimated by inverse distance squared
interpolation from 1.0 meter down hole assay composites combined with the
channel samples. Block size was 5 meters (x) by 5 meters (y) by 5 meters (z)
with sub-blocking at 2.5 meters (x) by 2.5 meters (y) by 2.5 meters (z).


Grade interpolation was constrained according to grade shell wireframes
utilizing multiple independent search ellipse passes. High grade mineralization
was constrained in 9 solid models with two primary orientations, north-south
striking dipping to the west (Thor Trend) and east-west trending plunging to the
southwest (Thor Vein). Contributing values were capped at 28 g/t and
interpolated predominantly using search ellipses with a major axis range of 50
meters, a semi-major axis of 25 meters, and a minor axis of 10 meters. The
surrounding low grade mineralization demonstrating continuity at a 0.20 g/t
threshold was constrained in 3 solid models oriented along the primary north
south Thor Trend (345 to 350 degree strike) with a westerly dip (65 to 70
degrees). Contributing values were capped at 5 g/t and interpolated using search
ellipses with a major axis range of 100 meters, a semi-major range of 50 meters,
and a minor axis range of 25 meters. Peripheral low grade mineralization without
the sufficient demonstrated continuity was interpolated using a search ellipse
oriented along the primary Thor Trend constrained to a 50 meter major and
semi-major axis range, representing the nominal drill hole section spacing, and
a 10 meter minor axis range. A specific gravity factor of 3.00 grams per cubic
centimeter was assigned to diorite litho-coded blocks and a factor of 2.70 grams
per cubic centimeter was assigned to all other blocks, based on the average
results of specific gravity determinations from Northern Abitibi. All resources
are categorized as being in the inferred category.


A complete Technical Report on the Thor Trend Deposit describing in detail,
among other things, the resource estimate, QA/QC, database validation and
geologic model, is expected to be filed on SEDAR by April 16, 2011.


The Thor Trend

The Thor Trend Deposit on the Viking Property is hosted by hydrothermally
altered, foliated granitoid rocks of Proterozoic age that are cut by two large
diorite sills and gold mineralization of economic interest has been encountered
within all major rock types on the property. Low grade gold mineralization at
levels between 0.10 g/t and 0.50 g/t has been defined by current drilling along
approximately 550 meters of strike length and remains open to both north and
south as well as down dip. High grade domains within the low grade halo have
been modeled as six separate zones to date that were defined on the basis of
drill core and channel sample assay results. Influence of high gold grades was
restricted to spatial solids developed to define the trends. The larger low
grade shell that surrounds the higher grade zones was modeled separately.


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.
