Prospector's place (4)
I believe the answer is:
mine
'prospector's place' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mine that I've seen before include "Donnybrook" , "Source of ore belongs to me" , "Excavation in the earth for digging coal etc" , "Pit; source" , "Source of wealth" .)
