INTRODUCTION

F r o m June 15, 1970 to August 15, 1970 a 5 man team

of field personnel carr ied out a photogeological, geological

and intense surface prospecting program on the 'D' group

of claims owned by Fortune Channel Mines Ltd. and

located in the L i a r d Mining Division, €31-itish Columbia.

The period of field work represents 55 man days while

air photo interpretation represents 6 man days. This

report is a compilation of the data obtained from these

various work programs. The purpose of the programs

was to evaluate the economic potential of the property.

- GENERAL

The 'D' group of claims is situated in one of the most

active areas of mineral exploration in the province of

British Co!umbia. The property is located some 100

miles WSW of F o r t Nelson in the Churchil l Peak area,

a region which has a number of proven copper deposits.

A total of over 100 copper occurrences have been

located to date, including those of Churchil l Copper

Churchil l Copper Corp. L td . has a 1000 TPC' mill in

operation and nearby Davis Keays is progressing with

construction of a 1000 TPD mill, based on a feasibility

report recommendation. Both ore bodies are in the

range of 2,000,000 tons of proven ore grading 3% to 5%

copper.

Windermei-e Exploration Ltd.. adjacent to the subject

property, is presently continuing an exploration and eval-

uation program on the Bronson Vein, one of the company's

10 holdings in the ares.

Copperline Mines has discovered 3 veins within a width

of 100 feet. The ore grades from 1 % to 6% copper with

associated silver values. The company is carry ing out

a trenching program to further expose and assess vein

structures.

Witness posts were used in many instances to claim favour-

able areas which were , because of topography and climatic

conditions, inaccessible during the period of staking.

LOCATION AND ACCESS

The claim group' i s located some 100 air miles WSW from

F o r t Nelson, Bri t ish Columbia near Churchil l Peak. Co-

ordinates of the property are 58"151 N Latitude and 125O18'

W longitude. Usual access is by helicopter from either

Mile 442 o r Mile 392 on the Alaska Highway. At these

two points lodging can be obtained.

A n alternative route is offered via a secondary road branch-

ing from Mile 401, Ahpska Highway, to an airstr ip near the

mill site of Churchil l Copper Corp. Ltd. A helicopter can

be taken f rom the Churchil l a i r str ip to the property, a

distance of some 20 miles. Coppe-line Mines Ltd. plans

to improve the i r extension of the Churchil l road which wil l

shorten the air distance. Okanagan Helicopter CO. Ltd.

has a base located at the F o r t Nelson airport. Fly ing time

from F o r t Nelson to the property is approximately one hour

in Bel l 206A Jet R m g e r , 5 place turbina helicopter. It

should also be noted that a light plane airstrip could be

easily built and maintained on the glacial wash off the north

eastern corner of the property. The rocks here are

relatively small in s i r e and a 0 4 "Cat" would have no

trouble building an airstrip. The shaley glacial debris

forms a very solid base capable of supporting medium

weight aircraft of DC3 s i re equivalent.

CLIMATE

The climate of the area is sub-arctic. This climatic

belt is characterized by relatively short summers and

long cold d ry winters. January, the coldest month, has

a mean minimum temperature of 55O below zero while

July, the hottest month, has a mean monthly temperature

of 60' Fahrenheft wit4 maximum around 95O F. Freeze-

up commences in mid-Octob e r and break-up begins in

late Apr i l limiting the field season to just over 4 months.

I t is noteworthy that snow fell 3 times at an elevation of

5,000 feet during the month of July, 1970. These 3 inch

falls however, m.slted within a day. Precipitation ranges

from 12 to 20 inches and snow fall totals to 5 feet per year.

Timberline in the area ranges f rom 4500 leet to 5000 feet

ASL. Thus trees are confined to the low lying areas of

streams and glacial valleys. The Vegetation is mixed, with

alpine fir, balsam fir and spruce being domynant. Dwarf

birch is the principal shrub which inhabits the lower reaches

of talus slopes and washouts. Above timberline, alpine moss,

grass and f lowers grow on the more gentle slopes.

TOPOGRAPHY

The property lies in the western most, sub-province of the

Rocky Mountains physiographic belt, the Sentinel RdngeS.

This range trends NW to SE, extending from Muncho Lake

into Tuchodi Lake, a distance of 75 miles with a width of

up to 30 miles. The Sentinel Rringe terminates in the {I

west in Gataga R ive r which marks the limit of the Rocky

Mountain Rdnges. High peaks in the surrounding area are

ADVANCE GEOPHYSICS LIMITED

numerous. Chu-chill Peak, the highest, r ises to over

9000 feet ASL. Elevations 07 the property range from

4500 feet ASL to 8000 feet ASL. There is much evidence

of Pleistocene glaciation and some small hanging glaciers

still remain. Soms prominent characteristic glacial features

noted in the region were 'J-shaped valleys, cirques, aretes,

hanging valleys and many glacial sediments. Glaciotalus

debris fills most of the valley f loors, the lower slopes are

talus covered and the upper slopes are steep with many

vertical cliffs.

On the Fortune Channel Mines Ltd. property, glaciotalus

debris wash fills the central valley of the ID' block. A 30

foot wide, milky white, glacial stream ( A - 1 3 ) flows S W

through the wash. T w o tributaries (A-I30 and A-138)

of this main stream, one at each end of the property, flow

from glacier and snow filled cirques.

PHOTOGEOLOGY

An airphoto interpretation program was carr ied out in

conjunction with geologic mapping and surface prospecting.

The study searched for zones of weakness and dyke form-

ation as economic copper deposits are related to them.

i,

ADVANCE GEOPHYSICS L IMITED

Such zones were investigated and assessed in the field.

Air photograph interpretation is reliable due to the almost

entire absence of vegetation on the steep mountain sides

and the distinct lithologic expression of the various rock

units.

REGIONAL G E O L O G Y

All the rocks exposed in the Sentinel Rdnges are of

sedimentary origin except f o r the basic dykes which

intrude only the oldest ( Proterozoic) strata. The meta-

sedimentary sequence exposed trends N to N N W and

ranges in age from Late Precambrian to E a r l y Ordi-

vician. The Proterozoic units in the area consist of

thinly bedded, often slatey cleaved, medium to dark grey-

black, calcareous shales and siltstones. Minor fine

grained sandstone lenses are sometime present. These

strata are cut by grey diabase dykes, which average

about 15 feet thick but may exceed 5 0 feet widths in some

areas. Overlying these units are Paleozoic sediments of

E a r l y Cambrian Age. These are characterized by brown

weathering conglomerates, sandstones and shales with thick

lenses of impure limestone. These sediments are not cut

by dykes and strike approximately N to NNW with a

shallow westerly dip. They fr>rm an angular unconform-

ity with the underlying Proterozoic strata. U'lits younger

than L o w e r Cambrian were not exposed in the subject

areas. The Proterozoic strata in the region studied

consists of three sub-parallel zones with a general NNW

trend.

O i l y the western and central Proteroroic zones were

examined but i t is assumed that the eastern zone is similar.

The two zones were examined in varying detail with the

western one receiving most work . It was found to be over-

lain by unconformable Paleozoic sediments on the west and

bounded by a thrust fault on the east. T o the east of this

thrust fault Paleozoic sediments were again exposed and

noted to be unconformably overlying the Proterozoic sedi-

ments of the centre zone.

The three zones of Proterozoic sediments are characterized

by the existeqce of sub-parallel basic igneous dykes and

related quartz-carbonate veins, which cut them but not the

younger sediments. Tihe most western zone trends along

the W side of the Toad River and continues south through

the Fortune Channel property, and also Windermere's

I

Bronson property .

The centre zone contains the mines of Churchill Copper

Corp. and Davis K e a y s Mrneral Co . and also Copperline

Mines main property. This zone crosses the Alaska High-

way at Mile 436. The eastern zone was not examined bllt

is assumed to be similar.

The dykes have been noted to str ike in two directions,

northwest and northeast, with the northwesterly trend far

more common. On occasion, dyke intersections were

observed. These intrusions often have reported strike

lengths of over three miles. The dykes average 15 feet

wide and dip vertically o r steeply to the west. As mentioned

earl ier, the dykes cut only the Proterozoic and not the younger

sediments. The presence of dykes is the main criterion for

recognition of the favourable Proterozoic units in airphoto

studies and preliminary reconnaissance.

The dyke contact with the country rock is generally sharp

and there is little evidence of contact metamorphism. Rock

alteration from dyke ehlacement i s generally restricted to

those dyke contacts where shearing and brecciation are in

evidence. The wall rocks may become siliceous, talcose,

serpentinized and show calcite remobilization.

Of economyc im2ortance is the copper mineralization found

in quartz carbonate veins and vein systems which are

associated with the dykes. In these veins, the copper

mineral is usually chalcopyrite with minor bornite, secondary

malachite and azurite are seen in weathered surface zones. I

The carbonate in the mineralized veins is generally ankerite. ~

Although minor copper OccurrenCes have been noted in

lower Paleozoic strata, all major quartz-carbonate veins

are related to basic igneous dykes which only cut the

I ' I

~

Proterozoic units.

This fact was us'ed as a basis for efficient prospecting. !

The results of detailed prospecting on this basis showed

that all major dyke systems have related copper mineraliza-

tion although i t was often only in very sub-economic

occurrences. The dykes and vein systems have similar

attitudes which are constant in certain zones of the area

examined. ,

~

I

T h e dykes and veins fkpllow similar zones of weakness in

the sediments and are .approximately contemporaneous in

deposition with the dykes, perhaps predating the veins.

ADVANCE GEOPHYSICS L I M ~ T E D

- 11 -

The zones which were easily intruded by the dykes

also provided channelways for the copper bearing quartz

carbonate solutions. T h e more important deposits show

evidence of shearing and brecciation, indicating that the

dykes although not much older than the veins, probably

enhanced the channelways and thus indirectly localized the

major deposits.

The important deposits of the area are in shear zones

associated with dykes and therefore, likely persist to

considerable depth. The zones are observed to be

extremely variable in width over short distances. Thus

the search for length potential is the major factor in

exploration and length potential is far more significant

then the width in evaluating any particular showing.

P R O P E R T Y GEOLOGY

The ID1 block of mineral claims lies in a highly favour-

able geologic environment. All the sediments recorded

were of Proterozoic a e and mainly of calcareous dark

grey siltstone and shale. Although glacial debris covers

one quarter of the property, sufficient geologic data was

obtained to extrapolate the geology through this glacial area

The beds are thinly laminated and are fine grained. The

strata str ike N to S and dip gently to the W. Dip angles

ranged from 5' to a maximbdm of 30' in the westerly

direction. The sediments were siliceous with calcareous

cementing in most parts of the property. N o evidence of

fossilization was encountered while traversing the claims.

No less than 30 basic dykes averaging 15 feet in width

cut through the property. They have a strike of N N W

except in the area of claims D 84 and D 82 where there

are three dykes str iking W. These E-W dykes take the

form of stringers off a major NNW striking dyke and

follow a structural weakness in the sediments. The dykes

dip steeply west, on the average about 85'. These

igneous intrusions are much more resistant to weathering

than the surrounding calcareous sediments and thus are

easily recognizable by their rel ief. Augite and plagio-

clase make up the main portions of the diabase dykes

composition. Biotite, pyri te and magnetite are also

evidenced in varying amounts. In places, weathering of

these i ron minerals givks a distinctive r e d brown staining

to the dyke rock. Epidote, an alteration mineral, was

common to the dykes in the areas of shearing.

Several quartz-carbonate veins are located on the property.

T w o unmineralized ankerite-quartz veins of very solid

structure and fair width are found o n D 48 and D 88.

Although these veins are in close proximity to dykes,

their vuggy and well crystallized appearance indicates a

lack of shearing subseq uent to the formation of these veins.

The first is vertical and strikes at 340°. Its dimensions

are 2 feet in width with an exposed length of 40 feet. The

second unmineralized vein lying on D 88 has a very per-

sistent length of 1000 feet and 5 feet width. It strikes NNE

and is vertical.

T w o separate chalcopyrite mineralized veins are located

in the cirque at the S end of the property. They lie on

claim D 81 and D 86 respectively. The f irst at an eleva-

tion of 5900 feet, is a banded quartz-carbonate veinlet with

minor ankerite. The veinlet strikes N-S and cuts through

very basic dyke rock. I t is 6 inches wide on the face of

the dyke and pinches out at both ends after 20 feet. High-

grade chalcopyrite in blebs was consistent over this length.

Malachite is found as kecondary mineralization.

estimate of the grade is 10% copper. The dyke has been

sheared in this region and parts have been altered to epidote.

Visual

This veinlet takes the form of a post dyke fracture filling.

The second vein lying on claim G 86 is larger than the

first. Th is quartz-carbonate vein located at 6000 feet is

very close to vertical and strikes NNW. I t is 3 feet wide

and exposed for 30 feet. A definite length could not be

established as heavy talus covers much of the slope.

Although chalcopyrite is consistent as small blebs through-

out, the vein is of much lower grade than the first. A

visual estimate of grade is up to 1% copper in places.

Malachite is again found as secondary m;neralization.

However, with the greater width and evidence of shearing,

this vein h a s a fa r greater chance of having a persistent

depth. The vein lies between schistose grey shale and a

15 feet wide dyke. The shale has been reheated and r e -

cemented and is heavily fractured. Kaoliniration is evident

along these planes. T h e NNW striking dyke is mineralized

with disseminated pyrite.

Chalcopyrite in rounded quartz float was discovered in the

stream bed flowing from the hanging glacier at the NE end

of the property. Trahing the float located 3 vein 1500 feet

west of the property lcmits and on staked ground. This vein

is visually estimated to be lower grade copper than the float

indicated.

S U M M A R Y

The 104 claims of Fortune Channel Mines L td . arelocated

in an area of known copper vein properties such as Winder-

mere Exploration Ltd. , Churchil l Copper Corp, Davis-Keays

Mining Co. and Copperline Mines. Structurally, the property

is located along a Proterozoic meta-sedimentary fault block

trending NNE. The formations within this block strike N-S

and dip gently to the W. The sediments are relatively un-

folded shales, mudstones and argillites which give good

depth potential to any vein system.

The mineral deposits of the area are all of the same general

type, that is, quartz-carbonate f issure veins which c a r r y

scattered and bleby copper in the form of chalcopyrite. All

the mine making copper mineralization occurs in veins in

Proterozoic sediments. In almost all instances, green-brown

diabase dykes attend or are intimately related to the veins.

Thus, the property is in an area of highly positive economic

potential becaclse the claims area covers solely Proterozoic

formations with at leash twenty dykes trending NNW through

them. F o u r major quartz-carbonate veins were located, two

being mineralized with blebs of chalcopyrite and secondary

RECOMMENDATIONS

At present, no economic sized ore zones have been discovered

on the property. Work programs have been suspended. P r i o r

to the expiry date of the claims i t is recommended that a re -

appraisal of results be made, reviewing the work programs

carr ied out on surrounding properties. This information may

delineate areas on the subject property which warrant further

investigation.
