5E Advanced Materials, Inc.

5E Advanced Materials, Inc. is a development-stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials. The company's business strategy involves developing capabilities from upstream extraction and sales of borates, calcium-based co-products, and potentially other byproducts like lithium carbonate, to downstream advanced boron material processing and development. 5E Advanced Materials, Inc. holds 100% of the rights to the 5E Boron Americas (Fort Cady) Complex, referred to as the "Project," located in southern California. These rights are held through ownership and lode claims filed with the United States Bureau of Land Management, via its wholly owned subsidiary 5E Boron Americas, LLC. The Project is supported by boron reserves and a lithium resource, with the boron contained in colemanite. The company's small-scale facility (SSF) at the Project is currently operational, gathering data to support the establishment of a commercial-scale facility. The Project is based on a conventional colemanite deposit, which is a hydrated calcium borate mineral, and is believed to be one of the largest known new conventional boron deposits globally. This deposit hosts a mineral resource and reserve from which the company intends to extract and process borates, advanced boron materials, calcium-based co-products, and potentially other byproducts such as lithium carbonate on a commercial scale. The facility was designated as Critical Infrastructure by the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency in 2022, and boron was added to the U.S. Department of the Interior's 2025 Critical Minerals List on November 7, 2025.
