Marketwired Canada


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(R) 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(R) 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."
