North-western Aerial Prospectors, Limited (Locality 2)

The property of the North-western Aerial Prospectors, Limited, con-
sists of some twenty claims on the west side of American creek near its
head. A deposit on the Moonlight claim is irregular in shape and may
be a partly replaced sedimentary bed. It contains galena, sphalerite, and
chalcopyrite. Other large and small deposits have been found and all
appear to contain chiefly the silver-lead type of mineralization with
appreciable values in gold.

O.K. Fraction Claim (Locality 76)

1910; Geol. Surv., Canada, Memoir 32.

The O.K. Fraction claim is in the valley of Glacier creek 14 miles
above its mouth. An adit 150 feet long has been driven on a quartz
vein up to 6 feet wide in argillite.

Old Chum Group (Locality 64)

Surv., Canada, Memoir 32.

The Old Chum group of claims is east of Bromley glacier, just east
of the L L and H group. There are three parallel, easterly striking

quartzose zones in argillite mineralized with pyrite, chalcopyrite, sphalerite,
and galena. The northern deposit is 6 feet wide, the central is 4 feet
wide, and the southern is a zone of stringers 15 feet wide.

Ore Mountain Mining Company, Limited (Locality 60)

and 1928; Geol. Surv., Canada, Memoir 159.

The holdings of Ore Mountain Mining Company are north of Bitter
creek and 1 to 2 miles east of Bear lake. The rocks are sediments of the
lower part of the Hazelton group. The contact with the overlying vol-
canic rocks is about 200 feet west of the lower showings and a zone of
dykes lies about 500 feet south.

Some development work has been done on a galena-bearing vein in
sheared tuffaceous sediments at an elevation of 4,500 feet. An adit has
been driven along this vein, but shows only several narrow stringers of
vein matter.

Several parallel veins are exposed in open-cuts and short adits at an
elevation of 3,300 feet. They strike north and dip steeply westward. The
exposures are on a flat area on the mountain side, and the strike of the
veins is along the hillside, so that drift or crosscut adits must be fairly
long to attain moderate depths. One of the veins is locally 4 feet wide
and is a replacement vein in a shear zone. Pre-mineral and post-mineral
faults striking north are present and also post-mineral faults, with small
offsets, striking northeast. One of the latter faults is occupied by a nar-
