INTRODUCTION

Eighteen (l 8) claims of about 50 acres each were staked on Lots 29, 30, 31, 32, 33 Concession Vll, Lots 29, 30, 31 Concession V111 and the South half of Lots 32, 33 Concession V111, of Anstruther Township.

The claims are located in the southern portion of the Bancroft camp and were surveyed by the Radon Gas Method to outline possible uraniferous pegmatite zones.

Page 3: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

LOCATION AND ACCESS

The property is located one-half mile west of Highway 28, and four miles north of the town of Apsley. A bush access road leads close to the property.

The topography is rolling with a western central flooded area; relief is about 100 feet.

Page 4: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

GEOLOGY AND MINERALIZATION

Precambrian grenville metasediments consisting of limestones and paragneisses are intruded by granite pluton stocks. Uraniferous pegmatitic granite dykes could occur along the eastern contact of the large granite intrus i ve.

Programme

Survey lines were cut, chained, and flagged in a north - south

direction on 1*00 foot centres. Soil gas measurements were taken at 100

foot intervals, with anomalous zones reduced to 50 foot intervals over the

width of the zone. Areas of outcrop, marsh-swamp, and lakes could not be

surveyed.

Background counts both in soil and air averaged between 10 and 20

counts per minute. Readings are plotted as net counts per minute (i.e.

first minute reading minus atmospheric background). Met counts greater than

50 are considered anomalous.

Page 6: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

Survey Technique

The technique detects and measures alpha radiation associated with Radon

in soil gas utilizing a Portable Radon Detector, model RD200, manufactured

by EDA Electronics Ltd. of Ottawa, Ontario. Long known and used in Europe,

the technique was introduced into Canada by the Geological Survey of Canada

in 1968. The present system (EDA-RD-200) was based on an original design

carried out by Atomic Energy of Canada Ltd. in co-operation with the

Geological Survey of Canada.

Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220.

Radon 222 is the sixth member of the disintegration series of Uranium 238

(see attached sheet A). With a half life of 3.82 days, it decays by alpha

emmission to Polonium 218. Radon 220 is the fifth member of the disintegration

series of Thorium 232, which decays with a half life of 5^-5 seconds by

alpha omission to Polonium 216 (see attached sheet B).

The RD-200 is a scintillometer that detects and counts alpha-particles

over a pre-set period (usually three minutes), so that it is possible to

detect radiation sources obscured by overburden, as well as differentiating

a Uranium source from Thorium on the basis of respective longer and shorter

half-1 i ves.

The soil gas method is rapid and easy and requires that overburden

be present to trap soil gas below or at the humus cover. The operation

involves augering a hole in the ground and using a tube and bulb pump; the

soil gas is circulated back into an alpha-sensitive zinc sulphide cell.

This cell is coupled with the scintillometer that counts the alpha

particles on a pre-set one minute sequence for a three minute period.

The advantage of this technique over previously and better known

gamma-ray geiger and scintillometer surveys is that gamma-rays associated with

the decay of Uranium, Thorium, and Potassium isotopes are easily masked

by overburden and therefore only effective to bedrock exposures.

Page 7: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

RESULTS AND CONCLUSIONS

Radon anomalies interrupted by swamps showing rough linearity in a north-south direction probably correlate with pegmatite zones.

Geological follow-up is recommanded.

INTRODUCTION

Six (6) claims of about 50 acres each were staked on Lots 38, 39 Concession XIV, south half Lots 38, 39 Concession XV of Anstruther Township.

The claims are located in the southern portion of the Bancroft camp and were surveyed by scintillometer to outline possible uraniferous pegmatite zones.

Page 10: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

LOCATION AND ACCESS

The property is situated on the south shore of Eels Lake and Eels Creek flows north-south through the claim group. A gravel road some two miles long leads north of Highway 28 to the area.

The topography is hilly with some swamps; relief is about 100 feet.

Page 11: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

GEOLOGY AND MINERALIZATION

Precambrian grenville metasediments consisting of limestones and paragneiss are intruded by granite pluton stocks. Uraniferous pegmatitic granite dykes occur along a north-south to north-east strike.

Page 12: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

Programme il

Survey lines were cut, chained, and flagged in an east - west

direction at ^00 foot line intervals. Total count gamma ray scintillometer

readings were taken at 100 foot and 50 foot stations.

Background counts are in the order of 25 counts per second and

readings greater than 50 are considered anomalous.

As overburden restricts passage of gamma rays from a bedrock

source to surface, outrcrop areas are noted on the survey plan.

Page 13: RADON GAS SUR GRP B - Ontario€¦ · Radon gas consists mainly of two isotopes: Radon 222 and Thoron 220. Radon 222 is the sixth member of the disintegration series of Uranium 238

Survey Technique

An Exploranium Mods! G.R.S.-101 Total Count Scintillometer was used

as the survey instrument.

The instrument contains a 1.25" X 1.0" sodium iodide crystal that

converts gaTima rays into faint flashes of light v/hose brilliance is

proportional to the energy level of the gamma rays measured. The light

flashes are. detected by a photomul tipl ier tube, and averaged by a ratemeter

c'rcuit in counts per second.

The frequency or signal count reflects the intensity of all gamma

ray energy above an energy level of 0.05 Mev (millions electron volts) and

as such indicates the isotope group consisting of Uranium 238, Thorium

232, and Potassium ^0.

In practice, the instrument is highly sensitive and experience has

indicated the following "correlation between counts and approximate gradet

of U308 equivalent:

50 - 100 0.1 to 0.3iOO - 200 0.3 to 0.7200 - 300 0.7 to 1.5300-500 l.5 to 3.0

RESULTS AND CONCLUSIONS

A radioactive pegmatite appears to be present with claims 422^35 and k22^38.

Geological examination is recommended.
