-- Results confirm: -- High abundances of Critical Rare Earth Elements (CREEs) which include Nd, Pr, Eu, Tb, Dy and Y in all deposits -- Heavy Rare Earth (HREE)-enrichment at Whitetail and Carbon -- Continuity and grade of the Bull Hill deposit
Rare Element Resources Ltd. (NYSE Amex: REE)(NYSE MKT: REE)(TSX: RES) (the "Company") is pleased to announce rare earth element (REE) assay results from the final core holes completed during the 2012 drilling program at the Company's 100% owned Bear Lodge property, located in northeastern Wyoming, USA. The drilling results confirm that the Bear Lodge deposits contain high grades of total rare earth oxide (TREO), including high abundances of combined Critical Rare Earth Oxides (CREOs).
Dr. James Clark, Vice President of Exploration for Rare Element Resources, states, "Assay results are now in from all of the development and exploration core holes drilled during our 2012 program. We are extremely pleased with the results as most recent drill results confirm and further expand the quality and continuity of the Bull Hill REE deposit and the Whitetail Ridge resource area. We expect to significantly increase the Measured and Indicated resources in those deposits in preparation for the upcoming definitive Feasibility Study (dFS). Further, the results confirm the zones of HREE-enrichment (Eu, Tb, Dy, and Y) at Whitetail Ridge and Carbon and illustrate the significance of this world class source of CREOs."
Critical Rare Earth Oxides (CREO)
Critical rare earth elements (CREEs) are those with the highest value, and for which the strongest future growth is projected. We refer here to the oxides of Nd, Pr, Eu, Tb, Dy, and Y as Critical Rare Earth Oxides (CREO). In 2011, the Company identified significant HREEs (Eu, Tb, Dy, and Y) in leached FMR (F (FeOx)- M (MnOx)-R (REE minerals)) and oxide-carbonate dikes at the Whitetail Ridge resource area, and at the East Taylor and Carbon target areas (see news releases dated 4 August and 27 October 2011, and 10 December 2012). The current set of assay results from the Whitetail Ridge resource area and Carbon target confirm those important observations. Examination of aggregate significant intercepts from past drill results and the current set of drill assay results indicate that there is a district-wide zonation in which the strongest TREO enrichment occurs within a central zone focused on the Bull Hill and Bull Hill Northwest deposits, while the strongest HREE (Eu, Tb, Dy and Y) enrichment is found in mineralization peripheral to the central zone and focused at the Whitetail Ridge deposit, and at the Carbon and Taylor REE target areas (Table 1 and Figure 2). The peripheral enrichment zone is ascribed to a late-stage, low-temperature hydrothermal event.
Objectives of the 2012 Drill Program
The objectives of the 2012 drilling program were to expand and upgrade the district's resource categories at the Bull Hill and Whitetail Ridge oxide deposits, and to further delineate the HREE (Eu, Tb, Dy, and Y) enrichment at the Whitetail Ridge resource area and Carbon target area. The drill results emphasize a Bear Lodge district-wide REE zonation, with a central zone of strong TREO enrichment that gives way to a peripheral zone with significant TREO and strong Eu, Tb, Dy, and Y enrichment.
