5E Advanced Materials (FEAM) announced that CEO Paul Weibel discussed the company’s recently announced agreement to acquire certain assets of Searles Valley Minerals at the Water Tower Research Insights Conference held on September 22, 2026.
The proposed acquisition is expected, upon closing, to help 5E transition from a pre-revenue developer to a revenue-generating U.S. critical minerals producer by adding existing production capabilities, an established customer base and infrastructure to its platform. Weibel outlined the opportunity to combine Searles Valley’s operating business with 5E’s Fort Cady boron resource, the potential to support Fort Cady’s development while reducing its standalone financing burden, and the longer-term goal of building a scaled U.S. platform across boron, advanced boron materials and other critical mineral products.

5E Advanced Materials (NASDAQ:FEAM) reported progress in its magnet-grade ferroboron (FeB) development program, a key step in its mine-to-magnet strategy linking the Fort Cady boron resource to higher-value downstream products. Independent X-ray diffraction testing confirmed formation of the intended iron boride (Fe2B) phase in samples processed at 1,300°C.
Density-based analysis showed conversion efficiency for the leading Fe2O3 + B2O3 precursor increased from about 11% at 1,200°C to an average 51%–62% at 1,300°C. 5E has started testing at 1,400°C and is planning an approximately 500-gram batch with a third-party metallurgical partner to support process optimization, characterization and future customer samples. The ferroboron program targets applications in NdFeB permanent magnets, specialty steels, industrial automation and defense, and builds on recent White House recognition of Fort Cady and the Export-Import Bank of the United States’ $8 million investment in the project.
