SILVER MINING-PARS CITY.
The greatest camp is city 30 miles
cast of Salt Lake. 1t contains some
of the largest silver mines in the world.
\ cubic ward of the glistening galena
that lines the dark, deep tunnels may
be worth $500. ore valued at millions
Is in sight. but far underground, 10
which the miners descend and from
which the ore is lifted through narrow
openings (shafts). Down the main
shaft an elevator drops" or rises with
amazing swiftness. controlled by large
engines. The mines run "a hours uer
day, Sundays and all, the men working
in eight hour shifts" They drill little
holes into the breasts of ore, fill them
with giant powder, and explode them
when that particular tunnel is vacated
Cars drawn by horses that may never
see daylight, carry the ore to the main
shaft.
The ore is ground. then sifted. then
either jlgged in water or passed over
shaking tables, till the heavier par
ticles, or concentrates, are separted
from the lighter or waste material
The mill is so arranged usually on Il
hillside, that the water used I'm wash
ing the crushed ore falls by gravity
from each higher to a lower level The
refuse, or waste, is carried away; but
the muddy water or slime is saved and
run through filter presses. from which
in the form of thick cakes. 1t is finally
dried and sent to the smeter.
COPPER MINING-BINGHAM
At first only those ores hearing silver,
| from to S TO 60 ounces per ton, and
| lead from 30 to 80 per cent, with
value in gold OF from 81 to 500 per ton,
were mined. Ores of lower grade and
| all copper deposits were neglected. In
| proved methods of treatment and
| transportation have so changed the
| mining industry that in 1906 the vast
| deposits of copper have caused Utah
| to rank fourth among the copper-pro-
| duCing states. Crude metallic or
| blister copper to the amount Of
| 5O.329,119 pounds was produced
| mainly from three important dis
| tricts-Blngham, Tintic and Frisco.
| The Bingham district, in Salt Lake
| county, Is sixth in Importance in the
| country. 1t has had Its gold. silver
| lead, and copper periods of production.
| The Tintic district, at Eureka, Juab
| county Is the second copper camp in
| the state. Essentially precious metal
camp, one Of the richest in the state,
| with copper, and lead as accompanying
metals, nearly every producing mine in
| the camp has added more or less cop
| per to the output. The average Yield Of
all the ores of the Tintic dictrict is
about per cent Of copper but certain
ores Yield much more. Low grade ores
In large deposits may be said to be the
! rule In Utah mines.
The Frisco district Beaver County
has been famous for Its horn silver a
| rich ore that may be cut like horn.
| Tho bulk Of the copper output for
1906 both in Bingham and Frisco
came from ores yielding a lower per-
centage of copper than any other
| large mines outside the Lake Superior
region; but low gold and silver values
! somewhat reduce the total expense.
/ The ore is concentrated about 10 to /,
and shipped TO Salt Lake shelters.
OTHER DISTRICTS.
To the east is Marysyale, containing
| mines OF gold, silver. lead. copper and
quicksilver When silver fell in value.
this camp declined, but the gold values
were later found to be very regular.
| Other principal copper regions are
| the Little Cottonwood district the Park
| city mines the Ophir district. and tho
| Tutsagubet district, In Washington
county In all but the last named
copper Is recovered incidentally TO tho
| production OF other metals.
| Gold Mountain In Pluto county; Deep
! Creek, $40 miles west OF Salt Lake city.
n great camp, now chiefly gold aud
| copper; and In the southeast the Ia
Sal, the Blue and the Henry mountains
| should be mentioned. Farthest south
| OF all is n copper silver region around
| ST. George, including the famed Silver
| Reef a mining curiosity. In an i'm
| mense reef or Ledge of sandstone is
found petrined forest, Occasionally
parts OF stone, trees and other rocks
| containing fossils are taken and millod
| for silver.
PRECIOUS METAL PRODUCT.
The production Of precious metals for
1905, Is as follows:
