THE MINES.

Lexington md Bell.

Inc working and paying mines of the
'""P nave become so numerous within the
i1sI SIN months that it is impossible to en-
ooay them all in one report. Consequently,
"a Wiling up the various mines of the camp,
we are compelled TO take some at one time
ana some at another.
ANSELMO.
lhe main shaft is down 10 feet, showing
a three-foot ledge of very fine looking ore in
the bottom.
me 'o-foot level east is in Is feet, showing
ABOUT Is inches of ore III the face, West
lhey nave run 50 feet and have started a stope;
tLe ledge in the DRIFT is about two feet wide.
out IN the slopes it improves and is much
wider,
Inc west shaft is down IS feet, but the air
becoming bad and it being almost impossible
70 OBTAIN an air pipe, work has been suspend
{" until connection shall have been made
with the main shaft. The bottom of the
shalt shows about two feet of frst-class ore
IL Is probable that the connection will be
made this wec., as the 7O,foot level from the
main Shaft is only about 20 feet from the bot
tom of this shaft.
East OF the main shaft IA shaft has been
started which is now down about 10 feet
the ledge in the bottom looks well.
The ore extracted from this mine is mar
Vellously rich, showing native and wire silver
in a way that would make the average pros
pector's eyes water.
The ore at present extracted is being taken
to the smelter.
MOUNTAIN BOY.
lhe work OF prospecting has been resumed
III a manner that shows that the owners have
every confidence in the mine. Work was
suspended last fall on account of water. but
the prospect in the bottom of the shaft was
so encouraging that it was decided to pur-
chase machinery and proceed with the pros-
pectlnS. The machinery consists of a 20
horse power engin and a No. 7 Vertical
Knowles pump, which will throw y 1000 gal
Ions of water per hour.
On the 100 foot level drifts have been run
east and west as follows: East IS feet, show
ing ali ore body from one to four feet wide,
with a streak of ore Is inches wide in the
face. Near this point a porphyry dyke was
encountered, which cut the ore out, and con-
scquently prospecting on this drift was sus-
pended. West, they have run 1875 feet, the
ledge showing the same width and general
characteristics as in the drift east. From the
1OO-foot leyel to the surface the ore has all
been stopped out.
The shaft is now down III feet, and the
bottom shows a strong and well defined ledge
three feet in width. As soon as the Shaft has
been we'll timbered sinking will be resumed
with energy, and the Mountain Boy will rank
among the first-class mines of the camp.
GREY ROCK.
The new working shaft is now down IS
feet. 1t was started about 10 feet south of
the ledge, and as water has not yet been ell
countercd, it is still being sunk by windlass.
by January his shaft will have attained a
depth of 800 feet.
Thu 90,fooL level east is HOW in 125 feet,
showing an ore body in the face from three
to five feet wide. Where the ledge was cross
cut on this level, at the shaft, it was nearly
20 feet in width. and varies from that to three
feet (ts narrowost point) its whole length.
The slopes on this level are at present yield
ing 10 tons of ore daily this will give some
idea of the magnitude of the ore body.
There is a large quantity probably 1000
tons-of roasting ore at present on the dump,
which has been extracted from the various
workings of the mines and which only awaits
the completion of the ~roaaters, now in pro-
cess Of erection at the Silver Bow mill, for
reduction. 1t is estimated that there is sufli-
cient ore now on the dump to keep the mill
GEO stamps running for three months. BY
shat time machinery will have been erected
on the new shaft and most of the ore will be
raised through it.
The new three-compartment working Shaft
is down so feet. This shaft was started about
100 feet south of the groupings, and it is ex-
the surface. The ne" hosting ANA pumping
machinery Is now Ell route and will arrive
soon. The frame for the shaft house, the di-
mansions Of which are 7OxlU0 feet, is about
ready for raising, and ere long there will be
another set Of hoisting and pumping works
in the camp which will bear favorable COM
parison with any in tie country.
The old workings continue their daily ont
put Of about - tons of ore, which is sutli-
cient to keep the Lexington mill running full
blast.
BELL. +
During The last week a tine body Of high
grade ore was encountered on the south wall
in the middle shaft, which is now dow $50
