In a Bronze or Iron Age settlement on Szent Vid Hill, copper and antimony ores (which it is thought were mined on what is now the Austrian side of the valley), were smelted and alloyed. Cretaceous metamorphic rocks (mainly chlorite schists and serpentinite) occur in the region of Bozsok, Felsőcsatár, and Vaskeresztes. The mineral assemblage of quartz-albite veins present in the chlorite schists consists of major quartz, chlorite and albite and smaller amounts of actinolite, epidote and pyrite, together with some chalcopyrite and malachite. In chlorite schists on Szőlő Hill, near Vaskeresztes and close by some beautiful octahedra of magnetite have been found (Fig. 79).

In the 1950's, an extensive talc deposit was discovered south of Felsőcsatár and a mine was opened which is still working today. The talc, produced by a small staff when suitably ground, is used
