Ok Tedi Mining Limited | Papua New Guinea

Project overview
Ok Tedi Mining Limited (OTML) is proudly a 100% owned Papua New Guinea (PNG) company which has been mining copper, gold and silver at Mt Fubilan open pit operations for over 38 years. Success is measured by safety and financial performance, people development, social development indicators and the management and mitigation of environmental impacts.

OTML are committed to openly, honestly and transparently reporting their strategy, performance and impacts to their stakeholders, through the Annual review reports.

Whilst the mine still has a number of years of operation, OTML are also required by the State of Papua New Guinea to prepare and submit a revised Mine Closure Plan (MCP) every three years pursuant to the Ok Tedi Mine Closure and Decommissioning Code 2001.

Our involvement
EMM has been working in partnership with Ok Tedi Mining since 2020. As a trusted advisor, EMM has been engaged to work on both Ok Tedi’s Mine Closure Planning strategy and the development of their Annual Review which includes an integrated sustainability report and the company’s Financial Statements. The reports are externally assured. EMM successfully delivered the 2021 and 2022 annual reporting working collaboratively with the OTML management and key stakeholders.

The Mine Closure Planning Strategy involves updating and finalising the suite of Mine Closure Plan (MCP) documents, including the MCP, Mine Area Rehabilitation Plan, Post Closure Monitoring Plan and Financial estimates for the Closure Bond.

The revised suite of 2022 MCP, updated the previous 2019 plans and incorporated the the significant engineering changes completed in the previous three years, increased disturbance due to mine operations, the revised life of mine extension and progressive rehabilitation.
