SUMMARY, CONCLUSIONS AND RECOMMENDATIONS

The t h i r t y - o n e Esther claims l i e t h i r t y m i l e s north of

P r i n c e t o n i n the M i s s e z u l a Lake area. They are e a s i l y a c c e s s i b l e by

a good g r a v e l road up Summers Creek V a l l e y from the I r i n c e t o n - M e r r i t t

Highway.

The area i s u n d e r l a i n by N i c o l a Group v o l c a n i c s which

are f a r from homogeneous. I n the immediate v i c i n i t y of the Shamrock

prospect, which l i e s w i t h i n the Esther c l a i m s , the rock i s medium-

grained f e l d s p a r porphyry which has been i n t e r p r e t e d as being a v o l ­

c anic f l o w b r e c c i a . To the e a s t , south and west are f i n e - g r a i n e d ,

dark green andesites c o n t a i n i n g disseminated sulphides.

A m i n e r a l i z e d f r a c t u r e zone that s t r i k e s n o r t h e a s t e r l y

can be f o l l o w e d along s t r i k e i n three trenches f o r about eighty f e e t .

Old r e p o r t s mention s i x trenches that extend the zone f o r 250' but

some of these are caved. The f r a c t u r e zone measures up to 25' i n width

but m i n e r a l i z a t i o n i s confined to about 5 !-18'.

The i n t e n s i t y of the f r a c t u r i n g and the amount of

m i n e r a l i z a t i o n i s impressive. The f a c t that the prospect l i e s c l o s e

to thoroughgoing, n o r t h e r l y - s t r i k i n g f a u l t s that can be p r o j e c t e d

southward to the Copper Mountain area cannot be overlooked, although

t h i s i s no guarantee that s i m i l a r d e p o s i t s w i l l be discovered. No

i n t r u s i v e s s i m i l a r i n nature to the Copper Mountain i n t r u s i v e s have

been seen along t h i s f a u l t b e l t .

Recently taken chip samples i n d i c a t e that the p r e s e n t l y

v i s i b l e m i n e r a l i z a t i o n averages 1.63% Cu across 11.6'. Although

c h a l c o c i t e i s the p r i n c i p a l m i n e r a l , disseminated c h a l c o p y r i t e was

seen up to 250' to the northeast o f the trenches.

From ten samples taken by the w r i t e r f o r 900 1 across

the mineral zone, s o i l sampling would appear to be an e f f e c t i v e

method of o u t l i n i n g zones of i n t e r e s t . The property warrants ex­

p l o r a t i o n and i t i s recommended that topographic mapping, p r o s p e c t i n g ,

geologic mapping, s o i l sampling, EM surveying and diamond d r i l l i n g

be c a r r i e d out. Estimated cost of t h i s program i s $20,000.

A f u r t h e r $40,000 should be provided to c a r r y on

a d d i t i o n a l diamond d r i l l i n g and t r e n c h i n g .

SCOPS

On J u l y 27th and 28th the mineral showings on the

Esther claims near M i s s e z u l a Lake were examined and the region geo­

l o g i c a l l y mapped. This work was done by the w r i t e r accompanied by

Mr. JY'J. Murton.

LOCATION AMD ACCESS

The Esther claims l i e t h i r t y m i l e s north of r r i n c e t o n ,

B r i t i s h Columbia, at the south end of M i s s e z u l a Lake. Access i s by

good g r a v e l road from the .crinceton-Merritt Highway f o l l o w i n g the

Summers Creek V a l l e y f o r eighteen m i l e s .

E l e v a t i o n i s about 3000'; topography i s r e l a t i v e l y

steep and the timber growth moderate.

rRQr'ERTY AND Ov/NERSHIP

The t h i r t y - o n e Esther claims are owned j o i n t l y by

E. G a r r i s o n , Broorafield and W, Shropshire of P r i n c e t o n , B r i t i s h

Columbia. The c l a i m group i s p r e s e n t l y under o p t i o n to D e l k i r k Mining

L t d .

HISTORY

Although the area was p r i m a r i l y a p l a c e r mining r e g i o n ,

copper occurrences i n the rrinceton-Aspen Grove area are common. The

Esther claims cover a showing that was formerly known as the Shamrock,

In 1929 i t was reported that the m i n e r a l i z e d zone could be followed

f o r 1500 f e e t . S i x open cuts explored the zone and i n 1929 a small

shipment was made which i s reported to have c a r r i e d 5.78% copper.

L i t t l e i s known regarding more recent work on the

property but i t i s known that diamond d r i l l i n g was c a r r i e d out a few

years ago. No records concerning d r i l l hole l o c a t i o n s or r e s u l t s are

p r e s e n t l y a v a i l a b l e .

GEOLOGY AND MINERALIZATION

For f o r t y m i l e s north from Copper Mountain a zone

occurs along which copper prospects are numerous. I n the Aspen Grove

area c e r t a i n showings are i n o r c l o s e to lar g e g r a n i t i c bodies and

probably are r e l a t e d to them. Other d e p o s i t s , i n c l u d i n g the one under

c o n s i d e r a t i o n , occur i n f r a c t u r e s and as disseminated g r a i n s of chalco

p y r i t e , p y r i t e , b o r n i t e and c h a l c o c i t e w i t h i n N i c o l a v o l c a n i c rocks

of T r i a s s i c age. No i n t r u s i v e rocks are known to be r e l a t e d to them

and the only t h i n g they have i n common seems to be t h e i r occurrence

along the trend of f a u l t s up A l l i s o n V a l l e y and Summers Creek.

The Esther showing i s u n d e r l a i n by a r a t h e r coarse­

grained r e d d i s h rock c o n t a i n i n g rounded fragments of f e l d s p a r porphyry.

T h i s rock has been i n t e r p r e t e d as a r a t h e r unusual flow b r e c c i a .

To the east and southeast of the mineral showing the N i c o l a v o l c a n i c s

are composed of p u r p l i s h b a s a l t s and medium-green andesites.

The r e d d i s h flow b r e c c i a i s i n t e r s e c t e d by a north­

e a s t e r l y t r e n d i n g f r a c t u r e zone which i s m i n e r a l i z e d w i t h c h a l c o c i t e

and f i n e l y disseminated c h a l c o p y r i t e . The m i n e r a l i z e d bands w i t h i n

the f r a c t u r e zone are a s s o c i a t e d w i t h c a l c i t e s t r i n g e r s which trend

e i t h e r e a s t e r l y or n o r t h e r l y .

Although o l d records show that the zone was t r a c e a b l e

f o r 25C 1 i n s i x trenches, only three trenches are p r e s e n t l y a c c e s s i b l e

and these show the mineral zone to extend over a s t r i k e length of

80'. Disseminated c h a l c o p y r i t e was observed about 250' to the north­

east i n s i m i l a r rock type.

During the examination, 28 c h i p samples were taken

i n the three p r i n c i p a l trenches. R e s u l t s are as f o l l o w s :
