Jalpaite is a rare copper silver sulfide mineral with formula Ag 3 CuS 2.. It was first described in 1858 for an occurrence in the Leonora Mine, Jalpa, Zacatecas, Mexico and named for the locality. It occurs in low temperature hydrothermal veins at temperatures less than 117 °C (243 °F). Associated minerals include acanthite, mckinstryite, galena, sphalerite, pyrite, chalcopyrite ...

Rare Jalpaite, a silver copper sulfide, as grey metallic masses in matrix with native Silver. Excellent specimen.
Jalpaite can be identified in the field by its gray and dark gray variations and opaque quality. This mineral has metallic lustre with black streak. The density of jalpaite is 6.82 g/cm 3 with a hardness of 2-2.5 – between gypsum and finger nail. The fractures occurring in this mineral are like curved shavings produced by a knife.
Jalpaite (SXRD-analysed) as aggregates of dark grey, short prismatic, ductile crystals on quartz. Found by Richard Bayerl in August 2013. The matrix of the specimen consists of quartz, colourless fluorite and much strongly covellinised chalcopyrite.
