The San Francisco call. [volume] (San Francisco [Calif.]) 1895-1913, 1905-05-06


In San Diego County that may be
worth millions to California. Phos-
phate rock has been picked up as float
near Escondido and samples have been
forwarded to the State Mining Bureau
for examination.
The value Of phosphate rock is that
1t contains fertilizing material that can
be used for enriching the soil. Il the
rock is as rich as is supposed and the
deposit is large the result Of this dis
covery may be to add great values to
the mineral output of this State.
Two years ago, according to the re-
port Of the United States Geological
Survey the phosphate rock product or
the United States amounted to 1,oIo,-'
2SS long tons. The value of-this rock
was s4,993,912. That is, as will be
seen readily, the value per ton ran on
the average as high as many low grade
gold properties, that, worked econom-
tcally, are paying largely.
Phosphate rock has never been
known to California as native pro-
duct until now. North Carolina, South
Carolina and Florida have afforded the
principal If not the only native sup
ply of mineral fertilizers for the
United States.
Among the mineral industrial re-
gions of the country Florida alone
has made a show by its production or
phosphate rock and the reduction OF
the fertilizers for commercial use. IL
has brought out phosphate rock and
pebble phosphate quite largely. Some
of the rock has returned as high as
Is to 16 per cent in phosphortc acid,
which sells for about IS 40 a ton. This
is equivalent in value to what Is ac-
counted to be very good gold-bearing
rock.
The supposition Is entertained that
the surface indications Of phosphoric
rock IN San Diego County imply de-
posts of large size. State Mineralogist
Aubury has given directions that the
samples that have been sent to the
State Mining Bureau shall be treated
at once. Mr.. Preston Is making the
examination for the State Mining
Bureau that will determine the value
of the rock for phosphates.
LARGE PLACER DEAL MADE.
The most extensive deal in mining
properties that has ever been made
has, according to the Placer Re-
publican, been made matter OF rec
ord. Placer mining lands extending
along river banks to distance Of six
and a half miles above and below the
Cash Rock mine. have been secured
Republican says regarding the trans
action:
There were three locations Of leo acres
each. covering about six and a half miles Of
the Middle Fork, above and below the Cash
Rock mine The first the Lucille placer claim
takes in the river above Cash ROCK. running
up stream IL. 900 feet and being 600 feet wide
The second. the Francis placer mine com
mences at Cash Rock and runs down stream
l.. coo feet from that point and the Marion
placer claim, of equal size, Joins it on the
lower Side, thus forming area 600x36 600
feet in the three claims. Mr.. Trumbull
short time ago purchased the Dairy Farm
mine near Lincoln.
The deal for the Graham group of
mines near Copper City has been re-
corded. The price of the properties
The Redding Searchlight says about
the deal:
The parties to the agreement are B. A
Graham. P. F. Grant, H. Callaghan. John D.
Graham and Walter Bassett. owners in the
property and Philip Deidesheimer. the pres
pective purchaser. The Graham group is sit
usted Horse Mountain in the Pittsburg
mining district about midway between Copper
lowing claims: Old Missouri Caution, Cres-
cent, Gypsy. Queen, 1901 and Copper Belt
per Belle. American and American No. 2.
According to the terms Of the agreement
property by Mr. Dedesheimer after July l.
1905, and I'D to October Is, 1906, when the
full payment must be made.f A payment OF
$500 was made on the execution of the agree
ment. and the remainder of the purchase
price. $29, 500. must be paid October 49,
1906.
The Amador Ledger reports that
rich streak of ore has been discovered
insthe keystone mine. Mt the Fremont
mine, according to the same authority,
the levels are opening well. The ore
bodies are large and warrant the in
crease of the mill facilities to 100
stamps.
