Korella North – Advancement to Mining Lease Application

NEWS RELEASE 23-8 April 24, 2023


KORELLA NORTH – ADVANCEMENT TO MINING LEASE APPLICATION

WELLINGTON New Zealand – Chatham Rock Phosphate Limited, “CRP” or “the Company” (TSXV:
“NZP”, NZX: “CRP” FSE “3GRE”) wishes to announce that an early application for the Mining Lease
for the Korella North Mine is now planned so to accelerate the approval process and ensure first
mining of phosphate in December 2023.

This is possible given the large amount of available geological knowledge on the Korella North
deposit thus enabling a mining plan to be prepared to support the early application.

The completion of re-evaluation of the exploration data on Korella North (EPM28589) enabled a
geological model for the shallow 23m thick phosphate deposit to be prepared.

Our mining services supplier Golding Contractors can now develop the mine plan to produce
100,000 tpa of phosphate in the first year and thereafter 250,000 tpa.

The early application for the Mining Lease for the Korella North Mine is being matched with our
work to lodge as early as possible a Development Application for our Cloncurry Phosphate
Distribution Hub.

It is anticipated that operating cash flows from the Korella North mine will, during 2024, provide
working capital while also financing the reapplication for a Marine Consent (environmental permit)
for our Chatham Rise project.
