THE MINES.

sumcd on this very promising copper mine.
1t lies directly north of the Colusa. The
shaft is down 81 feet. Yesterday a crosscut
was started from the bottom to tap the ledge
which was struck within two feet. The ore
is OF improved quality and will assay proba-
bly, Az per cent. copper. The ledge at this
depth is known to be wide, but whether the
space between the walls is all filled with pay
ore is yet to be demonstrated. In appearance
the ore is somewhat similar to that produced
from the Mountain, being gray and soft.
MODOC.
This mine, owned by Ransom, Rosenthal
ct al, and located directly west of the Bell,
has been leased to Mr.. VIM. McDermott, who
has made a very good showing. The ore is
free milling in character, and tne ledge is
about four feet wide, showing a slight III
crease in width in the bottom of the shaft,
which is down about so feet. Assays have
been made varying from % to 1862 ounces, but
samples from one wall 70 the other show the
average value Of the ore to be $50. If the
character of the ore remains unchanged to a
depth of so feet drifts will be run and the
Clipper mill started into operation. Whether
the Modoc is an extension Of the Bell is not
known, but If present indications are realized
it will make little difference to the owners
whether it is or not. The dump is already
assuming gratifying proportions.
DIAMOND.
About DO tons of ore are on the dump. The
shaft is AZ feet deep, and the ore, which here
tofore has been low grade, is perceptibly i'm
proving in quality. The porphvry punches
previously encountered in the ledge are met
with no more, and the ore is considerably
softer than formerly, SO that good progress in
sinking may be hereafter expected. The 40
tons of ore Oh the dump have been extracted
and holsted by only three men within the
past week. The water level on the Diamond
is fully 1870 feet deep, if the theory is correct
that the mine is an extension Of the High
Ore, Of which there is little doubt. 1t is safe
to assert, therefore, when it is taken into COLI
sideration that the shaft has been all in ore
from the surface, that a vast amount of pay
rock will be extracted from the property be
fore the character of the ore changes to a
base. q
BELL.
The east and west drifts from the bottom
of the middle shaft are all in ore OF
excellent grade, and shipments East are be-
} ing made almost daily. The temporary de-
lay caused by bad air in the east shaft has
been tided over and the driving of the west
drift is actively progressing. Hosting
tbrr,,ub tIiS Shaft is bniun lpna hv q whiO1
and day aud night shifts are employed.
LEXINGTON.
No important developments have beer
made in this property during the past week
The main level, which runs east and west al
an average depth of SO feet from the surface
2 continues to yield a sufficient amount of ore
, to supply the Lexington mill. Several. thou
/ sand tons of free milling ore are yet in sigh
in the drifts and slopes of the mine, so tina
, its productive capacity will not be tested un
S til additional milling facilities are provided
! Sinking on the big shaft is going ahead salts
-. factorily.
TAR WEST.
e The main shaft has now attained a deptl
of 100 feet, which is somewhat remarkable
= from the fact that water was first encountered
: only 20 feet below the surface, and that every
thing has been hoisted with windlass o
4 whiln. The ore in the bottom is a little owe
= three feet wide, hard and rich, assaylns be
tween $500 and $500 per ton. The rock is o
a light color, and carries a mail. f%ercenlag
Of iron. From the slopes in the workings o
the middle shaft some excellent looking or
{ is being produced, which will assay from ST.
10 5000 per ton. The Slope from the cas-
level within the past few days has beeI
a pushed to the surface, pay ore being found t
e the grass roots. 1t is the intention of tn
T. owners, at an early day, to import and plac
in operation some heavy sinking machiner
6 and put down 4 shaft 500 leet deep. Whej
5 the present main Shaft was started, the eXCep
Il tional richness Of the ledge at any considers
BILE distance below water was scarcely eS
pectcd, or at least The owners were not suti
GENTLY confident of It's permanence to sink
Shaft anywhere but OIL the vein, where the
could 1ote its changes. This shaft was {
course an incline, which could not be worke
to advantage with an engine; but SO niue
and so rapid, has the ledge continued t
4 improve III richness and indications Of pei
6 maneuce, that no further apprehension is teI
for the future of the property, and within
d few months at most We may expect to hav
@ another big shaft started, to add to the nun
II Der Of those already under Roadway on othe
mines.
