Gold mask found in China

Archaeologists have uncovered a 3,000-year-old gold mask in southwest China. Weighing about 280 grams of 84% gold, the ceremonial mask is one of over 500 items unearthed from six newly discovered "sacrificial pits."

The finds were made at Sanxingdui, a 4.6-square-mile area outside the provincial capital of Chengdu. Experts say the items may shine light on the Shu state, a kingdom that ruled in the western Sichuan basin until 316 BC.
