from the Barkerville road at the foot of Jack of Clubs lake via the Sugar
Creek trail. The claims were explored in 1933, by means of open-cuts,
by the Premier Gold Mining Company, Limited. y

Country rock consists of sheared quartzite and argillite of the Cari-
boo series, striking northwest and dipping 20 to 70 degrees northeast.
The veins range in width from a few inches to 30 feet. Some of the nar-
rower veins are locally well mineralized with pyrite, galena, and pyrrhotite.
Some contain sericite and one or two contain a little chaleopyrite. Low
values in gold are reported, particularly from the veins that are mineral-
ized with sulphides, but no commercial gold ore has yet been found. None
of the veins has been explored to a depth greater than 10 feet.

Some of the veins are parallel to the strike and dip of the country
rock, others are parallel to the strike but dip in the opposite direction,
and many crosscut the rocks at various angles to both strike and dip.
One or two of the crosscutting veins appear to cut veins paralleling the
rocks, but this point could not be established conclusively.

Most of the veins are on the east side of Cooper creek, and no vein
has been traced across the creek. This suggests that a fault strikes north-
east along Cooper creek. Geological work farther northeast along Sugar
creek also suggests such a fault and that the northwestern fault block is
offset to the southwest.

RICHFIELD CARIBOO GOLD MINES, LIMITED

The holdings of the Richfield Cariboo Gold Mines, Limited, consist
of many mineral claims southeast of Mink gulch, a few miles south of
Barkerville.

The following report is based on information collected during a brief
visit to the property in 1934. The owners were not in the district at the
time the property was examined, and as the writer did not sample the
showings he has no knowledge of assay values.

The surface showings seen were on the Eldorado No. 4 fraction and
the Eldorado No. 2 claims on the northern slope of the mountain between
Mink gulch and Williams creek, and consisted of quartz veins in massive
grey quartzite of the Richfield formation. An adit 1,500 feet long has
been driven from Mink gulch south toward the surface showings from
a point 700 feet below and 2,500 feet north of them.

The lowest open-cut at an elevation of 5,850 feet on the Eldorado
No. 4 fraction claim is a large one exposing four quartz veins. One is 8
feet wide, strikes south 70 degrees east, and dips 70 degrees north. An-
other is 2 feet wide and strikes north 75 degrees east, and the other two
are 2 and 4 feet wide and strike south 75 degrees east. About 300 feet
farther southeast on the Eldorado No. 2 claim another open-cut exposes
a 7-foot quartz vein striking south 80 degrees east. Southeast of this
at about 50-foot intervals are eight other quartz veins whose widths range
from 3 to 10 feet and whose strikes vary from north 85 degrees east to
seu 60 degrees east. The veins consist of quartz with very little sul-
phide.

The adit has been driven south through gently dipping argillite. Sev-
eral bed veins 2 to 3 feet wide were cut in the first 900 feet of the adit.
