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.
Available primarily in low security status star systems.
