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.

We measure: radon - radium - thoron - radon daughters - alpha radiation.
is recognized as the most sensitive and reliable method for these elements.
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.
In the radon business since 1968, our latest major instrument update was 2015.
Modern, low-power, field-rugged electronics. Some earlier versions still working after 35 years.
Continuous real-time monitoring and data recording.
Winter and summer, from the Sahara Desert to the Canadian Shield, our instruments have faced up to severe field conditions.
- Intrinsically safe functions.
Sensitive to geochemical trace levels necessary for radon in lake water and for radon-thoron isotope ratios.
Can work in a tent without electricity or be carried from point to point in the field.
50 readings per day. Results available immediately.
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.
Same instruments used for radon and radium in soil, sediment,
plant parts, rocks, water, soil gas, air, and snow, and for radon daughters in air.
- EPA compliant.
