DIAMOND DRILLING . on the

OLD FORT PROPERTY

INTRODUCTION L

The mineral claims referred to in this report are located

on Babine Lake, in central British Columbia, approximately 40

miles northeast of of the town of Smithers.

A program of geophysics, geochem and diamond drilling

was completed on certain of these claims to determine the cause

of a large induced polarization anomaly outlined during an earlier

geophysical survey. The work was carried out during the period

of May 6, 1974 to June 15, 1974.

The I.P. survey was conducted under the general supervision

of J.T.Walker, Geophysicist. The Geochemical survey was conducted

under the general supervision of J.D.Knauer, ~eologist/~eochemist,

The general geology and Diamond Drilling was conducted under the

general supervision of G.Belik, Geologist.

LOCATIONAND ACCESS

The claims, comprising what is known as the Old Fort Property,

are situated on the southeast flank of Old Fort Mountain, in the

0 0 Babine Lake area, at approximately 55 08'N, 126 22'W; this is some

40 miles northeast of Smithers and 155 miles northwest of Prince

George.

Access from Smithers is by either air (float plane,

helicopter) or by road to Smithers Landing or Topley Landing and

+ thence by boat. On the property, a rough bulldozer road leads

from ~abine Lake to the main showings and the drill sites, ? 1

L

Transportation on Babine Lake for the diamond drill and

ancillary equipment was provided by a tug and barge rented from* L

Northwood Pulp and Timber, Limited.

CLAIMS AND OWNEiRSHIP

The recorded owner of the claims is Wesfrob Mines Limited,

The claims are:

Claim Name Record No,

DDT 5 - 14 inclusive 31262 - 31271 inclusive DDT 19 - 40 inclusive 31276 - 31297 inclusive OFF 1 - 8 i.nolusive 31298 - 31305 inclusive OFF 15 - 18 inclusive 31312 - 31315 inclusive RAID 1 - 14 inclusive 31316 - 31329 inclusive

GEOLOGY

The Old Fort property is underlain largely by sedimentary

rocks of the Jurassic Hazelton Group. These consist of greywacke,

argillite and siltstone, with the latter two often containing pyrite

and abundant carbonaceous material, In the vicinity of the RAID 11

and OFF 6 mineral claims, the sediments are intruded by a small

stock of quartz diorite, approximately 2400 feet in diameter, which

encloses a much smaller, elongated core of biotite quartz monzonite.

Radiating outwards from the core are several dyke-like bodies of

biotite feldspar prophyry. A ho-rnfels zone is develop6d in the

sediments and extends westward from the stock towards the summit of

Old Fort Mountain. Chalcopyrite, sparse molybdenite and rare bornite

occur as disseminations, fracture fillings and replacements of mafic

minerals in three small, discontinuous, low-grade zones in the L,

quartz diorite.

INDUCED POLARIZATION and

RESISTIVITY SURVEY 'L

In t roduc t ion

The Induced Po la r iza t ion and R e s i s t i v i t y Survey was ca r r i ed

ou t us ing va r i ab l e frequency I . P . equipment owned by Noranda

Explorat ion Company Limited and manufactured by Sabre E lec t ron ic

Instruments Limited, Burnaby, B.C. A c r e w of four Noranda employees

conducted t h e survey under pa r ty ch ie f Lyndon Bradish, Geophysicist,

during t h e period June 18 - June 22, 1974.

The purpose of t h e survey was t o extend southward and

eastward, an I . P . survey c a r r i e d ou t by Falconbridge Nickel Mines

Limited, during 1971. Seven l i n e s , spaced a t 800 f e e t , were surveyed

f o r a t o t a l of 12.6 miles.

Method

Throughout t h e survey, a dipole,-dipole e lec t rode configuratior

was employed. The d ipole length was 400 f e e t and t h e d ipole spacing

was 400 f e e t (x=400; n = l ) . The ellectrode a r ray and instruments

were moved along t h e survey l i n e s with readings being taken a t 400

f o o t i n t e r v a l s , A t each s t a t i o n "set-up" t h e following measurements

a r e made and recorded:

(1) Current i n t e n s i t y applied t o t h e ground a t t h e cu r r en t e lec t rodes (measured i n mil l iamperes) .

(2) p o t e n t i a l developed between p o t e n t i a l e l ec t rodes (measured i n mil l iamperes) .

laboratory, located a t 1050 Davie S t r e e t , Vancouver 5 , B .C. ,.Analyst

was Bob Mower.

Samplinq Methods

a. S o i l s

Samples were obtained by digging holes with a shovel t

a depth where the v i s i b l e C Horizon, whenever poss ib le , was

encountered. The B and C Horizons were sampled a t a l l

loca t ions where they w e r e v i s i b l e . Where it was not poss ib le

t o ob ta in both the B and C Horizons, the b e s t sample was

taken depending on what was encountered a t t h a t p a r t i c u l a r

sample s i t e . A number of p r o f i l e s w e r e taken, s ca t t e r ed

throughout t h e g r i d system, where a l l v i s i b l e horizons were

sampled.

The samples were placed i n "Hi Wet Strength Kraf t

3$"x6 1/8" Open End" envelopes and the g r i d s t a t i o n was

marked on the envelopes with i nde l ib l e f e l t pen, S o i l samples

were taken a t 400 foo t i n t e r v a l s along the g r i d l i ne s .

b . Stream Sediments

Samples were obtained by co l l ec t ing the f i n e s t t ranspor ted

mate r ia l ava i lab le - preferably s i l t , from the cen t re por t ion

of t he creek, away from the creek banks. The samples w e r e

L placed i n "Hi Wet Strength 3$"x6 1/8" Open End" envelopes

and the g r id locat ion marked on the envelopes with i nde l ib l e P

&

f e l t pen. Stream sediments were taken, wherever' poss ib le ,

when a c reek was encountered along t h e g r i d l i n e s .

Laboratory Determination Methods

a . S o i l s

The samples a r e f i r s t placed i n a drying cab ine t f o r a

pe r iod of 24 t o 48 hours. The sample m a t e r i a l i s then

screened and s i f t e d t o o b t a i n a -80 mesh f r a c t i o n .

The determinat ion procedure f o r t o t a l copper, z i n c and

molybdenum i s a s follows:

0.200 grams of t h e -80 mesh m a t e r i a l i s d iges ted i n 2 m l

of HC104 and 0.5 m l of HN03 f o r approximately four hours.

Following d i g e s t i o n , each sample i s d i l u t e d t o 5 m l wi th

demineralized H20. A Varian Techtron Model AA-5 Atomic

Absorption Spectrophotorneter was used t o determine t h e p a r t s

p e r m i l l i o n copper, z i n c and molybdenum content i n each sample,

b. Stream Sediments

The samples a r e f i r s t placed i n a dry ing c a b i n e t f o r a

pe r iod of 24 t o 48 hours. The sample m a t e r i a l i s then screened

and s i f t e d t o o b t a i n a -80 mesh f r a c t i o n .

The de terminat ion procedure f o r so lub le copper and z i n c

i s a s foll.ows:

0.200 grams of t h e -80 mesh m a t e r i a l i s d iges ted wi th 5 m l

of 0.5 NHCl t o a b o i l f o r 25 minutes. The sample i s brought

back t o 5 m l . w i th 0.5 NHCl a f t e r cool ing. A Varian Techtron

Model AA-5 Atomic Absorption Spectrophotometer was used t o 1

determine t h e p a r t s per m i l l i o n copper and z i n c con ten t i n : L

each sample.

The determination procedure for t o t a l copper, zinc and "

molybdenum is a s follows:

0.200 grams of the -80 mesh material i s digested i n 2

of HC104 and 0.5 m l of RN03 for approximately four hours.

Following digestion, each sample i s d i lu ted t o 5 m l with

demineralized HzO. A Varian Techtron Model AA-5 Atomic

Absorption Spectrophotometer was used t o determine the

p a r t s per million molybdenum content i n each sample.

The theory of the Atomic Absorption Spectrophotometer i s

f u l l y described i n the l i t e r a t u r e and w i l l not be described

i n the report .

Presentation of Results

Results of the s o i l and stream sediment surveys a re presented

i n Drawing Nos. GC1 and GC2 of t h i s report . These a r e plan maps of

a sca le 1"=4001 which show copper, molybdenum and zinc i n pa r t s per

million. Anomalous values fo r each element are indicated as shown

i n the legend on Drawings Nos. G C 1 and GC2.

Discussion of Results

Overburden covering the area of t h i s survey is primarily

of g l a c i a l or ig in consist ing of boulder t i l l s and clays. The known

depth of the northwest portion of the gr id averages around 35 f e e t

between scat tered outcrops. From a l l indications the overburden

would appear t o increase i n depth with the decrease i n elevation

t o the southeast.

The r e s u l t s f o r copper, z inc and mol.ybdenum values i n t h e

t s o i l s and stream sediments a r e a s follows:

1. The major i ty of t h e copper and z inc values f a l l wi th in background

ranges. The few s c a t t e r e d values above threshold show no s igni f i .cant

Logging of the core was carr ied out by G-Belik during $he L

period June 6-7, 11-14, 1974 f o r a t o t a l of 6 days.

The core was placed i n wooden boxes with a capacity of 25

f ee t ; these have been marked with the hole number and the contained

footage and are stored i n racks a t the "Bible Camp", the Noranda

campsite located on DDT 1 2 .

CONCLUSIONS

Economic copper mineralization was not observed i n any of

the core obtained from the s i x holes. It i s f e l t t h a t the induced

polar izat ion anomaly may be adequately explained by the presence

of the graphi t ic material noted i n varying amounts i n tk sediments

intersected i n a11 holes and by the sulphides (pyri te , minor chal-

copyrite and pyrrhot i te) which loca l ly comprise up t o 7% of the -

core.
