YANGON, Myanmar (AP) — A landslide near a jade mine in northern Myanmar killed about 100 people, most of them villagers digging for green stones in a mountain of displaced earth, a witness and a community leader said Sunday. Many other people were missing.

The collapse occurred Saturday evening in the Kachin state community of Hpakant, said Brang Seng, a jade businessman, who watched as bodies were pulled from the debris and taken to a hospital morgue.

“People were crying,” he said, adding that some lost loved ones when boulders and earth ripped down the slopes. “I’m hearing that more than 100 people died. In some cases, entire families were lost.”

Lamai Gum Ja, a community leader, said homes at the base of the mine dump had been flattened.

An estimated 100 to 200 people were still missing, he said. Search and rescue teams wearing bright orange uniforms combed through the rubble Sunday for survivors.

Kachin, around 950 kilometers (600 miles) northeast of Yangon, Myanmar’s biggest city, is home to some of the world’s highest-quality jade.

The industry generated an estimated $31 billion last year alone, with most of the wealth going to individuals and companies tied to Myanmar’s former military rulers, according to Global Witness, a group that investigates misuse of resource revenues.

The jade industry’s epicenter, Hpakant, remains desperately poor, with bumpy dirt roads, constant electricity blackouts and sky-high heroin addiction rates.

After Myanmar’s former military rulers handed over power to a nominally civilian government five years ago, resulting in the lifting of many Western sanctions, the already rapid pace of mining turned frenetic. No scrap of ground, no part of daily life in Hpakant is left untouched by the fleets of giant yellow trucks and backhoes that have sliced apart mountains and denuded once-plush landscape.

In the last year, dozens of small-scale miners have been maimed or lost their lives picking through tailing dumps.

“Large companies, many of them owned by families of former generals, army companies, cronies and drug lords, are making tens or hundreds of millions of dollars a year through their plunder of Hpakant,” said Mike Davis of Global Witness.

“Their legacy to local people is a dystopian wasteland in which scores of people at a time are buried alive in landslides,” he said.
