CHATHAM ROCK PHOSPHATE LIMITED CLOSES PRIVATE PLACEMENT

WELLINGTON New Zealand - Chatham Rock Phosphate Limited, "CRP" or "the Company" (TSXV: "NZP", NZX: "CRP" FSE "3GRE") wishes to announce that the Company has closed a non-brokered private placement (the "Private Placement") of 2,677,822 common shares (the "Shares") at a price of CAD 0.05 per Unit (NZD 0.062) for gross proceeds of CAD133,891.10 (NZD 166,024.96).

The Shares issued pursuant to this Private Placement will be subject to a hold period of four months plus one day after the closing date of this Private Placement as provided by securities legislation. The Private Placement is still subject to final approval of the TSX Venture Exchange (the "Exchange"). No finders' fees were payable in connection with the Private Placement.

Certain insiders of the Company acquired a total of 1,180,000 Shares under the Private Placement, which were considered to be "related party transactions" within the meaning of Policy 5.9 ("Policy 5.9") of the Exchange 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).

Disposition of Funds

The Private Placement funds raised will be used for general working capital.
