Commerce Resources Corp. Provides Update on the Metallurgical Test
Program at Université Laval for the Ashram Rare Earth Deposit
August 20, 2018 - Commerce Resources Corp. (TSXv: CCE, FSE: D7H) (the “Company” or
“Commerce”) is pleased to provide an update on the metallurgical test program for the Ashram
Rare Earth Deposit that is being completed under the direction of the Université Laval (“Laval”).
The test program uses an alternative flowsheet approach with the purpose of validating a
software model simulator developed by Laval (see news releases dated May 31 and July 24,
2018). The program is fully funded through a grant received by Laval with testwork being
completed in collaboration with SGS Canada Inc. (“SGS”) at their facilities.
Since the program was first initiated in May 2018, the test work has advanced aggressively with
a bench-scale level demonstration of the entire flowsheet now complete, including the
production of several grams of mixed rare earth oxide concentrate (see news release dated July
24, 2018). The Company is now pleased to report that the crushing and grinding component, as
well as the large-scale flotation component of the program, have now been completed. A total of
~1.5 tonnes of Ashram Deposit material was processed, with the flotation component completed
using individual batches ranging from 10 kg to 30 kg. Initial results are in line with expectations
with the team now looking ahead to the pilot-level hydrometallurgical component that will
commence with a caustic crack on an estimated 150 kg of flotation concentrate.
Company President Chris Grove states, “ We continue to be impressed with the rapid
advancement of this collaboration and look forward to the commencement of the
hydrometallurgical pilot component.”
The next steps of the program will use the flotation concentrate as feed to a semi-continuous
hydrometallurgical pilot operation to produce a purified solution containing the REE. The REE
solution will then be processed through a continuous solvent extraction (SX) separation pilot
circuit to separate the LRE (1) from the SEG (2) and HRE (3). In parallel, the solution composition
will be used to simulate the pilot scale SX separation circuit using the model simulator. The
comparison between the results of the pilot plant and the simulation will validate the model
simulator, which could then be used to further assess the economics of the separation of the REE
into individual rare earth oxides.
(1) LRE – Light Rare Earth
(2) SEG – Samarium, Gadolinium, Europium
(3) HRE – Heavy Rare Earth

Forward Looking Statements
This news release contains forward-looking information which is subject to a variety of risks and uncertainties and
other factors that could cause actual events or results to differ from those projected in the forward-looking
statements. Forward looking statements in this press release include, but are not limited to, potential process
methods and mineral recoveries assumption based on limited test work and by comparison to what are considered
analogous deposits that with further test work may not be comparable; the availability of labour, equipment and
markets for the products produced; and despite the current expected potential of the project, conditions changing
such that the minerals on our property cannot be economically mined, or that the required permits to build and
operate the envisaged mine can be obtained. The forward-looking information contained herein is given as of the
date hereof and the Company assumes no responsibility to update or revise such information to reflect new events or
circumstances, except as required by law.
