"The completion and analysis of the 2011 drill program is another significant milestone for Ucore," said Jim McKenzie, President and CEO of the Company. "The 2011 drill program is remarkable for being the most ambitious to date, generating more linear metres of core during one season than in all of the previous drill seasons combined. The sheer size of the 2011 program clearly demonstrates that Ucore is rapidly increasing the scale and intensity of its development activities at Bokan. What's more, the rare earth grades obtained this year surpass all prior years, with several intercepts ranging from 2-3% TREO. The total core volume generated this year has been more than sufficient to upgrade the bulk of the existing resource from Inferred to Indicated under NI 43-101 guidelines, as the Company counts down to the release of a Preliminary Economic Assessment in the near future."
The 2011 exploration program confirmed the integrity and continuity of the Dotson Zone. The zone has a strike length of more than 2,000 metres, with an average width of 50 metres, and contains at least 24 high-grade mineralized veins or vein-arrays. The zone remains open both at depth and on strike. 2011 drill results show that there are multiple wide and high grade intersections within the steeper holes, indicating that the already high grade mineralization is apparently strengthening at depth. The results both reinforce and augment the historical U.S. Bureau of Mines resource estimate and geological model for the area (Warner & Barker; USBM OFR 33-89). The USBM model inferred persistent rare earth mineralization in the subject zone both along the strike and at the depth, in combination with anomalously high ratios of heavy to total rare earth elements.
In addition to standard Diamond drilling, the 2011 field program included the generation of numerous bulk surface samples. These bulk samples are serving as input material for plant-scale metallurgical and innovative X-ray transmission ore sorting testwork being conducted at Hazen Research Inc. of Golden Colorado and Commodas Ultrasort of Hamburg Germany, respectively (see Ucore press release "Ucore XRT Testing Shows Prospective Doubling of Mill Feed Grade" Oct 31, 2011). The 2011 field program additionally included comprehensive environmental baseline testing, as well as desktop engineering studies, as a prelude to mine planning and development commencing in 2012. Beyond the central exploration targets at Dotson Ridge, Ucore exploration geologists conducted surface work at several Bokan-area REE occurrences in 2011, using prior USBM studies as a means of generating outbound targets.
NI 43-101 Compliance
The 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 analyzed at their labs in Ancaster, Ontario. Check assay samples were submitted to ALS Laboratories in Anchorage, Alaska, USA and analyzed at ALS Laboratories in Vancouver, B.C. Sample containers were sealed and chain of custody was maintained throughout the transport. The QA/QC program included the insertion of certified standards, blanks and duplicates in the submitted sample shipment; and laboratory insertion and analysis of standards and blanks, duplicates and re-splits. 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 and do not reflect true width of the mineralized structure. Jim Robinson, P.Geo. (NWT), an independent geologist with Aurora Geosciences, has prepared the technical data relative to the drill assays provided herein and is the qualified person responsible for their accuracy.
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 REE 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, a significant advantage in expediting mine production and limiting the capital costs associated with mine construction.
The Bokan properties are 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 Bokan peralkaline granitic complex. However, a number of other occurrences of REE mineralization are also located within, or at the margins of the complex. Viewed in a geological and geophysical context, the Bokan complex is a distinctive circular structure and is highly prospective for rare earth deposits.
