MINING INTELLIGENCE.

(Extracts from the San Francisco Mining and Scienti Rc Press.)
There is 1.30 Ar a great excitement on the Oro Fino
Mountain, Idaho, caused by the discovery of a rich
ledge, claimed by three different parties under as
many different names. The ledge bears evidence of
being immensely rich—from $5 to $2O to the pan
being frequently obtained from dirt and decomposed
quartz in the immediate vicinity of the ledge. We
saw ore that was taken from the vein near the sur-
face where Fogus is sinking a shaft with fine gold
visible to the naked eye all over it. The Minear
mill is now engaged in crushing the ore from the Ida
Elmore.

REVEILE, REESE RIVER, NEVADA, Sept. 16th.—
The Ophir mine in Manhattan district shows con-
siderable mineral, as far as explored, and several
strata occur in thebody of the vein, which carry very
fine ore. Towards the foothills, which jut into
Smoky Valley, is a hudge ledge, called the M'Mur-
ray, which crops out boldly. The one procured
from the surface, as well as from the deepest exca -
vations, assays largely both in gold and silver.
Besides these ledges there are several others which
appear to be highly metalliferous. Some 4,200 ozs.
of crude bullion were brought in from Cortez by
Rassell's stage on Saturday evening, and delivered
at the assay office of the Keystone mill for melting
and assay. It was produced from ore obtained
from the St. Louis mine. Some 3,000 ozs. of crude
bullion arrived this morning on the, tage. It came
from the mill of the Social and Steptoe Company
at Egan Canon. By the Austin stage yesterday
two bars of bullion were brought from the mill of
the Belmont Company.
Sept. 21st.—The Old Dominion mine in the dis-
trict of Hot Creek is producing ore of the finest
quality. Perhaps the best samples of horn silver
which hare yet been procured in any of the districts
south-east of Austin are now produced by that mine.
We were shown yesterday a massive piece of the
beautiful ore, which one could indent easily with
the finger nail. A person who saw the mine a few
days ago says that great quantities of this pure
chloride were being developed and extracted, and it
was estimated that lots of it would yield in the mill
from $l,OOO to pp() per ton. Of the ores sent to
the Paris Exposition from Reese River, and assayed
in the School of Mines in Paris, the greatest yield
was from ore from the Timokc mine on Lauder
Hill. The assay exceeded $6,000 per ton.
ENTERPRISE, Sept. 18. —A boiler, weighing,
9,0001b5, passed through this city yesterday morn-
ing for the Empire State mill.
Sept. 20th.—The Sierra Nevada Company are
steadily drifting for their lead, having cleared the
old tunnels of the mud which had accumulated in
them during the time the mine was flooded. The
mine is kept drained by working the pump one
hour per day.

Sept. 21st.—Steele and Co. are still engaged in
extracting ore fom the Sacramento mine, Cedar
Hill. They have but a small force of men at work,
but are making very good wages. Parties are
now engaged in getting out ore in the old Chol-
Jar croppings. We understand that they will
take out one hundred tons as a test crushing.
The total amount of *bullion shipped during the
past week from Wells, Fargo, and Company's
offices in this city and Gold Hill was 6,7391b5.,
valued at $143,519.67. The total number of ounces
received for assay during the week at the various
offices in this city and Gold Hill was 76,219.
Sept. 22d.—A force of men have commenced
work on the Coryell mine, situated just north of
the Overman works. The shaft, which is 185 ft. in
depth, has been thoroughly retimbered where tim-
bers were required, and a draft for the old Mary
Ann chimney is now being rapidly pushed ahead.
The Eclipse Mill at Gold Hill has resumed crushing
ore from the mine of the company. A reserve of
over 1,000 tons has accumulated.
PLACER COUNT; CALIFORNIA.— The Lincoln
correspondent of the San Francisco Bulletin writes,
Sept. 23 :—" The Valley View quartz is regarded by
all as very valuable. A mill of forty stamps has
been paying dividends on it right along. It is now
sold to an English company in London. Crosby
and Manter have a mill adjoining the large one
which works five stamps and two arastras. It is sur-
mised by those that know that the rock of the small
mill is by odds the richest. Nickerson, Cadwalader,
and Hubbard have nearly completed a third mill in
the same locality, of twenty-four stamps."
A correspondent of the Wall-street Journal, dat-
ing from Austin, Nevada, writes as follows :—" On
Lander Hill the mines that are being developed are
actually proving far better than was expected by
their owners. The Great Eastern, Savage, Oregon
(of the Manhattan Company), Magnolia, Florida,
Chicago (of the Midas Company), Kailseed (of the
Plymouth Company), and others, are among the
best paying. Only a short time is necessary to
make these mines of Lander Hill establish a credit
for the entire of Central Nevada. All the mines at
present under development in Nevada are proving a
grand success, and in May, 1868, accurate calcula-
tions are being made that the railroad will safely
land passengers within sixty miles of Austin City.
The Gold Hill News gives the mode of working
the ores of the Montezuma mine, in Arabia District,
Humboldt county, Nevada, as follows : —The ore of
this ledge consists of an oxide of lead and antimony,
and much of it combines in the form of an antimo-
niate of lead. The ore contains from $5O to $3OO
of silver per ton, and the entire vein of from 15 to
25 feet in thickness, is about 50 per cent., or one-
half metal. It is reduced by smelting. The reduction
works at first erected, though incomplete, produced
from 300 tons of ore $25,000 in fine bullion. The
