It is a medium to low temperature

hydrothermal mineral occurring with quartz, pyrite, sphalerite, galena, bornite, tetrahedrite–tennantite, chalcocite, covellite and baryte.[4] It occurs in the mineral deposits at Butte, Montana, San Juan Mountains, Colorado and at both Bingham Canyon and Tintic, Utah.

Enargite was originally described as a new species from the copper mines of the San Francisco vein,

Junin Department, Peru. The name is from Greek έναργής ("distinct"), in reference to its distinct cleavage.[2][4]

Enargite is related to lazarevicite (named after M. Lazarevic), which has the same chemical formula, but cubic crystalline structure.[5]
