ABSTRACT

l.O ABSTRACT

This report covers a combined HEM, Magnetometer and VLF Airborne Geophysical Survey over the Dawson Road Lots property shown on the location map included in this report - NTS Sheet 52A/12.

The survey was flown for Jalna Resources Limited {Jalna) by Geotech Ltd. (Geotech) between December 28, 1984 and January 25, 1985. The field crew mobilized from Markham to Thunder Bay on December 28, 1984. The base of operations for the survey was Shabaqua, Ontario. Fuel was trucked by Geotech from Thunder Bay to the base at the Timberland Motel. The installation was completed and the first test flight made on January 2, 1985; however, severe weather, instrumentation failures, especially with the magnetometer, and pilot inability to handle the HEM bird hampered the efficiency of the survey. A brief summary of the field problems is contained within this report. Severe cold {-40 C) hampered the operation of the data acquisition system throughout the survey. Visual navigation was used with flight path recovery done using a video system. Examples of the analog presentation are contained in this report, as well as instrument and survey specifications.

Data compilation for the survey was done at the facilities of Data Plotting Limited. Difficulty was encountered in loading the survey magnetic tapes onto the main frame computer. It j s felt that large temperature differentials between the recording and reading environments may account for some of the tape loading problems observed at Data Plotting Ltd. and numerous software routines had to be written in order to handle the UDAS survey format. Heavy work load at Data Plotting has necessitated the long turn-around time for final map presentation.

Additional information may be obtained by contacting Geotech.

2.0 SURVEY SPECIFICATIONS

2.1 A total of about 76 miles were required for the survey. Claim

M blocks covered are shown in Appendix B and on the survey location

map. Appendix A.

l 2.2 Traverse lines were flown in the direction as shown on the

location map. Traverse lines were flown 660 feet apart. Where

adjacent lines are more than 1000 feet apart for a distance of

more than l mile, traverse lines were reflown. Preliminary

flight path recovery was done in the field.

2.3 No tie lines were flown for the survey.

2.4 Nominal helicopter survey altitude was 200 feet euch that the EM

sensor coils were approximately 100 feet above mean ground level.

Magnetometer and VLF sensor clearance was about 160 feet since

this drogue was located about midway onthe HEM tow cable.

2.5 Traverse lines would have been reflown if the sensor clearance

exceeded 225 feet above mean terrain level over a distance

greater than l mile, provided that the safety of the helicopter

and the 'bird 1 would be maintained. A radar altimeter accurate

to 5 96 was used to maintain sensor clearance.

2.6 The pilot's decision as to system airworthiness and as to safe

operating conditions was binding throughout the survey.

2.7 Nominal traverse line survey airspeed was about 60 mph.

2.8 Navigation for traverse lines was visual, based on airphoto

mosaics provided by Geotech.

2.9 Flight path recovery was done initially in the field using the

l SURVEY SPECIFICATIONS

Geotech Video Datacam flight path recovery system.

l 2.10 A Geotech EMEX-1 Four Frequency HEM System was used having the

following technical specifications:

l Coil separation: 6.45 metres.

m Vertical Coaxial frequencies - 933 Hz and 4157 Hz

Horizontal Coplanar frequencies - 995 Hz and 4427 Hz.

l The EM system was sampled at 0.1 seconds. Instrumentation noise

was maintained as low as possible. It is recognized that varying

l atmospheric conditions, turbulence effects, and cultural effects

M create noise levels that typically excfeed 6 ppm. Geotech would

refly traverse lines where the noise level exceeded 4 ppm. Noise

l levels throughout the survey were well below this level.

In phase and quadrature components were recorded for each coil

g pair, thus 8 channels of EM information were recorded in both

analog and digital form.

" A 60 Hz power line monitor was recorded in both analog and

j digital form.

No atmospheric monitor was recorded.

l External calibrations and phasing were done at the start and end

of the survey. Internal Q-coil calibrations were done at the

start and end of each survey flight. All calibrations were

H recorded on magnetic tape. Drift rates for calibrations on all

EM channels were minimal over -the duration of the survey.

l 2.11 A proton precession-type magnetometer with a resolution of l

gamma sampled at once per second was used for the survey. Noise

l

l

l l l l l l l l l l l l l l l l l l i

5 SURVEY SPECIFICATIONS

envelope of the magnetometer was not to exceed 2 gammas at survey

altitude. A G803 proton magnetometer was used throughout the

survey.

2.12 The VLF system was a Totem-2A. Stations recorded would be NSS

(Annapolis) or NLK (Seattle). Survey operations could continue

using NAA (Cutler) as a substitute for NSS. The survey was flown

using NAA as the line frequency and NLK as the ortho frequency *

due to logistical considerations.

Noise envelope on both in phase and quadrature profiles was 2 .5%

or less.

In phase and quadrature components of both the line and ortho

frequencies were recorded in both analog and digital form. Only

one VLF map would be produced using the line information.

2.13 Data was recorded in both analog and digital form. Eight

channels of EM, four channels of VLF, two channels of

magnetometer, one 60 Hz monitor, and one radar altimeter were

presented in analog form using a UDAS-100 printer.

Analog scales were to be approximately as follows:

Altimeter 3 m/mmEM 2 ppm/mmVLF 2. 5* per mmMagnetometer (fine) 5 gammas/mmMagnetometer (coarse) 50 gammas/mm60 Hz varying amplitude

Refer to actual example in this report.

Fiducial marks were presented once every second. Time and actual

numerical fiducial numbers were printed at the start and end of

SURVEY SPECIFICATIONSl~ each traverse line. The value of the actual magnetometer reading

l was printed at the end of each traverse line automatically.

Fiducial numbers and time were also impressed on the video system

l to allow correlation of the geophysical data with the flight

path.

" The digital acquisition system recorded data from all sensors

l continuously while on traverse line survey. Time, fiducial and

line number were also recorded. Specifications required that the

l geophysical data be recorded on 9 track IBM-compatible magnetic

tape. The UDAS-100 utilizes a read-after-write verification

process to ensure the integrity of the recorded data.

l 1.14 A base station magnetometer was required throughout the survey.

Time synchronization was maintained within +X- l second by using

l a quartz watch. The base station was recorded in analog form

only.

B Survey operation would be discontinued when magnetic variations

j at the base station exceeded 10 gammas per minute or where the

base station profile exceeded 20 gammas from any 5 minute chord.

I No survey flying was lost due to base station activity.

l l l

3.0 DATA COMPILATION

l 3.1 Compilation was done at scale l inch to .1,320 feet on screened

"greyflex" base maps prepared from the navigation mosaics.

l 3.2 The EM data was plotted as profiles on flight path maps, using

m different profile weights for the in-phase and quadrature

components. Separate maps were prepared for each coil pair and/or

l each frequency used. In addition, EM anomalies were indicated by

appropriate symbols bearing information as to interpreted

l conductance and in-phase signal strength utilizing specific EM

m frequencies as noted. Four EM maps were produced.

3.3 The VLF EM data was presented on flight path maps as contours of

the total fiejd and profiles of the quadrature component. One

VLF map was produced .

l 3.4 The magnetometer data was levelled and presented as contours on

j the flight path maps. No filtered magnetic contour maps were

required. One magnetometer map was produced.

l 3.5 In addition to the above products, Geotech will supply annotated

and bound analog records, together with all other raw and

l intermediate survey data as required by Jalna.

B 3.6 Geotech will also supply final digital magnetic profile tapes

containing all of the recorded data (edited and levelled where

l necessary(, time, and XY information. In addition, a gridded

magnetic tape of the contoured total magnetic field data will be

l supplied, with a grid interval of approximately 160 feet.

3.7 "A report will be prepared describing the survey, instrumentation,

6.0 FIELD LOGISTICS

At the start of the project it was originally Geotech 1 s intent to

J utilize a Bell 206B supplied -from Nipissing Helicopters in North Bay,

B Ontario. MOT approval was obtained for this helicopter, only to find

" that at the last minute Nipissing was forced to supply the designated

l helicopter to another client. Fortunately, Lakeland Helicopters, out

of Thunder Bay, were able to supply a similar 206B. MOT approval was

l obtained and logistics reorganized to accommodate the installation in

Thunder Bay.

B The installation crew consisted of Victor Cole and Bob Langsdon,

B who mobilized from Markham on December 28, 1984, carrying all required

items in the Geotech survey cube van. This cube van was custom

l modified to carry two EMEX birds on its roof. Complete spares and

accessories are carried in the stand-up van box. Noil Punstel joined

l the crew on Decmeber 30th. All crew members arrived in Thunder Bay on

m December 30 and the installation was started tho same day. The

Geotech cube van had arrived at Bearskin Hangar located at Thunder Bay

l airport early in the afternoon.

The installation was completed on January 2, 1985. Delays were

l encountered since our personnel were denied access to the hangar on

j the January 1st holiday. The crew worked outside on this day.

Another helicopter rear door had ta be flown in from Sudbury since the

bubble window on the existing door could not be modified to allow for

tow cable entry. The MOT approval did not allow for modification to

12 FIELD LOGISTICS

the bubble window. Unfortunately the first door shipped in was for

l the wrong side of the helicopter and a second door had to be shipped.

The first test flight was made on January 2, 1985, for

l airworthiness and aerodynamic performance of the system in keeping

M with MOT requirements. It was demonstrated on this flight that the

GEM Systems Inc. GSM-8BA magnetometer did not appear to work within

l specifications with the EMEX-1 system operational specifications. A

second GSM-8 was sent from Toronto but subsequent testing showed

l excessive noise in the airborne environment. The combined

| VLF/magnetometer bird was designed specifically for the GSM-8BA sensor

which is physically very small and lightweight. The aerodynamics of

l this bird appeared ideal under flying conditions but the first pilot

had difficulty with the large EMEX-1 bird. Test flying was further

l hampered by bad weather. While still in Thunder Bay, three days were

lost due to heavy winds and/or snow storms. Fuel logistics for

* remobilization were organized during these weather days.

l Initial attempts to make the magnetometer operational proved

fruitless. No explanation could be readily found since the system

l appeared to work fine in Markham during pre-shipment ground testing.

Software routines developed solely for the use of the GSM-8BA

" magnetometer limited the change-over to a different magnetometer. The

l larger physical size and increased weight (20 Ibs) of the Geometrics

sensor forced an in-field redesign- and construction of a new VLF/mag

l bird. The installation crew spent many hours constructing a new

VLF/mag bird from materials that were locally available in Thunder

l

l

l 13 FIELD LOGISTICS

Bay. The new VLF/mag bird that was produced weighed about 70 Ibs more

l than the original design that used the Gem mag. This was to effect

the overall efficency of the survey by reducing fuel capacity and

l hence helicopter range. Subsequent flying also demonstrated that the

Geometrics mag was susceptible to interference from the HEM system.

This resulted in overall degraded performance of the magnetometer,

l Although the data was within the survey specifications, it is the

opinion of the writer that improved performance could be obtained if

f additional modification were made to the G803 mag preamplifier to

remove the effects of the EM fields. This task is quite difficult and

could not be attempted in the field.

l During this stage, Lakeland Helicopters was unfortunately

required to switch pilots. The new pilot was unable to fly the EMEX-1

l bird and numerous hours were spent teaching him to fly the geophysical

system. During this flying time the radar altimeter failed and had to

be returned to Toronto for warranty repairs. Geotech wat; able to

B provide immediately a replacement radar altimeter with no lost time in

l

l

the field: both Nordair and Air Canada have almost daily flights to

Thunder Bay from Toronto.

The crew was joined by Mr. Ed Morrison, President of Geotech Ltd.

who spent 4 days in Thunder Bay on the calibration of the EM system

and total system debugging. Pilot training took a considerable amount

of time and effort on the part of the field crew. Survey flights were

l attempted using Thunder Bay as a base of operations but again the

radar altimeter failed and had to be returned to Toronto for repairs.

l

l


l

l

m Time was also spent checking out the second HEM bird which was on site

l for use as a back-up. During this time period a second G803

magnetometer was dispatched from Toronto and was used for parts to get

l the original G803 operational .

On January 16 the helicopter and crew mobilized to Shabaqua,

Ontario whcih was to be the base of operations for the remained of the

l survey. Mr. Morrison and Neil Punstel returned to Markham since the

survey system was now field ready. Mr. Chester Bassani arrived in

l Shabaqua on the 16th to function as overall Party Leader for the

remainder of the flying. Initally time was lost due to severe weather

" that prevented flying. Lakeland once again changed pilots setting the

j project back. Survey flying was attempted with the new pilot but this

proved to be total unacceptable. The HEM bird was almost lost and

l physical damage to the nose cones resulted from the bird being landed

on a fence. This third pilot was replaced with Mr. Dave Blackburn

l whose previous experience proved to be invaluable. Mr. Blackburn was

M to remain with the survey crew throughout the remainder of the job.

Visual navigation in certain parts of the area proved to be

l difficult due do the fact that trees had been removed and new roads

and buildings added. In order to find good navigational features to

m l ine up on at the end of the traverse lines, flight lines were

m extended significantly in the south end of the area. The field crew

was joined by Mr. Jim Misener of Patterson, Grant and Watson and Mr.

l Paul Wessler on January 28 to review survey data. The decision was

made to refly the area in order to improve navigational control and


improve upon record quality of the magnetometer and HEM data. Three

l major power lines cross the survey area and detract from the HEM

system performance. Mr. Misener returned to Toronto and Mr. Wessler

l remaind to supervise and compile existing survey data.

m Throughout the remaining flying, the project was hampered by the

cold weather and the performance of the data acquistion system. Every

l means possible was used to keep the unit warm enough (-10 C) in order

to ensure that magnetic data was being correctly recorded,

l Unfortunately the Janatrol heater aboard the helicopter failed and

m t ime was again lost. As the helicopter cooled off the data

acquisition system would begin to fail destroying the analog

l information due to incorrect printer operation. The decision was made

to refly the entire survey area in attempts to improve upon the

l navigation with Mr. Chester Bassani as navigator. Mr. Langsdon left

. the field operation and returned to Toronto.

* During the reflying of the survey, the Totem 2A failed and had to

l be returned to Toronto for repairs. A quick turn around was

accomplished and only one day was lost due to this failure. Various

l survey lines were reflown to check the performance of the unit upon

its return to the survey crew.

All survey data was returned to Toronto and presented to Data

U Plotting for final compilation. Analog records were given to

Patterson, Grant and Watson for classification and anomally picking.

l

l

l

l

Numerous new software routines had to be written at Data Plotting to

handle the UDAS format resulting in exceptionally long delivery time.

Swept-frequency Electromagnetic System Development for NASA.

COMPANY PROFILEGeotech Ltd. is a private Canadian com pany with its head office in Markham (Toronto) Ontario. The principle acti vities of the company are the develop ment, design and manufacture of sophisticated multifrequency electro magnetic systems for the mineral exploration community. Our helicopter- borne systems are ideally suited to base metal exploration and the search for ground water. The EMEX-1 four fre quency HEM system is used by the majority of Canadian contract survey companies for mineral exploration within North America.

As a manufacturer of geophysical instru mentation and scientific apparatus, Geotech places a heavy emphasis on research and development. This empha

sis has led to large scale development projects on behalf of the United States National Aeronautics and Space Admin istration Centre (NASA); the National Research Council of Canada; and the Geological Survey of Canada as well as the Department of Energy, Mines and Resources. Geotech's expertise in elec tromagnetics will continue to provide new instrumentation for the Earth Science community on an international level with expanded applications beyond mineral exploration and civil engineer ing. Geotech is currently designing a unique airborne method of measuring the depth of coastal sea water beneath Arctic ice for the Canadian Hydro graphic Service. When completed this cost effective system will provide the first airborne method of simultaneously measuring ice thickness and water depth accurately and independently.

EMEX Series Electromagnetic System Applications

Geological Mapping

EMEX System Description^^^^The Geotech EMEX Series Electromagnetic Systems represent state-of-the-art technology in the use of multifrequency, multicoil orientation.

The use of many discrete frequencies, along with multigeometry information allows the user to maximize his interpretation capabilities via the sophisticated computer interpretation software now available.

The range of available frequencies for the EMEX Series and the standard multigeometry configuration enables each system to be custom designed for any specific application.

The frequencies may be selected from 80 Hz to 50 kHz which is the widest range available for any airborne EM system.

This technology lends itself to more applications than the traditional role of metallic conductor detection. Large scale, fixed wing single geometry systems inherently energize a large volume of the ground due to the large transmitter/receiver separation, thereby causing pooi resolution. The EMEX Series, with its multifrequency, multigeometry configuration, is operated close to the ground by a helicopter and energizes a much smaller ground volume which results in the generation of high resolution data.

The high resolution multifrequency data, obtained in multiple planes, has made the EMEX Series the most effective airborne instrumentation available for geological mapping and conductor discrimination.

Geological mapping has been one of the areas of significant growth in the application of airborne EM systems over the past few years. This has been a direct result of the development of multifrequency EM hardware along with the simultaneous development of interpretive software. The EMEX Series has been developed specifically with geological mapping as one of its major applications.

A serious source of error in geological mapping with EM surveys is base line drift in the recorded data. Geotech has incorporated into the design of the EMEX Series construc tion techniques and electronic circuits to minimize base line drift to the greatest extent possible. This eliminates, in most cases, the need to use up valuable survey time flying the system out of ground effect just to establish the base line drift.

Resistivity mapping and the thickness of one or more layers of a horizontally stratified conducting media may be determined using data collected by the EMEX System. These data may be presented in the form of contoured maps to delineate the overburden and rock types.

Geological mapping may be used to help delineate any geological feature where a resistivity contrast exists.

Mineral Prospecting_______Over the past 30 years, helicopter EM system development has progressed steadily. From penetration depths of 30 to 60 m with one frequency, we have now achieved penetrations of up to 150 m and greater with four frequencies.

During the past 10 years in particular, we have advanced from single frequency systems, first to dual, and then to three and four frequency systems. Finally, today, development has culminated in the multifrequency, multigeometry Geotech EMEX Systems. The advances in hardware technology have also been matched by advances in interpretation techniques. Computer software has been developed to calculate resistivity and depth of conductors, allowing the production of contoured resistivity maps. Computer model fitting of the data allows us to determine conductor geometry, shape, and conductivity information that previously could only be gained with ground geophysical methods.

The low frequency of 190 Hz provided by the EMEX System allows penetration of the conductive overburden with sufficient energy to excite the conductors beneath, thereby ensuring detection of these difficult targets. Helicopter systems in general have a superior ability to penetrate conductive overburden since their configuration energizes only a small portion of the ground, which reduces the unwanted response from the overburden. The higher range of frequencies assures responses from resistive areas and fault locations with the EMEX Systems.

The compatibility of accurate radar positioning systems with the EMEX Series and high resolution data combine to provide a tool which eliminates the need for much of the ground follow-up work previously required. In many cases, expensive and time-consuming ground surveys can be totally eliminated by the use of the economical, fast helicopter methods.

Geotechr^i Geotech EMEX-1 Airborne

Electromagnetic System

EMEX-1 System Description

The Geotech EMEX-1 is the first airborne electromagnetic system to incorporate two pairs of coplanar coils and two pairs of coaxial coils. This configuration allows the operation of four frequencies simultaneously.

The basis for this configuration has been an in-depth study of the requirements for automated interpretation software. Geotech engineers decided that data from the earlier model Geotech-3 three frequency system was inadequate for this type of advanced analysis. It was also determined that even four standard frequencies would not be adequate for proper interpretation under ali geological environments. A completely flexible design was therefore incorporated, one that offered a choice of any four frequencies in the range of 190 Hz to 12 kHz.

There is no restriction as to selection of frequencies over this range, except for such technical considerations as harmonic relationships between frequencies. The Geotech EMEX-1 System is the only such system available. This flexibility has been made possible by the design of an electronic system, patent pending, which removes the interference between receiving coils in any multifrequency system without predisposing the system to base line drift. The frequencies may be operated to within ten percent of each other with no adverse effects.

Geotech should be consulted on the best choice of frequencies for each particular application. Complete contract services are also available from preliminary survey planning through to final data reduction.

Geotech Datacam Video Flight Path Recovery System

The Geotech Datacam video flight path recovery system complements the Datacam recorder system and is used to locate the flight path points recorded on the video cassette by means of the self-contained B&W CRT monitor. A single control knob selects all playback functions: high speed forward and reverse; slow motion forward and reverse; or single frame. Various forward and reverse speeds are provided to enable the operator to quickly locate the specific frame of interest. A separate push button advances the frames in still mode. Advanced circuitry produces a sharp screen image and eliminates virtually all noise and blur even on slow motion or still frames regardless of tape speed.

Operation of the Datacam recovery system is simplified by the use of an infra-red type remote control unit which duplicates all functions of the control knob. The remote control unit has a range of 6 m extending over an arc of 600 . An optional power unit adapts the recovery unit for operation from any power supply in use throughout the world.

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.

l^ INTRODUCTION

l This report describes the results of a combined airborne magnetic and

g electromagnetic survey, totalling 76 line miles, carried out for Jalna

™ Resources Limited over the Dawson Road Lots in northwestern Ontario,

l located approximately 5 km east of Shabagua, Ontario.

The survey area comprised 41 flight lines spaced 1/Sth mile apart, and

directed N 200 E over the entire area.

8 The electromagnetic detector coils mounted in a special frame or "bird"

were towed 100 feet below the helicopter. The average height above

l ground of the bird was 120 feet. The magnetometer-VLF bird was located

^ midway on the HEM tow cable, providing a sensor clearance of

™ approximately 160 feet. The purpose of the survey was to prospect for

l base-metal mineral deposits associated with gold mineralization. The

field work was carried out during January, 1985. Data processing,

interpretation and reporting were done in Toronto during the period

February- June, 1985.

•j This report was prepared for Jalna Resources Ltd. by Paterson, Grant Se

Watson Limited.

l— 2. DATA PRESENTATION

l 2.1 Electromagnetics

The Airborne Electromagnetic Survey Profiles show profiles of

l in-phase and quadrature EM response along all flight lines.

l

l

ll *l These profiles have been transcribed digitally from the analog

data, after removing a constant base level value.

m The Geophysical Interpretation Map is an interpretation map

which shows the inferred axes and strike directions of the

l significant conductors, together with the in-phase anomaly

amplitude in parts per million (ppm) of the primary field

l strength and the apparent conductances derived from the

m vertical half-plane model. The apparent conductance is

determined by applying the in-phase and quadrature anomaly

l amplitudes to the phasor diagram for the vertical half-plane

model, which is shown as an inset on the map. The

l relationship of apparent conductance to the true conductance,

m which in the case of narrow, slab-like bodies is the product

of the electrical conductivity and average thickness, depends

l upon how closely the body approximates the sheet-like form,

and upon how nearly at right angles its strike direction to

l the flight path of the aircraft. Also determined from the

m phasor curves but not shown on the Geophysical Interpretation

Maps are the apparent depths to the tops of the conductors,

l Although the phasor curves are often able to distinguish

between conditions of comparatively thick and thin overburden,

l

l

l

the depth estimates which they give are not generally

reliable. Some of the more common reasons for this are:

l l

(i) the conductivity of the body changes with the depth;

l (ii) the conductor plunges;

m ( iii) the dip is substantially less than vertical;

(iv) interference from conductive overburden or host-rock

l has distorted the anomalies; or

(v) the body has too short a strike length to give a good

l half-plane response

Any of the conditions enumerated above may affect the anomaly

l amplitudes. Some will cause roughly proportionate changes in

both phases, so that the depth estimates tend to be more

l seriously affected than the conductance estimates.

The conductance values are divided into groups and the symbols

l given in the Geophysical Interpretation Map indicate the range

into which each analysis falls. This procedure generally tends

l to make the work of diagnosis easier. Thus, most overburdens

m have apparent conductances which fall into the lowest range on

the scale (l 2 mhos), whereas conductive clay deposits may have

l apparent conductances in the next higher range (2-5 mhos).

Also included as a general rule in the two lowest ranges are

l

l

l

l

the very weak bedrock conductors, such as unmineralized faults

and shears.

ll

Ordinarily, the flat-lying surficial deposits are easily

l distinguished from these bedrock and structural features by the

—m shapes of their responses, and wherever this has been possible

they are identified on the map with the symbol S. The higher

l ranges in the scale of apparent conductances ( ^ 5 mhos )

indicate that a significant fraction of the electrical

l conduction is electronic rather than electrolytic in nature.

j Materials which conduct electronically are limited to the

™ metallic sulphides and to graphite. Thus, the higher apparent

l conductance categories are generally limited to graphite- and

to sulphide-bearing rocks.

lj The apparent conductance of a rock unit, in mhos, is very

B largely an indicator of its electrical properties. The value

l is affected to some extent by the strike length of the body (if

it is short), and by the dip; but these effects are

l comparatively minor, and are unlikely to cause more than a 301

— change. A strong conductance ( ^ 20 mhos) indicates

well-connected mineralization extending throughout a fairly

l large region, and this usually suggests either graphitic zones

or massive sulphides. Such features generally respond well to

f ground surveys using closely-coupled systems such as the

— horizontal loop method. Poor to moderate conductances (4 to 20

™ mhos) may originate from massive sulphides, if they are not

l

l

l

ll

well connected, or if they are of a poorly-conducting variety

l such as some forms of pyrite and galena. Greater care and more

m thoughtful planning are often needed to detect these bodies in

follow-up surveys on the ground.

lAppendix l provides a tabulation of anomaly amplitude (in ppm),

l apparent conductances (in mhos), and apparent depths of burial,

m for all significant EM conductors in the area. These

interpretations are also presented in the Geophysical

l Interpretation Map on a topographic base to permit direct

correlation with the available geology, and to assist in the

l ground follow-up program.

2.2 VLF Electromagnetics

l The Hertz Totem 2A airborne VLF electromagnetic system was used

on the present survey. Two stations, Annapolis, Maryland (NSS)

l and Seattle, Washington (NLK) were recorded, using Cutler,

H Maine (NAA) as a substitute for NSS. The in-phase (total

field) and quadrature components for both the "line" and

l "ortho" frequencies were recorded in both analog and digital

form. The "line" information, either Annapolis or Cutler, were

l produced as contours of the total field and profiles of the

M quadrature response.

l

l

l

l

ll

Due to the high frequency { ~15 kHz) of the VLF electromagnetic

l signal, the method is capable of detecting bodies of small

•j dimensions and sources which may be described as partially

disseminated (i.e. not massive sulphide conductors). In

l addition, fault and/or shear zones, and alteration zones (or

halos) exhibit a strong response using the VLF method.

m The major disadvantage of the VLF method is also a direct

result of operating in the "high" frequency or radio range.

l Shallow zones of poor to moderate conductivity will exhibit

strong VLF responses. These spurious features often correlate

with changes in the depth of conductive overburden or with

conductive topographic features.

l 2.3 Magnetics

The Total Field Magnetic Map shows contours of the total

l magnetic field, uncorrected for regional variation. Whether

m an EM anomaly with a magnetic correlation is more likely to be

caused by a sulphide deposit than one without depends on the

l type of mineralization. An apparent coincidence between an EM

and a magnetic anomaly may be caused by a conductor which is

l also magnetic, or by a conductor which lies in close proximity

m to a magnetic body. The majority of conductors which are also

magnetic are sulphides containing pyrrhotite and/or magnetite.

l

l

l

- 7 -l l

Conductive and magnetic bodies in close association can be -

l and often are - graphite and magnetite. It is often very

m difficult to distinguish between these cases. If the conductor

is also magnetic, it will usually produce an EM anomaly whose

l general pattern resembles that of the magnetics. If the

conductor is strongly magnetic, the amplitude of the in-phase

l

l

l

l

l

l

EM anomaly will be weakened; and if the conductivity is also

weak, the in-phase EM anomaly may even be reversed in sign.

3. GEOLOGY

The region is underlain by a complex of Archean undifferentiated

metavolcanics and metasediments. Along the northern boundary of

the Dawson Road Lots survey area the present geological mappingm

indicates a change to a predominately metasedimentary suite of

l arkose, conglomerate and greywacke.

l

l

Immediately northeast of the present study area, diabase dikes

and/or sills have been mapped and extensive northwest-southeast

striking iron formations have been mapped south of the area. The

l present aeromagnetic map indicates that similar feature (i.e.

diabase, iron formation) may be present, south of the highway

within the survey area.

l l lflj To date, two gold occurrences have been discovered at the western

end of the survey area, south of the highway, and are located

l the within metavolcanic-metasedimentary sequence. Copper-zinc

•j mineralization has been noted to the north of survey area and is

associated with the regional diabase sill/dike complex.

l4 . INTERPRETATION

lm 4 .1 Magnetic Data

The total magnetic field contour map over the Dawson Road Lots

l is dominated by two magnetic patterns; a disrupted, linear 200

nanotesla (nT) anomaly striking ESE-WNW across the map, north

l of the highway and a complex of strike limited, 400 to 600

M nT, anomalies south of the highway.

l The northern pattern correlates with the buried boundary of

the metavolcanics. Along the northern edge of the survey area,

l the magnetic pattern becomes more subdued, reflecting the

M underlying weakly magnetic metasediments. The area south of

™ the highway is dominated by a severely disrupted positive

l magnetic feature that correlates with either an intrusive

gabbro or iron-rich metavolcanics. North of the transmission

l line the gabbroic signature is replaced by a more

— linear -to-lenticular anomaly pattern that correlates with

™ the metavolcanic-metasedimentary suite.

l

ll

The disruption of the magnetic patterns, as noted previously,

l is evidence of two major fault/shear trends in the area. An

j ESE-WNW trend strikes subparallel to the lithology and has been

— interpreted from the eastern edge of the area extending west to

l Line 13. The second more evident trend varies in direction

from N-S to NE-SW and disrupts both the lithology and the

l earlier ESE-WNW trend.

4.2 Electromagnetic Data

l The electromagnetic (HEM) conductors detected on the Dawson

Road Lots may be separated into two possible classes. The

l first class exhibits good line-to-line correlation and extends

— across many flight lines. In general, this class of conductors

parallels, or is coincident with, a good VLF conductor and

l correlates with a lithologic unit within the metavolcanic-

metasedimentary suite (e.g. Target A). The second class of

g conductors possesses a more limited strike extent (four flight

— lines or less), may or may not correlate with a VLF conductor,

™ and dos not correlate with regional formational trends (e.g.

l

—

l

l

l

Target B).

Two major class one, or formational conductive zones have been

detected on the Dawson Road Lots. The first zone (Target A)

- 10 -l l

lies immediately south of the highway, extending from Line 15

g to Line 26. The second zone strikes WNW-ESE along the southern

— edge of the survey area and crosses into the Jalna Resources

" property between Lines 9 and 17. Two zones of class two or

U discrete, non-formational, conductors have been detected south

of the transmission line. The first suite of discrete

l anomalies lies south of the Jalna property, between Lines 6 and

— 10, the second zone lies within the claim block, crossing Lines

B 15 and 16 (Target B).

l Three target areas have been selected for further work and will

be discussed below in detail:

lTarget A; Located on the northern edge of the metavolcanic

" suite, immediately south of the highway. As noted previously,

—j the conductor probably correlates with a single metavolcanic

unit. The strongest portion of the conductor lies between

l Lines 21 and 23, near the junction of major WNW-ESE and NNE-SSW

faults. Calculated depths indicate overburden and metasediment

lcover of 250 feet or greater in the area of highest

conductance.

l Target B; This discrete, two line conductor (Lines 15 and 16)

is located along the southern edge of strongly magnetic

m gabbroic intrusive. The zone exhibits relatively weak

l

l

l

l l

conductivity and an increasing depth of burial from west to

" east. The zone is terminated on the western end by a major

M NNE-SSW shear zone.

l Target C; The portion of the southern formational conductor

that crosses into the Jalna Resources claim block has been

™ denoted as Target C. On Lines 10 and 11, the conductive zone

m possesses poor to moderate conductivity (2 to 5 mhos) and a

depth of burial of approximately 100 feet. Both the magnetic

l and VLF interpretations indicate disruption of the conductive

zone by NNE-SSW shearing.

M 5. RECOMMENDATIONS

As a result of the geophysical interpretation of the HEM, VLF-EM

l and aeromagnetics on the Dawson Road Lots the following tasks

should be undertaken as part of a continuing exploration strategy

m for sulphide-related gold mineralization.

Task l:

l Processing of the total field aeromagnetics to produce colour and

contour plots of the first vertical derivative and apparent

m magnetic susceptibility. These maps will prove invaluable for

•j interpreting the underlying volcanic sedimentary sequences, for

delineating fault structures and for isolating granite/gabbroic

l

l

l

lll l

- 12 -

l

l

intrusives. The correlation of the detailed interpretation of the

processed magnetics with the HEM and VLF-EM will provide a stronger

link between ore deposition and possible structural/lithological

l controls.

Task 2;

Targets A, B and C should be followed-up on the ground using the

following techniques:

l i) Detailed geological mapping and geochemical sampling.

l ii) Ground VLF and magnetics on a 100 metre grid, with a

m station spacing of 25 m.

l iii) Induced polarization surveys of all three targets on the

same grid as the VLF-magnetics.

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 Land Management Branch, Toronto. The report will be re-assessed and a new statement of credits based on actual days worked will be issued.
