Work on Many Large Projects Causes
a Revival of Interest in Mining

While there have been no recent
California. revival OF mining in
terest is being manifested, unmistak-
ably, by the large number of projects
for mining development in various
California mining districts.
The old Excelsior gravel mine, just
south Of Placerville. has been practi-
. cally rehabilitated by the FL Dorado
Water and Deep Gravel Company. as
the result Of two years of work under
the direction Of A. Barring Gould. The
developments include 5000 feet Of drifts
aud crosscuts The main tunnel where
the most work is in progress. is in
5000 feet. Two bodies OF pay gravel
have been discovered. so says the
Placerville Democrat. A 10-stamp mill
has been installed.
Work has heen resumed on the Rain
bow mine in Sierra County. This was
formerly a large producer. The chute
was run on an upraise to facilitate
the handling OF ore. which carried SUI
phurets and free gold
The Giant King mine. so says the
Grass Valley Union, is likely to become
large producer Of low grade ore. The
mine is near Washington, Nevada
County Two tunnels are run. one OF
which, now in $40 feet, has cut large
ledge. and the other viii be extended

sion Of the Cooperative Exploration
and Development Company. A 2o-stamp
mill VIII be constructed.
SLATE MINING Is ACTIVE
Slate mining IN Ell Dorado County
has been largely increased since the
San Francisco fire. The shipments Of
states for roofing and tiling amounted
last year to hundreds OF carloads. The
slate deposits at Chile Bar and just
north Of Placerville are OF great size
and are supposed to be the equal in
extent OF any in the world Stating
ton, a town growing out Of the slate
production, is busy and growing
camp, with a postoffice and school and
other conveniences.
The mines Of Plumas County viii be
greatly helped by the operation OF the
Western Pacific road through Plumas
County The Greenville mother lode"
says the Plumas Independent, ranging
from TaylorviIle through Crescent
Hills nOrthward 10 the head Of Wolf
Creek, shows an unbroken continuity
Of Lodges for distance Of fifteen miles.
The mines along this lode have. in the
course Of half a century, produced
