Golden Omber spurred one of the largest gold rushes in the early days of space faring, when isogen was the king of minerals. The 10% extra yield it offers over common Omber was all it took to make it the most sought after ore for a few years.
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.
This ore is a compressed and much more dense version of the original ore.
