The Atlas Gold Copper Mining Company, Limited, holdings are west
of the George Copper group on Upper Bear river. The company diamond-
drilled a copper-bearing deposit and by means of diamond drilling also
searched for the western extension of one of the George Copper showings,
but with discouraging results.

Aztec Group (Locality 58)
References: Annual Report of the Minister of Mines, British Columbia, 1920 and 1922.

The Aztec group of four mineral claims is west of Bear river opposite
Bitter creek.

Two veins in voleanic rocks are exposed at several places on the hill-
side at elevations of 2,300 feet and higher. The “ Iron vein” is up to 9 feet
wide and consists of quartz containing pyrite and chalcopyrite. The
“Copper vein” apparently strikes westward up Bear River ridge. It is
a quartz vein mineralized with chalcopyrite and iron sulphides. Open-cuts
between elevations of 2,600 and 3,800 feet exposed vein matter up to 6
feet wide believed by the owners to be on the “Copper vein.” It locally
contains a foot or more of very high-grade chalcopyrite ore.

Barite Gold Mines, Limited (Locality 23)
Helerene bee Annual Report of the Minister of Mines, British Columbia, 1924 and
925.

The holdings of the Barite Gold Mines, Limited, are on the north side
of Bear river near its head and at an elevation of 5,000 feet. Gash veins
of barite are numerous in a zone 380 feet wide and several hundred feet
long. Barite veins a foot wide occur elsewhere on the property. Another
vein a foot wide is sparsely mineralized with galena.

The holdings of the Bayview Mining Company, Limited, consist of
the Bayview group of mineral claims and are on the eastern slope of mount
Dolly 24 miles north of Stewart. Most of the discoveries are near the
edge of the Coast Range batholith, some within the batholith, some in
adjacent argillite, and some in adjacent volcanic rocks.

Three veins have been explored on the Bayview group. The work-
ings are about 4,000 feet above sea-level. The veins are parallel to each
other and to the contact of the Coast Range batholith which here strikes
west. One vein is at the edge of the batholith and the other two are within
700 feet of the edge. The veins are 2 feet or less in width and consist of
pyrite, galena, sphalerite, and tetrahedrite in a gangue of quartz, The
development consists chiefly of open-cuts from some of which ore has been
shipped. A total of 9 tons of ore shipped in 1925 assayed 170 ounces of
silver a ton, 16 per cent lead, 21 per cent zinc, and a little more than a
dollar in gold a ton.
