ASX Release 18 October 2023

==> picture [596 x 121] intentionally omitted <==

Rare Earths beneficiation testwork delivers strong TREO upgrades, providing further confidence in Cummins Range product strategy Test work delivers 20x TREO upgrade to concentrate, with favourable flotation characteristics which extrapolate well to the upgrade of leach residue.

Highlights

  • Cummins Range product strategy is focused on achieving the sale of a combined mineral concentrate to an off-taker for treatment via a dilute acid leach to extract LFP battery-grade phosphate and EV magnetgrade rare earths[1] .

  • Design of the proposed treatment process has focused on the ability to leach a clean apatite from the combined mineral concentrate, and the subsequent beneficiation of the leach residue to deliver a rare earth concentrate .

  • Recent tests at Baotou Mengrong Fine Materials (BTMR) have demonstrated a 20x upgrade of total rare earth oxides ( TREO) from 1% head-grade material with flotation recoveries of up to 49%. The upgrade factor achieved is in line with other developing RE deposits of similar head grades.

  • RareX believes that these results demonstrate the potential to further upgrade the leach residue (which is expected to have a 6% TREO grade) to even higher TREO concentrations.

  • Ore feed material, containing apatite, was used in the testing to determine the flotation configuration and reagent selection. Leach residue, which will be stripped of apatite, is expected to perform well with this flotation regime . Residue samples will be sent for confirmation testing once bulk flotation and leach trials are complete.

  • Recent apatite leach testwork[2] points toward the suitability of the Cummins Range combined mineral concentrate to produce a high purity phosphoric acid as a feedstock for the growing LFP battery sector .

RareX Limited (ASX: REE) ( RareX or the Company ) is pleased to advise that recent beneficiation testwork has returned promising results for the beneficiation of rare earths ( RE ) from its 100%-owned Cummins Range Rare Earths & Phosphate Project, located in the Kimberley region of Western Australia.

The current testwork program is focused on producing product and product derivative samples for offtake negotiations, as well as building data for the processing pathway for Cummins Range ore to deliver both highgrade phosphoric acid suitable for use in lithium-iron-phosphate ( LFP ) batteries and RE concentrates suitable for use in EV magnets.

RareX CEO James Durrant commented: “ We consider these results to be very encouraging.

“While these tests were undertaken on run-of-mine ore – which is not our proposed development pathway for Cummins Range – the run-of-mine ( ROM ) results will directly inform the flotation regime requirements for the RE leach residue after we’ve stripped away the pure apatite and fed it into the LFP supply chain.

“The fact that the tested processing regime can concentrate rare earths in ROM material by 20-fold has exceeded the expectations of our metallurgists. Importantly, this metallurgical approach is also directly applicable to the leach residue material, which has already been chemically upgraded to six times the original TREO head grade and has less mineralogical complexity – meaning it should deliver even better float performance with higher recoveries.

“The results provide continued support to the proposed Cummins Range product strategy[3] for the processing of the Stage 2 combined monazite-apatite phosphate concentrate.

“Our met team is now assembling product samples, both to ensure that we understand process performance for our and our offtakers’ facilities and also to provide real product sample and derivative product materials in support of ongoing offtake negotiations.”

RareX is proposing to use dilute phosphoric acid leaching to extract phosphate from the ore, leaving RE contained within a leach residue. This process step is proposed at the offtaker’s phosphoric acid facility as described in the recently released product strategy update[3] and the proposed installation is shown in Figure 1.

These latest tests were designed to help define the flotation regime requirements for RE beneficiation, with these initial tests undertaken on typical ROM ore samples from Cummins Range.

BTMR RE Beneficiation

RareX has initiated a beneficiation program at Baotou Mengrong Fine Materials ( BTMR ) in China to test RE beneficiation from both whole ore and the leach residue from the phosphoric acid production. BTMR is a highly experienced Chinese research institute and is a preeminent testing laboratory for rare earths beneficiation, particularly flotation.

This testwork is being undertaken on samples, which is expected to be typical of run-of-mine material from the Cummins Range deposit, in order to provide the required volume of material needed to test alternative float regimes. The composite tested in this program was prepared using ore intervals from both the Rare Dyke and Phos Dyke of the Cummins Range deposit, which were crushed and homogenised by Auralia Metallurgy before splitting the 50kg sample for BTMR tests.

A range of tests have been performed on this sample to determine the flotation configuration and reagent selection for the beneficiation of RE minerals. A summary of several of the recent flotation results is shown in Table 1.

Table 1: RE Flotation Results Summary

Test No. Calculated Head
%
Final Concentrate
TREO Grade % TREO Recovery % Mass Yield %
Test 23 1.14 22.04 32.81 1.69
Test 25 1.06 21.57 44.73 2.19
Test 43 1.01 22.50 48.74 2.20

Note: Test results were validated at the Analysis Centre of Baotou Institute of Rare Earth which is an accredited laboratory in China and the results showed good alignments for the final concentrate confirming accuracy of the results.

In the best result, a RE concentrate of 22.5% TREO grade was achieved from a feed grade of 1% at a remarkable recovery of 48.74%. To be able to achieve an upgrade of over 20x into concentrate from the ROM feed is considered to be very encouraging. These results are far better than results obtained in earlier testwork and the upgrade factor is also in line with other developing rare earth deposits of similar head grades.

Although the tests were not performed on the leach residue, the results provide further confidence in the viability of the proposed RE beneficiation process for the leach residue. Further tests will be undertaken with BTMR once the leach residue, currently being prepared at Perth laboratories, is ready to be dispatched.

According to previous testwork results[2] , it is believed that the leach residue (i.e., post apatite leach) will be enriched with monazite and therefore will contain residual apatite. REE metallurgists consider that it’s possible that this could provide further upside to the RE beneficiation process. Given the positive BTMR results, it is believed that the leach residue (which is expected to grade 6% TREO), could be upgraded materially to grades suitable for a typical RE refinery.

Next Steps

Further testwork is to be undertaken to replicate and improve on these results following these positive results with results expected within the coming months. The Company is also working toward the production of mineral concentrate and product derivatives (leach liquor and RE residue) samples to advance offtake discussions and refine process design criteria.

In addition to the upcoming testwork, results of the 2023 drill program are expected to be available soon which will be used support another update of the Mineral Resource Estimate for Cummins Range.

In cases where ‘industry standard’ work
has been done this would be relatively
simple (e.g., ‘reverse circulation drilling
was used to obtain 1m samples from
which 3 kg was pulverised to produce a
30 g charge for fire assay’). In other
cases, more explanation may be
required, such as where there is coarse
gold that has inherent sampling
problems. Unusual commodities or
mineralisation types (e.g., submarine
nodules) may warrant disclosure of
detailed information.
• Sample interval selection for the metallurgical
testwork was based on geological controls
and mineralisation of the deposit, the
samples were considered representative of
the mineralisation that were intended to be
tested.
Drilling techniques • Drill type (e.g., core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details
(e.g., core diameter, triple or standard
tube, depth of diamond tails, face-
sampling bit or other type, whether core
is oriented and if so, by what method,
etc).
• Drilling techniques used for the Cummins
Range samples used for the metallurgical
testwork were:
o
Reverse Circulation (RC) drilling in 2020-
2021, 2022 using 5 ½ inch diameter
hammer.
o
Diamond drilling in 2021- 2022 using HQ

• Larger and more capable rigs were used for
collection of the metallurgical samples which
allowed for good recoveries of samples.
During each drill program, all drill rigs were
checked by professional geologists, and all
drill holes were logged and monitored for
recoveries and accuracy prior to sample
splitting and logging.
• Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
preferential loss/gain of fine/coarse

• Holes used for the metallurgical testwork had
good sample recovery hence minor sample
bias. There is no distinctive relationship exist
between sample recovery and grade.
Logging • Whether core and chip samples have
been geologically and geotechnically
logged to a level of detail to support
appropriate Mineral Resource
estimation, mining studies and
metallurgical studies.
• All samples used for the metallurgical
testwork were geologically logged to a detail
level that supported the metallurgical studies.

Geology • Deposit type, geological setting and
style of mineralisation.
• The Cummins Range REO deposit occurs within
the Cummins Range carbonatite complex
which is a 2.0 km diameter near-vertical
diatreme pipe that has been deeply weathered
but essentially outcropping with only thin
aeolian sand cover in places. The diatreme pipe
consists of various mafic to ultramafic rocks
with later carbonatite intrusions. The primary
ultramafic and carbonatite rocks host low to
high-grade rare-earth elements with
background levels of 1000-2000 ppm TREO
and high-grade zones up to 20% TREO.
Disseminated apatite is through all rock types
and is also contained in phoscorite. Above the
carbonatite dykes is a well-developed regolith
profile that extends to 100 m below the surface
where a combination of residual, or eluvial and
chemical weathering have redistributed and
upgraded rare earths and phosphate.
• QEMSCAN and MicroXRF results have showed
that all the phosphate is contained in Apatite
and Monazite. The Apatite contains low UTh,
no cadmium and chlorine, and elevated levels
of Fl that are well below acceptable limits.
• QEMSCAN and MicoXRF have showed the REO
in the Regolith are deporting mostly to
monazite, with lesser amounts deporting to
bastnaesite, crandallite, and REE intergrowths.
• QEMSCAN and MicoXRF indicate the REO in
the fresh rock are deporting to monazite,
bastnaesite, parisite and REE intergrowths.

Criteria JORC Code explanation Commentary
Balanced
reporting
• Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low
and high grades and/or widths should
be practiced avoiding misleading
reporting of Exploration Results.
• N/A
Other substantive
exploration data
• Other exploration data, if meaningful
and material, should be reported
including (but not limited to):
geological observations; geophysical
survey results; geochemical survey
results; bulk samples – size and
method of treatment; metallurgical
test results; bulk density, groundwater,
geotechnical and rock characteristics;
potential deleterious or contaminating
substances.
• This report includes meaningful metallurgical
results where rare earth flotation tests was
performed on a regolith composite containing
1% TREO and showed:
o Test 23
 22.04% TREO grade
 32.81% TREO recovery
o Test 25
 21.57% TREO grade
 44.73% TREO recovery
o Test 43
 22.50% TREO grade
 48.74% TREO recovery
Further work • The nature and scale of planned
further work (e.g. tests for lateral
extensions or depth extensions or
large-scale step-out drilling).
• Diagrams clearly highlighting the areas
of possible extensions, including the
main geological interpretations and
future drilling areas, provided this
information is not commercially
sensitive.
• Scoping Study for the Stage 1 DSO and Stage 2
operations is in progress, with completion
expected end of July 2023.
• Baseline Environmental studies have
commenced with the instalment of 14 water
monitoring bores in 2022.
