“There are undoubted proofs of the exist-
ence of exceedingly valuable copper mines in
this Territory at various points convenient to
the navigable waters of the Colorado and its
tributaries. Mr. Pompelly, a scientific geolo-
gist and mineralogist, who subsequently was
appointed mineralogist to the Japanese Gov-
ernment, made an extended examination of
the mineral resources of Arizona, and in the
published report of his observations he refers
particularly to the extraordinary richness and
extent of the copper resources of the Terri-
tory. Other parties, who have travelled ex-
tensively through it since Mr. Pompelly, fully
corroborate all that gentleman reported on
this subject. Important mines have been dis-
covered, and districts organized at many
points in the Territory, among which are the
Irataba district, about twenty-five miles south-
west from Fort Mohave; the Freeman district,
about sixty miles south of Williams’ Fork;
the Chimewawa district, on the west bank of
the Colorado, nearly opposite La Paz; the
Salaza district, about thirty-five miles north-
east of La Paz, and the Castle Dome district,
about thirty miles north of the Gila. The for-
mations in which the copper is found in this
Territory are altogether different from those
in which it is found in Oregon and California.
The ores themselves are also quite distinct,
and far more valuable than those found in
those States.”

Mr. Brown, speaking of the copper dis-
trict in the valley of the Williams river, says:
“The Mineral Hill Company have run a tun-
nel on their mine for the length of 350 feet,
out of which, while cutting, they took nearly
1000 tons of ore of an average of 30 per cent.,
the whole work from the surface being in a

 

body of ore. The ore in none of the mines in
the district is found in a regular lode, as in
the mines in California, but the whole country
appears to be formed of iron and copper.”
The copper exists in the form of heavy masses
of ore embedded in large quantities of powdery
oxide of iron. Sometimes, when these heavy
masses are removed, this dry powder comes
rushing down to the amount of hundreds of
tons. Some of the copper ore found in this
locality is quite rich in gold.

When the rich and exhaustless coal mines
of the Raton Mountain shall be connected
with these Arizona mines by the Union Pacifie
Railway, then, and not before, will the bound-
less wealth of that Territory be made avail-
able.
