Lucara Botswana’s Karowe diamond mine is located near the village of Letlhakane in the eastern Kalahari Basin region of Botswana. Currently an open-pit mine, it is expected to cease open-pit activities by 2026 after which it will continue mining underground, extending its operational life to around 2040. More than 1 000 metres above sea level, the mine operates in a region where temperatures average 35°C and water is scarce; so much so that the Government of Botswana has legislated mandatory water-saving requirements for the industry.
