NEWS RELEASE 23-33 December 20, 2023

AUSTRALIAN GOVERNMENT ADDS SELENIUM TO CRITICAL MINERALS LIST

WELLINGTON New Zealand

Chatham Rock Phosphate Limited (“CRP” or the “Company”) (TSXV: “NZP”, NZX: “CRP” FSE
“3GRE”) is pleased to advise that selenium has been added to Australian Government’s
Critical Minerals List – see here for further details.

Our Selenium Project comprises two granted selenium-focused exploration areas, one near
Hughenden (“Gunnerside” EPM 28676) and the other near Blackall-Tambo (“Tambo”
EPM28606), both in Queensland.

The addition of selenium to the Australian Critical Minerals List provides significant further
impetus to the Company’s activities.

Background

The Australian Government has (16

December 2023) updated the list of Critical Minerals
deemed essential to the nation’s energy and security requirements - and plans to scope the
creation of Strategic Critical Minerals Hubs around the country.

The Australian Government has also created a new list of Strategic Materials.

Both lists contain minerals that are important for Australia’s modern technologies, economies
and national security.

These include:

• supporting the transition to net zero emissions.
• advanced manufacturing.
• defence technologies and capabilities.
• broader strategic applications.

Australian Critical Minerals List

The Critical Minerals List comprises minerals:

• essential to modern technologies, economies or national security, specifically the
priority technologies set out in the Critical Minerals Strategy
• for which Australia has geological potential of resources
• that are in demand from our strategic international partners

• that are vulnerable to supply chain disruption.

The updated list consists of 30 minerals or groups of minerals. Critical Minerals are crucial to
the energy transition, and the newly listed commodities are all used in the defence and
technology sectors.

The Critical Minerals list has expanded to include fluorine, molybdenum, arsenic, selenium
and tellurium; and more closely aligns Australia’s list with those of its international strategic
partners.

The announcement by Australian Government’s Minister for Resources and Northern
Australia, Madeleine King, said the changes followed extensive consultation with industry,
the public, and states and territories, and would support Australia’s growth as a major
exporter of clean energy materials.

“The updated Critical Minerals List and the new list of Strategic Materials will help
government focus on those commodities needed to create jobs, keep us secure and power
our economy,” Minister King said. “ These minerals are critical to the greening of our economy
and the defence of Australia and our allies.”

Management Comment

Chris Castle, President and CEO said “This announcement of inclusion of selenium in
Australia’s list of Critical Minerals underlines the Company’s decision to take up its two
Queensland exploration areas specifically targeting selenium to create its Selenium Project.

The Selenium Project is managed through our subsidiary company Organoselenium Pty Ltd
who have been advancing studies into the occurrence, distribution within the strata, methods
of concentration and extraction of selenium.

We will keep shareholders and stakeholders advised as we progress the Selenium Project.”
