Silvery Omber was first discovered some fifty years ago in an asteroid belt close to a large moon. The luminescence from the moon made this uncommon cousin of normal Omber seem silvery in appearance, hence the name.
Omber is a common ore that is still an excellent ore for novice miners as it has a sizeable portion of isogen, as well as some tritanium and pyerite. A few trips of mining this and a novice is quick to rise in status. 500 ore units are needed for refining.
