The Volunteer Mine


deal of surface work has been done and there
are several small shafts from 10 to 20 feet in
depth along the line of the lead. The main
SHAFT which has attained depth of IS feet,
was started at point where the groupings
looked favorable and has demonstrated that
there is very large ledge of ore running
through this which, although not of remark
able richness, is Of a uniformly good charac-
ter and is at all times we'll defined. In the
bottom of the main shaft the ledge formation
is about - feet wide, s feet of which is free
milling and feet black ore carrying consid-
cradle manganese. A lot taken from the
body OF free ore, not sorted but shipped as it
came out, milled between 40 and so ounces
in the Silver Bow mill, and am told that 80
per cent. OF the assay value was saved. A drift
has been run east from the bottom of the
| shaft on the ledge, the face of which shows
about 7 feet of free ore and % feet of black
or manganese ore. In the black ore at this
mine there is not sufficient manganese to
prevent its manipulation by milling process,
the percentage, although the rock is heavily
stained, being very small. Little prospecting
has been done in this section although some
very rich ore and float have been found on the
that the Volunteer will prove one of the most
valuable properties in the camp. 1t is full
claim 1900 by 600 feet, and, besides the main
ledge, several streaks which are undoubtedly
spurs of good ore have been found on the
surface. Little or no work has been done OH
them.
The Maximilian Mine,
Owned by the Silver Bow Co., is situated
west of Park street. The ledge on this mine
is, as rule, narrow but of a high grade,
bearing in many Of its characteristics strong
resemblance to the Morning Star lode. The
shaft is down IS feet following an ore body
varying in width from II to 80 inches. From
the bottom a drift has been run east on the
ledge ITO feet, where the ore body is wider,
being from to 4 feet, but not so rich. The
drift west from the bottom is in about Is feet
and the face shows a nice looking streak of
high grade free ore. They have struck water
in the bottom of the shaft and it will there
fore be impossible to sink much deeper this
winter
The CarI0ttis Mine,
Owned by the SILVER Bow Co., adioins the
MaXimiian on the west. The shaft is down
| 60 feet, following the same chute of rich ore
encountered in the adjoining claim. The east
| drift from the bottom is in about 65 feet, the
| ledge in this drift rnnning from inches to %
| feet in thickness. The Intention is to make
|
imilian, the two mines at present being run
in conjunction. This will greatly facilitate
their working. 1t is unfortunate that the
| water is so troublesome in the bottom, as the
prospect at that point is very fattering.
Large quantities of high grade free ore have
been taken from this claim and great deal
of rich ore was also extracted on and near
tho surface from several of the mines sur
rounding it. Both the Carlotta and Maxi
milan are at present leased to one party, who
should certainly be making a coed thing out
| of them. The ore is worked mostly at the
Silver Bow mill.
| The FredOnia Mine
Has been leased by Mr.. Williams, of Clark 5
smeter, and prospecting is at present being
vigorously pushed. They are developing a
heavy body Of manganese ore feet in width
large quantities of which are being extracted
and shipped to the smelter for reduction.
There is also great deal of tree ore in sight
in this mine above water leYel, the ledge car
rying full body Of it on the hanging wall
from the surface. At the
Aurario Mine
They are still sinking in a fine body OF high
grade free ore. This mine is turning out
better than its owners anticipated, the pros
pect being so fattering that as soon as the
body of free ore upon which they are at pres
ent working in the Cora is exhausted the
whole force Of men employed on that mine
will be transferred to the Auraria it being
thought that there is sufficient ore in sight to
keep the Burlington mill running, which the
Cora has hitherto.idone. Another fact which
assures the success of this mine is the exceed
ingly high grade ore, the ledge in many places
averaging as high as 200 or. per ton. At the
Belle Mine
They are sinking shaft No. 2, which is now
down between 20 and 50 feet. The slopes
between shafts No. and 3 are yielding
largely and the ore body upon which they are
drifting from the bottom of shaft No. con-
tinues fully as wide and rich as when last
reported, the base ore particularly on this
level being exceedingly rich. At the
Colusa Mine
The main shaft is down 165 feet, and at the
present little or no trouble is experienced
from water. The ore body in the bottom is
looking finely, and some of it is wonderfully
rich, showing large quantities of native sill
YER, and assaying high in copper The ledge
in this mine is second to none in the camp
for size and strength of formation, and the ore
body has been steadily improving in richness
from the surface. The flow OF water is not
nearly SO heavy as at dept of 20 feet and
drifts east and west from the bottom of the
shaft will open a body of ore whose size and
richness will in all probability fully repay the
owners for their enterprise in taking hold of
this property. The ore body as it isnow opened
can be mined very cheaply. The new smelter
will manipulate the ore, and another large,
paying mine during this coming summer will
undoubtedly be added to our list of bonanzas.
At the
Mountain Mine
They have been busy during the week put
ting 4 pump in the main shaft There is a
heavy flow of water TO combat in this mine,
the whim at times hoisting four barrels of
water to one of ore, which is rather an expen-
sive operation. With the pump, however. this
trouble will be done away with, and no fur
ther difficulty encountered in sinking. The
large body Of ore at present being opened by
