zone that follows a fault. The fault strikes north 65 degrees east and
dips at about 85 degrees to the northwest. Mullion structure and slicken-
side striations show that movement was in a horizontal direction along
the fault plane. In the adit the fault fissure ranges from 1 to 3 inches in
width. It contains a little quartz, but is open in most places. On both
sides of the fault, the wall-rock is impregnated over a width of 1 to 2
feet with tiny veinlets of bornite and chalcopyrite, and the roof of the
passage is much stained with malachite.

A 28-inch channel sample taken in the adit 96 feet from the entrance,
across the fault and mineralized andesite in the roof, assayed: gold, 0-005
ounce to the ton; silver, 0-15 ounce to the ton; copper, 0-62 per cent. A
second channel sample 32 inches in length was taken across the roof 155
feet from the entrance. It assayed: gold, a trace; silver, 0-015 ounce
to the ton; copper, 0-22 per cent. Ten feet from the face of the adit, on
the west wall the fault fissure widens and contains in one place 12 inches
of sparsely mineralized vein quartz. A channel sample taken here across
12 inches of the vein quartz and 5 inches of mineralized andesite, assayed:
gold, 0-015 ounce to the ton; silver, 0-13 ounce to the ton; copper, 0-91
per cent.

The fault may be readily followed on the surface for 700 feet up the
slope of the mountain to an elevation of 400 feet above the adit and it
probably goes still farther. There are four or five mineralized outcrops in
this distance, but the mineralization is not continuous along the fault.

The Emma claim is at the foot of Bornite mountain about half a mile
northeast of the Usk ferry crossing on Skeena river. The I.X.L. claim
adjoins the east boundary of the Emma and extends up the mountain slope
to an elevation of about 1,500 feet. These claims were staked in 1893
by C. W. D. Clifford, and are reported as the earliest stakings in the area.
The Skeena River Gold Mining Company drove an adit for 165 feet on the
Emma vein in 1897. The following year the claims were Crown granted.
A. J. Lowary and associates did further work on the Emma in 1927 and 1928
and drove an adit on the I.X.L. claim. Mr. Patmore of Prince Rupert is
the present owner.

The Emma adit was driven in an easterly direction at an elevation
of 450 feet for 200 feet along a quartz vein in andesitic lavas. The vein
strikes south 75 degrees east and the dip ranges from 25 to 40 degrees north.
For the first 100 feet the vein ranges in width from 1 to 2 feet. East of a
cross-fault of small dislocation 105 feet from the portal for 30 feet the
vein is 6 feet wide; it then narrows gradually to a width of 2 feet. At
200 feet from the portal the vein is cut off by a fault that strikes south
65 degrees east and dips 50 to 60 degrees southwest. Another almost
parallel fault 12 feet farther east, dipping 35 degrees to the southwest, is
marked by 6 inches of gouge. The adit continues for 50 feet beyond the
