One going for the gold, perhaps (5)
I believe the answer is:
miner
'one going for the gold perhaps' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for miner that I've seen before include "Bevin boy" , "Person who works underground" , "Coal worker" , "it's the pits, for me" , "Underground labourer" .)
