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.

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

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

Page 8: REPORT ON RADIOMETRIC SURVEY, GAUDETTE TOWNSHIP …...Donga* Explorations S- Holdings Limited I. INTRODUCTION Dengas holds a group of six mining claims adjoining the Artlatan Property

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.
