Previous Year Question

Kimberley–Diamond is correctly matched. Diamond discoveries in the Kimberley region of South Africa from 1867 onwards led to large-scale diamond mining. The Kimberley diamond fields played an important role in the development of South Africa's modern mining economy.

Witwatersrand–Gold is also correctly matched. The Witwatersrand goldfields were discovered in 1886, and the region became one of the most important gold-producing areas in world history. According to the South African Government, the Witwatersrand Basin continues to represent the world's largest gold resource.

Katanga–Copper is correctly matched. The Katanga sedimentary basin of the Democratic Republic of the Congo forms a major part of the Central African Copperbelt. This belt is one of the world's most important copper-producing regions, containing giant deposits such as Kolwezi and Tenke-Fungurume in the DRC.

Saar–Iron ore is not correctly matched. The Saar region has historically been famous for coal, particularly hard-coal mining. Coal mining profoundly influenced the economy and industrial development of Saarland. The major historical source of iron ore lay in the neighbouring Lorraine region; Saar coal and Lorraine iron ore together helped support the iron and steel industries of the wider industrial belt. Official Saarland records identify the region particularly with hard-coal mining.
