In 1870 Lobengula granted Sir John Swinburne's London and Limpopo Mining Company the right to search for gold and other minerals on a tract of land in the extreme southwest of Matabeleland along the Tati River between the Shashe and Ramaquabane rivers, in what became known as the Tati Concession.[5][6] However, it was not until about 1890 that any significant mining in the area commenced.[citation needed]

Lobengula had been tolerant of the white hunters who came to Matabeleland; he would even go so far as to punish those of his tribe who threatened the whites. However, when a British team (Francis Thompson, Charles Rudd and Rochfort Maguire) came in 1888 to try to persuade him to grant them the right to dig for minerals in additional parts of his territory, he was wary about entering into negotiations. Lobengula gave his agreement only when his friend, Leander Starr Jameson, a qualified medical doctor who had once treated Lobengula for gout, proposed to secure money and weaponry for the Matabele in addition to a pledge that any people who came to dig would be considered as living in his kingdom. As part of this agreement, and at the insistence of the British, neither the Boers nor the Portuguese would be permitted to settle or gain concessions in Matabeleland. Although, Lobengula was illiterate and was not aware of how damaging this contract was to his country, only found out the real terms of the contract he signed as his subjects found out. After going to friendly English missionaries to confirm this rumour, Lobengula sent two emissaries to the British queen, Victoria, but this proved futile.
