Exploratory drilling
at African Eagle’s
Dutwa nickel project
in Tanzania
 
London, England — MININGREVIEW.COM — 26 March 2009 – African Eagle Resources plc – a UK-incorporated mineral exploration and development company operating in Tanzania, Zambia and Mozambique – has received highly encouraging final results of acid leach tests and mineralogical analyses on drill samples from its Dutwa nickel laterite project in Tanzania.  

In a statement released here, the company revealed that the leach test results showed high nickel extractions averaging 83% on a solid basis, and very low sulphuric acid consumption, averaging 210 kg per tonne. These compare very favourably with laterite deposits elsewhere in the world.

The statement went on to say that the mineralogical analyses showed that Dutwa was a unique laterite, dominated by silica and with very low iron and magnesium. These characteristics accounted for the exceptionally low acid consumption and high nickel recovery.

In November 2008, African Eagle announced a JORC compliant resource at Dutwa of 31 million tonnes at 1.1% nickel and 0.034% cobalt, containing 340 000 tonnes of nickel and 11 000 tonnes of cobalt.

African Eagle managing director Mark Parker commented: “We are delighted with these results. Dutwa is a unique deposit, with unusual mineralogy which results in high nickel recovery with exceptionally low acid consumption. This bodes very well for commercial development, as the ore should be amenable to tank or heap leaching at atmospheric pressure. Either technology can be implemented at relatively low capital cost,” he added

"We will now commission a scoping study to assess the viability of the project and indicate the best way to proceed,” he continued. “We are currently evaluating bids and expect to award the contract in the next few days. We then expect to commence a second phase of metallurgical test work to evaluate the heap and tank leaching nickel-cobalt extraction technology options in greater detail,” Parker concluded.
