Predict charge to cover metal sources (7)
I believe the answer is:
foresee
'predict' is the definition.
(I've seen this before)
'charge to cover metal sources' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge).
'to cover' is an insertion indicator.
'metal sources' becomes 'ores' (I've seen this in another clue).
'fee' enclosing 'ores' is 'FORESEE'.
(Other definitions for foresee that I've seen before include "divine" , "Prognosticate" , "Anticipate" , "Predict" , "Be aware of beforehand" .)
