LETTER FROM PLACERvGLLE.
EDITOR WonLo:-This spring is a
sorry one for the placer miners, and
unless warm weather comes in with
May bees the season will prove a
very poor one to men who own bitches
and deep diggings. None Of the
claims have full heads of water.
However, there is good deal OF
snow in the hills and mountains winch
makes miners hopeful for an average
seasons run.
The newest thing in and around
this city is mill site at the mouth of
California gulch and junction with
Wolf creek. The site is a good one
and can be furnished with abundance
Of water that does not freeze in the
winter time. The mill may be ready
to run by the FIRST of August.
A visit to Quartzburg proves the
oft repeated assertion that the Gold
Hill company's mill never stops day
nor night only as necessity requires
to clean up, and that is only bat
terry at time. The mine is worked
City feet in width at present and gives
about the same results it has for
years; say about eight to ten dollars
per ton.
have heard that it is Dave Cough
anour's intention to start up work on
the Iowa mine as soon as material can
be got on the claim. The Iowa is
one of the coming properties on the
Gold Hill belt, and when Dave took
hold of that mine for FIVE thousand
dollars he felt that he had as good as
made twenty thousand on that day.
| met Dave to-day and We called at
the sulphuret plant and found Mr..
Gear ready and willing to give any
information concerning the process
that was desired. They are working
about ten tons per day at present, but
expect soon to increase the capacity
to thirty. They are now using less
than one pound of cyanide per ton
and seven pounds of lime to the ton
amounting, all told, for chemicals, tc
less than one dollar per ton. The
lime solution is applied every eight
hours and the whole solution remains
in the tanks twenty-four hours, il
then drawn off and pumped above
and allowed to leach the zinc shaw
ings which are placed in long tank
twenty seven feet in length, will
gates about two feet and half apar
which form small tanks which holC
the solution over the zinc shaving
about ten inches deep, but at th'
same time is leaching through tn
zinc shavings slowly, and continue
to do so as long as the shavings ar
black or show coloring while leach
ing. So long as there is colorin.
there is gold or silver, or both, TO
both metals are saved by the process
The strangeuess of the operation t
me is that the solution has no actio
on any other metals than those men
toned, lead and telluride not except
ed. 1t does not matter. Quart
, with the precious metal can be treat
, ed equally as successfully as sulphr
rets. All minerals are robbed of the
treasures alike, leaving the residue i
the tanks to be piped out preparate
rv for the next batch. Mr.. Gear tel
5 me there is no probability of dout
as to their working every kind of bas
metals that are found on the Col
a Hill divide. Mr.. Benham and M
!. Gear have the exclusive right fc
!. Boise county to work the process an
| believe they are men who do M
. want it all. The company grantin
S the right to work the process bine
{ them not to charge over a certai
, amount for working ores. TT
5 amount | did not take the liberty
inquire, but feel certain that ores rul
ming twelve dollars per ton will gi'
