TREVALI ANNOUNCES TSX ACCEPTANCE OF NORMAL COURSE ISSUER BID

The Toronto Stock Exchange (TSX) has accepted Trevali Mining Corp.'s notice to implement a normal course issuer bid (NCIB) to purchase, for cancellation, up to 40 million common shares representing approximately 6.5 per cent of Trevali's public float of common shares (calculated in accordance with the rules of the TSX), having a maximum aggregate purchase price of $20-million, over a 12-month period commencing on Nov. 19, 2018. The NCIB will expire no later than Nov. 18, 2019.

All purchases made pursuant to the NCIB will be made through the facilities of the TSX or alternative Canadian trading systems, in open market transactions or by such other means as may be permitted under applicable securities laws. The price that Trevali will pay for common shares in open market transactions will be the market price at the time of purchase.

In accordance with TSX rules, any daily purchases (other than pursuant to a block purchase exemption) on the TSX under the NCIB are limited to a maximum of 547,457 common shares, which represents 25 per cent of the average daily trading volume on the TSX for the six months ended Oct. 31, 2018. As of Nov. 14, 2018, the company has 831,196,085 common shares outstanding.

Trevali has appointed BMO Nesbitt Burns Inc. to conduct the NCIB on its behalf. Trevali may enter into an automatic purchase plan with its broker to allow for the repurchase of shares during internal trading blackout periods. Any such plan entered into with Trevali's broker will be adopted in accordance with applicable Canadian securities laws and would be subject to prior approval of the TSX.

Trevali believes that initiating the NCIB at the current time represents an attractive use of cash, with now an opportune time to return cash to shareholders. The actual number of common shares that will be repurchased under the NCIB, and the timing of any such purchases, will be determined by Trevali based on market conditions, Trevali's share price, alternative uses of cash and other factors. There cannot be any assurances as to how many common shares, if any, will ultimately be acquired by Trevali under the NCIB.
