There are several interesting targets which
are associated with the main magnetic feature located
within this survey area. The best targets for ground
investigation are those numbered 15 and 27. Both of
these zones exhibit excellent conductivity and have
direct magnetic correlation. Both of these conductors
demand ground work. The other conductors that are
associated with this strong magnetic feature should
also be investigated as it is apparent that all of
these zones have their origin in bedrock.
The following is a discussion of the conductors^
and recommendations are given as to the order of the
ground work.
Conductors ftl to ft8
All of these conductors exhibit poor conductiv
ity and it is felt that a low priority be given to these
with regard to ground follow-up.
Conductor #9
This weak E.M. response is associated with a
sharp magnetic feature and for this reason ground work
should be carried out.
Conductor ft]O
This weak conductor is associated with a magnetic
high which adds interest. Magnetite could possibly be
the cause of the E.M. anomaly. A low priority is given
to the anomaly.
Conductor Jill
A low priority is given to this weak conductor
which exhibits only fair conductivity.
This basement conductor is associated with the
prominent magnetic feature. Sulphides could possibly
be the cause of this conductor and the recommended sec
tions for ground work are from intercepts 37 C to 47 A.
A high priority is given.
Conductor #3:3
This weak conductor is situated at the nose of
a magnetic high. A moderate priority is given to this
short conductor, and it is felt that ground work should
definitely be carried out while work is being done on
the other conductors in the vicinity.
Conductor #14
Good conductivity is exhibited by the intercepts
of this short conductor which has direct magnetic corre
lation. Sulphides could be the cause and therefore a
high priority is given.
Conductor #15
This zone is on strike with conductor #14 and
a high priority is again given to this conductor. Inter
cept 60 F exhibits excellent conductivity and it is felt
that sulphides are the cause. This is a top priority
target.
Conductors #16 and #17
Both of these conductors are weak and exhibit
poor conductivity. They exist on the north and south
flanks of the magnetic feature, and they may reflect
some minor sulphides or graphite within a contact zone.
A low priority is given.
Moderate to poor conductivity is shown by the
intercepts along this conductor, but it is apparently
a basement conductor as it is associated with a magnetic
high. Minor amounts of sulphides or magnetite could be/
possibly,the cause of the conductor. Ground work on a
moderate priority is suggested.
Conductor #19
This long conductor varies in strength and con
ductivity along its strike. Ground work should be done
on sections of this conductor at places where good con
ductivity is exhibited and where there is good magnetic
correlation. Suggested intercepts to cover are 71 C,
72 B, and 76 D.
Conductor #20
This short isolated conductor should be consider
ed in a ground programme because of its isolation, short
strike length and moderate magnetic correlation. The con
ductivity of the conductor is fair.
Conductor #21
Magnetite or a serpentized peridotite could be
the cause of this conductor. The intercepts along this
zone exhibit poor conductivity and there is a high magnetic
correlation with the zone. A low priority is given.
Conductors #22 to #25
All of these conductors exhibit poor conductivity
and these are not considered to be good targets for base
metal possibilities. Low priority is given to these con
ductors.
r j[26
This y,one i s comprised of several short weak
conductors. Poor conductivity is exhibited by the in
tercepts and therefore a low priority is given.
Conduetor #27
Excellent conductivity is shown by intercept 91 C
and ground work should definitely be done to cover this
particular intercept. The magnetic correlation with the
intercepts lead one to suspect that pyrrhotite is the
cause. A high priority is given.
Conductors #28, #29, and #3O
These three long conductors are outside of the
claim block and therefore adequate coverage does not ex
ist. Good conductivity is, however, exhibited by the
intercepts of conductors #28 and #29, and they definitely
have their origin in the basement rocks.

The aircraft arc equipped with Mark V INPUT
airborne K. M. systems and Barringer AM-101 proton pre
cession magnetometers. APN-1 radio altimeters are used
for vertical control. The outputs of these instruments
together with fiducial timing marks are recorded by means
of galvanometer type recorders using light sensitive pa
per. Thirty-five mm continuous strip cameras are used to
record the actual flight path.
(I) MA RK V INPUT SYSTEM
The Induced Pulse Transient (INPUT) system is
particularly well suited to the problems of overburden
penetration. Currents are induced into the ground by
means of a pulsed primary electromagnetic field which is
generated in a transmitting loop around the aircraft. By
using half sine wave current pulses and a loop of large
turns-area, the high output, power needed for deep pene
tration is achieved.
The induced current in a conductor produces
a secondary electromagnetic field which is detected and
measured after the termination of each primary pulse. De
tection is accomplished by means of a receiving coil towed
behind the aircraft on five hundred feet of cable, and
the received signal is processed and recorded by equipment
in the aircraft. Since the measurements are in the time
domain rather than the frequency domain common to contin
uous wave systems/ interference effects of the primary trans
mitted field are eliminated. The secondary field is in the
form of a decaying voltage transient originating in time
at the termination of the transmitted pulse. The amplitude
of the transient is, of course, proportional to the amount
of current induced into the conductor and, in turn, this
current is proportional to the dimensions, the conductivity
and the depth beneath the aircraft.
(ii)
The rate of decay of the transient is inverse
ly proportional to conductivity. By sampling the decay
curve at six different time intervals, and recording the
amplitude of each sample, an estimate of the relative con
ductivity can be obtained. By this means, it is possible
to discriminate between the effects due to conductive near-
surface materials such as swamps and lake bottom silts, and
those due to genuine bedrock sources. The transients due
to strong conductors such as sulphides exhibit long decay
curves and are therefore commonly recorded on all six chan
nels. Sheet-like surface materials, on the other hand,
have short decay curves and will normally only show a re
sponse in the first two or three channels.
The samples, or gates, are positioned at 300,
500, 700, 1100, 1500 and 1900 micro-seconds after the ces
sation of the pulse. The widths of the gates 'are 200, 300,
400, 600, 600, and 600 micro-seconds respectively.
For homogeneous conditions, the transient decay
will be exponential and the time constant of decay is equal
to the time difference at two successive sampling points
divided by the log ratio of the amplitudes at these points.
(II) BARRINGER AM-101A PROTON PRECESSION MAGNETOMETER
The AM-101A magnetometer which measures the to
tal magnetic field has a sensitivity of 5 gammas and a
range from 20,000 gammas to 100,000 gammas.
Because of the high intensity field produced
by the INPUT transmitter, the magnetometer results are re
corded on a time-shciring basis. The magnetometer head is
energized while the transmitter is on, but the readout is
obtained during a short period when the transmitter is off.
Using this technique, the head is energized for 1,15 seconds
and then the transmitter is switched off for 0.15 seconds
while the precession frequency is being recorded and convert
ed to gammas. Thus a magnetic reading is taken every 1.3
seconds.
Uii)
The syii. .Is us. to designate the anomalies
are shown in the l' end on jach map sheet, and the anoma
lies on -ich line . e lett., .-od in alphabc ical order in
the di, action of f jht. '.l'. :ir locations ,,re plotted with
reference to the fie ;cial numbers on the visicorder record.
A sample record is included at the end of the
report identifying the method used to correct for the pos
ition of the E.M. "Bird" and identifies the parameters on
each channel. Occasionally, a question mark may be shown
alongside the anomaly symbol. This may occur when the res
ponse is very weak and there is some doubt as to whether or
not it is caused by turbulence or compensation noise caused
by large changes in the position of the "bird" relative to
the aircraft.
All the anomaly locations, magnetic correlations,
and the amplitudes of channel number 4 are listed on the
data sheets accompanying the final maps.
GENERAL INTERFERE TAT I ON
The INPUT system will respond to conductive over
burden and near-surface horizontal conducting layers in ad
dition to bedrock conductors. Differentiation is based on
the rate of transient decay, magnetic correlation and the
anomaly shape together with the conductor pattern and topo
graphy.
Power lines sometimes produce spurious anomalies
but these can be identified by reference to the monitor
channel.
Railroad and pipeline responses are recognized
by studying the film strips.
Graphite or carbonaceous material exhibits a wide
range of conductivity. When long conductors without magne
tic correlation are located on or parallel to known faults
or photographic linears, graphite is most likely the cause.
Contact zones can often be predicted when anom-
(iv)
aly trends coincide with the lines of maximum gradient
along a flanking magnetic anomaly. It is unfortunate that
graphite can also occur as relatively short conductors and
produce attractive looking anomalies. With no other inform
ation than the airborne results, these must be examined on
the ground.
Serpentized peridotites often produce anomalies
with a character that is fairly easy to recognize. The
conductivity which is probably caused in part by magnetite,
is fairly low so that the anomalies often have a fairly
large response on channel #1; they decay rapidly, and they
have strong magnetic correlation. INPUT E.M. anomalies
over massive magnetites show a relationship to the total
Fe content. Below 2 5-3Q%, very little or no response at
all is obtained but as the percentage increases the anoma
lies become quite strong, with a characteristic rate of de
cay which is usually greater than that produced by massive
sulphides.
Commercial sulphide ore bodies are rare, and
those that respond to airborne survey methods usually have
medium to high conductivity. Limited lateral dimensions
are to be expected and many have magnetic correlation caused
by magnetite or pyrrhotite. Provided that the ore bodies
do not occur within formational conductive zones as mention
ed above, the anomalies caxised by them will usually be re
cognized on an E.M. map as priority targets.

INTRODUCTION
This report contains our interpretation of
the results of an airborne electromagnetic survey
and magnetic survey flown in the Winisk River Area,
Ontario, on February 23, 1971. A brief description
of the survey procedure together with recommendations
for ground follow-up is included.
The survey totalled 55 line miles and was per
formed by Questor Surveys Limited. The survey air
craft was a .Super Canso CF-JMS and the operating base
was Winisk^ Ontario.
The area outline is shown in a 1:250,000 map
at the end of this report. This is part of the Nation
al Topographic Series sheet, number 43 L.
MAP COMPILATION
The base maps are uncontrolled mosaics con
structed from National Air Photo Library l" s2 l mile
photographs. These mosaics were reproduced at a scale
o ^ l" ~ 1320' on stable transparent film from which
white prints can be made.
Flight path recovery was accomplished by com
parison of the prints of the 35 mm film with the mosaic
in order to locate the fiducial points. These points
are approximately one mile apart.
SURVEY PROCEDURE
Terrain clearance was maintained as close to
A&Q feet ag j)osjgj.ble. with the E.M. "bird" at approxi
mately 150 fe-ct,JgibovG.affie ground. A normal S-pattern
flight path using approximately one mile turns was used.
The equipment operator logged the flight details and
monitored the instruments.
A line s^p.a,oJing^c^j^^^^p^j-^^sgcj, f
'J'hcro arc many conductors indicated on the
INPUT map and some of those arc outside of the claim
block. All of the conductors eire discussed below and
no regard has been given to the claim boundary. It
is felt that all of these conductors have their source
in bedrock and therefore all of them should be consid
ered in a ground follow-up programme. Some, however,
should be given more emphasis than others. The conduct
ors that should be given f j.rst consideration are those
conductors numbered 14, 15, 16, 17, and 19.
These five conductors all exhibit good conduct
ivity and are associated with what is believed to be an
iron foundation. Sulphides; could be the cause of these
conductors and therefore they should be considered as
top priority targets. The following discussion of the
various zones is offered as a guide to priorities when
investigating the conductors on the ground.
9.S 10. Low priority ratings are given to both of these
conductive zones.
11. This strong zone exhibits good conductivity and
exists along the flank of a strong magnetic feature.
Portions of this conductor should be investigated as it
is apparent that the cause of the conductor is graphite
and/or sulphides.
12. Intercepts 21 C and 22 C are possible indications
of a ground conductor axis. These were selected as anom
alies because there is an inflection of the INPUT traces
between the responses of the stronger zones to the north
and south of conductor #12. If this conductor is valid,
it is probably an extension of conductor #13 and it could
be investigcited at the same time.
13. Due to the strong conductors to the south, good
resolution of this zone did not result. Fair to poor
conductivity is exhibited by the anomaly intercepts with
in the zone.
14. Good conductivity is shown by the anomalies along
this trend which exists along the flank of a strong mag
netic feature (iron formation). The strike length of
approximately 3,000 feet adds interest. Ground work on
a high priority basin is recommended.
15. 'J'he axis of conductor #15 is situated along the
peak of the iron formation. Good conductivity is shown
by the intercepts and it is felt that this conductor is
caused by sulphides associfited with the iron formation.
Ground work is definitely warranted on this conductor
and the obvious portions of the conductor to sample are
the centres of the magnetic highs.
16.&17. These two conductors are parallel to conductor #15
and flank the major magnetic peak. Good conductivity is
shown by these conductors and these should be investigated
on the ground on a high priority basis. Sulphides could
be the cause.
18. This conductor is poorly defined due to the in
fluence of conductor #15. Conductor #18 has moderate con
ductivity and is considerably weaker than conductor #15.
Ground work on a moderate priority is recommended.
19. In some sections along the strike of conductor #19
the anomaly intercepts are poorly defined on the early
channels but as the anomaly persists through to the sixth
channel, better definition is achieved. This is seen on
intercept 38 D which exemplifies a bedrock conductor; in
this case, a basement conductor below surface conductivity.
Good conductivity is shown by the responses along this
trend and ground work from intercept 26 D to 32 C is recom
mended. Sulphides could be the cause.
20. This conductor parallels zone #19 and the west end
is stronger than zone #19, but the conductivity of conduc
tor #20 is not as good as that shown by conductor #19.
This zone, however, should be investigated and it could
be incorporated in the same grid as conductor #19.
21.-25. All of these conductors are weaker zones than
those that are associated with the iron formation (i.e.
conductors #11 to #20). It is felt, however, that these
arc basement conductors and they could load to some
interesting targets.

For homogeneous conditions, the transient decay

DA'IV^PRKSKNTATI ON
The symbols used to designate the anomalies
are shown in the legend on each map sheet, and the anoma
lies on each Hine arc lettered in alphabetical order in
the direction of flight. Their locations are plotted with
reference to the fiducial numbers on the visicorder record.
A sample record is included at the end of the
report identifying the method used to correct for the pos
ition of the E.M. "Bird" and identifies the parameters on
each channel. Occasionally, a question mark may be shown
alongside the anomaly symbol. This may occur when the res
ponse is very weak and there is some doubt as to whether or
not it is caused by turbulence or compensation noise caused
by large changes in the position of the "bird" relative to
the aircraft.
All the anomaly locations, magnetic correlations,
and the amplitudes of channel number 4 are listed on the
data sheets accompanying the final maps.
GENERAL INTERPRETATION
The INPUT system will respond to conductive over
burden and near-surface horizontal conducting layers in ad
dition to bedrock conductors. Differentiation is based on
the rate of transient decay, magnetic correlation and the
anomaly shape together with the conductor pattern and topo
graphy.
Power lines sometimes produce spurious anomalies
but these can be identified by reference to the monitor

Railroad and pipeline responses are recognized

Graphite or carbonaceous material exhibits a wide

Contact zones can often be predicted when anom-
aly trends coincide with the lines of maximum gradient

graphite can also occur as relatively short conductors and

ation than the airborne results, these must be examined on
the ground.
Serpentized peridotites often produce anomalies
with a character that is fairly easy to recognize. The
conductivity which is probably caused in part by magnetite,
is fairly low so that the anomalies often have a fairly
large response on channel #1; they decay rapidly, and they
have strong magnetic correlation. INPUT E.M. anomalies
over massive magnetites show a relationship to the total
Fe content. Below 25-30?;, very little or no response at
all is obtained but as the percentage increases the anoma
lies become quite strong, with a characteristic rate of de
cay which is usually greater than that produced by massive
sulphides.
Commercial sulphide ore bodies are rare, and
those that respond to airborne survey methods usually have
medium to high conductivity. Limited lateral dimensions
are to be expected and many have magnetic correlation caused
by magnetite or pyrrhotite. Provided that the ore bodies
do not occur within formational conductive zones as mention
ed above, the anomalies caused by them will usually be re
cognized on an E.M. map as priority targets.
