  • My Guyana El Dorado – How we get the gold – Guyana

    In Guyana, gold mining is mainly by the open-pit method – which refers to extracting rock or minerals from the earth by their removal from an open pit or borrows. Open-pit mines are dug on benches, which describe vertical levels of the hole. Most walls of the pit are generally dug on an angle less than vertical, to prevent and minimize damage and danger from rock falls. This depends on how
