The week has brought two more important
deep-mining developments in the mot he lode.
In the Massachusetts Hill mine, Nevada
County, a fl ne body of ore has been struck in
the 300 level II is three feet thick aud indi-
Gates permanency. This old mine, which ad-
joins Grass Valley, is now In the hand OF East
ern people, who have bsel working and pros
pscting for year with little success. Tne
managers had confidence that they had good
mine, but could not discover the pay chute.
Their confidence and persistence have been
rewarded as such confidence is being re-
warded right along on the mother lode.
few days ago the strike of rich vein at the
1900 level of the rehabi itated old Gwin m inc
in Calaveras County was noted. During the
week a second find of a large body OF good ore
on the 14O0 level has been made. 1t is reported
that the ore will run into the hundreds per
ton These discoveries OF the deep value of
mother lode mines coming with increasing
frequency are Fastening great era of deep
aiming in California AT the Utica, One da
and other mines shafts are now being driven
to greater depths because of this confidence
and more discoveries will doubtless soon BE-
announced The idea that the values Of the
mother lode are not deep and permanent is be-
ing dispelled, and capital, especially California
capital, is ready to hunt for god by going
deep rather than by hunting for surface indi-
cations.
At the Rawhide experiments are being made
to determine whether oneentrating or
cyanide plant of 100 tons capacity shall be
put in.-During the first three months of this
year the United States produced 1929 tons
more copper than in the CORES pondlng period
OF last year. The exports showed q still greater
increase owing to the growing European de-
mand, and the outlook for the copper industry
| is bright.-Charles d. Lane has bought an

State Mneralogist Cooper is considering the
idea of taking up 10 the extent practicable, as
part of the work of the Mining Bureau the
study of the opportunities for the develop
ment OF electrical power in the mining re-
gions. This seems especially important TO the
Randsburg dis trict just now, as the question
of power will b. one of increasing Importance
| ss development proceeds. Should the veins of
that district prove valuable with depth, oper-
ations will be carried OH with difficulty snd
expense even when a branch railroad cheapens
a coal supply. The Kern River which, at diff
| ferent points, flows from forty to seventy-fve
miles distant from Randsburg. seems TO many
| to be bound a with the future of that desert
district The present electrical power plant
| on the Kern River is on its lower course and
| uses but about mile of the stream. Higher
up toward the headwaters are many oppor-
| tunities for using the power of the stream,
and with the recent successes in long-distance
| transmission, there seems TO be within reach
! of Ran6sburg all the power its mines will
need awaiting only the development of de-
mand that viii warrant great power enter.

Throughout the mining gions of the Sierra
Nevadas and the northern counties the de-
parture of winter snow VS. and the petite rment OF
the eroads have put into activity all the develop
ment operations which have been planned
within the past few months, ana the local
! papers every ywhere record the rapid erection
] OF mills and other machinery, the sinking of
shafts, the running of tunnels and the sale
ana bonding of mines The army of pros
pectors is out, and 1t is bigger than at any
season for twenty-five years. The reopening of
the old mines is being extensively carried on
One of the latest Is the old Calaveras mine
near Sheep Ranch, in Calaveras County which
has been bonded by San Francisco men. This
mine has been idle for ten years, though
500, 900 was taken out with 6O0-foot de-
velopment. The company proposes to put in
large plant and sink at once 10 1000 feet.
