AIM and JSE-listed African Eagle Resources has discovered nickel sulphide and platinum group elements (PGEs) in the strata below its flagship nickel Dutwa project in Tanzania, including a shallow mineralised zone immediately below the known laterite deposits at Wamangola.

“The discovery of visible sulphide mineralisation and the strong values achieved are potentially very exciting for the Dutwa project. We have long known the significance of Dutwa’s laterite deposits but the presence of nickel and PGEs in sulphides in the strata immediately underlying these deposits is further evidence of the strength of Dutwa overall.

“We are planning to implement a cost effective exploration programme to explore and quantify the extent of the sulphide mineralisation and to begin to define what may be another aspect of the potential nickel province that may exist in northern Tanzania,” says African Eagles CEO Trevor Moss.

African Eagle said that during the resource drilling programme conducted between 2008 and 2012, at the Dutwa nickel laterite orebodies, it was company procedure for all the drill holes to extend through the laterite horizon and ensure delineation and to terminate in the underlying bedrock.

Further, a review of these bedrock intersections has revealed a number of holes with elevated nickel and PGE values which appeared to be inconsistent with the known laterite mineralisation. A recent re-examination of the samples indicated the presence of sulphide mineralisation.

The company advises that selected samples had previously been sent to Rhodes University in South Africa for petrographic and microprobe analysis which confirmed the presence of cobalt rich and cobalt poor pentlandite such as nickel sulphide.

Meanwhile, African Eagle noted that all the mineralised intersections are from the tail of the laterite resource drillholes where visible sulphides have been observed with grades of more than 0.4% nickel, while a 0.4 g/t cut off has been used for platinum and palladium results and 0.5 g/t for gold.

The company is now planning to undertake a programme of geophysical surveys, including electromagnetic and induced polarisation in order to delineate the current extent of the known mineralisation at Wamangola and to define additional areas for drill testing.
