Uravan Completes Stewardson Drill Program - Moving Closer to Potential Discovery

TSXV: UVN

CALGARY, Aug. 19, 2015 /CNW/ - Uravan Minerals Inc. (Uravan) recently completed the second diamond drill-hole (SL15-004) of a two (2) drill-hole program on its Stewardson project. The first hole, SL15-003, intersected anomalous uranium mineralization grading 0.025% eU3O8 1 over 6.3 m, occurring at the basal unconformity2 of the Athabasca Group (MFa) sandstone, suggesting the presence of a major hydrothermal system nearby [Press Release July 20, 2015]. Based on this positive result, SL15-004 (270O AZM at -80o) was positioned west of SL15-003 to test the interpreted edge of the conductive metasedimentary basement unit (Virgin River Schist) and east of the interpreted trace of the Dufferin Lake fault [maplink]

Following the completion of a borehole time-domain electromagnetic (BHTEM) survey on SL15-003, which indicated no significant off-hole or in-hole conductive response, the vectoring strategy for positioning SL15-004 was based on the geological and geophysical similarities to the "off-conductor" uranium mineralization that occurs at the Centennial3 uranium deposit [maplink].

The positioning of SL15-004, to test the western edge of the conductive metasedimentary unit, was a valuable and necessary step in narrowing the exploration window [maplink]. Our preliminary evaluation of SL15-004 is considered positive with the intersection of numerous broad alteration sections throughout the Athabasca Group (MF) sandstone, displaying pronounced bleaching, silicification, smoky-quartz alteration (suggesting radiation damage) and illite/chlorite/kaolinite clay alteration. Although there was no significant uranium mineralization at the unconformity, these hydrothermal alteration features, along with coincident well-developed faulting and fracturing are required indicators for finding potentially higher levels of uranium mineralization nearby.

Larry Lahusen, CEO for Uravan, states "The preliminary results of drill-holes SL15-003 and SL15-004 are technically very positive, confirming that the right hydrothermal and structural components are present in Area B to host a major unconformity-type uranium deposit.  All of the key requirements in Uravan's exploration strategy for vectoring to uranium deposits under cover are intact.  More drilling is certainly required in Area B as we move closer to discovery.  Our strategy for more drilling will be announced in the coming months".

1 The uranium intersection discussed in the text above occurs from 1154.87m to 1161.17m (continuous 6.3 m with gamma counts >100 cps and consisting of 1200 and 1400 peak CPS) in drill-hole SL15-003 and was measured using a borehole Mount Sopris Triple Gamma Probe (2GHF-1000) for detecting radioactivity and calculating eU3O8  (a radiometric uranium oxide equivalent value). The total raw gamma counts from the Triple Gamma Probe were calculated using the Probe's instrument specific K-Factor after being  corrected for dead time, casing factor and water factor using WellCad software developed by Advanced Logic Technology (ALT).


2The Athabasca Basin is an ancient (Paleoproterozoic) sandstone basin located in northern Saskatchewan, Canada.  The Athabasca Sandstone (Manitou Falls (MF) Formation) hosts high-grade uranium deposits at and below the unconformity between the sandstone and the older crystalline basement rocks. These unconformity-type uranium deposits occur in sandstones at the sandstone-basement unconformity contact (sandstone-hosted mineralization) and within the underlying structurally disrupted crystalline basement (basement-hosted mineralization). These unconformity-type uranium deposits account for about 25 percent of the world's primary uranium production. The ore grades are high, typically grading 2% to 20% U308.


3 The Centennial deposit is a high-grade sandstone-hosted unconformity-type uranium deposit occurring at a depth of approximately 800 m that is currently in the drill-development stage by Cameco Corporation and its joint venture partners, Areva Resources Canada Inc. (AREVA) and Formation Metals Inc. (Coronation Mines).


Uravan is a Calgary, Alberta-based mineral exploration company that utilizes applied research to develop innovative exploration technologies to identify buried uranium deposits in under-explored areas. Our exploration focus in uranium is for potential high-grade unconformity-type uranium deposits in the Athabasca and Thelon Basins in Canada and other basin environments globally.  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 to be in the exploration stage of development.
