Ores are underground deposits of useful materials which, when mined with a Pickaxe, will yield large amounts of a resource. Current ores available are Copper, Iron, Zinc, Silver, Petroleum, Aluminum, Coal and Gold. Diamond ore is not yet implemented. The resources taken from these ores are used in a wide variety of replicator recipes, and can be placed in the world as solid blocks.
Ores can be detected by using the ELMIN scanner, available as a function of the handheld PC. Ores appear as white points beneath the terrain overlay, enabling the player to quickly and efficiently mine them.
Tin is found in small quantities in Copper ore veins and has no scanner detection of its own. Graphite can also be found while mining (around Marble). Steel cannot be mined, it is made by combining Iron with Wood in the Replicator. Sulfur and Sulfate are found when digging up surface Dirt Block.
