REPORT ON MAGNETOMETER AND VLF-EM SURVEY

COSTELLO LAKE AREA, SKEAD TOWNSHIP, ONTARIO

INTRODUCTION

Linecutting followed by a magnetometer and VLF-EM

survey was carried out on a block of claims west of Costello

Lake in Skead Township, Ontario. The results are shown on the

accompanying maps. ft

LOCATION, ACCESS AND OWNERSHIP

The claims are located in parts of Lots 9 to 11,

Concession 4; Lots 10 and 11, Concession 3 and Lot 11, Concession

2 in Skead Township, District of Temiskaming, Ontario. Claims

are numbered L57848 to 578355 and L561731 to 561752 all inclusive.

They are recorded in the name of Superior Northwest Inc,, Box Ill6

Sault Ste. Marie, Ontario and Lucien Lacasse, Larder Lake, Ontario.

Access is by logging roads which lead from Highway 624

about 8 miles south of Larder Lake, Ontario.

PREVIOUS EXPLORATION

Previous work has consisted of some pits, trenches and

stripping for which no records could be found.

GEOLOGY

The property is underlain by a volcanic sequence of

rocks, mostly mafic volcanics with narrow felsic volcanic bands

on the west side of the property,- A band of ultramafic rocks runs

through the centre of the claim group, trending north-south to

north-west south-east. On the eastern part of the claims, the

volcanics are overlain by younger sediments of the Cobalt series.

SURVEY PROCEDURE

A baseline was cut at approximately N 50 W - S 50 E

from a tie line cut southwest from a baseline at Mageau Lake.

Crosslines were then run at 400-foot intervals normal to the base

lines. All lines were chained and picketed at 100-foot intervals.

Magnetometer readings were taken with a Barringer GM-122

Proton Precession Magnetometer at 100-foot intervals. The looping

method was used for control of diurnal variation. In this method

a base station is selected and readings taken along lines describing

a loop, arriving back at the starting base station in less than two

hours. A second loop is then started using either the same base

station or another which is tied to the previous loop. Readings

are then corrected for diurnal variation by assuming the time

between readings is the same and distributing any variation equally

among the intervening readings. No correction was applied less

than the accuracy of the base station reading.

A VLF-EM survey was carried out using a Phoenix VLF-2

instrument set to the signal from Annapolis, Maryland (21.4 KHz).

Readings were taken at 100-foot intervals using the procedure out

lined in Appendix I. The looping method was used for control of

variation, the same as described for the magnetometer survey,

excepting that the time was noted for each station.

Because of stations being off the air, more than half

of the survey was conducted with a single station and repeated

for the second station.

RESULTS AND CONCLUSIONS

Magnetometer

Magnetic readings are high to the east of the baseline/

which is underlain by ultramafic rocks. The magnetic survey

clearly outlines the areas underlain by ultramafics.

VLF-EM

The VLF-EM survey shows a large number of anomalies

parallel to the trend of the ultramafics. The probable cause of

these anomalies is serpentinization within the ultramafic rocks.

Anomalies along the west part of the claims are in mafic to felsic

volcanic rocks and warrant surface prospecting or checking with

other geophysical methods.

MODEL MF-1 FLUXGATE MAGNETOMETEROperotion of the Meter1.) R emove all magnetic objects from operator's person, e.g. 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.) Attach 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.

a. After indicating meter needle (f ig.2) shows voltage okay, switch Main Sv itch(Fig.3) to next position which is the positive reading with the Range Switch (Fig. l)set at the 100K step. (100,000 gamma range)

b.If needle goes full arc to le-ft 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. 9. If scale reading is more than 7 ,000 gammas rotate coarse control (Fig. 10) in steps of 7,000 and switch range down to more sensitive range until scale is reading less than i 7,000 gammas. Remove protection cap on fine control (Fig. 8) by pulling straight off. Then rotate fine control switch (Fig. 9) until scale reading is p gammas. Check reading by switching main switch from positive to negative (or vice versa) to ensure Dreading 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, roigh handling, improper shipping) can the calibration of this instrument bi effected. It is therefore not necessary to re 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 he leplaceo 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 pre-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 at the factory for these areas. If a unit is going from one of the above regions to another, reset instructions will be supplied on request. Field Procedure1.) Select Base Control station. This station should be selected in relation to one or

both of two things.1. General magnetic background (i.e. not anomalous) if possible.2. Accessibility in relation to area being surveyed.

2.) Set magnetometer to read between O and 200 gamrcas. (For contouring and to avoid small negative readings, an arbitrary value of 1000-oOOjamma? should be added to all readings.

3.) For effective diurnal control, control staliyns should be permanently marked and read ings should be taken at the same height and location each time; a simple method is to have the control stations' pickets hammered into the ground with the top about waist height. Rest the probe end of the magnetometer on the top of the picket. In barren country,a mound or large piece of rock or some other material should be used.

4.) Continue survey the same, as any othe'. method of magnetic surveying.5.) Remove and replace Silica-Gel (Fip..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.) Do not pass powerful magnet closer than l foot to instrument.7.) During winter operation, batteries '-hould bc kept in nocket or under parka. ' Warning: - Do not leave batteries i. battery case when unit is being stored. Always be-

be sure meter is turned off otter use. Disconnect battery cable when meter not in uie.

CONDUCTOR DIRECTION ARROW SPEAKER

This is a rugged, simple to operate, ONE MAN EM unit. It can be used without line cutting and is thus ideally suited for GROUND LOCATION OF AIRBORNE CONDUCTORS and the CHECKING OUT OF MINERAL SHOWINGS. This instrument utilizes higher than normal EM frequencies and is capable of detecting DISSEMINATED SULPHIDE DEPOSITS and SMALL SULPHIDE BODIES. It accurately isolates BANDED CONDUCTORS and operates through areas of HIGH HYDRO NOISE. The method is capable of deep penetration but due to the high frequency used its penetration is limited in areas of clay and conductive overburden.

The DIP ANGLE measurement detects a conductor from a considerable distance and is used primarily for locating conductors. The FIELD STRENGTH measurement is used to define the shape and attitude of the conductor.

INSTRUCTIONS FOR OPERATION OP THE

RADEM VLF-EM RECEIVER

(1) Transmitter Stations

The VLF Communication Broadcast stations are positioned throughout the world. At present, 12 of these stations broadcast steadily except for maintenance periods usually of 1/2 to 1/3 days per week. The RADEM receives any 1 o f these sitations with selection by means of a switch. The usable range of the stations varies widely with power and transmission conditions but is usually between 1000 and 5000 miles. Two types of signals are broadcast "keyed" (on and off) and "frequency shift" (FM). Frequency shift provides a steady signal and is most suitable for Field Strength measurements, When a "Keyed" signal is used the receiver must be switched to the keyed signal "K" position for Field Strength Measurements.

A station should be selected that is located in the same direction as the regional strike. If in doubt of the geological strike two orthogonal stations should be read.

(2) Field Measurements

(a) Dip Angle of Resultant Field

Technically the angle in degrees, from the horizontal, of the major axis of the polarization ellipse. This is the easiest measurement to make since it is not dependent on changes in signal strength. The dip angle measurement detects a conductor from a considerable distance - from several hundred to several thousand feet. Direct plotting of the dip angles often does not clearly define the shape or position of the conductor. If strong regional effects occur the conductor may not produce a cross-over and may be defined only by a sharp variation in dip angles.

Two methods are available to overcome this defect in the dip angle measurement: (1) Field Strength measurement and (2) treatment of the Dip Angle data by means of a simple process deve loped by D. C. Fraser and described in Geophysics Vol. 34, #6, December 1969.

Page 12: RPT ON MAG & VLF-EM SUR COSTELLO LAKE AREA SKEAD TWP€¦ · COSTELLO LAKE AREA, SKEAD TOWNSHIP, ONTARIO INTRODUCTION Linecutting followed by a magnetometer and VLF-EM survey was

' ,Field Strength Measurements

These measurements do not detect the conductor until they are almost above it. Thus they are independent of regional trends and accurately define the shape and boundries of the conductor. This is simply achieved by contouring the Field Strength readings. Either the Resultant Field Strength or Horizontal Component of the Field Strength are measured, usually the latter, since it is easier to read.

The Field Strength of a VLF station varies with time thus a base station must be established and drift corrections applied as in a magnetic survey. Drift is particularly rapid during sun rise and sunset (50 % per hour) and reading is not advised during this period. The primary base station is usually located in a non conductive area where the dip angle is near "O" and the out-of-phase signal is also "O" - the Field Strength is set at 100 at this station and this is the Normal Field Strength standard for the survey.

(c) "Out-of-Phase" Field Strength Measurement

This is in effect the out of phase component perpendicular in direction to the resultant field. The measurement is without sign and is sensitive to very low orders of conductivity. It is simply the minimum reading of the Field Strength meter obtained when reading the Dip Angle. It is expressed in terms of percent of the normal Field Strength. It is not usually recorded unless very low orders of conductivity are of interest.

FIELD PROCEDURE:\

(1) Make sure the "Normal" - "K" switch is in the normal position.

(2) Hold the RADEM with the meter faces horizontal. Rotate the instrument in a horizontal plane, by moving the body until a null is observed on the Field Strength meter. This aligns the base of the instrument in the direction of the VLF field and the operator will be facing in the direction of the transmitting station.

(3) Raise the instrument such that the meter faces are vertical and rock it back and forth until a minimum is obtained on the Field Strength meter (switch on 0-300 scale). This minimum is the"0ut-of- Phase" reading. Holding the instrument at the minimum position read the inclinometer for the Dip Angle reading. Note that the arrow through the "o" of Crone points towards the conductor. If this is north then the inclinometer reads 17 0 N and the conductor is towards the north. This convention leaves no doubt as to where the conductor is located. The operator must be able to recognize between a true cross-over and a false cross-over and this convention is established to help simplify this matter.

- 3 -

(4) For a Horizontal Field Strength measurement hold the meter face horizontal and rotate this instrument in a horizontal plane until a maximum reading is obtained. This will be approximately in a direction at right angles to the operator. For a Resultant Field Strength measurement - this is the maximum Field Strength reading obtainable - and is obtained by holding the RADEM at right angles to the operator and inclined at the same angle as the dip angle.

(5) For a Field Strength reading with a "Keyed" VLF signal move the "Normal" - "K" switch to the "K" position. It must be returned to the "Normal" position for the iip angle measurement.

Since the Field Strength varies with time this reading must be tied to a base station with drift corrections applied similar to a magnetometer survey. If possible the primary base station should be established in a non-conductive area where the dip angle is near "O" with out of phase near "O" and where the volume control is adjusted such that the Field Strength reading is "100".

Dear Sir:

Enclosed are two copies of a Notice of Intent with statements listing a reduced rate of assessment work credits to be allowed for a technical survey. Please forward one copy to the recorded holder of the claims and retain the other. In approximately fifteen days from the above date, a final letter of approval of these credits will be sent to you. On receipt of the approval letter, you may then change the work entries on the claim record sheets.

For further information, if required, please contact Mr. F.W. Matthews at 416/965-1380.

Yours very truly,

Notice of Intent

for Technical ReportsOntario

1983 08 16

2.5495

An examination of your survey report indicates that the requirements of The Ontario Mining Act have not been fully met to warrant maximum assessment work credits. This notice is merely a warning that you will not be allowed the number of assessment work days credits that you expected and also that in approximately 15 days from the above date, the mining recorder will be authorized to change the entries on his record sheets to agree with the enclosed statement. Please note that until such time as the recorder actually changes the entry on the record sheet, the status of the claim remains unchanged.

If you are of the opinion that these changes by the mining recorder will jeopardize your claims, you may during the next fifteen days apply to the Mining and Lands Commissioner for an extension of time. Abstracts should be sent with your application.

If the reduced rate of credits does not jeopardize the status of the claims then you need not seek relief from the Mining and Lands Commissioner and this Notice of Intent may be disregarded.

If your survey was submitted and assessed under the "Special Provision-Performance and Coverage" method and you are of the opinion that a re-appraisal under the "Man-days" method would result in the approval of a greater number of days credit per claim, you may, within the said fifteen day period, submit assessment work breakdowns listing the employees names, addresses and the dates and hours they worked. The new work breakdowns should be submitted direct to the Lands Management Branch, Toronto. The report will be re-assessed and a new statement of credits based on actual days worked will be issued.
