SUMMARY AND CONCLUSIONS

Iholeiitic rhyolite occurs near the core of an easterly

trending syncline whose axis passes through the central

Clergue 14 property. The rhyolite is underlain by altered

sulphidic pillowed tholeiitic andesite. Horizontal loop

electromagnetic anomalies C and F occur near the

rhyolitic-andesite contact. Two previous drill holes aimed

at anomaly C were stopped in strongly chloritized andesite

containing pyrrhotite-pyrite rich selvages. One previous

drill hole tested anomaly F at shallow depth (approx. 18

m). Anomaly F remains open at depth and anomaly G to the

south of F remains untested.

RECOMMENDATIONS

A total of 900 metres of drilling are recommended. (Two

holes) (Table 1).

Hole #1 (500 metres) will test EM anomaly F at 100

metres vertical depth and anomaly G at about 230 metres

vertical depth. The hole will test the upper and lower

contacts of the tholeiitic rhyolite (Figures 1,2).

Hole #2 (400 metres) will test EM anomaly C at about 120

metres vertical depth and will also test the upper and lower

contacts of the tholeiitic rhyolite 1.1 kilometres west of

proposed hole #1 (Figures 2,3).

INTRODUCTION

This is a geological report on 16 mining claims held by

Kidd Creek Mines in Clergue Township. The claims were mapped

at a scale of 1:5000 during the 1985 and 1986 field seasons.

The claims were recorded on January 9th 1984. The claim

numbers are as follows:

P - 731907

to Shillington, then north on highway 577 for 12 km to

highway 11. The Clergue Township Concession 1,2 road called

the Biglow Road occurs about l km northwest along highway 11

and leads into the central property area (Figure 4).

Topography over the property is generally flat to gently

rolling with greatest reliefs of 15-20 m at the edges of

outcrops. Outcrop areas have sparse jackpines while lower

areas are predominantly birch and poplar with minor balsam.

PREVIOUS WORK

The earliest recorded work included geological mapping

by J. Satterly (1953), D. P. Rogers (1957) and S. A.

Ferguson (1959) which was compiled at a scale of l inch to

1/4 mile and constitutes the Ontario Department of Mines

Clergue Township Map.

Texas Gulf Sulphur Co. conducted geological and

geophysical surveys over the property in 1960. Drill hole

C15-1 (64 m) intersected pillowed dacite from 22.5 to 50.3 m

with pyrrhotitic selvages which corresponds with EM

conductor F (Figure 5).

Canadian Aero Surveys carried out an airborne

geophysical survey for Alexo Extension Mines Ltd. in 1964

and suggested that further study of the property was

warranted.

David Weston drilled one hole of 43 m in 1968. It is

located at the northern edge of an outcrop of pillowed mafic

flows and massive flow banded rhyolite (Figure 5). The hole

intersected 37 m {true thickness) of chloritized andesite

with the intensity of chloritization increasing downhole.

Repeating veins of massive sulphides consisting of pyrite

and pyrrhotite with minor chalcopyrite on pyrite grain

borders were intersected from 37 to 43 m. This sulphide

section corresponds with EM anomaly C (Figure 5). Sulphides

comprised 301 of the core over the last 9 m of the hole.

A detailed ground geophysical study of the area was

conducted by Shield Geophysics for Amax Exploration Inc. in

1969. This work led to the drilling of hole KX-63-70 in

1970. This hole had a true depth of 79 m. It intersected

48 m (true thickness) of pillowed andesite containing S-95%

pyrite-pyrrhotite in pillow selvages. This hole appears to

have tested EM anomaly C. From 48 m to 79 m the andesites

became more intensely chloritized.

In 1984 Kidd Creek Mines Ltd. mapped the Clergue 14

property at a scale of l inch to 1/4 mile as part of a

regional study that included the south halves of Dundonald

and Clergue Townships.

In 1985/86 Kidd Creek Mines Ltd. conducted magnetometer,

horizontal loop electromagnetic (HLEM) and VLF surveys over

the property. Five weak to moderate HEM anomalies were

located (A,B,C,F,G). The property geology was mapped at a

scale of 1:5000.

REGIONAL GEOLOGY

The general geology of the area is shown at 1:50,000

(Figure 6). The area is underlain by Archean tholeiitic

mafic, felsic and komatiitic flows and intrusions with

primitive felsic tuffs and metasediment^. These rocks have

been folded into an anticline flanked by two east

northeasterly striking synclines which plunge to the west.

In western Clergue and southern Dundonald Townships these

rocks have been intruded by a differentiated sill of

ultramafic and gabbroic rocks called the Dundonald Sill.

North trending diabase dykes of the Matachewan Swarm are

common in eastern Clergue Township (Pattison 1984).

PROPERTY GEOLOGY

A synclinal axis passes through the central Clergue 14

claim block trending about 80 0 .

North limb stratigraphy commences with tholeiitic felsic

volcanics. This suite of rocks is uncommon but well

developed in the Abitibi Greenstone Belt. They have high

Y,Zr,Si02, total REE and low Sr and A12O3. They are host

rocks of the Kidd Creek, Kamiskotia, Noranda, Mattagami, and

Uchi Lake massive sulphide deposits. On Clergue 14 they are

best exposed between lines 8 and 16 west at about 8 south

(Figure 5). They are truncated to the west by a mafic

intrusion but are continuous to the east across the

property. They have a total minimum thickness of about 90

metres. These rocks have variable colour from a pale grey

off-white where unaltered or silicified, to pale to medium

green where weakly to moderately chloritized. Flow banding

is well developed throughout. {For a more detailed

description of the rhyolite see unpublished University of

Western Ontario BSc thesis by M. Kirwin 1985). The rhyolite

is underlain by a conformable gabbroic sill. Contacts with

the volcanics are sharp. The gabbro, measuring 20-100 m

thick, is massive, medium grained and dips steeply north.

Weathered surfaces are rusty grey-brown while fresh

surfaces are uniform grey green with occasional 2 mm

chlorite clots. Trace disseminated pyrite and pyrrhotite

occur throughout.

Underlying the gabbro is about 250 m of pillowed

tholeiitic andesite. (For a detailed chemical description

of volcanic units see report by Pattison 1984). It is best

exposed between lines 8 and 16 west at 8+OOS. Rusty brown

iron staining occurs where the andesite is in contact with

the overlying rhyolite. South topping pillows are well

8 developed and are slightly elongated having a 3/2

length/width ratio. The rock is medium grey green when

fresh and weathers light grey. Chlorite-carbonate-sulphide

amygdules up to 15 cm across occur throughout the andesite

flows.

Underlying the tholeiitic andesite are normal

tholeiites. Large outcrops of massive pillowed and flow

brecciated tholeiites occur to the north east from lines O

to 8 west and O to 8 north. This south topping sequence is

intruded by a gabbro sill along baseline 0+00. Northerly

trending diabase dykes of the Matachewan Swarm intrude the

sequence. Thick massive flows ( 75 m) are fine to medium

grained. Pillowed flows are generally light to medium

grey-green and quartz carbonate amygdaloidal.

The south limb stratigraphy commences with massive and

pillowed high magnesium tholeiites which measure about 400

metres thick. These rocks are generally hard and have a

pale to medium green colour. North topping pillows average

60 cm long by 40 cm wide. A conformable gabbro sill

measuring about 150 metres thick underlies these high

magnesium tholeiites.

ECONOMIC GEOLOGY

Considerable ( 3(^) pyrrhotite-pyrite with traces of

chalcopyrite and sphalerite occurs in pillowed tholeiitic

andesite beneath tholeiitic felsic flows between lines 8 and

16 west at about 8+00 south. Extensively mineralized

samples from three pits along this horizon contained from 50

to 94 ppm copper and from 240 to 720 ppm zinc. A rusty

rhyolite flow top sample contained 1100 ppm zinc.

Mineralization encountered in previous drilling is discussed

under previous work.

ALTERATION

Sericitization, chloritization, silicification and

sodium depletion are weakly to moderately developed in the

tholeiitic rhyolite. Strong sericite and chlorite is patchy

and best developed in dark flow lobe-like features which run

subparallel to the strike of the rock (J. Pattison 1984).

Sodium values in the rhyolite are variable (Figure 7).

On a local scale Kirwin (1985) noted an increase in

alteration towards the west within the tholeiitic rhyolite.

He noted an enrichment of K, Mg, Fe and Pb/Sr and the

depletion of Na and Ca along strike which are typical

chemical trends surrounding an alteration pipe beneath a

being local and relatively mild so Kirwin attributed it to

the result of localized seawater convection through the

rhyolite fragmental rather than from a nearby hydrothermal

vent.
