Compressed Dark Ochre II-Grade

II-Grade dark ochre, also known as onyx ochre, has a distinctive, shiny black surface that lends itself to ornamental uses. But the 5% higher mineral yield is what miners are really after. Like in all else, good looks are only an added bonus. Considered a worthless ore for years, dark ochre was ignored by most miners until improved reprocessing techniques managed to extract the huge amount of Isogen and Mexallon inside it. Dark ochre also contains useful amounts of Nocxium. This material is compressed and a much more compact form of the original material.
