CALGARY, Aug. 22, 2011 /CNW/ -- TSXV: UVN CALGARY, Aug. 22, 2011 /CNW/ - Uravan Minerals Inc. (Uravan) recently completed a five (5) hole  diamond drilling program totaling 4237 meters drilled on its Outer Ring (OR) project in the Pasfield Lake area of the Athabasca Basin(1) [view map]. The OR drill program was reconnaissance in nature that targeted select surface signatures identified from a multifaceted surface geochemical sampling program completed over the OR property in 2010. This surface geochemical program capitalized on new innovative geochemical technologies developed by Uravan's technical group and collaborative research partners from a pilot study conducted on the Cigar West uranium deposit (Cigar West Study)( 2). First indications of potential uranium-bearing intersections from drill-holes OR11-01 to OR11-05 were obtained from down-hole Natural Gamma surveys (description below). All drill holes intersected zones of high radioactivity (levels 7.5 times background) occurring over significant intervals in the Athabasca Sandstone(1) at the unconformity(3 )and over broad zones below the unconformity in the underlying basement rocks. All zones of high radioactivity intersected were systematically sampled and will be assayed for their uranium concentrations; analytical results will be announced when available. The following table summarizes the significant intersections as determined from down-hole Natural Gamma surveys: _______________________________________________________________ |Drill Hole|From (m)|To (m)|Interval (m)|API (cps)*| Occurrence | |__________|________|______|____________|__________|____________| | OR11-01 | 662.45 |672.35| 9.90 | 432 |unconformity| |__________|________|______|____________|__________|____________| | OR11-02 | 724.58 |737.98| 13.40 | 349 |unconformity| |__________|________|______|____________|__________|____________| | | 763.18 |772.93| 9.75 | 475 | basement | |__________|________|______|____________|__________|____________| | OR11-03 | 780.12 |781.07| 1.00 | 640 |unconformity| |__________|________|______|____________|__________|____________| | OR11-04 | 764.41 |770.51| 6.10 | 707 |unconformity| |__________|________|______|____________|__________|____________| | OR11-05 | 742.26 |754.16| 12.00 | 288 |unconformity| |__________|________|______|____________|__________|____________| | | 756.46 |795.36| 39.00 | 402 | basement | |__________|________|______|____________|__________|____________| *Note: An API (American Petroleum Institute) unit is a standard measurement of gamma radiation encountered in borehole surveying by Natural Gamma probes. The radioactivity levels indicated in the table above are considered significant, albeit not quantitative, and represent the presence of uranium concentrations that are several levels above normal background radioactivity. Coincident with these zones of high radioactivity, some drill-holes intersected other geological features suggestive of a geochemically and structurally active unconformity surface; key features required for uranium mineralization: -- Persistent sandstone bleaching above the unconformity coincident with broad zones of secondary hematite alteration; -- the presence of illite( )clay alteration occurring over varying thicknesses at and above the unconformity, and; -- The presence of major fracturing radiating up into the Athabasca Sandstone and faulting in the underlying basement units; all suggestive of structural reactivation. The combined assessment of all data collected at this preliminary stage has allowed Uravan's technical team to significantly advance and refine favourable target areas for future diamond drill programs. Mr. Larry Lahusen, CEO of Uravan states: "Although a lot of data analysis is still in progress, the intersection of high radioactivity, coincident structure, and clay alteration arising from the OR drill program is highly encouraging and tells me we are in the right neighbourhood.  Most importantly, this reconnaissance drill program validates the surface geochemical signatures tested and strongly supports our surface geochemical approach". All drill holes (OR11-01 to OR11-05) were probed using a suite of high-resolution (10cm or 5cm increments) down-hole geophysical survey tools consisting of: Natural Gamma, Neutron, Gamma-Gamma Density and Electric Resistivity/Spontaneous Potential. The logging equipment and operational expertise was provided by DGI Geoscience Inc. based out of Toronto. This suite of borehole survey tools has provided accurate and continuous down-hole logs of physical rock properties allowing Uravan's technical group to link the geophysical data to other critical whole-rock analytical data, spectral clay mineralogy and lithological data collected from core. All drill cores were systematically scanned using ASD Terraspec instrumentation for determining clay mineralogy; a means of establishing the presence or lack of hydrothermal alteration. The drill core has been routinely sampled and will be assayed by multi-element ICP-MS for 52 elements plus all the REE and Pb isotopes at Acme Labs in Vancouver. The Queen's Facility for Isotope Research(4) (QFIR) will conduct further analytical techniques on core samples to determine the concentration of certain isotopic compositions using High-Resolution ICP-MS. The analytical data resulting from the core recovered from the OR drilling program will be the focus of a new collaborative research study between Uravan and QFIR, and the Natural Sciences and Engineering Research Council of Canada (NSERC)( 4) [PR dated April 26, 2011]. The OR drill program was managed and directed by Uravan's technical group. Drilling operations were performed by Bryson Drilling Ltd. from Archerwill, Saskatchewan. 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. (1)The 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 (Athabasca Sandstone) 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% U(3)0(8).The interior of the Athabasca Basin, which includes the OR property, is under-explored relative to the high-grade unconformity-related uranium deposits currently being exploited near the eastern margin of the basin. The OR drill program is one of the first significant exploration effort conducted in this more basin-ward region and even more significant considering the drilling is targeting surface geochemical anomalies versus conventional blind geophysical (EM) conductors. (2)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. The 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. (3)Unconformity in this writing is defined as the contact between the Athabasca Sandstone and the underlying crystalline basement rocks.
