TETHYAN TO LIST ON LONDON'S AIM

Pre-Admission Announcement Lodged Today in Preparation for Listing Late February
The Directors of Tethyan Copper Company Limited ("Tethyan" or "the Company") are pleased to
advise that the Company today lodged its "Pre-admission Announcement" for the admission of the
ordinary shares in the Company to trading on the AIM market of the London Stock Exchange.
Under the fast track route for AIM admission which is available to Tethyan due to its existing ASX
listing, the Pre-admission Announcement must be made at least 20 days before the AIM listing
date.

Tethyan intends to make the final application for admission to AIM immediately following the
shareholders meeting to approve the previously announced transaction with Antofagasta, which is
expected to be held on 23 February 2006. On this basis, it is anticipated that the AIM listing will take place on or around 28 February 2006.

The proposed AIM listing is intended to broaden Tethyan's shareholder base, offer investors in the
UK and European markets easier access to the Company's securities and thereby improve the
Company's access and flexibility for future capital raisings that may be required to progress its
Reko Diq projects towards development. Approximately 40% of Tethyan's shares are already held outside of Australia. This offshore shareholding percentage will increase further should the proposed agreement with Antofagasta be completed.

As previously announced, the Company has appointed Australian based group RFC Corporate
Finance Ltd as its Nominated Adviser and respected London broker Numis Securities Ltd as its UK
Broker in relation to the AIM listing.

The Company's ordinary shares will continue to be listed on the Australian Stock Exchange
("ASX").

Pursuant to the AIM Rules, all of the Directors and their associates (as defined in the AIM Rules) have agreed not to dispose of any securities in Tethyan for one year from Admission.

Further information is contained in the AIM Pre Admission Announcement and Appendix that have
been submitted to the London Stock Exchange and which have also been lodged on the
Company's website, www.tethyan.com.
