Nov 16, 2015 – HALIFAX, NOVA SCOTIA – Ucore Rare Metals Inc. (TSXV:UCU) (OTCQX:UURAF) (“Ucore” or the “Company”) is pleased to update on the design and construction of the SuperLig®1 rare earth separation pilot plant (the “Plant”). The initial purpose of the Plant is to confirm the effectiveness of Molecular Recognition Technology (“MRT”) in the separation of rare earth elements (“REE’s”) at bulk scale and at the high purities previously achieved at bench scale utilizing feedstock derived from the Company’s Bokan-Dotson Ridge (“Bokan”) deposit in Southeast Alaska (see Ucore Press Release: March 02,2015). Subsequent to this, the Plant will be utilized to confirm the effectiveness of SuperLig® technology in separating REE’s from a variety of feedstock sources in North America and beyond. Completion of construction, and the commencement of initial testing, is anticipated to take place in early 2016.
Ucore has contracted with IBC Advanced Technologies, Inc. of American Fork, Utah (“IBC”) for the design, construction, and operation of the Plant (see Ucore Press Release: July 08, 2015). The facility will be initially located in American Fork, Utah, in proximity to the IBC Research and Development Facility (“RDF”). The Plant will also be designed for breakdown and shipping to third party test locations, as and when required.

“This is a significant Pilot Plant, with a total capital outlay in excess of USD $3 million and a footprint anticipated to occupy the approximate space of a few tractor trailers,” said Jim McKenzie, President and CEO of Ucore. “SuperLig®1 will be the first of its kind, as an MRT plant dedicated to the separation and refining of REE’s and associated valuable metals. The facility will be fully modular in design, with the ability to install larger or smaller columns and customized SuperLig® substrate as required, depending on the skew and the quantity of the feedstock being tested.”
“The new Plant will be capable of accepting mixed concentrates from a variety of feedstock sources,” said Ken Collison, COO of Ucore. “This means that SuperLig®1 will be capable of accepting REE mixed concentrates not just from Bastnaesite, Monazite and Xenotime- based deposits the world over, but from a wide range of tailings and process-flow facilities as well. Our overriding objective is to offer a flexible platform for the handling of mixed concentrates from multiple points of origin, running successive batch processes quickly and efficiently, and reconfiguring for new input product with minimal turnaround. What’s more, the Plant will be capable of refining non-REE metals as required, including PGM’s, scandium and numerous other specialty metals.”
The Plant design-build process is progressing under the supervision of multiple work teams within the IBC RDF. Laboratory scale work has been completed to refine the process for the separation of high priority rare earths, with the objective of replicating the 99%+ purity levels previously achieved through bench work. The system workflow has been defined and a comprehensive flowsheet for pilot scale processing has been developed. Long-lead time chemical compounds for the production of SuperLig® products have been ordered, and the manufacture of SuperLig® resins for use in the Plant has commenced. Engineering for the Plant is now in progress, with the majority of equipment and specialized components now either sourced or on short order.
The initial test run of the Plant will utilize a bulk mixed concentrate derived from the Bokan deposit. The Bokan test work will take place in two stages. Phase 1 will target the separation of the Critical Heavy REEs (“CREEs”), being Dy, Tb, and Eu. Phase 2 will be completed to establish the ability to separate an additional 8 rare earth elements. Select REE’s for which there is a limited market, such as Ho through to Lu on the periodic table, will be separated on a pilot scale at a future date if deemed appropriate. It is expected that the plant will operate at a flow rate in the range of 160 liters of pregnant leach solution (“PLS”) per day, capable of generating multiple kilograms of REEs, as separated rare earth carbonates, per week based on Bokan feedstock. As part of the modular design, the Plant will be reconfigurable and upgradeable, with the capability of accepting a wide range of feedstock from alternate sources, and of expanding the initial flow rate.
