1. INTRODUCTION
This report details the logistics and interpretation
I ! of a fixed-wing airborne magnetic/VLF-EM/radiometric survey flown
FT for Noratida Exploration Company, Ltd.
The survey was commissioned by Mr. Garth Pierce of Noranda
i' Exploration Company, Ltd. T.J. McConnell, Geophysicist for
Questor, supervised the data compilation and interpretation through['li to the completion of the project in October, 1987.
: The survey area consists of two blocks, comprising 1383
kilometres of traverse and control lines. These were flown between
| the dates of July 24 and July 26, 1987.
The project is located in the Straw Lake area, Ontario.
N.T.S. Map Sheets 52F/4 and 52F/3 include the survey sites (see

2d. Survey _Propedu re
During the survey, the aircraft maintained a terrain
(-: clearaiice as close to 91 metres as possible. In areas of sub
stantial topographic relief or large population, the aircraft
r height may exceed 91 metres for safety reasons. The aircraft's air. j
speed was maintained at approximately 110 knots while on survey.
i-i .] The details of each production flight are documented on the
r> flight logs by the equipment technician. The logs include the
'' survey times, line numbers and fiducial intervals, as well as a
j.i record of inflight calibrations, equipment irregularities and
atmospheric conditions. One may refer to these logs in order to
relate the flight path film to the geophysical data.
,. During the course of the survey the following data were
' recorded:
f 1. airborne magnetometer data;
2. secondary VLF signals (both total field and quadrature
* components) from two stations:
- Cutler, Maine (NAA - 24.0 kHz)
'•'- - Seattle, Washington (NLK - 24.8 kHz)
' 3. the count rates from four energy windows of the gamma radiationt '
spectrum. These windows relate to:
- Potasium K40*.**
- Uranium Bi 214
- Thorion Tl 208
,' - Total Count
4. a record of the terrain clearance as provided by radar
s altimeter;i ..

5. a photographic record of the terrain passing below the aircraft
as obtained from a 35 mm. camera;
i < 6 . time markers impressed synchronously on the photographic and
geophysical records to facilitate accurate positioning on
[1 photomosaics;
7. ground base station magnetometer data.
Bi, 2e. Magnetic Diurnal
' Diurnal variations in the earth's magnetic field were
I; recorded to an accuracy of + 1 nT using a base station equipped
with a Geometries G-826 Proton Precession Magnetometer. It was
monitored periodically during the day for severe diurnal changes
(magnetic storms). A variation of 20 nT over a 5 minute time
* period was considered to be a magnetic storm. During such an
| ; event, the survey would normally have been discontinued or
postponed and any survey data would have been scrubbed.
j- The base station magnetometer was set up in a magnetically
quiet area near the crew quarters in Fort Frances.
! 2f. Data Recovery j
The flight path of the aircraft was recorded by a stript'jj camera on black and white, 125ASA, 35mm. film which was exposed
continuously while on line. The aperture setting on the camera
L; can be manually adjusted by the operator during flight, assuring
[' the proper exposure of the film. The camera .was fitted with at ( *
wide angle 18 mm. lens. Fiducial numbers were imprinted on theri
film, marked onto the analogue records and recorded digitally atI j * -6-
1. 1
the same itistaiit.
The navigation references were flight strips at a scale of
( 1:20,000 which were made from the base maps. The equipment
' operator enters the flight details information into the digital
P data system where they were recorded and verified
(read-after-write). The information includes line number, time,
j fiducial range and other pertinent flight information. This
... information was compared to the film, analogue records and the
!-: magnetic base station recording at the completion of the survey
\\ f light.
The film and all records were developed, edited and | I checked at the completion of each flight. All analogue records
were inspected for coherence with specifications. Recovery of
'' the flight track was then carried out by comparing the negative
I' of the 35mm. film to the topographic features of the base map." * . , • _
These procedures were performed on the survey site daily
r by the data technician so that the data quality and progress
could be measured objectively. Reflights for covering
I; navigational gaps and other deficiencies were usually flown on
\' the following day.

3b< Flight Path
The flight path recovery was done onto topographic base
? maps at the base of survey operations and then shipped back to
the main office where it was transferred to photomosaic base
!'i ; maps. Any long gaps in recovery were filled in on the '•i
photomosaic. An attempt was made to pick points at an averageP|] interval of one kilometre. This corresponds to approximately one
i r whole fiducial unit or 20 seconds. The picked points do not
necessarily fall on whole fiducial numbers.
H The flight path recovery was accurately digitized on a
flat-bed digitizer using the picked point coordinates. Ther recovery was then routinely verified by a computer programme
. . 'speed check 1 , which flags any abnormalities in the distance per
'' fiducial unit between picked points on a traverse line. As a
! filial check, the rough magnetic contour maps were examined for
contour irregularities that could be attributed to recoveryr »
: errors.
? i \ •
3c. Mag i ie tics
A Geometries 826 Proton Precession Magnetometer was
'- operated at the survey base to record diurnal variations of the
earth's magnetic field. The clock of the base station was
r. synchronized with that of the airborne system to permit removal
of diurnal drift. Any subsequent leveling changes were made
[' ; utilizing control line crossing differences.
I.- The corrected data were interpolated onto a regular grid
using a cubic spline technique. The resulting grid provides the
| basis for presenting the magnetic contours. The total field
magnetic data were presented as contours on a 1:20,000
I photomosaic base map. Where gradients permit, a contour interval
[_., of 5 nT was used.
' Calculated vertical magnetic gradient maps were also
|" produced for the four survey blocks. The mathmetical operator
used is designed to extract and display weak magnetic signatures
| which are not readily apparent on the total field magnetic map.
f For interpretation purposes the vertical gradient map is usually
' very useful, since it improves the recognition of near-surface
M magnetic bodies.

3d. VLF/EM
The VLF maps of the two areas record the total field and
i.-:1 quadrature components of the secondary VLF signals from the
station at Cutler, Maine (NAA - 24.0 kHz). These results havenI been plotted as filtered total field contours and as quadrature Li
profiles.
Pli The VLF method is sensitive to the angle of coupling
i- between the conductor and the propagated EM field. As such,
conductors which strike towards the VLF station will usually
I. yield a stronger response than conductors which are nearly
orthogonal to it. VLF/EM anomalies are not EM anomalies in the
j conventional sense. EM anomalies normally reflect the eddy
j ; currents induced in a conductive body by the primary field.
VLF/EM anomalies, however, reflect the effects of current
I. gathering, which is a non-inductive phenomenon. The primary
field from the transmitting station sets up weak currents which
! flow in the bedrock and overburden. These currents tend to
gather in low resistivity zones such as may be due to massive
li sulphides, faults, shears, river valleys or zones of conductive
1 ] overburden. j
The total field yields peaks over VLF/EM current
[j concentrations, while the quadrature component yields crossovers.
., VLF anomalies which appear to transect the magnetic data, and
*f those VLF trends which appear to be truncated or offset, are
' often due to fault or shear zones.
-11-I
3e. Ra d }pme t r i cs
The four channels of radiometric data collected over the
!; survey area reflect the count rates from 'windows' on the gamma1 '
radiation spectrum in the vicinity of the photopeaks of interest.l'i[.'! The gamma radiation spectrum of the complex uranium andti
thorium decay series contains numerous photopeaks over the range
[.: f rom a few KeV to 2.8 MeV. The key photopeaks for separating the
»' uranium and thorium contributions are 1.76 MeV (representing
Bismuth-214) for uranium and 2.62 MeV {representing Thallium-208)
L for thorium. The other photopeaks in the decay series of uranium
and thorium are either of too low energy (and thus strongly
i attenuated in air) or they cannot be readily resolved by the
r detectors either from one another or from the Compton scatter j >
background.
j' Potassium (K^-40) possesses a single photopeak at 1.46 MeV
atid is a major constituent of most rocks. The relative potassium
content of most rocks falls between 0.1% and 10%. Neither
, u ranium or thorium are major constituents of common rocks. The
*' uranium content ranges between 0,4 PPM and 4.0 PPM while that of
H thorium is about 4 times greater than uranium. The total and t--,
relative amounts of each radio element varies for different types
Vy of rock formations and as such can be used as an aid to
fi geological mapping.

4. SURVEY RESULTS
4a. Geo 1 pg i ca 1 Pe r spec t i ve
The geology map available to the author was of 1939
vintage and therefore only a general description of the area will
be given. More recent geology maps should be consulted for an
up-to-date geological perspective.
In general, the area is underlain by rocks of Archean age.
Block A is noted to have occurences of sedimentary rock and small
bands of iron formation hosted within the schistose volcanic rock
which underlies most of the block. A NNE striking stringer of
horneblende, gabbro, diorite or some related rock type is found
intruding into the block in the southeast corner. A small area
of granitic rock is suggested in the SW central section of Block
A.
Block B has basically the same geological formations
present within its boundaries with the exception that no iron
formations or gabbro, diorite, etc. intrusions have been noted
within the area.

BLOCK A
1.; The total field magnetic contours in this area delineate
two rock types with distinctly different magnetic signatures. The
[] northwest central section of the block is very quiet magnetically
while the rest of the block displays an active magnetic field[1\\ consisting of numerous short strike length, curvilinear magnetic
trends. The stronger of these features are highlighted on the
vertical magnetic gradient map.
' The NNE striking stringer of horneblende, gabbro, diorite
or related rock type coincides with a slightly arcuate magnetic
lineatioii on the southwest end of line 10600. These magnetic
.- contours correlate with the topographic contour outline of a thin
*' strip of land among a series of lakes. This correlation of
[' magnetic contours to topographic features is repeated in many
locations within the survey area suggesting that the topography
' may be controlled by bedrock structure.
fi The VLF response lineations generally trend east-west for
» the inline channel. This is to be expected since Cutler, Maine
J 1 is almost due east of the survey area. Some linear features
striking in different directions are apparent as offsets andP| ( truncations of the VLF responses.
,. As was expected, the K-40 and total field radiometric
' J contour maps guite accurately map the water covered portions of
| ' the survey block as areas of low radiation count. Over the dry
land sections, the radiometric contours agree quite welli \I with the magnetics. This could be partly due to the apparenti j
-14-
correlation between the magnetics and the topography withi
the topography having a geometric influence on radiation
t intensity. However, some correlation has been noted between the
higher radiation counts and the magnetically active areas in
J'.j the survey block.

.BLOCK. B
The VLF trends within Block B seem to closely follow the
ji channels of low topographic relief. This would suggest that
these lower elevation swampy areas have conductive sedimentT i
I/. associated thereby creating low resistivity channels for the VLF
current flow. Numerous lakes in the area show the same
I ; correlation indicating the presence of conductive bottom
r/; sediments. As in Block A, the dominant strike direction is
east-west reflecting the orientation of the station at Cutler,
Maine with respect to the survey area. However, lineations in
other directions can be seen. A NE-SW striking trend, defined by
| offsets and truncations of the lineations striking east-west, can
, be observed crossing the following two points:
' - Iiitersection of lines 29020 and 20230
I" - Iiitersection of lines 29010 and 20411
This feature is also readily observed on the total field magnetic
\. map as a wide lineation with a quiet magnetic signature.
,. Other magnetic field lineations are also observed tovi
i correlate with VLF trends. Manitou Stretch, a long narrow body
I" of water starting at line 20820, Fid 3875 and flowing east thenI
northeast out of the area and up to Lower Manitou Lake, seems torj- be structurally controlled. Lineations in both the magnetics and
,, the VLF support this suggestion.*
i; Several areas of both quiet and active magnetic fields are
J' observed within the boundaries of Block B. A careful study ofi '•
the correlation of magnetic susceptibility to rock type would r * i help to yield better located geological boundaries.
-16-
li\ ; i i
Mapping of different bedrock structures may also be
possible using the radiometric maps. As with Block A» the K-40
and Total Count contours closely follow the magnetic contours.
The southern section of the lineation mentioned earlier as
striking diagonally across the intersection of lines 29020 and
20230 stands out strongly as an elongated ridge of high radiation
count. Careful study of all the parameters should yield many
other interesting correlations.
-17-
5. CONCLUSIONS
In both Blocks A and B, close correlation has been noted
r among the VLF, magnetic and radiometric data sets. The contour
maps produced from this data show a very close relationship to
r> the topography of the areas suggesting that the topography is
structurally controlled by bedrock features.
1] During the interpretation process, the author made use of
f color contours of the radiometric data. Using a light table,
these maps were overlain with the total field magnetics and a
I photomosaic base map. The resulting visual display was extremely
useful for relating the three information sets to one other. Ar [. rough color contour map of the PotasiurorThorium ratio was also
t, found to be very informative. These very useful additional maps
can be obtained from Questor at any time,

APPENDIX B;. VLF-EM Receiver! , • •-——• • '——————
HER2 INDUSTRIES LTD. TOTEM 2A
The Totem 2A VLF electromagnetic airborne receiver
I; measures the total field and vertical quadrature components of
the magnetic field radiated from VLF radio transmitters (one orn[•j two stations can be recorded simultaneously). The output of the
p receiver is +_ 1.0 volt for a change in field strength of + 100%.
'' These components are digitally recorded with a sensitivity
[ of 0.1%. The frequency range of the receiver is from 15 kHz to •', '
25 kHz, selectable in 100 Hz steps. A built-in spherics filterr[ reduces the noise contribution of impulse type interference.
., General noise levels depend on the availability of a suitable
' ' station of reasonable signal strength. Ambient noise exceeds the
{* internal noise of the system and generally is in the neighbour
hood of II or better'when in the presence of a strong station. ;
[' The total field tends to yield peaks in field strength
., over VLF current concentrations of the selected frequency. The
4: quadrature component tends to yield crossovers. The quadrature
[' polarity is defined by the direction of flight, relative to the
field.nIt One obvious advantage of dual frequency operation is that
primary transmitter sources can be selected to ensure good
i j coupling with conductors in any orientation. Stations are

which is parallel to the flight lines (inLINE station), and one
field which is orthogonal to the flight line direction (ORTHO
station). Using this convention, it is found that the LINE
channel response best delineates conductors which strike 90° to
the line direction, and the ORTHO channel response best
delineates conductors which parallel the line direction.
This can be simply summed up by noting that conductors
which strike towards a VLF station will usually yield a stronger
response than conductors which are nearly orthogonal to it.
The sensor itself is housed in the .tail boom of the
aircraft. The filter operator used for processing the data is as

APPENDIX D;. Calibration Procedures
[1Calibration of survey equipment was usually performed at
[ the beginning and end of each survey flight.
The continuous chart speed of the RMS Analogue Recorder
H was set at 15 cm./minute.
r." The macjnetomet£r data are recorded on two scales: a fine
and a coarse scale. The two scales are permanently set so that a
[;, full scale deflection of 100 nanoTeslas is equivalent to 10 cm.
on the fine scale and a shift of 2 cm. indicates a 1000 nanoTesla
j , change on the coarse scale.
£• The aircraft jradar; ^It^iniejter; is calibrated so that anp altitude of 91 metres is positioned on the line 13 cm. from the• •»
r bottom of the analogue record. This was the nominal flying
height of the survey, wherever relief and aircraft performance
| are not limiting factors. One cm. above the 91 metre level
P corresponds to an altitude of 60 metres and one cm. below
*' correlates with 122 m. in altitude.
p The VLF-jDM receiver output is manually calibrated during
the ferry flight to the survey area. At altitude and out of n [j ground effect, the receiver response reflects only the primary
(• field strength. Using potentiometers, the output voltage for
each channel is set to 1.0 volts. Any subsequent variation in
f' field strength due to secondary sources is presented as a
percentage of the primary field. An output change of 100 mV!'|j would therefore represent a 10% variation in field strength.
Ii
Spectrometer tests and calibrations are performed on a
regular basis and are recorded in both analog and digital form.
These tests, which are clearly annotated on the operators flight
log, are as follows:

Because of the relatively large distance between the
crystals and the operators seat, the radioactive samples were
stored in the aircraft. A lead box was used to store the samples
during the survey flying. This made it possible to do the
stripping tests in the air during the ferry flight to the survey
area.
The atmospheric test was done typically at 3000 feet above
ground level.
A test line was chosen to the south of the survey area.
The location of this line is shown in Figure D-l. The line
starts out over land, continues over a large lake and over two
[j
t;
islands in the lake, theii continues over land once again. The
islands provided a reliable navigation fix for a repeatable
source of radiometric data. This made it possible for the
operator to accurately verify system integrity and the degree of
rainfall suppression, if any.
The same test line was used for the absorption coefficient
calibration. The test line was flown four times at altitudes of
300, 400, 500 and 600 feet.
