Active tantalite mine in the Main Kenticha pegmatite sheet (thickness 40-100 m; exposed over 2 km). Annual production of about 120 tons of tantalum concentrate grading at 50-70% Ta2O5.
Mining is presently (Küster et al., 2009) restricted to the upper zone in the eastern and northern parts of the pegmatite.
