The deposits of this mine lie in or along the faults as replacement and impregnation. So, generally speaking, it is very difficult to distinguish the boundaries between ore bodies and country rocks. Moreover, the both sides of ore bodies are very brittle due to shearing stress and alteration of rock. Therefore, timbering and filling with waste rock are necessary in stoping. Until recently the over land flatback filled stoping had been used, but the slushers has been adopted in filled stopes, since June 1956, to raise the efficiency of stoping. The results of slushers in filled stopes have been a great success.
