After the locality, the Alaska Mine, Colorado, USA
Originally described from Alaska mine, Poughkeepsie Gulch, Silverton District, San Juan Co., Colorado, USA.
A study of different samples led Thompson (1950) to conclude that "that previous workers were dealing with non-homogeneous material which consisted of such minerals as matildite, aikinite, benajminite, tetrahedrite, with chalcopyrite, sphalerite, pyrite, and galena."
Not to be confused with the rock alaskite.
