LATE REPORT FROM
TOMBSTONE MINES
The 1,oo0-foot Level has been Reached
and Station Cutting and Development
of Ore Bodies now in Progress.

The objective point which the man.
agement Of the Tombstone Consolida-
ted Mines Co. has been striving to
reach for the past four years-the 1000
foot level-has been reached, but not
without the expenditure Of some sew
eral million dollars. says the Prospec-
tor. The gigantic task of handling
vast amount of water, which has been
on an average OF 100000 gallons every
twenty-four hours during that time,
has been accomplished. The miners
now at work in the big accompaniment
shaft have reached the level. and dur
ing the next week will see the starting
of cutting out a large station at this
point. The station will be 80 feet wide
and 100 feet long y stump 50 feet deep
VIII also be sunk on the station for the
handling of water. set Of mammoth
pumps, similar to those now installed
on the 500 and 700-fo0t levels viii be
installed. one Of the pumps being or
hand at the present. As soon as the
station has been cut and pumps placed
in readiness a thorough and systematic
development Of the properties will be
commenced. II is the intention OF the
company TO push the under ground
workings into the old Grand Cenral
and Contention properties TO tap the
ore bodies that are known to be there
beneath the water level. and in which
these respective companies were work
ing at the time they We're compelled
TO shut down on account Of pumps
being unable to handle the water.
Since the installing of the new boilers
has not had the least trouble in hand
ling the water and the amount handled
has been gradually reduced from nearly
10000 10 1000. 900 every twenty-foUr
hours. and some days during the past
few weeks the amount has been re-
duced 10 below that figure Master
Mechanic sam Garrett says he expects
no trouble in the future in handling
the water as the pumps on hand and
with the boiler power now in use they
could handle considerable more water
than they have had 10 do in the past.
At the Silver Thread the work Of sink
ing the shaft is progressing rapidly and
is nearing the 60O-fOOt level. 1t is the
intention of the company 10 push the
shaft down so that the body Of copper
ore that was uncovered in the Wine
from the 500 level can be fully explored
and the determination Of its size and
the grade of the ore can be fully ar
rived at. The Wine had reached a
depth of 1875 feet from the 500-foot level
when the copper was struck and the
water at the time prevented the fur
Their working in the Wine. The collar
of the Thread shaft is some 200 feet
lower than that Of the big shaft. so that
water is encountered at a much less
depth, the old 900 level in the Thread
being the old water level. while the coo
was the level in the Contention and
Grand Central The water level in the
district has been lowered up to the
present time a trihe over 200 feet. Par
ties who have seen the body of copper
ore uncovered in the Thread. and the
formation. state that il is their opinion
that it will prove a big copper deposit.
The West Side. Toughnut. Lucky Cuss.
Tribute and Emerald are also operating
with encouraging results. At the mih
40 stamps are kept continually at work
on ore that is yielding handsomely. \
shipment Of concentrates valued at
$4,000 was shipped last week and the
regular "ciean up" Of bullion is made
every two weeks. II is asserted that
the cost Of treating the ore at the mil
is less than 81 per ton. The large ore
reserves in the various mines Of the
company will keep the mill at work
for years. II is said the company con-
templates the early enlargement Of the
mill The general conditions are most
satisfactory to the management and the
future aUgurs we'll
