STAMP MILLS
FOR COPPER ORES
MetaIlurgist BEETLES Talks About
Boston Con, Experimental
Mill Work.
IS PLEASED WITH RESULTS.
Going to Alaska and Black Hills to
Inspect the Big Trcadwcll and
lIOmestatc Plants.

Stamp mills are destined to play an
important part in the future treatment
Of ore in Bingham.
The experimental plant Of the Boston
Consolidated. although 1t has been In
operation but about 10 days, has made
such favorable demonstrations In the
low grade copper bearing porphyries
Of that property, that there is no longer
any doubt in the mind OF chief Metal
lurgst A. j BEETLES that crushing by
means of stamps and the subsequent
treatment thereof. VIII prove to be the
most economic method of handling the
mill stuff of the Boston solidated
mine.
Mr.. Beetles, when seen by News
representative, called attention TO the
fact that some of the greatest mines IN
the world, productive OF large tonnages
Of low grade ore, are equipped with
stamp mills. For illustration he mem
toned the Treadwell. on Douglas island,
Alaska, the Homestake In the Black
Hills and several properties in the
Michigan copper country.
The work at the little Bingham plant,
which Ia equipped with a battery Of
Stamps, two whitley tables and "a Will
fey sinner has done all SO far, Mr..
BEETLES declares, that was anticipated
of IL. lie expects to be able to show
a fine record of extraction and to
prove the process w TO the satisfaction
of everyone concerned within the next
| 30 days This does not go to Indicate,
however, that the experiments Will be
concluded within that period. but Mr..
BEETLES does hope to have the case
practically settled then and with only
| the minor details left to be worked out,
1t seems TO be pretty well settled
| fact that In the Bingham porphyries
| the best results are obtained in ex-
| tracing values after the ore Is crushed
to a fineness hardly made possible by
| ordinary crushing rolls. and that Is
| the strong point in favor of stamps,
| which are capable of breaking from five
| to SIX tons OF ore every "A hours, and
| where the whole mass Is to be broken
| to certain fineness, II would seem that
| stamps, In accordance with Mr.. Bettle's
| idea, is the more preferable.
| Two points nre 20 be taken seriously
| into consideration in the treatment OF
| the Boston Consolidated porphyries.
| The first Is. the cost OF crushing and,
secondly. the amount OF shines made.
! Mr.. BEETLES says there Is no more eco
nomic way Of crushing than by stamps,
and that the ore will not slime as read

Mr.. BEETLES, after spending day at the
| company's offices, returned TO camp
this morning.
