Ok Tedi Mining Limited (Ok Tedi) has revealed a comprehensive five-year plan to develop the Misima Gold project following its acquisition from Kingston Resources in May 2025. The objective is to commence construction within the current two-year term of the exploration lease.

The company will commence work earlier on the enabling community infrastructure projects that will benefit the host communities ahead of production to support the feasibility and mine development works.

Ok Tedi General Manager for Social Performance and Sustainability, Jesse Pile said: “We’re not waiting until production to make a difference. Roads, power, water, and support for schools and the hospital will start early. These improvements will benefit communities long before the mine is operational.”

Mr Pile was speaking during the company’s first community engagement with the Misima community from 1st – 4th December 2025. This engagement is the start of many that will occur at all levels of stakeholders through the three phases.

He outlined the company’s development plan to the communities which is structured in three key phases: Detailed Feasibility & Permitting, Construction, and Production.

1. Detailed Feasibility & Permitting Phase (2026–2027) Ok Tedi will undertake a detailed exploration at the Umuna, Ewatinona, and Kulumalia pits to optimise the mine plans and plant designs, alongside baseline environmental and social studies. This phase includes securing necessary permits from the Conservation and Environment Protection Authority (CEPA) and the Mineral Resources Authority (MRA), with approvals expected middle of 2027.
2. Construction Phase (2028–2029) When the required permits are granted, major infrastructure construction will commence from mid-2027 to mid-2029, preparing the site for full-scale operations.
3. Production Phase (2030) Commercial production is scheduled to commence after commissioning the plant towards 2030, delivering significant economic benefits to the region.
   

General Manager for Social Performance and Sustainability, Jesse Pile, said Ok Tedi has a clear plan to reopen the Misima Gold Project.

“The above early phases are critical. It’s where we lay the groundwork for everything that follows, detailed exploration, environmental and social studies, and permitting. This is about doing things right from the start leveraging from Ok Tedi’s 40 years of operational experience,” he said.

“Once permits are secured, construction will transform Misima into a hub of activity. This phase is about building the capacity to operate safely and efficiently.”

Mr Pile added: “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.”

As part of its commitment and goodwill to Misima, Ok Tedi will invest in critical infrastructure during phase 1. This vital infrastructures and services will also support Ok Tedi’s activities during the three project phases.

He emphasised that the success of the Misima Gold Project depends on strong and continued support from the local communities. During the engagements communities expressed overwhelming support for Ok Tedi’s plans and infrastructure commitments.

Mr Pile said: “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.’’
