MINING INTELLIGENCE.

NEVADA.--The latest mining intelligence from
Nevada is of interest. The report of the Secretary
of the Gould and Curry mines shows the total receipts
of the company for the past year (1865) to have
been $2,519,095 55, of which $2,395,242 31 were
the receipts from the mine. $618,000 have been
paid out in dividends. Total expenses at the mine,
$609,135 97. Expenses of reduction works,
$356,865 81. Liabilities, $71,206 83. Assets,
$1,067,998 81. The assets include the buildings, ma-
chinery, materials, and ore unerashed. Ores extracted
—First class, 11 tons ; second class, 4701 tons ; third
class, 45,492 tons.
Cost of extracting ore from mines per ton slo 84
Cost of reducing third class ores at Gould and
Curry mill l4 46
Cost of reducing third class ore at custom mills
Cost of reducing second class ore at custom mills 50 00
Average yield of all ores reduced, per ton 5O 76
11 second class ore 255 66
71 third:class ore at Gould and Curry
71 mill 44 26
51 all ores reduced at custom mills 45 12
From the annual report of the Secretary of the
Empire Mill and Mining Co. we learn that during
the past year the receipts have been $543,081 79,
and disbursements $525,129 79, of which $120,000
have been paid in dividends to stockholders. The
report says :—At present our prospects for obtain-
ing a continuous supply of good ore from the mine
are very flattering. Our Superintendent estimates
the supply found in the 160 feet level before referred
to at from 10,000 to 12,000 tons, and in sight in
other parts of the mine sufficient to give our mills
about a year's supply.

The Twin River district, according to the Reese
Reveille, still attracts attention. Professor J. E.
Clayton, Mr. Clink—agent for parties in London—
Colonel Rust, and Mr. Herman Camp, of New
York, and other persons of note, have recently
visited and inspected the district with the view of
purchasing mining property.
COLORADO.—Some recent advices from this em
byro State with regard to the yield of the precious
metals from her abundant sulphurets surpass even
the auriferous tidings from Montana and Idaho.
We are assured that Mr. James E. Lyon, formerly
of Ogdensburg, New York, who has for some time
devoted his energy and capital to the application
and perfection of smelting processes hitherto un-
used, is already turning out $12,000 in bullion per
week, and expects soon to double this amount. At
this rate his outlay of some $150,000 will soon be
returned to him.

We have already explained that the sulphurets
which imprison the gold of Colorado are composed
of or contain iron pyrites, copper pyrites, galena,
zinc, sulphur, arsenic, antimony, &c., so obsti-
nately blended that they yield but a fraction of
their value to the simple calcining, crushing, wash-
ing, and amalgamating processes which answer a
tolerable purpose when the gold is " free." It is
confidently asserted that the difficulty has now been
surmounted, and that henceforth Colorado is to ad-
vance with great strides on the pathway that
leads through energy and thrift to prosperity and
wealth.

Another account from Colorado says--We have
one furnace of thirty-five tons capacity, and a small
furnace for prospecting with, of four tons capacity.
Business here is quite dull. Everybody is waiting

for the results of the different processes now berg
tested. We are quite sanguine of the success°
the Mason Process, and expect to send on satisfac'
tory results in a few days. There is quite a com-
petition between us and the Hagan party to see
who will get the results first ; we are now ready, to
give results whenever we get the order from MW
York.

MONTANA.—A local paper, reviewing the his'
tory of this important mining region, says';
Four years ago this entire region was uninhabited'
except by wild savages. In the fall of 1862
was first discovered in the Bannach District. 111
' 1865, according to the returns of the Intern'l
Revenue Bureau, the product of gold and silleri
was over $16,000,000 ; a result without a paralle
in the history of this country. The development
the coming season seems to promise great activith
and the production of both gold and silver Will be
largely increased over that of last year. Silver
mines have generally proved more profitable and
reliable than gold mines, and this territory seems to
possess more extensive silver veins than have bee;
found elsewhere, and the richest of these yet foenou
are in Beaverhead county. Several new minim
companies have lately been organised upon proper 4
in that county mainly for working the silver 100'
which promise great success.

KANSAS. - The " Yea Tar Spring," in Atliuni
county, discharges large quantities of petroleum
It has been known for more than alit!,
years Oil has been found in the 310'

wells at Ossawattomie and Paola. 'The Lykifis
well is reported flowing oil in considerable quail'
tities. The well is 275 feet deep. The workll
say that they " got oil all the way down." A
Louis Company have got a well 101 feet deep lie3'
by. Indications good.

lOWA. - Discoveries of petroleum have been
t
recently made in Alamakee county, lowa, abut
three miles from Hopkins Ferry, near the
Mississippi.

TENNESSEE.—An Exchange states that the Ten-
nessee Mining and Manufacturing CompanY
which General H. D. Whipple is President, an
u
General R. W. Johnson Secretary and Treasurer'
has struck oil on Flint River, three miles from it°
mouth and twelve miles from Decatur, Alabama'
The oil was found fifteen feet below the surface
and flows in a steady stream.
ENGLISH INVESTORS AND AMERICAN M114E5...:
The New York Mining
_lndex says :—We are ale
iowts
that many mine owners and proprietors of valuable
mines in our North-western country are nulL
England, endeavouring to negotiate with capitalist
and promoters for developing our valuable Oil'.
But we opine that their hopes may not be realise"
if we are to judge of the present state of affavirirs'
It is doubtful, too, whether any property of .7t
character has ever been presented in that mark
which could produce better results than the go:„:
silver, copper, and gold mines, and petroleum vre'e
which, though yet in their incipiency, ha vi
astonished the world for their metallic and mines
value.
