Mines - Independent Group
The original
Independent group of six claims was located
Independent
Group in 1919 by the Fitzgerald brothers, of Stewart. The property is situated on
the steep slope west of Bear River and
bounded
by Goose, or Fitzgerald, Creek and the ice cap
on
Bear River Ridge.
The Big Casino and Red Cliff
properties
are adjacent to the north and east boundaries
of
the Independent. The area is presently accessible only by helicopter. The country rocks are red and green Hazelton assemblage volcanic
conglomerates and breccias which trend northerly and dip steeply west.
The main Portland Canal
dyke swarm passes through this section and has divided the country rocks
into
thin panels and wedges. Fitzgerald Creek marks a major normal fault zone where
the east side has moved down and north relative to the main ridge.
At least five veins or
mineralized zones have been explored by trenches, several adits, and diamond drilling. The old camp is
completely demolished and
most of the trenches are filled in, the main adit at elevation 2,950 feet on No.
I vein is still
accessible,
but the small adits on No. 3 and 4 veins in the gully a few hundred feet to
the northeast, which were presumably driven from the old snow level, are
completely out of reach at present.
No. 1 vein, trenched at an
elevation of 3,250 feet and traced by a drift for 700 feet, consists of a northwest-trending, steep, east-dipping, irregular,
quartz-barite-jasper breccia zone containing erratic pyrite, chalcopyrite,
sphalerite, minor arseno-pyrite, and pyrrhotite, as well as angular fragments of
weakly bleached wallrocks.
Silver values reportedly were as
high as 10 ounces to the ton and the other metals were negligible. In 1928, in spite of poor diamond-drill results, a
second adit at an elevation of 2,760 feet was initiated on the No. 1 vein, but operations
ceased at the
end
of the year. Work has not been recorded on the property since then, but evidence of recent diamond drilling above the main
showings at about
3,400 feet elevation was noticed in 1965.
