Keegan Resources Inc.: Metallurgical Test Work Commences on New Flowsheet for Esaase Gold Project

Marketwired

VANCOUVER, BRITISHI COLUMBIA--(Marketwire - Oct 25, 2012) - Keegan Resources Inc. (KGN.TO)(NYSE MKT:KGN)(NYSE Amex:KGN) -

Highlights:

  • Metallurgical test work designed to optimize the flotation flowsheet will form an integral part of the current Pre-Feasibility Study
  • Test work will be completed on higher average grade material recently announced in the upgraded resource statement
  • Test work designed to substantially reduce project design and operational risks
  • Test work to confirm earlier metallurgical work which indicated high gold recoveries, substantially lower up front capital and significant environmental advantages

Keegan Resources Inc. ("Keegan" or the "Company") is pleased to announce that an integrated metallurgical test work program on the new Esaase flowsheet has commenced at Amdel Mineral Laboratories, Perth, Western Australia. The results from this program are integral to the final metallurgical design input parameters that will be needed for the completion of the recently commenced Pre-Feasibility Study ("PFS"). The PFS is due for completion in the first quarter of 2013.

Keegan has issued a number technical News Releases in the past two months. The first related to the re-examination of the development options for the Esaase gold project (refer to Keegan News Release dated September 6, 2012). This release described a new flowsheet using flotation technology resulting in lower capital costs and environmental advantages. The second release reported a substantially upgraded Mineral Resource Estimate ("MRE") which showed a 57% increase in the Esaase gold grades whilst increasing Measured and Indicated gold ounces by 5% (refer Keegan News Release dated October 10, 2012).

Based on these releases Keegan has now embarked on an extensive metallurgical testing program at Amdel Mineral Laboratories designed to confirm the following:

  • Earlier and extensive metallurgical test work showed that the Esaase ore body is amenable to recovery via the use of flotation.
  • Examination of those results showed that this flowsheet could be further optimised through grind optimization tests, free gold recovery, flotation reagents suites and residence time in the float and leach plants.
  • Having recently upgraded the MRE it is clear that the expected float results could improve as the Esaase gold grades are now considerably higher than previously modelled.
  • Extensive tailings characterisation tests will also be completed on the Esaase material. The new flowsheet should improve environmental impacts for the project.
  • Part of this program will re-evaluate the CIL flowsheet from previous work completed by Keegan.
  • The sample being used for this test program closely resembles the mine plan for the first four to five years of production and includes weathered, transition and fresh ore.

The integrated metallurgical test work program has been designed to run for the next 12 weeks and should be completed early in 2013, well in time for the scheduled completion of the on-going PFS.

On Behalf of the Board of Directors,

Peter Breese, President & Chief Executive Officer
