Mining Methods at Kimberley, J.T. Fuller, Engineering and Mining Journal, Vol. 94, No. 19, pp. 887-891, and No. 20, pp. 943-948 (1912). This article describes the mining methods used at Kimberley. Open-pit mining is used for the upper 300 to 500 feet of the kimberlite pipe, and vertical shafts and horizontal adits are used to reach deeper levels. The majority of the diamond mines in Botswana were discovered as a direct consequence of soil sampling for indicator minerals such as garnet and picroilmenite. Over the past 60nbsp;years the application of soil sampling for indicator minerals as a primary exploration tool has declined while aeromagnetic surveys have increased in popularity. The rate of kimberlite discovery in Botswana has
