Newcrest and Harmony study Wafi-Golpu's underground potential
PERTH (miningweekly.com) – Gold miners Newcrest Mining and Harmony Gold on Friday announced that they would complete a feasibility study on an underground exploration programme at the Wafi-Golpu project, in Papua New Guinea.
In a joint statement, the two companies said that the next phase of work on the Wafi-Golpu project required a feasibility study on an exploration shaft and underground staging platforms, to complete deep underground drilling and bulk sampling of the orebody.
Underground access to the orebody through the exploration shaft would generate essential orebody knowledge required to support a future development decision.
Geotechinical drilling to identify a suitable exploration shaft location had also started.
The joint venture (JV) partners were expected to make a final investment decision on the exploration shaft in the second half of next year, subject to the necessary regulatory approvals.
The JV would also finalise an agreement with the state to provide the framework for an underground exploration phase, ongoing technical and economic studies, and ultimately, the future development and operation of the project.
The Wafi-Golpu project is jointly owned by Newcrest and Harmony and has a mineral resource of about 28.5-million ounces of gold, 9.1-million tonnes of copper and 50.6-million ounces of silver.
