Sierra Metals Inc.

🚧 On the Road to Critical Control Management 🚧 At Sierra Metals Inc., we believe that safety is not just a value — it's a mindset. As part of our ongoing transformation toward safer and more sustainable mining, we are shifting our approach from reactive incident management to proactive critical risk control. In his latest article, our VP of Health & Safety, Astolfo Segundo Romero Sanchez, explores how our Critical Risk Management Program is helping us move beyond traditional safety practices. By focusing on the controls that prevent or mitigate fatal and catastrophic events, and leveraging real-time digital monitoring, automation, and predictive data, we are building safer workplaces across our operations in Peru and Mexico. 📰 Special thanks to Revista Stakeholders for featuring this article and helping amplify the importance of safety leadership in mining. We invite you to read the full article and learn how we’re building a culture of safety leadership, driving progress toward our goal of zero harm. 👉 https://shorturl.at/M0C3C #United for #sustainablemining, let’s lead with safety—together. #SierraMetals #CriticalControlManagement #ZeroHarm #SustainableMining #MiningInnovation #SafetyLeadership #DigitalTransformation #HealthAndSafety #MiningIndustry

🎥💙 Mother’s Day at Sierra Metals Inc. For this Mother’s Day, we asked our team a simple but powerful question: “What do you feel when your mom tells you she’s proud of you and your work?” The answers speak for themselves: emotion, gratitude, strength, and above all, a deep sense of purpose. At Sierra Metals, we believe pride goes both ways. Our people take pride in their work, and their families (especially their mothers) feel that pride too, knowing their loved ones are part of a company that values safety, responsibility, and human connection. To every mother who has ever said "I'm proud of you": thank you. Those words stay with us and drive us forward. 💐 Happy Mother’s Day from all of us at Sierra Metals Inc. #United for #sustainablemining, let’s lead with our hearts 💕 —together. #MothersDay #SierraMetals #ProudMoms #MiningWithPurpose #PeopleOfSierra

At Sierra Metals Inc. we are proud to have taken part in proEXPLO 2025, one of the most important technical events for the exploration 🧭 sector in Latin America.

This participation reflects our commitment to innovation, talent development and continuous improvement across all stages of the mining lifecycle.

🎥 Today, on the World Day for Safety and Health at Work, we share this video that captures a value at the heart of everything we do 👇 Health and Safety are non-negotiable. They are on of our core values and the foundation of our present and our future. At Sierra Metals Inc., we believe that working safely means working with respect, responsibility, and long-term vision. Safety is much more than procedures and regulations: it is a culture built every day, through every task, every decision, and every conversation. 👷♂️👷♀️ Every person in our organization is a leader in safety. Because taking care of ourselves, our teams, and our environment is not just about compliance — it’s about leadership, commitment, and humanity. As Astolfo Segundo Romero Sanchez, VP of Safety at Sierra Metals, reminds us: "At Sierra Metals, we are strengthening our commitment through the Critical Risk Management Program, focused on identifying, controlling, and eliminating high-risk exposures to protect our people and ensure safe operations every day." True operational excellence is only possible when we prioritize the well-being of our people. There is no production without protection. There is no success without care. Today, we reaffirm our commitment to responsible, safe, and sustainable mining — where every voice, every action, and every improvement matters. Thank you to everyone who makes safety a conviction, not an obligation. #WorldDayForSafetyAndHealthAtWork #SafetyAndHealth #SafetyFirst #ResponsibleMining #SafetyCulture #Sustainability

🌱✨ Young talent as a driver of transformation ✨🌱 At Sierra Metals Inc. we are proud to share the participation of our VP of Talent and Culture, Alberto Calle, at the “Shaping the Future with Innovation and Talent” conference by Australia Peru Chamber of Commerce - APCCI (Oficial), where he spoke about the critical role of young talent in transforming the mining industry. "We believe the future of mining isn’t built by technology alone—but by people", said Alberto. "We look for young professionals who combine technical skills with adaptability, a sustainability mindset, and the drive to make a real impact. To thrive, they need mentorship, stimulating projects, and a clear sense of purpose." 💡 As he shared with the audience, Alberto highlighted some of the challenges our industry faces, including the disconnect between young professionals and mining, and how we can bridge that gap through innovation, sustainability, and meaningful opportunities. If you're a young professional, we invite you to look at mining with fresh eyes. And if you’re already part of the industry, remember: innovation starts with people. #United for #sustainablemining, let’s lead with innovation—together. #SierraMetals #SustainableMining #YoungTalent #Innovation #PurposeDriven #FutureOfMining #MiningWithPeople
