Surface Geochemical Study over the Centennial Uranium Deposit

CALGARY, June 18, 2013 /CNW/ - Uravan Minerals Inc. (Uravan), in collaboration 
with Cameco Corporation (Cameco), the Queen's Facility for Isotope Research 
(QFIR)(1), and Environmental BioTechnologies Inc. (EBT)(2) are conducting a 
multi-faceted surface geochemical sampling program over the Centennial uranium 
deposit (Centennial Survey), located on the Virgin River structural trend 
within the south-central portion of the Athabasca Basin(3), Saskatchewan [map 
link]. The Centennial deposit is a high-grade unconformity-type uranium 
deposit occurring at a depth of approximately 800 meters that is currently in 
the drill-developed stage by Cameco and its joint venture partners, Areva 
Resources Canada Inc. (AREVA) and Formation Metals Inc. (Coronation Mines). 
The Centennial Survey is an applied research study that will capitalize on our 
cumulative knowledge obtained from previous surface studies, including the 
Cigar West Study(4) and surveys conducted over Uravan's active exploration 
projects. The objective of this survey is to advance our remote sensing 
geochemical technology by obtaining a better understand of (a) the processes 
by which elements migrate from a deposit at depth to the surface environment, 
and (b) how these elements can be better characterized to determine whether 
they are deposit-sourced geochemical signals versus the natural geochemical 
composition of the surface environment. 
The survey will be completed in June 2013 and managed by Uravan's technical 
group. The sampling grid consists of 491 survey stations. A primary sampling 
grid covering a 600 x 950 meter area centered over the surface projection of 
the Centennial deposit will consist of 230 sample stations distributed on an 
offset 50 meter grid. An additional 261 survey stations will be distributed on 
100, 200 and 500 meter spacing extending farther into background away from the 
deposit [map link]. 
The sample media collected will consist of B- and C-horizon soils and 
tree-cores from black spruce and/or jack pine trees. Sample preparation of the 
tree-cores and separation of the clay-size fraction (<2μm) from the B-and 
C-horizon soils will be completed by QFIR. All clay-size sample material 
from the B-and C-horizons soil samples will be analysed at Acme Laboratories 
in Vancouver by ICP-MS following an aqua regia digestion for a suite of 
fifty-three (53) elements, plus all rare earth elements (REE) and lead (Pb) 
isotopes. QFIR will also conduct analytical work on tree-cores where they 
will undergo total digestion and analysis using high resolution ICP-SFMS for 
fifty (50) elements and Pb isotopes. 
A separate A-horizon soil sample from each survey station will be collected 
for analysis using EBT's Microbial Exploration Technology (MET) process. 
Conceptually, the MET analysis measures the level of hydrocarbon metabolizing 
microbes living in the near surface aerobic environment. Elevated populations 
of these micro-organisms in a soil sample may be indicative of thriving 
microbial activity due to an increase in hydrocarbon gas flux (primarily 
methane) that has migrated to the surface from the redox environment of a 
uranium ore deposit at depth. 
Since 2008, Uravan and QFIR have collaborated on several surface geochemical 
surveys and studies designed to develop new geochemical and analytical 
technologies that will help identify the surface expression of deeply buried 
unconformity-type uranium deposits with the objective to vector drilling 
toward bedrock sources of uranium mineralization. These studies have 
identified specific element associations and isotopic compositions in 
trees-cores and clay minerals from soils, which potentially originated from 
uranium mineralization at depth. 
In 2009, Uravan and QFIR completed a collaborative research study with AREVA, 
involving a multi-faceted surface geochemical sampling survey over the Cigar 
West uranium deposit, a known high-grade unconformity-type uranium deposit 
(Cigar West Survey(4)). Data analysis and interpretation of the results of the 
Cigar West Survey clearly identified anomalous pathfinder elements, lead (Pb) 
isotopic compositions ((207)Pb/(206)Pb) and elevated microbial activity (MET 
analysis) residing in the surface environment (soils and vegetation) that were 
mobilized from the deposit below at depths greater than 450 meters. 
Based on the knowledge gained from the Cigar West Study, in 2011 Uravan and 
QFIR entered into a Collaborative Research and Development grant (CRD grant) 
funded by Uravan with matching funds from the Natural Sciences and Engineering 
Research Council of Canada (NSERC)( 5) (press release dated April 26, 2011) 
These applied research studies included surface geochemical surveys over 
Uravan's Johannson, Outer Ring, Matheson, Halliday and Stewardson projects in 
the Athabasca Basin. Results from these studies revealed positive lead 
isotopic ((207)Pb/(206)Pb) compositions and associated pathfinder elements 
occurring in certain soil components (clay-separates from B- and C-horizon 
soils) and tree-core samples that potentially highlight bedrock sources of 
uranium mineralization at depth. 
As a result of these surface geochemical surveys, drill programs were 
completed in 2011 and 2012 on the Outer Ring, Matheson and Halliday projects. 
Drill-holes from these programs were positioned to test anomalous surface 
geochemical signatures that potentially correspond to uranium mineralization 
at depth. Data analysis and interpretation of the results of these drill 
programs clearly suggests that certain pathfinder elements and isotopic 
compositions that were active at the unconformity and underlying basement 
rocks have migrated to the surface environment where their concentrations have 
been measured. Although this drilling resulted in the intersection of 
anomalous radioactivity at the unconformity and underlying basement rocks, no 
economic uranium mineralization was encountered. 
Mr. Larry Lahusen, CEO of Uravan states: "The results from our 2011 and 2012 
drill programs suggest that a better correlation between the anomalous surface 
signatures and drilling results is essential. The sampling methodology and 
analytical protocols that will be carried out during the Centennial Survey are 
designed to potentially identify the geochemical signals in the soils and 
trees-cores that are related to the Centennial uranium deposit below versus 
the geochemical signature inherent from the surface media."
