In the Segura mining area tin and tungsten were explored from 1942 to 1953.
Granitic pegmatite veins with cassiterite and lepidolite, hydrothermal Sn-​W quartz veins and Ba-​Pb-​Zn quartz veins intruded the Cambrian schist-​metagraywacke complex and Hercynian granites.

The Segura mining area was constituted by 12 tungsten, tin, lead (and barium) concessions. The mineralizations were explored between 1942 and 1953 by the Segura Mining Company, Ltd. The quartz veins mineralized in Sn-W produced about 100 tons of concentrates with 60% and 12 tons of cassiterite concentrates with 50% wolframite, while the Ba-Pb-mineralized quartz veins produced 525 tons of barite and 211 tons of galena.
