TONOPAH Mine MANAGERS MAKE REPORT
ON DEVELOPMENT WORK FOR PAST WEEK

punches of very rich sulphides occur.
The crosscut then passed through al
ternate streaks of low-grade quartz
and West End rhyolite for about 6
feetn land then through about 8 feet
of ore averaging from $40 to $12 a
ton. At this point a horse of rhyo-
lite was encountered which in places
is split with quartz seams showing
very rich solid black sulphides, and
another oreshoot was then encoun-
tered on the hanging-wall side of the
vein. This is about 6 to Z feet wide,
of excellent mill ore, in which
streaks and punches of rich black
sulphides occur, as on the footwall
side. Drifting both east and west on
the footwall side of the vein is in
progress, and the length of the ore
shoot has now been proved for about
80 feet on its east and west course
and on the hanging-wall side for
about 80 feet on it's eastern course
and drifting west on this will be
commenced very shortly.
On the footwall side of the vein an
east drift has been run under the
vein for a distance of about 100 feet,
and from this two raises are being
put up to the vein, and one of these
will be continued up to the S50-foot
level to prove the continuation of the
orebody to that height. This raise
has just encountered the vein in very
good ore.
TOnopah Mining Co.
The Last Chance vein in the To-
nopah Mining company's Red Plume
mine continues to develop in a most
satisfactory name and while it has
already yielded a large tonnage of
excellent grade ore promises to pro-
duce a very greatly increased ton
low those on which it is now being
stopped.
On both the 500 and 66O-foot
levels, it has been proved for a
length of 200 feet, as exposed in the
slopes, for a width of from 6 to s
feet and it is evident that it now ex-
tends up to the 500-foot level and
drifting to it has now been started at
this depth.
Below the 600-foou level the vein
has split into footwall and hanging
wall streaks. both now about 2 feet
wide of mill pre-, but it is probable
these will unite, in drifting, into one
orebody and also at the S00-foot
level where the west drift to pick
up the vein is in trachyte formation
showing punches of quartz.
There is therefore a strong prob
ability that the vein will be proved
from above the 400-foot level to be-
low the S00-foot level and as it dips
at an angle of about so d grees and
large tonnage of ore will be avail
able.
North Star
About the second week in January
the milling of ore at the MacNamara
mill, it being the intention to COM
mence with moderate shipments, and
gradually raise these to SO tons a
day, when the developed ore in the
mine justifies this condition. The
contract is made for one year, and
will prove advantageous to both COM
panies, inasmuch as the North Star
will effect a saving over the rates at
present paid on ore shipped to Mil
lers, and will also be enabled to treat
at the MacNamara mill a lower grade
ore than can be proftably sent to
the old Belmont mill.
The mine continues to open up in
a most satisfactory manner. On the
1O5O-foot level what has been iden-
tilted as the eastern extension of the
Montana-Tonopah G.. e. X. vein has
now been opened up. This vein is
located 100 feet north of the Mac
donald vein, and is from 2h to 5
feet wide, and was stopped up to the
North Star boundary line on the bot
tom level of the Montana mine.
Prospecting of this ore in the North
Star mine has opened up some very
fair grade mill ore in two places, and
at these points raises are being
started to prospect the vein on its
upward extension.
TOnOpah Merger
Drifting west IN the 1170-foot
level of the Tonopah Merger mine
is still in progress, the drift having
recently passed through a length of
about 40 feet of broken up quartz,
which is recognized as the same
break encountered in the western
workings of the Tonopah Extension
mine, having a north and south
course, and which in that mine
greatly disturbed the vein.
The face of the west drift in the
Merger mine now shows greatly i'm
proved conditions. The vein is of
