Vaiueu at over Sl,OUOOOO was mlneu Dy
the Consolidated Mines company in
March and a new record established
for the tonnage treated by that COM
pany in any one month. The value
OF the product was exceeded only once,
in March a year ago, when the new
mill was just attaining its full stride
and was called upon to handle large
tonnage of high-grade ore that had
been exposed in developing the then
newly discovered ore-shoot in the
Clermont. Last month the mill treat
ed 26,617 tons of ore. an average of
SCI tons daily, with an estimated gross
value of $l,015,000 q recovery of ap-
proximately $950,000, total costs Of
100000 and net profits to the company
of $730,000 The figures are estimated,
but in the past the managers esti-
mates have invariably been well with
in the final returns.
The principal tonnage for the mill
is now coming from the Clermont
workings. which are yielding about 800
tons daily. The Mohawk, Combine
tion and Red Top mines are each pro-
ducing nearly 200 tons daily. The pro-
duction from the Clernont is distrib-
uted Throughout the various levels and
intermediates, but the chief source Of
supply has been the series OF large
slopes on the 750-foot level. At this
point the sill floors have been extend
in rich ore. and It is said that ST.
100000 worth of high-grade ore was
taken from this drift in the course of
regular development work. For
width OF from eight to twelve feet the
ore averaged around $500 ton and
this is used TO mix with low grade ma
terial In order to maintain the desired
quality for reduction. The same ore
body is exposed on the 600-foot level
and raises from the $50 have con-
nected these two levels and are all in
ore.
OPENS ORE SHOOT
On the 1O00-foot level of the Cler
mont the development continues to
open up the large ore shoot and at this
depth the showing is even better than
at the 900 level, where the ore is ex-
posed for 300 feet in length. Average
samples of the ore hoisted from the
1000 level have been running above $50
a ton and the entire ore body Is ap-
parently OF excellent milling grade. AT
a distance of $50 feet west of the
Clermont ore shoot the Mohawk vein
is being further opened up ana ls
making an excellent showing with
over eight feet of good ore. This de-
velopmenfE Is egarded by the man
ager as highly important in demon
strating the continuity at depth OF the
rich Mohawk ore. 1t Is thought that
this ore shoot will be found to form
junction at greater depth with the
Clermont tunnel, and II this theory
proves correct there is hope of finding
at the point of juncture deposit or
large size and high value.
The annual report of tho Florence
Coldfeld Mining company, covering
operations in 1909 has been mailed TO
the stockholders, accompanying diVi-
dend checks for the first dividend
this wear In this President Thomas
q. Lockhart shows that the company
is now operating on broad scale and
The mill which has passed the expert
mental stage, Is proving highly sue
cessful In the treatment OF ore. during
last year the company treated 34,S24
tons of ore of the average value or
sts42 a ton and shipped to the smell
ters ia tons of high-grade ore valued
at S2S7.54 a ton. The expenses amount
ing to 5000, $50, were high, as this item
included mill construction, marketing
ore and a large amount OF new deVel-
onn1ent work Net profits for the year
were S232.O5O and two dividends were
maid, in June and October, aggregat-
ing 100000.
FLORENCE DEVELOPMENTS
Development work on the Florence
has been confined chiefly to territory
within $50 feet north and 400 feet
south of the main shaft and for the
greater part above the S50-foot level.
"a
the old lease workings with the main
shaft and some of these are 500 feet
deem and have cut through ore bod
les of excellent character but little Ell
fort has yet been made to develop
these ore shoots below the $50 level;
The, main shaft Is now pelhg enlargeo gaa
to three compartments from the 68O
ia | to the surface and upon the COM
M ION of the work all the veins OF
IN neighborhood will be thoroughly
n lored at greater depth. The main
4 renee vein is, in places, 100 feet
r. but the ore occurs In lenses
shoots of irregular size and value
tn bughout this vein Ore Is exposed,
no, veyer, almost continuously for 1000
feet north and south.
A remarkable Improvement is shown
in the results Of ore reduction. Dur
ing the first months of operating the
mill a saving was effected of only
es13 per cent of the gold content, but
This has Seen improved upon contin-
,,atlv until at present the average
saving is 95.05 per cent. The mill has
proved it's efficiency In handling sue
eessfully ore of widely varied kinds
and during the past year it has treat
ed nroducts from every part of the
mine. sulphides, oxides, hard and soft
orc high-grade, carrying tellurium,
and-low- grade ore from the old lease
dumps have all been put through the
mill The plant was nrSt conslrucleu
as a 2O-stamp mill, but an auxiliary
battery of 20 stamps was installed as
a measure of precaution against ac.
oident Later experiments indicated
that the capacity could be increased,
as we'll as the efficiency of the plant,
with comparatively small expense; and
in Nav last additional equipment was
Installed, Including four Card coneen--
traitors, four amalgamating plates and
another tube mill, resulting in an in
cease of so to 60 per cent in capacity
which is now from 15O to 100 tons
daily. ,.DDs,DUs
ore has been exposed in workings
from twenty different shafts on Flor
ence territory, but from only two
shafts has there been any extraction
sar the mill All of the former leases
anerated under agreements providing
tbat ali ore valued at $40 ton or less
sbould become the property of the
1Fl6rence company Large quantities
af are of this character remain IN the
aid lease workings or on the dumps
