Rare Element collects bulk sample for pilot plant test

RARE ELEMENT REPORTS COLLECTION OF BULK SAMPLE FOR PROPOSED PILOT PLANT TEST

Rare Element Resources Ltd. has completed a bulk sample collection program at the company's 100-per-cent-owned Bear Lodge rare earth element (REE) and gold property, located in northeastern Wyoming. The objective of the program was the acquisition of about eight tons or more of oxidized, REE mineralized FMR vein material that will be used to feed a proposed pilot plant designed to test the commercial viability of the mineral process flowsheet developed for the REEs by Mountain States Research and Development International, the company's metallurgical testing consultants. A second purpose for the test is to produce a bulk mixed rare earth concentrate that can be used for marketing if the company decides to sell concentrates initially, possibly as a first step toward eventual individual rare earth oxide separation and sale. Several laboratories with pilot plant capabilities are under consideration for the testing. The pilot plant test will be part of a preliminary feasibility study planned for completion in late 2011.

The term FMR refers to the major constituents of the highly oxidized and leached, former carbonatite dikes that occur in the depth range from the surface to 300 to 500 feet beneath the surface -- FeOx (iron oxides), MnOx (manganese oxides) and REE minerals. The original carbonatite dikes contained high abundances of both REE and sulphides. Oxidation of the sulphides resulted in the leaching of nearly all matrix carbonates and formed residual FMR, which generally contains only bastnasite-group rare earth minerals as the residual carbonates. FMR mineralization is a loose and friable material with a clay-like consistency that disaggregates easily.

The bulk testing program consisted of a series of large-diameter PQ (diameter 85 millimetres) and HQ (diameter 63.5 mm) core holes that penetrated the oxide zone in the Bull Hill Southwest REE deposit. The holes were drilled from closely spaced sites in each of two areas (9-F and 9-A) where the FMR vein material occurs very close to the surface. Drilling was designed to collect samples that would be representative of material sent to the mill during the first five years of potential production. The deepest holes were drilled to a depth of approximately 190 feet (58 metres). The areas sampled by these methods were located in the northwestern and southeastern parts of the deposit. Grades are likely to range between 2 per cent and 15 per cent rare earth oxide, based on previous exploration holes from the same sites. Multiple holes were drilled from each site in fans at a common azimuth and different inclination angles designed to capture as much FMR as possible. A total of 40 holes were drilled, with an aggregate footage of 2,117 feet (645 metres) of REE mineralized FMR material. Thirty of the drill holes are PQ-size holes for a total footage of 1,753 feet (534 metres) of FMR material, and 10 of the holes are HQ-size, with a total footage of 364 feet (111 metres) of FMR material. The aggregate weight of REE mineralized material collected from the drilling program is about 14,000 pounds (6,364 kilograms).

The drill core will be augmented by bulk FMR sample material collected from a shallow trench excavated in a drill site in the northwestern part of the Bull Hill Southwest deposit, near site 9-F. There are approximately 3,500 pounds (1,591 kilograms) of FMR material from the trench collected in several 55 gallon drums. The company has stockpiled a total of approximately 8.8 tons (eight tonnes) of FMR material at its core storage facility in Sundance, Wyo. This material will be retained there until the testing laboratory is selected and the pilot plant is built and ready for operation. The program has acquired sufficient FMR feed material required for the pilot plant study.
