"A Crystal Mine is a building that mines raw crystals. Crystals are one of the three basic resources that all emerging and established empires require for the manufacture of electrical circuits. Crystal mines supply the main resource used to produce electronic circuits and form certain alloy compounds. Mining crystal consumes some one and half times more energy than a mining metal, making crystal more valuable. Almost all ships and all buildings require crystal. Most crystals required to build spaceships, however, are very rare, and like metal can only be found at a certain depth. Therefore, building mines in deeper strata will increase the amount of crystal produced. \n* Available from the start \n* N/A"@en . "Crystal mine"@en .
