RICH COPPER FIELDS.
The Great Mineral Discovery in Ari-
zona-High ASSAY Of Ore.


zona-tfigh ASSAY Of Ore.
The latest mineral discovery Of
Importance in the southwest is in
northern Arizona, north Of Williams,
town on the line Of the Atlantic q
Pacific railway, and not far distant
at any point form the Grand Canyon
Of the Colorado. The mineral is cop
per, and is more widely diffused than
in any other of the mineral districts
Of Arizona. For the distance OF 10
miles south Of the canyon the lime
rocks of the country are permeated
with copper ore in carbonate form,
and several hundred locations now
cover almost every cropping that
shows the presence of copper or its
attendant IRON
For years it has been known that
2 great deposits Of sulphuritic copper
ores lie far down in the mile or more
depths of the Grand canyon. The ores
from the Cameron mine, particularly
have sampled to ~ per cent Of metal.
Gold and lead, asbestos, and even
coal have been exposed in the great
sbutteresses Of this grand terrestrial
%eanal; but little was it known that
mingled with the limestone of the
southern rim lay wonderful body Of
copper ore. The first discovery Of
Importance was October, about As
miles north of Williams by Ferdin-
and and William Nellis. Soon after
the winter SHOWS fell deeply, but the
prospectors were not deferred by the
cold, and the traveller through the
pine and cedar forests Of the region
now rarely finds himself distant
from a monument marking the bor-
ders Of a mining claim.
Little more than the statutory as
sessment and location work has been
done on any of the claims, and the
deepest workings are yet only about
40 feet. What might be called the
"pay streak" Of the district lies inn
mediately north of Williams, at a
distance Of about AS miles, thence
continuing northward, three miles
wide, to the Grand canyon rim, Is
miles distant.
Throughout this ''pay streak" the
!. ores are constant in values, quality
and character. As before stated, the
ores are mainly carbonate in the
malachite and azurite forms, with
black and yellow oxides and here and
there trace of copper pyrite. They
Ore found only where the limestone
has been disturbed through volcanic
faction, and never where the stratifi-
cation has remained regular. They
are invariably closely associated with
the limestone, and run high in iron,
forming a combination that carries
its own fux to the smelter. The per-
centages of copper run high. have
, seen many large specimens of the
Z surface rock that assay to so per
cent, and have good authority for the
statement that the ore on the dumps
Of the main claims will exceed 20 per
cent. 1t might be instanced that the
ores of the Lake Superior district are
profitable when they run even as low
as 16 pounds of copper to the ten.
The ore lies horizontally, or nearly
so, and its depth has not been as
certained. Perhaps an indication of
it all might be found in consideration
of the fact that the carboniferous
limestone that caps the region is at
no place on the canyon less than 800
feet in depth. 1t is fair to presume
that the copper ,permeates this stra-
tum at least, and the general i'm
preston among the miners is that
the district is destined to have the
deepest workings Of any in the west.
The copper has been vomited from
the depths of the earth, and has
found Judgment in the riven lime
and sandstone rocks, spreading out,
branch-like, from the clefts of the
principal eruptions. Then nature,
with her iron, lime and oxygen,
leached the sulphur away. Perhaps
this would account for the presence
intheimmediateyicinity of great beds
of sulphate Of lime, gypsum.-Den-
