No. 1 mine and the Mississippi claim,
also located in the West Mountain
mining district.
The Commercial mine. situated at
the head of Copper Center gulch In
main Bingham canyon. consisting OF
62 acres of the mineral zone and COW

| feet.
| The formation consists of limestone
and quartzite. with occasional por-

The ore is a copper iron sulphide car
rying gold and silver, and is a re-

WORKING AT COMMERCIAL.
The Commercial Is developed by
two cross cut tunnels. Commercial

distance of LOO feet to intersect
The zone, from which point 1t was
driven In 4 southwcsterly direction
on the strike of the lode for q distance

tonnage of ore that has been mined
and shipped to the smelters in Salt

driven in southerly direction for
LOO feet. where IL also intersects
the lode, developing ore the entire
length of tho vein within the limits
OF the property. and to q depth of
$50 feet on the plane of the vein; in
addition to the above openings. an
incline shaft has been sunk in ore
from the lower tunnel on the plane of
the vein to q depth of $50 feet;
levels have also been driven in orc
from the incline easterly and west
erly entirely across the property, de-
Veloping close to 100000 tons of cop
per sulphide ore The physical con-
dition of the property is excellent and
the equipment complete, making 1t
possible TO produce ore at a minimum
cost.
On account of the closing of the
companys copper smelter at Bling
ham Junction by the United States
court in the fail OF 1907. the Com
mercial was forced to shut down. but
in June. 1909. a satisfactory contract
1or the treatment Of the ores of this !
mine was secured from the Yampa |
smelling company. and since that !
time. the mine has been actively |
worked and the product shipped over |

DALTON AND LARK MINES.
The Dalton and Lark mines embrace |
several groups, situated on the eastern |
slope of the Oquirrn range on the |
eastern side of main Bingham canyon.
formerly operated under separate |
management, and known as the |
Brooklyn, Dalton & Lark, Miners |
Dream, Sampson and Lead mine COM !
prising an area of 240 acres of the
mineral zone and $50 acres of nom
mineral land, covering a portion OF |
the Mascotte tunnel and affording |
ample space for ore bins. power |
plants. dwellings, dumping ground and !
reduction works.
These groups have three veins, or |
parallel belts of lime. varying In |
horizontal thickness from 10 to $50 |
feet, alternated with belts of quartZite. |
with a strike north 80 degrees east |
and northwesterly dip OF 40 de- |
grees These veins are designated as
the Brooklyn Miners Dream on the |
south. Lark Yosemite In the center.
and the Lead mine vein on the north
The Brooklyn or Miners Dream lime
belt Is the largest. Its narrowest
known horizontal thickness Is 10 feet
and its widest $50 feet The Bingham
Mines company's property covers
100 feet of this vein, 1900 feet of |
the Lark Yosemite vein and approxi-
mately 500 feet of the Lead mine |
vein. Like the other lime formations
of the Bingham camp, these veins are
inter5ected with numerous cross fis-
sures but there is less evidence of |
faultIng in this portion Of the dis
trict than farther west. Bunches of |
porphyry and porphyry dikes are |
numerous. The Lark-Y osemite vein |
consists of a narrow belt of lime |
varying from a few inches to 30 feet |
In thickness lying between quartzite |
walls. This vein has IN all probability |
produced the richest ore, In large |
quantities, of any lime deposit In the |
Bingham district The ore shoots are |
remarkable for their length on the |
strike OF the vein, and their persis- |
tency with depth. The shoots vary |
