Trevali Announces Extension of CCAA Stay Period

VANCOUVER, Aug. 29, 2022 - Trevali Mining Corp. ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) (Frankfurt: 4TI) announces that following the granting of the initial order (the "Initial Order") from the Supreme Court of British Columbia under the Companies' Creditors Arrangement Act ("CCAA") on August 19, 2022, a comeback hearing in respect of the relief granted pursuant to the Initial Order was held today.

Pursuant to the Initial Order, the Company obtained protection from its creditors for an initial period of ten (10) days (the "Stay Period") and FTI Consulting Canada Inc. was appointed as monitor of the Company (in such capacity, the "Monitor"). The Court has today issued an order extending the Stay Period until October 6, 2022.

On August 22, 2022, as a result of the Company filing for protection under the CCAA, the Toronto Stock Exchange ("TSX") suspended trading of Trevali's common shares and advised the Company that a delisting review would be required by the TSX. The TSX is reviewing the eligibility for continued listing on the TSX of the common shares of the Company pursuant to an expedited review process. The delisting review is expected to take place on September 1, 2022, and the Company expects that the common shares will be delisted following such review.

Further updates will be provided as appropriate. A copy of the Initial Order and all materials related thereto, as well as any other information regarding the CCAA proceedings, are available on the Monitor's website at http://cfcanada.fticonsulting.com/trevali/.
