saggy,

You are quite correct - sincere apologies everyone.

I should have checked my own research on the "Research" thread. Lekoumou is the district to the east contining the mountains Zanaga and Bambama. I was thinking these mountains were Zanaga and Lekoumou.

Confusingly, Mount Lekoumou is not in Lekoumou district but in Niari district, on the licence, and is one of the 2 mountains on the french document's page 94 map showing iron deposits, to the immediate west of Mayoko (the other being Makengui). Refer the top of page 95 for reference to these 2 mountain names.

I'm not sure where Mipoundu is though or whether it is the mountain referred to as Makengui.
