Halleck Creek Rare Earths Project

under development

The Halleck Creek project is a rare earths mining and processing project located in Platte and Albany Counties, Wyoming. It hosts the largest known deposit of total contained rare earth oxides in the United States and aims to develop a large-scale, strategically important rare earths project with onsite mineral processing and separation facilities. The project is positioned to reduce U.S. reliance on imports and support critical supply chains for advanced manufacturing, defense, and future technologies.
