Solomon Resources Limited (TSXV:SRB) has announced that its Rwandan exploration crews have begun preliminary exploration of coltan (niobium-tantalum) target at the Gipfizi Ridge in Rwanda.

As quoted in the press release:

The primary targets of the Rurembo Tin Project are Neo-Proterozoic pegmatites mineralized with cassiterite and columbite-tantalite (coltan). At the regional scale more than 130 large pegmatite dykes have been mapped to date but this mapping reflects only a small portion of the inter-massif area of the Rurembo Licence Area in which a far greater number of unmapped pegmatites are thought to exist.
