The raw solution averaged 877 ppm total rare earth oxides (TREO), with approximately 50% of the solution being processed through the steps of impurity removal and MREC precipitation to generate 650 grams of high value & high quality MREC containing 52.5% TREO. Of the 15 rare earth oxides recovered within the MREC, the four economically critical oxides praseodymium, neodymium, dysprosium and terbium collectively (MREO) represented 41.5% (Table 1). This places the Ema MREC as one of the highest MREO products in the western world. This result demonstrates the Ema Project’s ability to produce a high-purity, magnet-rich rare earth product using low-cost ISR processing, reinforcing its strategic importance as a potential Western supply of critical rare earths.

Mr. de Castro has sufficient experience which is relevant to the type of deposit under consideration and to the reporting of exploration results and analytical and metallurgical test work to qualify as a competent person as defined in the 2012 Edition of the Joint Ore Reserves Committee (JORC) “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Mr. Castro consents to the report being issued in the form and context in which it appears. Appendix 1 The following Table and Sections are provided to ensure compliance with JORC Code (2012 Edition). 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. • Exploration results are based on auger drilling conducted by BCM´s exploration team. • The data presented is based on the assay of soils and saprolite by auger drilling at 1m sample intervals. • Sampling was supervised by a GE21 geologist or a GE21 field assistant. • Every 1-metre sample was collected in a big plastic bag in the field and transported to the exploration shed to be dried in the muffle. prior to homogenisation. • Samples were homogenised and subsequently riffle split with about 1 kg sent to SGS for analysis and a similar amount stored. • 1 certified blank sample. 1 certified reference material (standard) samples and 1 field duplicate sample were inserted into the sample sequence for each 25 samples.

The primary objective of the work was to develop a product utilising magnesium based reagents allowing for a final demonstration and marketing product to be developed. Specific tasks included; • Carrying out a large scale impurity removal test on liquor generated from field trials in Brazil; • Carrying out processing through IX to remove primary uranium on the IR liquor; • Carry out a large scale rare earth carbonate precipitation test on the IR liquor; • Analyse the MREC product for a full suite of elements, including radionuclides; Flowsheet for MREC Production: The process included the following key steps: 1. Impurity Removal: Using magnesium oxide and magnesium bicarbonate, a two-stage precipitation process increased the pH from 4.5 to 7.5 under ambient conditions. This also included uranium removal via ion exchange to remove residual uranium. 3. MREC Precipitation: Magnesium bicarbonate was used as a precipitating agent to produce the final MREC product. Final Product: MREC containing 52.5% TREO and 41.5% of MREO (100% basis) and impurity levels ~<2.0%. Residual liquids from the desorption and precipitation stages were analysed to assess impurity removal efficiency. Laboratories and Analytical Techniques: - ANSTO: Conducted most of the process tests and analyses using the following techniques: - XRF for major elements, including Al, Ca, Fe, K, Mg, Mn, Na, Si, and others. - ICP-OES for in- house analysis of gangue minerals. ICP-MS for rare earth elements, including Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sc, Sm, Tb, Th, Tm, U, Y, and Yb. At the ALS Geochemistry Laboratory: Performed external analysis of rare earths and radionuclides using lithium tetraborate fusion digest followed by ICPMS. These tests confirmed the quality of the MREC product, has low impurity levels, and complies with market specifications. Field Samples: • 1 blank sample. 1 certified reference material (standard) sample and 1 field duplicate sample were inserted by BBX into each 25- sample sequence. • 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. • The assay technique used for REE was Lithium Metaborate Fusion ICP-MS (SGS code ICP95A and IMS95A).
