The world's economic resources of tin total approximately seven million tonnes, of which Australia has approximately 1.3%. Eastern Asian countries, including China (27%), Malaysia (15%), Thailand (12%) and Indonesia (10%) possess the majority of the world's economic tin resources. Other countries with large tin resources include Brazil (16%), Bolivia (6%), Peru (4%) and Russia (4%).

More than 85% of Australia's economic tin resources are located at the Renison Bell deposit in Tasmania, a primary carbonate replacement deposit which supports one of the world's largest underground tin mines. Australia's next most important mine is at Greenbushes in Western Australia, where tin is recovered along with tantalite (a tantalum mineral) from a weathered primary deposit.
