Kelowna,
BC -- January 12, 2018 -- InvestorsHub NewsWire -- Enertopia
Corporation (ENRT)
on the OTCQB and (TOP)
on the CSE (the "Company" or "Enertopia") is pleased to
announce the following synthetic brine testing update for the
recovery of Lithium and ultimately, upgrading the Lithium to
battery grade Li2CO3 by our technology partner Genesis Water
Technologies Inc., (GWT) a leader in specialized water treatment
solutions.
The goals of this much
larger independent third-party lab testing from the Company's
lithium project in Clayton Valley, NV were to test, in a precise
manner, the effect of varying pH in leach solutions used to create
synthetic brines by dissolution of lithium from source rock from
the Company's Clayton Valley, NV project. The synthetic lithium
brines were created by using one (1) part lithium bearing source
rock (500g) to four (4) parts solution (2000ml) as a baseline for
our upcoming bench testing of the synthetic brines through the GWT
ENERLET system. These solutions had the following pH values, 2.0
and 5.5 (using H2SO4), and pH of 11.0 (using
NaOH).
Also
the synthetic brine solutions were
tested over periods from 2hrs to 48hrs to test how much lithium and
other minerals would be liberated into solution over the tested
time intervals.
Overview of 3rd party
laboratory results from the synthetic brine sample results are
outlined below:

KEY FINDINGS:
Synthetic lithium brine
solution produced from leaching of bulk sample GWT002 by alkaline
leaching (with a pH of 11) returned the best results with 99.99% of
magnesium being left out of the produced synthetic lithium brine
solution.
Separation of magnesium
from lithium in brines used to produce a lithium carbonate product
is a critical process factor, as well as cost
factor,
in the production of battery grade lithium carbonate. The finding
that magnesium can be easily suppressed in the production of
synthetic lithium brine from the source rock at the Clayton Valley
Project bodes well for cost containment in, as well as purity of
lithium carbonate product from, the ENERLET
proposed recovery
process.
Lithium values of 170 ppm
and only 3 ppm Mg in
solution were found in
synthetic lithium brine produced by alkaline leach from bulk sample
GWT-002. For comparison the disclosed inferred brine resource of
one of the properties in Clayton Valley, NV has an average Lithium
grade of 123 ppm and over 200 ppm Magnesium, requiring additional
cost (to separate magnesium) to produce an acceptable lithium
carbonate product. Thus, our test synthetic lithium brine, produced
by alkaline leach of our source rock, returned values 38.21% higher
in lithium and contains only 0.015% Mg based on
comparison.
The above lithium values of 170 ppm are also more than 100% above
several reported petro
lithium projects. Brines
from those petro
lithium
projects are
also reported to feature
high levels of magnesium that must be removed to produce an
acceptable lithium carbonate product.
There was no significant
difference in the amount of dissolved lithium into
solution
based on a
two
hour solution test or the
prolonged forty-eight hour solution test period. This indicates the
Lithium readily dissolves out of the source rock in a very short
period of time, thus allowing for rapid processing time to
synthetic lithium brine.
Lithium in solution was
computed to be over 40% of Lithium in the source rock. This
indicates the opportunity for a substantial increase in the Lithium
in solution grade, using a more concentrated solution and or
industry standard separation technologies going
forward.
NEXT
STEPS:
The Company continues to
work aggressively at unlocking the value of the
lithium
bearing rock at
surface
along the uplifted block
along the eastern flank at Clayton Valley, NV. Further testing of
lithium source rock and pH controlled liquid ratios will continue
along with and in combination with testing of other separation
methods that will be ongoing over the first quarter of 2018. The
Company will also have a booth at the Prospectors and Developers
Association of Canada (PDAC) this year from March 4-7 in Toronto,
ON. Modern technology is changing the face of mining.
For example
drones can now be used
quickly and inexpensively to map and digitize a property in hours
as opposed to weeks or months in the past. Autonomous mining
vehicles now have production rates 40% higher and no lost time
accidents than those of conventional mining
vehicles.
"We look forward to the
results from our Bench Test partner GWT and using the latest proven
mining methods in creating shareholder value." Stated CEO Robert
McAllister
