Apparatus suitable for mining cobalt rich crust deposits existing on or near the surfaces of seamounts on the bottom of the sea uses a continuous line bucket method with a mining ship which mounts said device thereon. The device is equipped at optimal locations with an endless rope, a driving mechanism, a large number of dredge buckets, a guide wheel on paying out side, a guide wheel on pulling up side and devices for maneuvering the ship. The endless rope is paid out from the ship with the large number of dredge buckets attached thereon to dredge off and mine the crusts while the mining ship is steered ahead. The method is characterized in that as the rope line on the paying out side constantly traces an arc while that on the pulling up side traces substantially a straight line, they can be kept apart from each other, and that a strong tension can be applied on the ship from the pulling up side to allow the ship to overcome the resistance and to turn smoothly by positioning a guide wheel on the pulling up side at an optimal location near the center of gravity of the ship.
