RESIGNATION OF AUDITORS

This announcement is made by the board of directors (the ''Board'') of Persta Resources Inc. (the ''Company'') pursuant to Rule 13.51(4) of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the ''Listing Rules'').

The Board hereby announces that KPMG LLP (''KPMG'') has resigned as the auditors of the Company with effect from August 25, 2020 (Calgary time). As a Canadian limited liability partnership, KPMG believes it would be beneficial to the Company for its auditor to be based in Hong Kong, due to the requirements of the Hong Kong Financial Reporting Council Ordinance (Chapter 588 of the Laws of Hong Kong). KPMG has confirmed in its letter of resignation that there are no circumstances in respect of their resignation as the auditors of the Company that they consider should be reported to the Company. Pursuant to the applicable Canadian securities laws, the Company has given notice (the ''Notice'') to KPMG and Alberta Securities Commission, pursuant to section 4.11 of National Instrument 51-102 Continuous Disclosure Obligations of the Alberta Securities Commission (''NI 51- 102''), that there have been no reportable events, including disagreements, consultations or unresolved issues (as defined in NI 51-102) in connection with the audits of the two most recently completed financial years and with any period subsequent to KPMG's resignation. KPMG confirmed to the Company that they were in agreement with the statement contained in the Notice. The Notice, together with the required letters from KPMG, will be filed under the Company's profile on SEDAR at www.sedar.com.

The Board is not aware of any other matters in relation to the resignation of KPMG which should be brought to the attention of the shareholders of the Company.

The Board is in the process of identifying suitable auditors of the Company to fill the vacancy following the resignation of KPMG. A separate announcement will be made as and when there is any development in relation to the appointment of auditors in accordance with the requirements of the Listing Rules and Canadian securities laws.
