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.

| 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: oReverse Circulation (RC) drilling in 2020-2021, 2022 using 5 ½ inch diameter hammer. oDiamond 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. |

• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. |
• The Cummins Range deposit is located on tenement E80/5092 and is 100% owned by Cummins Range Pty Ltd which is a wholly owned subsidiary of RareX Ltd. Cummins Range Pty Ltd purchased the tenement from Element 25 with a potential capped royalty payment of AU$1m should a positive PFS be completed within 36 months of purchase finalisation. |

• CRA Exploration defined REO mineralisation at Cummins Range in 1978 using predominantly aircore drilling. Navigator Resources progressed this discovery with additional drilling after purchasing the tenement in 2006. Navigator announced a resource estimate in 2008. Kimberly Rare Earths drilled additional holes and upgraded the resource estimate in 2012. |
| 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 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. |

• 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 monaziteo ~85% monazite was well liberated or as high grademiddlings |
| 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. |
