Surface Geochemical Study Completed over the Centennial Uranium Deposit

Surface Geochemical Study Completed over the Centennial Uranium Deposit 
(TSXV: UVN) 
CALGARY, Dec. 16, 2013 /CNW/ - Uravan Minerals Inc. (Uravan), in collaboration 
with Cameco Corporation (Cameco), the Queen's Facility for Isotope Research 
(QFIR), and Environmental BioTechnologies Inc. (EBT), completed 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, Saskatchewan [map 
link]. The Centennial deposit is a high-grade unconformity-type uranium 
deposit occurring at a depth of approximately 800 m 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 capitalized on our 
cumulative knowledge obtained from previous surface studies, including the 
Cigar West Study and similar surface geochemical surveys conducted over five 
(5) of Uravan's active exploration projects. The purpose in developing these 
surface geochemical techniques is to provide a means of rapidly evaluating 
under-explored basin environments with the goal to get to mineral discovery 
more quickly and cost effectively (i.e. fewer drill-holes to discovery). The 
objective of this survey is to advance our remote sensing geochemical 
technology by (a) determining if we can identify unique geochemical and 
isotopic signatures in the surface environment (soils and trees) that support 
element migration from a high-grade uranium deposit at depths >800m; and (b) 
investigating if these elements and isotopic signatures can be characterized 
as distinct, deposit-sourced geochemical signals or derived from the natural 
geochemical variations related to surficial geology and/or environmental 
effects. 
The survey was completed in June 2013 and managed by Uravan's technical group. 
The sampling grid of 533 survey stations: (a) a primary sampling grid covering 
a 600 x 950 m area was centered over the surface projection of the Centennial 
uranium deposit. The central grid included 230 sample stations distributed on 
an offset 50 m grid. An additional 303 survey stations were distributed on 
100, 200 and 500 m spacing extending further into background away from the 
deposit [map link]. 
Sample Media Collected 
1. 495 B- and C-horizon soil samples;
  2. 478 tree-core samples from black spruce and/or jack pine trees;
  3. 557 MET samples from A2-horizon soils and;
  4. 45 bulk B-horizon soil samples. 
Sample Preparation and Analysis 
Sample preparation of the tree-cores and separation of the clay-sized fraction 
(<2μm) from the B-and C-horizon soils were completed by QFIR. All 
clay-sized sample material from the B-and C-horizon soil samples were 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 undertook the preparation and analytical work on 
all tree-cores. Selected tree-ring intervals underwent total digestion and 
analysis using high resolution ICP-SFMS for fifty (50) elements and Pb 
isotopes. 
A separate A2-horizon soil sample from each survey station was collected for 
analysis using EBT's Microbial Exploration Technology (MET) process. 
Conceptually, the MET analysis measures the population 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 deposit at depth. 
Survey Results - Data Analysis and Interpretation 
The combined anomalous surface geochemical signals obtained from the various 
surface media analyzed (tree-cores, clay-sized fractions of soils, and MET 
samples) have clearly defined the surface projection of the Centennial uranium 
deposit, which occurs at depths greater than 800 m [map link]. The spatial 
relationship and surface distribution of certain pathfinder elements, lead 
(Pb) isotopic ratios ((207)Pb/(206)Pb), and MET microbial values in the media 
analyzed, provide a compelling, coincident surface anomaly that, when 
displayed with other known geophysical survey data and interpreted structural 
patterns, would certainly vector drilling to a deposit at 800 meters depth in 
a 'green-fields' exploration setting. 
These anomalous surface geochemical signals are interpreted to be the result 
of the migration of gaseous compounds, mobilized metals, and distinct isotopic 
compositions from the deposit at depth. The movement of these distinct 
elements and gaseous compounds to the surface environment (soils and trees) is 
interpreted to occur preferentially along fractures and fault systems, as well 
as along grain boundaries through the Athabasca Sandstone. The structural 
pathways extending upward through the overlying Athabasca Sandstone are a 
result of basement structural reactivation and concurrent hydrothermal 
activity, both of which are key components necessary for all 
unconformity-related uranium deposits in the Athabasca Basin. 
Proof of Concept 
A drilling program on the Stewardson Lake project is the next step in Uravan's 
objective to apply our cumulative knowledge from these surface geochemical 
surveys to active projects. In July 2011 a surface geochemical program was 
completed over the Stewardson project followed by an airborne ZTEM geophysical 
survey in June 2013 [map link]. A program and budget for the Stewardson 
project for 2014 is currently under review by Cameco Corporation (Cameco). 
Cameco has an exclusive option to earn a 51% interest in Uravan's 100% owned 
Halliday Lake and Stewardson Lake projects. Uravan is currently the operator 
with the responsibility to plan and implement the exploration programs on the 
Stewardson project in consultation with and on behalf of Cameco. Details of 
the approved 2014 program and budget will be announced in the near future.
