No truer test of the richness of Arizona mines can be found than in the steadily increasing volume of bullion which is finding its way out of the country. This yield has more than doubled each year since the Southern Pacific railroad entered the mineral fields of Southern Arizona. In 1880, according to the report of Wells, Fargo & Co., the total output was near $4,000,000. This did not include the raw ores, concentrations, and placer gold shipped through other sources. The yield for 1881, reckoning on the basis of the present monthly production, will be about $9,000,000. This estimate does not include the copper product, which will reach 4,000 tons, worth over $1,500,000. Add to this the ores and concentrations and placer gold, which finds its way out of the country, and the entire bullion yield for the present year will be over $12,000,000, thus placing Arizona third on the list of the bullion-producing States and Territories.
This is a good showing for a country whose total shipment six years ago amounted to only $109,083! With such a rapid increase in the output of treasure since the building of one railroad, what may we not look for a year or two hence, when Northern Arizona will be opened by another transcontinental line, and the leading camps north and south will be tapped by branches? It is not too much to expect that the Territory, now third on the list, will take the first place in the production of the precious metals. No country has so extensive a mineral field, possesses so many natural advantages, or can show ores of such wonderful richness, lying almost at the very surface. Some of the most eminent geologists and mineralogists long ago predicted that the region now embraced within the Territory would yet prove to be the richest mining country on the globe. The soundness of their judgment is at last being practically demonstrated, and it is evident that Arizona is soon to become the great bullion-producer of the world. No mining country can show such a return for the amount of capital invested; none presents to the man of enterprise more guaranties for success, and none has so bright a future.
