Sierra Metals Provides Financial and Operations Update and Announces Strategic Review Process

Sierra Metals Inc. (TSX: SMT) (NYSE American: SMTS) (BVL or Bolsa de Valores de Lima: SMT) ("Sierra Metals" or the "Company") announced today that a special committee comprised of its independent directors (the "Special Committee") has initiated a process to evaluate and consider the Company's current financial and liquidity position, operational challenges and possible financing and restructuring alternatives that may be available to the Company.

Financial and Operational Matters

The Company faces liquidity challenges as a result of the recent previously announced suspension of operations at the Yauricocha Mine and operating losses and negative cash flows that have accumulated, primarily from the Bolivar and Cusi operations.

While mining operations have re-commenced at areas of the Yauricocha Mine, a majority of the operation remains suspended at this time. A precise timeline for achieving full plant throughput has not yet been established.

Absent additional support and increased funding, the Company's ability to continue operations in the ordinary course may be impacted. The Company is monitoring and actively managing its capital to preserve liquidity to support operations and will continue to consult with its financial and other stakeholders.

The Company reiterates that the safety and wellbeing of its employees and contractors remains of utmost importance.

Special Committee

The Special Committee includes all non-management members of the board of directors of the Company. The mandate of the Special Committee includes exploring, reviewing and considering options to optimize the operations of the Company and financing, restructuring and strategic options in the best interests of the Company. The Special Committee has a particular focus on liquidity, near term financing and cash conservation options.

Financial and legal advisors with particular expertise in turnaround and restructuring matters have been engaged to advise on this process.

It is the Company's current intention to not disclose developments with respect to the Special Committee process unless and until the board of directors of Sierra Metals has approved a specific transaction or material steps or otherwise determines that disclosure is necessary.

The Company cautions that there are no assurances or guarantees of the results of the Special Committee review process, management's efforts to improve the current situation or the impact that the process and such efforts will have on the Company's financial and liquidity position or its operations. The Company has not set a definitive schedule to complete the evaluation.
