ADDITIONAL HIGH-GRADE PRIMARY MINERALISED
ZONES DISCOVERED AT CUMMINS RANGE AS
RAREX GEARS UP FOR MAJOR NEW DRILLING PUSH
Latest assays return the deepest intercept to date of 21.9m at 1.7% TREO 1 including 6.4m at
3.5% TREO
HIGHLIGHTS
•
Further significant assay results received from 2021 drilling program at the Cummins Range
Rare Earths Project in the Kimberley region of WA
•
Another deep high-grade zone discovered in hole CDX0018, which intersected:
- 21.9m at 1.7% TREO, including 6.4m at 3.5% TREO
•
Further strong silver assays returned in hole CDX0017
- 5.9m at 1.5% TREO and 222g/t Ag
•
CDX0019 assayed 27m at 1.81% TREO including 5.6m at 4.81% TREO
•
Results support the recently announced Exploration Target for the primary zone
•
Major new resource expansion drilling program set to commence in 2-3 weeks
RareX Limited (ASX: REE) (RareX or the Company) is pleased to report further significant assay results from
the 2021 diamond drilling campaign at its 100%-owned Cummins Range Rare Earths Project in the
Kimberley region of Western Australia.
The latest results provide further confidence in the recently announced Exploration Target for the Project
and highlight the outstanding potential to expand the existing JORC Indicated and Inferred Mineral
Resource 2 of 18.8Mt at 1.15% TREO + 0.14% Nb2O5.
Assays have been received for the diamond portion of holes CDX0017, CDX0018 and CDX0019.
CDX0018 intersected multiple mineralised zones, including a newly discovered deeper zone from 275m
down-hole with an intercept of 21.9m at 1.7% TREO including 6.4m at 3.5% TREO, as shown in Figure 2.
This zone is open in all directions including up-dip.
The assays returned for this intersection have a low phosphate content likely indicating the presence of
bastnasite (rare earth carbonate) which is an easily processed form of rare earths around the world such
as Mountain Pass in California. Micro XRF work is currently being undertaken to confirm this at Portable
Analytical Solutions in Perth.

Hole CDX0017 is a re-drill of hole CDX0002, which was lost at 135m (assays for which were announced to
ASX on 22 November 2022).
CDX0017 intersected significant silver in the main fault zone with 5.9m at 1.5% TREO and 222 g/t Ag. Hole
CDX0017 is located 40m south-east of hole CDX0012, which also intersected high-grade silver (ASX: 18
January 2022).
The silver potential is still being assessed by the RareX geological team.
CDX0019 also intersected significant primary mineralisation back in the main breccia zone of 27m at 1.81%
TREO including 5.6m at 4.81% TREO.

RareX has now received results from all the diamond holes from the 2021 program with the only
outstanding assays being from the RC program.
Drilling for 2022 is set to commence in April.
RareX Managing Director, Jeremy Robinson, said: “The final batch of assays from the diamond drilling have
been received, and they continue to support the huge growth potential in the primary zone, with new zones
continuing to be discovered at depth. This gives us great confidence in the outlook for Cummins Range as
we prepare to embark on the next major phase of resource expansion drilling, commencing in 2-3 weeks.
“This next phase of exploration will be designed to convert the Exploration Target into JORC Resources and
to elevate the Project into what we believe it represents – a top-3 rare earths deposit in Australia and one
of the largest and most significant new development assets globally. We will provide further information
on the upcoming drill program in the near future.”
This announcement has been authorised for release by the Board of RareX Limited.

Appendix 3: JORC Code 2012 Edition – Table 1
JORC Code, 2012 Edition – Table 1
Cummins Range Section 1 Sampling Techniques and Data
Criteria
JORC Code Explanation
Sampling
techniques
Nature and quality of sampling (eg 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.
Include reference to measures taken to ensure sample representivity and the appropriate
calibration of any measurement tools or systems used.
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 (eg
‘reverse circulation drilling was used to obtain 1 m 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 (eg submarine nodules) may warrant disclosure of detailed
information.
Drilling
Techniques
Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (eg 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).
Drill Sample
Recovery
Method of recording and assessing core and chip sample recoveries and results assessed.
Measures taken to maximise sample recovery and ensure representative nature of the
samples.

The Cummins Range Rare Earth deposit is being drilled tested with RC drilling
and diamond drilling.
The RC drill rig used a 5 ½ inch diameter hammer. Each 1m bulk sample was
collected in a plastic bag.
Diamond drill sizes used are PQ, HQ and NQ2
Each metre was analysed with a portable XRF, and recovery and geology logs
were completed.
Sample interval selection was based on geological controls and mineralisation
Each 1m RC bulk sample was split with a riffle splitter to the appropriate size.
Samples varied in length from 1m to 4m.
Each core sample was cut in half with a brick saw. The half core sample was
sent to the laboratory with intervals ranging from 0.3m to 1.3m.
Samples were assayed for 42 elements using either a peroxide fusion with a
ICP-OES and ICP-MS finish, or a four acid digest with a ICP-OES and ICP-MS
finish
Prefix CRX drill holes are reverse circulation (RC) drilling
Prefix CDX are diamond drilling. 11 of the diamond drill holes were started
with an RC precollar ranging from 40-90m depth. Holes were then continued
with HQ3 or NQ2 diamond core
5 diamond drill holes were drilled core from surface.
Recoveries for all drill holes were recorded for each metre. Recoveries for
each hole in this announcement are CDX0017 90%, CDX0018 99%, CDX0019
97%

Whether a relationship exists between sample recovery and grade and whether sample bias
may have occurred due to preferential loss/gain of fine/coarse material.
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 metres drilled had a geology log completed. Geology logs were aided using
geochemical analysis from a portable XRF.
The detail of logging is appropriated for Mineral Resource estimation.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc)
photography.
The total length and percentage of the relevant intersections logged.
Subsampling
techniques
and sample
preparation
If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation
technique.
•
•
•
Quality control procedures adopted for all sub-sampling stages to maximise representivity
of samples.
Splits from the drill rig were not used. The entire 1m bulk sample was split
with a riffle splitter to the appropriate size. Samples varied in length from 1m
to 4m.
This RC sampling technique is better than industry standards and is
appropriate for this style of mineralisation and for resource estimation.
Diamond core was cut in half with a brick saw and half the core was sent to
the laboratory. This is an appropriate method for this style of mineralisation
and for resource estimation.
Measures taken to ensure that the sampling is representative of the in situ material
collected, including for instance results for field duplicate/second-half sampling.
Whether sample sizes are appropriate to the grain size of the material being sampled.
Quality of
assay data
and
laboratory
tests
The nature, quality and appropriateness of the assaying and laboratory procedures used
and whether the technique is considered partial or total

Quality and adequacy of topographic control.
Data
spacing and
distribution
Data spacing for reporting of Exploration Results.
•
Whether the data spacing and distribution is sufficient to establish the degree of geological
and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation
procedure(s) and classifications applied.
•
Drill hole collars were located by handheld GPS
All coordinates are in MGA Zone 52H 1994
Topographic control is maintained by the use of previously surveyed drill
holes. The Cummins Range deposit is located on flat terrain.
Down hole surveys were taken every 30m, using a digital Reflex multi shot
camera.
The purposed of the drill program is to test for primary mineralisation below
the regolith. Drill spacing of 40m on 80m drill lines is appropriate to establish
geological and grade continuity.
2m to 4m RC composites were completed in areas where higher grades were
not expected
Whether sample compositing has been applied.
Orientation
of data in
relation to
geological
structure
Whether the orientation of sampling achieves unbiased sampling of possible structures and
the extent to which this is known, considering the deposit type.
•
The angled drill holes were directed as best as possible across the known
geology.
If the relationship between the drilling orientation and the orientation of key mineralised
structures is considered to have introduced a sampling bias, this should be assessed and
reported if material.

JORC Code Explanation
Mineral
tenement and
land
tenure
status
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 REO 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 has purchased the tenement from Element
25 with a potential capped royalty payment of $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.
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 back
ground levels of 1000-2000ppm TREO and high grade zones up to 17% TREO.
The current resource sits primarily within the oxidised/weathered zone which
reaches to 120m below the surface. Metallurgical studies by previous
explorers and by RareX show the rare earth elements are hosted by Monazite
which is a common and favourable host for rare earth elements.
All drill hole locations are shown on the drill plan and collar details are tabled
within the announcement
The security of the tenure held at the time of reporting along with any known
impediments to obtaining a licence to operate in the area.

If the exclusion of this information is justified on the basis that the information is not
Material and this exclusion does not detract from the understanding of the report, the
Competent Person should clearly explain why this is the case.
Data
aggregation
methods
In reporting Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (eg cutting of high grades) and cut-off grades are usually
Material and should be stated.
•
•
Where aggregate intercepts incorporate short lengths of high grade results and longer
lengths of low grade results, the procedure used for such aggregation should be stated
and some typical examples of such aggregations should be shown in detail.
•
Significant intercepts were calculated using weighted averaging
A lower cut off of 0.5% TREO was used with a maximum of 3m dilution. This
cut off grade and dilution is thought to be appropriate due to likely open cut
mining methods that would be used on the outcropping ore body.
No metal equivalent values have been used
The assumptions used for any reporting of metal equivalent values should be clearly
stated.
Relationship
between
mineralisation
widths
and
intercept
lengths
These relationships are particularly important in the reporting of Exploration Results
•
If the geometry of the mineralisation with respect to the drill hole angle is known, its
nature should be reported.
•
The angled drill holes were directed as best as possible across the known
geology.
The true width of the intercepts in this announcement are >80% of the down
hole lengths
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’).

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.
•
Sections, a drill hole plan and a vertical longitudinal projection are with in the
announcement.
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
to avoid misleading reporting of Exploration Results.
•
Reporting is considered balanced
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.
