sulphur and iron. These ores form
in assures, flats and pitches, and
there are large bodies disseminated
In the rock. Large bodies of lead
are also found in boulder formation,
in pieces ranging from 50 to 1900
pounds IN weight. Copper There
are bodies of copper ore in the dis
trict which can be operated with
o. oft, the Indians before the advent
of the white men having smelted
large quantities of 1t and the ruins
of their furnaces are yet to be seen
at many places in the district.
Sulphur-Large deposits of pure
sulphur are to found at various
places in the district, notably at
Linden where it is being profitably
mined.
The ores are found at shallow
depths, the averages being eighty
feet in some localities and 100 feet
in others and there are still others
in which they occur from the grass
roots. The method of mining is
simple and comparatively mex
penslve, no more than $50, 900 to
$50, 900 being required to prospect,
develop and equip these mines with
concentrating mills and machinery
and to bring the plant to a point of
successful operation. The average
time required to develop these
mines to this point of productive
ness varies from nine TO fifteen
months. Some 400 mines IN the
district have been developed or are
in q process of development. Of
this number 1O5 have been equipped
with concentrating mills within the
past three years, a majority of
them during the last eighteen
months. There are now fifty ad-
ditional mills contracted for this
year.
Eight years ago there was but
one small mill in the entire district
and that was on the Raisbeck Mine
at Cuba City. It will be seen by
this that the district is in it's in
fancy. The zinc output for the
year 1907 was So, 100000. Upwards
OF $50, ZOO, 600 of lead and zinc,
principally lead, had been recovered
in the district prior TO 1908. This
recovery was accomplished by the
most primative methods known to
mining, the upper runs for lead and
for the zinc carbonate, whi:h were
found from twenty to forty feet
below the surface and above the
water level. The discovery of large
bodies of zinc ore In the lower
raudoms by means Of churn drills
encouraged the installation OF
modern mining machinery during
the past three years, and work has
been vigorously pushed over a
limited extent of the mineral field,
Mining these ores is very profit
able and there are now more than
two dozen mines in the district
which have paid their owners from
five to fifty per cent monthly
dividends on their respective CAPT.
talization. To illustrate, one mine
has paid $3.50, 900 on its capital of
$50, 900, and another has paid 1910,
900 on a capital of $50, ZOO, each
within the past three years. Apart
from this, these mines have each
paid $40, 900 for equipment OF its
plant and each now has a good
reserve fund established. These
instances furnish only a vague
idea of the great profits to be de-
rived from lead and zinc mining in
this district
VALUABLE BY-PRoDUCTs.
In addition to the lead and zinc
products of these mines there are
many thousands of tons of other
products which annually are treated
as waste, because as yet, no provi-
sion has been made to save these
by-products
This is important because some of
these products if properly cared
for would be of greater value than
lead and zinc solely for which the
mines are now being operated.
Some of these valuable by-pro-
ducts are
Iron SuIphide-Thousands of tons
of this mineral are found in con-
junction with the zince ore. By
the employment of the proper pro-
cess the iron in this sulphide can be
made a valuable product. Sulphuric
acid, for which there is an ever in
creasing demand, is also manu-
featured from this product. For
handling this product there is now
but one plant IN the district and it
is located at Mineral Point, Wis.
Oil Rock-Thls rock is found in
every zinc range in the district,
