SIX GHURN DRILLS
IN MIAMI DISTRICT
Exploration Work Promises
Much Additional Ton
mage Shortly.

Globe. Ariz. March 1s.-Besides the
work Of actual mining and underground
! development that is being carried on
/ in the Miami district another sign Of
{ the interest that is being taken by out
side capital is the large amount of eN-
/ ploration that is being done by churn
drnllng- -FOUR different companies are
conducting this kind of exploratory
work, with six churn drills in cOntinu-
Gus operation The Miami Copper com
pany Is working one drill northeast Of
the ore body in the vicinity Of No.
SHAFT, on ground whose surface indica-
lions are considered very favorable for
I the development Of another body OF
ore The New Keystone Copper com
pany is operating one drill northeast
Of the shaft. The Southwestern Miami
Development company, whose property
lies in the southwest Of and adjoins
company, is running two drills and in
tends to add another as soon as pos
sible- The rLewisOhns, who have an
option on the Barney group lying to
the west Of. and adjoining the Live
Oak, are operating two drills. In ad-
ditiOn to these, there are possibilities
Of others being added IN the near
future. 1t seems reasonably certain
that considerable tonnage will be
added to that already blocked out IN

EnIarging Live Oak shaft.
The work OF enlarging shaft No. I

three compartments, is proceeding rap
Idly and IS expected to be finished
this month. It is being done by three Z
crews Of men raising from as many
points in the shaft, with three shifts
working. The surface equipment is
being erected at the same time. The
two 80 horse power boilers have been
br1cked in and the Is by 20 double
drum hoist is being assembled. Devel-
