NEWS RELEASE 25-027 December 23, 2025

CHATHAM ROCK CLOSES PRIVATE PLACEMENT

WELLINGTON New Zealand – Chatham Rock Phosphate Limited, “CRP” or “the Company”
(TSXV: “NZP”, NZX: “CRP” FSE “3GRE”) is pleased to announce the closing of its non-brokered
private placement (the “Offering”) previously announced October 27, 2025, for the issuance of
3,162,995 units (the “Units”) at a price of CAD $0.05 per Unit (NZD 0.062 or AUD 0.055) for gross
proceeds of CAD $158,150 (NZD 196,106 or AUD 173,965).

Each Unit will consist of one common share in the capital of the Company and one (1) share purchase
warrant (“Warrant”), which shall be transferable subject to applicable securities legislation. Each
Warrant will entitle the holder thereof to acquire one common share at a price of CAD $0.12 per share
at any time prior to the date that is twelve months from the date of issuance.

In the event that the common shares of the Company trade on the TSX Venture Exchange at a closing
price of greater than CAD $0.20 per common share for a period of 20 consecutive trading days at any
time after four months and one day after the closing date of the Offering, the Company may accelerate
the expiry date of the Warrants by giving notice to the holders thereof by way of a news release and in
such case the Warrants will expire on the 30
th
day after the date of dissemination of such news release.

The securities underlying the Units are subject to a hold period under applicable Canadian securities
laws until April 24, 2026. The Offering is still subject to final approval of the Exchange. No finders
fees were paid in connection with the Offering. The Company intends to use the net proceeds from the
Offering for general working capital.
Certain insiders of the Company acquired Units under the Offering. Such participation was considered
to be “related party transactions” within the meaning of Exchange Policy 5.9 (“Policy 5.9”) and
Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions (“MI
61-101”) adopted in Policy 5.9. The Company is relying on the exemptions from the formal valuation
and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a)
of MI 61-101 in respect of related party participation in the Offering as neither the fair market value (as
determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration
for, the transaction, insofar as it involves the related parties, exceeded 25% of the Company’s market
capitalization (as determined under MI 61-101).
