As a mine moves from open pit to underground, it's likely for the volume and grade of ore to change. This has implications for the mine infrastructure. "You need to consider the impact on processing," adds Bell. "A bulk open pit operation is likely to produce more tons of lower grade ore compared to an underground mine."
