The country rock consists of andesitic flows, chlorite schists, and green
tuffaceous rocks, intruded by a number of small lamprophyre dykes. The
exploratory work has been done on a system of quartz veins that strike
northeast and dip from 15 to 35 degrees northwest. The veins are rela-
tively short quartz lenses repeated along the strike. A quartz vein inter-
sected by the main adit follows a fault that strikes north 30 degrees east
and dips 75 to 85 degrees northwest. Other veins with angles of dip rang-
ing from 15 to 20 degrees join the fault from the southeast side.

The main crosscut adit is driven north 56 degrees west for 450 feet.
The first 100 feet or more is heavily timbered as it passes through loose
material, but elsewhere the walls are of relatively strong andesite flows.
Four hundred feet from the portal a curving drift runs east of north for 63
feet and west of south for 120 feet. At this point in the crosscut a quartz
vein or lens ranging from 2 to 11 feet in thickness runs for 30 feet in
either direction. Its strike is north 10 degrees east and the dip is about
vertical. The quartz is sparsely mineralized with bornite and chalcopyrite
and a little free gold. Twenty-five feet north of the main crosscut a raise
follows the lens for 30 feet. The quartz lens pinches out abruptly a few
feet north of the raise. Beyond it, a smaller lens appears towards the face
of the drift. Thirty feet south of the main crosscut the large lens again
pinches out, but is joined by a 2-foot quartz vein that dips west towards
it at 20 degrees. The large quartz lens lies along or close to two parallel
faults spaced from 3 to 6 feet apart. Both faults dip from 75 to 85 degrees
west and they are well exposed in the south drift which follows them most
of the way. Twenty feet from the face of the south drift a 14-foot crosscut
to the east intersects a 10-inch quartz vein dipping 15 degrees west. This
comparatively flat-lying vein assumes a steeply dipping attitude on meet-
ing the fault and follows it down the dip a short distance.

The No. 2 adit is 275 feet northwest of the main adit and about 80
feet higher at an elevation of 500 feet. It runs north 70 degrees west for
415 feet. At 132 feet from the portal a drift runs south along a fault for
26 feet. At the face of the drift a winze 30 feet deep shows from 2 to 3
feet of vein quartz along its west side. This is an upper part of the large
lens on the main level. It is short along its strike. Three hundred and
seventy feet from the portal entrance the crosscut adit intersects a quartz
vein that strikes north 30 degrees east and dips from 30 to 35 degrees
northwest. This vein ranges from 1 to 2 feet in width and consists of
white, barren-looking quartz. A drift running northeast along the vein
from the crosscut is 75 feet long and in it the vein continues for 60 feet
before pinching out. A crosscut driven west 53 feet from near the end of
the north drift failed to disclose other veins. A drift to the southwest
along the vein is 90 feet long and the vein pinches within a few feet of
the face. A 19-inch channel sample taken across the vein 15 feet south
of the main crosscut assayed only a trace of gold and silver.

At an elevation of 605 feet and approximately 150 feet northwest of
the No. 2 adit, a 67-foot shaft has been sunk on a quartz vein that ranges
from 2 to 5 feet in width and dips 30 degrees northwest. The vein is
streaked with fine bands of bornite and chlorite schist. A 36-inch channel
sample taken across the vein 29 feet from the shaft head on the southwest
