Commerce Resources Corp. to Present at the 2020 CMP Conference on
Flotation Scale-up in REE Mineral Processing
January 7th, 2020– Commerce Resources Corp. (TSXv: CCE, FSE: D7H0) (the “Company” or
“Commerce”) is pleased to announce that, through its collaboration with its colleagues from
Université Laval (“Laval”), will be presenting a paper and oral presentation at the upcoming 52nd
Annual Canadian Mineral Processors Operators (“CMP”) conference to be held in Ottawa, ON,
January 21st to 23rd, 2020.
With respect to mineral processing flowsheet s for rare earth element (“REE”) projects , the
challenges of scale-up from bench level testing is rarely discussed in meaningful detail. However,
an understanding of the potential challenges is essential to effective scale -up for maintaining
performance and reagent consumption rates, while estimating capital and operating expenditures
accurately. Such challenges are not uncommon in the REE space ; however, these may be more
difficult for deposits with complicated or poorly understood rare earth mineralogy, thus
highlighting the need for academic/industry discussion and collaboration. Correspondingly, the
Ashram Deposit, with its simple rare earth and gangue mineralogy, and resultant well-understood
processing techniques, potentially presents a base case scenario for some issues, and therefore, the
test data generated by Laval has been used to formulate cautionary guidance for scale-up and large-
scale concentrate production , potentially applicable to all rare earth projects regardless of
mineralogy.
The paper is titled Challenges of Scale-Up in Grinding and Flotation of Rare Earth Minerals” and
will be published for global distribution in a CMP Proceedings volume following the conference.
The oral presentation will take place at 1:50 PM on January 23rd during the Flowsheet & Process
Control session. The paper and oral presentation outline a 2018-2019 case study documenting the
grinding and flotation testwork completed by Laval, at the lab/bench (1 kg) and larger (10-30 kg)
scale, on material from the Ashram Rare Earth and Fluorspar Deposit.
The lead author on the paper is Jean-François Boulanger, an Assistant Professor at the Université
du Québec en Abitibi-Témiscamingue (UQAT) in Rouyn-Noranda, and former PhD student with
Université Laval. Mr. Boulanger was the lead Project Manager on the Ashram metallurgical test
program completed at Laval in 2018-2019 (see news release dated August 1, 2019). Mr. Claude
Bazin, Professor and Project Supervisor at Laval, and Mr. Darren L. Smith, Ashram Project
Manager, are second and third authors, respectively.

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 s tatements in this press release include the presumption that the Ashram Deposit
potentially presents a base case scenario for some issues potentially applicable to all rare earth projects regardless
of minerology . These forward -looking statements are subj ect to a variety of risks and uncertainties and other
factors that could cause actual events or results to differ materially from those projected in the forward -looking
information. Risks that could change or prevent these statements from coming to fruitio n include changing costs
for mining and processing; increased capital costs; the timing and content of upcoming work programs and reports
produced on work done ; geological interpretations based on drilling that may change with more detailed
information; po tential 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; testing
of our process may not prove successful and even it tests are successful, the economic and other outcomes may
not be as expected; the availability of labour, equipment and markets for the products produced; and despite the
current expected viability 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.
