HALIFAX, NOVA SCOTIA–(Marketwired – June 7, 2016) – Ucore Rare Metals, Inc. (TSX VENTURE:UCU)(OTCQX:UURAF) (“Ucore” or the “Company”) is pleased to update on the continuing performance of the SuperLig®-One rare earth element (“REE”) separation pilot plant (the “Plant” or “SuperLig®-One”.)
Pregnant leach solution (“PLS”) derived from the Company’s Bokan-Dotson Ridge project in Alaska has been treated by the SuperLig®-One Molecular Recognition Technology (“MRT”) Plant, at the IBC Advanced Technologies, Inc. (“IBC”) Utah facility. The PLS was initially separated from impurity metals (“Gangue Metals”) (see Ucore Press Release (“PR”), dated May 9, 2016) followed by the removal of scandium (see Ucore PR dated May 24, 2016.)
In the latest separation circuit, the PLS has now been separated into two classes of REE: heavy REE, comprised of samarium to lutetium (“HREE”) and light REE, comprised of lanthanum to neodymium plus yttrium (“LREE”). The class separations have been achieved at 99%+ purity and 99%+ recovery.
The foregoing represents the final stage of processing prior to the separation of individual Critical HREE (“Heavy CREOs”) from the remaining PLS. The Heavy CREOs, which include dysprosium, terbium and europium, are classified by the US Department of Energy as being critically important to the near term viability of domestic clean energy applications and industries.
“The SuperLig®-One pilot facility has again delivered results that represent near quantitative levels of recovery and purity,” said Jim McKenzie, President and CEO of Ucore. “This ability differentiates MRT from less selective technologies such as solvent extraction, ion exchange, and precipitation (“Legacy Separation Technologies”), which consume significant quantities of solvents and hazardous chemicals. These legacy methodologies are also characterized by substantial waste generation, much of it in the form of unrecoverable REE. SuperLig®-One, by contrast, is the first commercial scale green chemistry platform that we are aware of capable of separating and recovering HREE and LREE classes at both a 99%+ level of purity and a 99%+ level of recovery.”
Since announcement of the completion of SuperLig® certifications; PLS analysis; automation control verification; water testing; process flow testing of the Plant; REE separation, as a group, from the Gangue Metals; and scandium separation from the group of REE; the following results have been achieved using the SuperLig®-One Plant:
The SuperLig®-One Plant offers a disruptive technology platform for diversifying, from commercial, geographical and technological perspectives, the separation and processing of REE. Currently concentrated in China, present-day REE processing is oligopolistic and depends upon an installed base of Legacy Separation Technologies. The introduction of efficient, innovative, green chemistry REE production using MRT is expected to substantially alter this dynamic and strengthen the domestic, commercial, and military economies of the United States and other nations that depend on reliable and efficiently processed sources of rare metals, such as REE, for an environmentally sustainable and prosperous future.
The next stages of the SuperLig®-One Plant operation will demonstrate the separation of the individual Heavy CREOs, as well as two HREE sub-groups, as follows:
The recently separated 99%+ pure LREE class will be retained for future separations, as required.
Following confirmatory testing of each unit operation, the Plant will undergo a continuous run of PLS.

Ucore Rare Metals is a development-phase company focused on rare metals resources, extraction and beneficiation technologies with near term potential for production, growth and scalability. On March 3, 2015, Ucore announced the right to acquire a controlling ownership interest in the exclusive rights to IBC SuperLig® technology for rare earths and multi-metallic tailings processing applications in North America and associated world markets. The Company has a 100% ownership stake in the Bokan project. On March 31, 2014, Ucore announced the unanimous support of the Alaska State Legislature for the investment of up to USD $145 Million in the Bokan project at the discretion of the Alaska Import Development and Export Agency (“AIDEA”).

MRT is at advanced testing stages and has yet to be proven, at a commercial scale, for the separation of rare earth elements. The Company has not yet released an economic assessment on the use of MRT for the separation of rare earth elements and does not yet have any specific contracts for the processing of rare earths using MRT.
