New Zealand - Chatham Rock Phosphate Limited (TSXV: 'NZP' and NZX: 'CRP' or the 'Company') is pleased to announce that the TSX Venture Exchange (TSXV) has accepted for filing the Share Purchase Agreement dated April 28, 2021 between the Company and Avenir Makatea Pty Limited, an Australian incorporated company, pursuant to which the Company will acquire all of the issued and outstanding shares of Avenir.

Avenir, through its wholly-owned French Polynesian subsidiary SAS Avenir Makatea, holds an exploration research permit to explore for phosphate on the French Polynesian island of Makatea. The Makatea project covers an area of 1,035 ha (10.36 km2). The island is a well-known source of phosphate and was previously mined until 1966. Avenir has filed an application for a mining concession over the project area which remains in progress.

The parties originally entered into a non-binding letter of intent regarding the Acquisition dated December 19, 2020, which was announced in the Company's news release dated December 21, 2020. Under the terms of the Acquisition, CRP will acquire from Avenir's shareholders all of the issued and outstanding shares of Avenir in exchange for 17,857,738 common shares of CRP having a deemed value of NZD $0.0916 per share (CAD$0.0815), for total consideration of NZD $1,635,769 (CAD$1,455,000; AUS$1,500,000). Upon completion of the Acquisition, the common shares issued to the Avenir shareholders will comprise approximately 29% of CRP's total issued and outstanding shares, not including any common shares to be issued upon completion of the private placement announced by the Company on March 21, 2021 which will be completed following closing of the Acquisition (the 'Private Placement').

Following closing of the Acquisition, the Company will focus its efforts on completing Avenir's application for the mining concession as described below and developing an appropriate work program and budget for the continued exploration and development of the Makatea project. It is expected that the Acquisition will be completed on or about June 30, 2021 and the Private Placement will be completed by July 17, 2021.

Upon completion of the Acquisition, Mr. Colin Randall, a director and major shareholder of Avenir and since 2016 its full-time Executive Chairman, will be appointed to CRP's Board of Directors.

Mr. Randall and a trust in which members of his family hold an interest will receive an aggregate of 10,721,785 common shares of CRP upon completion of the Acquisition, representing approximately 17.4% of CRP's issued shares prior to the completion of the Private Placement. Mr. Randall is a mining engineer with over 50 years-experience and has for 30 years provided independent consultant services in the fields of mining, marketing, management and development to a wide range of clients including mining companies, potential investors, banks, insurance companies and trading houses.

He is a graduate from the University of New South Wales in Mining Engineering, a Fellow of the Australasian Institute of Mining and Metallurgy and is a Past Fellow of the Chartered Institute of Logistics and Transport and is a past director of a number of mining, energy and exploration companies.

Summary of Avenir's Significant Assets

Avenir's flagship property is the Makatea Phosphate Project. This combined rehabilitation and phosphate mining project is located on Makatea Island approximately 240km northeast of Tahiti, French Polynesia. The elevated island is a well-known source of phosphate and was previously mined from 1908 to 1966. The primary phosphate deposits form through the precipitation of carbonate fluoroapatite within marine sediments before the Island was elevated up to 100m from the surrounding ocean. Samples of the phosphorites of Makatea have an average P2O5 concentration of 33.2% and have very low impurities.

SAS Avenir Makatea (wholly-owned subsidiary of Avenir) was granted an exploration permit on 28th January 2014 and in June 2016 applied for a mining concession to mine/rehabilitate an area of 600 ha of previously mined land. The Project has a 30 year life.

The application is now being processed under the terms of a new Mining Code for French Polynesia that was promulgated in January 2020. The existing Environmental Code is currently being harmonized with the new Mining Code.

The Project is subject of a Public Enquiry process that leads to recommendations to the Council of Ministers for the grant of the Mining Concession. The Public Enquiry, which will be based on the presentation of an updated Environmental Impact Assessment and an Economic Benefit Analysis, is expected to be announced in Third Quarter of 2021.

Nominated consultants in French Polynesia in association with the staff of SAS Avenir Makatea will prepare the two reports and present these to the public in advance of /and during the one-month public enquiry period. Following the enquiry, the process for determining the application is set out by the Mining Code including presentations to the nominated Mining Committee. The Committee makes its recommendations to the Council of Ministers. Following the past four years of intensive consultation with landowners of Makatea and the continuing consultation with Government since 2011, Avenir looks forward to the granting of the Mining Concession in early 2022.

Future Growth Strategy (to be further updated)

With the completion of the merger of CRP and Avenir imminent, we are able to advise that Avenir has been conducting due diligence on phosphate projects in Queensland and Northern Territory since August 2020. To date four projects have been subject to due diligence.

Due diligence on one of the projects was completed last year but the project owner decided to proceed to develop the phosphate project itself without Avenir's involvement.

The three other projects are now subject to a due diligence review by CRP, two in Queensland (both with mining leases) and one in the Northern Territory (NT), all with defined JORC resources.

Due diligence on one of the Queensland projects, is at an advanced stage and a site visit has been completed. Due diligence on the NT phosphate project and the other Queensland are progressing on the basis of utilising innovative technology to produce a high value product that can stand the high transport costs to market.

CRP is taking advantage of the work already undertaken by Avenir to expand and deepen its overall ambitions to build an international phosphate mining and trading house focusing on the rapidly expanding organic phosphate marketplace.
