The whole ore body is mined with no overburden being put back into the void during the extraction operation. Some placer deposits are amenable to strip mining or dredging operations. In strip mining the overburden is removed and deposited in the hole left from the excavation of the previous strip or panel and the ore can be simply dug out.
