ROCK PHOSPHATE SAMPLES SENT TO ADVANCE OFFTAKE AGREEMENTS

WELLINGTON New Zealand – Chatham Rock Phosphate Limited, “CRP” or “the Company” (TSXV:
“NZP”, NZX: “CRP” FSE “3GRE”) wishes to announce that as part of the process of negotiating offtake
agreements, samples of Korella phosphate have been sent to phosphatic fertilizer manufacturers.

In the first instance, 3kg samples have been sent to seven fertilizer manufacturers located in New
Zealand, Australia, Canada and Europe for their evaluation. Samples of both Korella 30% P2O5 and
38% P2O5 low cadmium phosphate have been supplied for evaluation by the manufacturers.

To further advance offtake discussions with a European manufacturer, a 300kg sample of 38% P2O5
low cadmium phosphate is now under preparation. The sample will be used by the manufacturer for
extended testing including blending with other phosphates.

The high quality and low cadmium of Korella phosphate provides the basis for producing low
cadmium phosphatic fertilizers that meet the most stringent requirements set by current and
evolving EU standards.
