REPORT OF THE MINISTER OF MINES, 1929.

This company was incorporated in 1925 to develop a grouping of claims

Black Hill situated at the head of the South fork of Glacier creek. During 1929 an

Mining Co. option was obtained on two-thirds of the stock of the Black Hill Mining

Company by the Northern Metals Holding Syndicate, a development syndicate
of 12,500 units of $10 par value, organized by the North Coast Finance Company, Limited, of
Stewart.

The ore-deposit consists of a series of east-west striking, steeply dipping quartz yeins 6 to
8 inches wide, sparsely mineralized with galena, zinc-blende, grey copper, and occasionally
some chalcopyrite. Another series of well-defined north-south striking, steeply dipping, quartz-
calcite-barite veins 8 to 12 inches in width, well mineralized with zinc-blende, grey copper, galena,
and jamesonite, carrying high silver values, also occurs on the property. These latter show
indications of sustained ore-shoots for lengths of about 40 feet, with intervening spaces in the
veins of 20 to 80 feet of low-grade material. The property offers promise for development of
small tonnages of high-grade shipping-ore, with interesting indications of possible augmentation
at the junctions of the two series of veins. The formation is a complex of intrusive andesite
into argillite. The veins seem to favour the contact area of the two rocks and in places seem
to follow the course of a dense rhyolitie dyke. In traversing the argillite the veins appear to
“stringer out ” and condense again on merging into the voleanics.

The showings are between altitudes 3,850 and 4,650 feet. Active and efficiently guided
exploration was inaugurated early in the summer and continued into the winter months.
A summer camp was established at altitude 4,200 feet and later a good winter log camp was
erected on the sheltered slope of the mountain.

No. 2 tunnel on No. 3 vein was advanced 68 feet and, later, work was concentrated on
driving No. 1 tunnel on No. 4 vein, 90 feet lower down the slope of the hill. These two veins
should junction at approximately 312 feet from the portal of No. 1 tunnel, with backs at that
point to about 125 feet. At the time of the first examination (June 20th) No. 2 drift-tunnel had
been advanced 45 feet, showing the vein to be about 8 inches wide and well mineralized.
A sample across the vein on the north wall of the face assayed: Gold, trace; silver, 52.6 oz.
to the ton; copper, trace; lead, 0.2 per cent.; zine, 6.2 per cent. A sample of a streak of
massive sulphides 2 inches wide, about 20 feet from the tunnel portal, assayed: Gold, 0.04 oz.
to the ton; silver, 82.3 oz. to the ton; lead, 6.4 per cent.; zine, 6.3 per cent. A sample across
an average 8-inch width of a vein exposed in a trench 30 feet long at altitude 4,600 feet assayed:
Gold, 0.04 oz. to the ton; silver, 86.2 oz. to the ton; lead, 9.8 per cent.; zine, 6.8 per cent.
The outcrop of this vein is highly manganiferous. A sample across an 18-inch width of vein
exposed in a very manganiferous outcrop at altitude 4,650 feet assayed: Gold, 0.01 oz. to the
ton; silver, 5.1 0z. to the ton; lead, 0.3 per cent.; zine, 2.1 per cent.

The property was again examined in October, when work was being pushed in No. 1 tunnel
at altitude 4,475 feet. At that time this tunnel was advanced 78 feet on No. 4 vein with the
objective of the junction-point of this vein with No. 3 at altitude 4,600 feet. An ore-shoot 41 feet
long, averaging 12 inches in width, and heavily mineralized with zinc-blende, jamesonite, galena,
and grey copper, in a calcite-barite gangue, was exposed on the west wall of the tunnel to within
9 feet of the face. In the face the vein had become shattered and sheared with only sparse
mineralization. A sample across 1.3 feet of vein, 69 feet from the tunnel portal and 9 feet from
the face, assayed: Gold, 0.10 oz. to the ton; silver, 112 oz. to the ton; lead, 11.5 per cent.;
zinc, 4 per cent. A sample across 12 inches of vein, 54.6 feet from the tunnel portal, assayed:
Gold, 0.02 oz. to the ton; silver, 47 0z. to the ton; lead, 8 per cent.; zine, 8 per cent. A sample
across 0.95 feet of vein, 37.7 feet from the tunnel portal, assayed: Gold, 0.06 oz. to the ton;
Silver, 31 oz. to the ton; lead, trace; zine, 8 per cent. A sample across 0.95 feet of yein
exposed in a cut on this vein at altitude 4,550 feet and about 160 feet horizontally beyond the
tunnel portal assayed: Gold, 0.04 0z. to the ton; silver, 61 oz. to the ton; lead, 8 per cent.;
zine, 10 per cent.

From this work two shipments of selected ore totalling about 20 tons have been made to the
smelter. It is reported that the shattered condition of the vein (showing in the face) continued
for about 22 feet, when a second ore-shoot came in which is now being drifted on.

This is one of the oldest holdings in the Portland Canal Mining Division, the

Ben Bolt Mining claims being Crown-granted in 1912. The group is situated near the head of
Co. the South fork of Glacier creek, adjoining the Black Hill, and about 4 miles

from the Bear River road. The occurrence is a wide brecciated quartz vein in
