About Aclara Resources Inc.

Aclara, a Toronto Stock Exchange-listed company, is focused on building a vertically integrated supply chain for rare earth alloys used in permanent magnets. This strategy is supported by Aclara's development of rare earth mineral resources hosted in ionic clay deposits, which contain high concentrations of the scarce heavy rare earths, providing the company with a long-term, reliable source of these critical materials. The company's rare earth mineral resource development projects include the Carina project in the state of Goias, Brazil, as its flagship project and the Penco Module in the Biobio region of Chile. Both projects feature Aclara's patented technology named circular mineral harvesting, which offers a sustainable and energy-efficient extraction process for rare earths from ionic clay deposits. The circular mineral harvesting process has been designed to minimize the water consumption and overall environmental impact through recycling and circular economy principles. Through its wholly owned subsidiary, Aclara Technologies Inc., the company is further enhancing its product value by developing a rare earth separation plant in the United States. This facility will process mixed rare earth carbonates sourced from Aclara's mineral resource projects, separating them into pure individual rare earth oxides. The company also operates a rare earth separation pilot plant at the Virginia tech corporate research centre in Blacksburg, Va. Additionally, Aclara, through a joint venture with CAP, is advancing its alloy-making capabilities to convert these refined oxides into the alloys needed for fabricating permanent magnets. This joint venture leverages CAP's extensive expertise in metal refining and special ferro-alloyed steels. Beyond the Carina project and the Penco Module, Aclara is committed to expanding its mineral resource portfolio by exploring greenfield opportunities and further developing projects within its existing concessions in Brazil, Chile and Peru, aiming to increase future production of heavy rare earths.
