Candidate to look for gold (8)
I believe the answer is:
prospect
This clue could be a double definition.
'candidate' is the first definition.
(I know that candidate can be written as prospect)
'look for gold' is the second definition.
'prospect' can be an answer for 'look' (thesaurus). I am not sure about the 'for gold' bit.
'to' is the link.
Can you help me to learn more?
(Other definitions for prospect that I've seen before include "Gray distantly associated with Eton College" , "'Outlook, vista (8)'" , "Search for mineral deposits - possibility" , "Expectation" , "View - likely future" .)
