Canada Carbon Achieves Exceptional 99.7% C(t) Graphite Flotation
Results Without Chemical Treatment
VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 22, 2014) -
Canada Carbon Inc. (the "Company") (TSX-VENTURE:CCB) is pleased to
provide the following update on the flotation concentration tests
for the Company's past-producing Miller Mine Graphite Property
hydrothermal graphite mineralization, being conducted by SGS Canada
Inc. ("SGS") at their facilities in Lakefield, Ontario.
As previously reported by press release dated May 1st, 2014, SGS
is conducting a metallurgical test program on a 50-kilogram
composite sample of the Miller hydrothermal graphite, with the
objective of developing a flotation concentration flow sheet which
optimizes the preservation of the crystalline graphite structure,
as well as particle size, in order to maximize the potential
economic value of this high-purity graphite. The following results
indicate that SGS has developed a clearer understanding of the
process optimization criteria, which will allow Canada Carbon to
begin scaling up the design of the pilot-plant processing equipment
for the previously reported 480-tonne bulk sample of the Miller
Mine hydrothermal graphite.
Presented below are summary statistics showing the success of a
variety of flotation trials, dating back to those reported
beginning July 18th, 2013. While Canada Carbon reported a
substantial increase in the yield of the largest graphite particles
from the initial flotation optimization trial on May 1st, 2014, the
Company now reports achieving a reproducible high yield of large
(+65 mesh) graphite crystals at a grade of 99.7% C(t), with the
application of the simple flotation and polishing techniques
already commonly employed in the natural graphite industry.

The 50-kilogram sample of Miller vein graphite which was the
subject of these flotation optimization trials was processed in
batches of approximately 2 kilograms each. With 80% of the original
sample still available for test processing, further flotation
optimization work may still be conducted before a final report is
issued by SGS.
Canada Carbon's Executive Chairman and CEO, Mr. R. Bruce Duncan,
commented, "We are tremendously pleased to receive these further
flotation optimization results from the team at SGS Lakefield. A
steady improvement in a number of variables, including the overall
concentrate grade (now in excess of 96%), the yield of large
graphite crystals (better than one third of the total concentrate,
by weight), but also the purity of those large crystals
(reproducible at 99.7%) indicate that the Miller hydrothermal
graphite has excellent processing characteristics. These
most-recent results reaffirm our belief in the truly exceptional
quality of the graphite hosted on our property. These high-purity
levels are required in many industrial applications including
electrochemical applications such as Lithium-ion batteries (used in
electric vehicles, portable electronics and cordless power tools),
which represents a significant and rapidly expanding market. The
current flotation trials have also increased the yield of
high-purity large crystals by 60%, to now represent more than one
third of the total yield, material which has previously been shown
to be upgradeable to exceed nuclear purity standards. Canada Carbon
can now confidently move forward with its plans to process the
480-tonne bulk sample, already permitted by the Government of
Québec."
