Chatham Rise rock phosphate project will reduce carbon emissions

WELLINGTON New Zealand – Chatham Rock Phosphate Limited (TSXV: “NZP” and NZAX:
“CRP” or the “Company") estimates that its process of recovering rock phosphate from offshore New
Zealand will reduce annual carbon emissions by 76,000 tonnes compared with importing the rock
from Morocco. This reduction of 95% of the present emission level equates to immediately taking at
least 19,000 petrol driven vehicles off the roads.

This is significant in the context that there are approximately 5,000 electric vehicles registered now
and the national target is 64,000 by the end of 2021.

Further carbon emission savings will result when Chatham rock phosphate is applied to the land, as
being a slow release fertiliser it can be applied less frequently.

The other directly beneficial environmental effects of using Chatham rock phosphate that we have
advised on numerous occasions are reduced run off, improved water quality, a healthier soil profile,
and much lower cadmium being applied to soils.
