July 2 (UPI) -- A large landslide at a jade mining site in northern Myanmar Thursday killed at least 113 people and left the fate of dozens more unknown, authorities said.
The mining location is 600 miles north of Yangon, Myanmar's largest city. Myanmar produces most of the world's high-quality jade.
Mine waste, or tailings, more than 250 feet high collapsed and poured into an open-pit mine. Many of those trapped in the mine died in muddy water produced by a wave of tailings.
U Kyaw Min, administrator for Wai Khar District, added that he expects more deaths and said additional rain has slowed the rescue work.
"At least 200 will be killed from this," Min said. "We can't go deeper to rescue, so we have to pick up the floating dead bodies. It's also difficult to send the patients to hospitals because the roads are muddy because of the rain."
Freelance miners often work mines looking for jade, but many become unstable during the rainy season. Kachin, which borders China and India, has been a site of tension between Myanmar's military and ethnic fighters.
