Location of 2026 MRE outline (Indicated + Inferred) with red dots representing completed drilling during 2025. A total of 49 holes of the expanded 101-hole drilling program have now returned assay results. Results generally returned thick mineralised intercepts with the highest grades of NdPr located at the bottom of the auger holes within the semi-weathered zone, directly above the fresh rock interface. Drilling was designed on 300m centres within the 20-year mine plan area (Figure 2). Results indicate a strong increase in magnetic rare earths (MREO) grade towards the base of the weathered profile near the saprock interface over intervals of generally 5-10m, considered ideal for in-situ leaching. The significant increase in the proportion of valuable heavy rare earth elements (HREEs) to over 31% of MREO composition at the end of the holes underscores the economic potential of the lower saprolite zone. This enhancement suggests that deeper drilling in these areas could further enhance the viability of a low-cost in-situ leach operation, supporting the ongoing BFS workstreams, with completion targeted for Q2 2026.

Permitting BCM continues to advance its permitting pathway, with key applications currently under review by both the Agência Nacional de Mineração (ANM) and the Instituto de Proteção Ambiental do Amazonas (IPAAM). Ongoing engagement with both agencies remains active, structured, and constructive as the project progresses through the regulatory process. Regular informal interactions, combined with scheduled technical meetings, are facilitating efficient knowledge transfer and alignment between BCM and the relevant authorities. These discussions have focused on ensuring a clear understanding of the project’s layout, operating methodology, and environmental management framework, particularly in the context of its low-impact development approach. • Interactions with both ANM and IPAAM have been consistently positive and progressive, with regulators demonstrating a practical and solutions-oriented approach to advancing the review process • BCM has successfully articulated the project’s ESG-led development strategy, including its low- disturbance footprint and alignment with modern environmental standards • The agencies’ engagement reflects growing familiarity with the project and its technical characteristics, supporting a smoother pathway through subsequent approval stages Both ANM and IPAAM have issued formal requests for additional information and clarifications, representing a standard and constructive step in the permitting process.

The Company is now focused on advancing the final costing and price estimation of both the capital and operating cost centres. The majority of the capital estimation is being conducted in Brazil ahead of the financial model creation. Both items have already been awarded to Brazilian entities with work scheduled through the majority of the June quarter. Offtake Discussions Following delivery of MREC product to selected offtake partners in the December quarter, the focus this period has been on product qualification and technical engagement. This was supported by an extensive engagement program across the United States, PDAC in Toronto, and several weeks on the ground in Brazil. What is clear from these discussions is that sentiment in the US remains extremely strong for rare earths, with increasing competition among downstream players to secure reliable supply. Critically, access to Western rare earth feedstock remains constrained, which is now driving upward pressure on NdPr pricing, and we are beginning to see a structural pricing divergence for dysprosium and terbium relative to Chinese benchmarks. This dynamic reinforces the strategic positioning of Ema as a potential long-term supplier into a tightening global market. Geotechnical Drilling During the quarter, a series of vertical diamond drill holes were completed through the wellfield anticipated to provide product during the first years of production. Core was collected to assess both the physical and lithostructural characterisation of the rock mass, with particular emphasis on the saprolite to solid bedrock contact which is critical in preventing loss of leach solution during operations. Results of drilling have also been incorporated in the hydrogeological assessment currently being completed by WSP in Adelaide.

Figure 5 – Drill core from hole NGG-07 drilling to a final depth of 26m, intercepting solid felsic volcanic bedrock at 11.75m. This hole was drilled for physical core only. No assaying of samples has been completed and no interpretation of grade can be inferred from the physical core. Hole NGG-07 intersected the targeted clay, saprolite and fresh rock rhyolitic bedrock hosting the Ema rare earth deposit. No rare earth mineralisation is observable due to the intense nature of the weathering through the saprolite zone. No quantitative estimates of grade or metal content are reported. The disclaimer There were no visual observations of mineralisation. No laboratory samples were submitted due the hole being drilling for physical properties of the rock (saprolite/bedrock interface) and depth to bedrock determinations only.
