On the Virginia and Comstock claims north of the head
of Hall creck, a narrow, low-dipping dyke of albite-rich diorite
holds gash veins of quartz carrying pyrite, sphalerite, galena,
and a little chalcopyrite and, it is said, free gold. Assays
of samples indicated a low content of gold. Mineralization is
reported on the north side of Goat mountain, and on the east side
of Douglas creek near its head. In both localities there are
said to be quartz-sulphide veins with fair gold values. Farther
north, near the head of Lorne creek, albite-rich diorite dykes
carry small gash veins composed, in one place, of quartz with
pyrite, galena, and sphalerite, and in another place, pyrrhotite,
chalcopyrite, galena, and sphalerite. A sample of hichly altered
dyke rock was found to carry neither gold nor silver. Some
showings in this area, it has been stated, are of fai: size and
carry gold in amounts as high as 0.6 ounce a ton and silver as
high as 13 ounces. A quartz-sulphide vein carrying good values
in gold occurs on the spur between the centre and south forks of
Lorne creek.

Oliver-Kitwanga Section

The Oliver-Kitwanga section includes the area on the ae
west side of the Skeena from Lorne creek to Kitwanga river and on
the east side from Oliver creek to Kitsequekla river. Throughout
the area the rocks are mainly well-bedded strata, chiefly argillite,
sandstone, and conglomerate, but interbedded in various sections
there is also much dacitic and andesitic tuff and probably some

lava. The dominating features is the Seven Sisters dome. The

sedimentary beds forming the top of the mountain appear to be
nearly horizontal, whereas the strata on the sides of the mountain
dip outwardly at Sais mainly of 10 to 40 degrees. ‘the core of
the mountain as exposed in the bottom of deeply glaciated valleys

is quartz monzonite. Possibly the mountoins along the trend of
