Introduction

The Knucklethumb Lake property consists of eighteen contiguous

'unpatented claims. The scope of this report concerns itself with

thirteen claims numbered 71^^50 to 718462, inclusive. An addition

al five claims were staked due to favorable results,

The claim holder is Stephen N. Roach residing at P.O. Box 892

( 36 St. Therese Blvd. ), Embrun, Ontario.

Location

The Knucklethumb Lake property is located in Oboshkegan

Township. The claim group is approximately fifty-three kilo

meters north of Jellicoe and seventy-two kilometers northwest of ~"

the town of Geraldton ( Figure l ).

It is bounded by Latitudes 50O 09' 36" and 50O 11' 32" N and

Longitudes 8? 0 32' 25" and 8? Q 34' 56" W,

Access

A lodging road extending north for 100 kilometers from the

Trans-Canada Highway 11 comes within six kilometers of the claim

group. A Canadian National Railway line comes within six kilometers

north of the property ( Figure l ). However, access is restricted

to float-eqipped aircraft that can be chartered from Jellicoe or

Geraldton.

Survey Method

A grid was established as a reference for conducting a mag-

n^tometer survey between August 19, 1984 and August 24, 1984,

The grid was also used in performing geological, lithogeochem-

ical, and VLF-EM surveys during the summer.

A total of 2Q.3 kilometers of line was cut and chained with

cross-lines established every 100 metars and station spacing at

25 meter intervals. The baseline { BL ) and tieline ( TL/700 N )

trend in an east-west direction with cross-lines being north-

south.

The magnetic survey was conducted using a MF-l fluxgate mag

netometer at a 25 meter station spacing. Half-station readings

were carried out over strongly magnetic and mineralized zones.

The 1000 gamma scale was primarily used on the fluxgate magneto

meter. The operator was always facing south and the instrument

was accurately levelled before a reading was taken. The magnetic

survey was performed by the author.

A number of base station readings were taken in order to

correct for the diurnal variations of the earth's magnetic field,

Base stations ( A ) were establised at BL/300 E, BL/900 E,

BL/1500 E, 3L/300 W, and TL/300 B,and are summarized in Table l,

Base station readings were repeated after an interval T, between

one and two hours. If the repeat reading showed an increase d,

every reading taken during the interval is diminished by the amount

d x t X T where t is the time at which it was taken after the in

itial base station reading.

A total of 1562 readings were taken,

por the most part, the watershed is high producing lowlying

and flat spruce and alder bog, and cedar swamp areas ( i.e. north

of BL/500 W and TL/700 E ). Outdraining strums, such es the

Sandberg and Jaz Streams, from these swampy areas are evident.

Also, wet, grassy areas on the northern shoreline of Knuckle-

thrornb Lake is prominent. The Jaz Stream flows intermittently

southward towards Knucklethurnb Lake, The Sandberg Stream flows

northeastward to a branch of the North Onaman River.

Areas of higher relief are to be found in the northeastern

( i.e. Line 1000 and 1100 E ), southeastern ( i.e. Lines 1400

to 1800 E, inclusive), and western ( i.e. Line 1100 and 1200 W ).

parts of the property. These areas have frequent outcrop exposures

and local boulder areas. The outcrop exposures are generally flat

and low-lying with a fairly thick mosp cover or are to be found

on sides of sloping hills. Approximately 5?; to lOfi of the property

is covered by outcrop,

The general tree cover is spruce balsam in flat humocky and/

or grassy ground. There are local areas of alders and cedars.

Areas of higher relief have a mixture of white spruce and spruce

balsam with scattered poplar or aspen trees.

Previous Mineral Exploration

The Knuckleth imb Lake property has undergone extensive

mineral exploration in the early lQ80's.,A joint venture between

Canamax ( i.e. previously Amax Minerals ) and Labrador Mining and

^xoloration ( i.e. previously Hollinger Argus ) in 1979 initiated

extensive exploration activity in the Metcalfe Lake area and -

Oboshkegan Townshic. Part of the explored area is the Knuckle-

thumb claim group. Exploration activity in 1980-81 included

VLF-EM and magnetic surveys and 835 meters of diamond drilling,

Only 463 meters of drilling was performed on the property. A

summary of the drilling is presented in Table 2,

In 19?6, N.W.T, Copper Mines Limited drilled a hole in what

is now claim 71845*4-. The drill hole was to test gold-bearing

quartz veins on surface. The hole intersected unmineralized

chloritic pyroclastic breccia with localized quartz veining.

There is no mention of geochemical analyses.

Prior to the most current exploration on the property, there

is much evidence of exploration activity in the way of trenching.

There appears to be four areas of trenching and are confined to

mineralized zones containing pyrite and/or quartz veins. The

four areas are i 1) Line O to 200 W, just south of the baseline,

2) between Line 600 E and 900 E, just north of the baseline, 3)

in the southeastern area between Line 1500 E and 1800 E, and 4)

between Line 700 E and 800 E, north of the tieline. There is no

evidence of drilling in those four areas other than that which

has been described.

Late Precambrian metavolcanics underlie 65^ of the Metcalfe

Lake area and Oboshkegan Township. A sequence of iron and magne-

sian-rich tholeiitic basalts to ca&c-alkaline rhyolites are re-

presentat^ve of the metavolcanic assemblage in the general area.

Andesitic metavolcanics are rare. Thin metasedimentary and vol

caniclastic units comprise 5^ of "the area and are usually found

at the top of metavolcanic units. The rocks have undergone

greenschist metamorphism.

Early Precambrian granitic rocks comprise 30# of the general

area. Both the metavolcanics and metasediments are intruded by

diabase, lamprophyre, and granitic dykes and sills.

The metavolcanics and metasediments have "been subjected to at

least two periods of deformation with the first one producing

a penetrative regional foliation. The second one produced a cren

ulation cleavage, although there may be other crenulation cleav

ages.

The metavolcanic stratigraphy represents sequences of ash

flows superimposed by folding.

Geology of Knucklethumb Lake Property

The property consists of 9^ felsic to intermediate metavol

canics, 59^ mafic metavolcanics, and 1# metasedimentary rocks.

Thin lamprophyre dykes cross-cut the metavolcanics. A small

granitic intrusion lies to the south of the property,

The felsic to intermediate metavolcanics underlying the

claim group are part of a longer and thicker sequence that extends

26 km and has a maximum thickness of 2,7 km. The felsics attain

8

a maximum thickness of I.? km.on the property. These rocks

are predominantly pyroclastics and are interpreted as ash flows.

The felsic to intermediate metavolcanics have been extensively

altered with the presence of chlorite * carbonate, sericite t

carbonate, quartz 4- sericite, and chlorite * sericite A car

bonate * talc.

Although the mafic metavolcanics constitute 5# of the property

two different mafic units are recognized. The two different mafic

units are: 1) iron-rich tholeiitic basaltic flows ( i.e. pillowed

and massive ) located in the northeastern part of the property, and

2) calc-alkaline basaltic debris flows located in the southeastern

part of the pronerty.

The metasediments have only been recognized in the southeastern

part of the property. These rocks are predominantly laminated

mudstone and siltstone with interbeds of greywacke, arkose, and

sandstone. The lateral extent of the metasediments to the west

is not entirely known. However, drill hole data from 030SH 2 -

6-81 suggests the presence of altered metasediments.

There are two thin units of cherty tuff/chert that are in

terpreted as chemical metasediments. These two units are: 1)

cherty tuff horizon ( exhalite ) that is located in the northern

part of the property and hosts Au-Cu-bearing pyrite mineralization,

and 2) cherty tuff/chert unit that is located in the southeast

ern part of the property and hosts Au-bearing pyrite and arseno

pyrite mineralization.

There are numerous felsic to mafic dyke and sill-like bodies.

Lamprophyres are the most common of the dyke and sill-like

bodies, A granitic intrusion lies to the south of the prop

erty and there is no visible contact with the surrounding felsic

to intermediate metavolcanics. However, the felsic rocks en

countered in OBOSH 2-6-81 are extremely altered with the

presence of chlorite * sericite * carbonate * talc.

Discussion of Magnetic Data

The magnetometer survey was successful in outlining litho-

loelcal units/horizons, structural linaments, and mineralized

zones. These geological features may associate with one another,

and subsequently have a common magnetic association.

The strong magnetic expression in the northeastern and south

eastern parts of the property reflect the mafic metavolcanic

lithological units. This magnetic expression is in marked con

trast to the lower magnetic character of the felsic to intermed

iate metavolcanics. The granitic rocks and metasediments generally

have a lower magnetic susceptibility than the felsics. Geological

contacts are, for the most part, magnetically inferred because

of the paucity of outcrop exposure and the absence of recognizable

lithological contacts.

There are a number of structural linaments that have been

inferred upon examination of the contoured magnetic data. The

interpretation of structural linaments from contoured magnetic

data can be summarized fromi 1) thin, continuous, and highly mag

netic linears or strongly, negative magnetic linears,(~i,e-shears,

fault zones, and dyke swarms ), and 2) discontinuities and/or

10

inflections of lithological units/horizons that may be char

acterized by a prominent magnetic expression ( i.e. fault

zones ).

Contoured magnetic data was successful in suggesting the

presence of sulphide horizons, such as those encountered in

OBOSH 2-6-81. These zones generally have a strong magnetic

attraction and this is due to the presence of magnetic sulphides

such as pyrrhotite and pyrite mineralization in OsOSH 2-6-81.

However, there is the possibilxy that oxide iron formation { i.e.

magnetite/chert ) coincide with these magnetic zones, Magnetite/

chert iron formation commonly occurs in the region, especially

in the mafic metavolcanics.

There are five prominent magnetic expressions or attractions

that reflect the three geological features that have been discuss

ed. These anomalies are i

Anomaly A

This magnetic anomaly is found in the western part of the

property. The magnetic expression increases gradually and lat

erally westward from Line 600 W. This magnetic area is contin

uous and has a fairly wide magnetic 'width 1 .

The highly magnetic nature of this area is represented by strong

ly sheared felsic to intermediate metavolcanics that host very-

fine grained disseminations of M magnetite. These rocks are re-

copnized between Line 1000 W and Line 1200 W. However, the strong

magnetic nature of these rocks do not reflect a more mafic litho

logy.

11

There are numerous, thin, and strongly magnetic linears

within the anomalous area. This is evident on Line 1200 W.

One of these linear zones coincide with strongly sheared and al

tered felsic to intermediate metavolcanics containing weakly

disseminated magnetite. The interpretation and presence of a

shear zone is a likely explanation for other zones of similar

magnetics,in this anomalous area.

Anomaly B

This anomaly is located in the southern part of the property.

The magnetic anomaly coincides with a VLF-EM zone. This continuous

magnetic expression increases laterally westward from Line 1000 E.

The magnetic 'width' is variable. This particular anomaly is

in marked contrast to the lower magnetic susceptibility of the

felsic to intermediate metavolcanics.

Drill hole data from OBOSH 2 - 6 - 81 is the only evidence

of rock types characteristic of this anomaly. Mineralized sections

of pyrrhotite and pyrite in altered graphitic and felsic tuffs and

metasetliments were intersected in OBOSH 2-6-81, The magnetic

anomaly directly coincides with the sulphide sections and graphi

tic tuff horizon in the drill hole. This anomaly definitely re

presents an altered lithological unit ( i.e. metasedimentary )

hosting a pyrrhotite-rich horizon.

Anomaly C

This anomaly is found in the southeastern part of the grid.

This northeasterly trending magnetic expression consists of

12

multiple, thin, and strongly magnetic linear zones.

The strongest magnetic attraction of this anomaly occurs on

Llhfe 1'500 E and coincides with magnetiferous mafic metavolcanics

that host disseminated pyrite. The magnetic attraction diverges

from the VLF-EM zone, and subsequently.from the sulphide zone,

eastward.

This particular anomaly may represent a mafic lithological

unit and/or a fault/shear zone. Both these geological features

may commonly associate with one another in this magnetic anomaly.

The presence of mafic metavolcanics between Line 1600 E and Line

1800 E is equivocal because of the surrounding felsic to inter

mediate metavolcanics and the lack of outcrop exposure in the

anomalous area. It remains to be seen, but this magnetic anomaly

may be similar to Anomaly A f and represent sheared and fractured

felsic to intermediate metavolcanics hosting magnetic sulphides and

oxides.

Anomaly D

This particular anomaly is located in the northeastern part

of the property. There is a strong continuous magnetic attraction

eastward from Line 600 E, The magnetic''width' is fairly wide and

consistent. The magnetic survey was .particularly successful

in outlining the mafic metavolcanic unit.

This high magnetic expression is characteristic of iron-rich

tholeiitic basalts that contain disseminated magnetite. These rocks

contain very high FeO, Fe 20^, and TiOg. A pyritiferous sulphide

zone coincides with a strongly magnetic body which is located

13

between Line 600 E and Line 900 E. The magnetic contours and

profi-les of this magnetic body provide magnetic parameters.

The nearly vertical dinning body ( i.e. dipping steeply to the

south ? ) extends for approximately 300 meters, with an estimated

depth between 12 and 2? meters, length of approximately 220

meters, and a magnetic width between 50 and 120 meters.

The overall anomalous area represents a mafic lithological unit.

The strongly magnetic bodies of the anomalous area may represent

an iron-rich differentiate of the mafics and/or sulphide zones

hosted by sheared and altered mafic metavolcanics*

Anomaly E

This particular negative anomaly has not been fully detail

ed as the anomaly trends through the Canamax-Labmin claim group,

This anomaly is unique due to its strong, continuous negative

magnetism. This anomaly cross-cuts the stratigraphy and may re

present a structural linament, possibly a fault/shear zone.

A thin and magnetic lamprophyre dyke in the felsic to intermed

iate metavolcanics is recognized in the anomalous area. The neg

ative anomaly may represent swarm-like, thin magnetic dykes,oc

cupying a fault/shear zone.

The negative nature of this anomalous area and its spatial re

lationship with other mafic intrusive rocks is not fully under

stood at this time.

There are numerous other magnetic anomalies on the property.

These anomalies are generally smaller in strike length, have a

thinner magnetic 'width 1 , and show a slight to moderate magnetic

attraction,

Conclusions

The magnetic survey was successful in outlining lithological

units/horizons, structural linaments, and mineralized zones,

The high magnetic expression in the southeastern ( i.e.

Anomaly C ) and northeastern ( i.e. Anomaly D ) parts of the

property characterize the mafic lithology. The strongly sheared

felsic to intermediate metavolcanics characterize a strong, con

tinuous magnetic attraction in the western part of the property

( i.e. Anomaly A ). Shears and fault zones commonly associate

with these magnetic expressions,and are characterized by thin,

continuous magnetic linears and discontinuities and/or inflections

of lithological units. Anomaly E is a very good example of a cross

cutting fault/shear zone. The survey was also successful in outlin

ing a number of sulphide horizons that have a strong magnetic

attraction ( i.e. Anomaly B ). These zones are coincidental

to VLF-EM zones.

The correlation between contoured magnetic data and geologi

cal and VLF-EM data is the best way to interpret the magnetic

data. The interpretation of magnetic anomalous areas can be bet

ter understood from known and from the extrapolation of geologi

cal features.
