HUNT FOR HIGH GRADE URANIUM SOURCE STARTS ON PATTERSON LAKE SOUTH JV, SASKATCHEWAN
ESO 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 that all permits for a programme of drilling, trenching and ground geophysical surveys has been received. Work has started in the search for the bedrock source of a large uranium boulder field discovered by the Joint Venture in June 2011 (see news release dated July 27, 2011). This work includes:
�         Definition of local ice transport directions (underway)
�         MaxMin EM surveys to re-locate historical conductors on the ground
�         Resistivity survey to identify potential basement alteration zones
�         Drilling to locate radioactive debris in glacial till from basement sources
�         Drilling of high grade basement targets
The uranium boulders discovered in June were all associated with basement rocks, schists, psammites and granulites, and not Athabasca sandstones or conglomerates. These boulders were plucked from a basement source by ice scouring Archean basement rocks.
The target area is within a defined window of Archean rocks that are buried by 50-60 meters of till cover. The window was opened by glacial scouring along the southern edge of the Athabasca basin that also removed some of the younger Cretaceous cover. The programme is targeting high grade uranium deposits hosted in basement rocks, similar to those deposits found in the lower parts of the Shea Creek deposit (60 kms (40 miles) north of Patterson Lake) and the Millenium, Key Lake and Roughrider mega-deposits in the eastern Athabasca Basin. The 5 km length of the boulder field and distinct clusters of associated geochemical values in the boulder field suggest more than one source for the boulder field.
Drill targetshave been selected, subject to modification by information from this new work program. The targets were determined by a review of technical data, including geophysical surveys and parameters suggested by diamond drill hole information in assessment reports presented by Canadian Occidental in the late �70s.  The geophysical data indicate several strong ground EM conductors on the east side of Highway 955 in the Patterson Conductor Corridor.  The conductors appear to have been disrupted by non-conductive structures crossing them. The breaks in the conductors are also associated with a magnetic low that could be interpreted as an alteration feature. This sector of the Patterson Conductor Corridor lies about 3 kms northeast from the centre of the boulder field where some of the larger boulders were located. 
The drill hole data available include geological logs and down-hole radiometric surveys. One hole, CLU-12-79 on the north side of the target area, showed two short intervals of sharply anomalous radioactivity in the basement rocks intersected. This hole also has a thicker section of regolith than other holes in the area which may reflect local hydrothermal alteration. These observations suggest possible proximity to mineralization.
The Patterson Conductive Corridor runs along the boundary zone between the Clearwater and Western Granulite Domains. According to assessment reports submitted by SMDC, the Crown Corporation predecessor company of Cameco (TSX:CCO), this is interpreted to have had a favourable geological history, analogous to the highly productive Wollaston Domain along its boundary with the Mudjatik Domain in the East Athabasca Basin.
