Remains of a possible ore hopper measuring c. 5m x 4m, c. 2.5m high. L-shaped wall remnant defines a level area c. 3m (north - south) x 1.25m (east - west) on the west side, with possible schute at higher level to the east. The surface of the level area had finer ore fragments on it, suggesting it may have been a crushing floor.
