Nocxite

Nocxite, discovered in YC126 due to new astrogeological surveying techniques, contains mostly nocxium with trace amounts of tritanium and pyerite.
Even trace amounts of nocxite produces intoxicating fumes under atmospheric pressures, demanding special care when being handled planetside. Previous failures to appropriately vent the gasses have resulted in a number of workplace accidents and fatalities.

Nocxite may be found in null security asteroid anomalies.
