LONDON, UNITED KINGDOM--(Marketwire - Jan. 12, 2012) - Alexander Mining plc (TSX VENTURE:AXD)(AIM:AXM) ('Alexander' or the 'Company') -
Alexander is pleased to report that it has received notification from the Commissioner of Patents in Australia that its MetaLeach Limited ("MetaLeach") subsidiary has been granted a Standard Patent for a Method for Leaching of a Copper-containing Ore, patent number 2011200703 (this is derived from the Australian national phase entry from the corresponding PCT/AU2008/001027 application). The patent has a standard term of twenty years from the effective date of 11 July 2008 (being date of filing).
The patent covers the leaching of copper from a copper-containing ore using the method steps of curing the ore using a curing agent to produce a cured ore which is leached at atmospheric pressure through the application of an ammonium carbonate solution containing free ammonia. The pregnant leach solution thus produced is passed onto a means for metals recovery.
Martin Rosser, Chief Executive Officer, said: "The grant of a patent in Australia for a Method for Leaching of a Copper-containing Ore is a significant milestone in the protection of the Company's AmmLeach® intellectual property. It is particularly noteworthy given Australia's robust patenting regime and status as having one of the world's biggest mining industries, and with significant potential for our AmmLeach® technology. 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."
