Beneath the supergene domain, this hole intersected a continuous zone of enriched Itabirite
from 140m, of 229m @39% Fe.
The Mbalam-Nabeba complex intends to produce direct shipping ore hematite for a minimum of 10 years, with a second phase of 15-plus years producing high-grade itabirite
* The second example relates to an iron deposit containing two types of ore: hematite and itabirite
. These two ore materials are deeply embedded at a metric scale, moreover their relative proportions change with depth.
This will also give the essential information for the planning of the first drilling programme, which is set to prove the iron mineralisation in both the hematite and primary itabirite
, said Welborn.
* Concentration of iron ores such as itabirite
, hematite, goethite and limonite;
On top of this, the Project also has the additional 2.38 billion tonnes of Itabirite
at 38 per cent Fe at Mbarga in Cameroon, and we also recently announced that Sundance plans to grow that further through more drilling in 2012.
Sundance will then proceed with development and production of the Itabirite
Phase II is underpinned by further resources of 2.3 billion of itabirite
hematite at 28% iron at Mbalam and 1.7 billion tonnes at 33.9% iron at Nabeba.
* The first optimising control system ever installed in a Brazilian concentrator was fully commissioned last March at CVRD's Timbopeba mine to optimise the grinding of a mix of itabirite
and hematite ore;

He has extensive international experience in iron ore operational design, including plant designs for the Zanaga project in Republic of Congo, MMX and Ponte Verde Itabirite
in Brazil, the Lomonosovskoye project in Kazakhstan, the Shymanivske project in the Ukraine and iron ore operations in Chile.
Anglo American will continue to upgrade the confidence in the Compact Itabirite
Indicated Mineral Resource through further drilling and will work to increase the Ore Reserves through conversion of these resources.
