UCORE FIELD PROGRAM CONTINUES TO DELINEATE HEAVY RARE EARTH MINERALIZATION AT BOKAN

Ucore Rare Metals Inc. has released initial assay results from Ucore's 2010 field program at the Bokan-Dotson Ridge rare earth project in southeast Alaska. The field program, comprising extensive surface trenching and channel sampling, was undertaken to supplement subsurface drilling and to obtain a greater understanding of overall deposit dimensions at the Dotson zone.

The 2010 field program confirms that the Dotson zone, with an average total width of approximately 50 metres, contains a minimum of 25 mineralized dikes and veins. The zone dips steeply to the north, with a delineated strike length of 2,140 m and a defined vertical extent of 450 m. The zone is open both at depth and on strike.

Notes

TREO: total rare earth oxides: LREO and HREO
LREO: light rare earth elements: La, Ce, Pr, Nd and Sm
as oxide
HREO: heavy rare earth elements: Eu, Gd, Tb, Dy, Ho, Er, 
Tm, Yb, Lu and Y as oxide
% HREO: HREO as per cent of TREO (HREO/TREO)
Samples were collected using manual methods and are  
limited in extent by the depth of overburden in some
cases.
All widths are apparent widths and may be less 
than true width of mineralization at surface.

"The purpose of this field program has been to establish the summary characteristics of the mineralized system at the Dotson zone, including localization, dimension, shape and overall consistency of the REE concentrations across the area," said Jim McKenzie, president and chief executive officer of Ucore. "The results confirm the highly anomalous heavy rare earth enrichment at Bokan, among the highest heavy rare earth skews on record in North America and worldwide. They also confirm the consistent nature of the mineralization throughout, again surpassing the historical geological model for the Bokan area as set out by the U.S. Bureau of Mines. This data will additionally augment the generation of an NI 43-101-compliant resource estimate for the zone, due in the near term."

A recent report by the U.S. Geological Survey, issued November, 2010, summarizes the major rare earth deposits within the United States (USGS, Bureau of the U.S. Department of the Interior; The Principal Rare Earth Elements Deposits of the United States, Report 2010-5220). The report concludes that the heavy rare earth enriched mineralization at Bokan could have considerable economic potential.

The observations of Ucore's 2010 field program support the conclusions of the USGS, indicating that the vein arrays of mineralization of the Dotson zone are of anomalously high HREE content and of minable widths. As reported in the Ucore news release in Stockwatch of Nov. 16, 2010, the vein system has a high potential to be mined both efficiently by well-proven methods and with minimal environmental impact.

The 2010 field program assays are consistent with the findings of Dr. Anthony Mariano of Carlisle, Mass., and SGS Laboratories of Lakefield in Ontario (an NI 43-101-compliant report; see Ucore news release in Stockwatch dated April 8, 2009). The SGS studies demonstrated that the REE minerals can be effectively liberated via physical separation methodologies. The SGS and Mariano studies additionally concluded that the bulk of REE mineralization is present in minerals such as bastnaesite and iimorite, which are relatively easy to crack or break apart into their elemental constituents. A summary mineralogical and metallurgical report, augmenting the SGS and Mariano studies, as well as prior metallurgical work performed by the USBM laboratories in Salt Lake City, Utah (Green and Harbuck, 1996; see Ucore news release in Stockwatch dated Sept. 3, 2009), is pending from Hazen Research of Golden in Colorado in the near term.

NI 43-101 compliance

The channel samples were cut with a diamond blade saw at approximately 90 degrees to the strike of the same steeply dipping vein structure of the Dotson zone. Reported values are length-weighted averages from multiple samples. True width is estimated to be between 80 and 90 per cent of the reported sample width. Sample containers were sealed and the chain of custody was maintained throughout transport.
