Overview
Since 2020, a mining rush for ionic adsorption clay rare earth elements (REE) in Kachin State, northern Myanmar, has escalated into one of the most serious ESG crises in the global rare earth supply chain. The mines produce heavy rare earths - including dysprosium (Dy), terbium (Tb), and yttrium (Y) - that feed Chinese separation facilities and ultimately reach global magnet manufacturers.
Satellite analysis by Global Witness (2023) documented over 110 square kilometres of forest clearance in just two years across Chipwi and Nant Moo townships. The pace of destruction rivals industrial-scale coal or gold mining in comparable ecosystems.
Environmental Impact
The mining method - heap leaching ionic clays with ammonium sulfate solutions - is inherently leaky. Acid leachate drains directly into Kachin's tributaries of the Irrawaddy River, turning waterways orange-brown. Communities downstream have reported fish kills, destroyed paddy fields, and contaminated drinking water.
Unlike hard-rock REE mines, ionic clay operations require stripping vast areas of topsoil and secondary forest with minimal infrastructure. There is no environmental impact assessment process in the conflict-affected zone, no tailings management, and no site rehabilitation. The land is effectively written off after the extractable REE ore is exhausted.
Social and Human Rights Impact
The mines operate in territory controlled or contested by ethnic armed organisations (EAOs), principally the Kachin Independence Army (KIA) and affiliated militias. "Taxation" of REE exports - in some cases a flat levy per kilogram of material shipped - has become a primary revenue stream for these groups, directly financing ongoing conflict with Myanmar's military junta.
Local Kachin communities have no free, prior and informed consent (FPIC) process. Farmland and ancestral forests are taken without compensation. Workers at the pit sites - many from impoverished border communities - face hazardous conditions, prolonged ammonium sulfate exposure, and no occupational health protections.
Governance and Supply Chain Opacity
Nearly all output is exported to China via unofficial border crossings near Kanpiketi. Chinese trading intermediaries - operating through a layered network of shell companies - purchase concentrate directly, making upstream traceability effectively impossible for downstream buyers.
Myanmar's junta-controlled central government has no effective administrative presence in Kachin. Export licences are either absent or fraudulent. A Chinese government moratorium on imports from the most egregious zones was announced in late 2023 but enforcement has been inconsistent, and production has continued to reach Chinese separation plants.
Supply Chain Implications
Myanmar has become the dominant global source of heavy rare earths - accounting for an estimated 60-70% of global Dy and Tb mine supply at peak. Any Western manufacturer consuming NdFeB magnets containing Dy or Tb faces material exposure to this supply chain unless robust country-of-origin verification is in place.
The Lynas Rare Earths LAMP facility and a handful of non-Chinese projects are the primary certified-clean alternatives, but combined output remains well below demand.
What to Watch
- Chinese regulatory enforcement: Whether Beijing enforces its import moratorium consistently will determine if financial incentives for further expansion persist.
- Western due diligence mandates: The EU Corporate Sustainability Due Diligence Directive (CS3D) and US Uyghur Forced Labor Prevention Act (UFLPA) expansions create legal exposure for downstream buyers.
- KIA peace process: Any substantive ceasefire in Kachin could alter the governance dynamic, though economic dependency on REE revenues may entrench interests in continuation.
