Khartoum – The mining industry of Sudan was mostly driven by extraction fuel minerals, with petroleum accounting for a substantial contribution to the country’s economy, until the autonomous region of Southern Sudan became an independent country in July 2011. Gold, iron ore, and base metals are mined in the Hassai Gold Mine. Chromite is another important mineral extracted from the Ingessana Hills. Other minerals extracted are gypsum, salt, and cement. Phosphate is found in Mount Kuoun and Mount Lauro in eastern Nuba. Reserves of zinc, lead, aluminium, cobalt, nickel in the form of block sulfides, and uranium are also established. Large reserves of iron ore have been established.
Ancient historical records indicate that gold and iron mining in the country existed under the kingdom of Meroë and also during the reign of the kingdom of Nubia, the Pharaonic era, during the Roman period. The name ‘Neb’ in the Nubian language means “gold” and is attributed to the Nuba region. It was also called the “country of metal” by the British.
Production from the mining sector accounts for about 4% of gross domestic product (GDP). Mineral extraction reported by the Government of Sudan include gold, chromium, gypsum, salt, and cement. In 2012, the production of crude petroleum dropped to about 37.7 million barrels (Mbbl) from a high of 106. Mbbl in 2011 and 168.7 Mbbl in 2010. Production of gypsum, feldspar, salt, gold, and cement have increased since 2012. Approximately 250,000 artisanal miners work in gold production.
In the open pit Hassai Gold Mine, which has been under operation since 1993, gold production from 18 open pits was to the extent of 2.3 million ounces (Moz). The established reserve at this mine in the Proterozoic-aged Ariab greenstone belt is 14.09 million tons.
The Minerals Development Act of 2007 and its regulations are in force. The Investment Promotion Law of 1999 and its amendments define the benefits that are available to the private companies to invest in the mining sector; agreements drawn cover both the exploration and mining phases. In the first instance, an Exploration Prospecting License is issued. Following a successful exploration of specific mines, a mining license is awarded to the company, with due registration of the production company under the Sudanese Companies Act 1925
Reserves of Phosphate found in Mount Kuoun and Mount Lauro in eastern Nuba, has been assessed as 400,000 tons, including some amount of uranium U 2 0 3.
Kaolin, a clay mineral consisting of potassium and Aluminium silicate, is found in some areas of Khartoum and in the south of the River Nile State. Granite is extracted from the southern Wadi Halfa.
Gold is found in three types of geological formations: the Parentheses Gossan formation in the Eriab region of the eastern Nuba Mountains; in quartz-vein formations in the North Kurdufan, Obaidiya, and the Blue Nile region; and alluvial gold along the Nile River and its tributaries, particularly in the Blue Nile and Northern Sudan. The Sudan Gold Refinery Company, with full ownership rights vested with the Central Bank of Sudan, the Ministry of Minerals, and the Ministry of Finance and Natural Economy, produces gold in the range of 270 to 360 tons; silver alloy and silver granules are also byproducts. Gold, iron ore and base metals are mined in the Hassai Gold Mine, located 50 kilometres (31 mi) to the northeast of Khartoum. This is the only gold mine in the country with a production capacity of 90,000 oz/yea
Iron ore reserves lie in the Red Sea Mountains, in Mount Abu Tolo in South Kordofan, and in West Darfur and Baljrawih in River Nile State. The reserves found in the Baljrawih area and Wadi Halfa area have been assessed at 2 billion tons.
Chromium deposits have been established in the Inqasna Mountains, the Nuba Mountains, and the Red Sea Mountains. The estimated reserves of crude chrome is 1 million tons. Chrome has been extracted since the 1970s. Chromite is extracted from the Ingessana Hills, which has an estimated reserve of 1 million tons; production here in the recent years has been about 10,000 tons per year. Manganese is found in the Red Sea Mountains and the Albeodh desert along the River Nile, and in areas around Khartoum State.
Base metals like zinc, lead, aluminium, cobalt, and nickel found in the form of block sulfides are volcanic in nature. Zinc ore is assessed as 60 million tons in the Red Sea area. Lead is found in the Kutum area of North Darfur, aluminium in Darfur, cobalt in the Red Sea, and nickel in the Red Sea, Blue Nile, and South Kordofan.
Uranium and rare earth elements have been found in Darfur pit copper, South and West Kurdufan, Red Sea, and Butana.
