American Marconi Wireless News - Aclara Inaugurates Heavy Rare Earths Pilot Plant in Brazil: Project Receives Full Support from the State of Goias and the Community of Nova Roma

The main products from this pilot plant are Dysprosium and Terbium, which, along with other heavy and light rare earths, will be contained in the carbonate produced by the facility. The Company expects to process approximately 200 tons of clays, resulting in an estimated production of 150 kilograms of heavy rare earth carbonates.

During the event, Aclara conducted a comprehensive tour of the new facility, showcasing its proprietary Circular Mineral Harvesting technology-an innovative and sustainable process at the core of the Company's Carina Project ("Carina" or the "Project"). The new pilot plant incorporates several process optimizations designed to enhance efficiency, lower operating costs, and improve the purity of the final product.

Government officials expressed their full support for the Project's streamlined development, recognizing its strategic potential to position Goias as a global center for sustainable production of heavy rare earths, particularly dysprosium and terbium. They also emphasized the Project's ability to deliver long-term economic growth, social development, and environmental value for the local communities and the State of Goias.

Ramón Barúa, Chief Executive Officer of Aclara commented:

"We extend our most sincere gratitude to the Brazilian authorities and the community of Nova Roma for their extensive support and shared commitment to accelerating the implementation of the Carina Project. During the inauguration, they experienced firsthand our unique proprietary technology, witnessing how clean and simple our process is for producing critical heavy rare earths such as dysprosium and terbium.

The Carina Project´s future production of these key elements will enable the fabrication of approximately five million electric vehicles per year, positioning Goias at the forefront in the global energy transition. Aclara remains fully committed to working in close partnership with the Government of Goiás and community of Nova Roma to ensure the long-term success of the Project and proudly reaffirm our goal to commence operations by 2028. To that end, we are pleased to be on track to submit the Environmental Impact Assessment for the Carina Project in Q2 2025, the Pre-feasibility Study in Q3 2025, and the Feasibility Study in Q1 2026."

Daniel Vilela, Vice Governor of the State of Goiás, commented:

"Goiás will become the epicenter of rare earth mining for the world. Today, I participated in the inauguration of the pilot plant of Aclara Resources in Aparecida de Goiânia, an important milestone marking the start of testing for the Carina Project, which will be implemented in Nova Roma, in northeastern Goias. With an estimated investment of R$2.8 billion (∼US$500M), the project will create thousands of jobs and position our state as a leader in the production of rare earths - strategic minerals for the future of clean technologies such as electric vehicles and wind energy. We continue working toward development that creates opportunities while respecting the environment. Goiás has a future and a clear direction!"

Eleuses Gonzaga, Major of Nova Roma, commented:

"This is a historic moment for me, for Nova Roma, for Aparecida, and for the State of Goias. I extend my sincere thanks for this investment in the city of Nova Roma. I would also like to acknowledge the dedication of our governor, Ronaldo Caiado, and our vice-governor, Daniel Vilela. I am grateful to Aclara for this plant, which I am confident will generate employment opportunities not only for Nova Roma but also for Aparecida and will contribute to the broader development of our State of Goias."

Mr. Lineu Olimpio, the State Deputy and President of the Chamber of Mines and Energy, commented:

"We attended the inauguration of Aclara's pilot plant in Aparecida de Goiânia - the first of its kind in Brazil! It will receive mineral extracted from Nova Roma for the production of motors and electronic components.
It was an important moment for the state, with the presence of the Vice Governor Daniel Vilela, the Mayor of Nova Roma, Eleuses, the Mayor of Aparecida, Leandro Vilela, Aclara's CEO, Ramón Barúa, the Ambassador of Peru, and representatives from the U.S., FIEG, and the mining sector. As President of the Mines and Energy Commission of Alego, we are closely following this progress that places Goiás at the center of innovation!"

The ceremony was also attended by numerous officials from federal, state, and local government, as well as key stakeholders from the private sector.

During the event, Ramón Barúa emphasized that Aclara's operations are driven by principles of responsible mining, highlighting several key innovations and sustainability features from its proprietary technology, the Circular Mineral Harvesting:

• Simple, shallow excavation (average depth of 15 meters) with no blasting;

• Elimination of crushing or milling-two of the most energy-intensive processes in mining-resulting in a significantly reduced carbon footprint;

• Zero liquid discharge;

• No requirement for a tailings dam;

• Recirculation of over 95% of the water used in the process;

• Recovery of 99% of the primary reagent, a commonly used fertilizer;

• Processed clays that are compatible for full reforestation.

"Our heavy rare earth production, dysprosium and terbium, will be essential for establishing a reliable and alternative supply chain for the permanent magnets used in electric vehicles, wind turbines, robotics and other advanced technologies.

As part of this goal, we are also rapidly advancing the development of our separation facility in the Unites States, which aims to transform the heavy rare earth carbonates from the Carina Project into individual rare earth oxides. In parallel, through a joint venture with our Chilean partner, CAP S.A., we are progressing on a project to convert these individual oxides into the alloys needed to produce permanent magnets. Our vision is to become the leading partner for Western customers, delivering high-quality, sustainable mine-to-magnet solutions that drive the future of clean technology," commented Mr. Barúa

Pilot Plant Operation

The new pilot plant incorporates several optimizations to the process flowsheet, building on the Company's previous piloting efforts in Chile, where 25 tonnes of clays from the Carina Project were processed. The Company expects to process approximately 200 tons of clays, resulting in an estimated production of 150 kilograms of heavy rare earth carbonates. Aclara's optimized approach is focused on increasing efficiency, reducing costs, and improving the purity of the final product. The Company aims to achieve the following objectives:

• Validating the newly optimized closed-circuit flowsheet at semi-industrial scale,

• Validating processing parameters and the process flowsheet design to support the upcoming Pre-Feasibility Study (Q3 2025) and Feasibility Study (Q1 2026), both led by Hatch Ltd.,

• Generating a high purity heavy rare earth carbonate for our future pilot plant for separation in the United States and in support of future off-take agreements, and

• Demonstrating to relevant stakeholders the environmental sustainability of the process design.

• Generating processed clays to confirm that they are chemically stable when returned to the field,

• Confirming the amenability of the clays to support the revegetation of the reclaimed site,

IP Rights

The proposed process flowsheet has two patents in place that protect this innovation. The first has been granted in all the countries that were requested viz. Chile, Brazil, US, and China, while the second patent has recently been filed and is pending approval.
