This old mine has been producing some of the world's finest well-crystallized specimens for over a century. The mine is located close to the small village of Chiuzbaia (formerly Kisbánya), 7 km ENE of Baia Mare. [Note: Geographically, the Herja mine belongs to Baia Mare, but old specimens from Herja mine are usually labelled as Chiuzbaia (Kisbánya).]

According to Cook and Damian (1997), all the lead antimony sulfosalts are As-free.
