GREAT BEND MAKES
FIVE FEET DAILY
ECONOMICAL LEASERS UTILIZED
SHAFT FOR A DUMPING
PLACE
,s,eeIaI to the Bonansa.J

GOLDFlELD, June 12-With eleven
men divided into three shifts, Great
BEND is gaining five feet a day in the
main shaft. This rate of progress is
considered very satisfactory by Engi-
neer Turner in view of the growing
difficulties which beset the shaft force
Yesterday the Cameron pump was
lowered five feet and today the station
was dropped another five feet when
broken flange lost several hours time.
The water has been lowered TO
depth of 290 feet instead of 800 as
previously reported, owing to mis-
take in estimating depth by counting
the sets in the shaft. The obstruction
az this point is yielding stubbornly
and as the mass contains quantities
of broken rock ii is inferred that leas-
ers working on the 1O0-foot level econ
omized by dumping waste down this
shaft. The exact nature of the OBJ
struction cannot be determined for
several days when it will be positive
~ known whether the muck rests on
platform inserted at the 300 or that
some of the timbering has given way
and let in a quantity of loose rock.
The main location points on the sur
face have been marked with squared
posts painted white and topped with a
black circle so any visitor to the prop
erty can easily pick up the boundary
lines.
1t is not generally known that the
Great Bend estate has been opened to
a depth of 300 feet by five shafts about
800 feet apart and all connected ON
that level by long crosscut. In the
Dr. Lockhart Diadem shaft some of
the finest high grade specimens known
10 the camp were taken out in 1909.
The doctor always contended that
with money he would develop one of
the richest leases in camp but the
panic cramped his hackers. who al
lowed the lease to lapse.
Repeated shipments of high grade
ore were made by Lotus and Davis
during the first three months of 1906
These returns were so encouraging
that the management resolved not to
waste any more time in shallow work
ings but to sink TO depth of 500 feet
where il was figured the greatest val
ues would be found On the 200foot
level one of the veins averaged 20 feet
in width with all the characteristics
Of a true assure The high grade ore
showed considerable tellurium, the
first found in the Goldheld district,
and was discovered near the surface
by ] K. Davis while examining the
ground with a view TO purchase.

S. geological survey describes the for
nation in the Great Bend district as
follows THE ore consists of string
ers of quartz in slunitized andesite,
the whole being, as a rule, soft enough
to pick. Most of the ore has come
from the hanging wall side of the
ledge, but some punches have been
found next the footwall The best ore
shows small crystals Of pyrite and
sphalerite. with speck Of a telluride
