Report on
Radiometric Survey
Gaudette Township Property
Sault Ste. Marie Mining Division, Ontario
for
Dongas Explorations 6- Holdings Limited
SUMMARY
The Company holds six mining claims in
Gaudette Township, three-quarters of a mile east
of the Artlstan molybdenum property. This property
produced molybdenum during World War II. Recent*
magnetometer and geological surveys covered the Dengas
property. No showings or workings were located.
Radiometric surveys were carried out in order to
determine If the granite of the claim group contains
uranium. The results of this survey were negative.
It la recommended that the claims should be
held and developments watched on the adjoining Artlstan
property.
Report on
Radloraetrlo Survey
Gaudette Township Property
Sault Ste.Marie Mining Division,Ontario

Donga* Explorations S- Holdings Limited
I. INTRODUCTION
Dengas holds a group of six mining claims
adjoining the Artlatan Property near Searchmont, Ontario.
Magnetometer and geological surveys were carried out over
the property. Under wartime conditions, J*0 tons of
molybdenum ore was produced. Uranium was also noted
In the area. A radiometric survey was carried out over
the claim group to assess the uranium potential.
II. PROPERTY. LOCATION AND ACCESS
The property conslts of six contiguous un-
patented mining claims situated In the southeast quarter
of Gaudette Township numbered as follows i
SSM 282926 -31 Inclusive (six claims) 40 acres each240 acres (approx.)
The Whitman Dam Road Is an all-weather
gravel road running from Searchmont on the Algoma
S SM-1
Central Railway northeastward across the corner of the
property to Whitman Dam on the Goulals River. A bush
road forma the east boundary of the property. A
single outcrop area takes the form of a 150 foot hill.
III. GENERAL GEOLOGY
The area la mapped undlfferentlated granitic
and syenetlc rocks. No mineral has been recorded on
this property. A mile east on the property of Artlstan
Mining and Milling a small but Impressive molybdenum
occur rance la known.
IV. ECONOMIC GEOLOGY
Within the gneisses a four foot wide quart*
vein, conformable with the flat lying gneisses, occurs
on the Artlstan property. The greater part of the
pyrite, chalcopyrite and molybdenum mineralization occurs
In the gneissic material between the quart* string*-'H that
make up the quartz vein. Molybdenum showings occur
over a two mile radius from the Artistan property. The
Dengas property Is separated from the Artlstan properties
by about three-quarters of a mile of overburdened ground.
No mineral occurrances were located on the Dengas pro
perty.

V. RECENT WORK^ MMMWMM^^^MVM^nMMNMMM^BHMM t
During July 1975 a radiometric , spectrometer
s'urvey^waa carried out over the property.
Discussion of Results
The apeotrometer survey was carried out with
a McPhar T.V.II. A description of the Instrument Is
settingIn the appendix. The background value of
was 7 x 10 or 70 counts per minute over the outcrop
area and 3 to 8 x 10 {or 30-60) counts per minute
over the overburden areas. There are no anomalous
uranium-thorium or thorium readings on the survey.
The geological survey revealed that the out
crops on the property are restricted to the hill area
centred on claims 282930 and -31. This hill Is mainly
hornblende granite gneiss. A diabase dyke was mapped
corresponding to a magnetic anomaly striking northwest
across claim 282930.
VI. CONCLUSIONS AND RECOMMENDATIONS
The spectrometer survey does not reveal any
anomalous uranium-thorium or thorium conditions.
It Is recommended that no further work be
carried out on the property. If during the coming
•--
year there are encouraging developments on the Artlstan
property to the west, the property could be further
explored.

GENERAL DESCRIPTION AND APPLICATIONS
The gamma ray detecting principle Iles In the
sodium Iodide crystal. Gamma rays entering the crystal,
Interact with the crystal atoms, resulting In free electrons
and light emission. The optically coupled photomultipller
converts the light emission to electrical pulses. The
magnitudes of the electrical pluses bear a relationship to
the energy levels the Intercepted gamma rays.
Various radioactive elements have characteristic
pamma energy speotruma. The nature of the spectrum
for a given element can be used to advantage in identifying
it In the presence of other radioactive elements.
Thorium emits gamma rays with energy levels
exceeding 2.5 Mev. The highest energy radiation from
potassium Is about 1.6 Mev. The three vertical lines
marked Tlt Tg, and T^ show the location of the threshold
settings of the TV-1 scintillometer after the instrument
has been calibrated. Threshold T- at 2.5 Mev. allowsj a
only those electrical pulses to be registered whose amplitudes
correspond to gamma rays with energy levels above 2.5 Mev.
T 2 similarly responds to gair.ma energy levels above 1.6 Mev.
When both thorium and urarJum are present during a measure
ment, then the reading at T g contains counts resulting from
both elements whereas T~ contains counts from thorium
#v
It Is possible then, to subtract the count due
to thorium In the T. reading, leaving the count from
uranium only. The count representing thorium in the T2
reading is a fixed multiple of the T- reading. In the
TV-1 scintillometer, this multiple is 3.5. That is, the
count in T2 due to uranium Is T2-3*5 T-. A thorium
calibrating source and calibration procedure, provided with
the Instrument, ensures that this Is always the case.
Once the count in Tp has been resolved into
net cout for uranium, it is possible to arrive at a
. quantitative estimate of the material grade.
