THE MINES.

Line.
NORTH STAR,

' hoo oeeh undef tease Tor several
months past to Mr.. O'Brien, who undertook
TO develop it soon after the previous ~lessees
haa thrown it up. The vertical shaft yester-
nay attained a depth of IS feet. In the upper
part OF the shaft the ledge appeared irregular
ana ioll Of worthless matter, but a steady i'm
p'oVeMent was noticeable with an increase of
depth, and at present in the bottom the foot
wall is we'll defined, and the ore is conlpact
clean and of improved quality. A stump is
now being excavated and drifts east and west
VIII be started within q few days, when we
may expect The productive capacity of the
mine to be largely increased. The dump
cohtal~s about so tons of fair grade free ore,
which will probably be worked at the Clipper
mill.
MAGMA HARTA
AT a depth of 2CG feet in the main shaft
drifts north and south have been started,
which have each attained a length of 25 feet.
so far no ore has been encountered. The
north crosscut is expected to tap the six-toot
ledge which was passed through in sinking
the shaft at a depth of about IS feet, and the
south crosscut will tap the main ledge. 1t is
possible that the two veins unite at a greater
depth, and that the shaft is being sunk in a
'horse' between the two, but if this should
not prove to be the case they will be followed
and separately developed.
Until the elbow tor the water column can
be cast, thus permitting the extension of the
7OO-foot crosscut, there will be nothing to
make known in relation to the mine which
has not already been published. On the 400
and 5OO-foot levels operations are principally
confined to the slopes, which are keeping the
old mill supplied and increasing the surplus
at the dump of the new mill, in the vicinity
of which nearly five thousand tons are now
piled. Considerable ore will soon be taken
from the upper levels, it having been decided
that if the roasting apparatus of the new mill
is not ready to start when the rest of the ma
chinery is in working order, operations will
begin on free ore and continue until the
rOasters can be fired up.
ANsELMo.
On the 70-foot level, at a point in the
west drift 100 feet from the main incline, a
new shaft is being raised to be used as a main
shaft. 1t is now within six feet of the sur
face, and will probably admit the daylight
before the end of the week. A whim, the
timbers for which are already on the ground,
will be at once erected and the shaft will be
continued downward from the 70-foot level
to as great a depth as can be attained without
steam hosting facilities. From the bottom
Of the Old incline the west drift is being ex-
peditiously pushed forward, and is now in
between 65 and 10 feet, following a 8 foot
vein of high grade base ore which lies clean
and compact between well defined walls,
The Anselmo is one of the many mines OF
this district which shows a rapid improve
mcnt with the attainment of depth, and it is
to be regretted that Mr.. LaCaf7s lease is not
long enough to warrant him in importing
steam hosting machinery so necessary fort IN
speedy development of the young bonanza.
ACQUISITION.
lAltIlOuSh Vic III Va "abSt ~ CI' wv
tom of the two working shafts prevents any
further sinking with the present facilities, it !:
encouraging to note that the owners of the
property are exerting themselves to give i
the benefit of a thorough development at the
earliest practicable moment. Yesterday pre-
parations were made to sink a new shaft abou
100 feet south of the old workings. Thi'
shaft, for the sinking of which the first ION
foot contract has already been let, will con
tain two compartments and will be sunk will
a within for the first 100 feet, after which
steam machinery will be put up for deepe
development and another compartment adde'
to the shaft. The ledge, it is expected, vii
be tapped at a depth of 25O feet. In tn
meantime, however, the other shafts will no
remain idle. AT a depth of s. feet, or abOu
20 feet from the bottom, the wv working
shafts, which are 10 feet apart, have beef
connected by a drift. which along its entir
length shows a vein of ore varying in widtl
from five to eight feet, and assaying from 6
TO 100 ounces per ton. This quality and thi
width of ore are known to extend half wa
from The level to the surface, and a force @
men is now engaged in stopping and hoistin
i, to The surface. One hundred tons of or
has been shipped to the smelter during tn
past ten days leaving between 100 and 50
tons on the dump.
BELL.
Sinking continues in the middle Or viii,
shaft, which yesterday attained a depth OF 10
feet. About two weeks ago it will be remem
bered, when the shaft was but 140 feet deer
a ~crosscut north was started from the bottom
striking the hanging wall at a distance of l
feet. Fourteen of this is feet across tn
ledge was found to be composed largely G
copper pyritcs, assaying about 80 per cent. {
