the vein is entirely in the diorite and is covered by talus in most places.
The vein outcrops for about 100 feet as it starts down into the valley on
the northwest slope of the mountain. There it ranges from 5 to 12 feet
in width and carries from 1 to 10 per cent of wolframite with a little
chalcopyrite. A representative sample collected from a small cut where
the vein is 12 feet wide assayed: gold, a trace; silver, 0-05 ounce a ton;
tungsten, 7-03 per cent.

The wolframite is present as small, jet-black crystals, some of which
are as much as 1 inch in length. The vein quartz is coarsely crystalline,
with some well-formed quartz crystals up to 2 inches in length, and there
are occasional yugs and small open spaces. Both quartz and wolframite
are accompanied by a little sericite.

During the 1939 season, Consolidated Mining and Smelting Company
held an option on this property and stripping and sampling operations
were commenced under the direction of A. W. Davis.

The Brunswick group, consisting of the Kaslo and Brunswick claims,
is on Rocher Déboulé Mountain 8 miles south of New Hazelton. The
claims are on the north side of the valley at the head of Balsam Creek,
immediately below the Red Rose property. <A good pack-trail along the
north side of Balsam Creek connects the claims with the Rocher Déboulé
mine road. The late owner, Joe Miller of South Hazelton, carried out
development work on these claims each year beginning in 1912,

The claims are underlain by poorly bedded sedimentary rocks intruded
by small dykes and stocks of diorite and granodiorite. The sediments are
largely argillites and greywacke. Along the creek on the Brunswick claim
the sediments strike northeast and dip 45 degrees southeast.

A quartz vein occurs in a fault fissure on the east bank of the stream
on the Brunswick claim. It is prospected by two adits, the lower at eleva-
tion 4,450 feet and the upper at elevation 4,540 feet, 200 feet farther up
the 29-degree slope. The lower adit is 155 feet long and the upper one,
now caved at the portal, is said to be 90 feet long. In the lower adit the
vein ranges from 1 to 3 feet in width and contains from 1 to 4 per cent
sphalerite, galena, and tetrahedrite. The vein strikes north 60 degrees
east and dips 55 degrees northwest. A representative sample of the
mineralized vein quartz collected from a large heap on the dump assayed:
gold, 0-005 ounce a ton; silver, 7-72 ounces a ton; lead, 0-76 per cent;
zinc, 0-78 per cent. At the portal of the upper adit is a pile of vein
quartz, measuring 20 feet by 15 feet by 3 feet, containing an average of
10 per cent of sphalerite, galena, tetrahedrite, and chalcopyrite. There are
also thirty bags of selected ore that consists of about 75 per cent of these
sulphides. A representative sample collected from a number of bags of the
sacked ore assayed: gold, 0-03 ounce a ton ; Silver, 110-89 ounces a ton;
copper, 1-91 per cent; lead, 17-27 per cent; zinc, 28-40 per cent.
