Sierra Metals Announces Changes to Organizational Structure Following Strategic Review

TORONTO /Jan 27, 2022 /Business Wire/ Sierra Metals Inc. (TSX: SMT) (NYSE American: SMTS) (BVL: SMT) (“Sierra Metals” or the “Company”) is pleased to announce the completion of an internal organizational review, following the review strategy announced at the end of 2021.

Sierra Metals is bolstering its current operating portfolio through various upscaling opportunities. These include:

– Increased emphasis on the production of copper and steel products such as zinc and iron ore;

– Advancement of the Company’s mine expansion plans, with the aim of increasing the yield of the Yauricocha and Bolivar mines;

– Reactivation of brownfield and greenfield exploration activities, across Sierra’s vast resource base;

– Increased focus on ESG, human capital and permits

In order to align the organization to effectively achieve these goals, as well as to overcome current operational issues, the following appointments have been made:

James León – Vice President, Operations

Effective February 1st, following his previous appointment as Country Manager Perú, Mr. León will now manage Yauricocha and Bolivar operations. Mr. León will be based in Mexico. He will oversee the delivery of increasingly improved operational results and efficiencies, following the difficult challenges that Bolivar and Yauricocha have faced over the past two years.

Mr. León is a Peruvian mining engineer with over 25 years of experience and has worked at Sierra Metals since August 2017 in a variety of roles including Director of Operations in Mexico until 2019 and then Country Director in Peru.

Yauricocha and Bolivar are in under-explored and highly prospective geological regions, with an additional 80,000 hectares of virgin properties owned by Sierra Metals. His role is fully aligned with the strategic objective of unlocking the significant potential value of these properties.

Mr. Lujan is a Mexican geological and mining engineer with over 30 years of international experience in mineral exploration with a positive track record for increasing resources, production and company value.
