Active Gold & Gemstone Mining Concessions
Our mining operations combine experienced local miners, qualified mining engineers, and responsible community stewardship. We focus on high-grade gold vein extraction, underground reef shafts, alluvial processing, and mineral property development.
A NEMA-approved small-scale gold processing plant (NEMA/PR/SYA/002) at Nyangoma, Bondo Sub-County, serves as a central regional processing hub alongside extraction sites at Oyugis and Lolgorian.
We practice responsible mining that strictly safeguards water tables, manages tailings with zero hazardous discharge, and contributes directly to local employment and infrastructure.
