Mining industry of Lesotho : ウィキペディア英語版 | Mining industry of Lesotho The mining industry of Lesotho is mostly concentrated on diamond mining and as such the mining sector in the country has not played any significant role in furthering its economy. Apart from diamonds, the country's main mineral resources have been identified as base metals, clays, dimension stone, sand and gravel, and uranium. The lack of initiative to extract other minerals commercially is mainly attributed to the inadequacy of infrastructure and finances, and the high rate of HIV/AIDS infected people. Between 2000 and 2011, the percentage of GDP contributed by diamond mining to Lesothos economy rose from "virtually zero" to about 4%. ==History== The mining of diamonds started in the country only in the later part of the 1950s. Mining licenses for diamonds from Kao and Liqhobong pipes were operated for a short period from 1959 till Lesotho’s independence. Following the independence of the country, the mines were closed due to poor production.〔 In Lesotho's mining history, skilled artisans (known as Basotho diggers) have been extracting diamonds to a large extent under licenses issued in 1961 for the Letseng diamond mine, as well as Kolo, Nqechane and Hololo areas, with a positive impact to the economy of the country. Extraction from the Letšeng diamond pipe, which started in 1968, was not productive and closed in the 1970s. However, these mines were restarted in 2000 and have proved to be productive.〔
