President Hallock, of the Colorado
and HALEY Iron Works, who returned
from the Carnas No. 2 mine last even.
ing, brought the welcome intelligence
that the FIRST cleanup Of the new mill
was completed and that the result
was about l6t pounds of amalgam
from which about five pounds of crude
bullion 600 fine was obtained, worth
about $l2 per ounce, $16s per pound,
or about $40 altogether. The bull
lion was to be brought in to-day or
tomorrow, to be remelted into bar,
and assayed for sale to. the United
States mint or in the New York mar
ket. ~
The mill was started up Sunday
morning, the 3lst ultimo, and ran
until Tuesday of this week, when the
stamps were hung up and the mill
cleaned up. The mill being new
there were many unavoidable stop
pages from various causes, and the
actual running time did not probably
exceed SIX full days of "a hours each.
During that time about 70 tons Of
rock were put through. The yield is
therefore At the average rate of about
$12 per ton, and the average work Of
tho mill was some IL tons per day
The ore was crushed sufficiently fine,
as 60-mesh ii. g. 60 meshes to the
square inch) screens were used; but
it is evident that, notwithstanding
the delays incidental to the starting.
up OF new mill, in an entirely new
district, on untried ore, the tineness
of the screens greatly initiated against
the capacity Of the mill, as $50 OF
500. pound stamps should crush two
tons per day of quartz of average
compactness (such as is the. Camas
ore) even when fine screens are used
The yield does not fully come up te
the public expectation, as the ore wa.
said to assay al average Of $35 PEI
ton; but as mill-runs seldom come w
to the assay value, this is not surpris
ing. Besides, the ore put through
was from the surface, and therefore
mixed with more or less waste. Tn.
mill will do better as it settles dow
to its work, and every cleanup vii
doubtless show an improvement unit
the maximum shall have been reached
The cost of mining and milling the
superintendent places at about 81 PEI
ton, and he expects, as soon as h
shall have added ten more stamps, t,
be able to reduce the expense to S2.7'
per ton. This can also be bettered
by adopting sclf-feeding machinery
which is comparatively Inexpensive
In California and many other gold
producing regions the ore is handled
but once during the whole process O
mining and milling, and that is t
shovel it in 4 car in the slopes. TIL
cost of reduction is therefore reduced
to such an extent that gold ore carry
ing only NINETY CENTS per to-
is worked to profit.
/ The ore being perfectly free, an
easily worked by the ordinary mi
process, the gold belt will be an i'm
portaut factor in our future prosper
ity. There are at least seven well-dt
fined parallel veins in that belt, O
, each of which are many locations, b.
, very little work has been done upo
E most OF them. These veins are know
