Update - Stewardson Project

CALGARY, Dec. 10, 2015 /CNW/ - Uravan Minerals Inc. ("Uravan ") has presented a 2016 exploration program and budget for its Stewardson Project to Cameco Corporation (Cameco). The 2016 exploration drill-hole targeting strategy has been discussed and initial drill targets have been identified in Area B [map link]. The Stewardson Project budget is being reviewed by Cameco. Uravan anticipates a definitive answer will be provided in early January 2016.

The Stewardson Project is located on the Virgin River structural trend within the south-central portion of the Athabasca Basin1, Saskatchewan [map link].  The Stewardson Project is a joint exploration effort between Uravan and Cameco pursuant to the Halliday/Stewardson Option Agreement [press release link]. Uravan owns 100% of the Stewardson property and Cameco is earning an interest. Cameco has until April 2018 to complete the First Option. Uravan is the operator and Cameco is funding the program.

HIGHLIGHTS – 2015 Stewardson Exploration Program

  1. Two diamond drill-holes (DDHs), SL15-003 and SL15-004, were completed in Area B (C-conductor) along section L1330N (ZTEM flight line) totaling 2576 meters drilled [map link].
  2. SL15-003 tested the interpreted 2D and 3D inversion-modeled conductor traces based on the 2013 airborne ZTEM2 geophysical survey focusing on where these conductive features were strongly supported by surface geochemical anomalies, such as radiogenic lead (207Pb/206Pb ratios), uranium (U) and other pathfinder elements in the soil clay-size fraction, and elevated MET3 values.
  3. SL15-003 intersected anomalous uranium mineralization grading 0.025% eU3O8 over 6.3 m4 in the basal Athabasca Group sandstone (MFa) at the unconformity. The thickness and level of radioactivity intersected is considered indicative of potentially higher-grade uranium mineralization nearby.
  4. Following the completion of SL15-003, a borehole time-domain electromagnetic (BHTEM) survey determined that no significant in-hole nor off-hole conductive response could be detected nearby. The off-conductor characteristics of the uranium intersection in SL15-003 could be analogous to the Centennial uranium deposit; commonly referred as 'off-conductor' uranium mineralization.
  5. SL15-004, positioned east of the interpreted Dufferin fault, targeted the western edge of the 2D inversion defined conductive unit [map link]. This vectoring strategy was based on Cameco's experience knowing the analogous position to the Centennial5 deposit.
  6. SL15-004 intersected above background radioactivity (173 CPS over 3.65 m with several values >300 CPS) occurring 33 m above the unconformity, hosted by a conglomerate sequence of the basal Athabasca Group sandstone (MFa).
  7. Both drill-holes intersected alteration 'chimneys' extending >300 m into the sandstone section above the unconformity [map link]. This significant hydrothermal alteration feature is defined by:
    • Visual observations of drill core, such as sandstone bleaching and secondary hematite alteration over broad intervals;
    • Systematic drill core lithogeochemical analysis identifying substantial radiogenic 207Pb/206Pb ratios of <0.41 through the sandstone section, and consistent U >1 ppm throughout the lower sandstone (>240m) coincident with several pathfinder elements;
    • Systematically scanned drill core with SWIR instrumentation to determine clay mineralogy, highlighting moderate to intense chlorite + kaolinite + dravite clay alteration, coincident with secondary hematite alteration;
    • Well-developed fracturing extending from the basement into the overlying sandstone section, indicative of post-Athabasca basement fault reactivation and;
    • The presence of smoky-quartz in sandstone fractures and veins suggestive of radiation-induced defects from uranium-bearing fluids.

Larry Lahusen, CEO for Uravan, states, "The technical highlights discussed above are understandably complex. However, to add perspective, all of the significant alteration features described in SL15-003 and SL15-004 are consistent with the same level of alteration intensity found in drill-holes proximal to major unconformity-type uranium deposit in the Athabasca Basin. 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 potential discovery. Our strategy and time-lines for more drilling in 2016 will be announced in January 2016".

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. Dr. Colin Dunn, an independent specialist in biogeochemistry, is working closely with Uravan's technical group and QFIR6 to advance the evaluation and interpretation of surface geochemical data.

1The 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. 

 2Geotech's natural sources Z-Axis Tipper Electromagnetic (ZTEM) system is considered ideal for imaging basement conductors where the unconformity depths are greater than 800 m in the Athabasca Basin. The key features of the ZTEM system, which provided high quality EM data collected over the Stewardson Project, are: (1) its high spatial resolution (8 to 10 m), (2) excellent resistivity discrimination for detection of conductive basement anomalies, and (3) low frequency penetration through the overlying conductive Athabasca Sandstone, resulting in depth resolution greater than 1500 m.

3The MET (Microbial Exploration Technology) assumes that gaseous hydrocarbons (methane) migrate to the surface environment from the redox environment at the surface of a uranium deposit at depth. These hydrocarbons serve as a nutrient source that promotes the growth of soil-based micro-organisms that exist in the aerobic zone of the surface environment. The MET process then measures the increased microbial activity from each soil sample collected.

4The uranium intersection 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).

5The 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).

6The Queen's Facility for Isotope Research (QFIR) at Queens's University, Ontario, is a state-of-the-art research facility comprising a group of highly experienced research geochemists. 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.
