Mill IN Good Condition.
The year commenced with the ncces-
sary changes at the mill. such us chang
ing trommels. jiSs, classineTs. etc, In or
der to get the proper classification to
meet the requirements OF a new mill. to
handle certain class OF ore and obtain
the best possible saving These changes
nave been made, and the mill is now in
yer! good condition, Its saving being as
close as practical by concentration.
Amount of Ore Milled
There have been Installed three sets
OF scales for weighing crude ores and con-
centrators on jigs and table floors en-
abling us to determine exactly our per

shines Jig have been added to the mill
equipment There havc been mllled IL $685.

which produced 2956.15 tons dry of con-

gross value Of Ss5 &c. effecting saving
OF ,S1a per cent and on a concentration

Improvements of Year.
During the year. as the report states
the company built a brick assay furnace |
