MINE OUTPUT
IN UPPER
LENHI

The most valuable production for
this cnunty during the past year has
been lead-sil7er ore from the Gilmore
district, where the Pittsburgh- daho
and Latest Out mines made an nut
put Of clean shipping mineral aggre-
eating %, 600 tons, containing about
80 per cent lead and Is oEs. silver per
ton, and in addition To this ia par
alei vein In the same vicinity there
were shipped over 4, 600 tnns oi iron
ore containing an average value OF
nearly 0z, per ton IN gold, which
also received 81 per ton premium
for It's excess iron-tluxing values.
These deposits are steep pitching

cient iiIestone formation und rlaid
by Cambrian quartZite. The deepest
development is on tne Pittsburgh
Idaho property, which Is eco feet be-
low the groupings, whore permanent
water level was encountered during
the year. Tlis, together with the
necessity of some permanent Develop
ment work, has retarded the ore pro-
ductlon. All the ore from this and
| from the Latest Out mine which has
been shipped to date has been lead
carbonate with an excess in iron OK
| ides. The deepest levels OF these
mines show the largest aud richest
ore bodies
During the year, the Gilmore 4

the properties and long crosscut de-
velopment and prospecting tunnel
