The mine was reopened in 1896 and worked by a succession of owners for witherite and baryte until 1919. Though largely inactive since, the mine was held under lease until 1963 when it was finally abandoned.Sphalerite and galena occur in very minor amounts, particularly in Cu-rich footwall mineral zones and as late, cross-cutting veins in association with late shear zones and faults (Table 4.3). Sphalerite and galena also occur as interstitial grains in massive sulfide and adjacent to silicate inclusions. Galena Química e Farmacêutica LTDA Pedro Stancato, 860 Campinas - SP.
