ESO Discovers New Uranium and Gold Zone at Marietta Property Staking Completed

VANCOUVER, Sept. 22, 2011 /CNW/ - ESO Uranium Corp. (TSX-V: ESO), (the "Company" or "ESO") carried out a geological mapping and portable rock drill sampling programme of a large area of outcrop on the Marietta property in April 2011. Rock samples were recovered from depths up to 1.8 m (6 feet) to obtain an initial evaluation of the bulk grade potential of uranium in the intrusive rocks hosting multiple veins and veinlets, some of which carry uranium, gold, silver and copper mineralization.  A new uranium and polymetallic target was located during this work, lying on ground that is next to the Marietta Claims and within the area of influence of the Marietta option agreement. Staking has been recently completed to include this prospect in the Marietta property.

The Marietta property lies South of Hawthorne Nevada, West of the Mono Lake Crater in California, and totals approximately 2,400 acres (970 hectares) in West Central Nevada, near the old mining town of Mina.

A 30 m wide zone. was discovered containing a series of parallel quartz veins, individually up to 40 cm wide, with areas of off-scale radioactivity (>9,999 counts per second as measured by hand held Exploranium GR-110G total count gamma-ray scintillometer), and uranium secondary minerals. This zone is located approximately 120 m (396 feet) north of the original property boundary.

A preliminary grab sample, MR11-37, was recovered from one of these quartz veins, and returned 0.294% uranium, 10.99 g/t gold, 7.2 g/t silver, 0.485% lead, and 0.224% zinc. An additional six lode claims were staked to include MR11-37 within the Marietta property.  Structural measurements indicate that these quartz veins, exposed on the surface in the newly staked claims, dip steeply south, which is further into ESO's Marietta property. Following a short programme of systematic sampling, it is expected that this would be a drill ready target, with road access, to check extensions to depth.

Six samples of drill cuttings were recovered with the portable rock drill on a copper prospect that had been discovered in an earlier work programme within the southwest corner of the Marietta property.  Copper oxide mineralization is hosted in a rhyolitic tuff unit exposed for approximately 50 m (165 feet) along a road with a cut bank that is up to 4 m (13 feet) high.  These samples returned 13 ppm to 1.65% copper, and 0.5 to 26.3 g/t silver from drilled depths of up to 1.5 m (5 feet).  The existing road represents an easily permitted drill site to test the continuity of copper oxide mineralization.

The Marietta property was first mined for polymetallic ores in the late 1800's. Shear structures up to a few meters in width were the principal sources of the ore mined and these carried bornite with silver and gold values and oxide copper.. After World War II it was discovered that these high grade ores carried uranium values and were hosted in a radioactive granitic intrusive.

Analyses were carried out by American Assay Laboratories, which is an independent ISO 17025 certifiable assay laboratory located in Sparks, Nevada.  A 69 element analysis was carried out using a four acid digestion followed by ICP analysis.  Any ICP gold results above detection limits were subsequently fire assayed as a 30 gram aliquot of the original pulp, and the fire assay bead was measured gravimetrically.
