When chunks of ore mined out of moons yield above-average densities of Sylvite, the ore is called Brimful Sylvite and reprocessing returns approximately 15% higher quantities of useful material. A ubiquitous ore commercially mined from moons, Sylvite is very useful as it yields good quantities of Evaporite Deposits used as basic elements of some advanced materials. Sylvite ores will also yield Mexallon and Pyerite.
