Rich Strikes Are Made in Old
California Mines
Nevada County Boasts of Fifty Eight
Years of Continuous Production

VI SdlllOEHla mines contain low SIdIt
ledges on the whole, with rich streaks.
Economies in the mana cement and
operation are essential to success.
Once these are attained the practical
Permanency and growing prosperity OF
the quartz gold mining of this state
are assured. The great paying gold
mines of the world consist generally
of large deposits that produce low
averages per ton of ore, but embrace
vast ledges that run down to depths.
The Treadwell mines in Alaska are ex-
amples of the value of low grade propc-
sitfons where they can be worked ut
a profit The Amador Ledger says
that as far as oil is concerned the
question is solved for the Kennedy
mine.
IN VARIOUS DISTRICTS
Considerable mining progress is re-
ported in the Crackerjack district in
San Bernardino county. A ledge has
been struck, so it is reported, by the
Crackerjack gold mining company in
the King Solomon's shaft at depth OF
50 feet that gives an average assay
of 81 a ton. A contract has been let
for the construction OF double COM
partment shaft in the Beau Brummel
group, which will be run down 400 feet.
A contract has been awarded also for
the sinking of a shaft to the depth of
100 feet on the Peterson property.
Clearwater springs have been pur-
chased by Crackerjack men to supply
water to the district and a company
has been organized to pipe water to
the camp.
The Butte mining and development
company has been Incorporated to ex-
plot the Westcott property on the Ma
gala ridge in Butte county, near Sky
high. G. W. Braden is the presi-
dent of the company Development
work has been done to some extent.

The supervisors Of Sacramento
county. have denied the petition of
the Folsom development company for
permission to close certain streets at
Folsom which it proposed to dredge
for gold. Three streets were included
in the terms of the petition which was

Lively times at Kennel are reported.
The northern smelter town receives
carloads of ore daily from mines in
the Centerville and old diggings dis
tricts. One hundred carloads of
coke were side tracked recently
between Red Bluff and the smelters.

been running steadily for 60 days. Four
carloads Of matte have been shipped
daily for two months to the company's
refiners in Utah. Quarries are turning
out lime rock for the smelter use.
INTERESTING RESEARCH
Investigations OF great interest to
the mining population OF Trinity
county are in progress. The United
States geological survey will make a
contour map of the county. Survey
ors have been taking elevation at
Mount Bally and about Weaverville to
determine the heights of some Of the
larger mountains of the county. The
preliminary work for the contour map
was begun some months ago. All the
creeks. trails, roads and all other
physical peculiarities of developments
of the area that is mapped will be
shown. simultaneously an investiga-
tion is in progress to determine the
sources Of the great deposits Of gravel
in the Weaverville basin. A deposit
has been found in Garden gulch. so it is
reported, that resembles the gravel
found at the La Grange mine. The
last mentioned investigation is carried
on privately by geologists who are
interested in the county.
A smelter will be built near Pres
colt that will cost s1.ooo.0O0. An ad-
dition to the custom smelter at Hum
boldt, south of Prescott, will cost
100000. The Old Dominion works in
the Globe district, on which $1,000. 900
has been expended, will be enlarged at
once by the addition of new furnace,
the fifth to be constructed for the plant.
which will be open in July, and sixth
furnace is planned.
Two deals for mining property OF
some size in Arizona are reported. The
Mccarthy Mccormick group of copper
and gold claims on the Gila river has
been taken in by w. H. McKinnon for
$4,000. An offer OF s1s5,00O has been
accepted for copper claims owned by
IL c. Putnam and others, situated east
of Salome in the Harqua Hala noun
tains.
