ANNUAL REPORT,I9
MINING AND SMELLING
Ore in Sight for Many Years.
Interesting Facts Regarding
Greatest Lead Mine

IT HE ANNUAL report of the Bum
/ ker Hin x Sullivan Mining &
Concentrating company for the
year 1922 contains the usual
amount of interesting information
concerning the operations OF this Won
derful mine, which easily ranks as the
greatest lead-silver mine in the world
After 81 years of continuous opera
ton. during which time it has paid
dividends amounting to S27237OO
the mine today has ore in sight to in
sure production at the present rate for
nine years while the possibilities of
further development practically in
sures its productive life for many
years beyond that period. Aside from
its mining operations proper, the COM
pany has built up on a firm basis a
great lead smelling plant which is
steadily charging its field and swell
ing the profits of the company. Plans
have also been matured for the estab-
lishment of an electrolytic zinc reduc-
ton plant at Kellogg which it is I'M
derstood will be in operation by the
time the Star mine, owned jointly by
the Bunker Hill and Hecla companies
is ready for production. The Bunker
Hill company has also developed a
new electric process for the recovery
of lead which has proved it's efficiency
in an experimental plant. which is
soon to be followed by a commercial
plant In addition to these major
branches OF its ever-e expanding oper-
atoms the Bunker Hill & Sullivan
company maintains a staff of metal
lurgical engineers who are constant
ly engaged in experimental work with
the view to solving problems of ore
treatment and reducing the loss. AS
part of the annual review of the COM
panys activities during the year 1922
is the following report of the general
manager Stanly A Easton:
General Managers Report.
"Production for the year was close
ly the same as that for 1921, but the
better price received for lead resulted
in earnings much larger than those
made during the preceding year.
Thre has been some decrease in pro-
duction costs which still remain COM
paratively high.
1.-THE Bunker Hill smelter and re-
fnery operated continuously and sue
cessfully throughout the year and re-
ceived an increased amount of custom
ore. It produced substantially more
lead and silver bullion than in any
former year OF It's operation. Our
Bunker Hill brand of pig lead sells
rapidly and is highly acceptable to
all branches of the trade. It is now
difficult to fill all orders for it,
development of the lower levels of
the mine has proceeded uninterrupt-
edlv throughout the year. Extensions
Of the No. 16 level have been pushed
with very gratifying results, and sink
ing of the main shaft has been re-
5umed for the opening up of the No.
II level, which will be 1900 feet YER
.ically below the Kellogg adit tunnel
evel The ore occurrence and struct-
iral conditions in the lower levels are
iound to be entirely normal and the
IRE bodies disclosed are equal in size
md grade to the bodies found by the
upper or older levels of the mine.
"There is nothing Of unusual inter
st to report in the various develop
nent projects which we are conduct
ng or contributing to. The develop
nent of the Star mine in which we are
on an equal basis with the
Tecla Mining company has proceeded
egularly throughout the year. On
January 1. last 6S.S per cent had been
completed in extending the crosscut
rom the 2OOO-foot level of the Hecla
nine. which will reach the star vein
It great depth.
We have ore blocked out to date:
;temwinder mine ......... 1866 tons
sullivan mine ................... f23191 tons
Bunker Hill mine 3672 16O tons
