That mining operations are to be
pushed in the Warren District with Il
Sigor never heretofore known is eIi-
denced by the extensive plans which
have been formulated by the Copper
Queen company some OF which were
outlined last week by Joseph HUds-
son, superintendent OF mines for that
company ana which are OF the keen
est interest 10 the people OF this dis
trict and all Interested in mines or
mining properties therein. These
plans contemplate some changes OF
mining methods. new work OF cNpiof-
alton and development new machln-
cry and new buildings. Some sweep
Ing changes OF methods in under.
ground work will BE employed and
the new plans will work 10 the hene-
n of both company and operatives.
adding TO economies for the former
and 10 comforts for The latter.
Will Practice Top Slicing
The system OF mining known as
slicing has not prevailed in this camp
where ore has generally been STOPPED
out. although recently there has been
some top slicing done by the Copper
Queen company. This method Is nov
practiced mo-e extensively and uc
results will be watched with inter"s-.
Captain 'HOdgs9n states that tpp
'slicing is TO be put in operation at the
Gar and in this connection says thaI
circular concrete raises are 10 be put
in. starting from the 400 level ana
extending 200 Ieet TO the zoe level
Through these raises the ore VIII De
brought to the 400 level and then
transported by trans TO the Sac'd-
mento shaft for hosting,
Ton slicing consists OF taking out
ore from above and leaving a flooring
which is dropped to the flooring De
low. This is again done and the sec.
ond flooring falls as did the iiTst

The slicing method has been sue
cessfuIly practiced in numerous us
tricts and is now so practiced 70 some
extent in Cananea. In many install
ces il has been found that TINS vas
the most satisfactory and economical
method that could be employed ana
il is believed that such will be found
TO be the case here, especially at INC
point where ii will be undertaken
where the ground is soft and moist.
This is the most important event IN
mining circles OF the district thai

New Development - Planned
In addition to the work ~ putt,hs

opInent work is soon 10 start IN
this is Included a further sinking OF
the silver Bear shaft, one OF the hOs'
recent developments undertaken by
the company This shaft was put
down zoe feet and the showing thal
has been obtained were Is so en-
couraging that it was decided 10 20
down another ZOE feet
Further sinking is also 10 be done
at the Uncle Sam where fine boey
OF ore was developed as has been
mentioned in the Review on several
occasions. This shaft is now on the
200 level and will 20 down 200 iee'

New Machinery Coming
For the Sacramento a new hoist has
been ordered and the work Of prepar
