In remote times, initially the Phoenicians, later and chiefly the Romans, exploited gold in this mining district. At the end of the XIX century, this belt was extensively mined for antimony; and, as a sub-product, gold contained in quartz veins.

The Montalto mine is an abandoned antimony and gold mine. It was mined after 1865 (mining concession no. 25, registration date 28-10-1865).
