Mashamba East is an open pit copper mine near to Kolwezi in Katanga Province, Democratic Republic of the Congo.

[1] The mine covers an area of 11.04 square kilometres (4.26 sq mi).

[3] The mine operated from 1985-1988, during which period it produced 9.8 million tonnes of ore at an average grade of 4.96% copper and 0.35% cobalt.

[4] As of 2009, total measured and indicated resources were 75 million tons at 1.80% copper and 0.38% cobalt.

Following the friendly merger of the Katanga Mining and Nikanor assets, there was speculation that the Dikuluwe and Mashamba West deposits were being transferred to Gécamines, and would be exploited by a joint venture owned 32% by Gécamines and 68% by a Chinese consortium.
