("Alexander" or the "Company")
'HyperLeach(R)' Patent Granted in Europe 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 Europe, patent number 2435590.
Metaleach has initiated the process of validating the patent in
Germany, Poland and Turkey. These member states were identified as
key jurisdictions that represent opportunities for the
HyperLeach(R) process. MetaLeach anticipates that the patent will
be validated in these individual member states, providing an effect
patent term of 20 years from the effective date of 26 May 2010
(being the date of original filing).
The patent 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
each of Germany, Poland and Turkey, both for sulphide deposits and
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(R) Process
MetaLeach's HyperLeach(R) process, although less advanced in its
commercialisation progress than AmmLeach(R), has very significant
potential for application. HyperLeach(R) 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(R) process can be operated as either heap leach or
tank leach.
