Properties on the North Side of Rocher Déboulé Mountain.

On the north side of Rocher Déboulé mountain the granodiorite forms
the whole face of the mountain and there are several mineral locations
on which very little work has been done, and which show very little promise.
The Daley West property has been opened to the greatest extent, so a brief
description will be given.

THE DALEY WEST PROPERTY. General Description. The Daley West
property is situated about 2 miles southeast of New Hazelton and is
reached by a good wagon road. It is about 3,500 feet from the northern
contact and 6,500 feet from the eastern contact of the granodiorite with the
sediments, and consists of a mineralized shear zone in the granodiorite.

The shear zone strikes north 15 degrees east and dips 65 degrees
northwest; it is from a few inches to 3 feet in width and is traversed by a
vein of quartz which carries the sulphides. The vein is exposed for about
500 feet up the hillside from the lower tunnel which is at about 1,675 feet
altitude, and a second tunnel is driven 125 feet above the lower one.

The lower tunnel is 155 feet long and follows two small stringers which
are 2 to 3 feet apart and separated by partly decomposed granodiorite;
farther in the tunnel the stringers join and then separate as before. Each
of the stringers carries an inch or two of chalcopyrite.

The upper tunnel is driven on the vein for 300 feet and carries a little
chalcopyrite for about 100 feet in a vein up to a foot in width; the vein is
then practically barren until near the face when a little chalcopyrite is
again encountered, this time accompanied by some pyrrhotite which is not
in evidence either on the surface or in the rest of the tunnel. The principal
mineralization in the vein is of arsenopyrite carrying a very small amount
of gold. The surface showings are not any more promising than those in
the tunnel, and in view of the very low assays in gold the property does
not appear to warrant any further expenditure.

In Bulletin No. 2, 1907, of the British Columbia Bureau of Mines,
the following assays are given.

An average sample of about a ton of ore taken from the tunnel,
mainly arsenical iron, gave: gold, Ol ounce; silver, 1-5 ounces; copper,
0-9 per cent.

A sample of solid arsenical iron gave: gold, 0-1 ounce; silver, 1-7
ounces; cobalt, nil; nickel, nil.

Properties on the East Side of Rocher Déboulé Mountain.

BLACK PRINCE GROUP. General Statement. This group is situated at
the head of Mud creek near the eastern border of the main granodiorite
mass, and is reached by a good trail from the New Hazelton-Telkwa
wagon road. The trail is about 6 miles in length and leaves the road just
north of the Grand Trunk Pacific Railway crossing. There are two main
occurrences on the property, which are exposed on the face of a steep hill
and are opened by cuts and short tunnels.

Description of Deposits. The first occurrence is apparently a shear
zone in the granodiorite, with a maximum width of about 8 feet, definite
walls, and containing one to four parallel stringers of quartz. The material
in the zone is crushed and altered granodiorite which is considerably
mineralized. The zone strikes north 62 degrees west (magnetic), dips
