Aclara Resources Inc. ("Aclara" or the "Company") (TSX:ARA) is pleased to provide the drilling results from its Phase 1 reverse circulation ("RC") drilling campaign executed between November 2023 and April 2024 on its regolith-hosted ion adsorption clay project, known as the "Carina Module", located in the State of Goiás, Brazil. The Phase 1 RC drilling campaign, which was comprised of 1,998 meters of drilling within 80 drill holes, has confirmed that the mineralization extends through the full depth of the regolith to the bedrock and provides a greater level of certainty regarding the geological interpretation of the deposit and the existence of rare earth elements throughout the full cross-section of the regolith
Highlights
- Depth Mineralization Confirmed: Results from the Phase 1 RC drilling campaign confirm that the mineralisation extends through the full depth of the regolith to the bedrock. The average high-grade mineralization thickness has increased from 6.1 meters reported in the previous auger drilling campaign to 11.1 meters.
- Consistent Grades and Rare Earths Distribution: The results reflect that the Total Rare Earth Oxide ("TREO") 1 and the Desorbible Rare Earth Oxide ("DREO") 2 grades as well as the Rare Earths Distribution in the product basket, are consistent with those reported in the previous auger drilling campaign. Table 1 below compares the results of the RC drilling campaign with the auger drilling campaign and Table 2 provides a selection of high-grade drillhole results.
- Improved Reliability: The results provide a greater understanding of the mineralised horizons through the full depth of the regolith to the bedrock and will support execution of the Phase 2 drilling campaign, which will seek to convert the known inferred mineral resources to a measured and indicated resource category.
- Metallurgical Compatibility: The Carina Module clays have been shown to be amenable to rare earths extraction using the same metallurgical process (the "Circular Mineral Harvesting" process) developed for the Chile-based Penco Module, which utilizes ammonium sulfate as the primary leaching solution. A 25-tonne bulk sample of Carina clays was processed in the Aclara Pilot Plant in Concepción, Chile in Q1 2024, where leaching results were consistent with the drill core assays.
The full set of results is included in Table 3 at the end of this press release. These results supplement the results obtained from the auger drilling campaign undertaken between February 2023 and September 2023, which comprised 1,630 meters within 201drill holes. The results of the auger drilling campaign also formed the basis of the maiden mineral resource estimate announced in Aclara's press release dated December 12, 2024, and which supported the preparation of the Carina Module Preliminary Economic Assessment(" PEA") dated January 12, 2024.
Next Steps
The Phase 1 RC drilling campaign results have provided the Company with a basis to further advance the following activities:
- issuance of an updated Mineral Resource Estimate planned for July 2024;
- issuance of an updated PEA of the Carina Module during Q3 2024;
- execution of a 15,200-meter Phase 2 RC drill campaign to convert inferred mineral resource to a measured and indicated mineral resource category, which is expected to commence in June 2024; and
- execution of a metallurgical test campaign during H2 2024 and H1 2025. Sample collections will be obtained through sonic drilling and sent to SGS Lakefield for mineralogical and recovery characterization, to serve as an input for the pre-feasibility study, as well as form the basis for a new semi-industrial scale piloting operation scheduled to occur in 2025.
Aclara COO, Barry Murphy, commented:
"We are very pleased with the results obtained from Aclara's recent RC drilling campaign as they have confirmed our expectation that the Carina Module deposit will increase in size to become a truly world-class heavy rare earth asset. Based on the positive Phase 1 RC drill results, the Company will be updating the Carina Module's mineral resource estimate and Preliminary Economic Assessment and proceeding with the next phase of RC drilling aimed at converting the known mineral resource from an inferred to a measured and indicated level of categorisation. The results obtained from Phase 2 RC drilling campaign are expected to provide support for the Carina Module prefeasibility study, as well as to provide samples for a more comprehensive metallurgical test work programme, which we believe will demonstrate the extraordinary value of this deposit."

Reverse Circulation Drilling Campaign Summary
A total of 1,998 meters of drilling within 80 RC drill holes was carried out from November 2023 to April 2024 as part of an exploration drilling campaign covering approximately 700 hectares within the area of the Carina Module (see Figures 1, 2, 3 and 4 below). The primary objectives of the drilling initiative were to:
- obtain additional information to fully assess the Carina Module's potential (both laterally and at depth);
- obtain guidance for future RC drilling campaigns, as needed to contribute to the definition of the Carina Module's indicated and measured resource estimates; and
- establish a base for a future metallurgical test sample collection.

About Aclara
Aclara Resources Inc. (TSX: ARA) is a development-stage company that is focused on heavy rare earth mineral resources hosted in Ion-Adsorption Clay deposits. The Company's rare earth mineral resource development projects include the Penco Module in the BioBio Region of Chile and the Carina Module in the State of Goiás, Brazil.
Aclara's rare earth extraction process offers several environmentally attractive features. Circular Mineral Harvesting does not involve blasting, crushing, or milling. Additionally, it does not generate tailings, eliminating the need for a tailings storage facility. The extraction process developed by Aclara minimizes water consumption through high levels of water recirculation made possible by the inclusion of a water treatment facility within its patented process design. The ionic clay feedstock is amenable to leaching with a common fertilizer main reagent, ammonium sulphate. Further, harmful levels of radionuclides, typical of hard rock rare earth deposits, are not concentrated within Aclara's processing flowsheet. In addition to the development of the Penco Module and the Carina Module, the Company will continue to identify and evaluate opportunities to increase future production of heavy rare earths through greenfield exploration programs and the development of additional projects within the Company's concessions in Brazil, Chile, and Peru.
