Valuable metal obtained after mine is stripped (5)
I believe the answer is:
ingot
'valuable metal' is the definition.
'ingot' can be an answer for 'metal' (I've seen this before). I'm not certain of the 'valuable' bit.
'obtained after mine is stripped' is the wordplay.
'obtained' becomes 'got' ('get' can be a synonym of 'obtain').
'after' says to put letters next to each other.
'is stripped' indicates the central letters (outside letters removed).
The central letters of 'mine' are 'in'.
'got' put after 'in' is 'INGOT'.
Can you help me to learn more?
(Other definitions for ingot that I've seen before include "Cast metal obtained from a mould" , "Mass of cast metal" , "Mass of unwrought gold, for instance" , "Unwrought metal cast in a mould" , "valuable block" .)
