Out of a ton of ore from the Stonewall Jackson Mine, adjoining the
General Lee, in the Globe District, (Arizona) there was extracted
October 25th, by the Pacific Refinery, San Francisco, ten bars of
silver valued at $3,800, which is over 36 per cent. metallic copper.
At Clinton, Arizona, the great copper mining center, the Longfellow
Company have two furnaces running, and turn out as high as 10,000
pounds of pig copper daily. The furnaces used are Bennett’s patent.
Arizona has, without doubt, the richest and most extensive copper mines
in the world. This metal is all shipped east by way of El Moro.

Charles P. Stanton, geologist, writes to the Prescott “Miner,” under
date of Nov. 9th, 1877, as follows: The great carboniferous basin of
Arizona--and in all probability of the world--exists within 140 miles
of Prescott. This immense coal deposit makes its first appearance
in Southwestern Colorado and Northwestern New Mexico; but its great
nucleus extends from Tierra Ausarilla, in Rio Arriba, New Mexico, to
the Colorado River, a distance of 276 miles, and from the San Juan
River, a distance of 138 miles. This immense area of 38,088 square
miles is one continuous mass of coal. It lies between the parallels of
100 and 112 west longitude, and 35 and 37 north latitude, and all in
Yavapai County.

Note.--A vein of ore one inch thick, six feet long, and six feet high,
will measure three cubic feet; two inches, six cubic feet, and so on
in proportion, allowing three cubic feet for every inch of ore in the
lode, six feet high and six feet long.
