In Myanmar, illicit rare-earth mining is taking a heavy toll
In early 2025, Sian traveled deep into the mountains of Shan State, on Myanmar's eastern border with China, in search of work. He had heard from a friend that Chinese companies were recruiting at new rare-earth mining sites in territory administered by the United Wa State Army, Myanmar's most powerful ethnic armed group, and that workers could earn upwards of $1,400 a month.
It was an opportunity too good to pass up in a country where the formal economy has collapsed since the 2021 military coup, andnearly halfof the population lives on less than $2 a day. So Sian set off by car for the town of Mong Pawk, then rode a motorbike for hours through the thick forest.
Hired for daily wages of approximately $21, he now digs boreholes and installs pipes. It is the first step in aprocesscalledin situleaching, which involves injecting acidic solutions into mountainsides, then collecting the drained solution in plastic-lined pools where solids, like dysprosium and terbium, two of the world's most sought-after heavy rare-earth metals, settle out. The resulting sediment sludge is then transported to furnaces and burned, producing dry rare earth oxides.
