A Chinese company digging an unexploited copper mine in Afghanistan has unearthed ancient statues of Buddha in a sprawling 2,600-year-old Buddhist monastery.

Archaeologists are rushing to salvage what they can from a major 7th century B.C. religious site along the famed Silk Road connecting Asia and the Middle East.

The ruins, including the monastery and domed shrines known as ‘stupas,’ will likely be largely destroyed once work at the mine begins.

The ruins were discovered as labourers excavated the site on behalf of the Chinese government-backed China Metallurgical Group Corp, which wants to develop the world’s second largest copper mine, lying beneath the ruins.

Historic find: Ancient Buddha statues inside a temple in Mes Aynak, south of Kabul, Afghanistan. Chinese labourers digging a copper mine made the astonishing discovery
