the sheared zone at elevation 6,000 feet, and is followed up and over
the shoulder of the mountain at elevation 6,250 feet, from where it extends
down into the valley of a small stream that lies half a mile north of
Balsam Creek.

The claims blanket a small diorite stock of irregular shape that
intrudes greywacke, argillite, and quartzite. The shear zones occur in
the diorite or along faults bordering large blocks of the sediments that
lie within the stock. In the vicinity of the workings the diorite gives place
to sedimentary rocks below an elevation of 5,400 feet. The No. 1 cross-
cut adit, driven 430 feet north at elevation 5,150 feet, is entirely in the
sediments. They are poorly bedded in the adit, but in general strike east
and dip 10 degrees south.

The sheared zone on which most of the early work was done outcrops
at intervals up a steep ravine (slope of 34 degrees) between elevations of
5,425 and 5,825 feet. It strikes from north 30 to north 45 degrees west
and dips 45 degrees southwest. In the No. 3 adit, at elevation 5,450 feet,
the sheared zone ranges from 1 to 4 feet in width. It consists of soft,
rusty, pulverized rock largely leached of its sulphide content. An 18-inch
channel sample taken across this material, 65 feet from the face of the
adit, assayed: gold, 0-015 ounce a ton; silver, 0-09 ounce a ton; tungsten,
none. In the No. 4 adit at elevation 5,690 feet the sheared zone is also
composed largely of soft, ground-up, rusty, altered rock and has an
average width of 3 feet. For 70 feet from the portal the sheared zone is
in sediments, ‘but from 70 feet to the face of the drift the hanging-wall
is diorite. Along the part of the drift in the sediments the sheared zone
is replaced by considerable vein quartz that carries a little pyrite. A
channel sample taken across the vein 50 feet from the portal, where there
is a 24-inch width of vein quartz containing 3 per cent of pyrite, assayed:
gold, 0-54 ounce a ton; silver, 0-79 ounce a ton; tungsten, none.

No. 2 adit is 100 feet southeast of and 35 feet below the No. 3 adit.
It is driven 50 feet along a vein that lies parallel to the main sheared
zone. This vein ranges from 6 to 24 inches in width, and has been traced
less than 100 feet. The hanging-wall is diorite and the foot-wall is
altered argillite. The vein consists of the following gangue minerals, in
order of abundance, hornblende, quartz, and biotite, and carries a little
pyrrhotite, arsenopyrite, and chalcopyrite.

Two parallel sheared zones 15 feet apart outcrop directly above No.
4 adit between elevations of 5,800 and 6,000 feet. Both range from 1 to
4 feet in width. They consist of sheared, rusty, altered diorite with a
small sulphide content. At elevation 6,000 feet the upper, sheared zone
gives place to a strong quartz vein that increases from 1 to 10 feet in
width within 50 feet up the slope. The quartz vein continues up the slope
to the top of the ridge, then runs along the shoulder of the mountain
at elevation 6,250 feet for about 300 feet before dropping down into the
valley on the north. The vein strikes north 45 degrees west and dips from
40 to 75 degrees southwest. It is well exposed between elevations of
6,000 and 6,100 feet, where it has an average width of 7 feet but is only
sparsely mineralized with pyrite. In a cut at elevation 6,225 feet the
vein is 18 inches wide and the quartz carries possibly 5 per cent of wolfra-
mite and a little chalcopyrite. For 300 feet along the top of the ridge
