Conductor C; Conductor C is the ^ueterly continuation of Conductor.
B ond was picked up un linet 2W to 36Ui. Tho lo to high frequency
ratios indicate good conductivity and the intensity of the

axis le generally parallel to the trend of the magnetic contours
in the immediate area.

because of itB location ot tha ends of linea ra Bd from Transmitter

Dn tha hnsio of tha naQnatic data it ia concluded that

Comiuctora A, Q, and C are budrock conductors af potential
economic significance. 'i .Conductor A occurs along e metavolctinic-ultramnf lo

EUCTRPHAGMETIC SURVEY
Any alternating magnetic field will induce an alactrictl
eddy currant in the Medium through uhich the Magnetic field
paaaea. If a source of an alternating magnetic field ia located
near s conductive body anomaloualy atrong 0ddy currente will be
induced in the dapoait due to ita high electrical conductivity.
Electrical currents induced in the conductive body will produce
a secondary magnetic field proportional to the intanalty of currant
flow.. .' i " '. f
A reeaivar coil tuned to the frequency of the tranamit-
tlng device will pick up both the directly tranamitted algnal and
tho eddy currant aignal.

INTRODUCTION
During the period December 5 to December B, a magneto
meter aurve\, wae carried ciut on tha property of Dome-Babine Mines
Limited, 2DU1 flour, Guineas Tower, 1055 UeBt Hastings Street,
Vancouver,1, B.C., by Shield Geophysics Limited.
The property consists of 11 contiguous, unpatented
mining claims numbered as follows: P9B561 to P9B56B inclusive,
P101192, P10193, and P1QUOB. Claims P9B561 to 9B56B inclusive ,
are recorded in the name of A. Theriault, 150 Third Avenue,
Timmins, Ontario, claims P101192 and 101193 ara recorded in the
name of M. Lochapelle, ^39 Wilson Avenue, Timmins, Ontario and
P10UOB is recorded in the name of E. Mord, 9B-B Norman Street,
Timmins, Ontario,
A totel of 1659 stations were established on 16.9 miles
of picket linos. A Sharpe M.F.-1 fluxgate magnetometer was used
for the survey, ,. ; .
The linecutting was dons by Ingemar Explorations Limited,
362 Seventh Avenue, Timmins, Ontario.
LtiCATI.tJN AND ACCESS
The property is located in the south-central part of
Carman Township, Porcupine Mining Division near the Carman-
Langmuir township boundary. Access to the property is either via
a winter roed from South Porcupine or via air from South Porcupine
Lake to Nighthawk Lake, a distance of approximately ten miles.
PRtVIOUS UuRK , - ,, ,
Claim f 90561 was partly covered by a magnetic survey
done by Dominion Gulf, No other work, other than geological
mapping by government agencies, hBB been carried out on the property.

GEOLOGY UF THE PROPERTY .
The geology of Carmen Township and of the Daroe-Sabina
property is presented on Ontario Department of Minna Preliminary
Map P.356.
The property occurs on the south limb of an Bast-northeast
erly trending anticlinal structure that crosses the central aector
of Carmen Township. The property ia underlain by intermediate to
felsic metavolcanic rocks and iron formation that have been intruded
by peridotite and dunite Bills. Diabase dikes cut the ultra*
mafic intrusive and the metavolcanic rocks. Post-diabase faulting
occurs along tuo major strike directions. Older faults having an
BBSt-northeaat strike direction are offset by younger faults
having a northwesterly atrike direction.
No mineralization of economic significance outcrops on the
property. Some minor asbestos occurs in the serpentinized ultra
mafic rocks.
RESULTS DF THL MAGNETIC SURl/LY, f. i, ' ' -.
The survey was carried out using a Sharpe M,F ( 1 fluxgate
magnetometer (6ec Appendix 1 for 1 instrument data). The results
of the survey are presented on thjB attached map (in pocket).
The magnetic background on the property is 1500 tp 20130
gammas. The magnetic relief is approximately ^0,000 gammas
(155 to ^0,000 gammas).
The interpretation of the results is difficult in that
there ia no definite correlation of magnetic highs with areas
known to be underlain by ultramafic rocks and magnetic loys with
areas known to be underlain by intermediate to felsic matovoloanic
- 3 -
rocks. Fnr example the magnetic low in the southwest corner of the
property is underlain by outcrops of felsic metavolcanic rocks
whereas the magnetic low south of the baseline in the line 2kU to
28U area ia underlain by ultramafic rocks.
The interpretation of the magnetic results has been based
on known geological data from D.D,M. Preliminary Hap P.356. Where
no geological data ia available, magnetic highs are assumed to
reflect underlying ultramafic rocka and magnetic lDUB are assumed
to reflect underlying felsic to intermediate metavolcanlc racks.
The central part of the property ie underlain by ultra
mafic rocks that hove intruded the metavolcanic rocke. The local
magnetic highs within the area inferred to be underlain by ultra
mafic rocks are believed to be due to concentrations of magnetite
formed during the process of serpentinization of the ultramafic
rocks. The cause of .the magnetic louis in the central part of the
'.li 1 . . .
area is not known. - ,
A zona of faulting having a northwesterly strike direction
has been inferred in the east part of the property. Strike Slip
movement would appear to be approximately 600 feet In a left-hand
direction. The magnetic high that parallels the fault zone along
the northeast boundary of the fault zone is believed to be due to
concentrations of magnetite formed during shear-imposed serpen*
tinization.
A parallel fault has been inferred to cross the southwest
part of the property due to the abrupt termination of the iron
formation inferred in that area.
An older fault having an easterly strike has been inferred
to cross the central part of the property.
- f* - '.:; ; .-
This fault IB baaed on offsetting of the magnetic highs end the
presence of an electromagnetic conductor parallel to the baseline
between linsa 6W to 36UI.
CONCLUSIONS AND REGDMMENDflTIDNS
The property l a underlain by intermediate to feleic weta-
volcanic rocks that have been intruded by ultramafic rocks. A zone
of iron formation has been inferred in the southwest sector of
the property. i , ;
The magnetic aurvay has aided in the interpretation of
the knouin geological data, has outlined the local extent of the
ultramafic rocks and has indicated the presence of a number of feult
zones.
It is rBcamrnnndnd that a vertical loop electromagnetic
survey be carried out with the objective of testing the property!
particularly those areae underlain by metsvDlcanic-ultremafic
intrusive rock contacts, for the possible presence of sulphide ;
mineralization* :" ;
It IB recommended that additional lines be cut in the east
part of the property. The lines should be cut in an east-ueet ,
direction and ahould run fron line 12U to the east property boundary*

INSTRUMENT DATA AND SURVEY METHOD
MAGNETOMETER SURVEY
A Sharpe M.F,-1 fluxgate magnetometer uaa used in the
magnetic survey. This instrument measurae the vertical component
of the earth's magnetic field in gammaa. Base stations for de
termining the magnetic diurnal variations mere eatabliahed along
the main base line at 100 foot intervals. Magnetic readings were
taken at 50 foot intervale, along the cross lines.
