The mine Is opened by two tunnels.
The upper, or Yampa tunnel is $50 feet
below the crest OF the mountain, and
In this adlt a vast tonnage has been
blocked out.
In the Craig, or lower tunnel, great
showing OF ore Is In evidence, This
tunnel cut the ore body 1900 feet from

THE YAMPA SHELTER.
The Yampa Smelling company is the
owner OF the reduction plant located IN
lower Bingham canyon, about a mile
above the big concentrating mill OF the
Utah Copper company. II was built
expressly for ores produced from the
Yampa mine and Is the only smelter
operated within the camp. Excepting
IN this instance oil the Bingham ores
are brought down to either Bingham
Junction or Murray for treatment. II
was originally planned that the fampa
smelter should consist only OF one
roasting furnace and one blast furnace;
but soon after the plant was blown IN
