ing being done here as early as 1919.
1t was also one of the richest camps in
the mountains. One dealer alone, who
operated here in early days, has a
record of buying in the neighborhood
of three and a half million dollars of
gold dust
AS the placers were after a time
pretty well worked out, the town be-
came dull-like many another mining
camp in the mountains-and remained
so until attention began to be paid to
quartz.
About ten years ago the late Hon. w
w. Stow purchased what is known as
the
GOLD BANK MINE.
1t is located on Forbes Ravine, a
quarter of a mile from ForbestOwn, al
an elevation of about $500 feet.
1t is large ledge of low grade ore
but by a systematic system of work
ing, and a complete and extensive
plant for reduction, has paid dividends
quite egularly-nUtwithsta the
immense amount Of dead and devel-
oped work which has all the time been
! prosecuted, since it was started.
The top works are extensive and as
complete as can be found on any mine
in California.
The hosting, pumping, and milling is
! done by means of water power, using
| 160 inches under about 200 feet press
ure.
There are altogether, large and small
twelve Pelton wheels in use in the diff
ferent buildings At the hoist there
are three-one to run the rock breaker
one to hoist, and one to run the pump
In the mill there are two wholesome
| to run the mill, and one the concen-
| traitor.
The rock breaker is a Gates No. )
which is located in the hosting works
The mill has forty stamps, each
stamp crushing three and a half tons
| in twentyfour hours. There are six
! teen Frue cOncentratorS. The Sulr
from the battery passes over an out
side plate and seventeen feet of apron
| and Sluice plates, also through sand
boxes and distributors, before reaching
| the concentratOrS.
| The material is then conducted tC
| two series of canvas tables, each OF
which have twenty-five sluices sixty
| Beyond these are settling boxes, and
still some of the shines escape, but the
| ore is probably worked up to a higher
percentage than most first class plants
| accomplish.
| The sulphurets are then chlorinated
! TIE plant having capacity of three
| tons per day. The sulphurets yield
| 500 to $50 per ton, and the shines
saved on the canvas tables, about
| twenty-five per cent. less. From the
hoisting works to the mill, and to the
| chlorination works is down grade, sc
everything moves down by gravity.
4 half mile below, about two years
| and a half ago, a crosscut tunnel was
started. which was expected to cut the
| ledge 800 vertical feet below the pres
| ent workings. A Union Duplex Com
| pressor 12x20, was lowered down the
steep mountain to that point in mid
winter, and work begun on a tunnel
| SxS in dimensions. Two Rand drills
working side by side, We're used. The
waste water from the upper works was
| picked up from the ravine and carried
! to a point from which an 11-inch pipe
| conducted it to the compressor works
under a 350-foot head. The tunnel is
now in $50 feet
At 1200 feet large formation sew
enty-five feet in width, was encoun-
tered. which contains a large percen-
tage of iron pyrites of low value. 1t
being in doubt whether this is the reg
ular ledge, the tunnel was pushed
ahead about 800 feet further. An up
