Torre de Moncorvo mines

The Torre de Moncorvo mines are a group of iron ore mines located in Torre de Moncorvo, Bragança in northeastern Portugal. Their deposits are among the largest in Europe, with estimated reserves of 2.56 billion tonnes of ore grading 37% iron metal.

They have been exploited at a small scale since the Iron Age by local communities. Over time, the mines developed through proto-industrial operations in the 18th and 19th centuries and became a major industrial site in the 20th century, employing up to 1,500 miners in the 1950s. Modern attempts to reactivate mining operations by Aethel Mining, were initiated in the 2020s but were halted by the Portuguese government in 2025, over lack of activity and contractual non-compliance.
