feet in width and dips at a low angle to the west. A representative sample
weighing 2 pounds, collected there by taking chips from different parts of
the outcrop, assayed only a trace in gold and silver. Another large out-
cropping of flat-lying vein quartz occurs several hundred feet farther
north at the same elevation. The exposure measures about 50 by 50 feet,
is flat-lying, and has a thickness of 6 to 7 feet.

A trench 40 feet long and 15 feet deep has been cut across a quartz
albite dyke at an elevation of 1,475 feet. The dyke is sparsely mineralized
with pyrite and chalcopyrite, is altered, and is traversed by an intricate
pattern of intersecting cross-fractures stained with limonite. A grab
sample of the altered rock assayed: gold, a trace; silver, 0-76 ounce to
the ton.

Four hundred feet north of the Four Aces cabin, another altered
quartz albite dyke outcrops on the north bank of Emma creek at an
elevation of 1,175 feet. It strikes south 55 degrees east and dips 20
degrees northeast. It is partly exposed by natural agencies for several
hundred feet and cuts andesitic lava. The foot-wall part of the dyke is
severely altered over a width of 2 to 3 feet and the altered part is mineral-
ized with a little chalcopyrite and chalcocite. A 6-foot adit has been
driven on the best mineralized part.

On the Midget claim, which adjoins the east boundary of the L.X.L.
and lies south of the Four Aces, a 3-foot quartz vein in andesite has been
traced for a short distance at an elevation of 1,400 feet. The vein strikes
south 70 degrees east and dips 40 degrees north. A short distance below,
at an elevation of 1,200 feet, a quartz vein is exposed in two trenches on
the upper part of the L.X.L. claim. This vein is from 2 to 3 feet wide,
strikes south 70 degrees east, and dips 40 degrees north. The quartz is
mineralized with a little pyrite and chalcopyrite.

There are a number of small shear zones in andesite, some of them
well mineralized with bornite and chalcopyrite, on the Golconda claim
which lies east and above the Four Aces claim. Considerable trenching
and stripping have been done between elevations of 1,800 and 2,100 feet,
but the copper deposits so far exposed are not of economic importance.

The property is about one mile southwest of the town of Usk at the
eastern base of Kitsalas mountain. The workings are about 600 feet from
the Canadian National railways, and may be reached by a truck road from
Usk. The claims were first staked in 1914 by James Darby and J. D.
Wells. Development work was carried out by the Kitsalas Mountain
Copper Company who built a small amalgamation mill in 1920 and pro-
duced some gold, silver, and copper. The Usk Mining Company, present
owners, did a little work in the autumn of 1929 and the spring of 1930, but
have since been inactive.
