TORONTO--(BUSINESS WIRE)--Sierra Metals Inc. (TSX: SMT) (BVL:SMT) (NYSE American: SMTS) (“Sierra Metals” or the “Company”) confirms that it has received further correspondence from Compania Minera Kolpa S.A. (“Kolpa”) and Arias Resource Capital Management LP (“ARC”) regarding their previously announced unsolicited, non-binding letter of intent.

The Company has been diligently and expeditiously pursuing both short-term financing opportunities and the strategic review process announced in Sierra’s press release dated October 18, 2022. As previously announced, CIBC Capital Markets has been engaged as financial advisor to review strategic options.
