Our Values and our Code of Conduct underpin our commitment to establishing and maintaining long-term meaningful relationships with our stakeholders, including governments and employees. The MMG Code of Conduct sets out the standards of behaviour expected from all MMG employees, contractors and suppliers. The Code of Conduct covers areas such as conflict of interest, fraud, anti-corruption and legal compliance.

Matters relating to the Code of Conduct are overseen by the Code of Conduct Committee. We also engage an independent confidential whistleblower service provider, which is available to all employees globally in their local language.

We recognise that some of the jurisdictions in which we work present unique challenges with respect to transparency and individual freedoms. Because of this we seek to match good governance with a commitment to transparency initiatives, such as the Extractive Industries Transparency Initiative (EITI) and the Voluntary Principles on Security and Human Rights (VPSHR).


Due to the declaration of the State of Health Emergency and the National State of Emergency during 2020, we prioritised handling matters related to the pandemic. In 2021, we continue implementing actions to adapt to Law 30424, which regulates the administrative responsibility of legal entities. This model includes the following policies and controls: 

  • Código de Conducta para socios comerciales
  • Cuestionario de diligencia debida para compras de menor cuantía
  • Política de conflicto de intereses
  • Política de interacción con socios comerciales
  • Política de interacción con funcionarios públicos
  • Protocolo de remediación oportuna de riesgos penales
  • Modelos de cláusula anticorrupción y portal de prevención de lavado de activos y financiamiento de terrorismo para socios comerciales y empleados
