ites and Miocene sediments extending along the Red Sea coast. These recent exploration activities represent the first step in a longterm future plan aiming at diversifying and maximizing Egypt uranium resources, urgently required to support its national program of peaceful uses of nuclear energy needed to secure its energy resources for development projects. The upper Cretaceous phosphate deposits represent one of the promising unconventional uranium resources in Egypt. Confirmed estimates of these phosphate ore deposits amount to about 700 million tonnes. Uranium content in these deposits ranges between 50–200 ppm, with an average value 60 ppm. Although no reliable estimate of the uranium resources in Egyptian phosphate ores has been made, it is possible that the deposits contain up to 42 000 tU. 18 In Egypt, exploration and development activities were focused on four uranium prospects in southern and northern portions of the Eastern Desert and the southwest of the Sinai Peninsula. In early 2009, comprehensive geological, geophysical, and geochemical exploration works in the southern part of the Eastern Desert and Red Sea region were initiated, concentrating on potential uranium resources in new target environments. Unconventional resources, including phosphorite deposits, are also under investigation. Total expenditures in Egypt have steadily increased from USD 1.76 million in 2007 to USD 2.38 million in 2007 and 2008, respectively. Expenditures are expected to increase further to about USD 2.8 million in 2009. 19 In Niger, uranium is produced by two companies, Somaïr and Cominak, which have been operating mines in sandstone deposits since 1970 and 1978 respectively. A third company, the Société Minière de Tassa N’Taghalgue (SMTT) assigned its mining rights to Somaïr in 1996 and was subsequently dissolved. The total production capability of the two production centres in Niger is in the process of being increased from 3 800 tU in 2006 to 4 500 tU in 2009 The Government of Botswana reported exploration expenditures of USD 0.377 million in 2008 as regulations for uranium mining and milling were being developed. 79
In Malawi, the Kayelekera uranium project, located in the Karonga district of the Northern region about 600 km by road from the capital city of Lilongwe, was successfully brought into production by Paladin Energy Ltd. in 2009. Transport of the first product to Walvis Bay, Namibia, via Zambia, took place on 17 August 2009. Uranium production, by open-pit mining, with an annual production of 1270 tU, expected to be achieved in 2010, is expected to continue for some nine years. The Keyelekera uranium deposit is being mined by open pit. Operations are programmed for an approximate nineyear life, with an annual production of 1270 tU. Total uranium production is expected to amount around 11500 tU. Processing of marginal ores at the end of mine life is expected to add an additional 3– 4 years to the mine life. 20 Infill drilling amounting to 9 955 m was conducted in 2008 on the Kayelekera deposit, where open pit mining began in April 2009, but expenditures were not reported In Namibia, extensive exploration activity takes place, mainly in the Namib Desert. Two major types of deposits have been targeted; the intrusive type, associated with Alaskite, as at Rössing, and the surficial, calcrete type, as at Langer Heinrich. Substantial growth in uranium exploration has occurred in Erongo area of westcentral Namibia, focusing mainly on previously-known deposits with considerable historical data. Over 60 exploration licenses had been issued up until early 2007, when a moratorium on new licenses was imposed by the Namibian government. Major drilling programmes were conducted in support of proposed expansions of the Rössing and Langer Heinrich mines, ongoing development of the Trekkopje mine and continuing evaluation of several deposits for possible mine development, including Husab, Etango, Marenica, Rössing South and Omahola deposits. However, the Government of Namibia reported expenditure and drilling activity details for Rössing only. The uranium resources of Namibia, including both identified and undiscovered, occur in a number of geological environments and consequently are hosted in several deposit types. The Identified Resources are mainly associated with intrusive and surficial deposits. In addition to the Identified Resources in the Rössing, Rössing 80
