Cranley Investment Holdings, LLC Announces Intention to Vote 9,414,249 Common Shares of Sierra Metals in Favour of Management Slate at 2023 Annual Meeting

• Concerned about Arias Resources Capital's history of governance failures and value destruction at Sierra Metals Inc.
• Believes that Arias Resources Capital's director nominees are being proposed to advance its selfish interests in relation to Sierra Metals Inc. and not in the best interests of Sierra Metals Inc. or its shareholders.

TORONTO, June 13, 2023 - Cranley Investment Holdings, LLC, the holder of 9,414,249 common shares of Sierra Metals Inc. (TSX: SMT) ("Sierra Metals") equal to approximately 5.7% of the Sierra Metal's outstanding common shares, announces today that it intends to vote for the Sierra Metals nominated candidates for the board of directors at the upcoming annual general meeting of the company to be held on June 28, 2023.

As a shareholder of Sierra Metals for approximately 11 years, we seek to protect the long-term best interests of Sierra. We have confidence that management of Sierra Metals has made the difficult decisions that it believes will put the company on a solid footing for future success.

We are aware of Arias Resources Capital's ("ARC") history with Sierra Metals, including what we believe is a history of governance failures and value destruction. We were glad to see ARC's nominees forced off the board of directors in 2021, and do not wish to see ARC or its nominees exercise any future influence over the company.

We do not trust Mr. Arias or ARC, or their intentions in relation to Sierra Metals. For this reason, we do not support the election of any member of the ARC slate of nominees, and we intend to vote in favour of all members of the management slate.
