African Eagle Resources said acid leach tests on drill samples from its Zanzui nickel laterite project in Tanzania showed promising nickel extractions.
The tests, carried out by Mintek in South Africa, found nickel extractions, averaging 71% on a solid basis with low sulphuric acid consumption of just 185kg per tonne.
The results are comparable to that of the company’s Dutwa laterite project but acid consumption was less than the Dutwa samples, African Eagle said.
African Eagle managing director Mark Parker said that although the Dutwa project will remain the firm’s priority, Zanzui has a lot of potential.
“Geological mapping, together with the results of the limited drilling to date, suggest that while the nickel grades at Zanzui appear to be marginally lower than at Dutwa the geographical extent of the Zanzui complex is much greater and so potentially this significant laterite is even larger than Dutwa,” Parker said.
