New Discoveries of Silver and Geld In the
Sierra Nevada.
The following is a condensed account from
a recent number of the San Francisco Alta
California, of rich veins of gold and silver
ore, lately discovered on the eastern slope of
the Sierra Nevada range:
Mines that bid fair TO equal, If not surpass,
any thing known in the history of Califor-
mia, are now being opened up in Mariposa
and Tulare Counties, in the south, eastern
section of the State. In the Coso District,
in the eastern portion of Tulare County, the
gold and silver-ores have assayed at the rate
of 81, 500 to $4,000 per tun, from pieces
Clipped off from the weather-worn outcrop-
pings with sledge- hammers, crowbars, &c.
But as if this were not enough to excite the
cupidity of lucre- loving humanity, a start
ling discovery of gold and silver bearing
antimonial ore has recently been made,
specimens of which have been assayed at
San Francisco, and yielded the astonishing
amount of more than SIC, 900 to the tun
This extraordinary " Lead is in the hands of
parties who, naturally enough, do not court
publicity in regard to the locality of their
splendid prize.
Besides these dazzling discoveries, the
Mono Lake district, which is located at the
junction of Calaveras, MaripOsa and Fresno
Counties, is known TO be a prolific field for
mining operations, both in silver aud gold
while il has been demonstrated that the vast
mountains of quartz which comprise the
greater portion of Mariposa County, known
for their prolific gold yield, are even richer
in silver. A rich vein of silver has been
traced across the north, eastern part of Mar
iposa County, on both sides of the mount.
ain range, which leads to the belief that il
is the initiative of q vast bed of silver ore on
the west side of the Sierra. In Calaveras
County numerous discoveries of extraordi-
nary richness has been made, and it is fur

as far east as the MohGye and Colorado
rivers, which promise to be of vast import

The silver lead in Mariposa County has a
somewhat romantic history, as told by the
AltG:
The silver lead, it is stated, was diseov-
cred in 1856, but the discoVereT was unaware
of its nature until last winter. In his wan
behring's about Mariposa, where he mined, he
at different times prospected, carefully mark
ing the rock he returned with. In 1856,
while hunting, he discovered what he
thought to be q lead mine. He pocketed
the prospect, but thought it o. no value in
comparison with gold. mo
In 1853 he went East and remained with
his relatives, taking with him his collection
OF minerals ana g0id specimens. Last
February be saw q specimen of Washoe ore
al W. T. Coleman & Co.'S, in Wall street
and remarking the resemblance to his lead
specimens, procured a piece to compare with
his own. He was so well satisfied that they
werei IDENTICAL in nature that be had each as
sayed, and his "lead specimen proved to be
rich silver ore. Keeping his " counsel,
he reformed to California last Spring, aud
has spent the intervening time in ~retracing
his footsteps over the chemical and chaparfal
hills Of MaFiposa, and his Investigations rave
resulted in his discovery as above named.
Mining and scientific parties are now en-
gagged in exploring these new mineral re-
giOns, and the stream of adventures il al,
