USA Rare Earth Inc has appointed Fluor Corp and WSP Global Inc as EPCM partners to advance the definitive feasibility study for its Round Top rare earth project in Texas, targeting heavy rare earths and critical magnet materials. The mandate covers process plant, mine infrastructure and associated large-scale infrastructure delivery, drawing on Fluor’s mining and processing design capability and WSP’s experience in complex project execution. For geotechnical and civil teams, early EPCM involvement signals imminent definition of pit design, waste storage, haul roads and water management concepts ahead of permitting and financing.

CIMIC Group subsidiaries Sedgman and Leighton Asia have secured separate contracts from Hindustan Zinc Limited to help deliver India’s first zinc tailings recycling facility at the Rampura Agucha Mine in Rajasthan. Sedgman will focus on process plant and tailings treatment infrastructure, while Leighton Asia will provide project delivery and construction services for the brownfield site. The project signals large-scale reprocessing of legacy zinc tailings at one of the world’s largest zinc operations, with implications for paste backfill design, tailings storage stability and metal recovery circuits.

American Rare Earths’ Halleck Creek project in Wyoming has secured a Seed Translational Acceleration of Research (STAR) award via the University of Wyoming’s NSF Accelerating Research Translation programme to study byproducts and tailings from rare earth extraction. The work, led by Tyler Brown at UW’s School of Energy Resources, will assess technical viability, processing requirements and end-use applications for these materials and their impact on project economics. Halleck Creek metallurgical tests have already upgraded ore from 0.34% to 3.72% TREO, removing 93.5% of non-rare earth material early so only 6.5% requires further refining.
