REPORT ON THE COMBINED AIRBORNE GEOPHYSICAL SURVEY

ON THE PROPERTY OF MR. W. MCCHRISTIE

MOSS TOWNSHIP AND BURCHELL LAKE AREA, ONTARIO

I INTRODUCTION -

Between January 27th and 33th, 1988 a combined airborne

geophysical survey was completed on the property of Mr. Kayne

McChristie in Moss Township and Burchell Lake Area, Ontario.

Magnetic and VLF-e]ectromagnetic data was collected by the

airborne Division of H. Ferderber Geophysics Ltd. The survey was

flown from a base at Thunder Bay, Ontario. A total of 149.9

miles of data was collected.

The magnetic survey provides information which helps define

the underlying geological structures and identifies any potential

economic concentrations which may contain variations in accessory

magnetic minerals. The VLF-electromagnetic survey outlines

conductive zones which may represent shear zones and/or metallic

sulphide deposits containing gold mineralization.

PROPRRTY DESCRIPTION, ^OgATION AND^ ACCESS

The McChristie Property is composed of two blocks of claims

covering approximately 1232 hectares in Moss Township and the

Burchell Lake Area, Thunder Bay Mining Division, Ontario. Sixty-

two claims are located in the northeastern part of Moss Township

and the northwestern part of the Burchell Lake Area, directly

north of Highway 802. The second block of fifteen mining claims

is located in the northeastern part of Moss Township, and

directly south of Highway 802. The claims are registered with

the Office of the Mining Recorder at Thunder Bay, Ontario, and

are listed in Appendix 1.

The property is situated three miles west and south of the

town of Burchell Lake, and approximately sixty-four miles west of

the city of Thunder Bay. Highway 802 separates the two claim

blocks of the McChristie Property in a northeasterly direction.

The smaller group of claims lie over a small nameless lake, and

both claim blocks contain small rivers and creeks which join Moss

Lake and Rainbow Lake in the south to Burchell Lake in the

northeast. The property is forested and topographic relief

appears to be moderate.

Supplies, services and manpower are readily available in the

Thunder Bay - Fort Francis area.

GEOLOGY

The Ontario Department of Mines, Geological Compilation

m Series, Atikokan-Lakehead Sheet, Map 2065, outlines the geology

underlying the property. A unit of undifferentiated

I metavolcanics with some metasediments strike northeastward,l BP

'. through the southern and eastern parts of the northern claim

j l block and may underlie the extreme northwestern corner thetm southern group. Acid metavolcanics (rhyolite and trachyte) arel

thought to be situated under the eastern third of the south

l group. Two bodies of acid igneous and metamorphic rocks underlie

the western two thirds of the southern claim block and intrude

the metavolcanics in the northeastern corner of the north group.

I The undifferentiated metavolcanics, underlying the north block,

are in contact with metasedimentary rocks (arkose, greywacke,

slate, mica schists and gneisses). A major fault, subparallel to

the Knife Lake Fault, cuts both claim groups in a north-

northeasterly direction.

One past producer, the Kerry Mine, is located in the

central part of Moss Township, approximately two miles south of

the McChristie Property. Pre-Kenoran mafic to intermediate

metavolcanics are cut by a northeast-trending feldspar dyke and

l

l l

li i i i im

an auriferous quartz vein, both traced over 3,000 feet. Gold

assays were erratic, the highest was 4.66 ounces from a 9 inch

wide vein section. Recovery of gold averaged 0.21 oz/ton of ore

milled. Between 1932 and 1942, 29,948 ounces of gold, and

172,375 ounces of silver were recovered.

The only other gold occurrence within Moss Township is

located 6-8 miles southwest of the McChristie Property. The

Lobanor Prospect is located east of Moss Lake and 400 feet north

of Snodgrass Lake. Pre-Kenoran felsic to intermediate

metavolcanics enclose mafic intrusives and three east-striking

mineralized zones. The South Zone is 1,100 feet long and

averaged from 0.06 oz An/ton over 13.9 feet to 0.16 Oz Au/ton

over 17.5 feet. The Middle Zone gave erratic gold values. The

North Zone returned two values 0.27 oz Au/ton over 1.0 feet, and

0.24 feet oz Au/ton over 2.5 feet.

Directly east of the large claim block are two copper

occurrences, on the western shores of Burchell Lake.

SlJRVEYMETiODS

The survey was completed using a 1 972 Cessna 172,

fixed-wing aircraft, call letters CF-EWK, owned and operated by

H. Ferderber Geophysics Ltd. The pilot and navigator/operator

were Y. Saucier and D. Thai, respectively, of Val d'Or.

Geophysical sensors were mounted in modified wing tips.

The geophysical, navigation and data acquisition systems are

described below.

Magnetometer

The magnetometer used was GEM Systems GSM-11, high

sensitivity airborne proton (Overhauser) magnetometer. The

instrument continuously measures the Earth's magnetic field at a

0.01 gamma sensitivity for l reading per second or 0.05 gamma to

10 readings per second at a 0.1 gamma absolute accuracy. The

analog output is on 3 channels, from l to 10,000 gammas full

scale.

l

VLF-EM System

l ~lIB A Herz Totem 2A VLF-EM System was used to measure the

m changes in the total field and in the vertical quadrature field

on two frequencies simultaneously, with an accuracy of J-%. The

l primary transmitting station of Seattle, Washington, (NLK),

frequency 24.8 KHz was employed in survey.

Radar Altimeter

B The ground clearance was measured with a King 10/10 A

radar altimeter. The survey was flown at a mean clearance of 300

m feet with the altimeter producing an accuracy of 5*^ (15 feet) atir

a this altitude.

Tracking Camera and Video Centre

A RCA TC-200 colour video camera and Galaxy 200 video

centre was used to record the flight path on standard VHS type

video tapes. Manual fiducial s were indicated on the picture

-7-

l frames for reference with digital printout. Flight path recovery

was aided using a Panasonic Colour Video Monitor-81300 and Video

l Cassette Recorder AG-2500.

l Dart a Acgu^isitaon ^System

lA Picodas Group Inc. PDAS 1100 data acquisition system

: | featuring seven analog inputs with two frequency inputs and

m external interfacing was used. A Termiflex Corp. ST/32 Keyboard

control unit and Sharp Corp. LCD display unit are connected to

l the data acquisition system. At present this system stores the

altimeter VLF-1 inphase, VLF-1 quadrature, VLF-2 inphase, VLF-2

l quadrature, magnetic field (coarse), magnetic field (fine), and

m the fourth difference (noise), and fiducials on 3.5 inch floppy

disk drive. The data is then printed out in digital and profile

l form.

The survey was conducted on northwest-southeast lines

l were flown at spacings of 328 feet at a speed of approximately 90

miles per hour. Navigation was visual using airphoto mosaics, at

a scale of one inch to 1320 feet, manual fiducials and the flight

path recovery system as references.

DATA PRESENTATION

Flight lines, fiducial points and geophysical responses

were reproduced from the airphoto mosaics at a scale of one inch

to 1320 feet (1:15,840). The outline of the claim blocks and

claim map are shown on each map sheet.

The aeromagnetic data was corrected for diurnal

variations by using a base line as reference. The data was then

reduced to a base level of 60,000 gammas, contoured at 25, 100,

and 1000 gamma intervals and presented on Maps MG-1.

A base value was determined for the VLF-EM data and the

change in the total field strength as a percentage of the base

value was calculated. The values were plotted on Maps EM-1 and

EM-2. The positive values were contoured at intervals of 2%.

The conductor axes were determined and labelled l, 2, 3, etc. No

priority was attached to the labelling system.

SURVEY RESULTS AND INTERPRETATION

Magnetic Survey

A prominent moderate to high anomalous zone covers both the

north and south claim blocks, exhibiting values ranging from 500

to more than 1000 gammas above background. This zone forms a

band of highs and lows striking northeasterly through both claim

blocks. The southwestern half of the band contains three

northeasterly striking highs, whereas the northeastern half of

the band contains a number of small discontinuous northeasterly

highs.

North Claim Block

Within the northeastern claims of the north block, there are

a series of discontinuous moderate anomalies in the range of 600

gammas above background which probably correspond to presumed

metasediment beds interlayered within the metavolcanics.

Along the northern boundary, an anomalously low magnetic

area, with values less than 400 gammas is situated over the

presumed beds of metasediments.

l

l

-10-

In the centre part and along the southern boundary of the

north block, the magnetic values increase noticeably to form a

prominent magnetic high located between the two claim blocks.

The shoulder of this high has a steep gradient and mag values

range from 600 - 800 gammas above background. This zone roughly

coincides with the presumed contact of the metasediments to the

north, and the band of metavolcanics, striking in a northeasterly

direction between the two claim blocks.

Located between the north and south claim blocks in the

west, is a strong magnetic high with values up to and in excess

of 1200 gammas above background. This high probably corresponds

to the northeasterly striking metavolcanic band located between

the claim blocks. The southern shoulder of this high magnetic

anomaly is very steep and coincides with the presumed

northeasterly striking fault.

South Claim Block

Along the northwestern boundary of the south claim block is

a moderate north-northeasterly striking trough anomaly which it

thought to overlie to a granitic unit. Values range from 700 to

800 gammas above background.

l

l

l

-11-

Within the northern section of the south claim block is a

very strong magnetic anomaly, with values up to and in excess of

l 1000 gammas . above background. This high corresponds to the

presumed location of the contact between the acid raetavolcanics

l to the south and the granitic unit to the north.

M Similarly in the southwestern section of the south claim

block, another strong magnetic anomaly with values up to and in

l excess of 800 gammas above background is located along the

presumed contact between the acid metavolcanics, to the south,

and the granite unit, to the north.

j Along the eastern boundary of the south claim block, the

1 shoulder of the central magnetic high has magnetic values ranging

l between 500 and 700 gammas above background. The location of,'si

-^ this magnetic gradient lies near the acid metavolcanic unit

situated to the south. The rhyolitic unit which extends in a

\m northeasterly direction north from Moss Lake may contain

-j accessory magnetic minerals which results in the moderate

fi magnetic signature.

i

l'l VLF-Electromagnetic Surveyi

I The airborne VLF-electromagnetic survey was successful in

outlining fourteen conductors. Conductors 1-8 in the north block

iii

-12-

and conductors 9-14 in the south claim block. All conductors

within the property strike approximately in a northwesterly

direction.

North Claim Block

M Conductor l is a short northwesterly trending conductor

located in the northeastern part of the north block. Its

mm position roughly overlies the location of the presumed

F.

northeasterly striking fault, and may represent a shear

m associated within the geological contact.

Conductors 2 and 3 are two short northwesterly conductors

which lie along the presumed contact between the northeasterly

l striking metasediments to the north and the metavolcanlcs to thelr. south.

lB Conductor 4 comprises two short northwest striking

conductors. Its position overlies the shores of a small lake,

- and it is probably the result of lake-shore effect.

1'

Conductor 5 is a very prominent, northwesterly striking;(!;, ! :

conductor located along the western boundary of the north claim

*B block. It lies within the presumed northeasterly striking

I metavolcanics band with minor metasediraents, and may be the

result of a shear.

Conductor 6 is a northwesterly striking conductor located in

the southwestern portion of the north claim block. It is roughly

located along the presumed geological contact between the

raetasediments to the north and the metavolcanics to the south,

and may represent a shear zone.

Conductor 7 is comprised of three short northwesterly

trending conductors located in the western part of the north

claim block. It overlies the northern shoulder of the magnetic

high, and it may be the result of a shear within the

metasediment/metavolcanic geological contact.

Conductor 8 is a northwesterly trending conductor located

within the presumed metavolcanic unit with some metasediments.

It overlies the south shoulder of a strong magnetic anomaly, and

its strength may be due to a shear zone.

South Claim Block

Conductor 9 is a short northwesterly striking conductor

l located in the northern part of the south claim block. It

overlies the shoulder of a strong magnetic anomaly, and lies

along the north shore of a small lake. Its location and strength

are probably the result of lake shore effect.

-14-

Conductors 10, 11 and 12 are three subparallel northwest to

north-westerly striking conductors all overlying a lake in the

south central part of the claim blockt All 3 conductors arei1

. probably caused by lake-shore effect.l Conductor 13 is a short northwesterly striking conductor

I located along the southern boundary of the south claim block. It

f overlies a very small pond and could be caused by changes in

topographic relief.,. if',-.

Conductor 14 is a strong northwesterly striking conductor

located along the southwestern boundary of the south claim block.it

~l It overlies a strong magnetic anomaly and also a small lake. It

iPl

i

ii

may be the result of a shear within the presumed north-

northeasterly trending fault or due to lake shore effect.

CONCLUSIONS AND RECOMMENDATION

The combined airborne magnetic and VLF-electromagnetic

M survey was successful in helping outline the underlying geology

" and in defining 14 conductive zones on or very near the

boundaries of the property of Mr. Wayne McChristie. The

-15-

m structural and lithologic complexity of the property as indicated

by the magnetic data suggests that the claims are located in a

l good geologic environment for gold and/or base metal

mineralization.

lm Further work is warranted on the property especially in the

•M areas of the possible bedrock conductors. An exploration programl

of ground geophysics and geological mapping should be completed.

A combined vertical gradient/total field magnetic survey and

horizontal loop electromagnetic should be performed, followed by

an induced polarization survey over selected conductors.j!

B Potentially interesting geological targets and geophysical

anomalies should then be tested by diamond drilling.
