Minamata Convention ASGM Compliance: What Remediation Partners Need to Understand

How the Minamata Convention frames mercury reduction in artisanal and small-scale gold mining.

June 14, 2026 | 2 min read | By Matt Dunn, Chief Technical Officer

Quick answer: The Minamata Convention treats artisanal and small-scale gold mining as a major mercury source and asks countries with significant activity to reduce and, where feasible, eliminate mercury use. For remediation partners, that means technical solutions must align with national action plans, community realities, reporting needs, and safer livelihood pathways.

The convention is not just a policy headline

The Minamata Convention on Mercury is the global treaty framework for reducing mercury pollution. Article 7 focuses on artisanal and small-scale gold mining because ASGM is deeply tied to mercury use, informal economies, rural livelihoods, and weak infrastructure in many regions.

For companies and project developers, the practical lesson is simple: mercury remediation projects need to fit inside a country-specific compliance pathway. The treaty does not create one universal field method. It encourages national plans, local reduction strategies, and programs that can be implemented in real mining communities.

What ASGM-focused programs usually need

A remediation partner entering an ASGM region should expect to address several categories at once.

  1. Mercury inventory and site diagnosis. Projects need to understand where mercury is used, where it is burned, where tailings are dumped, and where contamination migrates.
  1. Cleaner processing alternatives. Any mercury reduction claim is weak if miners cannot maintain production. Better recovery methods, training, and economics matter.
  1. Exposure reduction. Retorts, containment, ventilation, shop controls, and safer handling can reduce immediate health risk while broader transition work continues.
  1. Environmental restoration. Tailings, sediments, soil, and water systems require protocols that can be monitored after deployment.
  1. Reporting and verification. Governments, funders, and communities need defensible data. Claims have to survive third-party review.

Why technology alone is not enough

Mercury is not used because communities lack concern. It is used because it solves an immediate economic problem. Replacing it requires trust, training, access to equipment, buyer relationships, and local governance. That is why a compliant remediation platform should include community engagement and economic design alongside chemistry and engineering.

What funders should look for

Grant makers, impact investors, and development finance institutions should look for programs that connect field operations to measurable treaty-aligned outcomes. Good signs include transparent sampling plans, clear chain-of-custody procedures, realistic adoption pathways, and a plan for maintaining infrastructure after the first deployment team leaves.

Where GMRWS fits

Global Mercury Recovery & Water Security is positioned around a five-pillar model: mercury capture, water infrastructure, subsurface intelligence, land regeneration, and aquifer protection. That kind of integrated structure is useful because Minamata-aligned work is rarely a single-technology problem. It is a system problem.
