Lakewood, Colorado - Rare Element Resources Ltd. (NYSE Amex: REE; TSX: RES) is pleased to announce rare earth element (REE) and gold assay results from 29 additional drill holes that were completed during the 2011 core drilling program at the Company's 100% owned Bear Lodge property, located in northeastern Wyoming, USA.
- Confirms Previously Reported HREE-Enrichment Targets
Lakewood, Colorado - Rare Element Resources Ltd. (NYSE Amex: REE; TSX: RES) is pleased to announce rare earth element (REE) and gold assay results from 29 additional drill holes that were completed during the 2011 core drilling program at the Company's 100% owned Bear Lodge property, located in northeastern Wyoming, USA. These results include 15 drill holes from the Bull Hill resource area, six drill holes from the Whitetail Ridge area, four drill holes from the East Taylor target area, and four drill holes from the Carbon target area. Three drill holes from the 2011 program remain to be assayed.
Dr. Jim Clark, Vice President of Exploration for the Company stated, "Our 2011 drilling results confirm the continuity of the mineralized bodies, and we have continued to significantly expand the resource. We are excited about the prospect of delineating another resource that exhibits the potential for higher grades of HREE at Whitetail Ridge, East Taylor and Carbon. We feel that the district has tremendous upside potential."
The RE mineralization intersected in the 29 drill holes is contained primarily within the near-surface oxidized (FMR) in fully oxidized but incompletely leached equivalents of carbonatite dikes (oxide carbonate/OxCa). These dikes are widespread in the district and concentrated in dike swarms and stockwork zones on the Bull Hill, Bull Hill West, Whitetail Ridge, East Taylor and Carbon resource and target areas (Figure 1). Overlapping gold mineralization in the Whitetail Ridge, East Taylor and Carbon areas is contained in the FMR and OxCa dikes and stockwork, and in the alkali silicate host rocks. FMR refers to the major constituents of the highly oxidized, former carbonatite dikes that occur in a depth range from surface to 300-500ft/91-152m beneath the surface---F(FeOx)-M(MnOx)-R(REE minerals) (FMR).
Bull Hill Resource Area (now includes Bull Hill West)
Highlights from the Bull Hill area drill holes are summarized below.
Eight of the 15 holes in the Bull Hill Resource Area were drilled along a prescribed NE-SW grid at azimuths of 045° and 225°. Holes were also drilled along azimuths of 090° (one hole), 270° (two holes), and 270° (four holes) in order to test for mineralized bodies directed along structures divergent from the main trend of mineralization (Figure 1).
Whitetail Ridge Resource Area
RE mineralization in and adjacent to the Whitetail Ridge Resource Area occurs dominantly NW-trending dikes, veins and stockwork zones. The six holes were drilled along a prescribed NE-SW grid at azimuths of 045° or 225°. The highlights from the Whitetail Ridge area drill holes are summarized in the following table. Two of the drill holes contain significant intercepts of gold mineralization hosted in FMR stockwork and diatreme breccia.
East Taylor Target Area
The East Taylor target is located approximately 2,500ft/760m west of the main Bull Hill RE deposit and 2,500ft/760m southwest of the Whitetail Ridge deposit (Figure 1). The zone appears to have an easterly strike, as opposed to the dominant northwesterly and northerly mineralized structures in the Bull Hill-Whitetail Ridge deposits. Preliminary geological mapping and projection of FMR intercepts in drill holes suggest that the REE mineralization consists of dikes and adjacent stockwork with dimensions of more than 700ft/210m east-west by 250ft/75m north-south, and the mineralization is open to the east. Results from six core drill holes drilled at the East Taylor target area are reported here and augment the results from the three core holes reported in a 4 August 2011 press release. The core holes were drilled to follow up results from reverse circulation drill hole SUN-090. This hole was collared east of Taylor Ridge during the 2010 gold drilling program and intersected significant FMR-style mineralization strongly enriched in both light and heavy REE (see press release dated 27 October 2011. The REE mineralization is associated with coincident and peripheral zones of gold mineralization, and the gold assay results are also reported here.
Carbon Target Area
The Carbon REE target is located approximately 1,200 ft/370m northwest of the Whitetail Ridge deposit along an apparent northwest-trending zone of mineralization (Figure 1). Two reverse-circulation drill holes (SUN-076 and SUN-079) were completed during the 2010 Sundance gold exploration program and cut significant REE mineralization in FMR and unoxidized carbonatite vein material (see news release dated 4 August 2011). The REE mineralization may portend the northwestern extension of the Whitetail Ridge system or, alternatively, a distinct FMR/carbonatite mineralized system. Significant REE-bearing intercepts from the Carbon target area are summarized below. If this mineralization is a continuation of the Whitetail Ridge dike system and the Bull Hill SW system, it may strike up to 5,000ft/1,500m in length. The Carbon target exhibits enrichment in both light and heavy REEs.
Heavy Rare Earth Enrichment
In 2011, the Company identified significant HREE enrichment in FMR and oxide-carbonate carbonatite dikes at the Whitetail Ridge resource area and the East Taylor and Carbon target areas (see news releases dated 4 August and 27 October 2011). The assay results reported here confirm those observations. Preliminary mineralogical studies indicate that the Y-HREE (yttrium-heavy rare earth element) mineralization is found primarily in the RE fluocarbonates, synchysite and parasite, at Whitetail Ridge and Carbon, and in xenotime, and yttrium-vanadiam phosphate, and RE fluocarbonates at East Taylor. Individual RE assays for Eu, Tb, Dy and Y in intercepts greater than 20ft/6.1m from drill holes reported here are summarized below. Values from the Bull Hill Measured and Indicated resource is included for comparison.
The grades for Eu, Tb, Dy and Y are among the highest of any North American REE deposit.
REE assay values are reported by convention as the combined oxide equivalents (REO) of the 15 elements in the lanthanide series plus yttrium. The Bull Hill deposits at the Bear Lodge project contain predominately the light REEs (lanthanum, cerium, praseodymium, neodymium and samarium), with economically important quantities of several of the heavy REEs (europium, dysprosium and terbium). The Whitetail Ridge Resource area and the East Taylor and Carbon target areas have more abundant HREE enrichment, with enhanced abundances of Eu, Dy, Tb and Y (see news release dated 4 August 2011).

Mineral Resources are not Reserves
Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for minability, selectivity, mining loss, and dilution. These mineral resource estimates are in the measured, indicated, and inferred mineral resource categories. Inferred mineral resources are normally considered too speculative geologically for the application of economic considerations that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated mineral resource categories through further drilling, or into mineral reserves once economic considerations are applied.
