NORTH-WESTERN DISTRICT (No. 1).

argillite carrying zinc-blende, galena, pyrite, in what is known as the “ Portland Canal fissure-
zone.” The yein is heavily graphitic. Extensive underground exploration from tunnels at
different levels was at one time carried out by the Pacific Coast Exploration Company. Three
of the claims have reverted to the Ben Bolt Mining Company, 43 Victoria Street, Toronto, and
the Chicago Fraction to Samuel Morrison, 1150 Main Street, Vancouver. The work has resulted
in only partial exploration of the ore-shoots. The prospect has been idle for a number of years,
but warrants further exploration for the possible development of mill-grade ore.

This company was incorporated in March, 1928, with the registered office in

Mayou Gold Stewart. The property is situated on the north side of Bitter creek, above

Copper Co., Ltd.* and on either side of the Radio-Stewart Company’s property. The trail is a

continuation of the trail to the latter property. The group consists of the

following thirty claims: Alberta, Alberta No. 1 to No. 7, Ophir, Ophir No. 1 to No. 3, Morgan,

Morgan No. 1 to No. 6, Mayou Fraction, Mayou, Mayou No. 1 to No. 4, Dot, Dash, Russ, Sandy,
and Mayou Fractional. These are all owned by the company and are being surveyed.

The main showings consist of a series of narrow shear-zones mineralized with galena and
associated with dykes in argillite country-rock. Work has been concentrated during the summer
on driving three tunnels. No. 1 tunnel, at elevation 5,380 feet, has been driven for 120 feet on
a small stringer of galena ore. This yein strikes N. 18° W. and varies from 2 to 18 inches in
width. Near the end of the drift the vein has been cut off by a dyke.

No. 2 tunnel, at an elevation of 5,280 feet, has been driven about 130 feet on a small stringer
striking N. 10° W. At this point a large dyke comes in at an acute angle from the west ang
apparently cuts the stringer off. The drift was continued for a further 70 feet to the far side
of the dyke and another small stringer was encountered on its western contact with the
argillites. It is probable that the original stringer follows the eastern wall of the dyke. No. 3
tunnel, at an elevation of 4,600 feet, was put in on a small showing of galena on a contact
between the east wall of a dyke and the argillites.

The veins are small, but appear to be well mineralized. The mineralization consists chiefly
of galena with some zinc-blende and pyrite. There are also several open-cuts in the hillside
with showings up to 20 inches wide, containing a little galena. On the top of the mountain
there is a copper-showing consisting of a dyke striking N. 35° W. and dipping south-west. This
contains stringers of chalcopyrite up to 3 inches wide. It has been exposed by two open-cuts,
but not enough work has been done to enable an opinion to be formed as to its value.

Work has been done from a tent camp above timber-line on the south side of the mountain.
The claims are reached by a fairly good trail which leaves the main road near the north end
of Bear lake, switchbacks up the hill, and then crosses the divide.

Radio-Stewart Mines, Ltd—This property is situated on the north side of Bitter creek,
adjoining the Mayou. Somewhat wider shear-zones than thosé occurring on the Mayou, but with
similar mineralization, are exposed on this property and were further prospected during the
season.

The holdings of this company of the L.L. & H. group are being operated by the

Bitter Creek | Northern Metals Holding Syndicate. The claims are situated at an elevation

Mines, Ltd. of 3,400 to 4,000 feet in Harkley gulch, near the head of Bitter creek, about

7 miles east of the Bear River wagon-road. Camp was established and

exploration proceeded during the summer months. The formation is a volcanic complex of

augite porphyrite intrusive into argillite. Later pyritized syenite dykes cut the formation.

Development has been carried out on a fault-vein, 2.5 feet wide, carrying nodules of high-grade
galena-grey copper ore in heavy gouge.

Two tunnels at elevations of 3.425 and 3,500 feet have opened up a replacement shear-zone
in voleanics, with promising mineralization of galena and zinc-blende, some pyrite and arseno-
pyrite, over good widths. A sample across 3.7 feet in the face of the 35-foot upper tunnel on
this zone at elevation 3,500 feet assayed: Gold, 0.12 oz. to the ton; silver, 7.5 oz. to the ton;
copper, 0.2 per cent.; lead, 4.7 per cent.; zine, 9.8 per cent.

In the lower tunnel, at altitude 3,425 feet, there is a 62-foot width of mineralization with
90 feet similar to the face of the upper tunnel. This is a promising showing and should be
seriously explored with the idea of developing mill-grade ore.
