Andrés Restrepo, President and CEO of Mineros, commented "In 2021, we achieved an important milestone for the Company, the completion of a dual listing on the Toronto Stock Exchange ("TSX"), to become the first Colombian-based company to be listed on both the TSX and Colombia Stock Exchange. Despite being new to the TSX, Mineros is a well-established Latin American company with a longstanding commitment to international sustainability standards, and has been a United Nations Global Compact signatory since 2012. The Report is our first sustainability report since listing on the TSX and joining the global marketplace."

"Strong corporate governance and sustainability practices are fundamental pillars for Mineros and they allow us to create value for our stakeholders. Under the direction and supervision of the Corporate Governance and Sustainability Committee, Mineros continues to successfully implement these fundamental pillars. Over the last year we have developed our corporate sustainability strategy and updated our Corporate Sustainability Policy. We continue to be guided by the United Nations Sustainable Development Goals, focused on five key areas: social and economic development, environment, governance, human rights, and health and safety. Mineros will continue face and overcome challenges and has room to both grow and improve, but we are confident that we are following the right path to become a leader in the mining sector with respect to sustainability." Mr. Restrepo continued.
