, period Of preparation Tor Blngham' for
/ while new mills and smclters have been
building, or the existing plants en-
! larged, managers Of the various mines
| have been making ready for the call
| that Will be made upon them during the
early part OF 1907. Ths great center Of
interest has been about the properties
of the Utah Copper, Boston Console
dated ana Utah Apex companies. The
first two mentioned have introduced the
steam shovel method Of mining and
have several machines in the
copper bearing porphyry belt engaged
! in stripping the ore Of overburden. BY
the time the Garfield mills are ready;
the mines will be ready to supply them
with ore. The Utah Copper w,l
| want 1000 tons .er day and the Bos-
! ton Consolidated plant when all the
units are complete, viii require 5000
tons, the Utah Apex and Utah Develop
mert viii start off with 800 tons and
the Ohio Copper has plans well maturei
TO build additions to It's plant and the
Yampa Smelling comnanv operating
the only smelter within tho limits Of tho
West Mountain, or Bingham district IS
adding more furnaces 10 Is estimated
that the present daily output OF ore
from the mines of Bingham Is between
5000 and 1900 tons. but a year from
now It viii probably be between 1900
and 10000 tons.
COPPER PRINCIPAL RESOURCE.
While the mining OF copper ore repre-
SCENTS ;he principal resourts Of the dis
trict the production Of lead ore rs by
no means unmgortant. The United
states Mining company finds 1t pronta-
bic to extract lead ore from It's Galena
mine, the Bingham Consolidated from
its Lark and Lead mine veins Lead
cuts an important guro IN the shipments
being made from the Phoenix and the
same Is true with the Utah Apex. Utah
Development. New England Gold &
Copper and Bingham- New Haven
minos. The lead ores at present being
worked range from 10 20 35 per cen
lead and from ; 20 Is ounces I'm silver.
The copper ores are two general types.
VIZ, sulphlde ores occurring In the lime
stone as replacement deposits and the
silclous ores. The replacement ores
are characterized by a heavy excess of
iron and carry from To Is per cent
copperaverae ing about TO 3,j per cent
AZ mined, The copper ores also carry
from 81 to 81 In gold and some silver
The replacement ores are treated by
smelling. The siliciOus ores arc Of two
general types, viz, the low grade por-
phyry ores averaging about per cent
copper and 03 IN sold which under go
the process OF concentration, the pro-
duct usually have an excess of from 10
to i5 per cent silica and In that cOndl.
ton is sent TO the shelter. Tno second
type Of silcious ore occurs In the assure
deposits Of the uuart2lta This ore 10
also OF concentrating class and when
treated shows an iron excess OF from S
to Is per cent
TYPE OF ORE DEPOSITS.
The ore deposits are OF the three gem
eral types, viz the true assure veins
the replacement deposits in the lime
stone and the low grade mineralized
porphyrles. But the true assure depos-
It's. according to well Informed engi-
neers, are rare. Among them are the
Galena, Phoenix, Wnncmuck and some
OF the veins found IN the Columbia mine
OF the Ohio Copper company With
the exception Of the latter all are lead
deposits.
The replacement deposits are mainly
copper ores, but there are some replace
ment Of lead In the limestone where
the lead fssurs have cut IT, These min.
erallzing assures have general north
east-southwest direction Wherever
they have cut the different bands OF
limestone che ore bearing solutions have
had chance to eat out in the lime
and form large deposits OF ore extend
ing literally from the hssure along the
east and west striking limestone. Where
the Hssures are IN qunr,zite, there has
been no naturalization. and the assures
are small IN addition 10 being practlc-
ally barren.
PoRPHYRY ORES LOW GRADE,
The porphyry ores are low grade.
They consist Of hrecciated monzonita
porphyry, which has subsequently been
mineralzed, mostly with chalcoclte and
bornite Of copper, This porphyry show
up more pronounced In the property OF
the Utah Copper and Boston consolidate
ed, although II extends into the Starless
group, owned b. Col +. A. Wall, and
through portions OF the Ohio Copper
company's ground.
The principal mining OF the district IL
carried on by big companies, although
there are great many small proper
ties being operated on a smaller scale
and probably,
