Explanation

Zambia is known as the 'country of copper' due to its vast copper reserves and mining industry. Copper mining accounts for a significant portion of Zambia's export earnings and GDP. Nigeria is oil-rich, Czechoslovakia was historically industrial, and Australia has diverse mineral resources but isn't specifically known for copper.
