BEAR-MARMOT RIVER DISTRICT

A and T Group (Locality 55)

References: Annual Report of the Minister of Mines, British Columbia, 1928, 1929,
and 19380.

The A and T group of eighteen mineral claims is on the west side of
Bear river south of Independence creek and lies on the southern edge of the
belt of dykes crossing Bear and Salmon Rivers districts. The property was
bonded in 1929 by the Consolidated Mining and Smelting Company who
after doing 1,500 feet of diamond drilling relinquished the option.

At an elevation of 2,400 feet a rusty shear zone 100 feet wide, in vol-
canic rocks, is sparsely mineralized with pyrite and chalcopyrite. At 2,500
feet above sea-level another shear zone, interrupted by wide, granitic dykes,
contains 8 feet of chalcopyrite ore assaying about 4 per cent copper. The
length of this body is not known but is perhaps 100 feet or less. An ill-
defined shear zone about 3,000 feet above sea-level is sparsely mineralized
with iron sulphides and chalcopyrite for a width of 70 feet.

Aberdeen Group (Locality 96)

References: Annual Report of the Minister of Mines, British Columbia, 1923; Geol.

Surv., Canada, Memoir 159.

The Aberdeen group of mineral claims adjoins and lies west of the
Porter Idaho. The group is underlain by volcanic fragmental rocks and
lava flows. They strike northeast and dip northwestward at moderate
angles. Locally the rocks have been severely sheared and as a result bands
of fissile schist strike northwest. One of these bands of schist, 100 feet
wide, is stained yellow with iron rust. Open-cuts have been made and a
short adit has been driven in the shear zone, but no primary sulphide is
visible.

Ajax Claim (Locality 88)

Reference: Geol. Surv., Canada, Memoir 32.

The Ajax mineral claim is on the south fork of Glacier creek at the
contact between a body of augite porphyrite and sediments to the west.
A zone of fissuring, striking east and dipping north, contains small lenses
of zine blende with some pyrite and galena.

Albany Mining Company, Limited (Locality 88)

References: Annual Report of the Minister of Mines, British Columbia, 1925, 1926,
and 1927; Geol. Surv., Canada, Memoir 159.

The holdings of the Albany Mining Company, Limited, are on the
south fork of Glacier creek, The camp and most of the workings are about
1,700 feet above sea-level. The country rock is argillite near the con-
tact of a large body of augite porphyrite.

The first development work done on this property consisted of open-
cuts and a short adit on a 2-foot quartz-sulphide vein. Bunches of sulphide
locally distributed in the vein assay 0-2 ounce of gold, 10 ounces silver a
ton, and 10 to 20 per cent lead, but are not of commercial importance.
