BIG ORE BODIES
Of UTAH CON.
interesting Detailed Information
About Bingham'S Great Pro-
Queer Of Copper.
AS SEEN BY BOSTON EDITOR.
Some Figures Which Show the Actual
Costs Of Mining and
Smelling

George J.. Walker editor Of the
Boston Commercial. who recently Wis
ited several OF the principal copper
mines Of this state has been giving
out some interesting Information about
the properties which came under his
observation. Last week he told
story about the Cactus OF Beaver coun-
o. which the News reproduced and
which was read with a great deal Of
local Interest This week. Mr. Walker
treats Of Utah Consolidated. which H.
uow leading dividend paying mine Of
the state In his comment on this
big Bingham copper producer. Mr..
Walker says:
Utah Consolidated has added tre-
mendously 20 its ore resources since
] previously visited It's underground
workings | was through the mine IN
September. 1901. and az that time only
three distinct ore bodies had been To-
Gated and developed Since then five
more deposits have been opened which
compare very fayorably IN both size
and grade with the original three.
The last three ore bodies opened may
prove to be connected In which event
II viii probably be the largest as we'll
as the richest ore deposit ~ the mine.
NEW ORE BODIES.
The new ore bodies referred TO
were encountered in the exploratory
drifts as they approached what is
known as the 1874 fault This fault Is
about 1000 feet west OF the first ore
a.. 49, la
operations. Three drifts. two driven iE
nearly opposite directions and the
third az right angles, all entered high
grade ore. When / went through the
mine three weeks ago, two Of these
drifts were e1ch in ore 40 feet and
the other 20 feet and the ore exposed
averaged between and per cent
copper. about 81 gold and carried
characteristic values in silver
The point where these ore bodies
were cut is about 400 feet above the
companys working tunnel and 1000
feet west OF No. 1 ore body Their
phenomenal richness Is probably due
10 that secondary enrichment which
Characterizes nearly all deposits OF
copper ore near the surface. II II
proves 10 be secondary enrichment,
however. it will mean that these ore
bodies are Of fully as good character
at depth as the several others which
carried 81 10 3ia per cent copper in
the 7th and So levels, the deepest
openings In the mine
The entire operations Of the Utah
Consolidated 20 date have been con-
fined 10 strata Of limestone about
1000 feet long and 300 feet wide This
lime is tilted 10 an angle Of about 40
degrees and cut lengthwise by a mar
row dixie Of porphyry The first three
ore bodies were found cropping on the
surface and opened by a tunnel which
followed the footwall auartzite Three
or four years go Il came to be recog-
nized that these ore bodies occurred In
connection with cross faults which cut
the country north and south. Conse-
quentlv drifts we're driven north on
these faults and duplicate ore bodies
were found near the hanging wall OF
the lime north Of No l and No. ore
bodies. The three additional ones re-

driven beyond the fault mentioned, but

uy al the time 10 supply sufficient AR
Tor ventilation. 4 small body Of sill
yer-lead ore OF good grade was opened
nv this drift. There Is ever" reason
FOR the hope that the area beyond this
fault may also be productive OF most
excellent values The description
given Of No. and No. 2 north ore
bodies viii undoubtedly make Il plain
that they overlie the original No.
and No 2 ore bodies and dip al the
