The weekly miner. [volume] (Butte, Mont.) 1878-1881, 1880-01-06

from wall to wall nearly ~ feet OF ore n
vein matter, carrying two chutes of ore, one
about the center Of the ledge and the other
on the foot wall, from 5 to 10 feet wide. The
ore from this mine has kept the Centennial
mill running for several months, and al
though working a small force of men the
yield has been from 8 to - tons daily.
West of the Burnett lies the Buffalo, upon
which a shaft has been sunk to a depth of
about 60 feet. Until within the last few
weeks the ore in this mine was of too low a
grade to pay, then a streaklof rich ore was en-
countered and at present the prospect is very
f1attering.
The Mountain lode is next reached. The
eastern claim on this lode, upon which any
mentionable prospecting has been done is
the Mountain mine. The shaft has attained
a deplh Of about 12O feet, showing a very
heavy body Of high grade copper ore, in
places as wide as 8 feet drifts have been run
east and west from the shaft, which show the
ore body to be uniform in width and rich
ness. The west drift from the shaft on the
7O-foot level connect with an old shaft about
$50 feet to the west. From this level to the
surface the ore has mostly been stopped out.
They have a tine-looking stope of ore in the
east drift 9O-foot level, and the drifts east and
west from the bottom of the shaft show
ore in the neighborhDod Of feet wide;
this yields about II tons of copper ore daily,

ductiOn.
West of the Mountain there are several
mines upon which more or less prospecting
has been lone above the water level, upon
reaching which, :,cwever, work has in every
instance been stopped and the ore developed,
stopped out.
The leila and Pacific which lie on the
western end OF the lode both show fair indi-
cations on the surface, but the work so far
lone is certainly insufficient to determine
their value.
Lying north of the Mountain is the La
Plata lode, which has also proved very pro-
ductive in the past.
The Gray Rock, which is about as far east
as this lode has been prospected, has yielded a
large quantity of high grade ore. 1t Is pros
pected through two shafts; the main shaft,
where most of the work is at present being
done is down about 100 feet. From the bot
tom a cross cut south from the shaft, after be-
ing run about 40 feet encountered a very fine
body of free-milling ore from 3 to S feet in
width. Drifts are being run east an west,
and considerable good ore extracted from
! this section of the mine. Another shaft down
about 45 feet, lies abont $50 feet west Of the
main shaft from the bottom of this shaft
drifts have been run east and west, the east
drift making connection with the main shaft ;
from here, also, a very large amount of rich
ore mas D6en LukeH, dllu tllc leuSc lOOhS SCTOuS
and we'll defined.
Southeast of the Gray Rock lies the High
Ore mine, whether on the same ledge or not
it is impossible to say. The main shaft on
this mine, has been sunk to a depth of 100
feet without experiencing much trouble from
water. Seventy-fve feet from the surface,
drifts have been run east and west in the
east drift 80 feet from the shat: a Wine is
sum 30 feet.
Here a stope wasstalted, and an enormously
large lode, in places 16 feet in width of ore
developed; it is mostly of a rather low grade,
not averaging over 20 ounces to the ton.
There is, however, a chute of ore in the
ledge at his point about 6 feet in width
which will run a great deal higher; 300 feet
further east another shaft is down On the
ledge 80 feet; here it has narrowed to be-
tween ) and 4 feet in width. Although
the ore is of a somewhat higher grade than
that found in the drifts from the main shaft,
no work is being dom at this point at present.
The ore body in this mine is certainly very
large and can be cheaply worked; three men
having at one time broken as much as 20 tons
of ore daily; it is also of a very free character,
and the cost Of milling should not exceed So
per ton ; worked on a large sclale it would
probably yield a handsome profit.
The Belle mine, adjoining the Gray Rock
OH the east has proven to be a very productive
piece of property. Work was started on il
less than three months ago, and it has kept
the Clipper mill running ever since. The
main shaft has attained a depth of 70 feet
south of the shaft a very fine body of higI
grade copper and silver ore was struck and
drifts started east and west on it. The water
becoming very troublesome and there being
no present sale for copper ore in the cam
work was suspended at this point. Shaft No
2, about 800 feet east of the main shaft, il
being mi in a goOd-looking body of higl
grade copper ore drifts east and west from
this shaft have just been started at the pOin'
where the base and free ore meets; assay.
from here show 100 ounces in silver for the
free and 101 ounces in silver and 81 per cent
copper for the base. Shaft No. 5 is dow
about So feet there is a large stope in thu
east drift from the bottom from which abou
s tons of fine ore daily are being extracted
West OF the Grey Rock lies the Flag mine
and although comparatively little work ha
been done on this portion of the ledge, TIN
milling ore of exceedingly high grade.
West Of the Flag lies the Midnight, upo,
which little prospecting has been done.
Then comes the La Plate, a mine which i
said to have yielded more high grade or
above the water level than any other il
l camp. Never having seen this mine l ca,
: say nothing as to the width of ledge, nor q
the amount OF prospecting winch has bee
8 done in it.
, Next to the LaPlatte lies the Buenos Ayres
upon which considerable surface work ha
a been done, and very good ore taken out.
t North Of the LaPlatte is the Lexingto
lode, which has also proved wonderfully pre-
i ductive. The two principal mines on thu
lode are the Josephine and the Lexington
The latter has four shafts: one is down 8
s feet, the second, 200 feet west Of the first,
$ down 10 feet; the third shaft is down 6
n feet, and the fourth, in which little has bee
u done, has only reached a depth of 20 fee
n shafts have been run connecting all of thes
shafts. exceDtinp No, 4. and the ore body
