In the main the stringers are at oct only a few
inches wide both within the central altered section and beyond.
They follow in the main straight fractures but show no sy stem-
atic arrangement; they are most commonly vertical but may be at
any angle. Attempts have been made to work the stringers both
within the main deposit zone and beyond, but so far no vein has
been disclosed that seems to offer hope of making ore. Within
the main deposit zone on Bob creek the stringers in places carry
sphalerite, pyrite, and lesser quantities of galena and possibly
arsenopyrite; on Buck river they carry all except the last, and
tetrehedrite. Tests by the Mines Branch, Ottawa, on three
small samples (two of decomposed vein matter assaying low in
gold) failed to find free gold. Tests by the company engineer
and others have shown free gold, and small flakes are reported
to occur on the walls of Bob Creek canyon. Much of the gold in
the veins probably is not free or is very finely intermixed with
the sulphides. There are some differences in the character of
the stringers; probably they were formed at different times,
and contain different minerals and values. Thus some sections
with a certain type of stringers might go much higher in gold
or silver than others.

Stringers beyond the main deposit zone carry the same
minerals, pyrite, sphalerite, galena, and quartz, though they
may have somewhat more galena and quartz. Assay values of one
(1,000 fect below the end of the canyon) showed 7.8 ounces of

silver and 0.23 ounce of gold, and enother2 a trace of gold and

42.5 ounces of silver a ton, with 7 per cent lead and 7 per cent
