When the impairment of the stock of silver coins by export to India and the surrounding countries necessitated larger and regular supplies of the metal, Rome applied herself to the exploitation of her Spanish mines with a vigour as great as it was pitiless. The native races and their erstwhile Carthaginian masters worked side by side, and their ranks were subsequently swelled by condemned criminals from Italy, and in later times even by legionary soldiers. Jacob tells us that “the silver procured by the Romans by these operations must have cost more than its current worth; and, according to Polybius, the 40,000 workmen who were constantly employed in the silver mines at New Carthage in Spain produced only 25,000 drachmas (valued at under £1,000) per diem—a sum that could scarcely have purchased more than sufficient to keep alive the miserable beings who were immolated in them. Another reason why these mines were worked at a loss at this time, if indeed they were, is supplied by Del Mar, who points out that “when these mines were worked by the Romans there already existed in their own markets a mass of the precious metals that had been obtained at a cost which, reckoned in blood and cruelty, was immeasurable; but which in mere pecuniary outlay of labour, in killing and sacking, was as nothing. It was against the competition of this mass of metals, which pecuniarily cost nothing, that the mine owners had to measure their products in the Roman market; and it is to be hardly wondered at that they found the industry unprofitable. The Spaniards subsequently had the same experience in America, and the Californians and Australians are repeating it at the present time.

The Romans also worked for gold the sands of the Guadalquiver, Darro and Duero rivers, but with what results is not known. They also mined for copper on a large scale, with, it is evident, the most gratifying success. The mechanical resources at their command were limited, and there seems no doubt that many rich mines were abandoned for want of knowledge and the proper appliances with which to treat the ores. In one instance, that of the Escurial Mines at Escurial, a huge lode carrying rich copper was broken by a fault, and the Romans made no effort to pick up the lode again. The present English owners penetrated the fault, and found the lode of the original dimensions on the other side.
During the eight hundred years that Spain was under Arab domination, the mines of Sardinia are believed to have been worked by the conquerors, and they prosecuted their explorations for the precious metals on the main land with some vigour. Yeats, in his History of Commerce, tells us that in the eighth century the old silver mines, thought by the Romans to be exhausted, were made to yield afresh by skilful working; and the Spanish mines then furnished to the world the chief supplies of precious metals. The Arabs exported quicksilver to Constantinople, and it is possible that they extended the industry by opening up new mines. Spain is so full of metals that, after being explored for centuries, new mines are constantly being discovered; and perhaps the richest of all the silver mines—the Hiendelæncina—was opened up in 1843. But what the Arabs did in the way of discovery we have no means of ascertaining. They are believed by Jacob to have re-opened the Roman silver mines in the present French division of the Pyrenees, and to have worked the gold mines at Lares, the silver mine of Zalamea in Andalusia, and that of Constantina, near Cazalla. The hills of Jaen, upon which they principally concentrated their exertions, are pierced with over five thousand shallow pits, which are estimated to have been the work of five centuries. Even the approximate amount of the precious metals obtained as the result of Arab mining in Spain is a matter of the merest conjecture.
It is curious to note that when Spain was at the zenith of her greatness the wealth in which she abounded was not the result of the exploitation of her own vast stores of precious metals, but the fruits of conquest, bloodshed, and cruelties, similar to those which she had herself suffered at the hands successively of the Phœnicians, the Carthaginians, the Romans, and the Arabs. She had seen each succeeding nation of her despoilers crumble into decay, but she failed to learn the lesson that their disastrous endings had for her.
In her turn Spain crushed Mexico and Peru, and grew rich and powerful by tribute and plunder to the neglect of her own resources and her ultimate temporary ruin and submersion among the nations of Europe. Her own metallic hoards were passed over—the treasure for which Carthage, and Rome, and Morroco had fought and bled was neglected; while the methods of the Roman and the Carthaginian conquerors were being practised upon the people of the New World. The result is, that while Spain is to-day recognised as the richest mineral country in Europe, her mineral assets are in a more backward state of development than those of any other European country.

In the production of copper ore, lead, and quicksilver Spain heads the list; she is second only to Austria-Hungary in the production of salt and silver; her tin mines are at present almost untouched; while among the less important minerals distributed over the Peninsula are manganese, antimony, cobalt, soda sulphate, sulphate of barium (barytes), phosphorite, alum, magnesia sulphate, sulphur, kaolin, lignite. Gold is also found there in payable quantities; coal and cement of good quality and in enormous deposits are present in the province of Lerida; while the richness and extent of her iron resources in the districts round Santander and Bilbao have long been recognised. With all this vast mineral wealth within her boundaries, Spain should be one of the richest, rather than one of the poorest of European countries. The natural conditions are all favourable to the development of the industry. Labour is cheap and abundant, transport facilities are mostly good, and the mines are within easy reach of all the important markets of the world. The working of the mineral resources is carried on under generous and encouraging State regulations. For this purpose the whole kingdom is divided into three sections, and each of these into four districts. Each section is under the charge of an inspector-general of the first class, and each of the districts under an inspector of the second class. There are no harassing restrictions to hamper the energies of the mine owner, while the climatic conditions render it possible to work the majority of the properties all the whole year round.
