Stewardson 2015 Drill Program

CALGARY, March 2, 2015 /CNW/ - An exploration program and budget for 2015 was approved by Cameco Corp. (Cameco) on Uravan Minerals Inc. ("Uravan") Stewardson project. 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. Uravan is the operator and Cameco is funding the program.

2014 STEWARDSON EXPLORATION PROGRAM REVIEW

In 2014, Uravan completed two (2) diamond drill holes, SL14-001 and SL14-002, totaling 2785 meters drilled. The program was reconnaissance in nature, designed to test the uranium-bearing potential of the E-Conductor (Area A) located in the south-central portion of the property. Both drill holes targeted the footwall of the E-conductor in areas highly supported by surface geochemical anomalies [map link] [press release link].  

The E-Conductor is interpreted to be a significant basement conductive feature identified in a 2013 airborne ZTEM geophysical survey, and defined further by two (2) surface geophysical surveys in 2014: (1) a SQUID Fixed Loop TDEM survey and (2) IFG (AMT) survey. In addition to the follow up surface geophysical surveys, two (2) infill surface geochemical programs were completed over Area A (E-Conductor) and Area B (C-Conductor) [map link].  The objective of the infill surface geochemical programs was to better resolve the surface geochemical anomalies and anomalous trends identified in the 2011 surface geochemical program.

2014 DRILL PROGRAM RESULTS – OBSERVATIONS

Drilling operations for 2014 were conducted by Major Drilling Group International Inc. from Winnipeg, MN. All drill cores were systematically scanned using an ASD TerraSpec SWIR (short wave infrared) instrument for determining clay mineralogy, which provides a means of establishing the extent of hydrothermal alteration in the Athabasca Sandstone section. The drill core was routinely sampled and was prepared and assayed at Acme Laboratories in Vancouver, BC using both lithium borate fusion (method LF200; whole rock) and aqua regia digestion (method AQ250) for which 63 elements and Pb isotope ratios are determined by ICP-MS. The Queen's Facility for Isotope Research² (QFIR) conducted additional weak acid leach (WAL) analysis of core samples using High-Resolution ICP-MS for 63 elements and Pb isotope ratios. The surface SQUID Fixed Loop TDEM geophysical survey completed by Patterson Geophysics Inc. of La Ronge, SK and the IFG (AMT) survey was conducted by EMpulse Geophysics Ltd. of Dalmeny, SK.  The BHTEM surveys (Geonics BH-43-3D TEM borehole probe) were conducted by Discovery Int'l Geophysics Inc. from Saskatoon, SK. Cameco provided the technical support and equipment for completing the down-hole Resistivity surveys. The infill surface geochemical programs and management of the drill program were completed by Uravan's technical group.

2015 STEWARDSON DRILL PROGRAM

The 2015 budget allocated for the Stewardson project is estimated to fund the completion of two (2) 1500 meter diamond drill holes (DDH) on the Stewardson Project.  Based on the current evaluation of SL14-001 and SL14-002, as summarized above,  Uravan recommended to defer drilling on the E-conductor (Area A) at this time and focus on the C-conductor (Area B). This drill program will consist of drilling two (2) diamond drill holes to test the C-conductor on ZTEM lines L1330, L1350 or L1370 illustrated in the attached figure [map link].  Drill holes will be positioned to test the highest conductivity supported by 2014 infill surface geochemical anomalies. It is anticipated the drill program will commence in June 2015.

The surficial geochemical media collected over the C-conductor (Area B) reveal a number of compelling multi-element and multi-media anomalies. Radiogenic lead (²⁰⁷Pb/²⁰⁶Pb ratios) and uranium (U) anomalies in the soil clay-size fraction are supported by elevated MET³ values and high concentrations of K, Ca, Mg, Rb, Be.  The strong correlation of anomalous K, Mg and Rb in the soil clay-size fraction with a historic surface boron (B) anomaly is significant as these elements accompany hydrothermal alteration associated with unconformity-type uranium mineralization in the form of illite (K, Rb), chlorite (Mg) and dravite (Mg) clay alteration. A correlation of Na with B in the tree cores is also compelling as these are chemical constituents of dravite clay alteration [map link].  All of these anomalous surface alteration features cluster over the eastern margin of the C-conductor, which is highly suggestive of a hydrothermal 'alteration chimney' breach to the surface from a potential uranium deposit at depth.

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.

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.  

Uravan is a Calgary, Alberta-based diversified mineral exploration company that utilizes applied research to develop new 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 in the exploration stage of development.
