NEWS RELEASE 24-34 November 7, 2024

Korella North’s Environmental Rehabilitation Surety to be confirmed

WELLINGTON New Zealand – Chatham Rock Phosphate Limited (TSXV: “NZP”, NZX: “CRP” and
“3GRE” (Frankfurt) or the “Company”) is pleased to report that the Queensland Department
of Environment, Tourism, Science and Innovation has made their decision on the level of
Environmental Rehabilitation Surety for the Korella North Mine.

The surety as determined by their Estimated Rehabilitation Cost decision is AU$419,304.88
(excl GST). The application to the Department for establishing the level of surety could only
take place once Korella North Mine’s ML100379 was granted. The grant date was 28
th

September 2024 with official notification not taking place until 4
th
October 2024.

The Queensland Treasury will now undertake the risk category assessment of the Estimated
Rehabilitation Cost decision. Based on the risk category allocation, the final relevant surety
or contribution invoice along with the assessment fee will be issued by way of invoice to
Avenir Makatea Pty Ltd (our wholly owned Australian subsidiary) and the holder of Korella
North Mining Lease ML100379.

Once Queensland Treasury receives the acceptable surety or contribution and the assessment
fee, the Queensland Treasury system will automatically notify the Department of Natural
Resources and Mines, Manufacturing and Regional and Rural Development and the
Department of the Environment, Tourism, Science and Innovation that the Environmental
Authority is provisioned, and on-site activities can commence.

Without notification of the posting of the surety no on-site activities can take place.

While Queensland Treasury can take up to 3 months to confirm the level of the bond, due to
the scale of the Korella North Mine the time frame for the approval is expected to be much
shorter.

We will keep shareholders informed when on-site activities can commence.
