Rare Element Resources Ltd. provided an update on the progress of its planned rare earth processing and separation demonstration project in Upton, Wyoming. The project, led by General Atomics, an affiliate of the Company's largest shareholder Synchron, has just completed the 60% plant design milestone and is now advancing toward final detailed engineering due for completion later this year. Early expenditures for acquisition of long lead-time equipment and services are being made to minimize the effect of inflation and supply chain bottlenecks, and permitting and licensing activities are also underway.

These activities are taking place while the previously leased plant location in Upton, Wyoming is being prepared for construction by the site owner. The demonstration plant will utilize the Company's proprietary processing and separation technology, which is a closed-cycle process with fewer steps, resulting in expected attendant environmental benefits and lower costs compared with current technologies. The plant is expected to produce a commercial-grade neodymium/praseodymium (Nd/Pr) rare earth high- purity oxide that is used in producing high-strength permanent magnets.

These high-strength permanent magnets are a key component in the manufacture of electric vehicles and wind turbines, among other technology uses. The demonstration plant will process already stockpiled sample material from the Company's Bear Lodge Project located in northeastern Wyoming. The Company anticipates that the demonstration plant's design will be complete by the end of 2022, followed by the completion of permitting activities in the second quarter of 2023 and the completion of the plant's construction within a period of 12 months thereafter.

Operations to process and separate the rare earth elements from the stockpiled sample will follow for an additional 8-to-12-month period. The total estimated timeline for the project is approximately 40 months, which began in October 2021.
