Two persons have been confirmed dead in the process of mining for a precious stone called Tourmaline.
Newsmen learnt that the incident happened at Shikpeshe, along Buya Road in Obanliku local government area of Cross River State two days ago.
The boys were said to have suffocated to death inside the deep mining well.
Three surviving victims, who were seriously injured, are receiving treatment in a nearby health facility.
Findings showed that some explorers reportedly discovered the Tourmaline and engaged the local youths to exploit it for them.
According to the locals, the boys have spent over four months digging the well which has gone very deep.
Reacting, Governor Bassey Otu prayed for the repose of the souls of the deceased, even as he admonished youths against unwarranted and dangerous ventures capable of threatening their lives.
Speaking through the Commissioner for Mineral Resources, Effiom-Ekaha Otu described the incident as unfortunate and a colossal loss to the state and the family.
He promised a comprehensive investigation into the incident, as well as determining the legality of the mining activity.
