The Moncorvo iron mines were the object of primitive mining from the Iron Age until the end of the Eighteenth century. The first experience in proto-industrial mining took place in the 1790s; in the 1870’s the interest in the Moncorvo mining concessions was renewed and as many as 35 concessions were registered at a certain point. In 1897 most of the concessions were acquired by the Company "Syndicat Franco-Iberique" that initiates "systematic and methodical prospecting works with 1396 chemical analyses."

Between 1930 and 1934 were opened galleries in Mua, with the extraction of 15,279 tons of ore, as per the records in the Boletim de Minas [Mines Bulletin]. The prospecting and extraction works of the “Companhia Mineira de Moncorvo” continued until 1942. After the 2nd World War the Portuguese Government took possession of the concessions of that German company and, in 1957, the management of company was transferred to "Exploration & Bergbau", part of the Thyssen group, under the name of Minacorvo, Lda.


That year was constructed the pilot treatment plant and, in 1976, Minacorvo was dissolved and its concessions integrated in Ferrominas SARL, later Ferrominas EP, ending with the creation of EDM EP in 1986. 

1,796,535 tons of Moncorvo iron ore were exported between 1951 and 1976.
