ounces.
The State of Nevada is likely to produce somewhat more silver in 1908
than in 1907. A difference exists here, too, in the figures of the mint
report and of the mines report. The former gives for 1907, 8,280,500
ounces of silver for Nevada, while the mines report only has 7,083,603
ounces, an excess of the mint report of approximately 1,200,000
ounces. This is probably accounted for by the fact that many smelters
were well stocked with Nevada ores at the end of 1907 and kept running
for a considerable time after the mines had been temporarily closed.
New Mexico.—The
gold produced by the New Mexico mines was valued at $329,982, an
increase of $36,963. Grant County led as usual, owing to the gold
produced at the mines of Pinos Altos, but the county is now closely
followed by Socorro, the mines in the Mogollon having largely increased
their yield. No other county reached a production of $100,000, Lincoln
County reporting the highest production, $41,417. The total placer
production was only about $20,000. Most of this came from Colfax
County, the production of which has, however, greatly decreased in the
last few years. The siliceous ores yielded about $240,000, the copper
ores approximately $46,000.
The
production of silver amounted to 705,544 fine ounces, an in- ' crease
of 214,417 ounces. The leading counties were Socorro, Grant, and Dona
Ana. The mines of the Mogollon district nearly doubled their
production. The greatly increased production of copper had little
influence on the yield of silver. From siliceous ores 542,252 ounces
were obtained, chiefly from Socorro and Grant counties. From the
production of copper ores 115,323 ounces were obtained, to which Grant,
Santa Fe, and Socorro contributed the largest portion.
New Hampshire.—A small production of silver was reported from lead ores mined .in New Hampshire.
Oregon.—The
production of gold in Oregon amounted to $1,129,261, a decrease of
$237,639. Of this amount $396,478 came from southwestern Oregon, and
$732,783 from the districts in the northeastern part of the State. The
total yield of the placers was $331,406. To this amount the
southwestern placers contributed $239,942 and those of the northeastern
district $91,464. Compared with the production of 1906 the
southwestern placers showed a decrease of over one-third, while the
placer production in the northeast nearly doubled. Baker County was the
largest producer of gold from siliceous ores; Josephine County had the
largest output of placer gold.
The
yield of silver was small in 1907, as usual, and amounted to 86,718
fine ounces. To this Baker County contributed 69,589 ounces.
South Dakota.—The
mines of the Black Hills decreased their output by $2,703,280, the
amount produced being $4,138,189. The year was an unfortunate one for
the mining interests owing to a disastrous mine fire at the Homestake
property and to strikes at other mines in the beginning of 1907. The
larger part of the decrease was due to the interruption of work at the
Homestake mine. No smelter was in operation in the Black Hills in 1907.
The 350-ton cyanide plant of the Mogul mine was remodeled. A large
increase in production is probable for 1908.
The total production of silver was 93,895 fine ounces.
