Korella Fertilisers – Update on Trading Activities

NEWS RELEASE 23-2 8 November 21, 2023

KORELLA FERTILIZERS – UPDATE ON TRADING PROSPECTS

WELLINGTON New Zealand

Chatham Rock Phosphate Limited (TSXV: “NZP” and NZX: “CRP” or the “Company”) advises that Korella
Fertilizers is the trading name for Avenir Makatea Pty Ltd, the wholly owned Australian subsidiary of
Chatham Rock Phosphate Limited.

With CRP’’s extensive knowledge and network of contacts in the phosphate and fertilizer industry
developed over the last 15 years there has always been an interest to trade in low cadmium rock
phosphate and other fertilizer minerals, either our own supply or from other sources.

Over the last 6 months Korella Fertilizers has investigated the potential of trading in third party
Australian produced low cadmium rock phosphate and imported low sodium sulphate of potassium
(SOP). Low sodium SOP is appreciated in the horticultural industry and Korella Fertilizers will focus on
this segment of the market.

Rock phosphate can be used as direct application, in manufacture of high analysis fertilizers and used
in blends with other nutrients.

The domestic market for fertilizer minerals, particularly rock phosphate and SOP, is also very much
driven by logistics.

The Korella Fertilizers distribution centre is in Cloncurry, NW Queensland, the logistics hub for the
whole of Northern Australia. Korella Fertilizers also has a clear understanding of the logistics and the
capability required to service the vast Australian agricultural sector, not just in the North.

We will update shareholders and stakeholders once sales for both low cadmium rock phosphate and
low sodium SOP have been contracted by Korella Fertilizers.
