The Rasas and Cobalto Mines, in Torre e Vila Mou (municipality of Viana do Castelo), are part of a small group of historical mining operations in the Lima Valley. Here is a summary of what is known:
- They consist of a group of old mines, not a single operation.
- They include concessions called “Rasas” and “Cobalto,” mainly registered in the 1950s.
- The main exploitation was linked to tin (Sn), despite the name “cobalto.”

Coordinates:
More precise approximation (based on nearby toponyms)
Using “Lugar das Rasas / Rua da Rasas” in Vila Mou:
≈ 41.7345, -8.6998
This is likely very close to the mining area, since the place name Rasas is directly tied to the mine workings.
