Abstract

The Kasuga mine is located 4 km west of Makurazaki city on the southern tip of Satsuma peninsula, Kagoshima Prefecture. Among several silica bodies scattered in the Kasuga area, Kasuga Honkotai (the main orebody) is the major gold producer; it has a cumulative gold production to date of approximately 9.3 tons (t) of gold.

The silica body of the main orebody extends 500 m east- west and 100 m north-south with a thickness of about 80 m (Figs. 1 and 2). The average gold content of the silica body ranges from 2 to 3 ppm, and relatively high-grade ore grades 5 to 10 ppm along fissures or brecciated zones (Urashima et al., 1987).
