Ore
Ore is a resource added in 1.0. It is obtained by mining. It's the only resource which is by default not loaded into the containers.
Mining
Ore is generated by mining planets or asteroids using the 'Drill-O-Matic' Mining Excavator. Drilling continues to function during time warp.
Planets
Ore is found on the solid surface of all planetary bodies, thus excluding Kerbol, Jool, and in water biomes.
The average level of Ore in a particular biome can be detected using a M4435 Narrow-Band Scanner. A more precise determination for a particular location can be made using the Surface Scanning Module while landed.
Asteroids
Asteroids contain a finite amount of ore. If mining an asteroid, the mass of the asteroid will be reduced by the amount of ore extracted.
Storage
Ore is stored in special containers, the Large Holding Tank and Small Holding Tank.
Conversion into Other Resources
Ore can be converted into liquid fuel, oxidizer, and monopropellant using the ISRU Converter and electric charge. There is no change in total mass when converting to liquid fuel and/or oxidizer, but there is when converting to monopropellant. Conversion continues to function during time warp.
