Developments From Main Shaft
At point nearly opposite the
western end of this surface outcrol
shaft has been sunk and has reach.
ed depth of 400 feet. At the 10O
foot level the ledge was prospected
easterly and westerly for short
distance, disclosing strong ledge
highly mineralized. At the 200 foot
level, at which point the ledge was
intercepted by the shaft, a better
grade Of ore was found in drifting
eastward, but only small quantities
we're found in running westerly, until
the ledge had been followed some
225 feet. where some ore was en-
countered.
Main Ore Shoot to East
In the 400 foot level but little ore
was found In drifting westward, and
that only in punches, and yet the
ledge was shown to be strong and
we'll defined. as far as prospected, a
distance of 285 feet. Running east

passed through ore for some SO feet,
at which point, owing to the great
width OF the ledge and In conseQu-
ence necessitating a great deal Of
timbering, 1t was deemed best to get
away from these conditions and cut
into the more solid formation, north
of the foot wall side Of the vein, thus
leaving the vein and its contents to
the right and in an unprospected
condition. The drift was continued
away from the ledge for consider
able distance; occasionally, however,
cross cut was run from this drift to
the vein and across it, and in every
instance it was found to be strong
and well mineralized. The last por-
ton of this drift was run on the ledge

fine grade OF galena.
Lowest Workings Show Best Ore
A shaft was started on the ledge in
this level about so feet back from its
eastward face and sunk to a depth OF
200 feet below the 400 foot level
The first drifting from this shaft was
run at a depth of SO feet, prospect
ing the ledge in both directions, with
the most satisfactory results from
this exploration. Following up the
operations through the 500 and $50
foot levels, l find a larger quantity
