All about quarries — Rustafied · Quarry health. Quarries have 2500 health and are pretty resilient to taking damage. It''ll take a ton of whacks or 9 C4 to destroy one of these bad boys. If your quarry gets damaged, you can repair it with a hammer (just like a wall). If your quarry gets destroyed, the loot from the fuel barrels and the hopper will spew on the ground.
