The test also showed that the rare earths are readily soluble using MgSO4 resulting in high recoveries after the passing of only 1.9 pore volumes (the ratio of the material's air volume to total volume).” Andrew Reid, Managing Director, commented: “Over the past 6 months the team has been actively working on the steps required to maximise the recoveries of rare earths whilst minimising impurity levels. The ANSTO column test followed the same sequence, the same MgSO4 reagent and concentration, as well as the same physical parameter setup in the column to mimic ISR. These results give us confidence in being able to replicate these lab tests in the field with the pilot trial commencing in the coming weeks.” Brazilian Critical Minerals Ltd (ABN: 82 089 221 634) AUS: Level 28, 140 St Georges Terrace, Perth WA 6000 T +61 8 6383 7820 BRA: Av Jornalista Riccardo Marinho, 360, Sala 113, Barra da Tijuca, Rio de Janeiro T +55 21 2439 57 ASX Announcement Released 12th March 2025 https://braziliancriticalminerals.com/ Investor Hub: https://braziliancriticalminerals.com/auth/signup Brazilian Critical Minerals Limited (ASX: BCM) (“BCM” or the “Company”) is pleased to announce that results have been received from an ANSTO column test that was set up and run to mimic conditions of temperature, pressure, density and moisture as those measured from in-situ samples at the Ema project. The Company requested ANSTO to supplement their ongoing column work with a standard ISR column test on the Ema material. The test involved packing the ore into a column to achieve a bulk density as close as possible to that underground and feeding the MgSO4 lixiviant through the mineralised material at a pressure equivalent to that at the depth of the orebody, with the column in a vertical configuration. The aim of the ISR test was to provide a more accurate assessment of the permeability of the undisturbed clay underground, as well as provide relevant leaching data such of rare earth extraction vs pore volume as well as MgSO4 reagent consumption rates. Results A head grade analysis of the sample was determined at ALS Geochemistry Laboratory, Brisbane to contain 829ppm TREY (15 REE elements + Yttrium) of which 30% or 250ppm were of the elements Nd, Pr, Dy and Tb. These results have not been converted to rare earth oxide form. Over the course of 28 days, the MgS04 lixiviant at pH 4.5 was injected through the column which resulted in high recoveries of TREY and MREE relative to the recent values used in the Ema scoping study1 (table 1). Key takeaways; • • • High recoveries of MREE achieved over the test period (table 1), with most of the recovery occurring over only 17 days <2 pore volumes (the ratio of the material's air volume to total volume) required to achieve final recoveries (Figure 1.) Individual MREE recoveries were; o Praseodymium 85%; o Neodymium 72%; o Terbium 70%; and o Dysprosium 63% Table 1.

To date, the Company has completed numerous field slug tests1 and column test results both within Brazil and at Australian Nuclear Science & Technology Organisation (ANSTO) in Sydney, all of which have shown that there is a degree of permeability within the weathered clays that allows solution flow and the ability to ionically recover rare earths into solution.

JORC (2012) Table 1 – Section 1: Sampling Techniques and Data for auger hole drilling Item JORC code explanation Comments 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 representativity 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. • Metallurgical results are for a 60kg composite sample, not dried, maintaining in-situ moisture level, from a twin auger hole EMA-TR-188, from 4m to 10m. • Every 1-metre sample was collected in a plastic bag in the field, immediately sealed to preserve natural humidity. • Sampling was supervised by a BCM geologist. • Each metre weighted around 10kg. • The plastic bags as received from the field were sent to ANSTO. Drilling Techniques • Drill type (eg core. reverse circulation. openhole hammer. rotary air blast. auger. Bangka. sonic. etc) and details (eg core diameter. triple or standard tube. depth of diamond tails. facesampling bit or other type. whether core is oriented and if so. by what method. etc). • Auger drilling was completed by a hand-held mechanical auger with a 3” auger bit. The drilling is an open hole. meaning there is a significant chance of contamination from surface and other parts of the auger hole. Holes are vertical and not oriented. Drill Sample Recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • No recoveries are recorded. • • Measures taken to maximise sample recovery and ensure representative nature of the samples. The operator observes the volume of each metre and notes any discrepancy. • No relationship is believed to exist between recovery and grade. • All exploration holes were logged by GE21 geologist. detailing the colour. weathering. alteration. texture and any geological observations. Care is taken to identify transported cover from in-situ saprolite/clay 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 material. • 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.

Commentary • Weighted averages were calculated for all intercepts. • 500ppm TREO cut-off grade was applied to define the relevant intersections. • No metal equivalent values reported. • Significant values of REE were reported for the auger samples. • Mineralisation orientation is not known at this stage although assumed to be flat. • The downhole depths are reported, true widths are not known at this stage. • 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. • Maps and tables of the auger holes location and target location are inserted in previous announcements. 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. • Relevant REE mineralisation with grades higher than 500ppm TREO in auger holes were reported with confirmation of IAC (Ionic Adsorbed Clay) type mineralisation obtained in almost all the auger holes from phase 1 in this same geological setting. 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. • No other significant exploration data has been acquired by the Company.
