VANCOUVER, April 25, 2012 /CNW/ - 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
DRILL HOLE SUMMARY - Gamma Probe Radioactive Intervals
|DDH #||Depth to||Downhole Gamma (>500 cps)|
|Basement (m)||From (m)||To (m)||Width (m)||CPS Avg||CPS max|
*"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 uranium mineralization.
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.
