Drill follow up of anomalous radon at the bottom of the snow led to the McClean Lake North Uranium Discovery.

Our radon detectors are based on the Lucas cell,

  • Sensitive to radon thoron ratios
  • Sensitive to low levels of radon for radon in lake water
  • Basis of EPA Method 903.1 for radium in water.
  • Instant results at the sample site for follow up

A drill hole in the centre of a strong radon anomaly
intersected 33 feet of 7.51% U3O8 at 500 feet depth

  • The Radon survey was carried out with alphameters placed under the snow.
  • Although the ore-grade mineralization was at 500 feet, anomalous uranium was observed at much shallower depths. This near surface mineralization may have given rise to the radon anomaly observed at surface.
  • This information and the attached figure were taken from Saracoglu,N; Wallis,R.H.; Brummer,J.J.; and Golightly,J.P. 1983: Canadian Mining and Metallurgical Bulletin, vol. 76, No. 852.
  • Alphameters have the advantage that they remain at the sample site and collect data over a period of days, averaging out any temporal variations.
  • Our instruments have the advantage of instant results at the sample site, with the possibility of immediate follow-up and checking.
  • Our instruments also determine thoron, and the Rn/Tn ratio is important in recognising false anomalies due to soil permeability. link.
