was crossed. From there a drift on the vein was driven for about 80 feet to the north-
east at a depth of less than 15 feet beneath the surface. The drift is now caved and
the vein can be seen only at two points along this length.

The rocks in and around the workings are interbedded quartz mica schists, dark-
grey argillaceous schist and quartzite striking about north 10 degrees west and dipping
30 degrees to the east. The vein strikes about north 50 degrees east and appears to
dip about 55 degrees to the north-west. The quartz vein reaches a maximum width of
18 inches, is mineralized with ankerite, chiefly along the walls, and, judging from vein
material from the dump, also contains pyrite and galena. The assays of three samples
of selected well-mineralized quartz from the dump are listed in Table VII (Sample Nos.
151F, 152F, and 158F).

The Cohen Incline workings ere about 200 feet north of the north-west corner of
Lot 10729c, about 1,500 feet to the north-east: of the Perkins veins, and between eleva-
tions of 5,250 and 5,300 feet (see Fig. 3). Most of the surface and underground work
was done before Amos Bowman’s examination in 1885. The underground workings are
caved. In 1946 about 1,500 feet of bulldozer stripping was done around the old
showings.

The work has disclosed the presence of and partly explored a group of quartz veins,
some striking north-north-east and the others striking east-north-east.

The rocks in and around the workings comprise a variety of micaceous quartzites,
part of a panel that has a fairly uniform strike of about north 10 degrees east and a
dip of about 20 degrees east.

The Cohen Incline was driven as an open rock-cut north 60 degrees east for 75 feet,
at which point it is about 20 feet below the surface. There a vertical shaft was sunk,
said by C. Fuller to be 70 to 90 feet deep, but now caved and filled with water. Beyond
the shaft a drift continues in the same direction as the incline for 20 feet or more.
This drift, though open, was not examined. The working follows a fracture striking
north 65 degrees east and dipping 75 degrees south-east. The fracture is occupied by
vein-quartz, which in one place is 12 inches wide. Very little quartz is to be seen
in-place.

Fifty feet north of the Cohen Incline shaft is an old caved shaft of unknown depth.
E}xtending northward from the shaft is a trench about 50 feet long that is interpreted
as running along a vein having a strike of about north 25 degrees east and dipping
65 degrees west. To the west of the shaft is a dump containing several tons of vein-
quartz mineralized with pyrite and galena. Sample Nos. 134¥F, 135F, 136F, and 137F
listed in Table VII were taken from selected material from this dump.

North of the above trench is another old caved, cribbed shaft from which a
sloughed surface trench leads 70 feet northward. The trench, which has quartz frag-
ments in the dump beside it, presumably follows a second quartz vein which at the
northern end of the cut is 6 inches wide, strikes about north 10 degrees east, and dips
steeply to the west. Open-cuts to the north indicate that the vein does not extend
farther in that direction.

Four veins are exposed in bulldozed trenches south and west of the north-west
corner of Lot 10729c. An 8-inch unmineralized quartz vein striking about north 60
degrees east is exposed about 150 feet in a direction north 65 degrees west from the
corner post. A second 8-inch vein is 60 feet along a bearing south 30 degrees west from
the corner post. Another vein 6 to 10 inches wide and exposed for a length of 70 feet
lies 100 feet south-west of the corner post.

Two veins lie 280 feet along a bearing south 75 degrees west from the corner post.
The veins were covered by 4 to 5 feet of overburden and were disclosed by bulldozer
trenching. The veins appear to strike 25 to 35 degrees east of north. One is well
mineralized with galena and some pyrite. A long string of fine gold colours was
obtained by panning oxidized vein material from it. This was the first new discovery
of a gold-bearing vein made on Burns Mountain for many years.
