The Ema ionic REE project stands out as a unique and highly promising Mineral Resource in Brazil's rare earth element (REE) sector, offering several key highlights: • Analogous to China’s iREE Deposits: The project’s similarity to the world-renowned ionic clay REE deposits in southwest China, formed over felsic volcanic rocks, sets it apart from other Brazilian REE projects • World-Class Potential: China's deposits are the largest known ionic clay REE sources, emphasizing the strategic importance and potential scale of the Ema project • Extensive Land Area: The project spans a vast 189 km² of felsic volcanic terrain. • The similarity to Chinese iREE deposits strengthens the confidence in the project’s potential for economically viable development • 55% of tenement area remains to be explored and indicates the possibility of significant resource expansion as additional drilling is undertaken • The project holds strategic importance for Brazil's REE sector, potentially positioning it as a major player in the global supply chain 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 21st February 2025 https://braziliancriticalminerals.com/ Investor Hub: https://braziliancriticalminerals.com/auth/signup The Ema project’s unique characteristics and ongoing exploration success underline its potential to contribute meaningfully to the global demand for rare earth elements. Geology and Mineralisation The rare earth element (REE) mineralisation is hosted within a tropical lateritic weathering profile developed atop felsic volcanic and volcaniclastic rocks, including rhyolites and ignimbrites. This weathering profile has facilitated the enrichment of REEs, making the deposit a valuable target for extraction. The REE mineralisation occurs primarily in the weathered portions of the profile. In these zones, REEs originally contained in primary minerals such as monazite and xenotime are released through weathering processes. The dissolved REEs migrate downward through the regolith profile and are subsequently adsorbed onto newly forming fine aluminosilicate clay particles, including kaolinite, illite, and smectite. The Ema deposit is characterised as an undulating ionic clay-hosted deposit, conforming to the rise and fall of the local topography. The mineralisation has been geologically interpreted as a singular, contiguous deposit spanning an area of approximately 82km². This interpretation was developed through a systematic approach aimed at ensuring the MRE was both well-constrained and reflective of expected subsurface conditions. Key steps in the process included the use of both factual and interpreted geological data to guide the development of the mineralisation model. Geological matrices were developed to aid in interpretation, facilitating the definition and construction of estimation domains. This approach ensured that the resource estimation was firmly rooted in the underlying geology, delivering a robust and representative MRE for the deposit. The methodologies employed demonstrate a thorough understanding of the deposit's geologic characteristics, enhancing confidence in the accuracy and reliability of the MRE. All of the data used in the MRE has been gathered from hand auger drilling. This clay core is geologically logged and subsequently sub-sampled prior to analysis. The sampling intervals are domained by geological constraints (e.g. rock type, and alteration). All geology input is logged and validated by the relevant area geologists, incorporating an assessment of sample recovery. No defined relationship exists between sample recovery and grade. Drilling Drilling was conducted with hand-held augers, which offers the advantage of low-cost, rapid deployment and mobility. Drill results have now been received for 244 infill holes of the 270-hole program. The remaining 26 holes were not drilled due to weather conditions preventing site access and will be drilled during the 2025 drill campaign.

Topography is moderately undulating across most of the project area with holes within the starter zone (Priority 1-3) drilled on a nominal 300m grid spacing. Prior drilling programs were conducted at 800m spacing. The entire enriched zone at Ema is generally contained within the 10 metres of regolith sitting directly above the saprock/fresh rock interface, which display a clear increase in grades with depth.

The recovery data indicates a significant proportion of the REE’s are present as ionically adsorbed clays, confirming that Ema, which currently stretches over 82km2 has the potential to become one of the largest ionic clay hosted deposits defined outside of China. Weathering Model – Chemical Index of Alteration (CIA) The mineralised horizons were constrained by a weathering model constructed using the Chemical Index of Alteration (CIA; Nesbitt & Young, 1982), which showed high reliability, made possible by the availability of major oxide assays for each interval (Figure 5, 6 & 7). Figure 5. Weathering Model Plan View and Section Location (A-A1, B-B1) over entire global resource area. HW = high weathering, IW = Intermediate weathering, LW = low weathering, FR = fresh rock.

Sampling and Sub-sampling Techniques Holes were sampled by BCM´s exploration team, with sampling being supervised by a GE21 geologist and field assistants. Every 1-metre sample was collected in a plastic bag in the field and transported to the exploration shed to be oven dried prior to homogenisation. Samples were homogenised and subsequently riffle split with about 1 kg sent to SGS for analysis and a similar amount stored.

The <3mm rejects and the 250-300 grams pulverised sample were returned to BCM for storage. All samples generated have identification that is registered in internal spreadsheets. This identification is linked to the name of the hole and interval to which the sample belongs. Sample Analysis Method The assay technique used for REE analysis was Lithium Metaborate Fusion ICP-MS (SGS code ICP95A and IMS95A). This is a recognised industry standard analysis technique for REE suite and associated elements. Elements analysed at ppm levels included the following minerals and elements: Ba Gd Rb U Cu Ce Hf Sm V Ni Co Ho Sn W Cs La Sr Y Dy Lu Ta Yb Er Nb Tb Zr Eu Nd Th Zn Ga Pr Tm Co The sample preparation and assay techniques used are industry standard and provide total analysis.

GE21 used Leapfrog Geo and Edge software for 3D modelling, with domains based on weathering horizons defined as follows (figure Error! Reference source not found.): • • • • High Weathering: CIA ≥ 93% Intermediate Weathering: CIA ≥ 82% Low Weathering: CIA < 82% Fresh Rock: EOH of auger drilling Most drillholes did not cross the complete weathering profile; with some holes stopping in the pedolith or saprolite domains due to the depth limitations of the auger semi-compact rocks. The top of fresh rock horizon was assumed at the end of each auger hole. Figure 9 shows a cross-section view of the geological model.

Standard laboratory QA/QC procedures were followed, including inclusion of standard, duplicate and blank samples. The assay results of the standards fall within acceptable tolerance limits and no material bias is evident. Data analysis GE21 developed data analyses, including descriptive statistics for light and heavy REE’s by domain, exploratory data analysis, and geostatistical analysis. They identified outliers as breaks in probability plot distribution curves for each element by domain (Table 4). Bulk density Average bulk density values for each weathering zone type were defined based on 57 sand replacement in situ density assays executed by the BCM technical team. Samples were collected in pits adjacent to auger holes at 2 metre depth intervals. Density values were correlated to a specific weathering zone type based on assay results (CIA) for average density definition. The bulk density applied in the block model was dry based. Block model and Grade Estimation The block model dimensions were based on average drill spacing, with sub-blocks used for adhesion between modelled solids and the selective mining unit. The 3D block model was constructed for resource estimation purposes in Leapfrog EdgeTM software. The parent block dimensions were 100m x 100m x 4m, sub-blocked to 25m (X) x 25m (Y) x 2m (Z). Variographic analysis was performed for grouped domains (HW, IW and LW) and elements (TREO), with experimental variograms constructed in different directions. No continuity differences were observed in different directions in the horizontal plane, therefore, horizontal/omnidirectional experimental variograms were chosen (Table 3 Table 3). The mineral resource was estimated using ordinary kriging (Table 4Table 4. ) and validated the grade estimate through visual analysis and global and local bias analysis using the nearest neighbour as the comparison estimate.
