SUMMARY

A DIGHEM111 survey was flown for Noranda Exploration

Company Limited, over the Shebandowan area in Ontario. The

survey comprised approximately 2620 line-km.

The purpose of the survey was to detect conductive

zones, and to map the magnetic properties of the rock units

within the survey area.

Numerous bedrock conductors were detected by the

electromagnetic survey. Some of these appear to correlate

with magnetic anomalies. The 7200 Hz coplanar EM data were

used to generate contour maps of the apparent resistivity.

These show the conductive properties of the survey area. The

total field and calculated vertical gradient magnetics yield

valuable information about the geology and bedrock structure.

The VLF data show numerous, moderately strong trends, some of

which may reflect bedrock structure or stratigraphy.

The survey area exhibits potential as host for both

conductive massive sulphide deposits and weakly conductive

zones of disseminated mineralization. A comparison of the

various geophysical parameters, compiled with geological and

geochemical information, should be useful in selecting

targets for follow-up work.

SUBYE5LBQUIPMENT

This section provides a brief description of the

geophysical instruments used to acquire the survey datai

Electromagnetic System

Modeli DIGHEM111

Type* Towed bird, symmetric dipole configuration, operated at a nominal survey altitude of 30 metres. Coil separation is 8 metres.

Coil orientations/frequencies i coaxial f 9 00 Hzcoplanar/ 900 Hzcoplanar/ 7,200 Hz

Sensitivity: 0.2 ppm at 900 Hz0.4 ppm at 7,200 Hz

Sample rate: 10 per second

The electromagnetic system utilizes a multi-coil

coaxial/coplanar technique to energize conductors in

different directions. The coaxial transmitter coil is

vertical with its axis in the flight direction. The coplanar

coils are horizontal. The secondary fields are sensed

simultaneously by means of receiver coils which are maximum

coupled to their respective transmitter coils. The system

yields an inphase and a quadrature channel from each

transmitter-receiver coil-pair.

- 2-2 -

Magnetometer

Model i Picodas Cesium

Sensitivity: 0.01 nT

Sample rate t 10 per second

The magnetometer sensor is towed in a bird 15 m below

the helicopter.

Magnetic Base Station

Model i Geometrics G-826A

Sensitivity! 0.50 nT

Sample rate: once per 5 seconds

An Epson recorder is operated in conjunction with the

base station magnetometer to record the diurnal variations

of the earth's magnetic field. The clock of the base station

is synchronized with that of the airborne system to permit

subsequent removal of diurnal drift.

VLF System

Manufacturer: Herz Industries Ltd.

Type: Totem-2A

Sensitivity: Q.1%

- 2-3 -

The VLF receiver measures the total field and vertical

quadrature components of the secondary VLF field. Signals

from tvo separate transmitters can be measured

simultaneously. The VLF sensor is towed in a bird 10 m

below the helicopter.

Radio Altimeter

Manufacturer i Honeywell/Sperry

Type: AA 220

Sensitivity: l m

The radio altimeter measures the vertical distance

between the helicopter and the ground. This information is

used in the processing algorithm which determines conductor

depth.

Analog Recorder

Manufacturer: RMS Instruments

Type: GR33 dot-matrix graphics recorder

Resolution: 4x4 dots/mm

Speed: 1.5 mm/sec

The analog profiles were recorded on chart paper in the

aircraft during the survey. Table 2-1 lists the geophysical

data channels and the vertical scale of each profile.

- 2-5 -

Digital Data Acquisition System

Manufacturer: RMS

Type: DAS8

Tape Deck: RMS TCR-12, 6400 bpi, tape cartridge recorder

The digital data were used to generate several computed

parameters.

Tracking Camera

Type: Panasonic Video

Model: AG 2400/WVCD132

Fiducial numbers are recorded continuously and are

displayed on the margin of each image. This procedure

ensures accurate correlation of analog and digital data with

respect to visible features on the ground.

Navigation System

Model: Del Norte 547

Type: UHF electronic positioning system

Sensitivity: l m

Sample rate: 0.5 per second

The navigation system uses ground based transponder

stations which transmit distance information back to the

helicopter. The ground stations are set up well away from

- 2-6 -

the survey area and are positioned such that the signals

cross the survey block at an angle between 30* and 150*.

After site selection, a baseline is flown at right angles to

a line drawn through the transmitter sites to establish an

arbitrary coordinate system for the survey area. The onboard

Central Processing Unit takes any two transponder distances

and determines the helicopter position relative to these two

ground stations in cartesian coordinates. These are

transformed into a known coordinate system (such as UTM)

during processing.

Aircraft

The instrumentation was installed in an Aerospatiale

AS350B turbine helicopter. The helicopter flew at an average

airspeed of 110 km/h with an EM bird height of approximately

30 m.

PRODUCTS AND PROCESSING TECHNIQUES

The following products are available from the survey

data. Those which are not part of the survey contract may be

acquired later. Refer to Table 1-2 for a summary of the

maps which accompany this report and those which are

recommended as additional products. Most parameters can be

displayed as contours/ profiles, or in colour.

Base Maps

Base maps of the survey area were prepared from 1150,000

topographic maps. These were enlarged photographically to a

scale of 1:20,000.

Flight Path

The cartesian coordinates produced by the electronic

navigation system were transformed into UTM grid locations

during data processing. These were tied to the UTM grid on

the base map.

Prominent topographical features on the flight videos

are correlated with the navigational data points, to check

that the data accurately relates to the base map.

- 3-2 -

Electromagnetic Anomalies

Anomalous electromagnetic responses are selected and

analysed by computer to provide a preliminary electromagnetic

anomaly map. This preliminary EM map is used, by the

geophysicist, in conjunction with the computer generated

digital profiles, to produce the final interpreted EM anomaly

map. This map includes bedrock, surficial and cultural

conductors. A map containing only bedrock conductors can be

generated, if desired.

Resistivity

The apparent resistivity in ohm-m may be generated from

the inphase and quadrature EM components for any of the

frequencies, using a pseudo-layer halfspace model. A

resistivity map portrays all the EM information for that

frequency over the entire survey area. This contrasts with

the electromagnetic anomaly map which provides information

only over interpreted conductors. The large dynamic range

makes the resistivity parameter an excellent mapping tool.

EM Magnetite

The apparent percent magnetite by weight is computed

wherever magnetite produces a negative inphase EM response.

The results are usually displayed on a contour map.

- 3-3 -

Total Field Magnetics

The aeromagnetic data are corrected for diurnal

variation using the magnetic base station data. The regional

IGRF gradient is removed from the data, if required under the

terms of the contract.

Enhanced Magnetics

The total field magnetic data are subjected to a

processing algorithm. This algorithm enhances the response

of magnetic bodies in the upper 500 m and attenuates the

response of deeper bodies. The resulting enhanced magnetic

map provides better definition and resolution of near-

surface magnetic units. It also identifies weak magnetic

features which may not be evident on the total field

magnetic map. However, regional magnetic variations, and

magnetic lows caused by remanence, are better defined on the

total field magnetic map. The technique is described in more

detail in Section 5.

Magnetic Derivatives

The total field magnetic data may be subjected to a

variety of filtering techniques to yield maps of the

following!

- 3-4 -

vertical gradient

second vertical derivative

magnetic susceptibility with reduction to the pole

upward/downward continuations

All of these filtering techniques improve the

recognition of near-surface magnetic bodies, with the

exception of upward continuation. Any of these parameters

can be produced on request. Dighem's proprietary enhanced

magnetic technique is designed to provide a general

"all-purpose" map, combining the more useful features of the

above parameters.

VLF

The VLF data can be digitally filtered to remove long

wavelengths such as those caused by variations in the

transmitted field strength. The results are usually

presented as contours of the filtered total field.

j Digital Profiles

Distance-based profiles of the digitally recorded

geophysical data are generated and plotted by computer.

These profiles also contain the calculated parameters which

are used in the interpretation process. These are produced

- 3-5 -

as worksheets prior to interpretation, and can also be

presented in the final corrected form after interpretation.

The profiles display electromagnetic anomalies with their

respective interpretive symbols. The differences between the

worksheets and the final corrected form occur only with

respect to the EM anomaly identifier.

Contour. Colour and Shadow Map Displays

The geophysical data are interpolated onto a regular

grid using a cubic spline technique. The resulting grid is

suitable for generating contour maps of excellent quality.

Colour maps are produced by interpolating the grid down

to the pixel size. The distribution of the colour ranges is

normalized for the magnetic parameter colour maps, and

matched to specific contour intervals for the resistivity and

VLF colour maps.

Monochromatic shadow maps are generated by employing an

artificial sun to cast shadows on a surface defined by the

geophysical grid. There are many variations in the shadowing

techniques. The various shadow techniques may be applied to

total field or enhanced magnetic data, magnetic derivatives,

VLF, resistivity, etc. Of the various magnetic products, the

- 3-6 -

shadow of the enhanced magnetic parameter is particularly

suited for defining geological structures with crisper images

and improved resolution.

SURVEY

GENERAL DISCUSSION

Tables 4-1 to 4-3 summarize the EN responses on the

electromagnetic anomaly maps with respect to conductance

grade and interpretation.

The electromagnetic anomaly maps show the anomaly

locations with the interpreted conductor type, dip,

conductance and depth being indicated by symbols. Direct

magnetic correlation is also shown if it exists. Bedrock

conductors are indicated by the interpretive symbols "D"

(for thin dikes) or "B" (for other conductor geometries).

Surficial conductors are identified by the interpretive

symbol "S". An "H" interpretive symbol is used to indicate a

broad or flat-lying conductive unit that appears to be

situated at some depth below surface. This may be due to

either bedrock or surficial sources. An anomaly due to the

edge of a broad conductor is given an "E" designation. The

interpretive symbol "L" is used to indicate a line source

such as a power line, or other response due to culture.

The anomalies shown on the electromagnetic anomaly maps

are based on a near-vertical, half plane model. This model

best reflects "discrete" bedrock conductors. Wide bedrock

conductors or flat-lying conductive units, whether from

surficial or bedrock sources, may give rise to very broad

anomalous responses on the EN profiles. These may not

appear on the electromagnetic anomaly maps if they have a

regional character rather than a locally anomalous character.

These broad conductors, which more closely approximate a half

space model, will be maximum coupled to the horizontal

(coplanar) coil-pair and should be more evident on the

resistivity parameter. The resistivity maps, therefore, may

be more valuable than the electromagnetic anomaly maps, in

areas where broad or flat-lying conductors are considered to

be of importance. Contoured and colour resistivity maps,

prepared from the 7200 Hz coplanar data are included with

this report.

Excellent resolution and discrimination of conductors

was accomplished by using a fast sampling rate of 0.1 sec and

by employing a common frequency (900 Hz) on two orthogonal

coil-pairs (coaxial and coplanar). The resulting "difference

channel" parameters often permit differentiation of bedrock

and surficial conductors, even though they may exhibit

similar conductance values. The inphase and quadrature

difference channels are displayed on the digital profiles.

Zones of poor conductivity are indicated where the

- 4-6 -

inphase responses are small relative to the quadrature

responses. Where these responses are coincident with strong

magnetic anomalies, it is possible that the inphase

amplitudes have been suppressed by the effects of magnetite.

Most of these poorly-conductive magnetic features give rise

to resistivity anomalies which are only slightly below

background. If it is expected that poorly-conductive

economic mineralization may be associated with magnetite-rich

units, most of these weakly anomalous features will be of

interest. In areas where magnetite causes the inphase

components to become negative, the apparent conductance

values may be understated and the calculated depths of EN

anomalies may be erroneously shallow.

Resistivity

Apparent resistivity maps were prepared from the 7200 Hz

coplanar EN data. These maps show the conductive properties

of the survey area.

Power lines in the survey area have severely affected the

resistivity contours. A herringbone pattern is evident in

the contours in blocks C and D. This is due to the different

angles of ascent and descent, depending on survey line

direction, as the helicopter crosses the power line. This

- 4-7 -

effect is common near large, high-voltage power lines.

There are also gaps in the middle of the grid in which no

resistivity data was calculated. This occurs where ground

effect has been lost due to the bird height required to cross

a power line. These gaps occur in narrow fiducial ranges in

the following line ranges: 21400 to 21440, 21450 to 21490,

21570 to 21640, 21780 to 21790, 30410 to 30470 and 30570 to

30620.

Some of the resistivity anomalies correlate with magnetic

trends. This suggests that they may reflect bedrock

features. For example, an arcuate low resistivity trend on

sheet B-l, comprising anomalies 20500B to 20470F to 20530D,

correlates with a similarly shaped trend on the total field

magnetic map.

Many of the narrow low resistivity zones correlate with

interpreted bedrock conductors. Some of these, such as the

zone associated with conductors 300300 to 30260E are

coincident with lakes. Conductive lake-bottom sediment may

be influencing the resistivities in these locations.

Surficial features appear to yield resistivities as low

as 50 ohm-m. For example, note the broad resistivity anomaly

- 4-8 -

associated with Middle Shebandowan lake on sheet 3 at line

30410. It does not appear to be possible to differentiate

between bedrock conductors and surficial conductors on the

basis of resistivity alone.

Magnetics

The total field magnetic data have been presented as

contours on the base maps using a contour interval of 10 nT

where gradients permit. The maps show the magnetic

properties of the rock units underlying the survey area.

The total field information has been subjected to a

processing procedure which calculates the vertical gradient.

This enhances near-surface magnetic units and removes the

regional magnetic background. This procedure provides better

definition and resolution of magnetic units, and also

displays weak magnetic features which may not be clearly

evident on the total field maps.

There is ample evidence on the magnetic maps which

suggests that the survey area has been subjected to

deformation and/or alteration. These structural complexities

are evident on the contour maps as variations in magnetic

intensity, irregular patterns, and as offsets or changes in

- 4-9 -

strike direction.

The stratigraphic strike direction as inferred from the

magnetics gently curves from northeast/southwest on sheet B-

1-2 through east/west to northwest/southeast on sheet B-5-2.

Numerous possible structural breaks are apparent. The

predominant orientations of these breaks appear to be

northwest/southeast and northeast/southwest. In area D,

several approximately north/south trending, magnetic, dike-

like features are evident.

Throughout the survey area, many of the magnetic bodies

are long, narrow, possibly stratiform units. Some folding of

these units is evident, particularly in the southern portion

of sheet B-2-2, where a large " S" shaped fold is apparent

between lines 20960 and 21220.

A large oval shaped feature in the northern half of the

survey area on sheet B-l-2, between lines 20460 and 20750,

yields relatively high magnetic responses. This correlates

with a syenite body mapped on the Shebandowan Geological

Compilation map, West Sheet, supplied by Noranda Exploration

Company Ltd. The eastern end of this unit is transected by a

north-northeast/south-southwest trending fault, which appears

to extend from anomaly 20430F to 20910B.

- 4-10 -

r

A long, narrow, strongly magnetic unit is located

coincident with the northern boundary of this oval body. It

also appears to continue westward, and is continuous except

for a few locations where it may be offset by faulting. It

is conductive in several locations, correlating with

conductors 20150C-20220E, 20230F-20340C, 20420B-20470C,

l 20531B-20560B, 20600B-20630B, 20710A-20720B, 20600B-20630B

and 20710A-20720B.

East of the oval magnetic body, between lines 21020 and

21310, is a large circular feature. The magnetics

associated with this unit are less active than that of the

oval feature to the west. This feature correlates with a

granitic body on the geological map.

l A strongly magnetic, lense shaped unit dominates the

t western portion of sheet 4, between lines 40330 and 30570. A

well-defined, north-northwest/south-southeast trending

j structural break is evident near the western end of this unit

on sheet B-3-2. This apparent break appears to extend from

the south end of line 30480 to the north end of line 30450.

The magnetic data in the vicinity of the power line may

! have been affected to a very minor degree. A subtle

herringbone is evident on the calculated vertical gradient,ti

- 4-11 -

which may have resulted from variations in bird height and

bird swing as the helicopter traversed the power line.

If a specific magnetic intensity can be assigned to the

rock type which is believed to host the target

mineralization, it may be possible to select areas of higher

! priority on the basis of the total field magnetic maps. This

is based on the assumption that the magnetite content of the

host rocks will give rise to a limited range of contour

values which will permit differentiation of various

lithological units.

The magnetic results, in conjunction with the other

geophysical parameters, should provide valuable information

which can be used to effectively map the geology and

structure in the survey areas.

VLF

VLF results were obtained from the transmitting stations

at Cutler, Maine (NAA - 24.0), and Annapolis, Maryland (NSS-

21.4). Data from the Annapolis station were presented as

contours of the filtered total field for blocks B and C, and

data from the Cutler station were presented for block D.

Adequate signals were not available during the flying of

- 4-12 -

lines 20380 through 20561 on block B.

The VLF method is quite sensitive to the angle of

coupling between the conductor and the propogated EM field.

Consequently, conductors which strike towards the VLF

station will usually yield a stronger response than

conductors which are nearly orthogonal to it.

Some of the VLF trends parallel magnetic features. These

may reflect conductive material associated with lithological

contacts or faulted contacts. There are some trends which

transect the stratigraphic strike direction as inferred from

the magnetics. These are indicative of conductive material

associated with structural breaks. Other structural breaks

may be inferred where the VLF contours are offset or

truncated.

Some of the possible and discrete bedrock conductors

yield well-defined trends on the VLF. Therefore, the VLF may

be useful as a ground follow-up tool. The filtered VLF will

also show trends due to the edges of flat-lying conductive

sources, such as lacustrine clays.

The VLF contours have been affected by cultural sources.

Power lines and roads in areas C, D and the eastern half of

- 4-13 -

area B yield strong, narrow VLF trends.

The VLF parameter does not normally provide the same

degree of resolution available from the EM data. Closely-

spaced conductors, conductors of short strike length or

conductors which are poorly coupled to the VLF field, may

escape detection with this method. Erratic signals from the

VLF transmitters can also give rise to strong, isolated

anomalies which should be viewed with caution. The filtered

total field VLF contours are presented on the base maps with

a contour interval of one percent.

CONDUCTOR DESCRIPTIONS

It is beyond the scope of this report to provide a

detailed interpretation of all the conductors within the

survey area. The Conductor Description^ section deals with

some of the most interesting geophysical targets that occur

within the survey area. It also mentions some of the

structural and formational conductors which may be important

as an aid for geological mapping. The anomaly lists appended

to this report should be consulted to ensure that no

anomalies attributed to bedrock sources are overlooked. All

bedrock anomalies can be considered potential targets for

further investigation.

magnetics, which occupies the northern third of the

survey area on sheet B-l. The conductors reflect narrow

bedrock sources, most of which appear to dip to the

north. Some appear to be magnetic while others are non

magnetic. Those that are magnetic may reflect

pyrrhotite-rich sources or conductive material associated

with magnetite, while those that are not may reflect

graphite-rich or non-magnetic sulphide-rich sources.

Some of the shorter strike length conductors (one or two

line responses) such as 20280B-20290B may be more

attractive as exploration targets than the longer

structural or formational conductors, except where these

appear to be altered. This conductor also yields

magnetic correlation and appears to be strongly

conductive. Conductor 20090B-20100B is a short, weak,

conductor which loosely correlates with a small limb or

fold of magnetic material.

interpreted as two thin conductors, it is possible that

the response here may reflect a thick source (greater

than 10 m thickness). The high calculated conductances

rich source. The magnetics suggest a structural break or

tight fold in this vicinity. Further investigation of

this source is likely warranted.

surficial conductivity. Isolated bedrock conductors, which

occur off to one side of a flight line, or conductors without

approximate thin-dike geometry may also be interpreted as

questionable (B? or S?). These anomalies will likely warrant

further investigation if they have supporting geological,

geochemical or geophysical information.

BACKGROUND INFORMATION

This section provides background information on

parameters which are available from the survey data. Those

which have not been supplied as survey products may be

generated later from raw data on the digital archive tape.

ELECTROMAGNETICS

DIGHEM electromagnetic responses fall into two general

classes, discrete and broad. The discrete class consists of

sharp, well-defined anomalies from discrete conductors such

as sulfide lenses and steeply dipping sheets of graphite and

sulfides. The broad class consists of wide anomalies from

conductors having a large horizontal surface such as flatly

dipping graphite or sulfide sheets, saline water-saturated

sedimentary formations, conductive overburden and rock, and

geothermal zones. A vertical conductive slab with a width of

200 m would straddle these two classes.

The vertical sheet (half plane) is the most common model

used for the analysis of discrete conductors. All anomalies

plotted on the electromagnetic map are analyzed according to

this model. The following section entitled Discrete

Conductor Analysis describes this model in detail, including

- 5-2 -

the effect of using it on anomalies caused by broad

conductors such as conductive overburden.

The conductive earth (half space) model is suitable for

broad conductors. Resistivity contour maps result from the

use of this model. A later section entitled Resistivity

Mapping describes the method further, including the effect of

using it on anomalies caused by discrete conductors such as

sulfide bodies.

geometric interpretation

The geophysical interpreter attempts to determine the

geometric shape and dip of the conductor. Figure 5-1 shows

typical DIGHEM anomaly shapes which are used to guide the

geometric interpretation.

Discrete conductor analysis

The EM anomalies appearing on the electromagnetic map

are analyzed by computer to give the conductance (i.e.,

conductivity-thickness product) in Siemens (mhos) of a

vertical sheet model. This is done regardless of the

interpreted geometric shape of the conductor. This is not an

unreasonable procedure, because the computed conductance

increases as the electrical quality of the conductor

increases, regardless of its true shape. DIGHEM anomalies

have resistivities as low as 50 ohm-m. In areas where ground

resistivities are below 10 ohm-m, anomalies caused by

weathering variations and similar causes can have any

conductance grade. The anomaly shapes from the multiple

coils often allow such conductors to be recognized, and these

are indicated by the letters S, H, and sometimes E on the

electromagnetic anomaly map (see EM map legend).

For bedrock conductors, the higher anomaly grades

indicate increasingly higher conductances. Examples t

DIGHEM's New Insco copper discovery (Noranda, Canada) yielded

a grade 5 anomaly, as did the neighbouring copper-zinc Magusi

River ore body; Mattabi (copper-zinc, Sturgeon Lake, Canada)

and Whistle (nickel, Sudbury, Canada) gave grade 6; and

DIGHEM's Montcalm nickel-copper discovery (Timmins, Canada)

yielded a grade 7 anomaly. Graphite and sulfides can span

all grades but, in any particular survey area, field work may

show that the different grades indicate different types of

conductors.

Strong conductors (i.e., grades 6 and 7) are charac

teristic of massive sulfides or graphite. Moderate

conductors (grades 4 and 5) typically reflect graphite or

sulfides of a less massive character, while weak bedrock

conductors (grades l to 3) can signify poorly connected

graphite or heavily disseminated sulfides. Grades l and 2

conductors may not respond to ground EM equipment using

frequencies less than 2000 Hz.

The presence of sphalerite or gangue can result in ore

deposits having weak to moderate conductances. As an

example, the three million ton lead-zinc deposit of

Restigouche Mining Corporation near Bathurst, Canada, yielded

a well-defined grade 2 conductor. The 10 percent by volume

of sphalerite occurs as a coating around the fine grained

massive pyrite, thereby inhibiting electrical conduction.

Faults, fractures and shear zones may produce anomalies

which typically have low conductances (e.g., grades l to 3).

Conductive rock formations can yield anomalies of any

conductance grade. The conductive materials in such rock

formations can be salt water, weathered products such as

clays, original depositional clays, and carbonaceous

material.

On the interpreted electromagnetic map, a letter

identifier and an interpretive symbol are plotted beside the

EM grade symbol. The horizontal rows of dots, under the

interpretive symbol, indicate the anomaly amplitude on the

flight record. The vertical column of dots, under the

anomaly letter, gives the estimated depth. In areas where

anomalies are crowded, the letter identifiers, interpretive

- 5-8 -

altimeter, overlying conductive overburden, and the location

and attitude of the conductor relative to the flight line.

Conductor location and attitude can provide an erroneous

depth estimate because the stronger part of the conductor may

be deeper or to one side of the flight line, or because it

has a shallow dip. A heavy tree cover can also produce

errors in depth estimates. This is because the depth

estimate is computed as the distance of bird from conductor,

minus the altimeter reading. The altimeter can lock onto the

top of a dense forest canopy. This situation yields an

erroneously large depth estimate but does not affect the

conductance estimate.

Dip symbols are used to indicate the direction of dip of

conductors. These symbols are used only when the anomaly

shapes are unambiguous, which usually requires a fairly

resistive environment.

A further interpretation is presented on the EM map by

means of the line-to-line correlation of anomalies, which is

based on a comparison of anomaly shapes on adjacent lines.

This provides conductor axes which may define the geological

structure over portions of the survey area. The absence of

conductor axes in an area implies that anomalies could not be

correlated from line to line with reasonable confidence.

- 5-9 -

DIGHEM electromagnetic maps are designed to provide a

correct impression of conductor quality by means of the

conductance grade symbols. The symbols can stand alone with

geology when planning a follow-up program. The actual

conductance values are printed in the attached anomaly list

for those who wish quantitative data. The anomaly ppm and

depth are indicated by inconspicuous dots which should not

distract from the conductor patterns, while being helpful to

those who wish this information. The map provides an

interpretation of conductors in terms of length, strike and

dip, geometric shape, conductance, depth, and thickness. The

accuracy is comparable to an interpretation from a high

quality ground EM survey having the same line spacing.

The attached EM anomaly list provides a tabulation of

anomalies in ppm, conductance, and depth for the vertical

sheet model. The EM anomaly list also shows the conductance

and depth for a thin horizontal sheet (whole plane) model,

but only the vertical sheet parameters appear on the EM map.

The horizontal sheet model is suitable for a flatly dipping

thin bedrock conductor such as a sulfide sheet having a

thickness less than 10 m. The list also shows the

resistivity and depth for a conductive earth (half space)

model, which is suitable for thicker slabs such as thick

conductive overburden. In the EM anomaly list, a depth value

of zero for the conductive earth model, in an area of thick

- 5-10 -

coveri warns that the anomaly may be caused by conductive

overburden.

Since discrete bodies normally are the targets of EH

surveys, local base (or zero) levels are used to compute

local anomaly amplitudes. This contrasts with the use of

true zero levels which are used to compute true EM

amplitudes. Local anomaly amplitudes are shown in the EM

anomaly list and these are used to compute the vertical sheet

parameters of conductance and depth. Not shown in the EM

anomaly list are the true amplitudes which are used to

compute the horizontal sheet and conductive earth parameters.

Questionable Anomalies

DZGHEM maps may contain EM responses which are displayed

as asterisks (*). These responses denote weak anomalies of

indeterminate conductance, which may reflect one of the

followingt a weak conductor near the surface, a strong

conductor at depth (e.g., 100 to 120 m below surface) or to

one side of the flight line, or aerodynamic noise. Those

responses that have the appearance of valid bedrock anomalies

on the flight profiles are indicated by appropriate

interpretive symbols (see EM map legend). The others

probably do not warrant further investigation unless their

locations are of considerable geological interest.

- 5-11 -

The thickness parameter

DIGHEM can provide an indication of the thickness of a

steeply dipping conductor. The amplitude of the coplanar

r anomaly (e.g., CPI channel on the digital profile) increases

relative to the coaxial anomaly (e.g., CXI) as the apparent

J thickness increases, i.e., the thickness in the horizontal

plane. (The thickness is equal to the conductor width if the

i conductor dips at 90 degrees and strikes at right angles to

the flight line.) This report refers to a conductor as ,thj.q

when the thickness is likely to be less than 3 m, and thick

when in excess of 10 m. Thick conductors are indicated on

the EM map by parentheses "( )". For base metal exploration

in steeply dipping geology, thick conductors can be high

priority targets because many massive sulfide ore bodies are

j thick, whereas non-economic bedrock conductors are often

, thin. The system cannot sense the thickness when the strike

* of the conductor is subparallel to the flight line, when the

l conductor has a shallow dip, when the anomaly amplitudes are

small, or when the resistivity of the environment is below

S 100 ohm-m.

Resistivity mapping

Areas of widespread conductivity are commonly

- 5-12 -

encountered during surveys. In such areas, anomalies can be

generated by decreases of only 5 m in survey altitude as well

as by increases in conductivity. The typical flight record

in conductive areas is characterized by inphase and

quadrature channels which are continuously active. Local EN

peaks reflect either increases in conductivity of the earth

or decreases in survey altitude. For such conductive areas,

apparent resistivity profiles and contour maps are necessary

for the correct interpretation of the airborne data. The

advantage of the resistivity parameter is that anomalies

caused by altitude changes are virtually eliminated, so the

resistivity data reflect only those anomalies caused by

conductivity changes. The resistivity analysis also helps

the interpreter to differentiate between conductive trends in

the bedrock and those patterns typical of conductive

overburden. For example, discrete conductors will generally

appear as narrow lows on the contour map and broad conductors

(e.g., overburden) will appear as wide lows.

The resistivity profiles and the resistivity contour

maps present the apparent resistivity using the so-called

pseudo-layer (or buried) half space model defined by Fraser

(1978) 1 . This model consists of a resistive layer overlying

1 Resistivity mapping with an airborne multicoil electromagnetic system: Geophysics, v. 43, p.144-172

- 5-13 -

a conductive half space. The depth channels give the

apparent depth below surface of the conductive material. The

apparent depth is simply the apparent thickness of the

overlying resistive layer. The apparent depth (or thickness)

parameter will be positive when the upper layer is more

resistive than the underlying material, in which case the

apparent depth may be quite close to the true depth.

The apparent depth will be negative when the upper layer

is more conductive than the underlying material, and will be

zero when a homogeneous half space exists. The apparent

depth parameter must be interpreted cautiously because it

will contain any errors which may exist in the measured

altitude of the EM bird (e.g., as caused by a dense tree

cover). The inputs to the resistivity algorithm are the

inphase and qaudrature components of the coplanar coil-pair.

The outputs are the apparent resistivity of the conductive

half space (the source) and the sensor-source distance are

independent of the flying height. The apparent depth,

discussed above, is simply the sensor-source distance minus

the measured altitude or flying height. Consequently, errors

in the measured altitude will affect the apparent depth

parameter but not the apparent resistivity parameter.

The apparent depth parameter is a useful indicator of

simple layering in areas lacking a heavy tree cover. The

- 5-14 -

DIGHEM system has been flown for purposes of permafrost

mapping, where positive apparent depths were used as a

measure of permafrost thickness. However, little

quantitative use has been made of negative apparent depths

because the absolute value of the negative depth is not a

measure of the thickness of the conductive upper layer and,

therefore, is not meaningful physically. Qualitatively, a

negative apparent depth estimate usually shows that the EM

anomaly is caused by conductive overburden. Consequently,

the apparent depth channel can be of significant help in

distinguishing between overburden and bedrock conductors.

The resistivity map often yields more useful information

on conductivity distributions than the EM map. In comparing

the EM and resistivity maps, keep in mind the followingi

(a) The resistivity map portrays the absolute value

of the earth's resistivity, where resistivity -

l/conductivity.

(b) The EM map portrays anomalies in the earth's

resistivity. An anomaly by definition is 'a

change from the norm and so the EM map displays

anomalies, (i) over narrow, conductive bodies

and (ii) over the boundary zone between two wide

formations of differing conductivity.

- 5-15 -

The resistivity map might be likened to a total field

map and the EM map to a horizontal gradient in the direction

of flight2 . Because gradient maps are usually more sensitive

than total field maps, the EM map therefore is to be

preferred in resistive areas. However, in conductive areas,

the absolute character of the resistivity map usually causes

it to be more useful than the EM map.

^Interpretation in conductive environments,

Environments having background resistivities below 30

ohm-m cause all airborne EM systems to yield very large

responses from the conductive ground. This usually prohibits

the recognition of discrete bedrock conductors. However,

DIGHEM data processing techniques produce three parameters

which contribute significantly to the recognition of bedrock

conductors. These are the inphase and quadrature difference

channels (OIFI and DIFQ), and the resistivity and depth

channels (RES and DP) for each coplanar frequency.

The EM difference channels (DIFI and DIFQ) eliminate

most of the responses from conductive ground, leaving

l.

- 5-16 -

responses from bedrock conductors, cultural features (e.g.,

telephone lines, fences, etc.) and edge effects. Edge

effects often occur near the perimeter of broad conductive

zones. This can be a source of geologic noise. While edge

effects yield anomalies on the EH difference channels, they

do not produce resistivity anomalies. Consequently, the

resistivity channel aids in eliminating anomalies due to edge

effects. On the other hand, resistivity anomalies will

coincide with the most highly conductive sections of

conductive ground, and this is another source of geologic

noise. The recognition of a bedrock conductor in a

conductive environment therefore is based on the anomalous

responses of the two difference channels (DIFI and DIFQ) and

the resistivity channels (RES). The most favourable

situation is where anomalies coincide on all channels.

The DP channels, which give the apparent depth to the

conductive material, also help to determine whether a

conductive response arises from surficial material or from a

conductive zone in the bedrock. When these channels ride

above the zero level on the digital profiles (i.e., depth is

negative), it implies that the EH and resistivity profiles

are responding primarily to a conductive upper layer, i.e.,

conductive overburden. If the OP channels are below the

zero level, it indicates that a resistive upper layer exists,

and this usually implies the existence of a bedrock

- 5-17 -

conductor. If the low frequency DP channel is below the zero

level and the high frequency DP is above, this suggests that

a bedrock conductor occurs beneath conductive cover.

The conductance channel CDT identifies discrete

conductors which have been selected by computer for appraisal

by the geophysicist. Some of these automatically selected

anomalies on channel CDT are discarded by the geophysicist.

The automatic selection algorithm is intentionally

oversensitive to assure that no meaningful responses are

missed. The interpreter then classifies the anomalies

according to their source and eliminates those that are not

substantiated by the data, such as those arising from

geologic or aerodynamic noise.

Reduction of geologic noisQ

Geologic noise refers to unwanted geophysical responses.

For purposes of airborne EN surveying/ geologic noise refers

to EN responses caused by conductive overburden and magnetic

permeability. It was mentioned previously that the EN

difference channels (i.e., channel DIFI for inphase and DIFQ

for quadrature) tend to eliminate the response of conductive

overburden. This marked a unique development in airborne EN

technology, as DIGHEM is the only EM system which yields

channels having an exceptionally high degree of immunity to

- 5-18 -

conductive overburden.

Magnetite produces a form of geological noise on the

inphase channels of all EN systems. Rocks containing less

than 11 magnetite can yield negative inphase anomalies caused \ j by magnetic permeability. When magnetite is widely

distributed throughout a survey area, the inphase EM channels

: may continuously rise and fall, reflecting variations in the

magnetite percent-age, flying height, and overburden

thickness. This can lead to difficulties in recognizing

deeply buried bedrock conductors, particularly if conductive

overburden also exists. However, the response of broadly

distributed magnetite generally vanishes on the inphase

difference channel DIFI. This feature can be a significant

aid in the recognition of conductors which occur in rocks

J containing accessory magnetite.

EM magnetite mapping

i The information content of DIGHEM data consists of a

' combination of conductive eddy current responses and magnetic

permeability responses. The secondary field resulting from

conductive eddy current flow is frequency-dependent and

consists of both inphase and quadrature components, which are

l positive in sign. On the other hand, the secondary field

t resulting from magnetic permeability is independent ofJ

- 5-19 -

frequency and consists of only an inphase component which is

negative in sign. When magnetic permeability manifests

itself by decreasing the measured amount of positive inphase,

its presence may be difficult to recognize. However, when it

manifests itself by yielding a negative inphase anomaly

(e.g., in the absence of eddy current flow), its presence is

assured. In this latter case, the negative component can be

used to estimate the percent magnetite content.

A magnetite mapping technique was developed for the

coplanar coil-pair of DIGHEM. The technique yields a channel

(designated FEO) which displays apparent weight percent

magnetite according to a homogeneous half space model. 3 The

method can be complementary to magnetometer mapping in

certain cases. Compared to magnetometry, it is far less

sensitive but is more able to resolve closely spaced

magnetite zones, as well as providing an estimate of the

amount of magnetite in the rock. The method is sensitive to

ly/4% magnetite by weight when the EM sensor is at a height of

30 m above a magnetitic half space. It can individually

resolve steep dipping narrow magnetite-rich bands which are

separated by 60 m. Unlike magnetometry, the EM magnetite

method is unaffected by remanent magnetism or magnetic

latitude.

The EM magnetite mapping technique provides estimates of

magnetite content which are usually correct within a factor

of 2 when the magnetite is fairly uniformly distributed. EM

magnetite maps can be generated when magnetic permeability is

evident as negative inphase responses on the data profiles.

Like magnetometry, the EM magnetite method maps only

bedrock features, provided that the overburden is

characterized by a general lack of magnetite. This contrasts

with resistivity mapping which portrays the combined effect

of bedrock and overburden.

Recognition of, culture

Cultural responses include all EM anomalies caused by

man-made metallic objects. Such anomalies may be caused by

inductive coupling or current gathering. The concern of the

interpreter is to recognize when an EM response is due to

culture. Points of consideration used by the interpreter,

when coaxial and coplanar coil-pairs are operated at a common

frequency, are as follows i

1. Channel CPS monitors 60 Hz radiation. An anomaly on

- 5-21 -

this channel shows that the conductor is radiating

power. Such an indication is normally a guarantee that

the conductor is cultural. However, care must be taken

to ensure that the conductor is not a geologic body

which strikes across a power line, carrying leakage

currents.

2. A flight which crosses a "line" (e.g., fence, telephone

line, etc.) yields a center-peaked coaxial anomaly and

an m-shaped coplanar anomaly.4 when the flight crosses

the cultural line at a high angle of intersection, the

amplitude ratio of coaxial/coplanar response is 4. Such

an EM anomaly can only be caused by a line. The

geologic body which yields anomalies most closely

resembling a line is the vertically dipping thin dike.

Such a body, however, yields an amplitude ratio of 2

rather than 4. Consequently, an in-shaped coplanar

anomaly with a CXI/CPI amplitude ratio of 4 is virtually

a guarantee that the source is a cultural line.

l 3. A flight which crosses a sphere or horizontal disk

1 yields center-peaked coaxial and coplanar anomalies with

i a CXI/CPI amplitude ratio (i.e., coaxial/coplanar) of

1/4. In the absence of geologic bodies of this

See Figure 5-1 presented earlier.

- 5-22 -

geometry, the most likely conductor is a metal roof or

small fenced yard. 5 Anomalies of this type are

virtually certain to be cultural if they occur in an

area of culture.

4. A flight which crosses a horizontal rectangular body or

wide ribbon yields an m-shaped coaxial anomaly and a

center-peaked coplanar anomaly. In the absence of

geologic bodies of this geometry, the most likely

conductor is a large fenced area. 5 Anomalies of this

type are virtually certain to be cultural if they occur

in an area of culture.

5. EM anomalies which coincide with culture, as seen on the

camera film or video display, are usually caused by

culture. However, care is taken with such coincidences

because a geologic conductor could occur beneath a

fence, for example. In this example, the fence would be

expected to yield an m-shaped coplanar anomaly as in

case #2 above. If, instead, a center-peaked coplanar

anomaly occurred, there would be concern that a thick

geologic conductor coincided with the cultural line.

It is a characteristic of EM that geometrically similar anomalies are obtained fromt (1) a planar conductor, and (2) a wire which forms a loop having dimensions identical to the perimeter of the equivalent planar conductor.

- 5-23 -

6. The above description of anomaly shapes is valid when

the culture is not conductively coupled to the

environment. In this case, the anomalies arise from

inductive coupling to the EM transmitter. However, when

the environment is quite conductive (e.g., less than 100

ohm-m at 900 Hz), the cultural conductor may be

conductively coupled to the environment. In this latter

case, the anomaly shapes tend to be governed by current

gathering. Current gathering can completely distort the

anomaly shapes, thereby complicating the identification

of cultural anomalies. In such circumstances, the

interpreter can only rely on the radiation channel CPS

and on the camera film or video records.

MAGNETICS

The existence of a magnetic correlation with an EM

anomaly is indicated directly on the EM map. In some

geological environments, an EM anomaly with magnetic

correlation has a greater likelihood of being produced by

sulfides than one that is non-magnetic. However, sulfide ore

bodies may be non-magnetic (e.g., the Kidd Creek deposit near

Timmins, Canada) as well as magnetic (e.g., the Mattabi

deposit near Sturgeon Lake, Canada).

- 5-24 -

The magnetometer data are digitally recorded in the

aircraft to an accuracy of one nT (i.e., one gamma) for

proton magnetometers, and 0.01 nT for cesium magnetometers.

The digital tape is processed by computer to yield a total

field magnetic contour map. When warranted, the magnetic

data may also be treated mathematically to enhance the

magnetic response of the near-surface geology, and an

enhanced magnetic contour map is then produced. The response

of the enhancement operator in the frequency domain is

illustrated in Figure 5-2. This figure shows that the

passband components of the airborne data are amplified 20

times by the enhancement operator. This means, for example,

that a 100 nT anomaly on the enhanced map reflects a 5 nT

anomaly for the passband components of the airborne data.

The enhanced map, which bears a resemblance to a

downward continuation map, is produced by the digital

bandpass filtering of the total field data. The enhancement

is equivalent to continuing the field downward to a level

(above the source) which is 1720th of the actual sensor-

source distance.

Because the enhanced magnetic map bears a resemblance to

a ground magnetic map, it simplifies the recognition of

trends in the rock strata and the interpretation of

geological structure. It defines the near-surface local

geology while de-emphasizing deep-seated regional features.

It primarily has application when the magnetic rock units are

steeply dipping and the earth's field dips in excess of 60

degrees.

Any of a number of filter operators may be applied to

the magnetic data, to yield vertical derivatives,

continuations, magnetic susceptibility, etc. These may be

displayed in contour, colour or shadow.

VLF

VLF transmitters produce high frequency uniform

electromagnetic fields. However, VLF anomalies are not EM

anomalies in the conventional sense. EM anomalies primarily

reflect eddy currents flowing in conductors which have been

energized inductively by the primary field. In contrast, VLF

anomalies primarily reflect current gathering, which is a

non-inductive phenomenon. The primary field sets up currents

which flow weakly in rock and overburden, and these tend to

collect in low resistivity zones. Such zones may be due to

massive sulfides, shears, river valleys and even

unconformities.

CYCLES X METRE

Fig, 5-3 Frequency response ol VLF operator.

- 5-28 -

The VLF field is horizontal. Because of this, the

method is quite sensitive to the angle of coupling between

the conductor and the transmitted VLF field. Conductors

which strike towards the VLF station will usually yield a

stronger response than conductors which are nearly orthogonal

to it.

The Herz Industries Ltd. Totem VLF-electromagnetometer

measures the total field and vertical quadrature components.

Both of these components are digitally recorded in the

aircraft with a sensitivity of 0.1 percent. The total field

yields peaks over VLF current concentrations whereas the

quadrature component tends to yield crossovers. Both appear

as traces on the profile records. The total field data are

filtered digitally and displayed as contours to facilitate

the recognition of trends in the rock strata and the

interpretation of geologic structure.

The response of the VLF total field filter operator in

the frequency domain (Figure 5-3) is basically similar to

that used to produce the enhanced magnetic map (Figure 5-2).

The two filters are identical along the abscissa but

different along the ordinant. The VLF filter removes long

wavelengths such as those which reflect regional and wave

transmission variations. The filter sharpens short

wavelength responses such as those which reflect local

geological variations.
