Creek to a cabin on the south fork of the creek at elevation 4,000 feet.
The workings are on the southwest side of a spur that separates the south
and east forks of the creek, half a mile southeast of the cabin. The claims
are owned by J. Creagh.

At elevation 5,175 feet a 15-foot adit is driven northeast along an
aplite sill, 3 feet in width, that intrudes interbedded sandstones and
argillites. The sediments and sill strike north and dip 35 degrees east.
The sediments are rust stained at their contacts with the sill, but contain
only small amounts of disseminated pyrite.

A sulphide vein outcrops 200 feet farther east at elevation 5,280 feet.
The vein is 60 feet long and ranges from 3 to 12 inches in width. It
consists largely of solid black sphalerite with some pyrite. The vein
strikes northeast and dips 45 degrees northwest. It lies in bedded grey-
wacke, which strikes north 30 degrees west and dips 15 degrees northeast.
An 8-inch channel sample taken across a particularly rich section of the
vein in a small open-cut assayed: gold, 0-015 ounce a ton; silver, 1-36
ounces a ton; zinc, 41:95 per cent.

Another sphalerite vein of similar appearance occurs 150 feet farther
east and 60 feet farther up the slope. This vein, prospected by one open-
cut, is 35 feet long and ranges from 3 to 12 inches in width. It strikes
north 80 degrees east and dips 50 degrees north. At the open-cut near the
centre of the vein, the rock on the north side is slightly sheared over a
width of 6 feet and is traversed by small seams of pyrite.

In an open-cut 200 feet farther east, at elevation 5,440 feet, there is a
sheared zone 6 feet wide that contains numerous stringers of black
sphalerite, one of which attains a width of 4 inches. The shearing is very
weak and the sulphide stringers pinch out a short distance on either side
of the open-cut. A similar sheared zone containing scattered sphalerite
stringers over a width of 10 feet, occurs 50 feet below and 75 feet farther
along the slope. These sphalerite stringers pinch out 10 feet either side
of an open-cut that exposes the greatest width of mineralization.

Roughly 800 feet farther east along the southeast side of the spur,
a relatively strong vein occurs in voleanic rocks. This vein has been
traced by four open-cuts for 300 feet up the steep slope between elevations
of 5,475 and 5,700 feet. The vein strikes northeast and dips 65 degrees
northwest. It consists largely of black sphalerite with a little galena,
pyrrhotite, and chalcopyrite. In general the vein ranges from 3 to 12
inches in width, but in several places the fissure is tight, with no vein filling.
A 6-inch channel sample taken across the vein in the second open-cut,
at elevation 5,575 feet, assayed: gold, a trace; silver, 6-43 ounces a ton;
lead, 1-84 per cent; zinc, 11-27 per cent.

On the valley floor, at elevation 5,200 feet, below the last-described
workings, a number of small veins have been prospected by open-cuts.
The veins lie along small fissures of varying strike and dip in voleanic
rocks. They are composed largely of sphalerite with considerable
pyrrhotite and some pyrite. Most of them are less than 50 feet in length
and are too narrow to be of economic value.
