INTRODUCTION

At the instruction of Robert Ross Dion, the writer set out to

perform a fracture density analysis on the PERK group of min-

e r a l claims. The ressults of this work a r e summarized in the

present report for assessment purposes.

The writer commissioned D.A. Chapman to annotate the vertical

colour airphotographs, perform the point-count of the isostatic

t races , ca r ry out the relative-density calculations, and provide

the plan of relative density isogradients, in addition to inter-

preting the indicated shear tension faul t zones.

PROPERTY HOLDINGS

This assessment report supports assessment work requirements

for one year on the PERK group of mineral claims. The colour - airphoto stereopair which was employed for th i s project inclu-

ded more than the subject claims, however the total area i s

here shown a s gold showings a re known to occur on the north

flanks of the Perkins Peak massif, off the present claim group.

LOCATION 8 ACCESS

51 48'N 125 05'W NTS: 92N14E

The PERK GROUP i s centered around Perkins Peak which l ies

about 17 km southwest of Kleena Kleene, B.C., about 224 km

west of Williams Lake, B.C. The property can be reached

via about 50 km of 4x4 road s tar t ing s tar t ing from the Williams

Lake-Bella Coola highway (256 km west of Williams Lake) a t

a point about 2.5 km west of Chilanko Lodge on One Eye Lake.

Access on the property i s by helicopter, and mountain climbing,

although a tote-road exists up Chromium creek to the Crown

Grants southeast of the PERK GROUP, and another one supplies

access to the gold property to the north of the group.

PHYSIOGRAPHY. VEGETATION. CLIMATE

Perkins Peak r ises to 2820 mASL a t the western edge of the In-

terior Plateau defining the beginning of the Coast Range. This

locality i s thus also the interface between the moist coastal

and the d ry interior climates. Precipitation in the form of

snow remains almost perennially on the northern slopes. Vege-

tation i s scarce.

HISTORY

A gold-silver property on the northeastern flanks of Perkins

Peak has been known by various names over the years , the

most common being: Mountain Boss. The f i rs t mention of th i s

i s in the 1916 Annual Report of the British Columbia Depart-

ment of Mines, and references follow for the years since then.

The present writer inspected the gold showings in August of

The Crown Grants a t the head of Chromium Creek were staked

for their iron content a s explained in the 1922 BCDM Annual

Report, page G218.

"...The group of claims occupies the whole of the glacial cirque at the head of Chromium creek and the boundaries extend down that creek on both banks for a very considerable distance,..The entire group of claims is about 1,000 feet above timber-line, which fact led to the construct- ion of a large rock cabin for a mine camp... ... It is very difficult to form any opinion as to the extent of the deposits of haematite-iron ore, because, although several open-cuts have been made across the mineralized zone, none of these were deep enough to expose bed-rock... ... The only development-work besides the open-cuts is a crosscut adit described by Galloway (1916) as being 600 feet long, but which in 1921 could not be examined because its caved condition made it impossible to enter... ... Conclusions- ... but that the evidences of mineralization are so pronounced and cover such a large area, not being merely confined to Chromium Creek deposits, as to make the section quite attractive to prospectors for other minerals than iron ore. In the event of other discoveries being made in the zone of contact represented in the section, such might develop into mines having sufficient commercial value to warrant the improvement of the transportation facilities to a point where the iron ore could be mined profitably ..."

Tile writer i s unaware of any further exploratory work in the area of the claims, except for the possible overlap of ae r i a l I

surveys done on neighbouring properties.

GENERAL GEOLOGY

Appendix B i s a plan showing the generalized geology of the

area.

The claimed area i s underlain [Tipper, 19681 by a sequence

designated by rock Units 12 and 13, intruded by Coast Plutonic

rocks (Unit B).

Unit 13, andesitic and basalt ic breccia and tuff, with minor

shale, greywacke and conglomerate, i s underlain by Unit 12,

siltstone, greywacke and conglomerate.

The gold-silver showings of the Mountain Boss property occur

within Unit 12 which locally consists of light coloured quartzite,

and black or dark grey argillaceous sediments, some of which

are limy. The att i tude of these sediments i s about E-W with

southward dip of 45 degrees. Basic dikes cut the sediments,

and light coloured dikes and thick s i l ls occur on other portions

of the property. Quartz lenses follow along shearing which

generally trends parallel to the bedding of the sediments. Some

quartz veins also cut the bedding a t i r regular attitudes. Sili-

fication i s widespread. Calcite occurs within the quartz and

silicified wall rock.

Arsenopyrite-pyrite and some chalcopyrite associated with

quartz occupy fractures which dip steeply to the north within

the silicified quartzite sedimentary bed which dips south strik-

ing east.

The hematite showings on Chromium creek are described in the

1922 A R of the BCDM a s follows:

" ... Geology- ... A considerable portion of these slides is made up of float iron ore in pieces varying in size from gravel to large lumps. .. The country-rock in the vicinity of the group of claims is chiefly argillite, which has in many places been intruded by the granitic rocks of the Coast Range. The zone

of contact between the granitic rocks and the older sedi- mentaries and volcanics is fairly well defined in the locality of the occurrence of the iron-ore deposits which Galloway (1916) considers are of contact-metamorphic ori- gin.. ."

A I RPHOTO

FRACTURE DENSITY

ANALYSIS

PURPOSE

Colour, vert ical airphotographs provide valuable information

in many ways to the explorationist, one of which derives from

the stereoscopic study of s t ra ight , and/or arcuate lineations,

caused by stress-relief ruptures within the bedrock a t the sur-

face of the ear th . I t has been postulated tha t the relative

density per unit a rea of these lineations i s an indication of

the open-ness of the rocks to the influx of mineralizing solu-

tions. Hence, the premise tha t the study of fracture density

may give the exploration geologist another tool to be used in

defining exploration targets .

POSSIBILITIES OF THE METHOD

Large-volume "porphyry copper" type deposits tend to include

ore mineral disseminations in stockwork fractures within grani-

t ic , volcanic, or other metamorphosed rocks a t , or near intrus- I

ive contacts of grani t ic bodies. Because ore-metallization ap-

pears to be related to rock-type contacts and changes i n frac-

EARE EX E N G I N E E R I N G m i s s i o n b c

PERK Gp:92N14E:CARIBOO:AIRPHOTO F R A C T U R E ANALYSIS

continued: POSSIBILITIES OF THE METHOD

ture density, th is study was undertaken to attempt outlining

of rock types, and pinpointing anomalously fractured zones.

This method, when used in conjunction with other information,

such a s geophysics or geology, can be utilized to outline a reas

of interest with minor unit-area expense.

LIMITATION OF THE METHOD

Heavy snow cover and overburden tend to obscure the finer

fracture detai ls , although major trends will show through most

surficial deposits.

Rock types fracture in different patterns, and each has a spec-

i a l signature. When lithologic boundaries a r e unknown to the

interpreter then there may be difficulty i n differentiation bet-

ween fracture density increases caused by anomalous tectonic

action within a homogeneous lithologic uni t , or by simply chan-

ges i n rock type. In the f i rs t case, addit ional fracturing may

be of interest , while in the second instance, a non-mineralized

rock body may exhibit more bdding, schistosity, and joints,

without enhancement of the ore-hosting process.

Although fracture density anomlies could be assumed to always

indicate zones more worthy of interest to the explorationist,

i t must be realized tha t metallization of favourable host rocks

has been known to occur i n moderately-fractured rocks.

In the present study only apparently vertical fractures have

been annotated by D. A. Chapman. Furthermore, their on-strike

extrapolations have been connected to form semi-continuous lin- I

eations.

PERK Gp:92Nl4E:CARIBOO:AIRPHOTO FRACTURE AWALYSIS

METHOD OF ANALYSIS

The following ver t ical , colour airphotographs, obtainable from

the Map Division, Parliament Buildings, Victoria, B. C., were

chosen to provide stereoscopic coverage of the a rea required:

Colour-30BCC281: # 101 & #I02

Flown: July 4, 1981

A plastic overlay was attached to #I01 and marked in such

a way tha t reorientation can be done accurately, using Perkins

Peak, a road, and two lakes a s tie-points. The scale on the

airphoto overlay var ies with distance from the center, and es-

pecially with camera-object distance. Hence la rge variation

in scale i s to be expected between the peaks and valleys.

POINT COUNT

In order to facil i tate quantifying this information a method

has been devised [Tait Blanchet, D.A. Chapman] whereby the

airphoto overlays ( annotated with the traced lineaments) a r e

divided by an orthogonal g r id , - with 1 cm dimensions in th i s

par t icular case. The gr id i s carr ied on a separate overlay.

A moveable circle template, with diameter 1 cm, i s then cen-

tered on each of the g r id points, and the quantizing of the

fracture information commences. Following i s the method of

valuating the lineations:

A l l t raced fracture segments a r e counted:

a ) fractures tha t cross the circumference

of the circle once a r e given one point. - b ) . . .twice a r e given two points. - c ) . . . not crossing a re given 1/3 points. -



continued : POINT COUNT

The result of quantizing the visible isostatic traces i s display-

ed a t ' un i t area sample centers ' on the Appendix plan desig-

nated: Sheet 2 of 4.

RELATIVE DENSITY ESTIMATE

The relative density estimate of 'visible fracture/fault pat terns '

observed, i s shown a s Appendix Sheet 3 of 4.

This i s a plan depicting arithmetically-obtained interpolated

mean values observed between surrounding unit area samples.

This information i s akin to the taking of the f i rs t derivative

of the point count information, and a s such i s ' f i l tered ' da ta .

RELATIVE DENSITY ISOGRADIENT

The process of contouring equal-value locations on the sur-

vey plan provides the isogradient of the relative density of

visible fracture/fault pat terns observed on the subject airphoto.

This information i s here shown a s Appendix Sheet 4 of 4.

INDICATED SHEAR-TENSION FAULT ZONES

'probable tension/shear fau l t s ' a s interpreted from the da ta

by M r . Chapman.

NEAREX E N G I N E E R I N G m i s s i o n bc


RESULTS OF STUDY

The relative density isogradient i s shown a s contoured a reas

of 'h igh ' and 'low' value zones.

I t i s apparent tha t immediately east of Perkins Peak i s the

locality of a large ' h igh ' . This i s further circumscribed by

arcuate lineations. Several ' b i r d ' s eye' high areas dot the

remaining survey area.

Indicated shear tension faul t zones flank most of these 'h igh '

a reas , and trend north-westerly and north-easterly, the la t te r

direction showing prominence i n being continuous through the

subject a rea .

DISCUSSION OF RESULTS

The geologic map, Appendix "A", shows tha t the bedding con-

tact between Units 12 & 13 passess through the property in an

almost E-W direction, skewing somewhat north-easterly . This

bedding att i tude would approximately disect the angle between

the ' indicated shear tension faul t zones ' . Location of intrusive plugs, and contact metamorphic relation-

ships i s not shown on th i s general geological presentation.

This method of quantizing fracture density determinations has

been effectively utilized to outline those a r eas exhibiting

higher-than-average (re la t ive to the survey a r e a ) changes in

fracture density. I t allows examination of stress-strain re-

lated patterns of the rocks underlying a large a r ea , a t very

reasonable cost.



CONCLUSIONS

1) The ground immediately north of the end of the mine road

shown on Sheets 1-4, i s spotted with several open cuts.

These relate to the exploration activity on the Crown Grants

a t the head of Chrome creek, which reportedly was for he-

matite a t a metamorphic contact.

The zone up-slope from these open cuts shows up a s a small-

order 'h igh ' on Sheet 4/4. This smaller high coalesces

with the large-area, large-order 'h igh ' on the south-east

flank of Perkins Peak.

2 ) The above-mentioned zone futhermore occurs on, or near the

through-going , north-east trending indicated shear tension

faul t zone shown on Overlay Sheet 4. A north-westerly

trending indicated faul t zone passes northwesterly towards

Perkins Peak from th is a rea .

The recommendations by D.A. Chapman, a s shown in the ap-

pendix, are:

"Prospecting t raverses should be along the preferred shear

zones. These deep-seated faul ts offer the most l ikely zones

where mineralization will occur.

a ) Geological prospecting should be supported with rock geo-

chemistry.

b ) A VLF-EM unit should be used a t in tervals across the

s t r ike in conjunction with soil geochemistry in a r eas where

overburden exists.

Further airborne work over the claim a rea , using low level

magnetometer-VLF-EM geophysical surveys, could be perform-

ed." '

RECOMMENDATIONS

As t-he claimed area includes Perkins Peak, work on the prop-

er ty must be performed by personnel skilled in mountaineering.

In addition to prospecting and geological sampling, soil and

s i l t sampling in creeks, and a t the base of scree sl ides, es-

specially along the contact, and fault zones, i s recommended.

Helicopter-borne electromagnetic, and magnetic surveys now

utilizing sophisticated, state-of-the-art technology, can be uti-

lized in th i s a r ea , especially where contact zones, and conduc-

tive veins could be suspected.

Two sectors of the claimed area appear to be of interest under

the parameters of this study. They appear a s co-incident

'h igh ' values, a s shown on Figure , with a reas within

arcuate t races , a s shown on Appendix Sheet 1 of 4.

The f i rs t of these interesting a reas l ies just easterly of Per-

kins Peak, while the other shows up a s a smaller size 'h igh '

located southwest of the isolated small lake, and trending

northerly towards the la rger lake.

These two areas could serve a s a focus of exploration, while

the remainder of the property i s prospected.

RECOMMENDAT IONS

1) PROSPECTING TRAVERSES SHOULD BE ALONG THE PRE-

OFFER THE MOST LIKELY ZONES WHERE MINERALIZA-

TION WILL OCCUR.

a GEOLOGICAL PROSPECTING SHOULD BE SUPPORTED

WITH ROCK GEOCHEMISTRY.

b) A VLF-EM UNIT SHOULD BE USED AT INTERVALS A-

CROSS THE STRIKE IN CONJUNCTION WITH SOIL GEO-

CHEMISTRY IN AREAS WHERE OVERBURDEN EXISTS.

2 ) FURTHER AIRBORNE WORK OF THE CLAIM AREA USING
