Abstract: An uncovered storage facility for stockpiling bulk materials for establishing stockpiles (38) of predetermined geometry. The facility comprises a base (40) having facing retaining walls (42, 44) which are provided by structural berms (46, 48). The berms (46, 48) are for supporting a stacker machine (10) on one side of a stockpile (38) and a reclaimer machine (22) on the other side of the stockpile (38). A high berm (46) supports a stacker machine (10) and a low berm supports a reclaimer (22). The berms (46, 48) provide for more efficient access to a stockpile (38) by a stacker (10) and a reclaimer (22) and a predetermined stockpile geometry which allows increased reclaim efficiency compared to a stockpile of traditional geometry.
