This specimen is a pseudomorph - the crystals of tennantite are in the shape of the enargite crystals that initially formed. The large crystals are nearly tablular, as they look like several prismatic crystals formed in parallel. While the overall form of the crystals is that of enargite, there are tiny additional terminations that appear fresh and look like tennantite. There is also a fair amount of brassy pyrite crystals, plus several blades of barite (I believe).
