INTRODUCTION

Ground magnetometer and HEM surveys were carried out in the Big Duck Lake, Bobbie Lake and Southeast grid areas between July 29 r 1 983 and September 5, 1983. These geophysical surveys were also performed on Big Duck Lake itself and the Shy Lake and Southpine Lake grids from January 2 to February 8, 1984 inclus ive. A total of 326 km of north-south picket and east-west base

lines were surveyed (Figure 1). The claim group is accessible in the summer using float-equipped fixed-wing aircraft and in the winter via snowmobile.

PREVIOUS WORK

The Big Duck Lake - Winston Lake area has been sporadical

ly explored by numerous companies for base and precious metals since 1888 when high-grade zinc was discovered at Kenabic Lake. This showing later became the Zenith Mine which produced 181,000 tons of 16.5% zinc between 1966 and 1970. In June 1982, CFC discovered the Winston Lake massive sulphide, zinc-rich ore body and this sparked intensive staking in the area by CFC, Noranda

and others.Hopkins (1915) and Bartley (1942) produced the first

geological maps of the area. However the most recent government map is by Pye (1964). In the assessment files there are geolog

ical, geophysical and geochemical surveys for parts of the area. Diamond drilling was also done on some of the gold showings in the Big Duck Lake area during the 1950's, 1960's and 1970's.

GEOLOGY

Corporation Falconbridge Copper has been mapping and re-interpreting the rock types exposed in the Big Duck Lake and Winston Lake areas since 1979. These surveys have been or will be filed for assessment work credit and consequently only a brief

summary of the geology will be presented here.The Big Duck Lake - Shy Lake area is underlain by a

homoclinal, north-facing sequence of mafic extrusive and intrus

ive rocks. In the Big Duck Lake area itself, numerous quartz-

feldspar porphyritic felsic sills intrude the mafic sequence. Many of the old gold showings in the region are intimately as sociated with these felsic intrusions. In the Shy Lake area, 2

regional, sulphide-bearing iron formations occur at the top of the mafic volcanic sequence.

RESULTS OF THE GEOPHYSICAL SURVEYS

The magnetic and HEM anomalies outlined by these geophys

ical surveys are discussed in the appended technical reports

prepared by Jim Walker of Walker Explorations. Copies of maps of the data are also included.

CONCLUSIONS

Several HEM conductors have been delineated by these

surveys. Most conductors have a high magnetic signature associ

ated with them. Although all conductors will be tested even

tually by diamond drill holes, those which will be initially tested must have corresponding interesting geology and anomalous

lithogeochemistry. Thus an evaluation of the geology and lithogeochemistry is required in order to select the HEM conduc tors which will have the best chance of being associated with economic mineralization.

INTRODUCTION

At the request of Dr. Gerald Riverin, Senior Exploration Geologist

for Corporation Falconbridge Copper, Walker Exploration Ltd. contracted to

carry out geophysical surveys over part of the large claim holdings of

Corporation Falconbridge Copper at Big Duck Lake. Linecutting and chaining

was carried out by another contractor.

The magnetic survey was carried out with an EDA PPM 300 proton

magnetometer, with solid state memory. Diurnal control was made using an

EDA PPM 400 base station recorder, also with memory. Both instruments were

synchronized in time, and when connected together each night, diurnal

corrections were made automatically.

The horizontal loop EM tests were made with an APEX PARAMETRICS

MaxMin II EM unit, using a coil spacing of 150 meters and frequencies of

888 Hz and 3555 Hz.

Field work was carried out during the period July 29th to

September 5th at Big Duck Lake and September 6th to 10th at Cleaver Lake

(testson small grids). A total of 190 kilometers was surveyed at Big Duck

Lake. Four small outside grids were also tested.

SUMMARY

The magnetic survey has located numerous narrow magnetic bends

which may be related to favourable veining containing gold with magnetite.

Several long conductors were located along the grid, which are likely

- 2 -

related to sulphide mineralization. Some are coincident with the magnetic

bands.

PROPERTY

The surveys were carried out over part of the large claim holdings of

Corporation Falconbridge Copper in the Winston Lake - Big Duck Lake area,

which are being explored for themselves and in joint venture with others.

Access to the Big Duck Lake Area is by aircraft from Pays

Big Duck Lake, which is about 20 km north of the town of Schreiber on

Highway 17.

PREVIOUS WORK

The area has had considerable exploration over the years, with

prospecting, geochem, geophysics and drilling over parts of the claims

surveyed. Numerous mineral occurrences have been located, including gold,

silver, copper, lead, zinc and molybdenum.

GEOLOGY

The claims surveyed are along an east-west trending belt of

Precambrian intermediate to mafic metavolcanics, with intrusions of

granitic rocks to the north of Big Duck Lake, and some ultramafic intrusion

in the northwest. A belt of meta volcanics occurs to the north of the

volcanic rocks.

Some of the gold occurs in magnetite rich veining adjacent to

" J "~

quartz feldspar porphyry dykes.

SURVEY METHODS

The magnetic survey was performed with an EDA PPM 300 proton

magnetometer. Diurnal control was with an EDA PPM 400 base station

recorder, synchornized in time, with the field magnetometer. As each

instrument has a solid state memory, corrections were made automatically

each evening for diurnal drift. As we also had a HP85 computer in the

field, we were also able to store corrected magnetic values on cassette

tape, and made a print out of values and profiles to scale each day for

presentation to the project geologist.

Readings were taken along lines 100 meters apart, at 12.5 meter

intervals. Values are plotted on base maps supplied by the company, and

then contoured.

The horizontal loop EM tests were made with an Apex Parametrics

MaxMin II unit, along the same grid. Coil spacing was 150 meters, and

frequencies read were 888 Hz and 3555 Hz. Conductor axes are shown on the

plans for the.3555 Hz frequency and details of conduction are listed in

appendix.

SURVEY RESULTS

The magnetic survey shows an east-west trend to formation. Parallel

to the trend are numerous narrow but generally long bands of magnetic

highs. Some faulting is suggested from the magnetic patterns.

The horizontal loop EM survey has located several long conductors

- 4 -

which are indicated on the plans. An evaluation of conductors is listed

in the Appendix. Some of the weak conductors (quadrature response) may

be due to contacts or shearing, On the "outside" small grids tested,pv.^

good conductivity, coincident with a magnetic high was seen on rone line at

Bobbie Lake.j ,~ .

No conudctors were located on the South

East Grid.

CONCLUSION

magnetic survey has located long narrow magnetic bands , which

may represent in some instances, the favourable veining adjacent to quartz

feldspar porphyry dykes containing magnetite and gold.

The EM conductors are in some instances coincident to the magnetic

bands. It is likely the conductors represent pyrite and pyrrhotite

mine rali zat ion .

Results of the geophysical surveys will have to be correlated to

the geological mapping of the company staff and the drilling of the old

showings on the claims.

COMMENTS

1. General

For the estimation of depth and conductance it was assumed that

the source of the anomalies are thin conductive sheets. In many cases, the

anomalies describe parallel conductors; although anomalies obtained over two

or more conductors must be studied as a whole, and cannot be interpreted solely

by means of a set of type curves derived for single conductors, useful estimates

can be obtained from these type curves neglecting the inductive interaction

effect.

2. Conductors ClA-1, ClB-1, ClC-1 and ClD-JL

This complex assemblage of conductors describe a wide geologic unit

hosting several parallel conductors. East of Sulphur Lake Conductor ClD-1

intends to indicate that there is a conductor further to the north and it .should

not be taken as an indication of a conductor axis. Somewhat more information is

available on Lines 1W and 2W where two conductors are suggested (ClC-1 and the

conductor to the south). Although the anomalies are incomplete, reasonably

good conductances (conductivity-thickness product) are hinted by the ratio of

the in-phase and quadrature components:.

The conductor picture becomes quite complex west of Sulphur Lake.

The anomaly along L-8W is not unlike the anomalies produced by wide conductive

bodies, but the anomaly on L-7W seem to indicate at least two narrow conductors,

which can be correlated with quadrature phase expressions on L-8W. Olie location

of the northernmost axis is uncertain. The anomalous responses on Lines 5W and

6W are markedly narrower than on Lines 7W and 8W, suggesting a narrowing of the

conductive sequence, but it should be remembered that the "wide" anomalous ;

sequence is open to the north. Conductor Ci A-1 which is reasonably expressed

on L-7W can be extended with some assurance to Line 6W but the extension further

to the east is dubious to say the least. If a simple conductor is assumed

along L-6W the estimations yield a conductance of about 2 mhos and a depth of

22 m.

3. Conductor C2-1

The conductive feature can be .traced from I/-22W to L-12W. This

conductor and its apparent eastern continuations. Conductors C3-1, C5-1, C2-1 and

C2-2 describe a conductive marker horizon.

The westernmost member, Conductor C2-1 generally portrays a poor

conductance feature, which pinches and swell along strike. The conductor is

nearly vertical but northerly dip is indicated along L-21W. Estimates along

L-12W "(assuming single conductor) give a conductance between 1-2 mhos and a

depth of about 20 m.

4- Conductor C3-1

This conductor extends from I/-9W to 4W. Further to the east the

survey is not completed but there are sufficient hints that an. extension of

C3-1 would join with C5-1. It is a poor quality conductor, quadrature phase

responses dominating. It improves along Lines 7W and BW. Estimates 'were carried

along L-8W (assuming a single conductor) giving a conductance of 2 mhos and a

depth of about 20 m.

5. Conductor C4-1

The relatively short strike length conductor south of C3-1 is a

poor quality feature having a conductance of less than l mho at an approximate

depth of 30 m.

6. Conductors CS-1, C2-1 and C2-2

.

marker horizon mentioned earlier. The conductance varies along strike, generally

about l mho, but the conductance is 3.0 mhos along L-8E. The depth of the

conductor is about 10 m at the western end and along Lines 14E and 15E. Eastward

from L-15E the depth increases to 22 m, 30 m and 40 m along Lines 16E, 17E and

18E respectively.

7. Conductor C3-2

The conductor exhibits a strike length of about 600 m. The quality

of the conductor deteriorates dramatically along the eastern and western ends.

The conductance is 2 mhos along L-33E, where the estimated depth is 40 m.

8. Conductor C4-2 and C5-2

The two nearly parallel conductors are the best quality features of

the survey. The depth estimations suggest that the conductors are at a depth*

less than 15 m. Of the two conductors the''southerly is the better quality

along which conductances in excess of 10 mhos were (L-36E and L-38E) were

estimated. The conductors appear to be vertical, but steep northerly dip is

intimated along the central part of C4-2 and southerly dip is suggesetd on

L-34E for C5-2.

9. Conductor -C6-2^

The quality of this relatively short strike length conductor

diminishes towards'the south. It is a shallow feature of conductance less

than l mho.

10. Conductors C3-1 and C3-2

C3-1 is the better conductor of the features. The depth of C3-1

is about 30 m and the estimated conductance is l mho. The anomaly over C3-2

is dominated by quadrature phase response. The poor quality conductor

(conductance: O mho) is at a depth of about 20 m.

COMMENTS

Bobbie Lake Grid

The only conductor of consequence is on L-16W. It is a short

strike length feature, which is not expressed on Lanes 15W and 17W. The

location of the conductor axis is no doubt because the anomaly shape is

distorted by the effects of the highly magnetic bodies in the vicinity of

the conductor.

South East Grid

There are no conductors of interest.

INTRODUCTION

At the request of Dr. Gerald Riverin, Senior Exploration Geologist

for Corporation Falconbridge Copper, Walker Exploration Ltd. contracted to

extend the geophysical coverage carried out during the summer of 1983 in the

Big Duck Lake Area. A grid was established on Big Duck Lake, and lines

extended to the north of the main grid. Linecutting and chaining was carried

out by Ben Nelson .of Jellicoe Ontario, and was of good quality. An outside

grid at South Pine Lake was also surveyed (about 3 km northeast).

The magnetic survey was again carried out with an EDA PPM 300 pro

ton magnetometer, and control was with a PPM 400 base station recorder.

The horizontal loop EM survey was made using an Apex Parametrics

MaxMin II EM unit. As in previous work coil spacing was 150 meters (except

200 meters over Big Duck Lake) and frequencies of 888 Hz and 3555 Hz.

Field work was carried out during the period January 2nd - February

8th, 1984.

SUMMARY

Weak conductive zones under Big Duck Lake are likely related to lake

bottom material. Considerable shearing, faulting and offsets of rock units

are suggested by the magnetic survey over the lake.

- 2 -

On the Big Duck Lake north extension (Sheet 5) a broad zone with

several parallel conductors occurs just north of Cable Lake, and extends

across the map from east to west. Another prominent conductor extends across

the map sheet to the north of Shy Lake.

Two weak to medium conductors occur on the South Pine Lake grid,

in part with magnetic coincidence.

PROPERTY

The property is located about 20 kilometers north of Screiber.

Access is by aircraft to Big Duck Lake. A rough trail exists between Big

Duck Lake and the old Zenmac mine, which our crew used for servicing. However,

it was not suitable for large loads on skidoo drawn sleighs, so camp move in

and out of Duck Lake was by helicopter (ice not suitable for large aircraft).

PREVIOUS WORK

The area has had considerable exploration over the years, with

prospecting, geochem, geophysics and drilling. Numerous mineral occurrences

have been located, including gold, silver, copper, lead, zinc and molybdenum.

GEOLOGY

The property is located along an east-west trending belt of Precam

brian intermediate to mafic metavolcanics and metasediments with basic and

acid intrusives. Granite occurs to the north and south of the belt.

Gold mineralization has been found in magnetite rich veining adjacent

- 3 -

to quartz feldspar porphyry dykes.

SURVEY METHODS

The magnetic survey was performed with an EDA PPM 300 proton

magnetometer. Diurnal drift control was with an EDA PPM 400 base station

recorder. Corrected values were stored on cassette of an HP 85 computer.

A print out of values and profiles to scale from the computer allowed for

editing and final plotting.

Readings were taken along lines 100 meters apart, at 12.5 meter

intervals. Values were added to previous maps covering Big Duck Lake and

the western grid extension (lines HW to 30W, O to 500 meters north) and

parts of Shy Lake and Sulphur Lake on Sheets l and 2. A new plan (Sheet 5)

was prepared for the grid extension beyond 10 North. A separate sheet was

also made for the South Pine Lake grid.

The horizontal loop EM tests were made with an Apex Parametrics

MaxMin li EM unit. Readings were taken along the same lines as the magnetometer

above, but station interval was 25 meters. Coil spacing was 150 meters (except

200 meters over Big Duck Lake). Conductor axes are shown on the plans for

the 3555 Hz frequency, and conductor details are listed in the appendix.

SURVEY RESULTS

Weak conductivity under Big Duck Lake is likely related to lake

bottom sediments. However the magnetic survey indicates complex structures

and is reported on by Consulting Geophysicist Frank Jagodits (see appendix).

- 4 -

The main feature on Sheet 5 (grid extension to the north) is a

broad band of parallel conduction across about 400 meters, going from east

to west, and is probably related to graphite and sulphides in metasediments.

The extension of this zone crosses the west end of the grid extension on

Sheel l from 22W to SOW.

To the north of Shy Lake, conductors 5-1 to 5-4 cross the map

sheet in a discontinuous zone of medium to good conductivity, in part with

magnetic coincidence. It is likely related to sulphide mineralization.

A band of very high magnetics crosses Sheet 5 from east to west,

just south of Shy Lake and causes "noise" in the EM survey, although no con- -

ductors are indicated along the zone.

On the South Pine Lake grid, about 3 km north, some magnetic

coincidence occurs along the north part of the grid. A weak to good conduc

tor is in the lake and along the north shore of South Pine Lake, in the

southwest part of the grid. A weak conductor is also indicated in the west

part of the lake, which is likely caused by lake bottom sediments.

Hie magnetics are presented with values and contours. The electro

magnetic survey is plotted with values and profiles, with a separate sheet

for each frequency.

CONCLUSIONS

The magnetic survey has shown a general east-west trend to structures,

Some cross faulting is indicated in Mr. F. L. Jagodits 1 interpretation of

results over Big Duck Lake. Several narrow magnetic bands which may represent

- 5 -

the favourable veining with magnetite and gold. Some of the EM conductors

share coincident magnetic highs, and probably represents pyrrhotite and pyrite

mineralization.

broad conductive area south of Shy Lake is likely caused by

graphitic horizon in metasediments, with some sulphides also present where

coincident with magnetic highs.

Many of the conductors are shallow and will likely outcrop, where

they could be located in mapping and prospecting. It is recommended that a

VLP EM unit be used to assist in field location of conductors , and to check

for the possibility of several conductors where wide zones are suggested by

the MaxMin survey.

It is also recommended that a full geophysical interpretation be

made using all geophysical and geological information available in order to

suggest the most favourable areas for gold mineralization.

COMMENTS ON THE HORIZONTAL LOOP EM (MAXMIN II)

AND MAGNETIC SURVEYS - BIG DUCK LAKE, ONTARIO

The following comments are related to the data obtained over Big

Duck. Lake during the winter of 1983-1984.

The horizontal loop em (MaxMin II) survey have outlined poor

quality anomalous features, the quadrature response generally being twice

that of the in-phase response. Two interpretations are possible: (a) some

of the anomalies are related to thinning and/or pinching-out of the conductive

lake bottom sediments and, (b) the anomalous responses are caused by thickening

conductive lake bottom sediments, electrolytic conductors.

The anomalies south of the islands in the centre of Big Duck Lake

are good examples of Case (a). At this locality the width of the anomalies are

considerably smaller than the coil separation used. Model experiments indicate that tha|

approximate location of the edge of the bedrock high may be found by measuring

half-coil spacing from the centre of the negative anomaly towards the central

positive peak. To the north of the islands the "anomalous" negative responses

have widths equalling or larger than the coil separation. It is suggested that

both causes (rising bedrock as well as "electrolytic conductor) come into play

here.

The location of the edges of the bedrock highs shown on the inter

pretation overlay should only be taken as approximations because in numerous

cases it is difficult to determine the exact location of the negative peaks.

In addition to the areas of thin or no lake bottom sediment cover,

three poor conductors believed to represent electrolytic conductors are outlined.

EXGAblBUR INTERNATIONAL CONSULTANTS LTD.

- 2 -

Of these Conductor C3 is within the northwest striking arm of the lake in

the southwest quadrant of the interpretation overlay. The arm is the locale of

a northwest striking fault and/or shear zone noted on the geologic maps.

The interpretation of the magnetic contour map was restricted to

the area covered by Big Duck Lake and to the immediate area surrounding it.

The main purpose of the interpretation was to delineate structural features.

The anomalies under the lake exhibit lower amplitude and wider widths showing

the effect of the increased distance between the magnetic sources and the plane

of observation. However it should be kept in mind that the decrease of the

amplitude of the anomalies may also be caused by decreasing magnetite content.

The fall-off rates of anomaly amplitudes vary depending on the geologic models

and are illustrated on the Figure 35 taken from "Applications Manual for

Portable Magnetometers" by Sheldon Breiner (GeoMetrics).

The magnetic results are dominated by nearly east-west striking

anomalies, believed to indicate intermediate to basic and basic composition

volcanics. The magnetic contour map to which additional 100 gamma contours

were added in areas of gentle gradients reveals complex structural deformation.

Two major directions of shearing and/or faulting are interpreted. The north

west, north-northwest strike of the first set is in accord with the known

strikes of structural deformation (ODM Map 2232) .

One of the major faults of the geologic map is within the northwest

striking arm of the lake as mentioned earlier. The magnetic data suggest that

there may be two parallel faults bordering the arm. The other known, northwest

striking fault is in the northeast tip of Big Duck Lake. The fault (or shear

zone) is expressed by the termination of the magnetic bodies. The second set

of shear zones strike northeast and north-northeast, terminating the magnetic

sequence located along the north central shore of the lake. Another major

BXGALIBUR INTERNATIONAb CONSULTANTS LTD.

- 3 -

northeast striking shear appears to terminate the most magnetic anomalous

bodies just south of the islands.

Two east-west strike faults are tentatively identified associated

with the above mentioned magnetic sequence, south of the islands. The northern

one of the two can be traced towards the west from L-18E.

The magnetic interpretation was carried out without background

geologic information, and would obviously benefit from incorporating known

geologic data. Furthermore it is suggested that the bathymetric map of Big

Duck Lake should be correlated with the interpretation seeking confirmation

for the structures interpreted and for the bedrock highs suggested by the

horizontal loop em survey.

COMMENTS ON CONDUCTORS

Sheet 5

Conductor 5-1

This conductor extends from 5W to 7E (1200 meters). Depth is

about 3 to 7 meters. Dip is steep to the south. Width varies from a few

meters at the east end to about 22 meters at 1W, O and IE. Conductivity

is strong, becoming weaker at the east end. Conductivity thickness pro

duct is about 25 mhos reducing to 10 mhos on line 6E. The conductor has

some local magnetic coincidence, or is adjacent to a magnetic high.

Conductor 5-2

This conductor (as well as 5-3 and 5-4) appears to be an offset

of 5-1. Depth is greater at about 15 meters. Conductivity thickness is

about 15. The influence of 5-1 and 5-3 make dip estimate difficult, but

is likely steep south. Width is likely less than 5 meters.

Conductor 5-3

Depth of zone is 8 to 12 meters. Conductivity is good at about

20 mhos conductivity thickness. Width is about 10 meters. A short parallel

conductor is also present. Dip is steep to the south.

Conductor 5-4

Depth is 10 to 15 meters. Conductivity is good at about 15 to 20

mhos conductivity thickness. Width is about 10 meters and dip steep to the

east. There is some magnetic coincidence with this portion of the conductor.

- 9 -

Shy Lake

Quadrature response likely due to lake bottom - not a bedrock

conductor.

Iron Formation?

A highly magnetic zone about 30 meters wide crosses the map sheet

just south of Shy Lake. There is some quadrature response and most lines

have positive in-phase peaks about h coil spacing (75 meters) from magnetic

high.

Conductor 5-5

Depth is about 30 meters. Conductivity is medium, conductivity

thickness about 8 to 10 mhos. Width is about 5 meters. Dip is not readily

apparent, due to response from iron formation to the north. The zone appears

to be adjacent to a narrow magnetic unit.

Conductor 5-6

Depth is 25 to 30 meters. 8 to 12 mhos is the conductivity thickness

product. Width is less than 5..meters. Dip is to the south (steep). The

zone is associated with a narrow magnetic unit. There is an offset to the

conductor on the east (line lw).

Conductor 5-7

Under the lake, lines 9W and 10W, the conductor has a depth of

30 to 35 meters, while to the east depth is only 5 to 10 meters (zone offset

to the east). Conductivity is good.

- 10 -

Conductors 5-8 to 5-14

These conductors appear to be related to a lithologic unit about

400 meters wide, likely graphitic metasediments. Ohey cross the lower

part of map Sheet 5 and continue across the north part of Sheet l (CIA-1,

CIB-1, CIC-1 and CID-1). Conductivity is usually good, and depth shallow.

Ihe conductors are sometimes associated with slightly magnetic units, and

are generally parallel to the east west magnetic pattern.

Conductor 5-8

This zone is about 1600 meters long, varying in width from 10 to

30 meters. Depth is less than 5 meters. Dip appears steep to the north.

Conductivity is good with conductivity thickness about 30 to 50 mhos.

Conductor 5-9

This zone is probably an offset continuation of 5-8 above, but

narrow in width. Conductivity is good and depth shallow.

Conductor 5-10

Depth of this zone is generally about 5 meters and up to 15 meters

at the east end (line 2E). Conductivity thickness product is 30 to 50 mhos.

Width appears about 5 meters. Dip is likely close to vertical.

Conductor 5-11

Depth of this conductor is again very shallow and conductivity is

good.

Conductor 5-12

Ihis shorter zone is indicated as a possible location of a separate

conductor, over the broad conductive area.

- 11 -

Conductor 5-13

Depth of zone is less than 5 meters over most of the zone, which

extends over 1500 meters on Sheet 5, and continues on Sheet l (C1A-1).

Unfortunately, the picket lines on the original grid and grid extension did

not line up to allow proper coverage on this conductor. The proper procedure

would have been to extend new lines about 200 meters onto old grid, where new

lines did not line up with old lines.

Conductivity is good, with conductivity thickness greater than

50 mhos. Width is not easily determined because of adjacent zones, but is

likely about 5 meters.

Conductor 5-14

This long conductive zone is generally shallow (Smeters) except at

the east end (Lines 15E fi 17E) where depth is about 45 meters. Conductivity

is also good with conductivity-thickness values about 50 mhos.

Sheet l

Conductors ClA-1, ClB-1, ClC-1, ClD-1.

Ohese zones are a continuation of the above group of conductors.

See F. L. Jagodits' comments - Report Dec. 5, 1984.

CI R-1

l*he survey was extended on Lines 9W s, 10W at the bottom end of

Shy Lake, and the conductor shows the same response of a broad conductor or

several parallel zones.

- 12 -

ClB-1

Lines were extended across Sulphur Lake and show that this conductor

likely joins ClC-1 along strike to the east. Depth is about 15 to 20 meters.

Conductivity is good.

ClC-1

This zone becomes shallower to the east (5 meters or less) and is

made up of several parallel zones on Lines lw and O, with good conductivity.

ClD-1

This zone is an offset continuation of ClC-1 to the west, and also

5-14 zone and Sheet 5 to the east. Depth is shallow and conductivity is good.

Because of the way the new and old grids join, there is not complete coverage

across the zone.


These zones at the west end of Sheet l are the extension of the broad

zone of parallel conductors (5-8 to 5-14, and ClA-1 to ClD-1). The zone crosses

the new grid extension (0-5N) at Line 21W.


These are under shallow cover (0-5 meters). Conductivity is good,

even under the lake, part of 1-1. Width is likely narrow, which is probably

steep.


Line 28W was extended about 375 meters beyond 5N, by walking through

bush. Data would tehrefore not be too reliable. However, at least 3 conductors

are indicated. Conductivity is good, and depths range from 37 meters at 1-5

zone to 5 meters at 1-7 zone.

- 13 -

South Pine Sheet

Conductor SP-1

This zone has a depth of 5 to 10 meters. Dip is steep to the

south. Conductivity is medium to good with conductivity-thickness about

10 to 25 mhos. Width is about 10 meters. There is also some magnetic

coincidence along the zone.

Conductor SP-2

Depth to conduction is shallow, 0-5 meters. Conductivity is

medium to weak, with conductivity-thickness about 10 and width is about 5

meters. The zone occurs along a complex magnetic pattern. Dip is steep to

the south.

SP-3

This short zone is located along the north shore of South Pine

Lake. Depth is about 20 to 25 meters. Conductivity is good, with conductivity-

thickness about 20. Width is about 5 meters.

SP-4

Depth is about 15-25 meters. Conductivity-thickness is about 20

on Line 7W and 50 on Line 6W. Width is about 10 meters. Dip is steep to

the south.

SP-S

Weak conductivity on Lines 7W to HW. Under the lake is probably

a response from lake bottom sediments.
