Chatham Rock Phosphate Projects to benefit from new electricity transmission line

WELLINGTON New Zealand – Chatham Rock Phosphate Limited, “CRP” or “the
Company” (TSXV: “NZP”, NZX: “CRP” FSE “3GRE”) advises that several of our Queensland
based projects (covering both phosphate and selenium) will directly benefit from this game
changing extension of the electricity distribution network.

It has been announced that the Queensland government owned transmission owner/operator
Powerlink will build the CopperString 2032 project, formerly known as CopperString 2.0.

The initial, approximately 840km of new electricity transmission line from Townsville to
Mount Isa, will connect Queensland’s North West Minerals Province (NWMP) to the Northern
Queensland Renewable Energy Zone and to the National Electricity Market.


The Company’s Cloncurry centered phosphate projects, namely the Cloncurry Distribution
Hub and planned Korella MCP plant will directly benefit from this game changing
infrastructure.

The Southern Connection planned to connect Cloncurry to Phosphate Hill will provide power
to Chatham’s Korella North and Korella South mines.

The Company’s Gunnerside selenium project, 20km west of Hughenden, would also benefit
from the new electricity distribution facility at Hughenden.

The overall expanded CopperString project has a budget of $5 billion and includes:

• 500 kilovolt (kV) transmission line from Townsville to Hughenden

2
• 330kV transmission line from Hughenden to Cloncurry
• 220kV transmission line from Cloncurry to Mount Isa
• up to six new substation sites

Powerlink expects to progress early works on the project in late 2023 ahead of construction
commencing in 2024. The project is expected to be completed by 2029.
