Mining at Kundana has Proven Suitable for Narrow Vein Mining Operations The prime method of mining at the Kundana gold mine is by long hole bench stoping following which it is backfilled The usual length of the long hole being between 12 to 15 metres if backfilled with waste rock The height is normally between 10 and 15 metres This is sufficient to gain access to the ore
