Testwork Confirms Favourable Mineralogy for Rare Earths Beneficiation Rare earths enriched residue mineralogical testwork further supports the Cummins Range Product Strategy[1 ]

Highlights

  • Recent mineralogical testwork further supports RareX’s proposed product strategy[1 ] for the Cummins Range Project , focused on the sale of a combined apatite and monazite mineral concentrate to an existing phosphoric acid production plant for apatite leaching and further upgrade of the rare earths (RE) enriched leach residue by flotation.

  • The testwork comprised Quantitative Evaluation of Materials by Scanning Electron Microscopy (QEMSCAN) performed on a leach residue sample to confirm the RE mineralogy.

  • Results showed favourable leach residue mineralogy, post apatite removal, supporting the RE beneficiation step of the proposed product strategy[1] .

  • Monazite identified to be the main RE-bearing mineral, accounting for ~70% of the total rare earths in the leach residue.

  • Mineralogy of leach residue shown to be similar to the initial head sample, suggesting the RE minerals remain intact during the dilute acid leach step. The acid leaching also improved the monazite liberation according to the mineralogy results.

  • The same head sample was tested at Baotou Mengrong Fine Materials[2] (BTMR), with excellent upgrade results (>20x RE upgrade). The improved RE grade, distribution and liberation of the leach residue should yield similar or better flotation results.

  • Bulk float underway to prepare samples for additional apatite leaching and leach residue RE beneficiation.

RareX Limited (ASX: REE – RareX or the Company ) is pleased to advise that recent mineralogy analysis on a leach residue sample from the 100%-owned Cummins Range Rare Earths and Phosphate Project (the Project , Cummins Range ), located in the Kimberley region of Western Australia, has shown positive results, confirming positive mineralogy for rare earths beneficiation.

The Cummins Range Project will produce a dual mineral concentrate that will contain high purity apatite and NdPr-rich monazite. Following the completion of recent positive testwork[2,3] , RareX has proposed a product

strategy whereby the mineral concentrate from Cummins Range will first be treated at an existing phosphoric acid production plant to extract the apatite. This will be followed by the onward sale of the leach residue, containing elevated RE grades, which can be further upgraded via simple flotation. The positive mineralogy results of the leach residue outlined in this announcement further support this proposed product strategy and the hypothesis that a saleable RE concentrate (>30% TREO grade) can be produced from the leach residue.

RareX Chief Executive Officer, James Durrant, said: “These latest mineralogical and metallurgical results continue to support our product strategy for the Cummins Range Project. These results are very encouraging and are highly suggestive of excellent flotation performance of the leach residue, which will be the next phase of our testwork program. This positive news comes on the back of the fantastic flotation performance achieved on similar mineralogical samples, where a twenty-times upgrade was achieved, and follows very positive apatite leach results. Collectively, our metallurgical testwork to date shows we are well on the path to being able to provide battery-grade apatite phosphate and magnet-grade monazite rare earths to a strategic offtaker. ”

Leach Residue Mineralogy Analysis

Following the positive dilute acid leach and RE flotation results at BTMR, the next important step of RareX’s metallurgical testwork program was to demonstrate good mineralogy of the leach residue to support the proposed product strategy. A Quantitative Evaluation of Materials by Scanning Electron Microscopy (QEMSCAN) analysis was performed at ALS Metallurgy to better understand the mineralogy of the leach residue and confirm favourable RE mineral distribution that will be used to support further RE beneficiation testwork.

The major RE deportment data and monazite liberations are shown in Figure 1 and Figure 2 respectively.

Figure 1. La, Ce, Nd and Pr element deportment to minerals

As indicated, monazite is the main RE hosting mineral, accounting for approximately ~70% of the total rare earth elements. Bastnasite (10%) and crandallite (20%) host the remaining RE. The RE deportment is very well aligned to the mineralogy analysis on the head sample that was used for generating this leach residue, suggesting that the RE minerals remained intact during the dilute phosphoric acid leaching process.

Figure 2. Combined monazite liberations

Monazite locking and liberation analysis showed minimal locking of monazite with other minerals post the dilute acid leach. Improved liberations were also observed, showing 64.4% ‘well liberated’ (at -53µm grind size) monazite (i.e., >90% monazite) and another 20.5% classified as ‘high grade middlings’ (60-90% monazite).

It should also be noted that this leach residue is generated from the same head sample that was tested at BTMR and achieved >20 times RE upgrade[2] . This result is well aligned to RareX expectations and further supports the proposed product processing strategy at the offtaker’s facility. The similar mineralogy and the improved RE mineral liberations provide further confidence to RareX that a >30% RE concentrate can be produced from the leach residue suitable for typical RE refineries.

Next Steps

RareX is currently 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. RE flotation will also be carried out on leach residues to confirm that similar, if not better, flotation upgrades can be achieved.

JORC Code, 2012 Edition – Table 1
Cummins Range Section 1 Sampling Techniques and Data
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (e.g., cut
channels, random chips, or specific
specialised industry standard measurement
tools appropriate to the minerals under
investigation, such as down hole gamma
sondes, or handheld XRF instruments, etc.).
These examples should not be taken as
limiting the broad meaning of sampling.
• Diamond drill cores and RC chips were sampled for the
metallurgical testwork. Samples were selected based
on drill assays, drill hole location and intervals,
geological and mineralogical data. Samples were riffle
split from bulk samples and sent to Auralia Metallurgy
Perth and/or BV Perth and/or ALS Perth and/or Nagrom
Perth for assays and further testwork.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
• For RC chips, the entire bulk samples were riffle split to
ensure a representative sample from the selected
interval. Quarter diamond drill cores were sent to
laboratories to conduct crushing, sampling and
assaying. All laboratories used in the assaying of the
Cummins Range material were checked for sampling
and assaying equipment and equipment calibrations /
accuracy.
• Aspects of the determination of
mineralisation that are Material to the Public
Report.
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 and PQ
sized rods.
Drill sample
recovery
• Method of recording and assessing core and
chip sample recoveries and results
assessed.
• Samples used for the metallurgical testwork were
collected by riffle split. Additional laboratory assays
were undertaken on the samples submitted for the
testwork and showed good alignments to the drill
assays.

• 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 mafc to ultramafc rocks with
later carbonatite intrusions. The primary ultramafc
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 profle 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.

JORC Code, 2012 Edition – Table 1
Cummins Range Section 2 Reporting of Exploration Results
Criteria JORC Code explanation Commentary
• If it is not known and only the down hole
lengths are reported, there should be a clear
statement to this effect (eg ‘down hole
length, true width not known’).
• Not applicable as no drilling reported.
Diagrams • Appropriate maps and sections (with scales)
and tabulations of intercepts should be
included for any significant discovery being
reported. These should include, but not be
limited to a plan view of drill hole collar
locations and appropriate sectional views.
• The report is relating to metallurgical beneficiation
testwork and no significant discovery is being
reported.
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.
• Not applicable as no drilling reported.
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 mineralogical analysis was performed on a
leach residue and showed favourable mineralogy that
supports further RE beneficiation:
o ~70% TREO in monazite
o ~85% monazite was well liberated or as high grade
middlings
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.
• Baseline Environmental studies have commenced with
the instalment of 14 water monitoring bores in 2022.
• Further apatite and monazite beneficiation and
refining testwork.
• Beneficiation plant pre-feasibility study.
• DSO feasibility study.
