Ucore Rare Metals Inc. (TSXV: UCU | OTCQX: UURAF) announced on November 9, 2026 that it has received more than 50 tonnes of mixed rare earth carbonate at its Louisiana Strategic Metals Complex, marking a key commissioning milestone for RapidSX™ Machine A. The bastnaesite-derived feedstock originates from a North American rare earth element source — the same material used to produce 99.5% NdPr oxide at Ucore's Kingston, Ontario Commercialization and Demonstration Facility in August 2026. The announcement signals meaningful progress toward the company's target of supplying medium and heavy rare earth oxides to Western markets.

Key Points

  • Ucore Rare Metals Inc. (TSXV: UCU | OTCQX: UURAF), headquartered in Halifax, Nova Scotia
  • 50+ tonnes of mixed rare earth carbonate commissioning feedstock received at the Louisiana SMC for RapidSX™ Machine A
  • Machine A comprises 125 solvent extraction chemistry stages with 600 tonnes per annum of total rare earth oxide processing capacity; Enhanced Machine A commissioning targeted for H1 2027
  • Investors may be watching progress on Factory Acceptance Testing optimisation and the planned addition of a Western-sourced samarium, europium, and gadolinium feedstock

Commissioning Feedstock Arrives at Alexandria, Louisiana Facility

The release states that the mixed rare earth carbonate delivered to the Louisiana SMC is bastnaesite-derived and sourced from North America. Ucore notes this is the identical "second source" feed material used at its Kingston, Ontario RapidSX™ Commercialization and Demonstration Facility, where the company produced 99.5% NdPr oxide in August 2026. A planned Western-sourced samarium, europium, and gadolinium mixed rare earth carbonate is also expected to form part of the commissioning feedstock program, though timing details for that material were not disclosed in the announcement.

Factory Acceptance Testing Progress and Machine A Engineering Configuration

Under the Factory Acceptance Testing program at the Kingston CDF, Ucore has validated the configuration of primary Machine A components. Each of the 125 solvent extraction chemistry stages consists of two automated 8-inch RapidSX™ contactor columns feeding a single 12-inch separator column. The company states it is continuing to optimise minor component connectivity details. Machine A is designed to process 600 tonnes per annum of total rare earth oxide throughput and can operate either as two machines in series for NdPr production or as a single 125-stage machine producing simultaneous product outputs including samarium, gadolinium, terbium, and dysprosium.

Strategic Rationale: Addressing Chinese Export Restrictions on Critical Rare Earths

The release highlights that Machine A is specifically designed to address Chinese licensing restrictions on samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium implemented in April 2025, which the company states remain in effect. Ucore's COO is quoted in the announcement stating the company is "readying to supply medium and heavy rare earth oxides to the West in 2027." The disclosure suggests the SMC is positioned to support North American rare earth supply chain resilience, though commercial outcomes remain subject to numerous conditions outlined in the company's forward-looking statements.
