or more. Sloughing has obscured the attitude of the veins, of which some are parallel
to the formation and others cut across it. The vein-quartz is only sparingly mineral-
ized with pyrite.

Lots 10440c to 10443c and several others were held in 1933 by B.C.
Lot 10443C Cariboo Gold Fields, Limited. Lot 10448c is underlain by hard, mas-
(48). Sive grey quartzite and fine quartz pebble conglomerate striking about
north 10 degrees east and dipping 30 degrees east. Several strands of
the Grub Gulch-Coulter Creek fault run through the north-western half of Lot 10443c.
Near them the rocks are silicified and jointed, strike north 20 degrees east and dip 80
degrees westward. A vein crosses the western boundary of Lot 104438c, 315 feet south
of the north-west corner post. The vein has been stripped for 100 feet along its length,
strikes north 55 degrees east, dips 65 degrees north-west, and ranges from 8 inches to
4 feet in width. A shaft on it was sunk to a depth of 20 feet. Selected pieces of
leached and oxidized quartz from the dump assayed: Gold, 0.04 oz. per ton; silver,
trace.
The Nelson Creek group of six claims is recorded by B. Fink, of
Nelson Creek Barkerville. The claims lie south of Slough Creek and west of Nelson
@).: Creek. On the south the claims adjoin the Canyon group of eight
claims located by W. M. Hong. The claims are crossed by the Last
Chance-Nelson Creek fault which was uncovered in the autumn of 1945 by hydraulick-
ing in a pit several hundred feet west of the western boundary of Lot 10544c. The
fault-zone where exposed in the hydraulic pit is about 100 feet wide. On the western
side a large slab of quartz 2 to 8 feet thick and about 30 feet long lies on the foot-wall
of the fault. The quartz is vuggy and is sparsely mineralized with pyrite, galena, and
sphalerite. A selected sample of the best mineralization assayed: Gold, nil. Whether
this is a piece of drag quartz or whether the quartz was deposited in the fault-zone is
not known. About 200 feet to the north a 4-foot quartz vein continues northward for
some distance and may be the extension of the vein exposed in the hydraulic pit.
The following Table IX lists assays of samples from various parts of the Stanley
area. The veins are not described elsewhere in this report.
