they lie in blanket formation, in what
coal. These fiat veins are known as
chutes, and commonly trend in north
easterly and south westerly directions.
Some of them extend for distance OF
eight miles, and they vary in width
and thickness from a few feet to one
or two hundred. The first chute was
found in the everything white porpyery'
and this was the one that made Lead
vile so famous in the early days, oV-
er $780, 900 being extracted from 1t;
What led to the confidence that gold
could be found there?"
1.-THE United States geological survey
Samuel F. Emmons, who had charge
of the surveys made in 1881, DECIDED
that underlying the first chute OF silver
and lead, were others containing goa
and "copper" as well as silver, lead ana
manganese iron, and in 1893 party OF
gentlemen largely interested in the dis
trict, determined to prove his theory OF
the existence of gold, if possible. They
selected a property known as the Little
Jonney,' four miles from the city Of
Leadville. When they had sunk shaft
about 800 feet they encountered a body
of ore which showed free gold, and
much of this was worth from 81 to 81
pound. The discovery naturally
caused great excitement, and made
may other mine owners sink their old
silver mines deeper, and much gold,
silver and copper ore has since been
found. Since then it has been proven
that there are four distinct ore chutes
in the district, lying from 100 to $50
feet apart. All of these ores carry gold
values, particularly the lower chutes,
in what is known as the gold belt. In
other parts of the district they run
more toward sulphide ores, composed
of manganese iron, lead, silver and
some gold. These are much sought
after by the shelters at Denver, Pueblo
and Leadville for their fluxing quail
ties, it being absolutely necessary that
smelters should have lead and iron ores
to mix with the gold ores of Cripple
Creek and the silver ores of Aspen, and
other camps that carry no lead and iron
in them and which cannot be treated
in the furnaces unless mixed with those
metals AS the LeadVille ores carry so
many values, the shelters are glad to
get them, and make a small or nominal
charge for treating them. Leadville
miners have their business down on
solid, legitimate basis, and do not re-
quire stamp, cyanide, chlorination or
other kinds of mills. The ores are the
same as cash to the miner, as soon as
produced. The miners usually contract
with some Smelter a year in advance
for all ore produced. 1t is then shipped
to the smelter, and after it has been
sampled and assayed, the smelter pays
for it as received, taking New York
quotations for gold, silver, copper and
lead, as a basis for settlement. The
ores are then the property of the smelt
er and are mixed with other purchases
and put into the furnace. Ores from
dozen districts and containing many
different metals, may be melted to-
gether, and run out in molten mass
and cooled off in the shape of bars
weighing about 1000 pounds each, which
are shipped east to Perth Amboy and
Newark, n. j., where the reiners sep
crate the various metals into fine bull
lion.
I'm addition to the above valuable
minerals, zinc and manganese iron are
found in paying quantities. The zinc is
mostly marketed at a smelter built for
that purpose at Canyon City, Col, while
the manganese iron, which is found in
all of the old mines, having been left
in the workings of years ago, because
it did not pay for mining at that time,
is now being shipped to the Bessemer
steel works at Pueblo. Col, and to the
Illinois Steel Company at Chicago. The
latter concern took over 10000 tons dur
ing the past year, finding the man
ganese iron of a quality in every way
superior to that imported from Cuba,
and largely used by steel furnaces all
over the country. The zinc and iron
produced last year is estimated at from
100000 to 100000.
