Star Mine.
The Star mine, owned by Messrs
Finch, Campbell. Moffatt and others, is
in Grouse gulch at the foot of the spur
between its principal forks. 1t Is Of
interest because it shows what are
believed to be the westward continu-
ations Of the Morning and You Like
veins. It is developed by tunnel
about $500 feet long and by several
very extensive drifts.
4 The sedimentary rock penetrated by
these workings Is quartzite, some, OF
which is extremely hard and thick
bedded and all of which probably be-
longs to the Reyett quartzite, The
drifts cut several small bikes Of a
gray porphyry and dark lamprophyre
both of which probably bear gen.
etic relationship to the monzonite that
is exposed near Gem, about two miles
to the northwest. The general dip is
about 20 degrees east. but the strike
is extremely variable. Fissures, most
~ OF northwesterly trend, are very
numerous.
The best showing Is in the Morning
vein east Of the main tunnel, which In
places contains feet of fairly good
concentrating ore A widening OF the
vein is apparent in some places where
It Is Joined by other assures formed
prior to the naturalization and some
vein material makes off in assures of
this character In the easternmost
accessible workings the vein seems to
have divided into several small
branches. A vertical fault. converging
westward with the vein has cut 1T off
short distance east of the tunnel, but
its westward continuation Is believed
by Mr.. Moffatt to be represented by a
vein found at the face of the. tunnel
The study on which this paper Is bas-
ed hardly suffices to prove or disprove
this supposition. The fault, however
though very distinct, is probably mol
of large throw, for 1t has displaced a
porphyry dixie which 1T cuts only anou'
20 feet. A long drift in the genera
direction of the Morning vein west o.
the tunnel has not revealed any com
mercial ore. 1t follows here one ano
there another of system of sinuou'
branching assures. among which 1t Is
difficult to identify the representative
of the Morning vein. The conditions
along the drift that goes westward or
the supposed You Like vein are some
what similar although this drift fo'
lows a straighter and more definite
Ifissure along which some faulting h1'

The ore from the Morning vein con

chiefly of quartz with very little slider
lite. It is accompanied by SINAI
amounts of sphalerte and pyrite. tn
lscarcity of siderite here is a notabl

that this mineral becomes less abund
