places very rich, tetradymiteo-gold deposits ocevr in sheared zones
and in open spaces in massive volcanics. Bedded rocks, including
argillite, conglomerate, greywacke, and tuff, belicved to be part
of the Skeena formation but not readily distinguishable from older
rocks, occur dipping into the hill just above the deposit and in
small patches dipping toward the valley near the deposits. The
deposits, therefore, are probably largely confined to the crest
of a minor fold which trends south 40 degrees west up the slope
of the mountain toward the peak. Any continuity of the favourable
zone is very likely to lie along the trend of the fold. The
greater part of the anticline, including much of the crest and
northwest limb in the vicinity of the deposits, has een eroded
away. Farther up the hill more of it may be preserved. However,
the deposits may owe their localization to a nearby feeder
fracture and the mineralizing solutions may not have migrated
far along the anticline. Other shear or fracture zones may
also have carried the solutions and may also have been mineralized,
as is indicated in the workings, but nothing suggests the presence
of fractures that might carry valuable deposits. Field and
microscopical studies did not offer a definite clue as toa
possible nearby source for these deposits nor was there any
definite suggestion as regards relationship to intrusive bodies.
Doming of the rocks locally may have some significance and it is
clear that the deposits were formed after most of the structures
were developed and, therefore, are probably of about the same age
as the other deposits on the mountain. Ali may be related, but
the mineral association certainly suggests some difference.

‘The ore occurred in a number of small pockets scattered
mainly for about 200 feet along the steep slope (over 50 degrees)
of the south wall of the valley at elevations between 4,050 and

4,175 feet. The pockets in some cases vielded loss than one ton.
