An automated mining system for hauling raw metal out of the ground.

–In-game description

For some reason all 3 levels of ore drill are unlocked by Automated Ore Mines tech. This may be a bug as of .93.4. Future releases may have multiple levels of tech to unlock higher drill levels.

[0.98.35] Ore Drill is not upgradable to Ore Drill II even with the research.

Efficiency and rate ore is gathered depends on where the drill is built. Prospecting should be used to find the best placement.
