Mr.. Henry w. Dorman, manager
OF the I. K. L. group of mines in.
the Pearl district, gives some very
Interesting and encouraging infor-
nation respecting the mining situa-
ton. He says the camp is showing
up splendidly. There is increased
activity all along the line. The
producing mines are becoming more
productive and development work
is being pushed with renewed ener-
gy. The cause of the greatly i'm
proved condition is that it has been
finally demonstrated that all the
ores can be reduced by the cyanide
process. Until recently experts
have held that the only way in
which the ores could be handled
was by concentration, but improved
methods, coming with a better
knowledge of cyanide, have made
it possible to employ the cyanide
process with marked success. A.
few years ago a Montana expert
spent several days experimenting
TOR Mr.. Dorman ON Pearl ores, and
the best results he could get from
cyanide un Ter the process then en-
ployed was a saving of AZ per cent
Of the values. On this showing
cyanide was necessarily abandoned,
and concentration plants installed.
Recent improvements in the cyanide q
process makes it entirely practica.
bic to save o2 per cent of the values,
and at one of the mines where the =
process has been in operation for
80 days or more this is actually
being done. Mr.. Dorman says the
problem is now solved, and Pearl
will soon become one of the greatest
mining districts in the west. The
cost of installing cyanide plant is
only about 90 per cent of the cost
OF a concentration plant, and the
same or a greater degree of saving II
is effected In operation. 1t is now,
quite practicable, says Mr.. Dorman,
to handle three dollar ore at good
profit. The economies effected by #
cyanide over concentration are
many. There, is first, the freight =.
ing of concentrates, then the smelt-
ing, then sacks and finally the great .
additional amount OF water needed,
and in the Pearl district water is a "
vital consideration. 1..'' 81, "a 3
Mr.. Dorman is one of the most
experienced practical miners in the
State. He located the I. x. L. j,
group and has other large mining
interests. His faith in I. K. L.
has never wavered although many
discouraging obstacles have been
met with. 1t seems that, at last,
all difficulties have been overcome,
and Mr.. Dorman is fully justified.
He is entitled to big reward and

A. K. Steunenberg and John c.
Rice of Caldwell were in the city
yesterday on their way to St. An
thony to attend a meeting of the
directors of the FirstS National
Bank at that place in which they
are interested. They state that
everything looks most encouraging
for Caldwell this year ano that
there is but little doubt but that the
great government irrigation pro-
ject for watering the lands of the 3"
Payette-Boise valleys will be car
ried through. There are now more
than 90, 900 acres of settled lands
which have been signed up for the
enterprise and the government has
more than 100000 acres of land
which is not yet settled which will be.
benefited besides several thousand
more belonging to the state.
Should this proposition be carried e.
out, Caldwell would be in the CEN
ter of one of the most magnificent
agricultural sections in the vest
