Gold-digger writing about power, starting to cite Rocky Hill (10)
I believe the answer is:
prospector
'gold-digger' is the definition.
(I've seen this before)
'writing about power starting to cite rocky hill' is the wordplay.
'writing' becomes 'prose' (prose is ordinary writing as opposed to poetry).
'about' indicates putting letters inside.
'power' becomes 'p' (symbol in physics).
'starting to' suggests taking the first letters.
'rocky hill' becomes 'tor' (I've seen this before).
The first letter of 'cite' is 'c'.
'prose' placed around 'p' is 'prospe'.
'prospe'+'c'+'tor'='PROSPECTOR'
(Other definitions for prospector that I've seen before include "Gold-digger" , "Clementine's father, perhaps?" , "Searcher for minerals" , "One searching for valuable minerals" , "Searcher after valuable ores" .)
