NEWS RELEASE 24- 29 September 16, 2024

PHOSPHATE INCLUDED IN DRAFT CRITICAL MINERALS LIST RELEASD BY
NEW ZEALAND GOVERNMENT

WELLINGTON New Zealand – Chatham Rock Phosphate Limited (TSXV: “NZP”, NZX: “CRP”
and “3GRE” (Frankfurt) or the “Company”) is very pleased to report that phosphate rock and rare earth
minerals have been included in a just-released list of minerals deemed critical to New Zealand.

The draft list has been developed by Wood Mackenzie and is one of the key actions identified in the
New Zealand Draft Minerals Strategy.

A critical mineral is defined as:

• essential to New Zealand’s economy, national security, and technology needs, including
renewable energy technologies and components to support our transition to a low emissions
future
• in demand by New Zealand’s international partners.

The draft list identifies 35 minerals that are essential to New Zealand’s economic functions, are in
demand by our international partners, and face high risks to supply domestically and internationally.

Once finalised, the critical minerals list will contribute to New Zealand’s work on critical international
supply chains and allow the Government to investigate specific actions for securing better access to the
minerals deemed critical. This could include strategic pathways for development of specific minerals.

CRP holds a granted mining permit over an 820 square kilometre area in the Chatham Rise that holds
an independently verified rock phosphate resource of 23.4 million tonnes. For more information see the
NI 43-10 report on our website.

Rare earth minerals are also present in significant quantities but an economically viable method to
recover them is yet to be established.

The Company believes its prospects for gaining the necessary environmental consent for mining on the
Chatham Rise is much enhanced by this development of a critical minerals list, as well as the related
Fast Track permitting process also now being established by the New Zealand government.
