contains forty stamps and two cylinder roasters, and is a
model structure in every respect The bullion product
runs from $50,000 to $fi0,0no per month, the ore being
worked to a higher percentage of its value thau in any
other mill in the district . W. A. Clark, the banker, is
president and general manager of the oompany. He is
also the heaviest stockholder.
Sihvr Bow Cbmwan.y. --This corporation owns a group
of mines among which aro some of the bonl in the din-trict-viz.,
the drey Rock, 300 foot deep; the I Plata,
350 feet deep; the Mount Moriah, 200 feet deep, and the
Belle of Butte, 300 feet deap. They are well devolojKHl
and productive properties, but cannot lie worked on a
scale commensurate with their magnitude owing to the
faot that the company has bnt a thirty-stamp mill iu
which to treat their product The mill is kept constantly
busy, and is producing 11,000 per day in silver bullion.
It is iu contemplation to double its capacity before the
end of the year, and the result will be the infusion of
new life in the development of the mines above named.
The Belle of Butte shows twelve feet of ore iu the lower
levels, the La Plata from four to six foot, and the Mount
Moriah three feet The first mentionod property was
one of the first discoveries in the district and has profits
of upwards of $300,000 standing to its credit
The other silver mills of the district are the Dexter,
with fifteen wet crushing stamps and a capacity of tweu-ty-eight
tons daily; the Old Lexington, with ten tanin
(dry), and the Clippor, witli five stamps (dry). Together
thoy are roduciug about forty-five tons of ore daily. The
stamps and amount of silver ore worked in the district
may therefore lie suimnod up an follows:

Anaconila. Chief among the copper mines of the
district is the Anaconda. Four years ago it was pur
chased by J. B. ilaggin, of Ban Francisco, for $.'10,000.
It is now rated as a fifteen million dollar property. The
expenditures for machinery, development and the erec
tion of a concentrating and smelting plant amount to
fully $4,000,000. The mine is opened up by a shaft 800
feet deep, from which, 100 feet apart, seven levels have
been extended in ore along the linlge, which varies in
width from forty to sixty feet every Puml ' Jt be'uB
workable ore. The product is divided into three grades:
The first class ore assaying from 35 to 70 per cent oop
per, mostly copper glance, is shipped East in a crude
state. The second class is treated at the smelter, and
.assays from 18 to 35 per cent The third okas is oouoou-
tratcd before being calcined. It carries from 10 to W
per cent before the iuitial treatment The Auauonda is
equipped with tho most powerful u.L'uuiy ou Ho
Facifio Coast The plant is oomplcte in every detail,
from hand drill to mammoth air compressor. The present
hoisting capacity of the machinery is 1,000 tons per day,
which, howevor, is considerably loss than the productive
capacity of the mine.
The Anaconda smelter is the largest enterprise of its
kind in the world. It contains tweuty.six furnaces, which
daily reduce GOO tons of ore, producing uinety tout of
matte, assaying (SO per omit oopper. The machinery lu
the entire plant is run by water power, though the fur
uaoes consume ninety cords of wood daily. The concen
trator and smelter buildings are the largest structures iu
the Rocky Mountains, and the marvel of the many hun
dreds of visitors who flock to see the " Montana Swan
sea," as Anaconda is enllod. The company has recently
let a oontraot to Caplioe & MoCune for 300,000 cords of
wood, which is now being delivered, and which will cost
over $1,000,000. This item alouo gives au idea of the
immensity of the works and earnestness of the oompany.
The Anaconda mine is conceded to lie the greatest ooper
property in Amorioa, and when the contemplated in
crease is made in the capacity of the concentrator ami
smelter, 1,000 tons of ore will be daily extracted ami
reduoed. The company gives direct employment to BOO
men in Butte and Anaoouda. Marcus Daly Is General

The mine is 350 feet deep and splendidly developed. It
daily produces 350 tons of copper ore, averaging in value
17 per cent oopper. The smelter is au extensive affair,
with eleven reverheratories, six mittlng furnaces, two
blast furnaoea and a concentrator, capable of handling'
300 tons of ore every twenty-four hours. The company
last year produced 9,400,000 piumls of pure oopper.
The capacity of the works has been almost doubled this
year, and new and improved process of preparing the
ore has been introduced. The oouoern will produce this
year about 15,000,000 pounds of pure oopper.
Montana Coiihim. The Montana smelter is almost
as large as the Parrot having six matting furuaws and
one blast It ore supply is drawn mainly from the
Colusa mine, which is fully develop! to a depth of 000
feet The vein varies in width from six to twenty-twu
feet and has been, ami is now, wonderfully productive,
having for the past live years maintained a eoutinuoua
production of 100 tons of ore per day, carrying both
silver and copper, thus giving an added richness to the
matte product The machinery equipment of the oom
pany is perfect The concern is now actively developing
two other oopper properties whose exteut and richness
are fully as great as those of ths Colusa, In the lower
levels of all the company's miues i umeuse reserve of
ore are in sight
Colorado. This is chiefly operated a custom suvd
