Speaker finds gold on a hill (6)
I believe the answer is:
orator
'speaker' is the definition.
(I know that orator is a type of speaker)
'gold on a hill' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'hill' becomes 'tor' (tor is a kind of hill).
'or'+'a'+'tor'='ORATOR'
'finds' is the link.
(Other definitions for orator that I've seen before include "He lectures" , "A Rhetorical talker or speech-maker" , "He addresses" , "I declaim" , "Eloquent public speaker" .)
