Mining Tribe

The Mining Tribe is one of the seven Wakandan tribes in the 2018 film, Black Panther. 
The Mining Tribe was one of the five tribes which fought against one another following the fall of the Vibranium meteorite in what became Wakanda. When Bashenga, the first Black Panther, put an end to the conflict, the Mining Tribe agreed to pledge fealty to the Golden Tribe. The Mining Tribe was solely responsible for all the Vibranium mined, stored and utilized in Wakanda.
The Mining Tribe attended the Incoronation of T'Challa. The Mining Tribe, much like almost all the other tribes, chose not to challenge T'Challa for the throne. They then watched as T'Challa dueled against and defeated the Jabari Tribe leader M'Baku and cheered upon T'Challa's victory.
When Erik Killmonger arrived in Wakanda and claimed the throne, the Mining Tribe Elder mocked hip upon hearing such a demand. However, she was forced to acknowledge that he was within his right when Killmonger was revealed to be the son of late Prince N'Jobu. The Mining Tribe then watched the duel between T'Challa and N'Jadaka and was forced to pledge fealty to the new King N'Jadaka. T'Challa returned, however, and the Mining Tribe agreed to follow him when he got the throne back
