- •
Syn-tectonic D2 fluid flow and gold mineralization along the basal, low angle, detachment of the Kagera Supergroup.
- •
Focused fluid flow enhanced by competence contrast between basement gneisses and sedimentary cover.
- •
Mineralization associated with syn- to late kinematic auriferous quartz veins on ramps that initiate fault slip.
- •
Auriferous quartz veins in the cover are constrained to tightly folded and chemically reactive mafic sills and dykes.
