Carbonate-hosted copper-lead-zinc mineralization in Upper Proterozoic rocks in the historic Boko Songo-Mindouli district. There was significant high-grade production from the district in French colonial times and some historic mines are presently being rehabilitated by Chinese and other foreign companies. The project area is located approximately 70-100 kilometres north-west of the capital city of Brazzaville.

Known mineralization in the district includes:
- Copper-dominant karst-fill mineralization (3-5% copper),
- High-grade (>10% copper) chalcocite mineralization replacing specific carbonate horizons,
- Fracture-controlled moderate grade copper mineralization (1-2% copper), and
- Lead-zinc veins and carbonate replacement bodies (5-15% lead and zinc).

"Renéville is a small village about 3km south of the Renéville mine, The mine consists of three old prospects which probably produced less than 100,000 tonnes of ore. The largest is the Indus Mine, a couple of hundred meters to the north is the much smaller Amelie working and then to the south is an adit called Bel. From what I can see only the Indus workings produced any significant specimens. Blocks of limestone veined with cuprite malachite, dioptase and rare plancheite were found in trenches dug by NGEX Resources but no in-situ material was found."
