CHATHAM ANNOUNCES NON-BROKERED PRIVATE PLACEMENT

WELLINGTON New Zealand - Chatham Rock Phosphate Limited (TSXV: “NZP”, NZX: “CRP” and
“3GRE” (Frankfurt) or the “Company”) is pleased to announce a non-brokered private placement
consisting of up to 3,500,000 units (“Units”) at a price of CAD$0.05 per Unit (NZD$0.06 or
AUD$0.057) for aggregate gross proceeds of up to CAD$175,000, NZD$210,000 or AUD$199,500
(the “Offering”).

Each Unit will consist of one common share of the Company and one common share purchase warrant
(a “Warrant”). Each Warrant will be exercisable for one common share of the Company at a price of
$0.10 for two years from the date of issuance. In the event that the common shares of the Company
trade on the TSX Venture Exchange (the “Exchange”) at a closing price of greater than CAD$0.15 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 30th day after the date of dissemination of such news release.

The closing date will be on such later date as the Company may determine and is subject to the receipt
of all necessary approvals, including the approval of the Exchange. The Units to be issued under the
Offering will be subject to a hold period under applicable Canadian securities laws until four months
and one day after the closing of the Offering.
It is anticipated that certain directors, officers and other insiders of the Company will acquire Units
under the Offering. Such participation will be 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
intends to rely 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, is expected to exceed 25% of the Company’s market capitalization (as
determined under MI 61-101).
The Company intends to use the net proceeds from the Offering for general working capital.
The securities described in this news release have not been, and will not be, registered under the United
States Securities Act of 1933, as amended (the “U.S. Securities Act”), or any applicable securities laws
of any state of the United States, and may not be offered or sold within the United States or to, or for
the account or benefit of, U.S. persons (as such term is defined in Regulation S under the U.S. Securities
Act) or persons in the United States unless registered under the U.S. Securities Act and any other
applicable securities laws of the United States or an exemption from such registration requirements is
available. This news release does not constitute an offer to sell or a solicitation of an offer to buy any
of these securities within any jurisdiction, including the United States.
