'HyperLeach®' Patent Granted in Mongolia for a Method of Oxidative Leaching of Sulfide Ores and/or Concentrates

Alexander is pleased to report that it has received notification that its MetaLeach Limited ("MetaLeach") subsidiary has been granted a patent for a Method of Oxidative Leaching of Sulfide Ores and/or Concentrates in Mongolia, patent number 3671. The patent has a standard term of twenty years from the effective date of 16 December 2011 (being the date of original filing).

This is the same patent that was granted in Australia and announced on 24 October 2012 and describes a method for leaching one or more target metals from a sulphide ore and/or concentrate containing such.

Martin Rosser, Chief Executive Officer, said: "The technology described in the patent has significant potential application in Mongolia. Although the country hosts some important discoveries and mines, including the world class Oyu Tolgoi copper-gold mine (under construction by Rio Tinto and containing some 25Mt of economically viable copper), the majority of the country is still underexplored. We believe there are likely to be extensive sulphide deposits discovered suitable for leaching using HyperLeach®. In addition, there is scope for converting sulphide concentrates, the source of the majority of the world's base metals production and resources, through to metal at the mine site."

Notes

HyperLeach® Process

MetaLeach's HyperLeach® process, although less advanced in its commercialisation than AmmLeach®, has very significant potential for application. HyperLeach® is a hydrometallurgical process which has been developed by MetaLeach for the extraction of metals, especially copper, zinc, nickel, cobalt, molybdenum and rhenium from sulphide ore deposits and concentrates.

The process utilises chlorine based chemistry to solubilise metals from ores under ambient temperature and pressure conditions. The HyperLeach® process can be operated as either heap leach or tank leach.
