A excellent update on the Kibali Gold Project in the DRC , Africas largest Gold mine.
Total cash cost per ounce decreased by 22% to $507/oz, reflecting the benefits from improved grade as well as the lower costs from underground owner mining and power delivery from the newly commissioned Azambi hydropower station.
If they can hold that total cash cost of US$507/oz , they are sitting on a nice little earner of around US$10 Billion not including any of there other leases in and around them !
