MASS SHOULD
HAVE GOOD YEAR
OUTPUT is TO BE INCREASED
AND SOME PROFIT MAY eE
REALIZED FROM oP.
ERATIoNs.

At Mass Consolidated during l9i
attention was directed pcFslstcntly 20
wards opening new ground. with n,
pronounced effect To keep up larg,
shipments The results were -grotify.
ing There is now guile a large ;on
mage Of ore reserves opened, and th'
current volume Of shipments. about O.,
tons daily. viii doubtless be Increased
gradually during 1912 untl a daily
output Of 500 TO zoo tons Of rock rs
reached.
AT the same time development viii
be carried forward AT a rate TO bring
much more new ore into sight than is
extracted. 50 the volume OF shipments
can be still further enlarged at viii.
The policy now is 10 discard sufficient
low-grade rock so that the weld Of
rock shipped To the stamp mill is about
is pounds Of copper per ton Of rock
At present thls is regarded as the
most economical method.
Operations are confined to shaft T.
and shaft c and Il Is In the iauer or
most westerly operations that the lead
ing developments have taken place
Shipments from shaft b are at the rate
of l2O tons daily and from shaft CI
about 200 daily.
