The Nettie Mine.

The Nettie Mine.
Owned by Messrs. Roudebush & Young, is
situated east of and adjoining the Burlington.
The ledge here is very strong, showing heavy
groupings the whole length of the location.
The main shaft is down 80 feet in the ledge
carrying a fine body of ore to the bottom,
which is at present all in ore, about two feet
OF which, however, is manganese.
On the 45-foot level the east Drift is in so
feet the ledge here varying in width 8 to 7
feet in the face it is about 3 feet wide.
The west drift is in so feet running through
an ore body the average width of which is
about 8 feet, a streak that wide showing in
the face. w
On the S0-foot level a drift has been run
east 30 feet, showing a body of high grade
free ore (this ore, Mr.. Young tells me, aver
aged so ounces in the mill) about four feet
wide in this drift there is also a streak of
manganese which will go 60 or. It is shipped
to the smelter for reduction.
One thousand feet west of the main shaft
there is another shaft dewn 100 feet. The
east drift, 60-toot level, is in 123 feet. The
ledge here is wide, being about 8 feet between
the walls. 1t shows a streak of flee ore 3
feet wide and a large quantity of manganese
most of which, 1 understand, is low grade.
On the 160-foot level the east drift is in 20 |
feet showing considerable 80 or. manganese |
ore.
The west drift is IN IA feet, the face looking
we'll. On this level the ore is all base; they
are raising about 5 tons of ore daily. At
the
FredOnia Mine,
Situated south of the Burlington, the ledge
crops strongly. There is a shaft down 40
feet. The ledge in the shaft is from 7 to s
feet wide, carrying considerable free ore on
the hanging wall and a body of manganese
OF the foot wall.
A drift has been run 80 feet west from the
bottom which shows about 6 feet of vein
matter with considerable ore intermixed. At
the
Burlington Mine,
Owned by Messrs. Roudebush g. Young, the
shaft is down $50 feet in the ledge. In the
bottom the ledge looks very well, but it is too
base to be worked by the milling process,
consequently sinking has been suspended tor
the present.
On the 30-foot level the east drift is in so
feet the ore body in this drift is very wide,
averaging in the neighborhood of 7 feet the
face of the drift shows about 4 feet of ore.
The west drift, 3O-foot level, is in so feet
the ledge here is not so wide, 4 feet being
about the average. A streak about that wide
shows in the face. The rock here is very
hard.
On the 7O-foot level the east drift is in 30
feet, showing about p feet of free milling,
and considerable manganese ore. Tn body
of free ore narrows considerably on this level
and there is a much larger. quantity of man
ganese ore showing than on the 30-foot level.
The west drift is in about so feet, showing
about the same quantity of free ore as the
east drift, two feet wide in the face.
Above the 10 foot level the ore has been
pretty well stopped out. Mr.. Young tells me
that the ore from these slopes averaged 60 OF.
An idea of the quantity Of ore they yielded
may be formed, as the Burlington mill, with
a capacity of twelve tons daily, was kept rum
ming for one year on ore from the Burlington.
At the
Davy Mine,
Owned by Messrs. Mayer & Rowan, and stu
ated directly east of the Colusa, they started
work last week, and now have a shaft down
Is feet, the bottom of whichs shows considera-
BILE copper ore.
They will continue to sink as rapidly as
possible, expecting to strike some of the bod
les of copper ore which the Colusa mine has
demonstrated are plentiful in that section of
the country. At the
Alice Mine.
Explorations on the 5OO-foot level are still
suspended. They are working four pumps,
two on the 300-foot level and two on the 500
foot level. The leakage in the large pumps
was caused by a defective casting in the water
chest the work being done too hastily.
Mr.. DAILY is entitled to great credit for the
rapidity with which he got the small pumps
running. Five hundred feet of column and
all of the connections necessary were put in
in "a hours.
They are raising about the usual quantity
or ore. The slopes on the upper level are do
ing finely.
The stope ON the 4O0-foot level, where the
connection was made with the center winze
with the 300-foot level, is looking particularly
we'll.
1t will probably be from three to four weeks
before it will be possible to resume work on
the 500 foot level. At the
Gasnon Mine.
The new gallows frame is not YET completed,
consequently the hoisting engine has not
started up.
Sinking the main shaft will probably be re-
sumed as soon as the hosting engine goes to
work.
The west drift, 15O-foot level continues to
look finely, the whole face being in base ore
of a high grade.
About the usual quantity of free milling ore
is being extracted from the slopes near the
surface, and the 150-foot level is yielding a
large quantity of very high-grade base ore.
At the
National Mine
They are still sinking the shaft and prospect
ing the west drift l65-toot level, thoroughly.
There is little or no free milling ore left in
} sight in this mine. TIL ore at present being
extracted is all base. At the
Cora Mine
