Berkwood Metallurgical Tests Yield 97.8% Graphite in Concentrate Grade

February 7, 2019, VANCOUVER, B.C. - Berkwood Resources Ltd. (TSX -V: BKR, FSE:
BK2, WKN: A110N3) (“Berkwood” or the “Company”) is pleased to announce that it has
received exceptional, positive test results from initial metallurgical testing undertaken to evaluate
whether the Lac Guéret South deposit is amenable to process ing for the ready separation of
graphite from the host rock. The work was carried out on two composite samples, each typical of
a principal mineralogical association in the graphite bearing geological formations of the Gagnon
Group. Metallurgical tests have demonstrated two highly desirable and advantageous features in
the graphite concentrates produced. The first advantage is the high abundance of coarse graphite
flakes recovered intact, and the second is high graphitic carbon grade of the concentrate produced.
Tom Yingling President and CEO states, “We are very happy with the superb results from our
metallurgical test work. We now have confirmed that we can produce highest -grade graphite
concentrates containing a high percentage of large flake product. With these positive metallurgical
results, I now look forward to integrating our recently completed fourth drill program dat a into
our geologic model: this work is expected to underpin an evaluation of requirements for the
preparation of a mineral resource estimate for publication. Berkwood is fully funded to complete
the required resource model, including any requirement for further drilling.”
Berkwood’s metallurgy program is being overseen by Technical Team Member Mr. Michel
Robert, B.A., B.A.Sc (Hons), M.A.Sc (Hons) . Michel is a metallurgist and mining engineer with
over 40 years of diverse technical management experience in the mining industry, from production
foreman through president for various companies involved in the base and precious metals,
industrial minerals, iron ore and niobium sectors.
Michel served for nine years at Teck Corporation as corporate metallurgist, lead engineer,
production superintendent and start-up manager. He was also a director of SNC (now SNC Lavalin
Group Inc.) and one of three founders of Simons Mining Group (now AMEC Foster Wheeler).
As Senior Vice President for Pan American Silver Corp. from 1995 to 2001, Michel managed
operations in Latin America and was responsible for the identification, purchase and turnaround
of numerous mines still running today.

Of significance to Berkwood’s Lac Guéret South Project is the fact that Michel was cofounder,
developer and metallurgist involved in the early stages of Quinto Exploration’s Graphite discovery
now being put into production by Mason Graphite (TSX -LLG). Berkwood’s Lac Guéret South
Graphite Project is located eight kilometers south of Mason Graphite’s project and shares a n
analogous geological environment , in an area where graphitic horizons range up to 40% Cg r
(averaging 20.4% at Mason Graphite’s Lac Guéret Deposit) and flakes of up to 5 mm in diameter
are exhibited. Large flake graphite is considered to be represented by flak es 0.3 mm in diameter
and above.
Michel Robert states, “Even when compared against a global suite of Graphite prospects, projects
and mines, it is extremely rare to see graphite concentrates that are readily processed to yield both
an abundance of large flakes AND high graphitic carbon grade . Berkwood’s initial Graphite
process samples have, to date, delivered on both these highly desirable and therefore potentially
valuable characteristics.”
Samples from our test, ready to be shipped to potential off take and project development partners
Berkwood retained the services of MET -SOLVE Laboratories Inc. to carry out initial mineral
processing testing program in mid 2018. This work comprised follow -up justified by the
compelling results achieved in the first Graphite Characterization Testing pro gram performed in
late 2017 early 2018 by MET-SOLVE.
Based on experience on similar projects gained by the professional team involved, it has been
possible to achieve significant early confirmation of excellent indicative metallurgical
characteristics featuring high recoveries of Cgr into concentrates of unusually high grade . The
work was carried out on two composite samples together comprising about 400 kg of material
from 41 samples taken from six drill holes. In total, thirty-six tests were carried out, including bulk
tests, to perform either calibration steps in the process design, or to run the complete chain of
selected processes. The process developed involves coarse grinding to nominal 20 US mesh (840
microns), classification, rougher -cleaner flotation , and gravity separation polishing. Flotation
reagents conditions were chosen to assure consistent results and simplicity. The procedure was
then tested on a 45 kg sample to produce concentrate samples for potential off-takers.
Two definite advantages of the graphite concentrates produced are a preponderance of coarse
flakes and high graphitic carbon grade as shown in the following table giving the results of the
final bulk test. Although test results are early stage , Berkwood’s results are very promising, and

compare favourably with similar published industry information, including projects that have been
subject to substantial process optimisation.

The results presented in this News Release provide the Berkwood Management with the
confidence to continue to drive the Lac Gueret Extension project forward with increased focus and
dedication. The Company anticipates receiving grade assay results from its Phase 4 drill program
(completed late December 2018) in the course of Q1, 2019 ( refer News Release of Jan. 16, 2018
