Tungsten deposit.
Nyakabingo is located 10 km northwest of Kigali, along the road from Kigali to Musanze (which until 2006 was known as Ruhengeri), in a valley on the west side of the hill, where the road makes a big turn to the west.
The Nyakabingo tungsten mine at Shyorongi near Kigali (Rwanda) is worked underground. Orebodies are sets of thin quartz veins that occur within a domal structure formed by the rectangular intersection of Pan-Rodinian (F3) crossfolds with the main Kibaran (N–S) fold axes. The paragenetic sequence of wolframite–quartz veins displays three very different stages – first, precipitation of quartz, scheelite, and massive, tabular wolframite; second, the near-complete replacement of scheelite by secondary wolframite (reinite); and third, a minor sulphide phase.
