Presumably the lower mine levels were abandoned when it became uneconomical to keep them pumped out.

Exactly so! As the levels went deeper pumping, hoisting and maintaining the vertical shafts became more expensive.
Moreover the quality of the ore decreased. The final blow came when cheaper ore became available from overseas.
