The copper era. (Clifton, Graham County, Ariz.) 1899-1911, 1908-09-10

repute. We have secured Il reduc-
tion of 20 cents per ton on the freight
on all our ore, and we have granted
on remunerative terms running rights
for three years over portion of the
New England s, Clifton Tramway to
the Clifton Northern Railroad, pro-
vided such railroad does not interfere
with the operations of our own.
We have a separate charter for
our tramway, which is now owned by
the San Francisco River Railroad
/ Company, and this railroad, in addi-
ton TO handling our ores, has become
an independent and valuable asset,
all the stock being owned by the min
ing company.
Well, gentlemen, you will see from
these reports of Messrs. Moses and
Perry, which have just read, that
the course of the company is very
plain one: In the first place, refer
ring to the Antietam, we do not
know as yet with certainty whether
this is going to be a large, low grade
proposition, or whether it is going to
be a combination of high grade and
| low grade ores, and until we sink to
the 500-foot level and Cross-cut and
carry out the development work
which has been suggested, which will
take about nine months, we are not
justified in forming final opinion on
the real extent, value, quality and
nature of the ore bodies in this prop
erty, and the most economical and
profitable way to deal with them.
Assuming that for the moment it
will turn out low-grade ore with a
vein from 40 to 70 feet wide of per
cent. copper, we may have to concen-
trate this ore, and the question as to
whether we should concentrate this
ore at the same concentration as we
propose to erect for the Copper King
ore is, of course, an important one,
and a great many matters are to be
considered, for example the Copper
King ore runs about 10 per cent. in
SILICA and the balance of its contents
are gold, silver, copper and iron,
believe. The Antietam ore is about
20 per cent. iron, about - per cent.
sulphur, and d small amount relative
ly, SILICA with copper contents, vary
ing from two to ten per cent. and also
with gold and silver. The Antietam
ore is very soft, the Copper King ore
very hard. Now d mill that will sue
cessfully concentrate and give the
best results for the Copper King ore
might be and probably would not be
altogether suitable for the Antietam
or soft ore. Different classes of ore
frequently require different machin-
cry for concentrating, in order to get
the best results. You install your
concentration to suit the ore proposed
to be treated. Que kind of ore will.
perhaps, only concentrate four tons
into one, while another will concen-
trate ten tons into one. 1t is most
important to use every possible care
to get the concentration most suitable
for the ore you have to concentrate,
as every one, two, three, four or five
Der cent. extra that you save of the
metallic contents is a matter of great
Importance to you. For instance, if
you made a mistake in selecting the
most suitable machinery for your
mill, and only saved - per cent. of
the ore, instead of so or 50 per cent,
you can see how quickly that would
run into money.
Again, it costs us altogether about
sec per ton TO bring Antietam ore tu
the Shannon smelter, and so far as
can see, it will continue TO cost us
that amount of money. Now, SOC per
ton on a large body of low grade ore
is good profit. In other words, if
you had half million tons of low
grade ore, SOC freight would, as you
see, represent S4OO, 900, which might
be saved possibly by erecting your
concentration at the mine.
1t was suggested by Mr.. Veitch that
we could bring the Antietam ore
through one of the tunnels of the
Copper King mines by tunneling and
by ;erial trans, and bring it to tie
same concentration as the Copper
King ore was being concentrated at,
assuming that was a proper cOncer-
traitor for the Antietam ore.
Again, Mr.. Forbes suggested that
it was so high in sulphur and iron il
might be sent to the smelter direct
without concentration, or we nigh
install blast furnace at the mine and
ship the matte to the smelter.
On the whole, therefore, l have felt
that these questions could well be
left for consideration until we have
done more development work on the
Antietam mine, and we would there
fore be better able to Judge what we
shall actually need in the future.
Such considerations do not at al
warrant us in longer delaying install
ing a concentrating plant suitable
for the Copper King ores and sufli
cient to handle 100 tons of ore pei
day. We have already ordered the
drill plant, and it should be installed
by the beginning of October, and il
will cost 81, 80 complete. and its cost
will be saved when 7,T50 tons of ore
