• Apprehensive of motivations behind dissident slate as not being in the best interests of shareholders.
• Concerned that a board controlled by Arias Resource Capital and its nominees does not have the company’s long-term interests in mind.

PANAMA CITY, Panama, June 15, 2023 /CNW/ – Alberto Gubbins (the “Shareholder“), a client of Inteligo Bank Ltd., today announced that he intends to vote for the nominees proposed by management of Sierra Metals Inc. (“Sierra” or the “Company“) for the board of directors of Sierra at its upcoming annual meeting of shareholders on June 28, 2023. The Shareholder owns 5,925,000 common shares of Sierra equal to approximately 3.6% of the outstanding common shares of the Company.

The Shareholder is committed to seeing the current management and board of the Company continue to have the opportunity to further implement their plan to rehabilitate Sierra from years of short-sightedness and misguided direction, which was the case when individuals associated with Arias Resource Capital (“ARC“) were previously members of the board.

He believe that the dissident nominees may wish to control the board in order to maximize short term value for the benefit of ARC, the largest shareholder of the Company, at the expense and to the detriment of minority shareholders who believe in the long-term vision and potential of Sierra.

He therefore believe it is critical that each shareholder of the Company exercise our rights as shareholders and vote to ensure that the current leadership team stays in place to further their vision of creating long-term value for shareholders in a manner that benefits all stakeholders of Sierra, and he does not support the election of any member of the ARC slate of nominees.
