and contains a little pyrite, galena, and sphalerite in a quartz gangue. The
Central vein is 3 to 6 feet wide and consists of quartz with sparse sulphide
mineralization. The Green vein is 10 to 30 feet wide and consists of quartz
and calcite with practically no sulphide. The Green vein contains small
bunches, 1 to 2 inches across, of green chlorite. West of the three veins
is a northerly striking fault and a short distance west of this is a fourth
vein that has been followed by a drift adit for 480 feet. Near the portal
of the adit a winze 50 feep deep has been sunk on the vein. This vein is
2 to 3 feet wide and consists of quartz and some pyrite, galena, and
sphalerite. It branches near the face of the adit into two veins. It is in
contact with a narrow grey dyke for most of its length in the adit. Another
adit, about 300 feet north of the 480-foot adit, is 60 feet long and exposes
a 2-foot barren quartz vein.

The mineral showings on the Enterprise group of mineral claims are
above an elevation of 3,000 feet on the north side of upper Bear river a
mile or so east of the Red Top group. A vein of chalcopyrite 2 feet wide
was discovered many years ago, and the early development work, consist-
ing of an adit 100 feet long, was on this vein. More recent development
consisting of open-cuts has been done at a different place on a mineral
zone exposed at the base of a cliff.

The country rock in the vicinity of the mineral deposits consists of
volcanic fragmentals and lava flows dipping gently northeastward. A small
body of granodiorite, probably a stock, outcrops in the valley below the
Enterprise group. The granodiorite contains disseminated pyrite and
chalcopyrite and may be the source of some of the copper deposits in its
vicinity.

The vein on which the early development was done has not since been
further explored and apparently has not been traced on the surface for
more than 100 feet. In the adit it is narrower than 2 feet and is below
commercial grade.

The mineral zone exposed by the recent work has been traced
imperfectly for 1,000 feet. It consists of light-coloured, probably bleached,
voleanic rock with disseminated pyrite, chalcopyrite, galena, and sphalerite.
The strike of the zone is roughly northwest. The dip is not known with
certainty, but is probably northeastward at a low angle. The thickness
of the zone is unknown. No ore has yet been uncovered. High-grade,
silver-bearing float is rather plentiful in the talus below and probably has
come from the mineral zone or from some undiscovered mineral body
higher on the mountain.
