1. INTRODUCTION

lll

l This report describes an airborne geophysical survey

m carried out on behalf of Tundra Gold Mines Limited by

Aerodat Limited. Equipment operated included a 3

l frequency electromagnetic system, a VLF-EM system, and

a magnetometer.

The survey was flown on March 26 to March 29, 1983

l from an operations base at Wawa Ontario. A total of

541 line miles were flown, at a nominal line spacing of

660 feet. Of the total flown, this report describes

l 334.4 line miles.

3.1 Aircraft

l The helicopter used for the survey was an Aerospatial

H Astar 350D owned and operated by North Star Helicopters.

Installation of the geophysical and ancillary equipment

l was carried out by Aerodat. The survey aircraft was

flown at a nominal altitude at 60 meters.

3.2 Equipment

3.2.1 Electromagnetic System

The electromagnetic system was an Aerodat/

M Geonics 3 frequency system. Two vertical

coaxial coil pairs were operated at 955 and

g 4130 Hz and a horizontal coplanar coil pair

at 4500 Hz. The transmitter-receiver separa-

' tion was 7 meters. In-phase and quadrature

l signals were measured simultaneously for the

3 frequencies with a time-constant of 0.1

g seconds. The electromagnetic bird was towed

30 meters below the helicopter.

3.2.2 VLF-EM System

The VLF-EM System was a Herz 2A. This instru-

J ment measures the total field and vertical

l

quadrature component of two selected frequencies.

The sensor was towed in a bird 15 meters below

the helicopter.

The sensor aligned with the flight direction

l is designated as "LINE" , and the sensor

perpendicular to the line direction as "ORTHO" .

J The "LINE" station used was NAA, Cutler Maine,

- 17.8 KHz or NLK, Jim Creek Washington, 24.8 KHz.

The "ORTHO" station was NSS, Annapolis Maryland,

M 21.4 KHz. The NSS transmitter was operating on

a very limited schedule and was not available

j during a large part of the survey.

l 3.2.3 Magnetometer

l The magnetometer was a Geometrics G-803 proton

precession type. The sensitivity of the

J instrument was l gamma at a 1.0 second sample

rate. The sensor was towed in a bird 15 meters

" below the helicopter.

l 3.2.4 Magnetic Base Station

J An IFG proton precession type magnetometer was

operated at the base of operations to record

diurnal variations of the earths magnetic

field. The clock of the base station was

synchronized with that of the airborne system

3-3

ll *l to facilitate later correlation.

l 3.2.5 Radar Altimeter

l A Hoffman HRA-100 radar altimeter was used to

record terrain clearance. The output from the

J instrument is a linear function of altitude

for maximum accuracy.

3.2.6 Tracking Camera

A Geocam tracking camera was used to record

J flight path on 35 mm film. The camera was

operated in strip mode and the fiducial numbers

" for cross reference to the analog and digital

l data were imprinted on the margin of the film.

m 3.2.7 Analog Recorder

A RMS dot-matrix recorder was used to display

" the data during the survey. A sample record

l with channel identification and scales is

presented on the following page.

4. DATA PRESENTATION

l l l 4.1 Base Map and Flight Path Recovery

l The base map photomosaic at a scale of 1/15,840 was

m constructed from available aerial photography. The

flight path was plotted manually on this base and

l digitized for use in the computer compilation of the

maps. The flight path is presented with fiducials

for cross reference to both the analog and digital

data.

l l l

l

4-2

4.2 Electromagnetic Profile Maps

l The electromagnetic data was recorded digitally at

a high sample rate of 10/second with a small time

m constant of 0.1 second. A two stage digital filtering

m process was carried out to reject major sferic events,

and reduce system noise.

Local atmospheric activity can produce sharp, large

l amplitude events that cannot be removed by conventional

filtering procedures. Smoothing or stacking will reduce

l their amplitude but leave a broader residual response

H that can be confused with a geological phenomenon. To

avoid this possibility, a computer algorithm searches

out and rejects the major "sferic" events.

The signal to noise was further enhanced by thelapplication of a low pass filter. The filter was

l applied digitally. It has zero phase shift which

prevents any lag or peak displacement from occurring

and it suppresses only variation with a wavelength

B less than about 0.25 seconds. This low effective time

constant permits maximum profile shape resolution.

Following the filtering processes, a base level

l correction was made. The correction applied is a linear

function of time that ensures that the corrected

l amplitude of the various inphase and quadrature components

l

l l

l l

l

l

l

is zero when no conductive or permeable source is

present. This filtered and levelled data was then

presented in profile map form.

The in-phase arid quadrature responses of the coaxial

955 Hz configuration are plotted with the flight

path and presented on the photomosaic base.

The in-phase and quadrature responses of the coaxial

l 4500 Hz and the coplanar 4130 Hz configuration are

plotted with flight path and are available as a two

colour overlay.

4.3 Magnetic Contour Maps

l The aeromagnetic data was corrected for diurnal

variations by subtraction of the digitally recorded

i base station magnetic profile. No correction for

H regional variation is applied.

m The corrected profile data was interpolated onto a

regular grid at a 2.5 nun interval using a cubic

l spline technique. The grid provided the basis for

threading the presented contours at a 10 gamma

l interval.

l 4.5 Electromagnetic Conductor Symbolization

l The electromagnetic profile maps were used to

identify those anomalies with characteristics

l typical of bedrock conductors. The in-phase

mm and quadrature response amplitudes at 4130 Hz

were digitally applied to a phasor diagram for

l the vertical half-plane model and estimates of

conductance (conductivity thickness) were made.

l The conductance levels were divided into categories

mm as indicated in the map legend; the higher the number,

the higher the estimated conductivity thickness

l product.

U As discussed in Appendix I the conductance should be

used as a relative rather than absolute guide to

m conductor quality. A conductance value of less than

2 mhos is typical for conductive overburden material

" and electrolytic conductors in faults and shears.

B Values greater than 4 mhos generally indicate some

electronic conduction by certain metallic sulphides

l and/or graphite. Gold, although highly conductive,

is not expected to occur in sufficient concentration

l

l

l

to directly produce an electromagnetic anomaly;

however, accessory mineralization such as pyrite or

l l l

4-7

graphite can produce a measurable response.

l With the aid of the profile maps, responses of similar

characteristics may be followed from line to line and

m conductor axes identified.

J The distinction between conductive bedrock and over-

burden anomalies is not always clear and some of

the symbolized anomalies may not be of bedrock origin.

l It is also possible that a response may have been

mistakenly attributed to overburden and therefore not

l included in the symbolization process. For this reason,

B as geological and other geophysical information becomes

available, reassessment of the significance of the

l various conductors is recommended.

APPENDIX I

GENERAL INTERPRETIVE CONSIDERATIONS

l l l Electromagnetic

l The Aerodat 3 frequency system utilizes 2 different

m transmitter-receiver coil geometries. The traditional

coaxial coil configuration is operated at 2 widely

l separated frequencies and the horizontal coplanar coil

pair is operated at a frequency approximately aligned

with one of the coaxial frequencies.

l The electromagnetic response measured by the helicopter

m system is a function of the "electrical" and "geometrical"

properties of the conductor. The "electrical" property

l of a conductor is determined largely by its conductivity

and its size and shape; the "geometrical" property of the

B response is largely a function of the conductors shape and

B orientation with respect to the measuring transmitter and

receiver.

lElectrical Considerations

lFor a given conductive body the measure of its conductivity

l or conductance is closely related to the measured phase

shift between the received and transmitted electromagnetic

H field. A small phase shift indicates a relatively high

l conductance r a large phase shift lower conductance. A

small phase shift results in a large in-phase to quadrature

l

lm 9 - 2 - APPENDIX I

l ratio and a large phase shift a low ratio. This relation

ship is shown quantitatively for a vertical half-plane

m model on the accompanying phasor diagram. Other physical

B models will show the same trend but different quantitative

relationships.

The phasor diagram for the vertical half-plane model, as

l presented, is for the coaxial coil configuration with the

amplitudes in ppm as measured at the response peak over

B the conductor. To assist the interpretation of the survey

M results the computer is used to identify the apparent

conductance and depth at selected anomalies. The results

J of this calculation are presented in table form in Appendix I

and the conductance and in-phase amplitude are presented

" in symbolized form on the map presentation.

l

l

The conductance and depth values as presented are correct

only as far as the model approximates the real geological

situation. The actual geological source may be of limited

l length, have significant dip, its conductivity and thickness

may vary with depth and/or strike and adjacent bodies and

B overburden may have modified the response. In general the

B conductance estimate is less affected by these limitations

than the depth estimate but both should be considered a

J relative rather than absolute guide to the anomalies

properties.

l l l l l l l l l l l l l l l l l l l

- 3 - APPENDIX I

Conductance in mhos is the reciprocal of resistance in

ohms and in the case of narrow slab like bodies is the

product of electrical conductivity and thickness.

Most overburden will have an indicated conductance of less

than 2 mhos; however, more conductive clays may have an

apparent conductance of say 2 to 4 mhos. Also in the low

conductance range will be electrolytic conductors in faults

and shears.

The higher ranges of conductance, greater than 4 mhos,

indicate that a significant fraction of the electrical

conduction is electronic rather than electrolytic in nature.

Materials that conduct electronically are limited to certain

metallic sulphides and to graphite. High conductance

anomalies, roughly 10 mhos or greater are generally limited

to sulphide or graphite bearing rocks.

Sulphide minerals with the exception of sphalerite, cinnabar

and stibnite are good conductors; however, they may occur

in a disseminated manner that inhibits electrical conduction

through the rock mass. In this case the apparent conductance

can seriously under rate the quality of the conductor in

geological terms. In a similar sense the relatively non

conducting sulphide minerals noted above may be present in

significant concentration in association with minor conductive

l- 4 - APPENDIX I

sulphides, and the electromagnetic response only relate

to the minor associate mineralization. Indicated conductance

is also of little direct significance for the identification

of gold mineralization. Although gold is highly conductive

it would not be expected to exist in sufficient quantity

to create a recognizable anomaly but minor accessory sulphide

mineralization could provide a useful indirect indication.

In summary the estimated conductance of a conductor can

provide a relatively positive identification of significant

sulphide or graphite mineralization; however^ a moderate

to low conductance value does not rule out the possibility

of significant economic mineralization.

Geometrical Considerations

Geometrical information about the geologic conductor can

often be interpreted from the profile shape of the anomaly.

The change in shape is primarily related to the change in

inductive coupling among the transmitter, the target, and

the receiver.

In the case of a thin, steeply dipping, sheet-like conductor,

the coaxial coil pair will yield a near symmetric peak over

the conductor. On the other hand the coplanar coil pair will

pass through a null couple relationship and yield a minimum

over the conductor, flanked by positive side lobes. As the

dip of the conductor decreases from vertical, the coaxial

lM ^ - 5 - APPENDIX I

l anomaly shape changes only slightly, but in the case of

the coplanar coil pair the side lobe on the down dip side

l strengthens relative to that on the up dip side.

J As the thickness of the conductor increases, induced

current flow across the thickness of the conductor becomes

B relatively significant and complete null coupling with the

l coplanar coils is no longer possible. As a result, the

apparent minimum of the coplanar response over the conductor

l diminishes with increasing thickness, and in the limiting

m case of a fully 3 dimensional body or a horizontal layer

or half -space, the minimum disappears completely.

A horizontal conducting layer such as overburden will produce

l a response in the coaxial and coplanar coils that is a

function of altitude (and conductivity if not uniform) . The

l profile shape will be similar in both coil configurations

g with an amplitude ratio (coplanar/coaxial) of about 4/1.

In the case of a spherical conductor, the induced currents

m are confined to the volume of the sphere, but not relatively

l restricted to any arbitrary plane as in the case of a sheet-

l

l

like form. The response of the coplanar coil pair directly*

over the sphere may be up to 8 times greater than that of

the coaxial coil pair.

l l - 6 - APPENDIX I

l In summary a steeply dipping, sheet-like conductor will

display a decrease in the coplanar response coincident

l with the peak of the coaxial response. The relative

m strength of this coplanar null is related inversely to

the thickness of the conductor? a pronounced null indicates

l a relatively thin conductor. The dip of such a conductor

can be infered from the relative amplitudes of the side-lobes,

Massive conductors that could be approximated by a conducting

l sphere will display a simple single peak profile form on both

M coaxial and coplanar coils, with a ratio between the coplanar

to coaxial response amplitudes as high as 8.*

Overburden anomalies often produce broad poorly defined

l anomaly profiles. In most cases the response of the coplanar

coils closely follow that of the coaxial coils with a

J relative amplitude ratio of 4.*

l Occasionally if the edge of an overburden zone is sharply

defined with some significant depth extent, an edge effect

l will occur in the coaxial coils. In the case of a horizontal

m conductive ring or ribbon, the coaxial response will consist

of two peaks, one over each edge; whereas the coplanar coil

l will yield a single peak.

l lll l l l l l l l l l l l l l l l

- 7 - APPENDIX I

* It should be noted at this point that Aerodat's definition

of the measured ppm unit is related to the primary field

sensed in the receiving coil without normalization to the

maximum coupled (coaxial configuration). If such normal

ization were applied to the Aerodat units, the amplitude

of the coplanar coil pair would be halved.

l l l l l l l l l l l l l l l l l l l

- 8 - APPENDIX J

Magnetics

The Total Field Magnetic Map shows contours of the

total magnetic field, uncorrected for regional varia

tion. Whether an EM anomaly with a magnetic correla

tion is more likely to be caused by a sulphide deposit

than one without depends on the type of mineralization.

An apparent coincidence between an EM and a magnetic

anomaly may be caused by a conductor which is also

magnetic, or by a conductor which lies in close proximity

to a magnetic body. The majority of conductors which are

also magnetic are sulphides containing pyrrhotite and/or

magnetite. Conductive and magnetic bodies in close

association can be, and often are, graphite and magnetite.

It is often very difficult to distinguish between these

cases. If the conductor is also magnetic, it will usually

produce an EM anomaly whose general pattern resembles

that of the magnetics. Depending on the magnetic perme

ability of the conducting body, the amplitude of the

inphase EM anomaly will be weakened, and if the conduc

tivity is also weak, the inphase EM anomaly may even be

reversed in sign.

lg W - 9 - APPENDIX I

l VLF Electromagnetics

l The VLF-EM method employs the radiation from powerful

military radio transmitters as the primary signals.

g The magnetic field associated with the primary field

g is elliptically polarized in the vicinity of electrical

conductors. The Herz Totem uses three coils in the X.

l Y. Z. configuration to measure the total field and

vertical quadrature component of the polarization

l ellipse.

l The relatively high frequency of VLF 15-25 KHz provides

g high response factors for bodies of low conductance.

" Relatively "disconnected" sulphide ores have been found

l to produce measurable VLF signals. For the same reason,

poor conductors such as sheared contacts, breccia zones,

l narrow faults, alteration zones and porous flow tops normally

m produce VLF anomalies. The method can therefore be used

effectively for geological mapping. The only relative dis-

I advantage of the method lies in its sensitivity to conductive

overburden. In conductive ground the depth of exploration

l is severely limited.

g The effect of strike direction is important in the sense

p of the relation of the conductor axis relative to the

energizing electromagnetic field. A conductor aligned

8 along a radius drawn from a transmitting station will be

l

lI - 10 - APPENDIX I

B in a maximum coupled orientation and thereby produce a

stronger response than a similar conductor at a different

m strike angle. Theoretically it would be possible for a

B conductor, oriented tangentially to the transmitter to

produce no signal. The most obvious effect of the strike

B angle consideration is that conductors favourably oriented

with respect to the transmitter location and also near

perpendicular to the flight direction are most clearly

8 rendered and usually dominate the map presentation.

B The total field response is an indicator of the existence

and position of a conductivity anomaly. The response will

J be a maximum over the conductor, without any special filtering,

and strongly favour the upper edge of the conductor even in

the case of a relatively shallow dip.

8 The vertical quadrature component over steeply dipping sheet

m like conductor will be a cross-over type response with the

cross-over closely associated with the upper edge of the

l conductor.

B The response is a cross-over type due to the fact that it

is the vertical rather than total field quadrature component

l that is measured. The response shape is due largely to

m geometrical rather than conductivity considerations and

the distance between the maximum and minimum on either side

l of the cross-over is related to target depth. For a given

target geometry, the larger this distance the greater the

lm W - 11 - APPENDIX I

B depth.

m The amplitude of the quadrature response, as opposed

to shape is function of target conductance and depth

J as well as the conductivity of the overburden and host

* rock. As the primary field travels down to the conductor

" through conductive material it is both attenuated and

l phase shifted in a negative sense. The secondary field

produced by this altered field at the target also has an

l associated phase shift. This phase shift is positive and

g is larger for relatively poor conductors. This secondary

field is attenuated and phase shifted in a negative sense

l during return travel to the surface. The net effect of

these 3 phase shifts determine the phase of the secondary

l field sensed at the receiver.

l A relatively poor conductor in resistive ground will yield

g a net positive phase shift. A relatively good conductor

* in more conductive ground will yield a net negative phase

l shift. A combination is possible whereby the net phase

shift is zero and the response is purely in-phase with no

l quadrature component.

J A net positive phase shift combined with the geometrical

cross-over shape will lead to a positive quadrature response

* on the side of approach and a negative on the side of

l departure. A net negative phase shift would produce the

reverse. A further sign reversal occurs with a 180 degree

l

l - 12 - APPENDIX I

m change in instrument orientation as occurs on reciprocal

line headings. During digital processing of the quad-

I rature data for map presentation this is corrected for

by normalizing the sign to one of the flight line headings,
