Patent Granted in Democratic Republic of the Congo for Method for Ammoniacal Leaching

Alexander is pleased to report that it has received notification from the Ministry of Industry of the Democratic Republic of the Congo ("DRC") that its MetaLeach Limited ("MetaLeach") subsidiary has been granted a Patent for a Method of Ammoniacal Leaching, patent number 2010/3993. The patent has a standard term of twenty years from the effective date of 11 July 2008 (being the date of original filing).

The patent is based on the counterpart South African patent, which was granted in 2010 and claims improved methods for ammoniacal leaching. The DRC patent is directed to improved methods for leaching one or more target metals from an ore, utilising an ammoniacal media. The method(s) comprises the steps of: curing the ore to be leached through the application of an aqueous solution of a curing agent, producing a cured ore; leaching the cured ore at atmospheric pressure through the application of an ammonium carbonate solution containing free ammonia, producing a pregnant leach solution; and passing the pregnant leach solution to a means for metals recovery.

Martin Rosser, Chief Executive Officer, said: "The grant of a patent in the DRC for a Method for Ammoniacal Leaching is excellent news given the major opportunity for the commercial use of our AmmLeach® technology in the country to process copper and cobalt oxide deposits. The new patent is core to our portfolio of patents and patent applications designed to protect the Company's development of unique intellectual property and inventions."
