INTRODUCTION
PURPOSE OF SURVEY
A VLF-EM survey was carried out on the Tisdale No. 5 group of
claims, Tisdale Township, to assist in defining the bedrock stratigraphy
in the area and to possibly outline potentially gold-bearing bedrock
structures.
LOCATION AND ACCESS
The Tisdale No. 5 claim group is located in the Tisdale Township,
Porcupine Mining Division, and is centered approximately 5 kilometers
northeast of the City of Timmins, northern Ontario. The Tisdale Townshipt o t
is centered at approximately 48 30 N and 81 16.5 W and is indexed under
N.T.S. 42-A/6, 11.
The Tisdale No. 5 claim group is accessible year-round by means of
La Forest Road (base line road) which runs from Hwy. 545 to the
Tiramins airport road.
Regularly scheduled air service is provided by Air Canada to Timmins
Ontario.

GEOLOGY
TISDALE CLAIM GROUP NO. 5
The most recent mapping and compilation of Tisdale Township has
been carried out by Ferguson, 1968 (Geological Report 58 and Map 2075).
Based on this work there is no exposure on this group although it appears
to be underlain by metasediments.

INTERPRETATIONt
VLF - EM SURVEY
Details concerning equipment, survey procedures and data presentation
are contained in Appendix I to this report. The reader is referred to the
In-phase and Quadrature proifle plots presented on the map for the Tisdale
No. 5 claim group.
i*
The profiles show a number of anomalies, many of which are considered
to be due to culture, i.e., conductive overburden, geological noise,
spurious sources. The general strike direction of these anomalies appears
to be ENE. Two, or possibly three, of the observed anomalies warrant a
more detailed explanation:
Line 16+00 W, Stn. 4+00 S to Line 20+00 W, Stn. 2+25 S
(Clain No. P. 595759).
These are fairly typical profiles, showing a positive in-phase
crossover and a negative quadrature inflection anomaly. The amplitude
response suggests a moderately conductive source. The observed, broad
in-phase anomaly on Lines 17W - 19W suggests, however, that the
conductor is probably due to overburden.
Line 13+00 W, Stn. 4+25 N to Line 17+00 W, Stn. 3+75 N
(Claim No. P. 595756), AAgain we observe a positive in-phase crossover
together with a negative quadrature inflection on several of the survey
lines. The broad in-phase anomaly on Lines 14+00 W - 15+00 W suggest,
however, that this anomaly is due to a moderately conductive overburden
layer.
INTERPRETATION (CONI*D)
- Line 18-K)0 W, Stn. 7+75 N to Line 19 + 00 W,
Stn. 7+50N (Clain No. P595762).
The exact location and strike extent of this conductor
is not known as it occurs on the north edge of the Survey
area and the shape of the in-phase and quadrature profiles
is not fully defined. The positive in-phase crossover
together with a weak, negative quadrature inflection suggest?
a moderately conductive source.
i*
Further work is recommended on the Tisdale No, 5 claim group with the
horizontal loop EM method to test those VLF - EM conductors outlined by the
present survey. There is no bedrock outcrop in the area and the depth of
overburden cover is not known. Two, or possibly, three, of the VLF-EM
anomalies may be due to bedrock sources.
Detailed magnetometer surveying should be carried out at the same
time to assist in interpreting the geological structure in the area.

APPENDIX NO. l
VLF-EM METHOD
A. GENERAL PRINCIPLES
The VLF (Very Low Frequency) EM method employs an artificial source of EM waves - a VLF antenna, several hundred feet high, which acts essentially as a vertically grounded wire. A worldwide network of high-power VLF stations established for marine and air navigation act as the sources for the VLF-EM exploration method. At present, suitable transmitters for EM prospecting in North America ace located at Cutler, Maine; Annapolis, Md. and Seattle, Washington. The transmitted frequencies (in the 20 KHz band) are very low frequency (VLF) only by comparison to broadcasting standards, but are in fact very high relative to any other geophysical EM system.
The VLF antenna current is vertical. The main magnetic field component of the primary (transmitted) signal is horizontal and theoretically tangent to circles about the antenna mast. Hence, a transmitting station should be chosen so that its direction is almost parallel to the geological strike in the survey area so as to produce a magnetic field perpendicular to the strike. If a conductor is located in the survey area, eddy currents are established producing a secondary field in the vicinity of the conductor. The VLF-EM-16 equipment measures the vertical components of this secondary field.
The fact that the source is at infinity means the primary field is essentially uniform over the survey area and hence all conductors are energized uniformly. This enables the detection of a broad variety of conductors, ranging from good conductors - graphite, massive sulphides, to poor conductors - muskeg, clay edges, shear zones, contacts ...At times this may be a disadvantage, however, since it may emphasize large-scale, relatively poor conductors at the expense of smaller concentrated bodies. In many environments, the anomalies of interest can be masked by the large amount of geological noise. The penetration of the system is limited by its high frequency in the presence of conductive overburden. However, if the subsurface is resistive, for example, little overburden^ the penetration can be quite deep due to the transmitter being so far removed.
The VLF-EM method is also affected by topographic effects; spurious anomalies being picked up on top of conductive hills because the resultant field tends to follow the slope. The distinction between anomaly conductivity and depth is also often difficult. Another major drawback is that it is not always possible to use a transmitting station which gives a primary horizontal field striking at right angles to the . ~ geologic strikes in the survey area. In this case, two VLF transmitters, at approx. right angles to each other, should be used to provide better coverage.
m
APPENDIX NQ. l PAGE TWO
B. EQUIPMENT
The Geonics EM-16 measures the tilt angle and quadrature components of the resultant (secondary) EM field. The instrument consists of two coils or antennas with axes perpendicular to each other and linked to appropriate electronics.
C. SURVEY PROCEDURE
Readings were taken at 25 meter intervals along lines generally spaced 100 meters apart.using Cutler, Maine as the transmitting station.
The survey technique is listed below:
1. The most probably strike of interest is decided and thetransmitter station more closely along strike, with a detectable signal, is chosen.
2. The proper receiver channel is selected to receive the transmitted signal. This may involve plugging in a circuit module.
3. Direction to transmitter station is determined by rotating the axis of the longer receiver coil in a horizontal plane. The transmitter is located in the direction of minimum field -strength, - i.e., minimum noise from the speaker. With this orientation the axis of the long coil should be pointing more or less in the direction of the transmitter station.
4. Receiver is then oriented with the long coil vertical ancj axis of the small coil at the bottom, the reference coil, oriented perpendicular to the transmitter direction.
5. Tilt angle response is measured by rotating the instrument about a horizontal line which points toward the transmitter, until minimum noise is heard.
6. Quadrature response is measured by rotating the small dial until the best minimum is heard.
7. Facing direction and local terrain is recorded together with the. tilt angle and out of phase measurements.
A complete specification for a V.L.F. reading includes:
1. tilt angle response2. quadrature response3. facing direction4. line azimuth5. transmitter and frequency6. terrain
APPENDIX NO. l PAGE THREE
C. . SURVEY PROCEDURE (CONT'D)
The direction the operator is facing during measurement is very important with the Geonics EM 16 instrument because tilt angles above horizontal are positive and those below are negative. Other conventions exist for recording the tilt angle but only the facing convention is discussed here.
The tilt angle and quadrature responses for the survey reported herein have been plotted at a horizontal scale of 1:2500 and a vertical scale of l cm - 10Z. All readings were taken facing north along the survey line.
