Focus Graphite Inc. (TSX VENTURE:FMS)(OTCQX:FCSMF)(FRANKFURT:FKC) ("Focus" or
the "Corporation") is pleased to report that the final Phase II Locked Cycle
Test(i) (LCT) metallurgical results performed at SGS Canada Inc., in Lakefield,
Ontario, continue to confirm an average concentrate grade of 96.4% C and a high
average flake graphite recovery of 92.5% for its Lac Knife high-grade graphite
deposit located near Fermont, Quebec.
SGS Canada Inc. ("SGS") has completed all six (6) Phase II locked cycle tests
(LCTs) on composite core samples comprised of low-grade, semi-massive, and
massive graphite mineralization with a head grade ranging between 6.0% C and
25.0% C.
Highlights of these test results are as follows:
-- The carbon content of graphite concentrates produced from the six (6)
composites averaged 96.4% C, including the finest graphite flake
concentrate (-200 mesh) produced. This is a 4.4% increase over Phase I
LCTs completed in mid-2012.
-- The average graphite flake recovery for the overall deposit following
the final Phase II LCT's increased to 92.5% which confirms the previous
four (4) tests and increases the recovery by 0.3% from the previous
results.
-- The proportion of large flakes (+80 mesh) recovered from the low grade,
semi massive, and massive types of mineralization (total: six (6)
graphite concentrate samples) ranges between 35% and 58%;
-- The Phase II LCT program produced consistent results for all of the
composite samples that were tested representing the mineralization
types, which confirms the suitability of the proposed concentrator flow
sheet to process these different types of mineralization within the Lac
Knife deposit, namely the low-grade, semi-massive, and massive graphite
mineralization;
-- A series of comminution tests generally characterized the seven (7)
composite samples (six (6) mineralization and one (1) waste host rock)
that represent the deposit, to require a low consumption of energy per
tonne processed (kWhr/t). Further testing will establish this more
precisely which will be favourable for the crushing and grinding circuit
design and operational costs per tonne;
-- Detailed chemical analysis of the final concentrates did not identify
any impurities that are normally considered deleterious.
-- In addition, a LCT was completed on a composite sample of the deposit's
host rock grading 1% C. The concentrate grade obtained was also very
good at 96%C with a flake graphite recovery of 94.5%. These results
suggest that mining dilution would not impact the recovery nor the final
concentrate grade and quality in a negative way;
(i) A locked cycle test is a repetitive batch flotation test conducted to assess
concentrator flow sheet design. It is the preferred method for arriving at a
metallurgical projection from laboratory testing. The final cycles of the test
are designed to simulate a continuous, stable flotation circuit.
"These metallurgical test results were incorporated into the flow sheet design
for the pilot plant tests that were completed in early May. The final pilot
plant results are now pending and we hope to communicate this soon." said Dr.
Joseph Doninger, Director of Manufacturing and Technology for Focus Graphite.
The purpose of the pilot plant is to confirm the results obtained following the
LCT test program and also to produce marketing samples of graphite flake for end
user evaluations and generate graphite raw materials for second transformation
testing. Pilot plant test results are pending.
Focus President and CEO Gary Economo said: "These latest results continue to
confirm that Lac Knife is an exceptional flake graphite deposit. These increased
recovery levels are resulting in a very high carbon content for all of the
concentrates produced, even for the finest (-200 mesh) graphite flake
concentrate which could provide a low cost raw material that can potentially be
upgraded further to meet the specification limits of high purity carbon that the
lithium-ion battery manufacturers require. This will further our discussions
with potential end users for off-take agreements. It supports our focus on the
lithium-ion battery market for high technology transportation and energy
applications which is an objective of the Quebec Government. This will also
allow us to use the much higher-priced large graphite flakes for other
high-technology applications."
All carbon analyses were performed by SGS and are reported as total carbon (C).
The analytical methods that were used to determine the metallurgical results on
the final concentrates included double loss on ignition analysis (double LOI)
and total carbon analysis by Leco. The lower grade tailings products were
analyzed by the graphitic carbon method to discount the organic carbon and
carbonate carbon in the samples.

About Focus Graphite
Focus Graphite Inc. is an emerging mid-tier junior mining development company, a
technology solutions supplier and a business innovator. Focus is the owner of
the Lac Knife graphite deposit located in the Cote-Nord region of northeastern
Quebec. The Lac Knife project hosts a NI 43-101 compliant Measured and Indicated
mineral resource of 4.972 Mt grading 15.7% carbon as crystalline graphite with
an additional Inferred mineral resource of 3.000 Mt grading 15.6% crystalline
graphite. Focus' goal is to assume an industry leadership position by becoming a
low-cost producer of technology-grade graphite. On October 29th, 2012 the
Company released the results of a Preliminary Economic Analysis ("PEA") of the
Lac Knife project which demonstrates that the project has an excellent potential
to become a producer of graphite. As a technology-oriented enterprise with a
view to building long-term, sustainable shareholder value, Focus invests in the
development of graphene applications and patents through Grafoid Inc.
