Gold-silver telluride minerals, and gold ores from Colorado. Arguably, tellurium-rich gold ores are developed in Colorado as well as anywhere on Earth, both in economic terms tonnage of contained gold and in light of the occurrence of diverse well-crystallized mineral species.
Gold Ore is a mineable ore which yields Gold Bars when smelted at a furnace. Each ore can be refined into 10 pixels using a Refinery. It can be found on all planets except barren planets and moons.
Ores that do not contain obvious visible gold or enough to sound off on a metal detector can still be quite valuable and well worth working. Crushing the ore can free the gold and allow recovery by gravity-based methods.

Ore boxes are items that store metal ores. Initially, they can store up to 100 of each ore, increased by 20 for certain ores at certain Mining levels see table below. Completing the Everything Is Oresome achievement 90 Mining required, boostable also increases storage by 20 for all ores, allowing up to 140 to be stored. These two effects are independent of each other.
The gold that these rocks contained has been washed down into creeks to form alluvial placer gold deposits. Here, the gold is further concentrated by the action of water.
