A RICH STRIKE.
Discovery Of a silver Ledge Near
mOnFOVaR.

M OnrOv10s
A discovery of silver ledge has been
made in this vicinity, which is consid-
cred to be exceedingly rich by the dis
coverer, Gus A. Carson. Mr.. Carson has
been a mining prospector for the past
twenty-five years, in Nevada, Montana,
Idaho, Colorado, Arizona and California,
and has either worked in or examined all
the leading mines of theue States, and he
feels confident he has now struck some
thing that will surpass many of the best
mines he has seen. He has been pros
pecting in this section for the past six
months, principally in the Bliss and
Bradbury cafions, Just north OF Duarte,
and about mile and half northeast of
Monrovia.
Hearing that Mr.. Carson had opened
up a good ledge, a Messenger representa-.
tive visited his camp on Tuesday after
noon, for the purpose of seeing some of
the ore, and if possible to examine the
location. He readily escorted us to the
claim, which is in section 10, in the right
hand fork of what is commonly known
as the Wright csfion, and about three
quarters of mile northeast OF the Bliss
brothere' house.
The cafion is quite easy of access by
foot, and with the expenditure of few
dollars could be made good for wagons.
In very few minutes we arrived at the
location, and were shown a large hole in
the side of the ravine, where the vein
had been cross-cut. Mr.. Carson says he
was first led to the discovery by the con-
centration Of the float, and one day re-
Gently ran onto the groupings of the
vein, which shows itself on the north
wall of the ravine in thu shape of rain
bow. (Mr. Carson has named his claim
"The Rainbow.") Several places in the
immediate neighborhood show signs of
the picks of previous prospectors, but
they have evidently been men not famil-
lar with this class of ore, or they must
have discovered this claim many years
ago.
The ledge runs in a northwesterly and
southeasterly direction, with a dip
towards the northwest. At the apex the
ledge exposes to view width of ten feet
from the foot to the hanging wall. The
hanging wall is composed of porphvry
and the foot wall Of granite rock. The
and porphyry. The geological charsc-
teristics Of the surrounding country rock
|is various composition of
granite, porphyry and trschite. The
character Of the ore, as far as has been
exposed by an open cut in the ledge, is
., follows: Commencing from the foot,
the quartz-bearing porphyry is quite
hard and brittle until it reaches about
the middle of the ledge, where it gradu-
ally merges into crumbling yellowish.
brown carbonate Of silver; the head ore
carrying black sulphurets of silver, and
connected with the hanging wall about
two feet in thickness, the ledge carries q
soft, variously-colored chloride of silver.
Mr.. Carson considers the country be-
tween the two ravines the belt from
which all other veins in this section
start; that even the San Gabriel mines
are but spurs from this. It is commended
to be an extensive mineral deposit, and
that many other mines will be opened
out in the neighborhood within a few
months. No such mine--that is, carry.
ing this kind of ore-has ever been dis
covered in this State.
About a carload of ore has already been
taken out, and an assay will soon be
made. Mr.. Carson says that all the
ore is high grade; that there is no base
ore in the vein, therefore all the ore
that would be hoisted from the shaft
would be pay ore. He thinks the ore
will average between 500 and 5000 q
ton. If this is the case it would prove
to be an immensely rich mine, and large
camp would soon be established after the
mine was properly opened up. The ore
is quite soft and could be easily worked
1t would pay largely if it did not run
more than $25 ton.
Usually in the discovery of mines
large sums of money are spent in the
ondeavor to find the foot and hanging
walls. In this instance there was no ex-
pense, as nature had done that and left
| it almost exposed for the prospector.- -
