Further to the announcement of 12 July 2017 relating to its application for a secondary listing on the TSX Venture Exchange (the "TSX-V"), Tethyan Resources plc ("Tethyan" or the "Company") is pleased to announce that it has obtained a receipt on 17 August 2017 in connection with the filing of a non-offering final prospectus in the province of British Columbia. As a result, the Company is now a reporting issuer in the province of British Columbia. A copy of the prospectus is now available on the Company's website at www.tethyan-resources.com. In addition, the TSX-V has conditionally approved on 16 August 2017 the Company's application to list its ordinary shares on the TSX-V. Final approval of listing on the TSX-V is subject to the Company satisfying certain customary conditions required by the TSX-V. The Company is working to satisfy these conditions and will provide an update once the official TSX-V listing date has been determined.

Tethyan CEO Peter Mullens commented: "we are delighted to see this progress with getting dual listed on the TSX-V. It is a key step in our strategy to have better access to capital markets and broaden our shareholder base".
