Metals Refining Operations Pty. Ltd. (NMO), PNG's only gold
and silver refinery is operated by Golden West Refining
Corporation Ltd (GWR), a member of the Rothschilds group and
has a strong PNG ownership link through statutory shareholders.
Located in Waigani, MRO has been successful in substantially
increasing production through toll refining for Porgera, Misima,
Tolukuma, Wapolu and, more recently, at Lihir as well as treatment
of alluvial gold from smaller operations. This increased
throughput has resulted in the need to constantly upgrade
equipment, techniques and practices, particularly to continue
quality improvements and meet market demands. The evolution
of these changes are documented and discussed and the probable
future development plans are detailed.
