At least 36 bodies have been recovered from a landslide in Tibet, state media report, after dozens of miners were buried on Friday.
Thousands of workers continued to dig over the weekend for those thought to be buried under tonnes of mud, rock and other debris.
The disaster area is 4,600m (15,000ft) above sea level, 70km (45 miles) east from the Tibetan capital, Lhasa.
Some rescuers had to be treated for altitude sickness, an official said.
The landslide took place at 06:00 local time on Friday (22:00 GMT on Thursday), burying 83 miners.
Rescuers were only able to find the first body 36 hours after the disaster. Most of the others were recovered on Sunday.
One worker told China National Radio that they would continue to search "as long as there was a 1% chance" of finding bodies.
As well as altitude, the teams are also battling freezing weather and the risk of further landslides.
"There are cracks on the mountaintop and secondary disasters are possible," Jiang Yi, a police officer, was quoted by state-run news agency Xinhua as saying on Sunday.
The miners were working for a gold mine subsidiary of the state-owned China National Gold Group, the country's largest gold producer.
Most of the workers were ethnic Han Chinese from Yunnan, Guizhou and Sichuan provinces, with two reported to be ethnic Tibetans.
Meanwhile, six people have died and 11 others are missing after a gas explosion at a coal mine in Jilin province, Xinhua says.
Three days ago, 28 miners also died at the mine after an explosion.
