al English syndicate declares his report his
clients that the camp is a permanent one. that
great values will be opened UP at depth and that
the future prosperity of the district will rest to
great extent the extensive operation of milling
plants what he medium and low grade
He is of the opinion that the erection of
these plants in Cobalt will result in placing the
; best properties a steady dividend basis. Many
OF the progressive companies in the district have
long foreseen this. and during the last summer
several milling plants 10 be operated the lines
suggested by the engineer, have been erected. The
Coniagas, Mckinley-Darragh and Cobalt Central
mines have recently put in operation effective mod
reduction works The Cobalt Central plant is
the largest and most substantial structure of the
character that has thus far been erected Ricketts,
& Banks the mining engineers, made numerous tests
Cobalt Central before the specifications for
the machinery drawn. The plant finally
constructed was designed to carry out recommends
tons based on these tests. which took place at
Waverly, y. J. AS a result of these preliminary
tests, Ricketts, e. Banks gave it their opn-
ion that q saving of 80 per cent In metal values
could be made The plant has now been in opera
ton about month, and this prediction has been
entirely fulfilled. Experience has shown that this
average saving be made while operating the
plant at full capacity.
The Tr-Bullion Smelling and Development Com

80 per cent OF what the present plant Of the old
company is costing. The management OF the
pany says there IS difficulty in disposng OF
the zinc-lead pigment. which until recently

The cost Of making it at Canyon City is about
and one-tenth cents pound, which includes the
total operation. To this price must be added the
freight charges to market, one-third Of cent a
