FIELD PROGRAM

In t roduc t ion

The program conducted on t h e claim group during August, 1974, was designed t o f u r t h e r evaluate the economic p o t e n t i a l of lead-zinc- copper mineral occurrences i n t h e Stone and Dunedin formations. On t h e b a s i s of r e s u l t s from the 1973 exp lo ra t ion program s p e c i f i c a reas , s e l e c t e d by Aquitaine Company of Canada Limited w e r e covered by geochemical s o i l and t a l u s sampling and prospecting. S p e c i f i c mineral occurrences were geologica l ly mapped i n d e t a i l , and where phys ica l ly p o s s i b l e , sampled.

Geochemical S o i l and Talus Sampling

a On t h e a r e a se lec ted on which d e t a i l e d geochemical s o i l sampling was conducted, a chain and compass g r i d w a s l a i d o u t wi th c ross l i n e s spaced a t 200 f o o t i n t e r v a l s and o r i en ted approximately normal t o t h e s t r i k e of t h e underlying formations. S o i l samples were co l l ec ted a t 100 f o o t i n t e r v a l s a t depths of from 12 t o 24 inches us ing a prospect ing grub hoe and deposi ted i n c l o t h o r k r a f t paper bags t h a t were then l a b e l l e d according t o claim group, sample number, and g r i d co-ordinate. For t h e purpose of achieving more p r e c i s e hor izon ta l c o n t r o l , t h e g r id and corresponding s o i l sample l o c a t i o n s were p lo t t ed i n t h e f i e l d on t ransparent Herculene polyes ter d r a f t i n g f i l m , w i t h a non-reproducable

A l l s o i l samples were logged w i t h r e s p e c t t o number, g r i d coord ina tes , desc r ip t ion and depth a t which they were co l l ec ted . The fol lowing parameters were used i n desc r ib ing t h e s o i l samples:

( i ) Organic - g r e a t e r than 75% by volume composed of s u r f i c i a l p l a n t d e b r i s .
