is in evidence, aud very strongly. at the
Josephine Lincoln property up Clear
Creek and a short distance west of the
city. The group comprises three claims,
the Elliott Barbour, Josephine and South
Lincoln, and are owned by the Tanquay
NJ. Il NJ. Co. The Lincoln mill has been
thoroughly renovated inside and every
part of the machinery has been arranged
SO to get the very best results. From
the time the ore is thrown into the
crusher until it comes out as concen
trates the work is automatic. In addi-
ton to the crusher, there are ten rapid
dropping stamps (1OS drops per minute)
that are kept running night and day.
There are three Wilhey tables, amalga-
uating plates, venner that is being
put in repair and other devices for saving
the values. On the ore that is now be
ing milled the loss in the tailings, as
shown by assays, amounts to only 33
cents per ton. An electrolytic analga
mating machine will soon bs installed
that will result in practically the entire
savings. The mill is under the supern
tendency of j. II. Haynes, who looks
after every detail of this branch of the
work and his efficiency accounts for the
excellent success that attends the mill
ing of the ore. He is running three
shifts of eight hours each and during
this time i6 tons of ore are run through.
There are five men regularly employ
ed in the mill and at the time of the visit
of representative of this paper there
were two additional men employed in
carrying on additional repairs and i'm
provements. The foundation for the
stamps are entirely solid concrete and
built in the most substantial manner.
In fact all the improvements carry with
them the idea of thoroughness efficiency
and competency.
The work of opening up and develop
ing the mines is under the superinten-
dency of H. M. Corwin, who has had an
experience in this work covering period
of over thirty years. He was formerly
| ly engaged in the San Juan country and
the work of driving the tunnels, cross
cuts, stoping and timbering, bear testi-
mony to his skill and practicability.
Both he and Mr.. Haynes were most
courteous and considerate of our numer
Gus inquiries. The tunnel on the Elliott
Barber claim in which work is being
done, has been driven distance of 900
| feet and 80 foot crosscut is being made
at the breast to the Josephine side vein
with fine ore in prospect. On Thursday
afternoon it was expected hat the cross
cut would break into the Josephine side
vein in the next round of shots. The
work is being done in this tunnel and
crosscut by Leyner drill. Another
crosscut is being made from the Jose
phine to the South Lincoln claim and at
depth of 200 feet below the present
workings. This has been driven 1853 feet
and the latter vein will doubtless be cut
this week. A machine drill is also doing
this work and the compressed air to run
these drills is furnished by the Stanley
company. The large body of low grade
ore on which the mill is working is now
taken from the tunnel of the South
Lincoln. This is in distance of some
800 feet and from the portal to the breast
six to twelve feet in width. 1t is all
mineralized. The slopes have only been
worked up a short distance and in some
parts of it the mneralized vein is fully
twelve feet wide. The ore is improving
in quality with development. The tim
bering is of the most creditable nature
and the mcdaniel like and substantial
manner in which it is done shows tina
Mr.. Corwin knows Just what is needed
in mine. There is enough ore nov
knocked down to run the mill for tn,
remainder of the month, while ahead il
the breast and in the Slopes there is al
unlimited tonnage to be knocked down
Mr.. Corwin has fourteen men employed
in the different workings; thus, in add
tion to the mine and mill superinten
dents, there is force of twenty one mel
now employed. The talcy ore that come
from the Josephine workings, that i
also being mined, will be mixed with tn
solid ore from the South Lincoln ant
ground together, as the results will b
more satisfactory. All of the ore is care
fully computed as it goes to the crushel
SO that the superintendent knows jus
how much ore is run through by eacl
shift. The company is certainly to b
congratulated on the good work that i
going on and the splendid management
Of the two departments.
