One searching for gold has wide view on most of raw material (10)
I believe the answer is:
prospector
'one searching for gold has wide' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'view on most of raw material' is the wordplay.
'view' becomes 'prospect' ('prospect' can be a synonym of 'view'**).
'on' is a charade indicator (letters next to each other).
'most of' means to remove the last letter.
'raw material' becomes 'ore' (I've seen this before).
'ore' with its last letter removed is 'or'.
'prospect'+'or'='PROSPECTOR'
Can you help me to learn more?
(Other definitions for prospector that I've seen before include "Clementine's father, perhaps?" , "Searcher for minerals" , "One searching for valuable minerals" , "Gold-digger" , "Searcher after valuable ores" .)
