Killarney Claim (38)
Reference: Ann. Rept., Minister of Mines, B.C., 1926, p. 128.

The Killarney claim is on the west side of Brian Boru Basin at the
head of the south fork of Brian Boru Creek, 7 miles southeast of Skeena
Crossing. It is reached by a pack-trail 4 miles in length, which branches
from the Rocher Déboulé mine road 5 miles east of Skeena Crossing and
leads south to the camp at elevation 4,000 feet on Brian Boru Creek.

About 500 feet south of the cabin, the bed of Brian Boru Creek is
formed of fragments of altered rock heavily replaced by pyrite with a
little pyrrhotite, sphalerite, and galena. The immediate banks of the
ereek are muskeg covered, but several hundred feet farther west the
mountain rises steeply and there in an open-cut at elevation 4,200 feet
there is a heavily pyritized, sheared zone 10 feet in width. The mineralized
zone appears to strike up the slope, but has not been found there due to
drift cover.

At elevation 4,250 feet, about 200 feet south of the open-cut, an adit,
now caved at the portal, was driven along an aplite dyke that intrudes
tuffaceous rocks. The dyke is largely concealed by the drift, but its width
exceeds 10 feet. The aplite is considerably altered, with a strong develop-
ment of carbonate, and is impregnated with considerable pyrite and a
little galena and sphalerite. The ground is heavily drift covered in the
vicinity, but 50 feet farther up the slope the mineralized dyke is exposed
in an open-cut. A representative sample of the broken, mineralized rock
taken from the dump at this cut assayed: gold, a trace; silver, 1-10 ounces
a ton; lead, 0-71 per cent; zinc, 2-19 per cent.

Evelyn Group (41)

References: Ann. Repts., Minister of Mines, B.C.: 1923, p. 110; 1925, p. 136.

The Evelyn group, owned by Angus McLean of Smithers, is on the
northeast slope of the northern segment of Hudson Bay Mountain, about
3 miles due southwest of Evelyn station. The property is reached from
the station by a good trail about 4 miles long.

A mineralized, sheared zone in ardesite has been traced by a dozen
open-cuts for 1,000 feet in a horizontal direction and 385 feet in a vertical
direction up a 27-degree slope between elevations of 5,150 and 5,535 feet.
The sheared zone strikes south 55 degrees west and dips about 45 degrees
southeast. It is mineralized with variable amounts of arsenopyrite, pyrite,
galena, sphalerite, and tetrahedrite. A boss of granodiorite that lies to
the southeast, approaches within 600 feet of the vein.

The most extensive shearing and vein formation were seen in two large
open-cuts 45 feet apart at elevation 5,250 feet. In the west cut, the
andesite is sheared, altered, and silicified over a width of 7 feet. The
altered rock is replaced by finely disseminated pyrite and arsenopyrite,
and is traversed by fine veinlets of galena and sphalerite. A chipped
sample taken across 7 feet of the altered and mineralized rock assayed:
