NEWHoUsE AND BOSTON CON.
Boston Consolidated is q promotion Of
Samuel Newhouse and he looks upon II
as being his most successful one. There
is no doubt but that the Boston viii
become a big producer Of copper and
one OF Binghams substantial dividend
payers. In reality there are two mines
In one and they have been designated
as the sulphide mine and the porphyry
mine The latter covers an immense
area OF territory and the company has
two steam shovels engaged IN clearing
the surface of overburfen prepare tory

The company Is constructing a large

ranging from 20 to 70 feet In thickness.
This waste, after being moved by the
steam shovels Is loaded into cars nn1

TO examine the mine recently figured
that the bornlte and chalcocite, Sec

Newhouse and his staff have made a
very careful investigation Of operating

be mined and marketed for as low cost
as 81 10 per ton and II Is figured that

It is figured that the mill as II Is be-

that the plant will go into commission
before next June. II Is estimated that
there are more than 10000 tons OF ore
In sight IN the sulphide mine which car

from 2la to per cent and the gold and
silver values from 50 80 to 50 per ton.

the company should earn annually
around "a share on the $4,000 shares
outstanding. With greater mill IA

be correspondingly greater.
UTAH CoPPER's MAGNITUDE.
There are not very many mines any
where that are bigger than the Utah
Copper of Bingham. The ore bodies
OF this property consist OF low grade
mIneralized porphyry described In ref
erence to the Boston Con. The big
copper magnates Of the country did
not begin to appreciate the magnitude
OF the camp until this company DEM
onstrated the probability OF treat
Ing these great porphyry deposits. The
success achieved In this undertaking
set mining men to thinking and the
lessons learned In Bingham are being
applied advantageously In the opening
or other copper camps. Conditions
are somewhat similar IN Ely. Nevada,
so the solving of the problem Of ore
treatment for that camp turned out to
be easy. But TO Col. T.. A. Wall be-
longs the credit Of Strengthening out
some OF the things which stood In the
way Of progress at Bingham. Fiji
teen years or more ago he acquired
the ground now owned by the Utah
Copper company. Although the price
OF copper was low then he could see
the light ahead. He believed that the
time would come when the low grade
porphyries would be proftably ham
died. Realizing that It would require
the investment OF large amount OF
capital 10 carry out the enterprise. But
others could not see as he did: that
the time would come when the ground
would form the basis for a wonderfully
profitable concentrating enterprise.
Finally, the colonel interested Captain
j. r, DeIamar, to whom he trans
ferrcd a ono-half interest In tho prop
erty. But beyond prospecting the
