The expansion enables ReElement to supply essential defence minerals.
The Noblesville facility specializes in producing ultra-pure separated defence elements and rare earth oxides with purities ranging from 99.9% to 99.999%. The expansion allows ReElement to supply essential defence and advanced technology minerals, including antimony, dysprosium, gadolinium, gallium, germanium, samarium, terbium, and yttrium, alongside traditional magnet elements like neodymium and praseodymium.
This investment supports near-term supply to defence and advanced technology sectors, while the company’s Marion Supersite continues development to provide large-scale production capabilities for rare earths and related critical minerals.
ReElement recently added nine separation columns to the expanded facility, along with key equipment such as an ICP-MS machine, to ensure consistent commercial output of 99.999% pure products. The company is completing the build-out while maintaining full daily operations at the Noblesville site.
Simultaneously, more than 60% of the equipment for Marion’s initial contracted growth phase has been ordered, identified, or installed, aiming to achieve large-scale refining capacity for magnet-grade rare earths, battery materials, antimony, and other defence elements.
Jeff Peterson, COO of ReElement Technologies, said: “This expansion of our Noblesville facility showcases the flexibility and scalability of our refining platform and positions us to lead in meeting the growing yet complex demands of both the defence and commercial markets.
“By expanding our existing operational footprint in Noblesville, we can quickly scale production of the high-purity separated elements we have already validated and are producing today. This step enables us to expedite deliveries to our defence industrial base customers while maintaining our focus on rapid deployment of our Marion facility.
“Even with this added capacity in Noblesville, the growth ahead will require significant utilisation of Marion, particularly for battery, magnet, and defence elements that we have scheduled for next year. We are excited to leverage this additional operating space as we continue to showcase how ReElement’s refining platform materially de-risks and strengthens critical mineral supply chains.”
ReElement Technologies’ rare earth element separation process uses patented and proprietary refining chromatography methods, ensuring the production of high-purity minerals that are critical for defence, advanced technology, and industrial applications.
The facility expansion represents a significant step in increasing the resilience and reliability of critical mineral supply chains, reinforcing ReElement’s position as a leader in high-purity REE production for global markets.
