FOR IMMEDIATE RELEASE
Sama Graphite (SRG) Receives Very Favorable Characterization Test Results
The Graphite Concentrate from the Lola Deposit is Suitable for a Very Wide Range of
Applications
Montreal, Quebec, April 27, 2017 - Sama Graphite Inc. (TSXV: SRG) (“SRG” or the “Company”)
today announced the results of a ProGraphite GmbH (“PG”) technical investigation on the
Company’s 100% -owned Lola Graphite deposit in the Republic of Guinea, West Africa.
Laboratory work and analysis conducted by PG on the Lola Graphite concentrate returned
excellent results indicating that graphite from the Lola deposit is suitable for a very wide range of
graphite applications, including the important traditional markets like refractories, crucibles,
friction products, carbon brushes and sealing. Additionally, the combination of very favorable ash
composition, high crystallinity, high oxidation resistance and excellent purification behavior makes
the graphite very valuable for demanding new tech applications, including energy applications
and particularly with regard to spherical graphite for Lithium Ion Batteries.
ProGraphite Main Observations:
• The high proportion of large flakes of the concentrate is remarkable. Only very few flake
graphite deposits have such a high flake yield. This is a major advantage for the Lola
deposit, as the large flakes trade at significantly higher prices.
• The concentrate was screened to get particle size distribution information with very
favorable results: very coarse material, 2/3 of the graphite is large flake (+80 mesh), and
1/3 is “jumbo” flake material (+50 mesh).
• Compared to -100 mesh graphite of the same carbon grade, the market price for +50 mesh
material is more than double, which makes the Lola deposit much more valuable.
• Main elemental impurities are Si, Al and Fe, which is typical for flake graphite. Impurities
known to cause trouble in various applications, such like S or heavy metals are naturally
on very low levels in the Lola graphite concentrate.

• Key advantages of Lola graphite are t he favorable ash composition and the comparably
low efforts required to attain high carbon grades.
• The graphite is of very high crystallinity, which means that the graphite crystals are almost
perfect, making this graphite suitable for highly demanding applications like Lithium Ion
batteries or synthetic diamonds.
• Purification tests verified that the graphite could easily be upgraded with standard
processes to levels above 99.5%; with most elements, already under the limits for battery
application. The purification performed was “mild” compared to the “harsh” purification
usually applied for Lithium-Ion battery grade, thereby attesting again to the likelihood that
the material will be very suitable for such an application.
• The volatiles are low, oxidation resistance is very high and the specific surface area is in
the normal range.
• The graphite from the Lola deposit has a high bulk densi ty (>700 g/l), typical Chinese
graphite has bulk densities of 450-550 g/l for +80 mesh.
ProGraphite performed the investigation on a concentrate sample produced by Activation
Laboratory (Actlab) in Ontario. Actlab produced a first flash flotation concentrate from the typical
surface graphite rich material. No attempt to further purif y the concentrate was made at Actlab.
This was intentional as the Corporation wanted ProGraphite to investigate the most suitable
purification processes to be applied to the flash concentrate in determining and targeting various
markets and end uses.
SRG is continuing to work in close collaboration with PG and Actlab to refine metallurgical
processing for developing the most optimal flowsheet.
