STILL MAKING TESTS.
Nature of the Plant for the Golden

Nature of the Plant for the Golden
Gate Not Decided Upon Yet.
Contrary to expectations, the nature
of the plant for the Golden Gate was
rot decided upon by Captain De La
mar prior to his departure for New
York. The experiments are still be
ing made, however, and some of them
are of an extensive nature, while al!
are thorough. The captain stated be-
fore leaving the city that he had
about made up his mind, but wanted
to be perfectly certain before taking
the important step of equipplng his
properties with a plant of the proper
tons intended. 1t is understood that
the mill to be placed on the proper
ties will have a great deal heavier ca
pacity than any now in use in the
district. Captain De Lamar never
is certain of his ground, then his work
is magnificent. Meanwhile the deVel-
opment of the Golden Gate and neigh
boring groups controlled by the cap
tain is to be carried on after the man
ner outlined in yesterdays issue of
The Herald-that is. by means of IN
foreground workings from the former
group. The showing of ore is now
something wonderful and the captain
suits that have been attained.
1t has been announced from head
quarters that in the event of certain
results being attained by the Pelatan-
Clerici process. the latter will be
adopted by the captain for the Golden
Gate plant. The owners of the method
are hard at work on ores from The
property and are of the opinion that
they can lead all competitors in the

This process is being put in at the De
Lamar mines. in Idaho, and on this
subject the Western Mining World
says:
Operations at the De Lamar mine
continue with the regularity of clock
work The mine is producing about
the same amount Of ore each month
and the exploitation and development
work on the property is kept up to a
standard commensurate with the re-
qulrements. Just now the work of
eXcavaung preparatory to the CON
structiOn Of a 50-tOn chemical plant is
going on. The plant is to be Pela-
tan-Clerici. which. from tests al
ready made. seems to suit the ores &C
this district much better than any
other chemical process introduced, says
the Statesman. The Pelatan-Clerici
process, as it is named after the in
by cyanide of potassium and precs:,:-
tation by an electrical current "a
ore, being first crushed to exceeding
ffneness. is placed in teaching vat of
wood or masonry. The bottom of the
vat is copper plate, which is con-
nected with the negative pole of a
dynamo. Through the center of the
vat runs shaft, from which radiate
arms that serve to keep the contents
stirred up as the shaft revolves. To
this shaft is connected the posi-
tive pole Of the dynamo. The
other plates in the bottom of the
dynamo are covered with mercury,
the crushed ore put in with water 10
hold it in solution, and the usual guam
tity of cyanide. AS the cyanide does
its work the shaft revolves, and the
freed metals are deposited upon the
amalgam in the bottom In from eight
to ten hours the process does its work
so that the ore solution is ready to be
drawn off and after that is done a
second vent is opened and the ANAL
gam drains off, and is separated in the
usual way. 1t is claimed for the new
process that 1T works a saving Of time.
requiring fewer vats. and consequently
a smaller plant. and is less expensive
than the old cyanide treatment.
