Gold and special metal found in Texas (6)
I believe the answer is:
austin
'in texas' is the definition.
('Austin' is part of 'texas')
'gold and special metal' is the wordplay.
'gold' becomes 'au' ('Au' can be a synonym of 'gold').
'and' says to put letters next to each other.
'special' becomes 's' (common abbreviation as in Special Air Service**).
'metal' becomes 'tin' (tin is a kind of metal).
'au'+'s'+'tin'='AUSTIN'
'found' is the link.
(Other definitions for austin that I've seen before include "The capital of Texas (6)" , "Engineer" , "Texan city" , "State capital of Texas" , "Capital city of Texas" .)
