RC 400
Truck-mounted reverse-circulation exploration drill.
Sample-recovery exploration rig that uses compressed air through hollow inner tubes to deliver continuous rock-cuttings to surface. Mounted on an 8×4 truck chassis for road moves between targets, it drills 128–150 mm holes to 350 m vertical at angles 45°–90°. The crawler-mounted DRC 350 carries the same drilling equipment on tracks.
