Itabirite Hematite Resources
Resource drilling during 2012 enabled the previous estimated total of 3.72Bt of Itabirite Hematite Resources to be
increased to 4.05Bt grading 36.3% Fe. Importantly, the increase of Itabirite Resources at Nabeba demonstrated
the potential longevity of the Project in both the Republics of Cameroon and Congo.
Itabirite mineralisation is extensive across the entire Mbalam-Nabeba Iron Ore Project area and underlies the
weathered zone of most of the topographic ridges on the permits. Drilling has not yet defined the base of this
mineralisation despite drill holes with vertical depths of over 500m at Mbarga and 400m at Nabeba.
The cross section through the Mbarga Deposit helps to illustrate the massive size of the Itabirite mineralisation
(in blue) as compared to the near-surface High-Grade Hematite Resources (in red). There is a relatively thin
transition zone (in orange) in between the two major domains which, as the name implies, is gradational in nature
of iron grade and rock hardness. The Itabirite domain is bounded along strike by non-mineralised units of schist
(in green) but drilling is yet to determine the depth extent of the enriched Itabirite unit.
