The rocks on the claim consist principally of slates and argillite. The
slates have well-developed secondary cleavage, and the bedding is poorly
marked. On the knife-edge peak 600 feet above the camp the slaty cleay-
age strikes north 30 degrees east and dips 65 degrees northwest, but no
bedding is discernible. At the base of the peak near the cabin the slaty
cleavage has a similar strike and dips 55 degrees northwest, and the bed-
ding strikes north 40 degrees east and dips 25 degrees northwest. A small
quartz diorite stock intrudes the slates and forms part of the peak of the
mountain at an elevation of 5,600 feet. A coarsely crystalline hornblende
gabbro dyke was encountered in the prospect workings.

At an elevation of 5,400 feet an adit was driven for 206 feet in a
direction south 38 degrees east in an effort to locate the quartz vein that
furnished the float. The work was done on the supposition that the vein
lay parallel with the bedding and that the bedding dipped steeply to the
northwest. The adit intersects 80 feet of argillite, then a 40-foot horn-
blende gabbro dyke, followed by 86 feet of argillite and slate. There is
a 10-inch gouge-filled shear zone 6 feet from the face. It strikes north
30 degrees east and dips 55 degrees northwest. A second adit was driven
for 140 feet at a point 200 feet below the upper adit and again no vein
was struck. At the time the property was visited, early in August 1935,
the lower adit was completely buried by a large snow drift.

Keystone and Lucy O’Neil Claims
Reference: Annual Report of the Minister of Mines, B.C., 1921, p. 44.

The Keystone and Lucy O’Neil claims are on the north fork of
Maroon creek, about 8 miles east of Kitsumgallum lake. The Keystone is
on the west side, and the Lucy O’Neil on the east side, of the creek, a short
distance north of the forks. A pack-horse trail now much overgrown follows
Maroon creek from the lake to the claims.

A 3-foot quartz vein heavily mineralized with pyrite and chalcopyrite
outcrops in a cliff of massive, grey diorite on the east side of the stream just
above the water. The vein is on the lower side of a dark, fine-grained
diabase dyke about 3 feet wide that strikes north 30 degrees west and dips
60 degrees northeast. Some vein quartz also occurs on the hanging-wall side
of the dyke, but only in small, discontinuous lenses. The diorite adjoining
the veins is altered and pyritized for several inches.

A shaft, 20 feet deep, was sunk on the vein in 1921 by George Little
and associates. At the bottom of the shaft the vein is 44 feet wide and the
quartz is evenly mineralized with pyrite and chalcopyrite. Two channel
samples were taken across the vein, close to the bottom on the east side of
the shaft. The first sample, 32 inches in length, taken adjacent to the
dyke, assayed: gold, a trace; silver, 0-89 ounce a ton, and copper, 3-48 per
cent. The second sample, from the remaining 22 inches of the vein adjoin-
ing the diorite, assayed: gold, 0-02 ounce a ton; silver, 0-68 ounce a ton: and
copper, 1-51 per cent; across the 44 feet the copper averages 2-68 per cent.

On the projected extension of the vein on the west side of the stream, 60
feet distant, a shear zone has a similar strike and dip, but has no vein filling.
The diabase dyke lies 15 feet north of the shear zone, but has a more
