Ucore Confirms Widespread Rare Earth Mineralization In Central Alaska

is pleased to announce results of reconnaissance sampling on the Company`s extensive alluvial rare earths (REE) and tin multi-metal property holdings in the Ray Mountains area of central Alaska (). Sample results from late summer field investigations point to potential economic grade concentrations in at least three drainage basins: the upper Kilolitna River, the Ray River, and No Name Creek. Each of these exhibits numerous surface exposures of alluvial gravel and sand containing a threshold of at least 0.15 kg/cubic meter (0.22 lbs/cubic yard) of REE and/or tin (Sn), along with by-product concentrations of tungsten (W), zirconium (Zr), niobium (Nb), and tantalum (Ta). Locally samples contain up to 1 kg/m3 each of Sn and REE in the extensive floodplain of the Ray River. Mineralized sediments from No Name Creek and the Caribou Heights prospects contain up to 9 kg Sn/m3.

The sampling program has rendered heavy mineral concentrates composed primarily of ilmenite with cassiterite, monazite with lesser xenotime, zircon, wolframite (ferberite end-member), and trace amounts of allanite, scheelite, and yttrofluorite. The concentrates contain up to 50% Sn, up to 10% total REE (TREE), and 0.01 to 1.0% W, Ta, and Nb. Heavy rare earth elements (HREE`s), including Tb, Dy, Er and Y, compose 15 to 25% of the TREE in the majority of samples, with the notable exception of localized areas such as No Name Creek valley, which delivered TREE content comprised of up to 60% HREE`s.

"With the cooperation of the State of Alaska, Ucore continues to expand and advance its rare earth holdings in the most prospective areas of the state" said Jim McKenzie, President and CEO of Ucore. `"The intent is to establish Alaska as the leader in American heavy REE exploration, extraction and development. The Ray Mountains project has select areas rivaling HREE content at our Bokan property, and the remarkable advantage of collateral tin, niobium and tantalum mineralization which enhances prospective values per ton. Ucore will be advancing the Ray Mountains area as a priority exploration target as it transitions its Bokan flagship into mine development."

Most samples collected during the 2011 field program consisted of one or more 5-gallon buckets (0.0133 m3) of material that was later concentrated on a standard shaking table. This procedure achieved an estimated 75 to 80% recovery of heavy minerals including REE-bearing minerals such as monazite and xenotime, thus demonstrating amenability to physical separation in a full scale mine plant. This simple gravity separation method uses only water as the separation medium. Further, extraction technology of REE from a monazite-xenotime placer concentrate is already well known and does not present new metallurgical challenges. The smaller samples were panned by experienced personnel.

Sample details, including original volumes, the recovered weight of heavy mineral, rare metal analyses, and the calculated grams of TREE and Sn per cubic meter can be accessed at . All samples were analyzed by ALS Minerals, Inc. in Vancouver, using lithium metaborate fusion followed by ICP-MS analyses. Overlimit metal concentrations were further assayed by X-ray fluorescence procedures preceded by sample fusion.
