nave Deen pldnueu LOT the near lu-
lure. Seventy-five per cent of the
stock of the Orizaba is owned by
the Diamondfield Black Butte Re-
organized Mining company, with Of
fices in Goldfield and owning claims
in the Diamondfield district.
The old steam surface plant, con-
sisting of one 20, one 40 and one
S0-horse power boiler, steam
hoist, one No. and one No. 8
Cameron sinking pump, a two-drill
air compressor and a small under
ground hoist, all in delapidated con-
dition, will be abandoned. The use
Of steam power and oil fuel will be
and a modern distilate
or gasoline plant will be installed.
The bunk house, boarding house
and other buildings on the proper
ty are in good condition, according
to J. X. Turner, E. NJ, consulting
engineer for the Sprague interests,
who recently returned from an in
spection of the Orizaba.
The company owns nine full
claims in one group, aggregating an
area of 1870 acres and in various
workings has done 1900 feet of de-
velopment work, consisting of $50
feet of shafts, 900 feet of drifts, 80
feet of crosscuts, so feet of raises
and 12O feet of wines. The main,
or No. l shaft, is believed to be 12O
feet deep. Mr.. Turner stated that
he could not get below the S5-foot
level, as the water stood at the 95-
foot point. Shaft No. 2 Is 80 feet
deep.
The first level is 65 feet below
the collar of the main shaft and the
second level is 20 feet below the
first. The shaft is sunk in or near
the footwall of the vein and dips
at the same angle as the vein.
The drift on the 65-foot level is
$50 feet long. One hundred and
fifty feet is driven east and the re-
naming 400 feet west of the shaft.
The drift on the S5-foot level is $50
feet long and also extends east and
west from the shaft. The west
drift is 220 feet long and is caved
beyond 10 feet from the shaft.
The main winze is sunk 12O feet
west of the main shaft and on the
S5-foot level. 1t is said to be 100
feet deep. In a small winze at the
end of the S5-foot level, east, Mr..
Turner found quartz of promising
The mine workings were sampled
wherever the drifts exposed the
vain and results obtained from 28
show an average width of
three feet. the ore assaying 1926
per ton. This average, according to
Mr.. Turner, included some samples
that were below mill grade. In ex-
tracing ore for milling, bodies of
lower grade than SO per ton can be
left in the mine and an average of
all samples assaying over SO per
ten showed the vein to have an av-
crage width of three ane one-half
feet and to have a value of 1892
per ton. All assays were figured
on basis of 81 per ounce for sill
yer and the small gold content was
not considered.
Mr.. Turner found the total value
Of three dumps to be $44,73O. Ac-
ccrding to him, development shows
no ore technically in sight in the
mine, but ore that may be classed
as probable" was found between
the 35 and 65-foot levels, both east
ard west of the main shaft. This
ore is estimated to be worth $6,-
030.50. From a point 90 feet west
Of the shaft on the S5-foot level
and to the 65-foot level there is ex-
posed probable ore" of an estimat-
ed value of $8587, making a total
Of $14,617,50.
Great difficulty has always been
with water and Mr..
Turner states that this has been due
to poor equipment and that with
the new and ample equipment which
will be installed there should be no
in handling the water.
The nearest railroad point to the
mine is Millers, 38 miles south
over a good wagon road, en- which
supplies and ore can be hauled
the year. However, the
Isolated position makes the ques-
Lion of ore treatment an important
one. Mr.. Turner stated that it
would be useless to offer an opin-
IN regarding a method of treat
