Other ancient alloys include pewter, brass and pig iron. In the modern age, steel can be created in many
Sundown Tin and Copper Mine the highly volatile base metal mines industry. The combination of metals produced at the mine increases the potential of the site to contribute worthwhile research results. Sundown Tin and Copper Mine Sundown Tin and Copper Mine is a heritage-listed mine at Little Sundown Creek, Stanthorpe, Southern Downs Region, Queensland, Australia. It was built from to 1920s. It was added to the Queensland Heritage Register on 28 July 2000.
