Consented to Lou going after precious metal (6)
I believe the answer is:
agreed
'consented' is the definition.
(agreeing is a kind of consenting)
'lou going after precious metal' is the wordplay.
I cannot really understand how this works, but
'metal' could be 're' (Re is an example) and 're' is found within the answer.
The remaining letters 'aged' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for agreed that I've seen before include "Saw eye to eye" , "ratified" , "Acceded" , "Was consistent" , "Did concur" .)
