Localities

At the El Plomo Mine, Ojojona, Tegucigalpa, Distrito Central, Francisco Morazán Department, Honduras, poughite has been found associated with mandarinoite (HOM).

At the type locality, the Moctezuma mine, Moctezuma, Moctezuma Municipality, Sonora, Mexico, poughite occurs as an alteration product of pyrite in the oxidised zone of the hydrothermal gold-tellurium deposit (HOM).
The first report of the mineral cited two specimens. One specimen from the mine dump was a piece of limonite-stained quartz breccia abundantly coated with drusy crusts and small botryoidal rosettes of poughite, with small amounts of pyrite in corroded grains which were in the process of being altered to limonite. Another specimen was a piece of vein quartz coated along cracks and in vugs with emmonsite and minor limonite, and some corroded pyrite grains. Some of the emmonsite was replaced by a crust of crystals of poughite. Other minerals on the specimen were a uranyl tellurite and crystals of jarosite perched on hairs of emmonsite (AM 53.1075-1080).
