are not known definitely, but it is reported that good silver
assays were obtained and possibly a good gold content may occur

in some sections such as those high in arscnopyrite.

Other Deposits. On the north side of the valley at an elevation
of 3,000 feet, 500 feet above the creek and less than 15 feet
below the base of the Skeena formation, a series of irregular
stringers dipping from 10 degrees west to vertical carry galena,
sphalerite, pyrrhotite, pyrite, possibly chalcopyrite, and other
minerals in a quartz gangue. The basal beds of the nearby Skeena

formation and probably the contact have approximately the same

strike (north 10 degrees west) as the stringers, but dip 70 degrees

east. The rocks of the Skecna formation are intensely sheared,
especially along the coaly horizons, which are now graphitic.
The fractures appear to be related fairly definitely to this
contact, and were probably developed sine it because of
differential movement between the two formations.

Along the north side of the gulch just west of these
deposits and still near the contact other similar stringers are
reported, one or more of which is reported to be high in silver.
Good specimens of pyrite and chalcopyrite are reported to come
from a good lead on the north side just above the junction of
the two streams. Higher up there is said to be a flat vein
containing tetrahedrite, which carries 2,000 ounces in silver,
and still higher a considerable deposit of pyrrhotite and pyrite.
A poorly mineralized gash vein is said to occur between the two
streams below the glacier. The presence of pyrrhotite and pyrite
in the Lake Kathlyn coal mine has already been noted.

TOBOGGAN CREEK. Toboggan Creek valley as far up as Schufer lake
is in the Skeena formation which in the upper part of this
section strikes parallel to the valley and dips steeply north,

though in the base of the valley the dip appears to flatten and
