Resource nodes are infinite sources of raw materials that can be mined using the Bedrock Extractor. These nodes are found embedded in bedrock and are indestructible.
To find these nodes, look for Ore Boulders on the surface. They mark a resource node directly below in the bedrock.
Resource nodes exist for several materials, including iron, copper, gold, nickel, platinum, uranium, and even rare gems like diamonds. Mining these nodes requires the drill to reach the bedrock layer.
