There is also an assay Office, an Office

Wood is used as full. The entire cost
of the plant approximates $50, 600. Some
thirty tons of ore are crushed each day

in development work underground, so
that instead Of the mine being exhaust
ed. its reserve is being continually in
creased. In fact. but little ore is now
used that is not obtained directly
from development work.
Above the mill, on the hillside, is a
I tank holding $4,000 gallons of water,
which is kept as a reserve and for pro-
lection in case of fire. There is a com
plete system of trackage through and
about the mine and mill and TO the
wood yard, where a sufficient amount is
corded up to last several months.
Has Plenty Of Ground.
The company's holdings include 100
] acres of land, situated mostly on the
west slope Of the hillside. Tunnel and
shaft work has been done to an extent
of over 1000 feet, and practically all OF
this work has been through ore. The
first shaft is on the lower part Of the
ground. the second, and present. work
