01.11.2021Miners use heavy mining machinery to drill wide steps known as benches, which separate the rock containing gold (ore) from the rock with no economic quantities of gold (waste). Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles.
