Rare Element Resources Ltd. ("the Company") (TSXV:"RES") is pleased to announce 2009 REE assay results from five drill holes that explored the Bull Hill Northwest target area (Figure 1). The Bull Hill NW target was identified on the basis of Hecla Mining Company's drill Hole WP-2, drilled in 1987.
Hole RES09-8 containing an estimated aggregate true thickness of 213.4 feet at an average assay grade of 5.54% REO
Rare Element Resources Ltd. ("the Company") (TSXV:"RES") is pleased to announce 2009 REE assay results from five drill holes that explored the Bull Hill Northwest target area (Figure 1). The Bull Hill NW target was identified on the basis of Hecla Mining Company's drill Hole WP-2, drilled in 1987. Historic drill hole WP-2 intersected 186 feet assaying 9.56% rare earth oxides (REO) from the depth interval 23 -- 209 feet (estimated true thickness = 40.5') and 80 feet assaying 5.65% REO in the depth interval 1170 -- 1250 feet (estimated true thickness = 45.9'). During the 2009 program the Company drilled five holes aggregating 5,141 feet in the area of the target. The objectives of the exploration drilling were:
-
Offset the high-grade mineralized bodies intersected in historic drill hole WP-2.
-
Determine whether the WP-2 dikes are part of the NW-trending Bull Hill SW resource area dike sets, or if they are representative of a new REE-mineralized system.
-
Determine the definitive structural orientation and mineralization controls of REE mineralization in the Bull Hill NW target area.

*FMR is defined as oxide material having FeOx + MnOx + REE as the principal components. FMR is the near-surface oxidized equivalent of carbonatite dikes that occur at depth in the unoxidized zone.
The 2009 drilling data from the Bull Hill NW target area indicate that the REE-mineralized bodies do not represent the extension of the Bull Hill SW resource area carbonatite/FMR dike sets. Rather, they appear to represent a discrete set of carbonatite/FMR veins and dikes whose emplacement may be controlled by a NE-trending fault zone along the Whitetail Creek drainage or which may represent a separate new REE system within and north of the fault.
Dr. James Clark, Rare Element Resources' VP Exploration states, "We are excited about the results from drill hole RES09-8, because it complements drill results from the historic Hecla WP-2 drill hole and indicates that the Bull Hill NW target area may harbor a significant new REE resource, open to the north and with excellent possibilities for higher-grade material. An important part of the 2009 exploration drilling program will focus on understanding the controls, orientation, and extent of the mineralization, and delineation of a potential associated REE resource."
Activation Laboratories (ActLabs) conducted the rare earth assays in their Ancaster, Ontario assay facility. The samples were prepared and subjected to lithium metaborate fusion, followed by ICP analysis and a mass spectroscopy finish. ActLabs is an internationally respected analytical laboratory with extensive experience in rare earth element analysis.
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, neodymium, and samarium), but also small quantities of the "heavy" REE, including europium, gadolinium, terbium, dysprosium, and yttrium, as shown in Table 2.
