Geology and mineralization
Ringwani gold project is located on the eastern end of the Musoma - Mara granite greenstone belt and on two intersecting structural faults features controlling gold mineralization in the region.
The Ringwani Gold project lies on Archean greenstone rocks overlain by Proterozoic Bukoban sedimentary sequence consisting siliceous siltstone and tuff shale, intruded by basic sills, conglomerate, grit stone, quartzite and ferruginous sandstone.
Regional Geophysical surveys suggest that two parallel fault zones strike 060 degrees from Musoma to the Mara areas. This structural feature hosts most of the gold occurrence Musoma – Mara greenstone belt. Another set of faults striking 130 degrees is suggested by prominent linear features and a good example is the NW – SE Saguti shear zone marked by topographic depression (Hester, 2005).
Gold mineralization on the Musoma – Mara greenstone is characterized by flat or steeply dipping auriferous quartz veins (gold lodes) with pyrite and base metal sulphide mineralization, and carbonate alteration of the hosting rocks.
A study of the drainage pattern and Mara Flats alluvium sediments stands as an evidence that suggest an intersection of two structural features, associated with gold mineralization similar to those in Golden Glory Mine is within OPG PL, but overlaid by the Proterozoic Bukoban sedimentary rocks. The 060 degree structural feature links the Maji Moto and Kitaharoto gold prospects to the Serengeti OPG property while North Mara Golden Glory Mine is linked by the 130 degree structural feature.
Systematic sampling has been done in this area along the strike of the ore body on 12 artisanal mining pits. The sampling was done along and across quartz veins which are the main carriers of the mineralization. The assay results ranges from 1.3g/T to 27.8g/T. Also tailings stockpiles located within this area were sampled and their assay results ranges from 12.2g/T to 17.8g/T. This is the good indication of the potentiality of this area. Drilling plans and designs have been completed already and actual drilling will start on March 2012.
The Ringwani gold deposit is located in the north part of Tanzania, within the gold-bearing metallogenic zone of the Lake Victoria.
