Ok Tedi Mining has revealed a five-year plan to develop the Misima gold project following its acquisition from Kingston Resources.
The project, located 625km east of Port Moresby in Milne Bay, was acquired for $A60 million ($US38 million) in May 2025 with plans now in motion to commence construction within two-years of the exploration lease.
It’s understood Ok Tedi will commence work earlier than expected on enabling community infrastructure projects ahead of production to support feasibility and mine development works. This, the company said, will benefit the host communities.
The development plan is structured in three phases: detailed feasibility and permitting, construction and production, and are set to be complete by 2030.
During the 2026/27, the company will carry out further exploration at the Umuna, Ewatinona and Kulumalia pits to optimise mine planning and plant design, alongside baseline environmental and social studies.
Approvals will be sought from the Conservation and Environment Protection Authority and the Mineral Resources Authority, with decisions expected by mid-2027.
Subject to those permits, major construction is scheduled to run from mid-2027 to mid-2029, with commercial production targeted to begin around 2030 following plant commissioning, bringing significant economic benefits to the region.
“Community support is the foundation of this project. We’ve seen incredible positivity from Misima people, and we will continue to engage openly, transparently, and honestly,” Ok Tedi general manager for social performance and sustainability Jesse Pile said.
“Before the end of 2030, we aim to see Misima in full production again. This will bring real opportunities for jobs, spin-off business, and long-term benefits for the island.”
