at elevations from 6,500 to 6,800 fect there are a number of
other deposits. The slope of the mountain here is gradual, the
rocks are badly shattered for a depth of more than 15 feet, and
the whole area in =o cases remains covered both winter and
summer with a blanket of snow. Four veins have been opened up
and others are indicated by float. Three have been traced by
pits at intervals not exceeding 200 feet, for, respectively,
1,500, 800, and 700 feet. They strike southeast up the slope
toward the peak and dip about vertical, All are curved and one
changes direction by 40 degrees. Lay states that the vein
traced for the longest distance contains massive sulphides in
lenses, 1 to 30 inches wide, for at least 1,200 feet, and that
galena and sphalerite at the lower end change to arsenopyrite,
sphalerite, and chalcopyrite at the upper end. The other veins
are similar. A width of 6 feet showing bands of sphalerite,
chalcopyrite, and galena was noted in one place. An assay on the
lower part of the main vein for 2.5 feet gave: gold, 0.14 ounce,
silver, 90 ounces, a ton; lead, 64 per cent; zinc, 0.2 per cent.
This is representative of the part of the vein that contains much
galena. It is understood that the other parts of the veins are "
higher in gold.

The structure of the rock where the veins occur is

complex and includes a sharp anticline on the northeast side and

an open syncline to the southwest, both of which plunge steeply ie
ie
to the southeast. The rocks are older than the Skeena formation Bt
a
and their structure has no bearing on the dome structure of the ae

mountain related to the intrusion since they may have been

greatly deformed long before the doming. The veins cut across the
formation in places at right angles to the bedding and it is clear
that the main veins are not related to the structure of these rocks.

They probably occur in fracture zones of the common type found on
