Minerals Due Diligence

Mining is an intensive process involving potential social and environmental risks that, if not properly managed, can cause lasting negative impacts. A growing body of research suggests that these risks are associated with a variety of metals and minerals that extend beyond tin, tungsten, tantalum and gold (3TG). Governments, non-governmental organizations (NGOs), investors, customers and other industry stakeholders have increasing expectations on the private sector to drive responsible behavior deep into their supply chains.

What We Do

The Responsible Minerals Initiative seeks to promote the common goal of understanding and contributing to mitigating the salient social and environmental impacts of extraction and processing of minerals in supply chains, leveraging direct and indirect partnerships and using international standards such as the United Nations Guiding Principles on Business and Human Rights or the OECD Due Diligence Guidance as our guideposts. Together as an industry, and working with all stakeholders, we believe we can make a difference and help companies meet expectations of current and future market, legal and regulatory instruments.

The RMI provides tools and resources to help companies make sourcing decisions that improve regulatory compliance and support responsible sourcing globally, so that minerals supply chains contribute positively to social economic development. Working with participating companies and cross-sector partners, we seek to advance select initiatives to drive meaningful improvement in the mining sector. Throughout this ongoing process, the RMI serves as the voice of progressive industry for responsible mineral sourcing broadly and convenes stakeholders to continually shape and evolve dialogue and practices.
