Peribatholitic vein-type uranium deposit, meaning that the uraniferous hydrothermal veins are formed in the rocks next to an intruding granite and not in the granite itself.
Located at Lameira das Pedrinhas, just outside Nisa village.
Part of the Nisa uranium district (about 6x2 km2).
For a very interesting study about the uraniferous province of Alto-Alentejo, and in particular about the Nisa area and the Nisa ore deposits, see Peinador Fernandes (1982).
