VANCOUVER, April 25, 2012 /PRNewswire/ – ESO Uranium Corp. (TSXV: ESO), (the “Company” or “ESO”) is very pleased to announce that
it has drilled three more holes with elevated radioactivity. Drill
holes PLS12-014 to -016 all intersected strongly anomalous gamma
radiation values based on down-hole gamma logging and hand held
scintillometer analysis on the Patterson Lake (PLS) Joint Venture (JV)
claims – 50% interest with Fission Energy Corp (TSX-V: FIS) also 50%.
The same conductor was intersected by drill hole PLS12-013 850 m. from
PLS12-016. (News Release 04/18/2012 “DRILLING RETURNS 19.5 METERS OF STRONG RADIOACTIVE MINERALIZATION”)
-- All three drill holes intersected zones of radioactivity that included significant widths of higher gamma radiation. -- Drill hole PLS12-016 had the best average radioactivity which averaged 2516 cps* over 4.45 meters (14.7 feet) with a maximum value of 6032 cps. -- Drill hole PLS12-015 had 1.95 m @ 662 cps in Mesozoic clastic sediments at 94.59 m. -- Drill hole PLS12-016 had 0.25 m @710 cps in Devonian clastics at 54.96 m. -- These are the widest sections of significant radioactive mineralization believed to have been reported in the Patterson Lake Conductor Corridor to date. -- The drill holes are located along about 850 meters strike length of a graphitic conductor with cross-cutting structures causing several flexures of this conductor. -- Strong clay and chlorite alteration of drill core from radioactive intersections -- Accessible by road - 2 kms from all weather Highway 955 Cluff Lake Mine road

*”cps” stands for “counts per second” due to total counts gamma
radiation measured by a Mt Sopris 2PGA-1000 borehole probe. All
intersections are drill intersections and not necessarily true widths.
Drill hole PLS12-015 located between -013 and -016 is of particular
interest since a coarse clastic sedimentary bed immediately above the
basement rocks shows a 1.95 m. interval averaging 662 cps in the
down-hole gamma log with a peak value of 1259 cps. Drill hole
PLS12-016 also has a 0.25 m. section 2.12 m above the basement rocks.
This appears to be radioactive material, excavated from basement or
Athabasca sediments, that has been deposited in much younger rocks
immediately above the Archaean basement rocks. This suggests that
there may be a uranium source in Archaean basement rocks closer to
these drill holes than the other holes drilled in this program.
The programme was extended from the 14 holes, originally reported, to 16
drill holes for this phase of the work which will now pause for a short
time during break-up. This will allow full review of new geophysical
data that fills in an area on land that was completed when higher soil
moisture allowed better electrical connectivity. Samples have been
submitted for PIMA analysis to evaluate the nature of the clay
alteration and geochemical analysis of the cores will be undertaken to
assist in setting priorities for drilling in the next months.
The target mineralization sought on the PLS property is a shallow
subcropping body (or bodies) of high grade uranium, being the source of
the high grade uranium boulders located in 2011.
ESO reports Mt Sopris down-hole gamma probe values during the early
stages of uranium exploration drilling to be consistent. The Company
has done so in all other projects involving a drill program. The
down-hole probing is a method that samples a larger volume of rock than
the drill core. It captures radiation due to mineralization in the rock
some inches outside the diameter of the drill hole. The hand held GR
110 scintillometer is a critical tool for checking core for
radioactivity quickly as it is delivered to surface and examined for
This is very important for the quicker recognition of significant
mineralization so that the site geologist can determine if drilling
should be continued because of success in entering radioactive
mineralization in drill core from the current depth of the hole. It is
most important also for safety reasons, namely, allowing the early
segregation of radioactive cores from low background radioactive cores.
Since the gamma probe is typically run down the hole at the completion
of a drill hole, and since, in some cases, the rapid visual inspection
of drill core at the drill site could miss recognition of radioactive
minerals, the use of the handheld is an important insurance tool. The
data generated by both approaches are a valid measure of the actual
radioactivity of the drill core. Occasionally there may be washing out
of radioactive clay material from core or lack of core recovery that
could result in a difference between hand held scintillometer results
and those of the down-hole gamma probe.
The handheld used in this work is subject to the cautionary note below
since it is a “total counts” measuring device.
All holes were radiometrically surveyed with a 2PGA-1000 natural gamma
probe. The reader is cautioned that a total counts gamma probe reading is the
result of natural gamma radiation that may come from various sources
including cosmic radiation, thorium, potassium and uranium and its
radioactive decay products. CPS (counts per second) values cannot be
certain to correlate with uranium grades of the rock but are a general
guide of the radioactivity of minerals present in rock placed in
proximity to the instrument.
