VANCOUVER, Sept. 6, 2022 - Trevali Mining Corp. ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) (Frankfurt: 4TI) announces that following a delisting review by the Toronto Stock Exchange ("TSX"), the Company's common shares will be delisted effective close of market on October 3, 2022.

Trading of the Company's shares has been suspended since August 22, 2022 as a result of the Company filing for protection under the Companies' Creditors Arrangement Act ("CCAA") and this suspension will continue until the delisting takes effect.
