Korean mineral? (3)
I believe the answer is:
ore
'mineral?' is the definition.
(ore is a kind of mineral)
'korean' is the wordplay.
'ORE' is hidden in amongst the letters.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for ore that I've seen before include "Naturally occurring mineral" , "Mineral containing valuable metal" , "Metal-bearing rock or mineral" , "Mineral-bearing material" , "Solid rock containing metal" .)
