JV partners Alpha Minerals Inc. and Fission Energy Corp. report repeated radon success at Patterson Lake South in the Athabasca Basin. Drilling on new radon anomalies continues to return good intersections and discover new zones.

For details see 2013 press release for Fission Uranium Corp. and numerous more recent press releases.

I have been researching and promoting the use of radon and radium geochemistry in lake and stream water and sediments for many years. See my earlier note recommending lake-bottom radon for drill-target location.

In 1972 I delineated a radon anomaly in the south arm of Midwest Lake, above the orebody, which was discovered by drilling several years later. If the water in Midwest Lake had been a few feet higher the boulder train would have been submerged and not detected by the scintillometer, but the radon anomaly would have been there.

In 1974 my team discovered a similar anomaly in the lakes at the Kiggavik deposit, expressed by radon and uranium in water and radium and uranium in sediment. Again, if the surface exposure had been covered by a foot or two of overburden or lake water our airborne gamma-ray survey wouldn't have found it, but the geochemical survey would have.

(Brief note on possible confusion of radon and radium: The press releases above refer to radon in sediment. I sometimes refer to this same thing as radium because radium is the source of the radon measured by the instruments.)


In all three cases, Midwest, Kiggavik and now PLS, if the melting ice sheet had left a slightly different arrangement of lakes, swamps and overburden, then the gamma radiation of surface exposures and boulder trains would not have been detected, but the orebody could still have been found by radon in the lakes.

INSTRUMENTS
  • We measure: radon - radium - thoron - radon daughters - alpha radiation.
  • The Lucas cell is recognized as the most sensitive and reliable method for these elements.
  • Intrinsically safe functions.
  • Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
  • immune to beta and gamma radiation.
  • one monitor works with a number of (less expensive) detectors.
  • Our instruments are used around the world in exploration for uranium, oil & gas, groundwater and hydrothermal, and in environmental protection, health physics, earthquake prediction, and evaluation of hydrocarbon and NAPL contamination etc.
  • Same instruments used for radon and radium in soil, sediment, plant parts, rocks, water, soil gas, air, snow, food, and for radon and thoron daughters in air.
  • Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
  • In the radon business since 1968, our instruments are updated regularly with the most recent major re-design in 2015. Modern, low-power, field-rugged electronics. Some earlier versions still working after 40 years.
  • Continuous real-time monitoring and data recording.
  • RS232 port/pc software.
  • User programmable measurement intervals, sample and count periods and alarm level settings.
  • Can work in a tent without electricity or be carried from point to point in the field.
  • 50 readings per day. Results available immediately.
  • Portable. Rechargeable battery pack good for a long day in the field and recharges in a few hours.
  • Can be operated by junior personnel if carefully supervised.
  • EPA and CE Mark compliant.
