Sierra Metals Updates on Yauricocha Mine Mudslide and Safety Measures

Canadian mining company Sierra Metals reported a tragic incident at the Yauricocha polymetallic mine in Peru, where a mudslide occurred in the underground workings. The company confirmed that three contractor workers were killed and one person was injured as a result of the incident. The event prompted immediate caution and a pause in operations as safety teams assessed the scene and ensured proper security measures before any further activity could resume. The company extended its deepest sympathies to the families, friends, and colleagues affected by this loss, and it indicated that investigations would be conducted to determine the exact causes and assign accountability where appropriate. The statement underscored the seriousness with which Sierra Metals treats mine safety and its commitment to a thorough review of the site conditions and procedures in place at the time of the mudslide. This would also involve coordination with local authorities to support the inquiry and identify preventive measures for the future, as part of ongoing safety improvements within the broader mining operations. According to the company’s disclosure and to sources familiar with the matter, the Yauricocha mine remains a focal point of Sierra Metals’ mining portfolio in Peru, representing a significant portion of its polymetallic output. The site is located near Yauyos, at a considerable distance from Lima, and it operates under the governance of the Corona Mining Association, in which Sierra Metals holds a controlling stake. The association’s leadership and site management are expected to provide updates as the investigation progresses and as the company implements any necessary corrective actions to protect workers. In the wake of the incident, local authorities are expected to carry out their own inquiries, and Sierra Metals has committed to cooperating fully to ensure all safety standards are reviewed and all appropriate measures are taken to prevent a recurrence. This event highlights the ongoing challenges and responsibilities faced by mining firms that operate in Peru and across the North American corridor, where regulatory oversight and worker safety remain top priorities for industry stakeholders. The board and management of Sierra Metals acknowledge the profound impact on the families and crews involved and reiterate their support for those affected while the company works through the incident with the relevant authorities. – Attribution: Sierra Metals press release and subsequent updates from the Corona Mining Association.
