Sierra Metals Completes Strategic Review Process, Initiates Annual Base Dividend of US$0.03 Per Share and Appoints Two New Directors to Its Board

Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra Metals" or "the Company") announces today that its Board of Directors (the "Board") has completed its previously announced review of strategic alternatives.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20211007005386/en/

Based on an extensive review of various alternatives, the Board has determined, in consultation with its financial and legal advisors, that maximum value for shareholders will be delivered through the pursuit by the Company of various strategic value-enhancing opportunities.

Within its current assets and diversified extensive resource base, the Company will continue to focus its efforts on growing the production of the metals expected to feed into the anticipated global infrastructure supply demands. The increased focus will apply specifically to copper and steel-making products (zinc and iron ore), with the production of the precious metals as a valuable cost-credit byproduct.

Furthermore, the Company has completed an actionable review of its assets and will consider appropriate further action over the Company's portfolio of assets. This action could take the form of divestments, joint ventures ("JVs") or partnerships, and it could include assets such as the Cusi Silver Mine or exploration targets which lie outside the current operating areas.

Sierra Metals believes in the importance of Environmental, Social and Corporate Governance and will proceed with a heightened focus on these matters with a view to maintaining the best applicable practices in each of these areas. We strive for excellence in fulfilling our environmental and social duties and responsibilities, ultimately sharing increased wellbeing with our workforce and in the communities where we operate.

The Company will continue with a disciplined capital allocation approach and the use of funds on sustaining and growth projects, using a stringent stage-gate process with a close follow-up on implementation and delivery of projects which include:

• Delivery of current Prefeasibility Studies for mine expansion at our 3 operations, starting with Bolivar Mine, followed by Yauricocha and Cusi.

• Advancing with the inclusion into the Company's mine plans of certain near-term underground and brownfield mine opportunities with the aim of increasing the return at the Yauricocha and Bolivar Mines.

Following COVID restrictions that limit the Company on its exploration activities, greenfield exploration on our extensive 110,000-hectare land packages will be reactivated in due course to develop new and expanded mineral resource opportunities. The Company will be open to JVs and partnerships for these opportunities.

Jose Vizquerra-Benavides, Chairman of the Board of Sierra Metals, said, "We have reached the end of the strategic review process announced early this year. This process, which has taken longer than usual due to COVID, has been instrumental in highlighting the value of our current operations and the value-enhancing opportunities that are available for development. The process has allowed us to develop a strategy that will guide our efforts for the coming years, including a renewed focus on green and steel-related metals, the inclusion of added value from our current extensive land holdings and shared wellbeing with our stakeholders."

Luis Marchese, CEO of Sierra Metals, said: "The Company expects to have more robust EBITDA and free cash flow starting next year and carrying on into the coming years. This is a benefit of the recent throughput expansions, which are expected to increase production across our suite of metals, hand in hand with strengthened metal prices based on current consensus metal price projections. Our newly instituted dividend policy has been inaugurated on the back of these positive developments and speaks to our belief in Company and our ability to deliver on our growth initiatives. Over the past several years, we have made significant changes across the organization, streamlining our business, strengthening our team, optimizing our operations, and driving much-improved financial performance. Our operations have not only proven themselves to be quite resilient in these uncertain times, but we also expect to emerge from the pandemic and the strategic review process as a significantly stronger Company with a strong focus on growth and value creation for all shareholders as we execute our strategy."

Annual Dividend

In addition, the Board has authorized the payment of an annual dividend to consist of a base dividend of US$5 million or US$0.03 per share plus an additional amount based on available cash flows generated each year after accounting for planned capital spending, distributions to non-controlling interests, greenfield exploration and mandatory debt service. The initial dividend is expected to be declared in November 2021 and paid to shareholders in December 2021. Additional details of this dividend will be provided in a subsequent press release.
