Tethyan Resource Corp. Mails Information Circular for Plan of Arrangement with Adriatic Metals plc

Vancouver, July 17, 2020 - Tethyan Resource Corp. (TSXV: TETH) ("Tethyan") is pleased to announce it has mailed the management information circular for its annual general and special meeting (the "Meeting") of the holders of common shares of Tethyan (the "Shareholders"). The Meeting is primarily being held to approve the proposed plan of arrangement (the "Arrangement") with Adriatic Metals plc ("Adriatic") under the Business Corporations Act (British Columbia).

Pursuant to the Arrangement, Shareholders will receive 0.166 of one ordinary share of Adriatic for each common share of Tethyan they hold. The board of directors of Tethyan, after careful consideration, unanimously approved the Arrangement and determined that it is in the best interests of Tethyan and the Shareholders. The board of directors of Tethyan recommends that Shareholders vote for the Arrangement at the Meeting. The directors and certain significant Shareholders representing 54.3% of the issued and outstanding shares of Tethyan have entered into voting support agreements committing to vote for the Arrangement.

As a result of the ongoing COVID-19 pandemic, the Meeting will be held in virtual-only format by telephone conference on Monday, August 17, 2020 at 10:00 a.m. (Pacific). Shareholders and duly appointed proxyholders may attend the meeting by calling the number that appears in the management information circular, as well as on the form of proxy or voting instruction form that have been mailed to Shareholders. These documents also contain information regarding how registered and beneficial Shareholders may vote in advance of the Meeting. In particular, completed proxies or voting instruction forms must be received by Tethyan by 10:00 a.m. (Pacific) on August 13, 2020.

Registered Shareholders will also receive a letter of transmittal for the purposes of exchanging their Tethyan shares for Adriatic shares. In order to receive their Adriatic shares as soon as possible following closing of the Arrangement, registered Shareholders are encouraged to complete the letter of transmittal and return it, together with any Tethyan share certificate(s) held, in accordance with the instructions set out in the letter of transmittal. Shareholders will not actually receive their Adriatic shares until the Arrangement is completed.

Non-registered or beneficial Shareholders, being Shareholders whose shares are registered in the name of a broker, investment dealer or other intermediary should contact their intermediary for instructions and assistance in depositing their Tethyan shares. The Adriatic shares to be issued to Shareholders will be listed on the London Stock Exchange, and may be held under the CREST system, being the central securities depository system for markets in the United Kingdom. Where Tethyan shares are currently registered to CDS & Co., intermediaries must make arrangements with a CREST participant for the shares of Adriatic to be deposited into CREST. In the event that improper, incomplete or no CREST details are provided by intermediaries, the Adriatic shares will be issued to beneficial Shareholders in certificated form. Non-registered or beneficial Shareholders are encouraged to contact their broker, investment dealer or other intermediary to confirm that their intermediary has made arrangements for the Adriatic shares to be deposited into CREST.

Closing of the Arrangement is subject to completion of a spin-off transaction by EFPP d.o.o., as well as customary conditions, including obtaining the requisite approval from the Shareholders, a final order of the Supreme Court of British Columbia, and final acceptance of the TSX Venture Exchange and London Stock Exchange. Upon completion of the Arrangement, Tethyan will apply to delist the Tethyan shares from the TSX Venture Exchange. For further information regarding the proposed Arrangement and related transactions, please refer to the management information circular, available under Tethyan's profile on SEDAR at www.sedar.com and on Tethyan's website at www.tethyan-resources.com.
