Silver Bow Group (Locality 82)

References; Annual Report of the Minister of Mines, British Columbia, 1906; Geol.
Surv., Canada, Memoir 32.

The Silver Bow group is on Glacier creek southwest of the Ruth and
Francis group. Argillites and volcanics are interbanded and a fractured
and silicified zone follows a band of volcanic rocks. The zone has been
traced for 700 feet and is mineralized up to a width of 15 feet with pyrite,
galena, tetrahedrite, and probably jamesonite. ;

Silver King Claim (Locality 85)
References: Annual Report of the Minister of Mines, British Columbia, 1906; Geol.
Surv., Canada, Memoir 32.

The Silver King claim is on Glacier creek and is surrounded by the
holdings of L. and L. Consolidated Mines. The vein on the Columbia
group has been traced for 300 feet into the Silver King claim. It is
sparingly mineralized with galena, pyrite, stibnite, sphalerite, and
tetrahedrite.

Silverado Group (Locality 93)

The Silverado group of mineral claims is on the mountain side south-
east of Stewart. The country rocks are breccias and lava flows of the
Hazelton group. The rocks are sheared locally and in some places have

been changed to sericite schists.

At an elevation of about 4,000 feet several quartz veins mineralized
with pyrite and tetrahedrite are exposed in several adits, one of which is at
least 400 feet long. Two or three of these veins, on which much of the
early work was done, strike northwest and dip gently eastward into the
hillside. They are individually less than 2 feet wide, but contain small
shoots of high-grade silver ore. The veins are richer at the surface than
underground. A total of 9 tons of ore was shipped from these veins in 1921
and 1925. The ore averaged 150 ounces of silver a ton and contained 3:5
per cent copper. Two vertical quartz-sulphide veins striking northwest
and each 4 to 6 feet wide occur in the vicinity of the narrow, ore-bearing
veins, but have not been explored underground.

At least four quartz-sulphide veins are exposed at an elevation of
1,800 feet and on these mining work was centred during the period 1924
to 1927. They strike northwest and have been traced on the surface for
lengths of about 400 feet. The two upper veins dip northeast and the two
lower ones southwest. The largest vein is one of the two lower veins. It
is 5 feet wide at its junction with a branch vein and contains quartz,
pyrite, chalcopyrite, galena, sphalerite, tetrahedrite, and native’ silver, and
at the Junction with the branch vein is high-grade silver ore. A cross-
cut adit driven to intersect this vein at a depth of 170 feet, although
long enough to have reached the vein, did not intersect it. The other three
veins are in most places less than 2 feet wide, but contain local bunches
of rich silver ore.
