INTRODUCTION
A combined airborne magnetic and VLF-EM survey was carried out on a
block of 24 claims located in Clifford Township, in the Larder Lake
Mining Division, Ontario. The claim holder is D. G. Innes and
Associates, Callander, Ontario. The work was carried out by
Terraquest Ltd., 111 Richmond Street West, Toronto during the period
Jan. 7, 1985 to March 29, 1985.
The survey area was covered by a grid of parallel flight lines spaced
100 metres apart and aligned north-south.
The purpose of the survey was to assist in mapping geology and to
explore for shear zones, faults, and other structures potentially
favourable to gold or base metal mineralization.
2. THE PROPERTY

Map References
1. Map 2283, Clifford and Ben Nevis Townships, O.D.M., 1973.
The geology is well mapped at a scale of l" to \ mile on Map No. 2283.
Most of the property is underlain by felsic and intermediate
volcanics, with more recent intrusions of gabbro to the northeast of
Keith Lake and felspar porphyry lying south and west of Keith Lake. A
diabase dyke striking approximately north 30 0 west cuts through the
south west corner of the property.
There are a number of mineral showings in the vicinity. Galena and
sphalerite have been found in another gabbro intrusion approximately
2 km to the southeast. Gold, silver and base metals were found in
another occurrence of the gabbro some 8 km to the east on the property
of Canagau Mines Ltd. A number of other minor showing are shown on
the geology map mostly south of the property.

4. SURVEY SPECIFICATIONS
4.1 Instruments
The present survey was carried out using airborne instruments
with the sensor elements mounted in the wing tips of a Cessna 182
aircraft, registration C-FAKK. The magnetic field was measured with a
proton precession magnetometer model GSM-8BA, manufactured by GEM
Systems, Toronto. The VLF-EM field was measured with a three
component total field strength instrument, model TOTEM-2A,
manufactured by Herz Industries Ltd., Toronto. Terrain clearance is
measured by a King KRA-10A Radar Altimeter. Data from these three
instruments are processed by a UDAS-100 data processor, manufactured
by Urtec Ltd, and then recorded onto a ninetrack tape recorder, and
printed as profiles on a thermal printer in real time on the aircraft
(Fig. 3). A Geocam video tape system is used to follow the
flight path, and fiducial numbers generated by the UDAS-100 are
recorded onto the video images.
Full specifications of the instruments are given in Appendix A.

4 .4 Photo mosaics
For navigating the aircraft and recovering the flight path, photo
mosaics were made at final map scale from existing air photos. In
order to provide a semi-controlled base the airphotos were laid
down on a topographic map which had been photographically adjusted
to match the photo scale. The laydown was then photographed and
printed at 1:10,000 scale for navigating and flight path recovery.
5. DATA PROCESSING
Flight path recovery was carried out in the field using a video tape
viewer to observe the flight path as recorded by the Geocam video
camera system. The flight path recovery was completed daily to enable
reflights to be selected where needed for the following day.
The remaining data processing was carried out in the offices of
Dataplotting Services Inc. in Toronto.
Magnetic levelling was computed in the standard manner by tying survey
lines to the tie lines. The VLF-EM data was corrected -by applying the
following formula:
- 6 -
(A) Total Field Strength
V = SM + 100 where K - S(A - 2R) + 100 K 100
V s final corrected value in %
M = raw data value from the magnetic tape
S = scale factor
A = average of all M on a given line.
R s standard deviation of A
(B) Quadrature
Q = SN where K * SB * 100 K 100
N s raw data
B s average of all N
The vertical magnetic gradient is computed from the total field
data using a widely accepted method of transforming the data set
into the frequency domain, applying a transfer function to
calculate the gradient, and then transforming back to the spatial
domain. The method is described by a number of authors including
Grant, 1972, and Spector, 1968.
Grant, F. S., Review of data'processing and interpretation methods
in gravity and magnetics, Geophysics, August 1972.
Spector, A., 1968, Spectral analysis of aeromagnetic maps: unpub.
University of Toronto thesis.
- 7 -
These calculations, and all other corrections and map contouring were
carried out by Dataplotting Services Inc. of Toronto.
6. INTERPRETATION
The magnetic pattern both on the total field and the calculated
vertical gradient is relatively quiet, the maximum relief being about
150 gammas. Considerable information about the underlying geology is
available however. The existing geology was related to the magnetic
patterns to see if they could be used to identify geological units.
Some of the units showed a reasonable correlation and an attempt was
made to modify the geology map.
The diabase dyke is clearly seen as a magnetic high cutting through
the southwest corner of the property. Unit number 4, the gabbro,
shows an unexpectly quiet magnetic pattern. Unit number 3, the felsic
volcanics is also quiet as would be expected. Unit number 2, the
intermediate volcanics appears to have a weak magnetic response, also
as would be expected. The contacts between these units have been
redrawn on this basis.
A number of VLF conductor axes were found on the property, mostly
trending in a south to southeast direction. Some of these are related
to the two lakes that lie on the property but in general this is a
rather unexpected direction considering the strike of the regional
geology. Conductor A lying on the east side of the grid and crossing
through the gabbro does not appear to be related to overburden and may
be of interest as an indicator of conductive minerals within bedrock.

7. SUMMARY
A combined magnetic and VLF EM survey has been done on the claim
group at a line density of approximately 1.6 km per mineral claim.
The data has been used to modify and update the existing geology. At
least one VLF conductor is considered of interest for additional
prospecting.

Specifications
Introduction.The Totem-2A measures basically the same parameters and shares the same package configuration as the well establish ed Totem-1 A.
This new generation instrument, however, measures multiple parameters on two channels simultaneously, with less noise and greater accuracy. These advancements have been achieved while maintaining the simple installation and operat ing procedures of the 1A model.
The Totem-2A employs state of art digital and linear integrat ed circuits to implement the functions of crystal controlled phase locked loop frequency synthesizers, dual frequency heterodyne conversion and proprietary time domain sampl ing vector computation techniques.
Features.The principal parameters measured are the change in total field and the vertical quadrature field. Parameters also available are the total field gradient (from sensors in two locations) and the horizontal quadrature field. The quadrature polarity is defined by the direction of flight relative to the field. The total and quadrature magnitudes are insensitive to sensor orientation in pitch, roll and yaw.
One obvious advantage of dual frequency operation is that primary sources can be selected to ensure good coupling with conductors of any orientation. Potential uses of the gradient mode are enhanced interline contouring and deliniation of multiple conductors with horizontal and vertical gradient respectively.

GeotechGeotech Datacam Video Flight Recorder System
The Geotech Datacam System provides an innovative method of recording the flight path together with data from the user's acquisition equipment on video cassette tape in stead of the usual 35 mm film. The system consists of a data interface, video camera and a video cassette recorder. All data and video are available for review immediately after each flight since no processing is required. The B&W video camera is fitted with a super wide angle tens and automatic iris for accurate exposure control, even under low light condi tions, with no operator adjustment. Usable video can be ob tained with only 0.1 foot candles of light.
The video cassette recorder is designed for easy loading and can store data such as real time, day and date, fiducial numbers, values of magnetometer, VLF and other information on the top portion of each frame. All data and video images are available for immediate review after each flight without processing. Each cassette provides two hours of recording time when run at normal speed. Longer recording times are available with some sacrifice in resolution. Interfacing Datacam to the data acquisition system of the user will be re quired.

The Universal Data Acquisition System, or UDAS, is the most advanced and versatile programable data acquisition system available for ground and airborne geophysical survey applications. This small, lightweight system will accept data in virtually any format — analog or digital, serial or parallel — from any number of simultaneous sensors and sources.
The UDAS combines both digital and analog recording functions into a single compact lightweight console. All recorded data can be simultaneously registered on any 9-track magnetic tape unit as well as being recorded in analog form on an internal printer/recorder. The printer/recorder operates under software control, it can register up to 16 separate traces with total flexibility as to channel width and position.
The UDAS can be supplied as a combined digital/analog recording system or as a fully integrated geophysical survey system. With the addition of an interface and control console the UDAS is programed to handle a dual (upward/downward) full spectrum gamma ray spectrometer capable of accommodating
up to 14 crystal detectors in a coincidence or anti coincidence mode. It also includes a proton magnetometer featuring automatic tuning with 0.1 gamma sensitivity. The system can also be programed to process the signal or frequency from cesium and fluxgate magnetometers.
All functions are controlled via a hand held terminal with keyboard and a 24 alphanumeric character display. The terminal can be fixed to the console or operated in a remote position.
The system inputs and outputs include a 24 character alphanumeric display, 2 RS232 input/output ports, 16 input analog channels, 30 separate input/output ports and 56 input/output lines for BCD and binary data, 3 accumulator inputs for frequency and pulse counting and a CRIB - IEEE-488 high speed data BUS. Optional features include an interface to dual floppy disk converting the basic UDAS to a software development or data processing system.
The system can be interfaced to any number of recording devices such as magnetic tape drive, external chart recorder, cartridge tape drive, CRT display and plotter/printer.
In addition to its main function as a lightweight, compact data acquisition system for airborne geophysics, the versatility of the UDAS hardware and software makes it suitable for a variety of additional applications such as marine geophysics, truckborne geophysics, field editing tape copy and processing, base station monitoring, borehole logging, environment and industrial monitoring as well as a stand alone software development system.
