Stibiogoldfieldite is a new mineral, approved in 2020.


At the Pefka mine, Pefka, Alexandroupoli, Evros, Eastern Macedonia and Thrace, Greece, stibiogoldfieldite was reported in 2022. The deposit is an epithermal high-sulphidation type gold mineralisation hosted in felsic volcanic rocks such as dacite and rhyodacite. The mineralisation is hosted by andesitic lavas and is unusually enriched in indium, tellurium, selenium and copper (Mindat).

At the type locality, the Mohawk Mine, Goldfield, Goldfield Mining District, Esmeralda County, Nevada, USA, stibiogoldfieldite occurs as metallic anhedral grains, dark grey in colour. It is associated with quartz, pyrite and a silver-bismuth-(sulphur, selenium) phase (holotype material) and with quartz, pyrite, calaverite, bismuthinite, bohdanowiczite, and the silver-bismuth-(sulphur, selenium) phase (cotype material).
The Goldfield mining district belongs to a series of large epithermal precious metal ore deposits hosted in hydrothermally altered volcanic rocks (MM 86.1.168-175).
