Northern Graphite Corporation (TSX VENTURE:NGC)(OTCQX:NGPHF) is pleased to
announce the results of its bankable feasibility study ("FS") for its 100% owned
Bissett Creek graphite deposit. The FS was prepared by GMining Services Inc. and
included contributions from SGS Canada Inc. (Lakefield-metallurgy and
Geostat-resource modelling), Knight Piesold Ltd. (environmental, permitting,
tailings management and road infrastructure) and Met-Chem Canada Inc. (process
engineering). A conference call will be held at 9:00 am Eastern Standard Time,
on July 10, 2012 to discuss the FS results (see details below). A National
Instrument 43-101 technical report relating to the FS will be filed on SEDAR
within 45 days of this news release.
Gregory Bowes, Chief Executive Officer, commented that: "The FS confirms the
technical and financial viability of constructing and operating an open pit mine
and a 2,300tpd processing plant on the Bissett Creek property and establishes
Northern Graphite as an industry leader with a large flake, high purity,
scalable deposit that is located close to infrastructure and has very
competitive operating costs". He added that "This is a conservative and
realistic study that indicates the project has attractive economics and that
there are a number of immediate, low risk opportunities to further enhance
project returns."

Prices of US$2,100 and US$2,600 per tonne of concentrate represent the 24 and 12
month weighted average price for the various sizes and grades of flake graphite
that will be produced from the Bissett Creek deposit, based on prices quoted by
Industrial Minerals Magazine. Prices of US$2,300/t and US$2,800/t represent the
24 and 12 month weighted average prices with the inclusion of a conservative 10%
premium over +80 mesh large flake graphite prices for the +50 mesh (XL) and +32
mesh (XXL) flake components that will make up approximately 50% of Bissett Creek
production. The Company believes that it will realize premiums in excess of 20%
over the price of standard large flake graphite based on historical pricing for
XL and XXL flake graphite.
Project Description
The proposed development of the Bissett Creek graphite deposit includes the
construction of an open pit mine, a 2,300tpd flotation processing plant based on
92% availability, a natural gas fueled power generating plant and associated
infrastructure. The processing plant will consist of conventional crushing,
grinding and flotation circuits followed by concentrate drying and screening.
The Company plans to build a natural gas pipeline to the site from the main
Trans Canada line which is approximately 15 kms away. The natural gas will fuel
five 1.0 MW-generators to produce electrical power and waste heat from the
generators will be used to dry the concentrate. This will result in low overall
energy costs. Infrastructure includes upgrading the last 5 kms of access road,
site preparation, and building a non-acid generating tailings facility and a
very small sulphide tailings facility. The processing plant will include
sulphide flotation at the end of the circuit to remove enough sulphides to make
approximately 97% of the tailings benign. After year 12 of operation, the
sulphide tailings will be moved to the bottom of a mined out pit for permanent
storage under water. Sulphide tailings and non-sulphide tailings will
subsequently continue to be deposited in a mined out pit for the balance of the
mine life which will result in a low final closure costs.
Resources and Reserves
Probable mining reserves for the Bissett Creek deposit were established based on
indicated resources estimated as at September, 2011 by Francois Thibert, M.Sc.
P. Geo. from SGS Canada Inc. (Geostat), an independent qualified person under NI
43-101, using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM)
Standards on Mineral Resources and Reserves, Definitions and Guidelines (see
Table 2).

Mineral resources that are not mineral reserves do not have demonstrated
economic viability
G Mining established a breakeven cut-off grade ("COG") and ran optimized Whittle
pits on the indicated resources based on a number of parameters including those
outlined in Table 1. The final mine plan resulted in a probable reserve of 19.0
million tonnes of ore grading 1.89% graphitic carbon ("Cg") based on a cut-off
grade of 1.2% Cg. In order to increase head grades in the initial years of
production while maintaining a reasonable stripping ratio, ore between 1.2% Cg
and 1.6% Cg will be partially stockpiled and added to the mill feed at a later
date. The mine plan was also designed to supply blasted rock and glacial till
for tailings dam construction during pre-production and to allow for tailings
disposal in mined out areas by year 13 for sulphide tailings and year 16 for
non-sulphide tailings. A mining recovery factor of 90% and a dilution factor of
7.8% at a grade of 0.5% Cg were applied.
Metallurgy
SGS-Lakefield has completed the full suite of metallurgical tests on the Bissett
Creek deposit including lab and bench scale work, a bulk sample/pilot plant
test, and variability testing to ensure recoveries and flake size distribution
are consistent across the deposit. A similar program was also carried out in the
1980s as part of a previous feasibility study (non NI 43-101 compliant) with
consistent results.
The FS is largely based on pilot plant results from the processing of slightly
weathered material that does not respond as well to flotation as unweathered
rock. The locked cycle tests, which were performed on fresh drill core, were
better in terms of recoveries, concentrate grades and flake size distribution
which represents potential upside in the project.
The FS assumes recoveries of 92.7% in the first year of operation, 93.7% in year
two and 94.7% over the balance of the project. Recoveries in the eight
locked-cycle test averaged 97.2% and ranged from 95.2% to 99.1%.
The FS assumes an average concentrate grade of 94.5% compared to 94.9% in the
locked-cycle tests. However, the locked cycle tests generated average grades of
98.1%, 97.0% and 95.1% for the important +32 (XXL), +50 (XL) and +80 (L) mesh
size fractions respectively.
Based on pilot plant results, the FS assumes that production will consist of 18%
+32 mesh at 95.1% C, 31% +50 mesh at 95.1% C, 28.2% +80 mesh at 94.5% C, 5% +100
mesh at 97.3% C, 7% +150 mesh at 98% C and 11% -150 mesh at 92.7% carbon.
Production
Over the first five full years of operation a total of 4.2 million tonnes of ore
will be processed at an average head grade of 2.22% Cg to produce an average of
18,600 tonnes of graphite concentrate at 94.5% C per year. Over the 23 years of
operations contemplated in the FS, the mine will produce an average of
approximately 15,900 tonnes of graphite concentrate (94.5% C) per year which
includes processing of the low grade stockpile.
Operating Costs
Over the first five years, cash mine operating costs will average CDN$851 per
tonne of concentrate. Over the life of the project operating costs are estimated
at $968 per tonne of concentrate. These estimates are based on operating costs
per tonne of ore of $9.60 for processing, $2.94 for general and administrative
costs and $5.79 for mining.
Capital Costs
The capital cost to construct the processing plant, power plant and all
associated mine infrastructure is estimated at $93.5 million before contingency.
The total capital cost, including a $9.4 million contingency, is $102.9 million
(Table 3). In some instances the Company chose options that increased the
capital cost but reduced operating costs and improved the overall project
economics. In addition, the Company is required to post a financial assurance
with the Province of Ontario to guarantee its obligations with respect to the
Mine Closure Plan ("MCP"). The amount and timing of the financial assurance is
currently being negotiated.

Project Opportunities
It is the opinion of Northern Graphite management that a number of significant,
low risk opportunities exist to improve upon the FS. A 10% increase in grade and
a 10% reduction in operating costs for example, both of which management
believes are achievable for the reasons outlined below, would increase the pre
tax IRR by up to 20% and the NPV by up to 40%.
1. The final pit includes approximately 1.5 million tonnes of inferred
resources grading 1.54% Cg which are treated as waste. The processing of
this material would reduce the stripping ratio and mining costs and
improve cash flows.
2. The mine plan does not consider inferred resources outside the pit where
significant tonnages in excess of 2% Cg exist. Upgrading these resources
to indicated and including them in a revised mine plan, instead of
processing the low grade stockpile, would reduce costs, greatly extend
the mine life, and further enhance the economics of the deposit. The
Preliminary Economic Assessment on the Bissett Creek project states
there is a relatively high probability that inferred resources can be
upgraded due to the thick, flat lying and continuous nature of the
mineralization in the Bissett Creek deposit. Mineral resources that are
not mineral reserves do not have demonstrated economic viability.
3. Actual graphite production from the pilot plant was approximately 4%
higher than indicated by the assayed head grade of the bulk sample while
graphite production from eight locked cycle tests was approximately 12%
higher than the assayed head grades. The bulk sample consisted of
partially weathered near surface material which does not respond as well
to flotation while the locked cycle tests were performed using fresh
drill core. Therefore, the reserve grade is considered conservative and
potentially understated. Further investigation of assay procedures and
mineralogy is planned to explain the understatement but sufficient
testing has been done for the Company to conclude that the performance
of the mill will likely exceed levels used in the FS.
4. The FS assumed contract mining. It is highly likely the Company will buy
and operate its own mining fleet. The incremental capital cost is
approximately $7 million but with lease financing, and 20% down payment,
the incremental financing requirement is approximately $1.4 million.
Owner mining would reduce operating costs by approximately $50 per tonne
of concentrate.
5. The Company expects to achieve 95% mill recoveries earlier than
projected in the FS and ultimately to exceed the 95% level and to do
better than the 92% mill utilization rate used in the FS.
6. The Company's business plan is to significantly expand production in the
future by incorporating inferred resources and to reduce unit costs
below $800/tonne of concentrate. Inferred resources are considered too
speculative geologically to have the economic considerations applied to
them that would enable them to be categorized as mineral reserves, and
there is therefore no certainty that the Company's business plan in this
regard will be realized. Mineral resources that are not mineral reserves
do not have demonstrated economic viability.
7. There is scope to reduce capital costs through the purchase of used
equipment, lease financing of the natural gas generators, and additional
permitting to provide access to lower cost tailings options.
8. The Company has successfully upgraded graphite concentrate from the
Bissett Creek deposit for use in Lithium ion batteries and other high
purity markets. Testing is ongoing and will assist the Company in
defining the capital and operating costs associated with constructing an
upgrading facility. No revenues or costs associated with upgrading and
selling into value added markets are included in the FS. Industrial
Minerals Magazine recently reported that spherical graphite used in
Lithium ion batteries sells for US$6,000-8,000 per tonne.
Environmental, Permitting and Local Community
The Company expects to file its Mine Closure Plan ("MCP") with the Ministry of
Northern Development and Mines ("MNDM") within three weeks. The MCP is a
comprehensive document that describes in detail the scope of the project
including the nature of mining and processing operations, buildings and
infrastructure, potential effects on the environment, mitigation measures to
protect the environment, a description of First Nation, government agency and
local community consultation, and the Company's plan to rehabilitate the site
and return it to its natural state at the end of operations including an
estimate of the cost of doing so. The Company is required to post a financial
assurance to ensure that funds are available to complete the closure plan. The
MNDM has 45 days to respond and the Company anticipates that acceptance and
approval of the MCP will be received by the end of the third quarter of this
year. Approval of the MCP will enable the Company to initiate construction and
to apply for a number of other permits that relate to operations.

The Graphite Market
Graphite production and exports from China, which produces 70% of the world's
supply, are expected to decline and an export tax and a licensing system have
been instituted. As a result, both the European Union and the United States have
declared graphite a supply critical mineral and end users are actively seeking
secure, alternative sources of quality supply.
Graphite demand and prices have increased substantially over the past few years
due to the ongoing modernization of China and other emerging economies which has
resulted in strong demand from traditional steel and automotive markets. In
addition, new applications such as lithium ion batteries, vanadium redox
batteries, fuel cells and nuclear power have the potential to create significant
incremental demand growth. The manufacturing of Li ion batteries requires up to
30 times more graphite than lithium and their use in the growing EV/HEV market
is expected to require significant increases in graphite production.
Northern Graphite Corporation
Northern Graphite Corporation is a Canadian company that has a 100% interest in
the Bissett Creek graphite deposit located in eastern Ontario. Northern Graphite
is well positioned to benefit from this compelling supply/demand dynamic with a
high purity, large flake, scalable deposit that is located close to
