Introduction

The Ed Rose group of six (6) claims adjoins the north end of the

west boundary of Agnew Lake Mines In Hyman Township, Ontario. The attached

map shows the location.

The claim group was surveyed to determine whether anomalous

amounts of radon gas were present In the soil cover. About 19,900 feet of

flagged line was surveyed between October 18 and November 3, 1975-

Location and Access

The six-claim group Is located In Hyman Township, Ontario, about

6,000 feet west of the shaft on the Agnew Lake Mines property. John Creek

crosses the claim group In a relatively deep valley.

Property

The property consists of six (6) claims In Hyman Township, Ontario,

numbered as follows:

S 35968** S 359685

l S 359686 1 S 35968? t S 359688 t S 359689

Geology, Mineralization and History

The claims are underlain by Huronian sediments, mainly quartzite

and minor argil)He. John Creek Is probably underlain by an ENE-striklng

fault. Basement Archaean granite outcrops at or near the west boundary

of the group. The southern boundary of the group Is underlain by poly

mictic conglomerate. A NNW-strlking diabase dyke cuts across the central

part of the claims. Within a few hundred feet of the dyke are a few narrow

and short uranlferous showings which have been diamond drilled by previous

holders of the claims without finding significant amounts of uranium.

Programme

Survey lines were cut, chained and flagged In a nortf.-south

direction at ^00-foot intervals. Radon gas measurements were taken at

100-foot intervals and at 50-foot intervals on each side of readings con

sidered to indicate possible anomalous conditions. Areas of outcrop, marsh-

swamp, and creek could not be surveyed.

Background counts averaged 10 counts per minute (c.p.m.); soil

gas counts greater than 20 c.p.m. plus background were considered anomalous.

Field data were plotted by the geological students who carried

out the survey-Michael McGowan, Leonid Koff, and Robert Gilman. The map

was drafted by Peter Stralendorff. The map shows the instrument reading at

the end of the first minute on the right of the line and the ratio-percent

of the third minute reading to the first minute reading plotted to the left

of the line. A ratio of greater than 50^ indicates a uranium source; a

lower value indicates thorium.

Survey Technique

The technique detects and measures alpha radiation associated

with radon In soil gas utilizing a Portable Radon Detector, Model RD-200,

manufactured by E.D.A. 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-RO-200) was based on

an original design carried out by Atomic Energy of Canada Ltd. in cooperation

with the Geological Survey of Canada.

Radon gas consists mainly of two isotopes Radon 222 and Radon 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

emission 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

emission to Polonium 216 (see attached Sheet 8).

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

ticles 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-lives.

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

foil gas is circulated back into an alpha-sensitive zinc sulphate 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.
