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.
