Tambao is a Manganese deposit and potential mine site in the Oudalan Province, located in the Sahel Region, which the far northeastern part of Burkina Faso. Tambao has been estimated, when exploited, to be one of the largest deposits in the region. Its development, a major priority of the Burkinabe state, has been an on and off project since the 1990s. Barely served by roads or other infrastructure, the Tambao reserves are some north of Kaya and northeast of the capital, namely Ouagadougou. The Tambao Airport has been recently built to serve the deposit and the corresponding villages. ==Industry== Manganese is mined here. For at least two decades it has been considered the most potentially lucrative mining resource in Burkina, and is believed the region's largest Maganese deposit, estimated at 20 million tonnes at %52 to %53 Manganese to ore, making it one of the cryptomelane-richest ore resources in the world.〔(Tambao site ) Minedat.org, Jolyon Ralph and Ida Chau 1993-2011.〕〔(Tambao Mine, Burkina Faso: List of minerals arranged by Dana 8th Edition classification ) Minedat.org, Jolyon Ralph and Ida Chau 1993-2011.〕〔(BURKINA FASO : LE MANGANÈSE DE TAMBAO ATTISE LES CONVOITISES ), Dossier specicial du ''Africa Mining Intelligence'', September 2011.〕 The site's inaccessibility and lack of infrastructure have prevented wide scale exploitation.〔("Tambao." ) Encyclopædia Britannica. Encyclopædia Britannica Online. Encyclopædia Britannica, 2011. Retrieved 04 Oct. 2011.〕 Most recently, in 2010, mining companies refused bid on construction of the necessary infrastructure for mining unless the government granted them mining concessions in the area.〔Historical Dictionary of Burkina Faso, by Lawrence Rupley, Lamissa Bangali, Boureima Diamitani, 2013, Third edition, Scarecrow Press, Inc. ISBN 978-0-8108-6770-3〕 In 1993 InterStar Mining carried out 6 months of operations here, but were plagued by lack of supportive resources.〔 Large scale exploitation was only again attempted by the Fompex consortium in 2004 and was quickly halted.〔 Apart from total lack of operations infrastructure (power, water, construction or employment base) the biggest hurdle to commercial exploitation of the Tambao reserves is the lack of an all weather roadway capable of supporting the transport fleet needed to move ore the to Kaya, the nearest city connected to the Burkinabe road network.〔 In 2010, the Burkinabe government carried out talks with investors from India aimed at building a 250 km railway line from Tambao to Kaya.〔(Un chemin de fer pour Tambao au Burkina ). Africa Mining Intelligence N°224, 2010-04-07.〕 Later that year, the Burkinabe government tendered a series of openings for mining operations in Tambao, with Wadi Al Rawda Industrial Investments one early candidate thought likely to gain at least some concession.〔(Manganèse de Tambao : Wadi recourt à l’arbitrage ). Africa Mining Intelligence N°231, 2010-07-21.〕 In 2010 two consortia emerged offering to develop an integrated mining and rail system which, in some proposals, would not only mine and process ore, but build longer rail lines to feed into the Ivorian rail network for export at the port of Abidjan. Major contenders were a Singaporean/Indian joint venture, the Nice Group company, and a tie up of the Japanese firm Mitsui Rail Capital and Brazilian mining giant Vale S.A.〔(Vale-Mitsui cible le manganèse de Tambao ).
