Mining Intelligence.

Gold. has been found in Richland County, Ohio,
and a company has been organised to prosecute the
discovery. From a few pans of surface soil $l2
worth of gold was procured.
Gold, silver, and lead have been discovered in
Lisbon, New Hampshire, and a company of Hart-
ford and Springfield capitalists have leased 600
acres of land for 100 years. Quartz taken from
this property has been analysed, and found to
yield per ton $867 in gold, and $l5O in silver.
The antimony mine near St. George's Lake,
on the Nlagagnadavic river, New Brunswick, is to
be worked this summer. A quantity of the ore
has been sent to New York and smelted, and is
pronounced superior to any yet discovered in any
part of the world, except that in France, and
equally as good as that. The mine is said to be
very extensive, and the gentleman who assayed
some of the ore says it is of great value.

The extent and value of the metalliferous deposits
of the Portage Lake district have steadily increased
from a mere beginning, ten years since, to a promi-
nent place in the copper-producing districts of the
world. In 1855 the shipments of mineral from
these mines were about 350 tons, or less than 300
tons of ingots ; in 1865 the exports of ingot copper
were about 3,440 tons, and of mineral 300 tons,
equal to say 4,600 tons in an unsmelted state. The
market value of this copper, at the time it was sold,
may be safely set down at over $2,000.
The value of the product of the Minnesota Cop-
per Mining Company for 1865 was $132,146 75 ;
total expenditures, $329,337 87 ; present value of
the property at the mine, $339,617 56, or about
$l7 for each share of the stock. The surplus of
available assets are estimated at $82,717 05. The
M4nnesota has a paid-up capital of $366,000. Par
value of its shares $5O. This company has paid
out $1,760,000 in cash dividends. Its stock has
been selling this week at 11.
The Lake Superior mineral regions are supposed
to contain valuable deposits of lead, which are just
beginning to be developed. The Holyoke lead
mine is making a very satisfactory exhibit. Their
principal lode is 30 feet wide, and well charged
with mineral from foot to hanging wall, giving a
lack of about 5 feet. It is estimated that it will
yield half a ton of ore per cubic fathom, and that its
costin stopping will be aboutsl2 per fathom. Another
vein of silver lead has also been struck about 15
Teet north of the first mentioned, which is said to
be the biggest thing yet found in the Silver Lead
region. Its specimens are very rich, the ore
being of a much finer grain than any previously
taken out, and closely resembling the richest ores
found in Colorado.
UNITED STATES GOLD AND SILVER PRODUCTS.
—During the eighteen years that have elapsed since
the discovery of gold in California the mines of the
Pacific coast have added one thousand millions of
dollars to the world's stock of the precious metal.
Australia and other cotemporary sources have pro-
duced as much more. Although these figures are
very magnificent, they have a very unsatisfactory
aspect when placed by the side of the sum of the
liabilities, present and prospective, of the United
States. Mining is still the leading pursuit beyond
the Rocky Mountains. The receipts of uncoated
gold and silver at San Francisco last year amountcd
to forty-nine millions of dollars, against forty-eight
millions in 1864, forty-four millions in 1863, forty-
two millions in 1862, and forty millions in 1861.
The area of the metalliferous region is steadily ex-
tending, and the miner contemplates with satisfac-
tion the fact that neither rain nor drouth, financial
panics, nor periods of great inflation, need seriously
affect his field of operations; The silver yield of
Nevada amounted last year to sixteen millions of
dollars, and the entire product since the opening of

her mines in 1859 has been forty millions of dollars.
This State has now in operation one hundred and
fifty mills, costing about ten millions of dollars,
with a capacity of two thousand stamps. The ave-
rage cost of these mills is seventy thousand dollars.
