A GEOLOGICAL

SURVEY

OF THE

DIMENSION STONE RESOURCES ON THE

BLACK

LAKE PROPERTY

THE PARRY

SOUND DISTRICT

OF ONTARIO

SUMMARY

The

Parry

Sound area of Ontario is underlain

by

complex gneisses

and

migmatites of Middle to Late Proterozoic

age which

are

part

of

the Ontario s egment

of

the

Central Gneiss Belt of the Grenville Structural Province. A working model of thrust plates

(called domains and sub-domains) which are separated by

ductile

thrust faults and moved

in

a northwes terly direction

upon each other has

been

postulated

by Davidson

et

al (1982).

Easton (1992)

has

improved this

model

in

his

synopsis using

a

hierarchy of terranes and

domains w herein

the

terranes

include domains of similar age

which are autochthonous

with

respect to each other. Age dating has indicated that four of these large

scale

terranes or

plates are

stacked

on

each

other

with the

base being near Sudbury at

the Grenville

Front

and

the

top being near

Kingston.

Despite the recent wealth

of scholarly publ ications

a

comprehensive

geological map has not

yet

been

made

available for the area. However,

the

limited

information

available

has enabled the clear identification of potentially favourable

conditions

for

both

flagstone and dimension stone. Several

flagstone

occurrences cluster along

Davidson's

thrusts

and

several potential dimension stone prospects have been identified

within the interior of particular

domains.

Although one may ordinarily not expect to find

dimension

stone

within

tectonite

terranes,

it

is

evident

that

the

autochthonous nature

of

some

of

the domains

combined

with annealing effect of later superimposed amphibol i te

facies metamorphism

preserved large

competent blocks

of migmatites and

gneisses.

As a result

o f mapping

dimension stone potential, and sawing an d po l ishing

specimens from many prospects. Seven sites in the Bri tt domain, and one in each of

the

Rosseau and Moon

River

domains have been staked and mapped by

the

writer result ing

in

the

definition of a large number of potential quarry sites. The ten claim

unit

Black Lake

property is one of these.

The property

is

underlain

by

the

Bolger pluton

which

is a

circum

1450 Ma

megacrystic granite intrusion. A

highly

strained m egacrystic unit trends

northeasterly

across

the northwestern portion

of

the property bounded on the southeast

by

derived complex

migmatites.

The

migmatite in

the

south half o f lot 26

concession

II

has been

drill

tested

and

test quarried

with positive

results. A

detailed site plan is warranted coupled w ith a larger

quarry test. The site planning

is planned

for the

Spring of 1996.

INTRODUCTION

In 1991,

the writer commenced a

project to

evaluate the

f lagstone and

dimension

stone

resources

of

the

Parry Sound area. At

the

same time efforts

by

former

Ministry

of

Northern Development and Mines

geologists, principally Chris Marmont and

Dave

Villard,

were being made to

outline the

sub stantial potential

for

these stone resources

and make

the publ ic aware of the opportunity. In 1992,

the regional investigation

of

flagstone resources

by

the writer proved discouraging. It

was

decided

late

in the

field

season to focus s olely on the

dimension stone potential.

By the end

of 1992,

many prospective dimension

stone

sites

had been

identified

by

either government publ ications

or

by the writer's prospecting. Nine of these

dimension

stone propert ies have

now been staked

by

the writer, and

an initial evaluation

of

each property

involving

geological

mapping of

the

outcrops

at

a

scale

of 1:5,000 has

been completed. The work

provides

an initial

evaluation

of potential quarry sites on each

property.

The

project

has

been

supported by

the Ontario

Prospector's

Assistance

Program

in 1992,

1993

and

1995.

In October, 1992, a

two

claim unit portion of the

Black

Lake property was

staked for

its dimension

stone potential.

Geological

mapping

was carried

out

in 1993.

In the

meantime

an

adjacent

property being tested by

Pacific

Granitestone

Ltd. lapsed and

the

writer staked eight claim units

in

October,

1994.

The acquired claims contain one quarry

site

from

which Pacific

Granitestone removed

seven large blocks

for processing. This report

is the

result

of

mapping

of

the eight

claim

units on

a 1:5,000 scale.

The format

of

the geological

report

is

formulated

in

compliance with

assessment submission requirements.

LOCATION

AND ACCESS

The property is located

in

Burton Township, Parry Sound District, Southern

Ontario Mining District, and Sudbury

District Regional

Geologist's area approximately 165

miles

(264

km)

north of

Toronto (Figure 1). The

property is

bounded

by

longitudes

80

0 10'41"W

on

the west

and 80

0

10'41"W on

the east

and

latitudes 45 0 37'19"N on the

south and 45 0 38'40"N

on

the

north.

The corresponding UTM co-ordinates in metres are

564,031 on

the

west, 565,800 on the

east,

5,052,150 on the south

and

5,054,342 on the

north.

The

property

is

within

National

Topographic

System

area

41H/9

and

is

recorded

on

claim map G3884.

The Black Lake property

is

in Burton Township,

and can

be accessed

by a

hydro access

road

which leads

one

some seven ki lometres

west

of the town of Ardbeg.

Ardbeg

is

at the western terminus of Highway 520 which can be reached

by

exiting Highway

124

at

Waubamik,

1 1 kilometres northeast of Parry Sound

and

following

a

secondary

road

for twenty

five kilometres

to the

north.

PROPERTY

The Black

Lake

property comprises approximately 500 acres and is more

particularly

described

in TABLE 1

(Figure 2).

Assessment

will

be

filed for the current work

on

the

claims,

and

it

is

anticipated, as a result, that

sufficient credits

should be

available to keep the entire claim

group in good standing for some two years from

the

date of submission.

Preparation

for

field

work involved production o f 1:5,000 blow

ups

of data from

Ontario Base

Maps

and 1:30,000

air

photographs.

A grid was

overlain

on

the maps, and

stat ions

for

recording observations

at approximately

100

metre

centres were plotted

and

coded. Due

to

the

high

percentage of outcrop, visual control was feasible in almost all

cases,

but

traversing

by

pace

and compass

from known sites

was

sometimes

supplemented by

the

use of a rangefinder. The ma gnetic

decl ination used in the

field

work

is

10 0

-15'W.

At each station

rock

types with variat ions

were noted generally with a visual

description of colour and textures. Foliations w ere described and measured where pos sible.

The main emphasis

was

in measurement of

oints

and

their

separations. In

this respect

at

each station

joints

were

observed

within

a

50 to

100

foot radius

of

the

station.

The attitude

of

each joint was

recorded with the minimum

and

maximum spacing

observed

and

the

average spacing estimated.

Observations were

directly

recorded on

a dictaphone in

the field. The verbal

record

was

later transcribed

to paper

notes. Drafting

of

the data

onto maps

was later

done

from the paper notes. Statistical

plots

of the joint measu rements

and joint

separations were

constructed

on

the 1:5,000

map sheet.

PREVIOUS GEOLOGIC L WORK

A

traverse

of the shore of Georgian Bay

was

made by Alexander Murray in

1848, and

he gives

a

brief accoun t

o f

the

geology of

the shorel ine (Mu rray

1848,

p.45,46).

The shorel ine of Georgian Bay was again examined

by

Robert

Bell in 1876

(Bell

1876,

p.

198-207).

The

Huntsville -Bracebridge area

was

investigated by

W.A. Parks

(1900,

p.

121-

126), and brief notes on the geology are given. Further field work was

done

in

the

area in

1905 by T.L. Walker (1905,

p.

84-86).

The

International

Geological Congress

had a field

excursion in Parry Sound

area

in

1913.

Some

local geological

features are

described by

T.L Walker

(1913,

p.

98-100).

The adjacent portion of the property,

claim

SO1151134, was

mapped

in 1993 by

the

writer. As well

the

current claims

are

within an area previously

mapped, (Lashbrook,

1990),

drilled

and

quarried (Innes,

1992)

by

1886

Holdings Ltd.

The

first

comprehensive reconnaissance

mapping in

the area

was done

by

Satterly (1942)

who

visited all the

local

known

mineral

deposits.

Satterly

(1955) also

mapped Lount

Twp.

in

detail showing

for the first

time

the existence

of

mappable units

in

the

Parry Sound area. Hewitt (1967) was able

to

accurately identify the complexity

o f

petrographic

units

and correlate

some

of these

in a reconnaissance mapping program.

Greater

interest

in

resolving the geological

complexity

of

the

area

was

kindled

by Lumbers

who was

progressively

mapping

Grenville

terranes in Ontario from the Gren ville

Front to

the

south Lumbers (1975) and by Wynne-Edwards (1972). Wynne-Edwards

suggested the f irst interpretive

framework

for the Central Gneiss Belt

of

the Grenville

Structural Province. The controversy which arose from Wynne-Edwards

"Sea

of Gneisses"

lead

a

profusion of

other

researchers into

the

area

who

have conducted specif ic detailed

and

reconnaissance

mapping

and

synoptic

studies.

Since

1972

M.

W.

Schwerdtner

and

students have concentrated

on

resolving

many

of the structural geology problems of the

area contributing a great amount to the understanding of the

geology

of

the

Central Gneiss

Belt.

The framework for

all current

work

in

the area was provided

by Davidson et

al. (1982).

This has

been modified

subsequent ly by Davidson and other

workers, and

Easton (1992)

has

synthesized this work eloquently.

The

tectonic terranes

and domains

separated

by

shear zones have become imbedded in the l iterature.

This view has been

further

modified by some more local

studies

by

Hanmer

(1988) and Schwerdtner (1987).

According to Hanmer

the southeast to northwest thrusting

was initiated

at

approximately 1160

Ma

and continued

for 100 Ma. However

he daims

that

subordinate northeastward

thrusting

was coeval

and that

late

synmetamorphic extensional

shears cut these

major thrusts

and thrust sheets but are

in

turn cut by late

movement

on

the thrusts. He further

alludes

to

the

comparison

to

the structural

style

of the Central

Gneiss

Belt and the Himalayas suggesting that the Grenville exposes

the architecture

and

processes presently

active

in the roots of younger mountain

belts.

Schwerdtner^

Pag f



observations agree

with Hanmer's respecting

a

northeasterly

component

to

deformation

which he invokes to

explain

north-south

buckle folds.

However, Schwerdtner observed that

not

all fol iations can be explained

by

the thrust model

and

that three sets of folding are

superimposed

and cross

the

domain boundaries. He

claims

that

all

the

structural

facts

can

be explained

without large

differential translations o f

crustal

sl ices

and

most

discordances

in

the

regional

gneissocity

could have b een created

by

decol lement and

repeated

buckl ing.

Easton

(1992) synthesized all previous studies stating that, "Recorded w ithin

the Grenville Province is the tectonic evolution of the southeast margin of Laurentia during

the

Mesoproterozoic.

The

Grenville

Orogeny

has overprinted

the structural trends

and

metamorphic effects o f the

Archean and

Paleoproterozoic geological

province of

Laurentia.

It is now

generally accepted that

this

orogenic

event

or events

involved

northwest directed

thrusting and imbrication

of

the entire

crust,

presumably as

a result

of

a

terminal

collision

at

about

1100

Ma.

with

a

continental landmass somewhere to

the

southeast.

The Central Gneiss Belt consists

mainly of

upper amphibolite and local

granulite facies, quartzo-feldspathic gneisses, chiefly of igneous origin with subordinate

paragneiss. Distinctive

l ithotectonic

terranes, some further

subdiv ided

into

domains, have

been

identified within the Central Gneiss

Belt.

The

terranes

and

domains

are distinguished

by

differences

in

rock

types,

internal structure, metamorphic grade,

geological

history, and

geophysical

signature

and are bounded by zones of

intensely

deformed

rocks traceable

for

tens

of

kilometres."

The Algonquin terrane consists of

1800

to 1600 Ma

gneisses

intruded by 1500

to 1400 M a granitic and monzonitic plutons

that

may represent

an extension

of

the Eastern

Granite-Rhyolite Province. Although imbricated by later thrusting

the Algonquin

terrane is

probably parautochthonous. The Britt

and

Rosseau domains are part of the Algonquin

terrane.

The Britt Domain (Figure 4)

comprises

a

complexly deformed and

metamorphosed

series

of

rocks.

Although some

of

the

rocks are metasedimentary in origin

the preponderance

of

the

rocks were

originally

plutonic, but have

been changed

by

dynamic

and thermal metamorphism. The f inal stages of this metamorphism appear to have

annealed

the

rock

into a compact and durable material having some

relict

textures and

many

overlapping

and lively features. Dips of these rocks are

generally

flat

to

10

0 to the

southeast. Some

units are entirely

composed

of

isoclinal sheath folds whereas other units

are evidently

deformed

megacrystic granitic plutons.

The Parry Sound and M oon River domains consist chiefly of uvenile crust

1450 to 1350 Ma in age and are paral lochthonous. The Parry Sound

rocks

comprise dense high metamo rphic facies rocks (amphibolite and granulite facies) which are

migmatit ic gneisses

produced by

injection

and

of

metamorphic gneisses

of

various

types. The rocks are mainly

of

upper amphibolite and

granulite

metamorphic

facies.

Hypersthene-bearing chamo krtic gneisses are

present

in

the

area.

The

origin

of much of the

amphibolite

gneiss is obscure. Some which is

associated

with

bands

of

marble

is

thought

to

be

paragneiss

whereas

som e is proximal to

large bodies

of

gabbro and

anorthosite an d thought to be o rthogneiss. Trusler

and

Villard (1980) found evidence that

some of

the

mafic and

felsic

rocks are of volcanic origin. The

high metamorphic grade

of

the rocks

is attr ibuted to a

deep seated

origin possibly

involving

underplating at

an

early

stage.

The

Bolger pluton

in

the Britt domain is dated at

circa

1450

M a and un derl ies

the Black

Lake,

Woods

Road and

Shebeshekong

Lake

properties (Figure

4).

The Dillon

Road property is underlain by both

the

Bolger pluton and

the

Ojibway

gneiss

association.

The Killbear

Point

and Jacknife

Harbour

properties are underlain by the Sand Bay gneiss

association.

The Grundy

Lake property

is

underlain

by

an unnamed V-shaped pluton

believed to

be

circa

1450 Ma.

Comparable regional

maps

do

not

cover

areas about the Turtle Lake

property

and the

Burnt Lake property

which are situated in the Rosseau and the Moon River

domains respectively.

DESCRIPTION OF

ROCK UNITS

Since no comprehensive, detailed geological

maps

have

been produced

for

the Parry Sound area, none of the previous

workers

have made an attempt to construct a

table of rock units.

None

of

the

rock units have been

correlated across

domain boundaries.

Trusler and Villard made an

attempt to

derive a Table of Rock units for the Parry Sound -

Sans Souci

area in 1980 and

some

of that

information is used here to produce Table

2.

These Formation names are not used in the mapping since these have

been inadequately

defined for

inclusion

in

the

literature.

However,

the

area mapped by Trusler

and

Villard

covers

parts o f

the

Britt, Parry Sound and M oon River domains and

the l ithologic variety

is

The Sans Souci-Killbear Point Group correlates well w ith the Sand Bay gneiss

association of Figure 4

which

underlies

properties.

Similar

The Ojibway gneiss

association

which underlies

The

remaining si tes are megacrystic granites or

migmatitic

derivatives of

megacrystic

granites classified

under

quartz monzonite

in Table 2.

The rocks on the property have been subdivided into mappable

units

as

follows: bioti te-homblende

migmatite,

megacrystic granite, gabbro, and tonalite.

Paae

9



The biotite-homblende

migmatite is represented

by quartzo-feldspathic rock

ranging from less than 5 0 7 o to

greater

than 40 07 o mafic minerals and containing

syntectonic

and late tectonic pegmatitic

material

in varying proport ions and thicknesses.

The

grain size

ranges

from fine

to coarse w ith the

more

neosome phases

generally being

coarser. In any

one

area

and

especially

in individual

layers the mineralogy and

textures are

uniform.

The

mafic mineral

tends

to

be

bioti te dominant al though

hornblende dominant sections

are

present and frequently

alternate layers

switch dominance of

the mafics. The gneissic fabric

is very thinly laminated in

some

areas but ranges to

thickly

layered in other

areas

and is

typically variegated pink

and

various

shades

of grey.

A prominent

mineral foliation is

frequently

superimposed on the

gneissic

fabric. Hematite staining frequently

contr ibutes

a

dark

red

fleck to the rock.

The megacrystic granite

is a highly

strained to

gneissic pink

and

grey

rock

containing relict

pink

orthoclase phenocrysts

from

2 to

5 cm

in

original diameter which

have

been stretched to form a prominent l ineation. Rarely this

lineation

is

also

folded. The

orthoclase

comprises 20-50

0

7 o

of

the

rock.

Biotite or hornblende

at

between

10

and

20

0 7 o ,

quartz at ID-20% and plagioclase are also present.

The granite

grades into

the

migmatite,

and in reality

the

granite forms

the

paleosome

constituent

or progenitor of

the migmatite.

The tonalite comprises

two

varieties: a gneissic to slightly layered rock

containing

2-3

cm pink orthoclase pheno crysts and a gneissic, medium to

coarse

grained,

thinly to thickly layered rock. The latter is variegated light grey and greyish black

and

contains

20 to 40 0

7 o

mafic

minerals

overall with amphibole

being the dominant

mafic mineral.

In the gneissic variety, usually approximately 10 07 o , but

occasionally

up to 50 07 o of

the

rock

unit

comprises

introduced or anatectic, syntectonic

quartzo-feldspathic

material. Pinch and

swell

characteristics

are common especially

in

neosome port ions

of

the gneissic

rock.

The

gabbro is

represented

by a

very coarse grained, greyish black, coronitic

metagabbro

which

has an ophitic

and

oikocrystic texture. The joints where seen on this

particular outcrop

are

three

metres apart.

PROPERTY GEOLOGY

The property principally

is

underlain by felsic rocks of unusual character

of

Middle to Late Precambrian age. The property is underlain by

the Bolger

pluton, and

relict

portions

o f megacrystic granite,

tonalite and

gabbro

give evidence

to this.

However,

polyphase

metamorphism

and

tectonic

deformation

are evident

in

migmatites generated

from the megacrystic granites.

The individual rock

units were

described

under the heading DESCRIPTION

OF

ROCK

UNITS on

Page

9 of

this report. The megacystic granite exhibits cataclastic

textures

in all outcrops.

In the

areas o f

greater preservation the orthoclase phenocrysts

are

elongated exhibiting uniaxial strain and recrystallized to a

sugary

grained aggregate of

pink

crystals. The stretching ratios vary from five to one to twenty

f ive to one.

Where the

cataclasis becomes more pronounced,

a

gneissic foliation

is induced

both

by the apparent

banding from stretched phenocrysts and also by differential cataclasis yielding layers

having

different

grain

sizes.

The megacrystic granite

is

still recognizable

within

the migmatite although the

stretched phenocrysts are

not

preserved or recognizable.

In

the migmatite the biotite

composition

o f

the paleosome

constituent is enhanced

to approximately 20 07 o (10 0X o overall)

and forms

a

prominent foliation

frequently

with

minor

al igned red

hematite

spots w hich is

at an acute angle to the gneissic foliation imparted from

interlayering

of the neosome

consti tuent with the paleosom e

material.

The neosome constituent is relatively uniform

in

composit ion,

pink to

red,

fine

to rarely medium grained, and a

hypidiomorphic granular

quartzo-feldspathic aggregate. This material

is

extremely attractive,

and

the

textures are

uniform

over

a

large

area despite the

fact that

at

least

two

and

possibly

more phases are

involved in the genesis of the rock. This

is

the principal target material on

the

property.

Neither variety of tonalite

exhibits

consistency in texture over

a

large area.

The

gneissic to

slightly

layered tonal i te containing

2-3

cm pink

orthoclase

phenocrysts is

very restricted in extent although the rock

is potentially

quite presentable

and

the joint

spacings are sufficiently large

to

enable some quarrying. However, this material

is

restricted

to claim 1151134

which was mapped and described in 1993 (Trusler, 1993a).The gneissic

tonali te

is a medium

to coarse

grained,

thinly

to

thickly layered rock contains significant

variation in texture

and

composition o f the syntectonic

and

late tectonic pegm atitic material

Some

portions

of the unit contain rich biotite

segregations which

weather

low

although

amphibole is the

main

mafic mineral. The gneissic variety com prises usual ly a pproximately

10 0

7 o , but

occasional ly

up to 50

0

7 o

introduced

or

anatectic, syntectonic quartzo-feldspathic

material. Pinch and swell characteristics are common

especially

in neosome portions of the

gneissic

rock.

The gabbro is represented b y

a

very

coarse

grained, greyish black,

coronitic

metagabbro which has an ophitic and

oikocrystic texture

where seen on claim 1151134.

The joints where seen on this particular outcrop are three metres apart. The coronas are

produced

from partial amphibole replacement o f cl inopyroxenes. This also is

a

candidate

rock unit for quarrying as a dimension stone. Within the current map area,

however,

the

gabbro

is

all of

a

gneissic variety with 50 07 o introduced n eosome m aterial and with much of

the

hornblende inverting to biotite.

Gneissic

foliations

were measured at each station

where

possible. Despite

some

exceptions,

the general

pattern displayed is

of

a relatively

structurally

uniform

sequence.

The gneissic

foliation is prominent on al l parts of

the

property and generally

strikes northeast

and

dips to the south. However

substantial

dip variation occurs

and it is

suspected

that several

recumbent folds are

situated on

the property. The lineation as well

as

hinge

lines of many minor folds seen trend to the so uth or southwest at a 10-20

0

plunge.

In general the joint spacing in

the

rocks

throughout

the

property

is

widespread. The vertical joints

have

an average separation, based on 359 data (300 data

from current

mapping

program), of 2.5

metres

and the average sub-horizontal joint

separation, based on 47 data

(38

from current program),

is

2.0 metres. Twenty per cent of

the

vertical

joint data,

based

on 396

data(

330 from

the

current program),

are

clustered

between 45' and

75

3 13

07 o of

the

data

are clustered

between 100 C

and

125

0 and 14 0

7 o O f the

data

are

clustered between

150

0

and

165".

Locally, a

consistent stronger preferred

orientation

of

joints

is normal.

P O T E N T I A L DIMENSION STONE SITES

A potential dimension

stone

site is located to

the

west of

the

hydro line road

in the south

half

of lot

26,

Concession

2,

Burton Twp. The area is 300 metres X 400 metres

and rises 10

metres above the surrounding

area.

This area hosts similar material

to that

material

pictured in

pictures

1

and 2 and is imediately

west of the

quarry

depicted in

picture

3.

The

polished

specimen is

described

in

Table

3 of Trusler, 1992. The

site

has 80 07 o

outcrop, and

the remainder

of

the

area is

covered

by brush and low trees. A

site

plan

with

detailed

mapping

will

be needed to orient the next

phase of

work.

Initial

work was

started

on

this

and

will

resume in the Spring. This

is

the

higher

priority site for further

evaluation.

A second site located in the middle o f lot 25 concession I I I has similar material

occurring

in

an area SOOmetres X 600

metres

and partially straddling the access road. Much

of this

hill which rises

up

to 15

metres

above the surrounding area would

yield

large

consistent blocks. Portions of this site

should

also be

further evaluated.

CONCLUSIONS

The Britt domain comphses a comptexty

deformed

and metamorphosed series

of

rocks

Although some

of

the

rocks are metasedimentary

in

origin the

preponderance

of

the rocks

were

originally plutonic, but have been

changed

by dynamic and thermal

metamorphism The final

stages of this

metamorphism

appear

to

have

annealed the rock

into a compact and

durable

material having

some

relict textures and many overlapping and

lively features

Nine dimension stone

prospects were staked

in

the

Parry

Sound

area, and

all have

been mapped

geologically

Many

of the rocks

underlying

these

properties

are

migmati te

derivatives

of granitic intrusions and

present

a

great

variety of textures In

some

cases it is evident

that the paleosome

const i tuent was megacryst^ and subsequent

neosome phases

have distinct

composit ions

and

fabrics

The sites

were

chosen

for their

attract iveness and the apparent availability of accessible

large

blocks.

Two sites on

the currently mapped

portion

of the

Black Lake

property warrant

further

attention. Both si tes are underlain by a variegated migmatrtic derivat ive of

megacrystic granite, covering areas 300 metres X 400 metres

and

400 metres X 600

metres

respectively These two areas contain a significant dimension stone resource and

the one area is part ially developed with a quarry and drill tested. Site planning, detailed

mapping, and a quarry test are required on the first srte This process is to be

completed

in

the Spring of 1996.



RECOMMENDATIONS

It

is recommended that

the

site underlain

by

migmatite on lot

26,

Concess ion 2,

Burton

Twp.

be mapped

in detail

and that

a

site plan

be prepared which

would

enable licensing

of

a

quarry

site.
