III-Grade or viscous pyroxeres is the secret behind the success of ORE in the early days. ORE has since then moved into more profitable minerals, but viscous pyroxeres and its 10% higher mineral yield still holds a special place in the hearts of all miners dreaming of becoming the next mining moguls of EVE. Pyroxeres is a common ore available in all regions of space. It has fair amounts of Pyerite and Mexallon. This material was compressed using an older process that compressed batches of raw materials into units using a set input quantity. Newer compression technology uses a more flexible one-to-one unit compression system.
