Safflorite is a rare gray metallic mineral forming prismatic to radially fibrous crystals in hydrothermal veins. It is characteristically associated with minerals bearing cobalt, nickel or arsenic such as cobaltite and arsenopyrite.

LAFAYETTE COUNTY: Safflorite is reported as a rare primary mineral in the zinc-lead ore bodies of the Belmont and Calamine Districts (Klemic and West, 1964).
