If the foregoing conclusions are correct the scarch for
further deposits should be directed to mprospected arcas near
the sediments. Judging by the number of deposits in Glacier
gulch and Simpson creek it is to be expected that hundreds of
others lie under the sedimentary shceil that covers the slope
of the mountain between these points. Likewise, but to a lesser
extent because of a steeper contact dip, they may be expected
between Glacier gulch and Toboggan creek. The strike of the
deposits betwoen Simpson creek and Glacier gulch is very likely
to be in the main toward the peak. The dip may swing from south-
west near the former locality to southeast near the latter. North
of Glacier gluch the attitude is not easily determincd because
cross-folds occur on Toboggan creek and probably have influenced
the fracturing.

Where the sedimentary series is relatively thin it
might be possible to discover underlying deposits by means of
electrical prospecting. It is improbable that deposits undcriying
the sediments are much superior to those near the edge already
discovered, but somewhat large deposits comparable with those on
the southwestern slope may occur, especially if ther~ is well- iq
defined vertical fracturing.

Deposits, probably fairly abundant, occur in other very
irregular fractures where differential movement hastaken place
between rocks of different types, as between the Skeene sediments
and massive volcanic rocks (silver-lead- zine deposit on the north
side of Glacier gulch). Mineral deposits occur along the bedding

and in shear zones on anticlines in the Glacier Gulch tetradymit:

gold deposit, Homestake, and others, in shear zones in granodiorite

(Silver creek) and as replacements in limestone (Silver creek).

It may occur along sedimentary beds or unconformitices (io Grande).
In the Duthic mine one vein occupies 4 favlt and visewhere deposits

may be in fractures of quite different types than those noted. i
