In 2025, Las Bambas advanced its first standalone Human Rights Impact Assessment (HRIA), a foundational input to MMG’s ongoing human rights due diligence.
We place individuals, their rights and their lived experiences at the centre of risk identification.
By engaging an independent business and human rights consultant to conduct the HRIA in line with international standards ,with oversight from MMG’s Independent Human Rights Advisory Group (HRAG), the HRIA was designed to be credible and robust process to identify and understand human rights risks and impacts.
Las Bambas operates in a socially complex environment that includes remote geography, diverse Indigenous communities, longstanding development challenges and in many areas, limited access to public services. Reflecting this context and MMG’s risk-based approach to prioritisation, Las Bambas was selected as the site of MMG’s first HRIA.
The assessment provides a structured way to understand how our operations affect people and supports more transparent and consistent engagement. It supports more transparent and consistent engagement, supports our ongoing engagement with stakeholders, and enables more informed decision-making in a challenging operating environment.
The HRIA applied an internationally recognised methodology aligned with the UN Guiding Principles on Business and Human Rights and Danish Institute for Human Rights frameworksfocusing on identifying potential and actual harm to people (including communities, employees, and contractors), recognising positive impacts only insofar as they prevent, mitigate, or remedy harm.
The process involved a review of internal company documents, such as policies, procedures and risk assessments. The engagement phase involved interviews and group discussions with potentially impacted communities and were conducted in Quechua and Spanish. Direct employees, contractors and community-based contractor companies were also engaged to better understand workplace-related risks and practices.
To increase rigor and credibility, the HRAG, composed of experts with deep experience in human rights issues in the sector and region, provided independent guidance and oversight of the HRIA process. The findings and recommendations from the HRIA were tested and refined with the input of the HRAG.
The HRIA has given Las Bambas, and MMG more broadly, a clearer, evidence-based understanding of the human rights risks and impacts associated with our operations, as seen by our workers, contractors and host communities.
The findings identify the salient issues that reflect the operational realities of a large-scale mining operation and the socio-economic context of the region. The salient issues and the associated recommendations will be prioritised in a human rights action plan and integrated into our broader risk management processes. A number of actions require engagement with third parties, including government actors and others operating in the area, where Las Bambas will seek to build and exercise leverage.
The Committee’s action plan will be implemented and tracked including, progress reported to MMG’s Board through established governance channels. Maintaining transparent communication and ongoing engagementwith affected rightsholders and broader stakeholders will also be embedded in the action plan to strengthen accountability and trust.
The HRIA has also informed MMG’s broader group-wide salient human rights issues assessment, helping to align site-level findings with a consistent group-wide view of where our most significant risks to people sit and where our efforts should be focused.
