"This is no regular bore. This is Deep Bore. If it were Shallow Bore, they would call it "ditch" or something."

Deep Bores are the tier 5 resource in the Ore industry.

If no discounts are applied, one deep bore costs 1 M Mines, 10 II Ore, and 3 Comrades.

It produces mines and is produced by Oil Rigs. It takes 1 minute and 4 seconds to complete a cycle.
