San Finx Mine W-Sn

San Finx is a historical underground mine located in Lousame, 30 km outside of Santiago de Compostela, in Galicia (NW Spain). The mine was opened in 1884, being operated by different companies until 1990. In 2009, the mine was reopened by Incremento Grupo Inversor, but due to the lack of financial resources the operation ended in early 2013. Valoriza Minería acquired the mine in 2015 through its subsidiary Tungsten San Finx and has work intensively to reopen it since then. The mine is part of the T&T Cluster that Valoriza Minería is developing.

Challenges

Entrada mina

One of the biggest challenges that Tungsten San Finx is facing is to adapt the historic mine to the 21st century and to respect all sensibilities. Because environment and sustainability are two of Valoriza Minería´s highest priorities, the mine is being adapted to more efficient ways of extracting and benefiting the mineral. Also, all approved permits are being updated to the new legislation.

At the moment, Tungsten San Finx is working to achieve the permission to dewater the deepest plants of the underground mine.
