Safety
There were no recordable injuries reported during the quarter.
Ema REE Project
The EMA REE project is unique amongst Brazilian REE projects in that it shares almost identical
characteristics with the REE deposits developed over felsic volcanic rocks in the southwest of China, the
world´s largest known ionic clay rare earth region.
Ema Mineral Resource Estimate
A set of Inferred Mineral Resources was estimated for the contained rare earth elements in the Ema
project, constrained by different cut-off grades, by the consultancy group GE21 Consultoria Mineral Ltda
(GE21) and reported in accordance with the JORC Code (2012)1.

Geology and mineralisation
The REE mineralisation at Ema is contained within the tropical lateritic weathering profile developed on
top of felsic volcanic and volcaniclastic rocks (rhyolites and ignimbrites).
The REE mineralisation is concentrated in the weathered portion of the profile where it has dissolved
from primary rare earth minerals such as monazite and xenotime, migrating downwards through the
regolith profile where it is adsorbed on to the fine particles of aluminosilicate clays (e.g. kaolinite, illite,
smectite). This adsorbed REE is the target for extraction and production of the rare earth oxides.
SGS Brazil Metallurgical Test Work
Results of phase 2 ammonium sulphate extraction tests conducted at SGS in Brazil continued to confirm
high recoveries of up to 83% for the key permanent magnet rare earth elements, praseodymium,
neodymium, dysprosium and terbium (MREO) equal to any ionic clay hosted deposit in the world. The
outcome of the phase 1 and 2 tests shows that the Ema mineralisation could be processed through any
conventional ionic rare earth element solvent extraction processing facility, supporting the further
development of the project and a pathway to production.
The established industry standard set of recovery conditions was applied to the Ema phase 2 testwork,
being the utilisation of a very weak acid, ammonium sulphate for leaching, pH 4, at ambient
temperatures with a 30-minute leach duration2. These ammonium sulphate leach results show a clear
relationship of high recovery to the highest-grade portions of each mineralised intercept.

ANSTO Metallurgical Test Work
World leading recoveries have resulted from the work recently completed by ANSTO (Australian Nuclear
Science and Technology Organisation). The Ema project has some of the best, if not the best, recoveries
for any ionic clay rare earth project inside of Brazil and perhaps anywhere in the world3 (figure 5).
Figure 5. Rare earth recovery comparison of ionic clay hosted deposits currently defined within Brazil.
See Appendix 1 for full list of details.
The Company has now completed the first phase of metallurgical testwork at ANSTO on an Ema
composite drill sample. This testwork utilised a 49.6kg composite sample collected from 12 auger holes
over 62 samples drilled at Ema.
The scope of work was designed to provide a deeper understanding of the mineralogy and leachability
of the mineralised clays and establish optimal recovery conditions for the high value magnet REE´s.
This testwork applied the same parameters and standard analysis methods as utilised by SGS in Brazil2.
The ANSTO results confirm the very high recovery results obtained from SGS analysis and more
importantly confirm the rare earths are able to be leached over low duration times, at pH 4-4.5, with a
0.15-0.5M ammonium sulphate solution, checking all the critical boxes needed for a fully ionic clay rare
earth deposit.
ANSTO also conducted solution leaching tests on duration times of 1 and 0.5 hours, with the overall
MREE recovery results showing only a slight decrease at 0.5 hours (Figure 7).
Auger holes used in the bulk sample (Figure 8) were distributed within a higher-grade portion of the
mineral resource. Cerium recovery results were very low at only 12% which is always viewed as a positive
for ionic rare earth deposits as cerium generally contributes a significant portion of final product
volumes but generates only US$1-2/kg in revenue.

Três Estados Project
Throughout the quarter, the Company finalised establishment and commissioned a laboratory in
Catalão, Goiás, Brazil for the treatment of platinum, palladium and gold (PGM) samples from the Tres
Estados deposit.
The Company was utilising EcoBiome´s proprietary technology of bacterial leaching which demonstrated
the suitability for unlocking refractory palladium and gold during testing at the Ecobiome facilities in
Houston, Texas in 20234.
At quarter’s end, a number of tests had been completed in Brazil which were benchmarked against
results received from initial testing in Houston utilising similar setup parameters.
To date, palladium and gold has been liberated into solution, but not in the same time frames and grades
that were achieved in the initial test phase conducted in Houston.
At this stage there is no certainty that further test work utilising EcoBiome’s proprietary technology will
result in a material uplift in grades sufficient to justify continued investment in this new technology.
Additionally, a review of the PGM market shows current tepid prices and demand with an uncertain
outlook to 2030.
As a result, the company has therefore decided to concentrate all its cash resources and technical efforts
to progress the Ema rare earths project, which with its unique mineralisation and very high rates of
recovery, is likely to be a near term development project as we enter into the scoping phase of the
project.
As such, the Company’s Brazilian subsidiary has notified EcoBiome of its intent to terminate its
contract with EcoBiome.

About Brazilian Critical Minerals Ltd
Brazilian Critical Minerals Limited (BCM) is a mineral
exploration company listed on the Australian
Securities Exchange.
Its major exploration focus is Brazil, in the Apuí
region, where BCM has discovered a world class Ionic
Adsorbed Clay (IAC) Rare Earth Elements deposit. The
Ema IAC project is contained within the 781 km² of
exploration tenements within the Colider Group.
BCM has defined an inferred MRE of 1.02Bt of REE’s
with metallurgical recoveries averaging 68% MREO
some of the highest for these types of deposits
anywhere in the world.
The Company is currently converting this MRE from
Inferred into the Indicated category with an extensive
drill program which will inform the scoping study and
economic analysis due for completion in late 2024.
