SOMETHING DOING
ON BEAR RIVER
How Mining Is Looking Up in
Various Parts of
California

The Bear River tunnel company has
been incorporated in Nevada county to
run the property formerly owned by
the Bear River consolidated mining
company. The ledge has been followed
by tunnel something more than 500
feet The local men who stood by
the enterprise and drove the tunnel
will receive half interest in the prop
erty. The officers are DR.. w. g. Thomas,
president; G. II. Barker, secretary; Ne
vada County bank, treasurer; b. A
Penhall, superintendent. The directors
are DIR. Thomas, William Sampson,
Frank Hooper, William Wheeler and

an uplift that occurs in almost the
exact center of the crater, around the
edge of which is grouped the larger
mines of the Goldfield district.
1t has been the theory of local mineralosists
and geologists that no would ever be found
within the periphery of the crater ana most OF
the wise mining men have confined thelr enorts
to the edge of the basin. e. W. Hays has
secuted the idea that no ore would be found
within the crater and he has been dhhgently
working ON vindicator mountain, which lies about
3 800 feet north and east of the most northeriy
boundaries of the Consolidated acreage, and
north of the Lone Star group on whlcn some
minor strikes have lately been reported

The Round Mountain Nugget says
there is a good deal of activity in JET

the way for the construction of a 90
ton mill and $4,000 cyanide plant.
All the lumber is now in Austin, loaded
on cars at Battle Mountain. Three cars OF
machinery have arrived and six more carloads
on the way.

Howie, well known miuwright and engineer OF

The Graupner mill is on the Huntington plan,
with numerous notifications and improvements
which were invented and perfected by the man
from whom It gets its name. He was a sales

This low grade ore is used at the start in
