The number of veins Of mineral bearing
rock around Butte is really something to
wonder at. In an experience extending over
several years, during which time 1 have visi-
ted nearly every camp of note west of the
Rocky Mountains, l have seen nothing to
compare with it, excepting, possibly, White
Pine, where, although the ore was largely
difused over the surface, from all hour
TO a weeks work inevitably takes you to tie
end CT the ore body. There, too, the country
rock is limestone-a formation, which, as a
rule, is unreliable.
THE GAGNON NINE
Property of Messrs. Rosenthal, Thornton Il
Co. is worked through two shafts, The main
shaft is sunk in the toot-wall and has attained
a depth OF TO feet.
On the so foot level a drift has been run
west $50 feet. Here, there is a Slope about 100
feet long and varying in width from 10 to IA
feet; it will probably average II feet. The
face Of the drift is mostly vein matter, with
streaks Of ore running through it, which
looks favorable. The 50 foot level east is in
about 70 feet, extending to the line of the
Original NINE; here the ore body is narrow
er, the stope opened on this level not being
more than from three to four feet wide.
At the 50 foot level water was struck, and
the character of the ore changed from free
milling to base, all of the ore extracted from
below this level being of the latter character.
On the 100 foot level the west drift from the
shaft is in about 250 feet. The streak'o of pay
ore in the face of this drift is about two feet
wide; a large stope has been opened here, be-
ing in places as wide as eight feet-it will
probably average four feet its whole length.
The ore goes from 60 to 100 ounces in silver
and from Is to 40 per cent. in copper.
The drift east III this level is in Is feet.
The ore body here will average about the
same width (four feet) as in the east drift of
the so foot level, although The ore is entirely
different i'll character, having changed from
free milling; on the so foot level, to copper
ore at this point.
Lying south Of the 100 foot level, and run
ming parallel with it, is a very large body of
low grade, base ore; it has been crosscut in
but one place, where it is 20 feet wide; this
ore body carries from Is to 20 ounces in sill
uel, and some copper; it is, as yet, undevel-
oped, the 20 foot %crosscut, mentioned above.
having begun and ended the prospecting lone
on what will probably, in the future, turn out
to be a remarkably fine chute of ore.
The west drift, $50 foot level, is in 1862 feet,
the face showing about 20 inches of rich ore.
AhAS "oNy ~ H"J "a AZ I4hO IL i u " tVO
to five feet wide, and is identical III character
with the ore found on the 100 foot level and
will average 20 per cent. in copper.
In the east drift $50 foot level the ore to-
day has pinched down to a width of about
two feet. 1t is, however, very rich in copper
and goes about ITO ounces in silver.
Shaft No. 2 is situated 50 feet west of the
main shaft it has been sunk to a depth of
100 feet. AT this point the west drift of the

About 10 tons of free milling ore are being
extracted daily from the workings above the
so foot level, and from Is to 20 tons of list
and I'd class base ore from the lower levels.
Until lately all of the base ore has been
shipped East. Now, however, it is mostly
worked at Clark's smeltcr.
The new hosting and pumping machinery
will be in running order about the first of
December, when sinking will be resumed and
prosecuted vigorously. A stationary Knowles
pump will raise the water from the $50 foot
level, and a No. 4 Dixon will raise it to that
point.
The capacity of the mill is increased from
five to ten stamps, which will increase the
output of the mine; it should, in fact, double
it.
The hosting is now done with a one horse

saw the size of the ore bodies on the so and
100 foot levels. Twenty-one men are now at
work at the mine.
THE JOSEPHINE
is owned by the Silver Bow Company and
lies directly east of the Lexington. The
main working Shaft is 107 feet deep, vertical.
Ninety feet from the surface a cross-cut runs
north about 1I5 feet and cuts a ledge of base
and free milling ore, mixed, about 7 feet
wide. This ore body has been prospscted by
a drift which extends about so feet east of the
cross-cut and 60 feet west. The drift carries
a..streak OF free milling ore, varying from , to
/ feet in width, its whole length. The ledge
seems to be widest where it was cross-cut.
The faces of both the east and west drifts
show a streak of ore about 3 feet wide. A
cross-cut was also run south from the shaft OH
the 9O-foot level. Fifty feet from the shaft
an ore body, about 6 feet wide was crossed
