The event included presentations by Dr. Geraldine Richmond, Department of Energy (DOE) Undersecretary for Science and Innovation, and Senator John Barrasso (R-Wyo.).

“During this critical time as the U.S. works to advance a domestic rare earth supply chain, I am pleased to be presenting in multiple venues in the coming weeks,” Mr. Berg stated. “Rare Element Resources is poised to become a cornerstone for a secure, domestic supply of the critical magnet materials essential to so many hi-tech and green technologies. Attending these events will allow me to highlight our progress.”

Mr. Berg added, “The Company has been working, along with our strategic partner, General Atomics, to advance our demonstration project to confirm the advantages of our proprietary rare earth recovery and separation technology. Data generated from the demonstration plant will be used in an economic evaluation and the design of a full-size commercial plant for processing material from the Bear Lodge Project, as well as to validate the cost and environmental benefits of the process over traditional recovery methods. With timely permitting and licensing, we are looking to commence construction of the plant in the second half of 2023 and for operations to begin in mid-2024.”
