Active gold vein mining, concessions and mineral processing across East Africa
Green Ngoria provides all aspects of gold mining services. The company began by pursuing mining activities in Tanzania and later extended its operations into Bondo in Siaya County, Kenya, and into Taita Taveta.
Mining is the core discipline the rest of the business grew around: our engineering, construction, mechanical, electrical and supply divisions all exist to support producing sites and the processing plants that serve them.
A small-scale gold processing plant at Nyangoma, Bondo Sub-County, approved by NEMA (Permit Ref: NEMA/PR/SYA/002), sits at the operational centre of our Kenyan gold extraction activity.
