NELSON. B. C.

The Pactolus Group is underlain by Hoesland vol-

CRnlCS. The general strike of the formations Is northwester-

ly wlth dips of 40 to 90" southwest. A cross section of the

rocks Is 8XpOSed along Gold Greek. horth of the shingle

mill there 1s a ohlorite hornblende greenstone schist derived

from an andesitic tuff. at the mill a 250 foot width of

fresh felspar porphyry (andeslte, greenstone). Proaeedlng

southwest this is followed by 1500 feet of fresh andesltlc

greenatone, and 1800 feet of alternating andesltic and bas-

nltia rocks, sometimes massive and sometimes SChiSted or

sheared parallel to the general trend of the formations.

In this 1800* width there tire bands of pyrite

mlneralizatlon. The pyrite occurs in three principal types

of rock. The first Is in a light bleached aLtered sahlst;

the second In harder siliclfled brownish and purplish alter-

ed schist; the third In a more massive basaltic rock show-

ing epldote and having a nodular weathered surfaoe. The

mlnerallzod bands parallel the formations.

In 1887 good gold values wars obtained from

the gossan of one of the pyrltized belts. ii small mill

was installed but was unable to treat the sulphldes.

Values were much lOW8r In the unoxidized ore.

To the southwest of the Pactolus there is e.

rock resembling a diorite or diorlte porphyry. In places

this is sohisted similar to the rocks of the Hossland

k3taries. This may be either a member of the series or e

later intrusive.
