Solomon Resources Ltd. reported that its Rwandan exploration crews have started preliminary exploration of the Gipfizi Ridge tin and coltan (niobium-tantalum) target, located 20 kilometers north of the town of Gitarama, Republic of Rwanda. 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.

The pegmatites identified to date appear to occupy regional structural breaks sub-parallel to the East Africa Rift, with thickness ranging from several centimeters to 30 meters and lengths ranging from 10 meters up to 2400 meters. The vertical extent of the pegmatites is not known as only the uppermost weathered portions have been investigated by artisanal mining. Solomon field crews have established a field office in the rural area north of Gitarama and hired local labourers to excavate test pits under the direct supervision of geological contractors.

Representative samples have been obtained from exposures of pegmatite dykes in this area and bulk samples of alluvial and eluvial material have been concentrated in the field to assess the previously unexplored placer potential of the ground adjacent to the mineralized dykes.
