Mining Items.


Two cars of machinery arrived the
forepart Of the week for the Ivanhoe
Gold Mining company. 1t consists of a
new boiler, air compressor, etc.
The annual meeting of the stockhol-
ders of the Boston & Wyoming Copper
Gold Company will be held at the Office
of w. E. Benedict in this city on January
18th, 1904.
Mr.. James Demereau has finished the
assessment work on Mr.. Fred Heide-
priom's claim southeast of town. In
performing this work Jim discovered a
new and valuable vein of quartz full
feet thick. The quartz is full of specks
of telluride and we'll colored with stains
of vanadium, 1t has the appearance of
being very rich ore but no assay returns
have been received as yet.
HENDRYx CYANIDE PROCESS.
DR.. w. A. Hendryx Of Los Angeles,
Cal, has recently perfected process of
treating ore by cyanide of potassium.
The doctor claims to be able to hasten
the length of treatment and lower costs.
Less expense is connected with the in
itisl installation of his machinery than
in the ordinary cyanide mill. Essential
ly the process consists of applying a
weak cyanide solution to the pulp and
during the teaching process the mixture
is subject to constant agitation, whereby
thorough aeration is secured, thus effect
ing complete contact of the pulp with
the solctiou. In this connection there
is an electrical precipitation of the gold
and silver on electrically charged copper
or lead plates. DR.. Hendryx is a prac.
tical operator and has spent several
years perfecting the process by expert.
ments at his own mines and mills, not.
ably at the Empire property in Yavapai
county, Arizona, of which he is general
manager. 1t would appear that no zinc
is used for precipitation as in the usual
cyanide process, nor does it appear that
mercury is used in connection with cleo.
trolysis as is the case with the Pelatan.
Clerici process. The result is obtained
and completed in one tank and it is as.
serted that the electric current brough,
into use in precipitating serves to regen'
crate a portion of the cyanide, making i,
amenable to use again. The fact that
DR.. Hendryx's Empire mill, near Pres
colt, Arizona, has actually treated good
many thousand tons of ore within the
last three years, with apparent success
speaks we'll for the process. 1t is claim
ed the time of treatment requires only
from two to six hours. The further
proving of the utility of this modification
of the cyanide process will be watched
for with rest.-Lead Call.
THE SUNBEAM NINE.
Geo. Smith, who last week returned
from the Sunbeam mine where he ha.
been engaged for the last six month";

on the 300 foot level. They have larg,
amount OF ore on the dump, and plenty
of excellent grade ore in sight to JUSTLY
the starting of the mill for continuou
run. This ore is largely free milling
but in common with the ores furthe
south it contains some which is com

that these combinations are found in tn,
mines in that district. He knows how

this we have but one remark to make
and that is, if they have not they ought
to have. But, no doubt, they will find
it out soon enough, and put in whatever
is necessary to complete their plant and
save the gold that is contained in their
ore. The company has kept in constant
