Northern Gold Mining Inc. (TSX VENTURE:NGM) ("Northern Gold" or "the Company")
announces the results of an updated resource estimate for its Garrison Property
(Garrcon and Jonpol deposits). This NI 43-101 report, being independently
prepared by A.C.A. Howe International Limited ("Howe") of Toronto, Ontario, was
focused on tightening the model constraints to reflect current gold pricing and
the latest infill and step out drilling completed by the Company since the last
resource update announced on April 19, 2012. "Northern Gold's efforts have
continued to confirm a significant gold resource at Garrcon, with both an open
pit and underground potential. Geologic constraints from the infill drilling
provided tighter mineralized domains, as well as the delineation of waste
domains", according to Howe. A Whittle model pit shell was based on $US 1,250
per troy ounce gold pricing, 0.4 g/tonne block model cutoff, 55 degree pit wall
slope, a top cut of 112 g/tonne Au (high grade domains) and 114 g/tonne Au (low
grade domains) applied to individual (non-composited) assays, a resource
database utilizing primary assays only (except where historic core was relogged
and historic assays were duplicated, in which case the latter were used), domain
specific directional ellipsoidal searches were used for block grades, and mine
pit parameters developed in the 2011 PEA (Preliminary Economic Assessment, see
press release June 23, 2011). Material within this optimized pit, and
mineralization within 200 meters of surface have been categorized as open
pitable resources. The open pitable resource comprises 29,200,000 tonnes grading
1.12 g/tonne containing 1,047,000 ounces of gold (measured and indicated), and
an additional 1,700,000 tonnes grading 0.72 g/tonne containing 39,000 ounces of
gold (inferred); all in-pit resources have an approximate stripping ratio of
1.8:1 (waste to resource). This optimized pit shell was further used to define
those blocks below 200 metres, but outside of the pit shell and having a block
model cutoff of 1.5 g/tonne, as being an inferred underground resource of
5,10,000 tonnes averaging 3.49 g/tonne and containing 577,000 ounces of gold.
The full NI 43-101 Technical Report, along with plan and sections will be filed
on SEDAR within 45 days.
"Northern Gold continues to progress its plans to develop a producing gold mine
on its Garrison property, by de-risking the project. The updated Garrcon
resource, despite significantly tightening the model constraints, showed
increased grades in all three resource categories. This continues to demonstrate
the robust nature of the deposit and its viability as an open pit mine, and an
underground opportunity with unbounded depth potential. Plans, budgets and Mine
Closure Plans (permits) are being prepared in support of mining and offsite toll
milling of up to 150,000 tonnes from the Garrcon surface outcrop (see press
release dated January 16, 2014). This "proof of concept" testing will provide
valuable mining and milling "real world" data. Upon successful completion of the
bulk sample testing a Feasibility Report will be prepared in the fall.", said
Martin Shefsky, interim President & CEO of Northern Gold.

This is a summary table for the Garrison Property (Garrcon and Jonpol deposits).
Mineral resources are not mineral reserves and by definition do not demonstrate
economic viability. This mineral resource estimate includes inferred mineral
resources that are normally considered too speculative geologically to have
economic considerations applied to them that would enable them to be categorized
as mineral reserves. There is also no certainty that these inferred mineral
resources will be converted to the measured and indicated resource categories
through further drilling, or into mineral reserves, once economic considerations
are applied.
For this NI 43-101 resource update (as compared to the 2012 resource update)
Howe reviewed the entire assay data set (the initial resource estimate as filed
on SEDAR November 5, 2010, and the PEA filed on August 8, 2011, as well as the
drill data listed in the June 5, 2012 SEDAR filling for the last resource
update, and finally the latest infill and step out drilling including 54
historic drill holes (1985 to 2007), 256 Northern Gold drill holes and 18 drill
hole extensions (2009 - 2012 - up to GAR-12-270) and determined that utilizing
primary assays (except where historic assays are duplicated by Northern Gold new
core logging and assay, in which as the latter is used), limits the potential
for the introduction of systematic bias and the artificial 'smoothing' of assay
grades by averaging. A top-cut of 112 g/tonne Au (high grade domains) and 114
g/tonne Au (low grade domains) was then applied to individual (non-composited)
assays. Howe increased the block model cut-off grade from 0.3 g/tonne to 0.4
g/tonne. Based on Howe's statistical review (4,076 measurements) of ongoing
specific gravity (SG) testing by Northern Gold, the average SG was increased
slightly from 2.79 g/cm3 to 2.80 g/cm3 for the mineralized resource blocks. The
new drilling (both in-fill and step-out) confirmed the uniformity of the
mineralization, as well as identified "defined waste blocks"; all domain
modeling is constrained by interpreted geology. Howe's domains were subjected to
individual geostatistic review, which resulted in domain specific directional
ellipsoidal searches used to estimate block grades (as opposed to
omni-directional search in the previous two resource updates). The majority of
these ellipsoidal searches are approximately 2:2:1 (x:z:y).
As detailed above, the Whittle model pit shell (optimized pit) was based on a
0.4 g/tonne Block model cutoff grade and optimized for $US 1,250/troy oz gold,
55 degree pit wall slope, and utilized the 2011 PEA pit mine parameters. The
resultant resource estimate for the conceptual open pit has a waste to resource
strip ratio of 1.8:1 (about 10% lower than the 2011 PEA of 2.0:1). The block
cut-off grade for inferred underground (greater than 200 m depth outside of the
optimized pit shell) was 1.5 g/tonne. Note that mineral resource tonnes quoted
are not diluted.

Notes on 2014 Garrcon Mineral Resource Estimate:
1. Mineral Resources are calculated with commercial mining software. Drill
holes traces showing lithology and gold grade were reviewed in plan and
cross section.
2. The resource estimate has been prepared by Leon McGarry, B.Sc., P.Geo.,
ACA Howe Geologist.
3. Cut-off grade for mineralised zone interpretation is 0.1 g/tonne.
4. Block cut-off grade for potential open pitable Mineral Resources is 0.4
g/tonne. Block cut-off grade for potential underground (greater than 200
m depth) Mineral Resources is 1.5 g/tonne.
5. Top-cuts of 112 g/tonne Au (high grade domains) and 114 g/tonne Au (low
grade domains) applied to individual (non-composited) assays.
6. Gold price for the purpose of the resource estimate is $US 1250 per troy
ounce.
7. Zones extend up to 100 metres down-dip from the last intercept. Along
strike, zones extend halfway to the next cross-section.
8. Minimum width is 5 metres, though in no place is the zone that narrow.
9. A specific gravity (bulk density) value of 2.8 is applied to all blocks
- a representative value based on 4,076 measurements.
10. Wireframe constrained block model grade interpolation has been
undertaken using Ordinary Kriging (OK).
11. Measured mineral resources are defined where three holes are used to
estimate block grades and the average distance to samples was 36 metres
or less. Indicated mineral resources are defined where three holes are
used to estimate block grades and the average distance to samples was 73
metres or less.
12. Mineral Resource tonnes quoted are not diluted.
13. No mineral reserves are identified.
14. Tonnes and ounces have been rounded to reflect the relative accuracy of
the mineral resource estimate; therefore numbers may not total
correctly.
15. Mineral resources are not mineral reserves and by definition do not
demonstrate economic viability. This mineral resource estimate includes
inferred mineral resources that are normally considered too speculative
geologically to have economic considerations applied to them that would
enable them to be categorized as mineral reserves. There is also no
certainty that these inferred mineral resources will be converted to the
measured and indicated resource categories through further drilling, or
into mineral reserves, once economic considerations are applied.
16. 1 troy ounce equals 31.10348 grams.
17. The volume/tonnes of volumetrically insignificant historical underground
exploration workings have not been subtracted from this mineral resource
Jonpol Deposit Mineral Resources
This is the first "new" Jonpol deposit resource update for Northern Gold since
the property was acquired from Val Gold in 2009, and the historic NI 43-101
technical report on the 1996-1999 Hillsborough Resources and Valgold 2005-2007
work was filed on SEDAR on October 29, 2009. In addition to new drilling
completed by the Company (66 holes and 9 drill hole extensions (2011-2013)) the
biggest change to the resource update was the use of geologically interpreted 3D
wireframe block model grade interpolation that has been undertaken using
Ordinary Kriging (OK). Domain specific directional ellipsoidal searches are used
to estimate block grades, as opposed to the simple 2D longitudinal polygons.
Furthermore a cut-off grade for mineralized zone interpretation of 3 g/tonne of
gold over a minimum width of 1.5 metres was used in the new resource, verses a
cut-off grade for zone interpretation of approximately 0.5 g/tonne of gold in
the previous report. Unfortunately many of the historic holes lacked a downhole
survey and have had to be assumed to have no deviation.
This has resulted in an indicated resource estimate with a 344% increase in
resource tonnes (872,000 vs 253,100), but a 2.43 g/t decrease in grade (due to
the change in the block model cutoff, and minimum mining width), and a 237%
increase in gold ounces (150,000 oz Au vs 63,200 oz Au, a 86,800 oz increase).
The inferred resource tonnage estimate decreased by 482,800 tonnes, but the
average grade increased by 0.63 g/tonne to 5.56 g/tonne, resulting in a slight
decrease in gold ounces (-54,540 ounces gold) to 192,000 ounces gold.

Notes on 2014 Jonpol Mineral Resource Estimate:
1. Mineral Resources are calculated with commercial mining software. Drill
holes traces showing lithology and gold grade were reviewed in plan and
cross section.
2. The resource estimate has been prepared by Leon McGarry, B.Sc., P.Geo.,
ACA Howe Geologist.
3. Mineralised zone interpretation based on a minimum grade of 3 g/tonne Au
over a minimum true width of 1.5 metres.
4. Block cut-off grade for potential underground Mineral Resources is 3
g/tonne.
5. Top cut of 100 g/tonne Au applied to non-composited assays in the East
Zone. No top-cut applied in other zones. In zones other than the East
Zone, assay database grade distributions are not skewed by erratic high
values and assays are generally well constrained by wireframes and drill
hole distribution. In ACA Howe's opinion the use of a top cut will not
significantly affect the results in these zones.
6. Gold price for the purpose of the resource estimate is $US 1250 per troy
ounce.
7. Zones extend up to 50 metres down-dip from the last intercept. Along
strike, zones extend halfway to the next cross-section.
8. A default average specific gravity (bulk density) value of 2.8 has been
used.
9. Wireframe constrained block model grade interpolation has been
undertaken using Ordinary Kriging (OK).
10. Indicated mineral resources are defined where the mineralized zones
exhibited good continuity between drill holes on section and along
strike and are informed by 3 or more holes spaced less than 50 metres
apart.
11. Mineral Resource tonnes quoted are not diluted.
12. No Measured Resources or Mineral Reserves of any category are
identified.
13. Tonnes and ounces have been rounded to reflect the relative accuracy of
the mineral resource estimate; therefore numbers may not total
correctly.
14. Mineral resources are not mineral reserves and by definition do not
demonstrate economic viability. This mineral resource estimate includes
inferred mineral resources that are normally considered too speculative
geologically to have economic considerations applied to them that would
enable them to be categorized as mineral reserves. There is also no
certainty that these inferred mineral resources will be converted to the
measured and indicated resource categories through further drilling, or
into mineral reserves, once economic considerations are applied.
15. 1 troy ounce equals 31.10348 grams.
16. A bulk-sampling program on 4 sub-levels in the central part of the JP
Zone was completed in 1996-97 with a total of approximately 50,640
tonnes extracted, which produced 13,564 ounces of gold for an average
recovered grade of 8.3 grams of gold per tonne. This is comparable to a
polygon some 80m in the along strike direction and 30m down dip believed
to be centred on the position of the bulk sample, that outlines 78,400
tonnes at a grade of 5.3 for some 13,550 ounces of gold which has been
discounted from the resource.
The Company has prepared an Advanced Exploration Closure Plan to dewater and
rehabilitate the Jonpol decline. However at this time the economics of such an
undertaking appear risky and the Company has chosen to focus its efforts on
moving its Garrcon open pit forward, as noted above. The Jonpol remains
strategically important to the Company as its mineralization remains open along
strike (East - West) as well as at depth. Metallurgical testing done in 2013
(see press release of September 26, 2013) indicates that the only refractory ore
is in the immediate area of the Shaft Zone. The recently acquired Lac Properties
property to the west provides an opportunity to add significantly to this
updated Jonpol resource. In addition the existing decline may provide
exceptional access for not only the Jonpol vein deposit, but the Garrcon
underground, the 903 Zone (to the south of the Jonpol shaft), and mineralized
metasediments that are just now being explored between these two areas (see
Hastings channel sample press release dated February 10, 2014).
To provide further information and continuity between the previous resource
estimates prepared on the Garrison property and this updated resource, the
following tables provide more detailed information:
