TSX-V: RES & AMEX: REE

VANCOUVER, April 6 /CNW/ - Rare Element Resources Ltd. (TSXV: RES) (AMEX: REE) is pleased to announce the final rare earth element (REE) assay results from the last fifteen drill holes completed during its 2010 core drilling program at the Company's 100% owned Bear Lodge property, located in northeastern Wyoming, USA (Figure 1 - http://files.newswire.ca/675/Rare_Element_Bear_Lodge.pdf). The current results are from the Bull Hill Southwest resource area (six core holes), the Bull Hill NW resource area (seven core holes), and a Conceptual Carbonatite Plug target area west of Bull Hill (two core holes). Results of REE assays from a 2009 hole, which was recently analyzed, in the Bull Hill SW area are also summarized.  An NI 43-101-compliant resource estimate for the Bull Hill SW and Bull Hill NW resource areas was completed in May 2010, and the complete results from the 2010 drilling program will be incorporated into an updated NI 43-101 compliant resource model scheduled for release during the second quarter of 2011. The objectives of the 2010 drilling program were to expand the Bull Hill SW oxide resource and upgrade the resource category, and to explore for additional REE resources at the Bull Hill NW and Whitetail Ridge target areas. Previous assay results from the Bull Hill SW resource area, Bull Hill NW resource area, the Whitetail Ridge REE target area, and a new target area northwest of Whitetail Ridge were reported in a series of news releases dated 15 September and 9 November 2010, and 10 January and 7 February 2011.

Highlights from the current group of assays include the following intercepts:

Jim Clark, Vice President of Exploration states: "Taken as a whole, the 2010 drilling program was tremendously successful, and this last batch of assay results emphasizes that success. The results continue to demonstrate the continuity of the mineralized bodies and show that the Bull Hill SW deposit is open to the southeast along strike and down-dip. The Bull Hill SW dike swarm exhibits excellent grade over significant widths. The results from drill holes RES10-51 and RES10-57 suggest that the dike swarm may continue west of the Bull Hill drainage, a zone interpreted previously as a fault (West Bull Hill fault), and open a new area of concentration for the 2011 drill program. The specific structural controls for REE mineralization in the Bull Hill NW resource area remain elusive and another focus for the Company's 2011 drilling. Our interest in Bull Hill NW is also piqued by the intercept of significant gold mineralization in drill hole RES10-60, where the highest grade (12 ft @ 11.85 gpt Au) is contained within a silicocarbonatite dike. We expect 2011 to be another exciting year for the Company as we advance the Bear Lodge project."

Drilling Results

The REE deposits in the Bear Lodge Mountains of northeastern Wyoming occur within a large alkaline igneous complex that domes overlying older  sedimentary rocks. The REE mineralization is hosted in dike and veinform carbonatitic intrusive bodies and their near-surface oxidized equivalents (FMR). FMR refers to the major constituents of the highly oxidized, former carbonatite dikes that occur in the depth range between the surface and 300-500 feet (91 - 152 meters) beneath the surface- F (FeOx)-M (MnOx)-R (REE minerals). The FMR bodies contain little or no matrix calcite. A zone of variably oxidized carbonatite with minor to significant matrix calcite is termed transitional carbonatite. This zone has uneven thickness and occurs beneath the FMR zone and above the deeper zone of unoxidized carbonatite.

REE assay values are reported by convention as the combined oxide equivalents (REO) of the fifteen elements in the lanthanide series + yttrium. The oxide equivalents are approximately 15.6% higher than the combined metal assay values. The Bear Lodge project contains predominantly the "light" REE (lanthanum, cerium, praseodymium, and neodymium), and economically important quantities of several of the "heavy" REE (europium, dysprosium, and terbium).

Bull Hill SW Resource Area

REE mineralization in the Bull Hill SW resource area is contained within intrusive dikes, veins, and stockwork of FMR, transitional carbonatite, and carbonatite that invade heterolithic intrusive breccia of the Bull Hill diatreme. Stockwork refers to a rock cut by a network of small veins or dikes that contain the mineralization. Most of the REE mineralization in the current set of drill holes occurs within FMR dikes and veins.

Six of the seven holes reported here were drilled along a bearing of N45ºE from a series of sites on a resource evaluation grid established for the Bull Hill SW deposit in conjunction with Ore Reserves Engineering, the Company's resource estimation consultant (Figure 1 - http://files.newswire.ca/675/Rare_Element_Bear_Lodge.pdf). One hole was drilled on the grid along a bearing of S45ºW. The bearing, inclination, and significant assay intercepts from the REE-mineralized sections for each of the drill holes are summarized in Table 1 below.

Table 1. Summary of new REE-mineralized drill intercepts at the Bull Hill SW Resource Area:

Drill hole RES09-19 (N45E, -45º; total depth 215 feet)

* Note: Drill hole RES09-19 was left open at the end of the 2009 field season for completion in 2010. It was decided in 2010 not to re-enter the hole. Hence assays were performed in 2010.

Drill hole RES10-44 (N45E, -60º; total depth 510.5 feet)

Drill hole RES10-45 (N45E, -45º; total depth 490 feet)

Drill hole RES10-46 (N45E, -45º; total depth 580 feet)

Drill hole RES10-47 (N45E, -70º; total depth 752 feet)

Drill hole RES10-49 (N45E, -45º; total depth 510 feet)

Drill hole RES10-50 (S45W, -45º; total depth 449 feet)

Drilling results confirm that the target FMR and carbonatite bodies exhibit strong REE mineralization over a strike length of more than 1400 feet (426m). Interpretive correlations of drill intercepts suggest a structural bias toward vertical or near vertical dips and a transitional change in strike from northwesterly to almost due north in the northern part of the resource area. The results from drill holes RES10-46, RES10-47, and RES10-57 suggest that mineralized veins, dikes, and associated stockwork zones continue to the west across the Bull Hill drainage with little or no offset. Until these recent results from deep drilling west of the drainage, it was thought that the drainage represented a structure (West Bull Hill fault) that significantly offset or terminated the REE-mineralized dike swarms at the Bull Hill SW resource area.

Bull Hill Northwest Resource Area

REE mineralization in the Bull Hill NW resource area is contained within intrusive dikes, veins, and stockwork of FMR, transitional carbonatite/silicocarbonatite, and carbonatite/silicocarbonatite that invade trachytic and phonolitic intrusive rocks of the Bear Lodge alkaline complex. Silicocarbonatite is a carbonatite-related rock that carries abundant silicate mineral phases dispersed in the carbonate matrix, in this case primarily biotite and K feldspar. Significant results from the current set of drill holes in the Bull Hill NW resource/target area are reported in Table 2.

Table 2. Summary of new REE-mineralized drill intercepts in the Bull Hill NW Resource Area:

Drill hole RES10-52 (N90W, -60º; total depth 687 feet)

Drill hole RES10-53 (N90W, -45º; total depth 506 feet)

No significant results.

Drill hole RES10-54 (N90W, -70º; total depth 668 feet)

Drill hole RES10-55 (N90E, -45º; total depth 685 feet)

Drill hole RES10-59 (N90W, -45º; total depth 535 feet)

Drill hole RES10-60 (N90W, -70º; total depth 897 feet)

Drill hole RES10-61 (N45W, -45º; total depth 322 feet)

No significant results.

The results from the Bull Hill NW drill holes show significant REE mineralization in FMR/carbonatite/silicocarbonatite dikes and stockwork. The structural controls for the mineralized bodies remain incompletely understood in the target area. The strongly anomalous gold mineralization in drill hole RES10-60 is distributed in trachyte porphyry and crosscutting biotite silicocarbonatite dikes, with the highest-grade intercept (12 ft @ 11.85gpt Au) contained within a biotite silicocarbonate dike. This occurrence of overlapping gold and REE mineralization will be investigated during the Company's 2011 exploration program.

Conceptual Carbonatite Plug Target Area

Initial geological interpretation of the Bull Hill SW dike swarm suggested that the REE-mineralized bodies were truncated against an inferred fault that appeared to run along the drainage west of Bull Hill (West Bull Hill fault). However, 2010 drill results from S45W trending holes that cut across the inferred fault zone, and the current results from drill holes RES10-51 and RES10-57, both collared west of the drainage/fault, indicate that significant REE mineralization is present in the area west of the Bull Hill drainage. The area was also identified for potential to host a deep carbonatite plug at depth. This interpretation was based on the presence of strong stockwork REE mineralization in FMR and carbonatite veins intersected in historic drilling by Molycorp and Hecla Mining Company, and by a coincident IP/resistivity anomaly that suggests the presence of abundant sulfide minerals at depths greater than 500 feet. Carbonatite bodies represent the most sulfide-rich lithologies in the district. Significant results from two exploration holes in the Conceptual Carbonatite Plug target area are reported in Table 3 below.

Table 3. Summary of new REE-mineralized drill intercepts in the Conceptual Carbonatite Plug Target Area:

Drill hole RES10-51 (S45W, -70º; total depth 680 feet)

Drill hole RES10-57 (S45W, -80º; total depth 1675 feet)

The data illustrate that significant REE mineralization is present in FMR and carbonatite dikes, veins, and stockwork zones west of the Bull Hill drainage, and that there may little or no offset of mineralized bodies across the structure inferred along the drainage west of Bull Hill. These results open up a large area west of Bull Hill for prospective REE mineralization.

Assaying and Quality Control

ALS Chemex conducted the assaying for the rare earth elements in their Vancouver, British Columbia assay facility. ALS Chemex Vancouver is accredited to ISO 9001 and operates according to ALS Group standards consistent with ISO 17025 methods at other laboratories. The samples were prepared and subjected to lithium metaborate fusion, followed by ICP analysis and a mass spectroscopy finish.

Analytical quality is monitored through the use of randomly inserted quality control samples, including standards, blanks, and duplicates, which are blinded to the analytical laboratory. Results of the analyses at ALS Chemex are evaluated continuously by Dr Jeffrey Jaacks, the Company's QA/QC consultant, who is a Qualified Person according to National Instrument 43-101. The results from the current data set indicate acceptable accuracy and precision. Blank analyses also indicate no issues with carry-over contamination.

Correction to News Release Dated 7 February 2011 "Rare Element Reports Additional REE Assays From Resource Areas and a New Target Area"

Rare Element notes that there were omissions and typographical errors in the section of the news release dated 7 February 2011 titled "Potential New Target Area". The assay summary in Table 3 should be amended as follows:

Table 3. Summary of REE-mineralized intercepts in reverse circulation drill holes from the 2010 Sundance gold exploration project:

Drill Hole SUN-076 (N45W, -45º; total depth 615 feet)

Drill Hole SUN-079 (S80W, -45º; total depth 775 feet)

The amended assay table does not change the conclusion that the new target area northwest of the Whitetail Ridge target area represents another promising exploration area for the Bear Lodge project.

Rare Element Resources Ltd (TSX-V: RES: AMEX: REE) is a publicly traded mineral resource company focused on exploration and development of rare-earth elements and gold on the Bear Lodge property.
