CALGARY, Jan. 9, 2012 /CNW/ - In the summer 2011, Uravan Minerals Inc (Uravan) completed multifaceted surface geochemical sampling programs on the Halliday Lake, Math, OR Extension, and Stewardson Lake projects [Press Release Link] in the Athabasca Basin1, Northern Saskatchewan [map link]. These surface programs capitalized on new surface geochemical technologies developed from a pilot study conducted at the Cigar West Uranium deposit (Cigar Lake Study)2 for the detection of buried unconformity-related uranium deposits in under-explored areas in the Athabasca Basin.
The surface sampling programs resulted in the collection of a total of 3305 samples from all media over approximately 40,140 hectares. The sample media collected are B- and C-horizon soils, vegetation (from spruce and/or pine) and tree-cores (from spruce and/or pine). All sample material collected (clay separates from the B-and C-horizons soils and vegetation samples) were analysed using multi-element ICP-MS for 52 elements plus all the REE and Pb isotopes at Acme Labs in Vancouver. Sample preparation on the tree-cores and separation of the clay fraction from the B-and C-horizon soils were completed by the Queen's Facility for Isotope Research4 (QFIR) at Queen's University. QFIR will also conduct further analytical work on tree-cores and clay separates by a multi-element analysis for 52 elements plus all the REE and Pb isotopes by High-Resolution ICP-MS. The analytical data resulting from these geochemical surveys will be the focus of a collaborative research study between Uravan and QFIR, and the Natural Sciences and Engineering Research Council of Canada (NSERC) 3 [Press Release Link].
Data analysis and interpretation of the surface geochemical data from the Halliday project identified an east-west oriented highly anomalous geochemical signature that is coincident with an EM (electromagnetic) geophysical conductor and magnetic low corridor [map link]. The east-west geochemical signatures consist of anomalous radiogenic Pb isotope values occurring in the clay minerals separated from the soil media and tree-cores. These radiogenic Pb anomalies also correlate strongly with other anomalous uranium pathfinder elements occurring in the same media.
Based on the extremely positive results from the Halliday surface geochemical program, a four (4) hole diamond drill program is planned and anticipated to commence in June 2012. In preparation for finalizing drill targets, additional ground geophysics and structural mapping is anticipated to be completed over the anomalous east-west geochemical trend. More details on these surveys and the subsequent drill program will be announced in future press releases. All future exploration expenditures are conditional on securing project financing.
The Halliday project is located approximately 18 kilometers northwest of the McArthur River uranium deposit in the eastern Athabasca Basin. The Halliday property is owned 100% by Uravan and was acquired from Cameco Corporation (Cameco) in December 2010 as part of a larger property exchange agreement [Press Release Link].
Exploration work previously conducted on the Halliday project by Cameco consists of six (6) widely-spaced diamond drill holes amounting to 5167 meters drilled with drill depths averaging 850 meters. This reconnaissance drilling targeted three sub-parallel EM geophysical conductors within an east-west oriented magnetic low. Based on drill core data analysis and interpretation, the conductive zones coincide with an east-west trending graphite structural zone. Drill core analysis identified high boron concentrations within basement samples, strong illite clay alteration in the sandstone and anomalous uranium mineralization occurring at the unconformity, which assayed 800 ppm to 0.12% U3O8 over narrow intervals (<1.0 meter).
The data analysis and interpretation of the surface geochemical results from samples previously collected on the OR extension, Stewardson and Johannson lake projects are pending and will be announced as this work is completed.
Dr. Colin Dunn, P. Geo., technical advisor for Uravan, is the Qualified Person for the purposes of NI 43-101 with respect to the technical information in this press release.
1The Athabasca Basin is an ancient (Paleoproterozoic) sandstone basin located in northern Saskatchewan, Canada. The Athabasca Basin hosts high-grade unconformity-type uranium deposits that account for about 28 percent of the world's primary uranium production. These unconformity-type uranium deposits occur in sandstones at the basement-sandstone unconformity contact (sandstone-hosted mineralization) and within the underlying structurally disrupted crystalline basement (basement-hosted mineralization). The ore grades are high, typically grading 5% to 20% U308.
2The Cigar West Study was a collaborative applied research program conducted by Uravan and QFIR (Queen's Facility for Isotope Research) in 2009 over a known high-grade uranium deposit in the Athabasca Basin. The study was designed to develop new surface geochemical techniques that can better identify bedrock sources of uranium mineralization at depth. This research clearly identified distinctive elements and isotopic compositions that have been mobilized from the deposit (geosphere) to the surface media (plants and soils) from depths >450 meters. The Cigar Lake deposit is on the Waterbury/Cigar uranium property; a joint venture partnership between Cameco Corporation, AREVA, Idemitsu Kosan Co. Ltd., and Tokyo Electric Power Co. [TEPCO]) located in the Athabasca Basin, Saskatchewan. Uravan thanks both AREVA and Cameco for their collaboration and gracious support for the Cigar West Study; and the support provided by the Cigar Lake facility during our field operations.
3 The goals of this applied research study, titled 'Exploration Geochemistry for Deep Uranium Deposits', are: (1) to apply geochemical technologies recently developed by QFIR and Uravan from a pilot study (the Cigar Lake Study) 1 for remotely sensing deeply-buried deposits on Uravan's Outer Ring (OR) and other Athabasca Basin projects; and (2) to develop new geochemical technologies using isotope compositions (such as Li, C, N, Pb and U) for more reliable and definitive indicators of mineralization at depth in these highly prospective but under-explored sandstone basin areas.

The QFIR lab contains some of the most technologically advanced analytical equipment in Canada. Under the direction of Dr. Kurt Kyser, the QFIR research team is working collaboratively with Uravan's technical group to develop new exploration technologies using applied research.
Dr. Colin Dunn, an independent specialist in biogeochemistry, is working closely with Uravan's technical group and QFIR to advance the interpretation of biogeochemical results. Dr. Kurt Kyser and Dr. Colin Dunn are key technical advisors for Uravan.
Uravan is a Calgary Alberta based diversified mineral exploration company that utilizes applied research to develop new innovative exploration technologies to identify buried uranium, rare earth elements (REE) and nickel-copper-platinum group element (Ni-Cu-PGE) deposits in under-explored areas. Our exploration focus in uranium is for potential high-grade unconformity-related uranium deposits in the Athabasca and Thelon Basins in Canada and other basin environments globally. Uravan is expanding its acquisition efforts toward REE geological domains in North America and specific areas globally. The REE and uranium mineralization occur in related geological environments thereby complementing Uravan's uranium exploration efforts with a strategy to add diversification to its portfolio. Further, Uravan is pursuing the exploration of its advanced- stage Rottenstone Ni-Cu-PGE project supported by the development of new drill targets defined by recent geophysical re-interpretation. Uravan is a publicly listed company on the TSX Venture Exchange under the trading symbol UVN. All of the mineral properties Uravan owns are considered in the exploration stage of development.
