A landslide near a jade mine in northern Myanmar killed about 100 people, most of them villagers digging for scraps in a towering mountain of displaced earth, a witness and a community leader said Sunday. Many more 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-waste dump also were flattened.

In addition to the dead, he estimated that between 100 and 200 people were missing.

Search and rescue teams wearing bright orange uniforms combed through the rubble for survivors.

Hpakant is around 965 kilometers (600 miles) north of Yangon, Myanmar's biggest city. The region, which borders China, is home to some of the world's highest-quality jade, bringing in billions of dollars a year, though researchers say most of that money goes to individuals and companies tied to Myanmar's former military rulers.

Myanmar only recently started moving from a half-century of dictatorship to democracy.

Hpakant, the epicenter of the country's jade boom, remains desperately poor, with bumpy dirt roads and constant electricity blackouts.

Informal miners risk and often lose their lives picking through scraps at the giant mines.

"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, a group that investigates revenue misuse.

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