Commerce Resources Announces Significant Advancements and Simplification of the Ashram Deposit’s Process Flowsheet
Commerce Resources Announces Significant Advancements and
Simplification of the Ashram Deposit’s Process Flowsheet
March 4, 2024 – Commerce Resources Corp. (TSXv: CCE, FSE: D7H0, OTCQX: CMRZF )
(the “Company” or “Commerce”) is pleased to announce that it has made significant advancements
in the mineral processing and hydrometallurgical flowsheets for the Ashram Rare Earth and
Fluorspar Deposit (the “Ashram Deposit”). The Ashram Deposit, wholly owned by the Company
and located in Quebec, Canada, is one of the largest undeveloped monazite dominant rare earth
deposits in the world. This rare earth mineralogy results in significant NdPr distributions (>20%).
The Company is pleased to report a significant simplification and optimization of the Ashram
Deposit’s front-end mineral processing flowsheet whereby 30-35+% REO monazite mineral
concentrates at strong recovery (between 60 -70%) are produced using only flotation . This
testwork has been completed at bench scale , is demonstrated repeatable, and has been scaled up
successfully from ~1 kg to 10 kg floats using conventional mechanical flotation cells. The recent
testwork, which uses readily available reagents, has been carried out by SGS Canada in Lakefield,
Ontario (“SGS”), and builds upon the beneficiation testwork carried out by CanmetMINING, a
branch of Natural Resources Canada (NRCan) (see news release dated May 13, 2020). This new
flowsheet is a significant simplification , with comparable performance, to the prior flotation -
leach-magnetic separation flowsheet. The recent results represent some of the best grade/recovery
performance for bench scale tests on material from the Ashram Deposit. Further optimization
testing is pending, including Locked -Cycle Testing (LCT) to confirm closed circuit recoveries ,
and variability testing on nine (9) samples prepared from drill core spatially distributed throughout
the deposit.
In addition to the mineral processing developments , a streamlined hydrometallurgical flowsheet
has also been developed and demonstrated at bench scale for the downstream processing of the
monazite flotation concentrate produced by SGS . The hydrometallurgical flowsheet uses a
standard acid bake – water leach process followed by thorium removal and direct rare earth
element (“REE”) precipitation (Figure 1) . This downstream testwork has been carried out by
Trois-Rivieres-based L3 Process Development (“L3”).
Company President Chris Grove states “We are very excited by these results confirming our
expectations of positive beneficiation from our Ashram Deposit with its very attractive mineralogy
and geology. We look forward to announcing additional developments as we continue to advance
this excellent asset.”
This streamlined hydrometallurgical flowsheet developed and demonstrated by L3 on the SGS
monazite concentrates achieved an overall recovery into solution for NdPr above 95% and TbDy
above 82% while significantly reducing sulfuric acid consumption . The t horium was fully
removed from the water leach solution using a three-stage solvent extraction process. The REEs
were then precipitated using oxalic acid and converted to carbonates using a 1 -step metathesis
process, achieving an overall recovery (deposit material to marketable mixed rare earth elements
product) of over 62% NdPr. In addition to the oxalate and carbonate REE precipitate s, t he
downstream flowsheet is amenable to producing a mixed rare earth oxide (“mixed REO”), thereby
providing significant flexibility in end-user offtake preferences and shipping optimization.
The Ashram Deposit ranks as one of the largest REE deposits globally, consisting of a monazite
dominated, single mineralized body outcropping at surface, and has a footprint approximately
700 m along strike, over 300 m across, and 600 m deep, remaining open in several directions.
Therefore, the deposit is envisioned to be an open -pit extraction operation at production, with a
very low strip ratio. Coupled a monazite rare earth mineralogy and strong NdPr distributions, these
attributes allow for the company to have significant flexibility in flowsheet design, whereby a
60+% overall recovery of the NdPr into saleable product is significant . The new mineral
processing flowsheet will permit an operator to leverage the size of the deposit and optimize
mining for effective recovery into a high -grade monazite concentrate in order to significantly
simplify and thereby reduce project mineral process ing and downstream hydromet CAPEX and
OPEX.

About the Ashram Deposit
The Ashram Deposit ranks as one of the largest REE (and fluorspar) deposits globally, consisting
of a monazite dominated, single mineralized body outcropping at surface, and has a footprint
approximately 700 m along strike, over 300 m across, and 600 m deep, remaining open in several
directions. The deposit hosts a measured resource of 1.6 million tonnes ( Mt) at 1.77% rare earth
oxide (REO) and 3.8% F, an indicated resource of 27.7 Mt at 1.90% REO and 2.9% F, and an
inferred resource of 219.8 Mt at 1.88% REO and 2.2% F, at a cut -off grade of 1.25% REO
(Effective Date July 5 th, 2012). Note, mineral resources are not mineral reserves as they do not
have demonstrated economic viability. There is no certainty that all or any part of the Mineral
Resources will be converted into Mineral Reserves.

About Commerce Resources Corp.
Commerce Resources Corp. is a junior mineral resource company focused on the development of
the Ashram Rare Earth and Fluorspar Deposit located in Quebec, Canada. The Company is
positioned to become one of the lowest cost rare earth producers globally, with a specific focus on
being a long-term supplier of mixed rare earth carbonate and/or NdPr oxide to the global market.
The Ashram Deposit is characterized by simple rare earth (monazite, bastnaesite, xenotime) and
gangue (carbonates) mineralogy, a large to nnage resource at favourable grade, and has
demonstrated the production of high -grade (>45% REO) mineral concentrates at high recovery
(>70%) in line with active global producers. In addition to being one of the largest rare earth
deposits globally, Ashram is also one of the largest fluorspar deposits globally and has the potential
to be a long-term supplier to the met-spar and acid-spar markets.

developments that the Company believes, expects or anticipates will or may occur in the future. Forward looking
statements in this news releas e include that that mixed REC is readily saleable; that partial separation of REEs will
allow for the marketability of individual elements to be produced; that Ashram has the potential to become one of the
largest fluorspar deposit and a long -term supplier to the met -spar and acid -spar markets; and that the Company is
positioning to be one of the lowest cost rare earth element producers globally. These forward -looking statements are
subject 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 events,
activities or developments from coming to fruition include: that we may not be able to fully finance any additional
exploration on the Ashram Project; that even if we are able raise capital, costs for exploration activities may increase
such that we may not have sufficient funds to pay for such exploration or processing activities; the timing and content
of any future work programs; geological interpretations based on drilling that may change with more detailed
information; potential process methods and mineral recoveries ass umptions 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 or samples derived from the Ashram Project may not yield positive results, and
even if such tests are successful or initial sample results are positive, the economic and other outcomes may not be as
expected; the availability of labour and equipment to undertake future exploration work and testing activities;
geopolitical risks which may result in market and economic instability; and despite the current expected viability of
the Ashram Project, conditions changing such that even if metals or minerals are discovered on the Ashram Project,
the project may not be commercially viable; The forward-looking statements contained in this news release are made
as of the date hereof and the Company assumes no responsibility to update or revise such information to reflect new
