Development


canyon slope of Squaw creek with
its lower adit portal just above the
valley bottom. 1t is opened on mine
levels by four tunnels from the sur
face to a vertical depth of 800 feet.
All the levels are connected by raises
and a main transfer chute, great part
of which is in solid rock, makes it
possible to convey the ore by gravity
from the upper level and draw 1t out
at No. level without rehandling,
making the mining operation compare
lively inexpensive as far as transpor-
tation Of ore to the mill is concerned.
Ore Reserve
The ore bodies have been explored
in past operations Of the property ex-
clusively for high grade, shipping
mineral of which its is conservatively
estimated million five hundred
thousand dollars worth has been pro-
duced, large proportion Of this was
marketed under the low metal prices
prevailing prior to 1902. AS a consc-
1uence of this extensive exploration
If the mine approximately $4,000 tons

erade ore bodies are as much IS SO
