Introduction. Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in ...

In Guyana, gold mining is mainly by the openpit method which refers to extracting rock or minerals from the earth by their removal from an open pit or borrows. Openpit 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 ...

gold mining has expanded and is now thought to account for a third of total gold production in the Sahel—and this is in a region with a long history of industrial gold mining (ICG, 2019). The gold mining sector in the region is still largely informal and comprised of diverse actors playing different roles, most of whom are artisanal miners.
