! Operations at the Ray mine and mill
have been suspended, and the Blade
has been informed by letter, from the
management, that the suspension will
| probably continue for six months at
the mine, unless the work of enlarging
the mill capacity at Kelvin can be CON-
| pleted in less time. The board of man
agement, in London, acting upon the
recommendation of general manager
Truman, has decided to enlarge the
mill, at Kelvin, to five hundred tons
capacity daily, and to install i50-
horse power steam plant of the latest
design, to drive this additional ma
chinery Manager r. U. Truman will
leave for New York next week for the
purpose OF arranging for the construc-
ton aud shipping Of the steam plant
and additional machinery required for
the enlargement of the mill to the ca
pacity above stated. This step is in
keeping with the original intention of
the Ray company. A five hundred ton
plant was part of their original pro.
gram and the present 200.ton plant at
Kelvin was erected simply with
view to determining wether or not the
Ray ore could be treated at a profit
with plant of large capacity. The
experimental run has decided the
question in the affirmative and the
company will now carry out their orig
inal intentions and make the Ray one
of Arizona's largest copper producers.

Gold dredging is proving to be a
profitable form of gold mining ia Cali
fornia as elsewhere, but extravagant
statemen are being made regarding
the possible returns. The truth is good
enough without exaggeration. A prom
inent dredger operator stated that with
his dredger ia the last year he handled
$4,000 cubic yards of material, which
averaged l5 cents per cubic yard. at a
total cost of cents per cubic yard.
This last item included every detail of
expense, including interest on the
amount invested. This, ia round
numbers. would mean the handling of
1000 cubic yards per day, at a daily net
profit of zoos, whic b is a fair average
statement of results, and in this case
truthful one. Dredging is yet an
evolutionary form of mining. Its ori. |
gin was in New Zealand, in 1869, where
the first dredging apparatus is de
scribed as having consisted of "a strong /
iron ring, technically known as a
spoon to which was recured an OK |
hide bag and a long pole. A rope was
fastened to the iron ring and secured |
to hand winch on the hank of the
river. The bucket and pole were taken
out and dropped into the stream by
means. of boat, the bucket being
pressed by the pole as deep as possible
into the wash in the bed of the river"
The bucket was then hauled ashore by !
the winch, and the contents put
through California cradle. The pro-
csss from such primative device to the
i)-OOOs gold dredger of 1900, operated
by electricity, illustrates mining and
scientific advance.-M. IL S. Press.
