History
On June 6, 1918, the mining rights of the ''Companhia de Pesquisa Mineira de Angola (PEMA)'', which was formed on 6 September 1912, were transferred to Endiama. PEMA got these mining rights on 31 March 1913. On 4 December 1920, the Portuguese High Commissioner for Angola signed a contract with Endiama, giving the company exclusive rights for diamond prospection and mining.
On 28 February 1970, Diamang and
De Beers Consolidated formed the joint venture
Condiama for the commercialization of diamonds.
After Angola gained independence, the major part of Endiama's capital was nationalized, by decrees 61/77 of 24 August 1977, and 255/79 of 11 December 1979. From 1978 to 1986, the British company ''MATS'' managed and serviced the operations of Diamang.
