in the first half of 1935, Production has beon made of hand-sortod
gold ore assaying 0.5 to 1 ounce a ton (3 ounces in one case) and
of silver ore assaying 100 to 200 ounces a ton and such rosults aro
to be expected on some properties. Milling grade is not likely to
be over 0.5 ounce for gold and for silver 50 ounces. Vein lengths
up to 3,700 feet are kmovm, but workable lengths hav= been
demonstrated for only as much as 1,100 feet. Widths of 4 to 6 feet
for 600 to 700 feet in the case of gold deposits are mown. Widths
in silver deposits are generally about 1 foot. Workable veins are
known to extend for 600 feet below the surface.

Around the outer part of the main mountain there are
three areas of Lower Cretaceous or Skeena sediments, two of which
occur in part as thin shells on the mountain slope. Simiiar
sediments are probably extensive below the drift in the iarge
valleys surrounding the mountain. It is believed that the series
once completely covered the main part of the mountain south of
Toboggan creek. Erosion has removed most of it and has cut into
the core, which as now exposed is made up mainly of massive
volcanic rocks. In the centre of these there is believed to be
an inner granitic core, which may occur below the ice in Glacier
gulch and which may also be represented at the surfece by small
stocks on the northern peak and at other places by dykes. In
the gravels of Glacier gulch there is such an unusual abundance
of granitic boulders that the presence of granitic rock below
the glacier is strongly suggested. North of Toboggan creek
volcanic rocks occur above the Skeena sediments.

Tt is believed that the granitic rock in the centre was
sntruded under great force and caused doming of the rocks, as
well as many minor deformations. much fracturing, induration,
and alteration. The sedimentary beds of the Skeena formation

originally were in flat layers and, therefore,adjustec themselves
