Mapping and sampling programs have defined targets with potential for high-grade 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 kilometres west of the capital city of Brazzaville. Most of the project area is accessible by road and the rail line connecting Brazzaville with the port city of Point Noire passes between 5 and 30 kilometres south of the major prospects identified to date. 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).
There is evidence for all four styles of mineralization on the Company's licenses. Controls on mineralization include regional WSW-ENE trending faults, NNW-SSE transverse faults, and a regionally extensive carbonate horizon. Tight folding in the vicinity of mineralization suggests that mineralization was broadly coincident with a period of compressional deformation. The district shows similarities, in size and distribution of deposits, to the Pine Point District in Canada.
NGEx plans to conduct induced polarization (IP) surveys over the most prospective areas in September 2010 with follow-up drilling planned for later in the year. Table 1 below summarizes the principal prospects on the Company's licenses.

Assay data from selected rock chip samples of gossan and high-grade mineralization received to date is summarized in Table 2. Some of the samples, especially at Reneville, were taken from selected high-grade portions of the occurrence, and may not represent the average grade of any deposit or mineralization.

Exploration LicensesThe licences are on strike with a historic mining district with numerous high grade copper-zinc-lead bodies hosted in carbonate rocks. The style of mineralization discovered to date suggests potential for multiple relatively small, but very high grade polymetallic ore bodies. The project area has reasonable infrastructure near Brazzaville-Pointe Noire railway.
Africa ProjectsThe Company has projects in Eritrea, Burkina Faso and Republic of Congo.
