Basic Provisions of the
Process Licensing
This leaching process is provided as a two
(2) stage process with the first stage comprised of obtaining the leaching
chemicals, leaching of the ore, precipitating the metals, removing the majority
of the base metals from the precipitates, and regenerating the leaching solution
for additional leaching operations. The second stage consists of conversion
of the gold and platinum group metals (PGM's) to a saleable form, consisting of
a high purity gold button and a separate portion that contains
most of the platinum group metals that were originally in the starting materials.
The Sample Owner will be
responsible for sale of the gold to his normal dealer. The right to use the
process is non-exclusive and the licensor is free to work with multiple
licensees. The use of a mutual non-disclosure agreement is used to protect the
licensor against dissemination of the process details to unauthorized entities
and to protect the licensee against dissemination of his recovery details to
unauthorized entities.
