African Eagle is evaluating a second promising nickel deposit at Zanzui, 50km south of African Eagle's Dutwa Nickel Project in Tanzania.
The Company is evaluating options with regard to expanding exploration to cover the other main areas of the complex including the strong potential for significant sulphide mineralisation."
The Zanzui Complex is a circular, layered ultramafic-mafic intrusion 12km in diameter covering approximately 140km2. The central part of the complex forms a low but prominent hill, which is capped by siliceous duricrust of weathered dunite.
The area was first investigated in the 1980s by the United Nations Development Programme (UNDP), which conducted geophysical, geochemical and mapping work and reporting extensive geochemical nickel anomalies. The UNDP also analysed samples from one drill hole for platinum group metals (PGMs), reporting a single value of 1.24g/t palladium. There are also reliable reports of platinum being panned from the Ng'wangulu River on the eastern margin of the complex.
In January 2013 African Eagle announced a maiden JORC Inferred Resource estimate of 27Mt at 0.81% nickel. Estimated metal contained in the newly defined resource is approximately 219,000 tonnes of nickel.
This maiden resource confirms that the lithology of nickel mineralisation discovered at Dutwa is not limited solely to that property and that at least one further instance of similar mineralisation exists in the region. The Company will explore the potential for ore from Zanzui to become supplemental feed to its Dutwa project.

Small discrepancies may occur due to the affects of rounding
The Inferred resource for Zanzui was prepared by Snowden Mining Industry Consultants Pty Ltd of Perth Australia from data acquired from drill programmes comprising 75 vertical reverse circulation holes drilled on a staggered pattern of 100m and 200m for a total of 4,362 metres of drilling. African Eagle performed the drilling in two phases with the first occurring in August 2008 and the second in May and June 2010. The overall programme was designed only to provide early data for an initial investigation into the Zanzui area and to begin the evaluation of Zanzui as a mineral target.
