For those who are confused about the meaning of the name it is better to think of it in this manner "Once upon a time there was a river and stream which derived its name from the antelopes that would go to drink from there. Then some foreigners came and found some copper and started mining works on the land. In the style of the local chiefs, they also adopted the two animal totems and named their mine after the antelopes, roan being the mpelembe, nsha being the duiker. They amassed a lot of wealth from the mine and lived happily ever after."
