The Cheyenne daily leader. [volume] (Cheyenne, Wyo.) 1870-1884, 1875-04-08

this discovery rs especially worthy Of
attention, believing the company's
Interest will be materially advanced
by sinking this shaft through the
cap" into the opening, before aban-
doning il.
There are a number OF other pros
pect shafts sunk upon the various lOdes
owned by the Company, all OF them
looking very well, judging from the
ores taken from them.
Lastly, the Cheyenne tunnel has
been driven into the mountain Of hard.
solid grunite 40 feet, with a dip to-
ward the head of the tunnel of about
ID degrees, the vein being only about
four inches wide in the head of the
tunnel at the present line Of level.
The ore from the tunnel contains
gold, silver and copper, the latter pre-
dominating largely, the whole inter
mingled with pyrites Of iron, imbeded
in a cOarse-textured quartz Of "A CLASSY
appearance, but m~ncrysialized, and
containing considerable sulphur;
there is about I25 tons of orc upon the
dump that will pay as soon us some
mode of reducing it to bullion is estab-
Iiahed.
An attempt ut reducing this ore has
heen made in IA furnace erected near
the mouth of the tunnel, but, after
repeated experiments, / am forced to
the conclusion that this attempt has
proven a failure, practically, on the
part Of the furnace only in its me-
chanism, and its present superintend-
ent, in my judgment, being a con
tirnied mononaniGc upon the subjects
of smelling furnaces, m~etallurgy and
chemistry. These difficulties, how
ever, being easily remedicd at u
moderate cost. The principal diff
Guilty appears to be a decided def
cheney in the draft, n lack of hampers,
AT "inconvCuient mode of tapping the
furnace, and the absence Of any in
dicator to record the approximate de-
gree OF heat in the oven before and
during the continuance Of n charge of
ore in the oven. These alterations or
Improvements made, under the super
intendence of an intelligent, expe-
fenced man, / am decidedly Of the
opinion it will succeed TO the satisfac-
ton of its most sanguine friends.
1 would recommend that all future
mining operations he let by contract,
Icy the foot, to responsible, practical
miners, and the work, as soon us COM
pletcd, be inspected by a committee
before it is accepted by the Board of
Directors. ] would also recommend,
in all cases where contracts are let,
the contracting parties be required to
furnish all material.
1t is also recommended, that only so
much Of the Cempany's business, as
may be necessary to enable its EN-
ployees to carry out the designs of the
COMPANY, be intrusted TO persons not
directly interested. irresponsible per-
sons frequently make exaggerated state
mcnts, which often find their way
into the public journals, which exert
an injurious influence upon the public
mind, when reaction takes place, and
serious injury often cnsucs, for we are
continually beset by bogus mining
experts, whose wild theories, If adj
hered to, would bankrupt a nation,
much less n single corporation.
From all the data which we have
been able to collect. we estimate the
cost Of the shafts proposed to be sunk,
in round numbers, to be $500 each, or
about $4,000. This amount, il is
thought, will sink each of these shafts
to a depth of one hundred feet, and
deemed n sufficient depth to prove,
beyond II reasonable doubt, whether
these lodes will pay to work them,
