The "Kasai river" diamond placers are mostly in the northward-flowing tributaries the Tshikapa, Longashimo (Longatchimo), and Tshipumbu rivers.

First discovered in 1909, but largely unexploited until 1913 [Durnez, 2008].

GPS coordinates are currently set for the Kasai River in the town of Tshikapa.
