which, on examination, was found to have been
scaled Off by the force of the blast from large
vein OF the same character, running nearly north
and south across the bot, ON of the shaft, which
had been carried to the depth Of fifty feet. The
appearance of this quartz was very similar to
that found in the mining districts to contain
gold, and Capt. Lambert was led to examine it
more infinitely, and breaking another piece from
the vein, weighing about three pounds, with the
aid of magnifying glass discovered countless
number Of minute glistening particles Of gold,
over the surf, ce of the piece of rock. On
further examination small vein Of clay and
black cinder-like decomposed rock was found
traversing the entire length about two inches
in width, on the east side of the main lead Of
quartz Capt. Lambert then communicated the
discovery to one Of The firm Of Mofflt g. Co.,
assayers and coiners of this city, and gave him
piece of the quartz, weighing about one pound
to determine its value. Mr. Motfat has not yet
returned report of the amount Of gold found
in the piece submitted to him, but wearainfefmed
on aoo.l authority that it proved llpeientlvrieh

easterly direction towards Clark's point. If
this lead ba found to extend further with equal
richness, Telegraph hill and the windmill will

From the Alta California, Oct. 2. r..
There seems to be but little doubt as to the
existence of valuable silver mines in California
We have from time to time heard OF discoveries
in various parts of the southern country but
the following account, which we take from =
somewhat lengthy article in the Stockton Repub-
ican, is sufficient to settle the question: "Eary
in the present year the exploring expedition left
Steckton, and, we believe resulted in nothing
tangible; although II. w. Wallis, eco, of this
city, showed us specimens from'thc region of the
Four Creeks, where deposits were found in in
calculabe amounts. Indeed this is the form i'll
which, it appears to us, silver is most frequently
found in California. II is kind Of black sui
phuret of silver, is blacklist, brittle, cellular
affording globules of silver at the bowpipe. The
Spaniards call il negrillo and il is also found
in large masses in Peru and Mexico. The speci-
mems we have seen have been of different de-
grees of richness, the amount Of silver varying
from 10 to so in 100, in various specimens. The
specimens brought down by Mr.. Wallis were
analysed by Moffat g. Co, with the following
result:
Silver, Gina ton weight of the ore). s2O6 40
Gold, 81 80
Lead, 1000 lbs.
Some four weeks ago, Mr.. Z. ID. Glboes, who
has been surveying in the neighborhood Of
Mount Diable, informs US that he had discovered
traces of silver in that ncighborhood, though in
whal form we could not ascertain. We believe
that that gentleman is at the present time absent
on the inquiry. The discovery which has called
forth these remarks, is one which has been made
by Mr. Joshua Holden, of Sonora. The follow
ing is the communication We have received on
The subject 1t is authentic, and may, We believe
be relied upon:
SONORA, Sept %. 1851.
"Mr Holden has discovered a very extensive
silver mine, which prospects fftycents per pound
silver, and fifteen cents per pound gold, with
other associated metals. If the mine proves as
rich as the prospect, il will be worth all the gold
mines in the southern district.
Tomorrow, Mr.. II. and party will start ont
for the purpose Of commencing regular mining
operations have seen a piece Of the ore,
which is the richest ever saw"
