Ucore Updates Drill Results

HALIFAX, NOVA SCOTIA--(Marketwire - March 4, 2011) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE U.S.

Ucore Rare Metals Inc. (TSX VENTURE:UCU)(OTCQX:UURAF) ("Ucore" or "the Company") is pleased to announce remaining pre-resource drill results from the 2010 drill program at its Bokan Mountain Project in southeast Alaska.

The 2010 drill program produced a total of 3,770 metres of core from 18 diamond drill holes. Thirteen of these holes were drilled in the Dotson Zone to extend the limits of known information and to provide adequate sampling to support the calculation of a National Instrument 43-101 compliant resource, to be released within the next two weeks. Hole LM10-82 was drilled in the centre of the Dotson Zone to test the mineralization at depth and between drill sections. Holes LM10-83 to LM10-86 were drilled at the west end of the deposit on two section lines. Mineralization intersected in these holes is offset slightly to the north by a local fault and is similar in style and grade with mineralization intersected in trenches along the zone (see Ucore press releases dated November 30, 2010 and December 22, 2010).

Additionally, three holes were drilled at Sunday Lake to test for an extension of the high grade near surface mineralization at depth, and two holes were drilled on the Geoduck Zone to test the extension of that vein system. At Sunday Lake, holes were drilled from west to east across the intrusive contact beneath the Sunday Lake showing, with all drill holes intersecting mineralization at or near the contact between metasediments and the Bokan Granite. This mineralization was similar in style but lower in tenor to that intersected at shallower depths beneath Sunday Lake. At the Geoduck Zone, hole LM10-90 was drilled across the inferred extension of the zone, and Hole LM10-91 was drilled to the northeast of the zone, with the latter hole intersecting multiple mineralized zones which appear to be the northern extension of the Geoduck Zone in this area.

A map showing the location of the drill holes from the Dotson Zone reported in this press release is located at the following web link: http://www.ucoreraremetals.com/bokan.asp. The following table summarizes significant intersected values for Holes LM-10-82 to LM-10-91 inclusive:

"Ucore is just days away from releasing an NI 43-101 compliant Inferred Resource estimate for the Dotson Zone," said Jim McKenzie, President and CEO of Ucore. "Our 2010 results continue to confirm the unusually high skew in the Dotson Zone toward heavy rare earths, including some of the most valuable, essential and sought after metals in the American defense and high technology sectors. What's more, they reinforce the conclusions of recent USGS studies ranking Bokan as one of three significant rare earth deposits in the U.S., and the one with the highest relative content of critically threatened strategic heavy rare earths such as Dysprosium and Terbium. With our compliant resource in hand very shortly, Ucore intends to pursue an aggressive near term mine feasibility and development schedule."

The 2010 exploration program has now established both the continuity and integrity of mineralization in the Dotson Zone. The zone is characterized by a strike length of more than 2,000 m and an average width of 50 m, and remains open both at depth and along strike. The Dotson Zone is comprised of at least 24 high-grade mineralized veins or vein-arrays. The NI 43-101 compliant resource calculation, pending shortly, will consist solely of high-grade veins of mineable width. Significantly, the 2010 exploration results support the historical USBM model for the area (Barker & Warner, USBM OFR 33-89), which infers persistent rare earth mineralization in the zone both along the strike and at depth, in addition to an extraordinarily high ratio of heavy to total rare earth elements.

In tandem with the calculation of a NI 43-101 compliant resource estimate, Hazen Research Inc. of Golden, Colorado, is conducting mineralogical and metallurgical studies on bulk samples taken from the Bokan-Dotson Ridge project. Results from this work are anticipated to be released in the near term.

On Feb 22, 2011, the State of Alaska reinforced its intention to pursue the development of its significant rare earth resources. In a letter from Alaska Governor Sean Parnell to President Barack Obama, the Governor urged the White House to direct the U.S. Geological Survey to undertake a full inventory of prospectively critical rare earth resources located in Alaska as an alternative to America's current heavy dependence on Chinese sources. The Governor additionally called for an expediting of the federal permitting process for rare earth mines, and urged the President to work with Congress to review the merits of amending existing federal statutes to provide the U.S. Department of Energy with authority to provide loan guarantees, grants, and tax credits for the general mining and processing of REE's.

NI 43-101 Compliance

Diamond drill core was split on site, with half the core transported by commercial carriers to the Activation Laboratories analytical facility in Stewart, B.C., Canada and check assay samples submitted to ALS Laboratories in Whitehorse, Yukon Territory, Canada. Sample containers were sealed and chain of custody was maintained throughout transport. The QA/QC program included the insertion of duplicates, blanks and certified standards in the submitted sample shipments; and laboratory insertion and analysis of standards and blanks, duplicates and resplits. Analyses were made by inductively-coupled plasma mass spectrometry with lithium metaborate fusion, reporting whole rock analyses as an additional quality control measure. Reported values are length-weighted averages from multiple samples. All widths reported are core intercepts; insufficient structural information is available to make a conclusive statement on the relationship between true width and core intercept. Mike Power, P.Geo. (BC), CPG (AIPG), an independent geologist with Aurora Geosciences (Alaska) Ltd. and a qualified person in accordance with NI 43-101, has reviewed and approved the technical content of this press.

Background

Ucore Rare Metals Inc. is a well-funded junior exploration company focused on establishing REE, uranium and other rare metal resources through exploration and property acquisition. With multiple projects across North America, Ucore's primary focus is the 100% owned Bokan - Dotson Ridge REE property in Alaska.

The Bokan - Dotson Ridge project is located 60 km southwest of Ketchikan, Alaska and 140 km northwest of Prince Rupert, British Columbia and has direct ocean access to the western seaboard and the Pacific Rim. The property is located in an area reserved for sustainable resource development with an existing road network providing access to the main target areas. REE mineralization at the Bokan - Dotson Ridge project occurs in a well-demarcated vein system related to a Mesozoic peralkaline granitic complex. The Bokan - Dotson Ridge project is the only rare earth project currently documented worldwide which is situated on immediate deep water access, considered a significant advantage in expediting mine production and limiting the capital costs associated with mine construction.

In 1989, a U.S. Bureau of Mines study (Warner & Barker, USBM OFR 33-89) estimated that the greater Bokan area contains 374 million lbs of TREO (a historical non-NI 43-101 compliant estimate) and ranks as one of the most prospective and accessible heavy rare earth prospects in North America. The Warner & Barker report additionally concluded that there is a significant collateral mineralization of Nb, Ta and Zr at Bokan.

In 1996, a U.S. Bureau of Mines study (Green & Harbuck) concluded that: "The Bokan Mountain area on Prince of Wales Island, AK, contains vast quantities of heavy rare earth minerals." The report went on to postulate that the liberation of yttrium, considered a proxy for the prospective liberation of all HREE's, is highly amenable to metallurgical cracking methodologies.

A recent Ucore press release (see Ucore press release dated November 15, 2010) noted that the Dotson vein system has a high potential for an efficient mining and milling operation with rather limited environmental impact. Furthermore, the SGS Laboratories of Lakefield, Ontario (an NI 43-101 compliant report, see Ucore press release dated April 8, 2009) documented that the REE minerals can be mechanically liberated from Bokan mineralized host material.

Readers are cautioned that the resource estimates quoted by the US Bureau of Mines were prepared prior to the implementation of National Instrument 43-101 and are therefore of a historical nature. No qualified person has done sufficient work to classify the historical estimate contained hereunder as current mineral resources. The Company is not treating the historical resource estimate as a NI 43-101 defined resource or reserve, and therefore the historical resource estimate should not be relied upon.

This press release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address future exploration drilling, exploration activities and events or developments that the Company expects, are forward-looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include exploitation and exploration successes, continued availability of financing, and general economic, market or business conditions.
