NEWS RELEASE 24-15 May 23, 2024


APPOINTMENT OF DR GEORG HOCHWIMMER AS A CHATHAM DIRECTOR

WELLINGTON, New Zealand - Chatham Rock Phosphate Limited (“CRP”) (TSXV: NZP, NZX: CRP,
Frankfurt Borse: 3GRE) is very pleased to advise that Munich based Dr Georg Hochwimmer
has today been appointed as a director. This is the logical next step in a close association with
Dr Hochwimmer which now spans eight years since our first meeting at the PDAC conference
in Toronto in 2016.

During that period Dr Hochwimmer has worked actively sourcing equity capital for Chatham
from his networks in Europe, Canada and elsewhere and he is presently our largest
shareholder in his own right.

Dr Hochwimmer operates General Research GmbH, a consulting company providing financial
analysis, corporate finance and investor relations advice. General Research is particularly
focused on emerging growth companies and Dr Hochwimmer has been a founding director of
several technology start-ups.

His PhD qualification, connections and business experience are welcome additions to an
already well-rounded Board and these attributes and his Europe location are particularly
relevant to Chatham’s target markets in that region.
