Mine Korea for porphyry? (3)
I believe the answer is:
ore
'porphyry?' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe there's a link between them I don't understand?
'mine korea' is the wordplay.
'ORE' is hidden within the letters.
But, I am unsure how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for ore that I've seen before include "Valuable resource" , "Solid rock containing metal" , "tangle" , "Raw mineral" , "not worth a lot to Danes" .)
