Farther up the hill, on the Kaslo claim, a quartz vein 18 inches wide
is exposed in an open-cut 20 feet long with a 15-foot face. An average
sample collected from the dump of this cut (Minister of Mines report,
1914) assayed: gold, 0-02 ounce a ton; silver, 18 ounces a ton; lead, 8 per
cent; zinc 4:6 per cent.

This property is on the south side of the basin at the head of the
south fork of Boulder Creek, 8 miles due west of Seaton railway station.
The claims are 10 miles distant from the main highway by way of the
pack-trail that follows along the south side of Boulder Creek. Brewer
Brothers were the first to discover silver and copper minerals in a sheared
zone on this property and staked the Last Chance and Little Wonder
claims in 1912. A. R. MacDonald and J. S. Hicks, about 1920, restaked
the ground with a group of four claims named the Sultana, Sultan, Mug-
wump, and Delores claims. The sheared zone was prospected by several
open-cuts, and in 1923 Granby Consolidated Mining, Smelting, and Power
Company put down a single diamond drill hole about 80 feet. The
present owner, G. Christiensen of New Hazelton, carried out some surface
work in 1939.

A mineralized sheared zone is exposed on a bench at elevation 5,200
feet in the coarsely crystalline grey granodiorite that forms the core of
Rocher Déboulé Mountain. The mineralized outcrop is 60 feet long and
ranges from 10 to 20 feet in width. It consists of sheared and altered
granodiorite replaced by pyrite, tetrahedrite, galena, and chalcopyrite
with some quartz gangue. Samples collected by J. D. Galloway (Minister
of Mines Report 1922) assayed about 50 ounces of silver a ton with about
5 per cent of copper and a little gold. The zone strikes north 70 degrees
east and much of the slicing within it dips 45 degrees southeast. In the
open-cut at the northeast end of the outcrop the dip of the slicing changes
from 45 degrees southeast on the northwest side of the zone to 80 degrees
northwest on its southeast side. It appears that the major fissuring was
about vertical along the southeast border of the zone and that the slicing
that dips southeast merges with it there. The drill hole put down in 1923
is located 40 feet southeast of the mineralized zone, at a point opposite
the centre of the outcrop. It was not ascertained whether the hole was
bored vertically or inclined, as it is concealed by boulders. The bore-hole
would probably have missed the mineralized zone unless inclined
towards it.

The Brian Boru group is 7 miles southeast of Skeena Crossing at the
head of Brian Boru Creek, north-flowing tributary of Juniper Creek. The
claims are reached by following the Skeena Crossing-Rocher Déboulé mine
road for 5 miles to where a pack-trail, 4 miles long, follows Brian Boru
