and dip from 65 to 75 degrees north. The fissured zones range from 1 to 3
feet in width and contain narrow sulphide lenses consisting largely of
pyrrhotite with small amounts of pyrite, arsenopyrite, and chalcopyrite.
At the surface the sulphide lenses are narrow and short. They do not exceed
6 inches in width and for the most part are less than 3 inches. A 100-foot
shaft is sunk on the more northerly of the two zones. At the collar of the
shaft the sheared zone carries very little sulphide, but during sinking
operations some massive sulphide lenses were encountered containing con-
siderable chalcopyrite. Some of the ore from the shaft is piled in two nearby
heaps of about 20 tons. A representative sample from the smaller of the
two piles assayed: gold, 0-20 ounce a ton; silver, 7-25 ounces a ton; copper,
6-50 per cent; nickel, none. The westerly continuation of this zone is
exposed several hundred feet farther west on the side of the road. It has
been trenched for 50 feet and is prospected by a shaft 30 feet deep. The shaft
is sunk on two fissures from 2 to 3 feet apart. One fissure ranging from
3 to 6 inches in width consists largely of sheared rock sparsely mineralized.
The other fissure carries a 3-inch sulphide vein at the surface, which increases
in width to form a pyrrhotite lens 2 feet in width 10 feet down the shaft
at the water-level. A representative sample taken from a small heap of
pyrrhotite lying at the collar of the shaft assayed: gold, 0-04 ounce a ton;
silver, 0-16 ounce a ton; copper, 0-30 per cent; nickel, none.

At the north end of the low ridge, 1,000 feet northeast of the 100-foot
shaft, a narrow dyke of porphyritic diorite has been followed for about 150
feet. by several open-cuts. In this vicinity the tuffs strike north and dip 40
degrees east. The dyke runs across the nose of the ridge, striking south
70 degrees east and dipping 75 degrees north. The dyke ranges from 8 inches
to 4 feet in width. Short quartz lenses ranging from 0 to 10 inches in width
lie along both walls. In some places the dyke is fractured along planes along
the strike of the dyke and is traversed by small quartz stringers. The
quartz carries a little pyrite and chalcopyrite. A representative sample of
the mineralized quartz taken from the east open-cut assayed: gold, none;
silver, 0-12 ounce a ton; copper, 0-79 per cent.

The Belton and Cap claims, owned by Denis Comeau, are on the north-
west slope of Rocher Déboulé Mountain 4 miles south of New Hazelton.
A good trail leads up to the property from Comeau’s ranch at the foot of
the mountain.

A little development work was done on a mineralized, sheared zone on
this property, each year from 1914 until 1918. During 1917 a 29-ton
shipment of ore was made to Ladysmith smelter, an average sample of
which assayed: gold, 0:03 ounce a ton; silver, 10 ounces a ton; copper,
8 per cent. Some further work was done in 1929.

A brecciated and sheared zone crosses fine-grained tuffs. The sheared
rock is partly replaced by siderite and a little quartz and is impregnated
with considerable pyrite and a little chalcopyrite. It has been traced by
