mine va one Of the early mining loca'
tons OF the country. and has been
worked upon and prosPsctsd from time
to time: yet. comparatively little in the
way Of a regular and effective system Of
practical working development has
been followed until the present
time. II is now owned by q
company OF San Francisco capita

Of the ledge N already shown By prsvi-
Gus workingz, are making u productive.

and milling the orc. The Supsrintsnd.

a visit Of inspection to the mino ycstsr-

explorations and observation:
The mine Is situated In the hills 10
the noIthward Of Silver City. and about
q mile distant from that place and Is
easily accessible by a good wagon road.

Of from 20 to % tons per day. Should
additional milling capacity be secured q
considerably increased quantity OF ore
could bs easily supplied from the mine.
which is already in pretty good work
ing shape and in getting more so
all the time. The ledge Is very
well defined at tho surface. and runs
across q steep hill in nearly q north and
south direction, and the old surface
workings along its line show II to pro-
serve n dip or inclination OF about 40
degrees. down to the level OF tho main
tunnel, the present lower working level.
which opens the ledge and mine 800 feet
below the surface. This main tunnel or
adit ommenees at an eligible point on
the north side Of n ravine. and In about
$50 feet in length. II intersocts tho
vein about 40 feet from its mouth and
follows il. The vein ia from five to ton
feet wide ON the average. although in
| places il il lG or 90 feet wide. The
hanging wall Is Of remarkable regularity.
smooth and well defined throughout, and
| the vein is Of a very advantageous width
for working. ore extraction. timbering.
etc.
Tho principal workings, in the way OF
| ore extraction nj present. are confined
to the northern portion Of the mine,
where, for o distance Of LIS feet. stopping
is being done at short intervals, above
the tunnel level. taking out tho ore.
Tho highest raise In the stopping Is to
tie height Of 80 feet above the tunnel
level. showing tina, there Is a very large
amount Of orc between the tunnel and
the surface. to say nothing Of what must

in driving the tunnel farther ahead. Tho
general character II tho ore Is n dark
yellowish or reddish brown quartz. some
Of which is hard. white and flinty, while
the riches, portion Is moro OF n elayey
or soft nature. interspened with streaks
o. soft black ore or clay. rich in gold. IL
is essentially a gold vein. tho proportion
% silver being one-iourth or fifth. Con-
siderable free gold. visible to tho naked
eye. is met with. tho silver existing in
the form OF chlorides and sulphurets.
Twenty men arc employed in stopping,
trmbling the orc through shutes and
otherwise down to the tunnel level,
