According to the Radio Pakistan, the accident occurred due to brake failure at the largest silver mine in the north part of the country.
The accident happened when a bus carrying 50 miners to the underground operation crashed into the side of the tunnel.
The injured have been hospitalised. The Ministry of Emergency Management has sent a working team to guide and assist rescue and investigation at the site while the investigation was underway.
China is the world’s third-largest producer of silver, producing around 2,500 tons of the metal in 2017, a little more than twice what the US produces.
