Anticipate charge protecting valuable sources (7)
I believe the answer is:
foresee
'anticipate' is the definition.
(I know that anticipate can be written as foresee)
'charge protecting valuable sources' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge).
'protecting' is an insertion indicator (inserted letters are held or protected).
'valuable sources' becomes 'ores' (I have seen 'Sources of metal ' mean 'ores' so perhaps 'sources' could also mean 'ores'. I am not sure about the 'valuable' bit.).
'fee' placed around 'ores' is 'FORESEE'.
Can you help me to learn more?
(Other definitions for foresee that I've seen before include "Prognosticate" , "divine" , "Predict" , "Realise or be aware of in advance" , "Imagine" .)
