Nearly three weeks after the death of 83 workers in a landslide near a village in Tibet, which official Chinese media characterized as a natural disaster, suspicion is rising that it resulted from improper mining activity. The disaster occurred in Zibug, known as dZibug in Tibetan and Sibu in Chinese, in Maldro Gungkar County roughly 63 km northeast of Lhasa. Nearly two hours before sunrise in Tibet on March 29, the landslide roared about three kilometers down the valley, burying workers in a mining camp belonging to Tibet Huatailong Mining Development Ltd., a subsidiary of China Gold International Resource Corp., under 10 stories of rocks and mud. Immediately after the incident, the state-run news agency Xinhua reported that it was a natural disaster and said rescue workers were hopeful of finding workers alive. However, researchers in the United Kingdom and at the Tibet Environment Desk in the exile capital of Dharamsala in India began raising suspicions.
