Uranium Corp. (TSX-V: ESO), (the “Company” or “ESO”) and its 50% Joint Venture (JV) partner Fission Energy (TSX-V: FIS), are pleased to announce the start of a $2.76M, 33 hole winter drill program at their PLS Property.  The winter drill program, a follow-up to the November drill program (see news release dated November 9, 2011 and update below) will include Sonic and/or RC Drilling, Core Drilling, and Airborne and Ground Geophysics. 

“We feel that the encouraging results to date at the PLS property have warranted an aggressive exploration program for this winter.  We believe that this program presents an excellent opportunity to locate the bedrock source of the high grade uranium boulders discovered in June 2011.” Commented Garrett Ainsworth, Project Manager.  Further information on the winter program will be provided. 

The following is an update to the drill program at the PLS Property, which began in November, 2011. This program tested 75 – 108 meters (m) of overburden through to the basement rocks on the “up-ice” side of the high grade uranium boulder field discovered in June 2011, in an effort to locate radioactive till sheets in the overburden and to determine the extent of Cretaceous on-lap over the basement rocks.

Seven vertical diamond drill holes (PDD11-01 to 07) totaling 838m using HWT and NW casing through the overburden were completed and surveyed with a Mount Sopris downhole 2PGA-1000 gamma probe (see Table 1).  Background radioactivity in the overburden ranged from 0 to 20 cps.  Drill holes PDD11-06 and 07 showed anomalous radioactivity in overburden intersections from 64.4m to 70.0m (maximum peak of 400 cps) and from 49.6m to 58.2m (maximum peak of 90 cps), respectively.  PDD11-07 was located between PDD11-06 and the area of radioactive boulders trenched in October, 2011. The shallower depth of the anomalous radioactivity in PDD11-07 could be consistent with a semi-continuous till sheet dipping to the northeast towards a possible up-ice bedrock source for the uranium boulders.  Further drilling will be required to determine if these initial results represent an intersection of the radioactive till sheet being sought.  PDD11-03 intersected graphitic metapelitic basement rocks.  Noteworthy, the unconformity was intersected between 10-20m deeper than nearby adjacent PDD11-02 and 04 and may reflect a basement fault off-set.  Basement faulting and graphitic metapelites are often seen as key ingredients associated with structurally controlled uranium mineralization in this region.   

TABLE 1:

Core samples from basement rocks and clay alteration samples were collected and have been sent to SRC for multi-element analysis and Northwind Resources Ltd. for PIMA spectral analyses to determine select clays and associated minerals for comparison with typical alteration assemblages associated with uranium mineralization in this geological setting.

Each drill hole is surveyed downhole for radioactivity with a Mount Sopris 2PGA-1000 Gamma/SP probe. Samples have been submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis, which include a 63 element ICP-OES, uranium by fluorimetry (partial digestion). Assays will be reported when available.

PLS is a 50%/50% Joint Venture held with FISSION Energy (FIS). Patterson Lake South is accessible by road with primary access from all weather Highway 955, which runs north to the former Cluff Lake mine, (>60M lbs of U3O8 produced), and passes through the nearby UEX-Areva Shea Creek discoveries located 50km to the north, currently under active exploration and development.
