In the Slough Creek section the value of the officially recorded gold production since
1874 is $1,282,176. The total production since 1861 may have been as much as
$3,000,000 or more.

16. The bulk of the placer gold produced from Lightning Creek was mined along
an 8,000-foot stretch extending down-stream from the mouth of Van Winkle Creek
almost to Stanley.

17. The bulk of the placer gold produced from the Slough Creek section was mined
from Nelson and Burns Creeks and from benches on the south side of Slough Creek
between those two creeks.

18. The true fineness of Lightning Creek placer gold is variable but appears to
increase progressively down-stream from Houseman Creek. The fineness is 886 at
Houseman Creek, 905 at Butcher Bench, and 915 at Donovan Creek.

19. The true fineness of placer gold from the Slough Creek section varies slightly
but averages about 930 fine. It is higher than that of placer gold from the Lightning
Creek section.

20. By far the largest amount of placer gold from the Stanley area was produced
from those stretches of Lightning and Slough Creeks and from their tributaries lying
within or very close to the area bounded on the west by the Last Chance-Nelson Creek
fault and on the east by the Butcher Bench-Burns Creek fault.

21. The stretch of rich placer on Lightning Creek coincides with an area of
intensely folded rocks along a major anticlinal axis which runs down the creek.

22. There is no areal correlation apparent between rich placer-gold occurrences and
the outcrop of a particular formation. The general association appears to be with
bedrock structures.

23. The known gold-bearing veins of the Stanley area are not considered to have
been the sources of the richest placer-gold deposits.

24. It is considered that attractive possibilities exist for intensive prospecting for
gold-bearing veins along and close to the Last Chance-Nelson Creek, Grub Gulch-Coulter
Creek, and Butcher Bench-Burns Creek faults, and also along Lightning and Slough
Creeks close to the stretches where the richest placers were mined.

25. The widespread, deep drift-cover will make future prospecting exceedingly
difficult.

LOCATION.

The Stanley area is in the Cariboo Mining Division and lies to the south-west of
the town of Wells. It is traversed by the Quesnel-Wells Road, by which the settlement
of Stanley is about 9 miles from Wells and about 45 miles from Quesnel, the terminus
of the Pacific Great Eastern Railway. The area is about 4% miles wide by about 614
miles long and lies in the south-west corner of Geological Survey, Canada, Map 336a,
Willow River Sheet (East Half), just north of latitude 53 degrees north and just west
of longitude 121 degrees 30 minutes west.

PREVIOUS WORK.

Previous geological work has been done largely by the Geological Survey of
Canada. Brief mention of the early placer operations was made by Dawson in Annual
Reports of the Geological Survey of Canada 1876-77, Vol. III, Pt. II, 1889, and Sum-
mary Report, 1894. The first work in any detail was done by Amos Bowman in 1885
and 1886. The results were published as a geological map of the Cariboo area on a
scale of 2 miles to the inch, on which was shown his mapping of the distribution of the
Cariboo schists. The map shows the axis of an anticlinorium that he was first to recog-
nize as the major structural element of the region. In addition, a detailed map was
published on a scale of 900 feet to the inch of the placer-workings and known quartz-
vein occurrences on Lightning Creek (near Stanley) and its tributaries. An interesting
feature of this map is the tracing of an anticlinal axis extending from the mouth of
