The Morobe Mining Joint Venture (MMJV) is a joint venture between Harmony Gold Mining Company Limited of South Africa and Newcrest Mining Limited of Australia.
MMJV operates Hidden Valley, an open-pit, gold-silver mine and processing plant in Morobe Province, Papua New Guinea.
Hidden Valley will process an estimated 4.7 Mt/y of ore from two open pits. Annual production is expected to be around 250 000 ounces of gold and four million ounces of silver annually.
Ausenco Rylson completed an Asset Management Improvement Program (AMIP) at MMJV. The program comprised the following activities:
As part of the AMIP Ausenco Rylson undertook a complete plant strategy review based on the principles of reliability centred maintenance (RCM). Out of this process, Ausenco Rylson were able to deliver a full suite of maintenance routines.
The outcomes of the AMIP for MMJV include assurance that equipment reliability will meet production needs, ready access to labour and material costing information and an increase in the integrity of its Computerised Maintenance Management System (CMMS).
