Driftwood Area
Driftwood area is a rugged, mountainous section lying
east of Bulkley valley directly opposite Hudson Bay mountain.
It is bounded on the north by an extensive, relatively low area
end on the south by Carr (Canyon) creck. Most of the section is
included in the Driftwood Oreck map-area, which was mapped and

described in detail by Hanson. The rocks are largely sediments

and volcanics and include tao series of more or less massive

volcanics and two of bedded rocks that are largely sedimentary.

All of these rocks are cut by a number of stocks and dykes of
diorite, quartz diorite, and quartz porphyry of different Ages.
Near or within the intrusive areas and in places clearly associated
with them are mineral deposits.

"All the mineral deposits occur as veins, mostly narrow
end comparatively short quartz veins. Their silver content,
however, is in some instances very high, and several of the veins
could no doubt be mined on a small scale with profit." The gold . i
content is high in only a few of the deposits. “Copper, lead,
and zine are present in considerable proportion in some of the
veins, but values in these base metals merely supplement the 4

value in silver. With the present means of transportation only

surprising to find properties idle which would have considerable

merit were they more favourably located. It is believed that

many of the mineral deposits are essentially local in origin,
and that the metal-contributing sources were of smail volume.

It is expected, therefore, tuat small mineral deposits will be
the rule. The sporadic distribution exemplified by lens-shaped,

discontinuous veins is probabiy cue largely to the diverse
