INTRODUCTION ' -

Magnetometer and VLFelectromagnetic surveys were completed over

part of Tower Gold Resources Ltd, 'Commodore' claim group in

Lebel Township. The claims lie to the west of and apparently

along strike from the Upper Canada Gold Mines property that

produced 4.7 million tons grading 0.30 opt gold. This report

presents the results of the geophysical surveys.

PROPERTY, LOCATION, ACCESS

The portion of the 'Commodore' property covered in this report

consists of 3 contiguous mining claims numbered L,495894, L,

550832 and L.550833. The claims are held by 262654 Investments

Ltd., 268 Lakeshore Road East, Mississauga, Ontario.

The claims are located in east-central Lebel Township, Larder

Lake Mining Division (NTS: 32D 4W), about 6 miles east of the

Town of Kirkland Lake. Highway # 66 cuts through claim L.550833.

A property and location map is provided overleaf, Figure 1.

claims have been previously staked and prospected as evidenced

by the numerous old claim posts, pits, and trenches seen during

the surveys. Assessment work recorded on the claims ( OGS -Assess

ment Files, Office of the Resident Geologist, Kirkland Lake,

Ontario) includes:

- 1950 - Kirkland Commodore Mines drilled if holes on L, 495894 and 2 holes on L. 550832 after geological mapping.

- 1970 - G. S. Mayhew trenched on L. 550833.

- 1971 - T. Gudrie trenched on all 3 claims.

- 1977 - Canico completed geological and magnetometer surveys over L. 550832 and 33.

- 1980 - Queenston Gold Mines staked the claims but no work was recorded.(L. 550832 and 33).

EXPLORATION PROGRAM

Gridding

A grid of picket lines totalling 2.4 miles and .53 miles of

baseline was cut over the claims during the Fall of 1981 and

the Spring of 1982. The baseline strikes east-west and perpen

dicular crosslines are cut every 400 ft along the baseline.

Pickets were chained and set every 100 feet along all the cut

lines.

A perminent base station was established for geophysical tie-in

purposes at 0+00, 52E, just west of the Esker Park road. All

claim posts were tied to the grid and are shown on Fig. 2 b 3.

YLF-EM Survey

A VLF-EM survey was performed on May 27 - 28, 1982 over the claims

to test for possible faults and / or conductive horizons, and to

- 3 -

help the geological interpretation. A Geonics Ltd. 'EM-16'

VLF-EM receiver was used and readings were taken every 100 ft

along the grid lines for a total of. 135 readings. The Cutler,

Maine station ( 17.8 KHz) was used and the in-cphase dip angle

readingsCexpressed as tangent #) are plotted at l inch e 60 tan#,

A summary of the EM-16 specifications is appended.

Results

The VLF-EM survey results are plotted on Figure 2. Two continu

ous and parallel high-angle in-phase cross-over anomalies strike

east-south-east across claims L. 550833 an 32. These sharp

features coincide with or fall near the high tension power line.

Three other cross-overs at L/fOW, IS, L36W,2S, and L32W,5S lie

near another power line that runs along highway 66. All cross

over anomalies are interpreted to be caused by cultural effects.

Magnetometer Survey

A magnetometer survey was completed on May 26 - 27, 1982 to assist

the geological interpretation. A Sharpe Instruments MF-1 fluxgate

magnetometer was used and readings were taken every 50 feet along

the crosslines for a total of 260 readings. Daily magnetic read

ings were tied to the base, etation and adjusted for diurnalv.drift,

In addition, secondary base stations along the baseline at cross-

line intersections were read as each loop was completed.

A summary of the MF-1 specifications and operating procedures

is appended. Results

The magnetometer survey results are plotted on Figure 3. Diurnal

variations were only 25 gammas for the survey.

- k -

The results show a general east to east-southeast magnetic trend

through L.550832 and 33 with a few peaks exceeding 3000 gammas.

This trend parallels the interpreted.geological strike for the

area and likely represents magnetite-rich concentrations within

the trachytic volcaniclastic horizons. The somewhat isolated

magnetic highs in L.495894 as at line 36W,?N and 9N; line 32W,

13.5N, 16N, 18N and 20N may reflect a diabase dyke that cuts

through the claims ( ODM Map 53a, Geology of Lebel Twp.).

CONCLUSIONS

VLF-EM and magnetometer surveys have been completed over 3

claims that form part of Tower Gold Resources' Commodore Group

in Lebel Township. The work has indicated an east-southeast

magnetic trend that likely reflects the geological stMke, and

electromagnetic features caused by cultural effects.

Follow-up exploration will include detailed mapping and sampling

to test for gold horizons and/or structures.

MODEL MF-1 FLUXGATE MAGNETOMETEROpcrotion of the Meter1.) Remove all magnetic objects from operator's person, e.g. v keys, coins, buttons, etc.

Zippers should be non-magnetic.2.) Connect Battery Cable, Figure 6, to magnetometer receptacle on bottom of main hous

ing. This connection must be secured by lock-ring. 3/j Attacn battery pack(Fig. 5) either in back pocket or on belt behind operator.4.) Switch on Main Switch (Fig. 3) to first position, which is the battery check. Indicating

meter needle should rest within red arc. Replace batteries if reading below red arc.5. )Latitude Adjustment -To adjust the latitude setting toread O gammas is a simple operation.

j. After indicating meter needle (fig. 2)shows voltage okay, switch Main Switch(Fig.3) ;o next position which is the positive reading with the Range Switch (Fig. 1) set it the lOOK step. (100,000 gamma range)

D. II needle goes full arc to left past O, switch main switch (Fig. 3) to last position which is the negative reading range.

c. Figures 10 and 9 indicate the latitude adjustment controls * Coarse control Is Fig. 10 and Fine control is Fig. S. If scale reading is more than t 7,000 gammas rotate coarse control (Fig. 10) in steps of 7,000 and switch range down to more sensitive ange until scale is reading less than t 7,000 gammas. Remove protection cap on fine control (Fig. 8) by pulling straight off. Then rotate fine control switch (Fig. 9) intil scale reading is O gammas. Check reading by switching main switch from positive to negative (or vice versa) to ensure O reading both polarities. Replace fine control protection cap.

6.) Calibration * This meter is calibrated at the factory prior to delivery. Field tests show that only by severe misuse (i.e. constant dropping, rough handling, improper shipping) can the calibration of this instrument be effected. It Is therefore not necessary tore* calibrate in the field and if through misuse calibration becomes necessary, the meter should be returned to the factory. *AII parts are guaranteed against defect for a period of one year and will be replaced free of charge.

"This guarantee does not apply to batteries or the connecting cable.7.) Trouble Shooting - Under normal conditions the only field problem will be batteries or

the connecting cable. If after completion of step (4) under "Operation of the Meter" the meter still does not indicate voltage, check cable for faulty connection or broken cable. If after this procedure, meter still does not indicate current, return unit immedi ately to your supplier or directly to the factory.

Regional Latitude SettingsNormally each unit is pie-set at the factory for the Northern Hemisphere. However, if the unit is required for Equatorial or Southern Hemispheric regions, the unit will be pre-set it the factory for these areas. If i unit is going from one of the ibove regions to mother, res, t instructions will be supplied on request.Field Procedure1.) Se le c; Base Control station. This station should be selected in relation to one or

. :ih of two things.i. General magnetic background (i.e. not anomalous) if possible. :. Accessibility in relation to area being surveyed.

2.) Set siijj.ietometer to read between O and 200 gammas, (F or contouring and to avoid small negative readings, an arbitrary value of IOOO-80Dgammas should be added to allreadings.

3. j For effective diurnal control, control stations should be permanently marked and read* inps should be taken at the same height and location each time: a simple method Is lo i..ye the control stations' pickets hammered into the ground with the top about wiist weight. Rest the probe end of the magnetometer on the top of the picket, In barren country, a mound or Urge piece of rock or some other material should be used.

4.) Continue survey the same, as any other method of magnetic surveying.5.) Remove and replace Silica-Gel (Fig. 7) when deteriorated. The silica gel Is located

in the removable probe housing. The Silica bag should not be placed on the bottom of the probe housing.

6.; De not pass powerfuj magnet closer than l foot to instrument.'jjring winter operation, batteries should be kept in pocket or under parka. V.arning: - Do not leave batteries in battery case when'unit is being stored. Always be

sure meter is turned off after use. Disconnect battery cable when meter not in use.""

PRINCIPLES OF OPERATION

The VLF-transmitting stations operating for communications with submarines have a vertical antenna. The Antenna current is thus vertical, creating a concentric horizontal magnetic field around them. When these magnetic fields meet conduce tive bodies in the ground, there will be secondary fields " radiating from these bodies. (See Ffgures 3 fi. 4). This equipment measures the vertical components of these secondary fields.

The EM16 is simply a sensitive receiver covering the fre quency band of the VLF-transmitting stations with means of - measuring the vertical field components.

The receiver has two inputs, with two receiving coils built into the instrument. One coil has normally vertical axis and the other is horizontal.

The signal from one of the coils (vertical axis) is first minimized by tilting the instrument. The tilt-angle is calibrated in percentage. The remaining signal in this coil is finally balanced out by a measured percentage of a signal from the other coil, after being shifted by 906 . This coil is normally parallel to the primary field,(See instrument' Block Diagram - Figure 2).

Thus, if the secondary signals are small compared to the primary horizontal field, the mechanical tilt-angle is an accurate measure of the vertical real-component, and the - compensation fl/2-signal from the horizontal coil is a measure of the,quadrature vertical signal. :

Orientation S Taking a Reading

The direction of the survey lines should be selected approxi mately along the lines of the primary magnetic field, at right angles to the direction to the station being used. Before starting the survey, the instrument can be used to orient one self in that respect. By turning the instrument sideways, the signal is minimum when the instrument is pointing towards the station, thus indicating that the magnetic field is at right angles to the receiving coil inside the handle.(Fig.11).

To take a reading, first orient the reference coil (in the lower end of the handle) along the magnetic lines.(Fig.12) Swing the instrument back and forth for minimum sound intensity in the speaker. Use the volume control to set the sound level for comfortable listening. Then use your left hand to adjus^ the quadrature component dial on the front left corner of the. instrument to further minimize the sound. After finding the minimum signal strength on both adjustments, read the inclino meter by looking into the small lens. Also, mark down the quadrature reading.

While travelling to the next location you can, if you wish, keep the instrument in operating position. If fast changes in the readings occur, you might take extra stations to pinpoint accurately the details of anomaly.

The dials inside the inclinometer are calibrated in positive and negative percentages. If the instrument is facing 180O from the original direction of travel, the polarities of the readings will be reversed. Therefore, in the same area take the readings always facing in the same direction even when travelling in opposite way along'the lines.

The lower end of the handle, will as a rule, point towards the conductor. (Figs. 13 6. 14) The instrument is so calibrated that when approaching the conductor, the angles are positive in the in-phase component. Turn always in the same direction for readings and mark all this on your notes, maps, etc.

THE INCLINOMETER DIALS

The right-hand scale is the in-phase percentage(ie. Hs/Hp as a percentage). This percentage is in fact the tangent of the dip angle. To compute the dip angle simply take the arc tangent of the percentage reading divided by 100. See the conversion graph on the following page.

The left-hand scale is the secant of the slope of the ground surface. You can use it to "calculate" your distance to the next station along the slope of the terrain.

Page 21

(1) Open both eyes.

(2) Aim the hairline along the slope to the next station to about your eye level height above ground.

(3) Read on the left scale'directly the distance necessary to measure along the slope to advance 100 (ft) horizon tally.

We feel that this will make your reconnaissance work easier. The outside scale on the inclinometer is calibrated in degrees just in case you have use for it.

PLOTTING THE RESULTS

For easy interpretation of the results, it is good practice to plot the actual curves directly on the survey line map using suitable scales for the percentage readings. (Fig.15) The horizontal scale should be the same as your other maps on the area for convenience.

A more convenient form of this data is easily achieved by transforming the zero-crossings into peaks by means of a simple numerical filtering technique. This technique is described by D.C. Fraser in his paper "Contouring of VLF-EM Data", Geophysics, Vol. 34, No. 6. (December 1969)pp958-967. A reprint of this paper is included in this manual for the convenience of the user.

This simple data manipulation procedure which can be imple mented in the field produces VLT-EM data which can be contoured and as such provides a significant advantage in the evaluation of this data.
