The mineral has been already explored in the mine Herzsabánya (today Herja, Romania) at the vein called Makávé but its detailed description was released only in 1925. The fizélyite is a rare silver lead antimony sulphide mineral. It issues during low temperature hydrothermal processes usually in flat, prismatic crystals with metallic light. Its following minerals are semseyite, dolomite, galena, sphalerite etc. Its type locations are Herzsabánya (Herja) in Transylvania and Felsőbánya (Baia Sprie). Beside these places it has been found in Germany, France, Bolivia, Canada, USA.
