| Abstract: | The Kalahari Cu-Au metallogenic zone is world-famous Cu-Au ore belt where copper ore reserve makes up about 10% of the total in the world. It extends for about 1500 km with a width of 15 km from Nan-tibia through Botswana to Zambia and for about 500 km with a width of about 10 km within the boundaries of Botswana. A western mining company discovered several Cu ore beds in the depth in the Chobe region in 1982. Astra Exploration and Mining Company （Pty） Ltd made airborne magnetic and gravity survey in the Chobe region in 1995. |
