Aclara Announces Results from Technical Reports on Its Integrated Heavy Rare Earths Supply Chain

13:00 Uhr  |  ACCESS Newswire

TORONTO, April 13, 2026 - Aclara Resources Inc. ("Aclara" or the "Company") (TSX:ARA) is pleased to announce the results of a series of technical studies supporting its integrated heavy rare earths supply chain, spanning from mining operations to the production of permanent magnet alloys ("mine-to-alloys" strategy). The studies include a feasibility study for the Company's flagship asset, the Carina Project prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), a scoping study for the Company's separation project ("Project Dynamo"), and a Front-end Loaded 2 (FEL 2) Technical Report (pre-feasibility study level) for its metals and alloys project.

Aclara is advancing two ionic clay deposits in Brazil and Chile capable of producing a mixed rare earth carbonate ("MREC") with very high concentrations of heavy rare earth elements ("HREEs"), particularly those restricted under China's export controls. To help build a reliable supply chain outside of China, Aclara is also establishing a U.S.-based processing hub that will separate MREC into individual rare earth oxides and further transform these oxides into metals and alloys tailored to the needs of permanent magnet manufacturers.

Aclara's value proposition is anchored in its vertically integrated, mine-to-alloys business model, designed to maximize commercial viability while reducing execution risk, optimizing costs, and accelerating development timelines. The Company is establishing a fully traceable heavy rare earth supply chain that meets the highest environmental and social standards at every stage, while maintaining full control over mining and processing to ensure consistency, quality, and reliability. Its projects are purpose-built to enhance geopolitical independence and strengthen supply chain resilience.

Backed by leading industrial shareholders such as the Hochschild Mining plc ("Hochschild") and CAP S.A. ("CAP"), and supported by strategic institutions such as the U.S. International Development Finance Corporation, which has committed initial funding and retains a pathway for further investment, Aclara has deployed over US$250 million to date and is well-positioned to fund its integrated growth mine-to-alloys strategy.

Aclara's CEO, Ramón Barúa, commented:

"At Aclara, our ambition is to become a long-term supplier to high-technology industries that depend on rare earth elements. Achieving this requires building a supply chain that is reliable, consistent, and sustainable. Today's announcement reflects nearly eight years of dedicated work, during which we have developed the mineral reserves, the technology, and the engineering capabilities to establish ourselves as a leader in the supply of rare earth products.

Our competitive advantage is grounded in three pillars: our ionic clay deposits - the world's primary source of heavy rare earths - a portfolio of proprietary technologies that enable us to convert those clays into permanent magnet alloys, and the backing of strategic partners who contribute not only capital but also deep industrial and mining expertise across the Americas.

The results published today are a testament to the Aclara team's commitment to delivering, through a fast-track approach, an initial robust and vertically integrated supply chain for both heavy and light rare earths. These three studies form the foundation of our core strategy and will soon be complemented by additional growth opportunities, including Penco, the separation of non-magnetic rare earths, continued mineral exploration, and more. We will also continue to work towards applying our technology, in the medium term, in Brazil and other countries where we operate. We remain firmly convinced that the supply-demand imbalance - particularly for heavy rare earths - will continue to widen, setting the stage for the successful execution of our strategy."

Key Financial Results

Expected Production ¹

Notes:

1. Annual average does not consider the first year of ramp-up and the last year of ramp-down.

2. Didymium ("NdPr") metal production: NdPr metal production is based on a maximum annual production of 1,000 tonnes of didymium oxide ("NdPr oxide"), resulting in approximately 131 tonnes of excess NdPr oxide, which may either be sold directly or further processed into metal.

3. NdFeB Alloy: The nominal capacity of the NdFeB alloy plant is 3,500 tonnes per year; however, production has been capped based on the maximum output of NdPr metal derived from the Carina Project.

4. Phase 2: Aclara is currently developing separation circuits for yttrium, gadolinium, and samarium. The financial results for Project Dynamo do not include any contribution from the separation of these elements, which represents potential upside to the project. Similarly, the Company's metals and alloys business is evaluating the expansion of its metallization capabilities to include these elements, leveraging its proprietary technologies to enable their production.

5. Phase 3: To be developed in line with market demand.

Mining - Carina Project, Goiás, Brazil (Upstream)

The Carina Project is an advanced-stage ionic clay-hosted heavy rare earth deposit located in Goiás, Brazil. The Carina Project is designed to produce a high-purity MREC through a low-impact, technology driven and value-added extraction process. The operation contemplates conventional open-pit mining but, due to the friable nature of the clays, does not require blasting, crushing, or milling, thus significantly reducing energy consumption and carbon emissions. Rare earth elements are recovered using Aclara's proprietary Circular Mineral Harvesting process, an ion-exchange technology that uses a recyclable ammonium-based solution to selectively extract rare earths. The process is designed to minimize environmental impact, with high rates of water and reagent recycling and no requirement for a tailings storage facility. The resulting high-purity MREC is intended to be further processed at Aclara's U.S.-based separation and downstream facilities, forming part of the Company's vertically integrated "mine-to-alloys" supply chain.
