The Buckwheat workings started as the Buckwheat Mine and the Southwest Opening, both at the southern end of the Franklin orebody. Subsequently, that portion of the orebody, at the shallow end where the two limbs of the orebody curved around and, vertically, form a "spoon" shaped basin, was excavated as the Buckwheat Pit. This later major working obliterated the two prior workings in total. The Buckwheat Pit incorporated areas intruded by pegmatites and featured major, vertical camptonite igneous dike intrusive bodies plus a veinlike body of vuggy dolomite (the Buckwheat Dolomite) of apparent Paleozoic age. All of these geological features contributed to the diverse mineralogy of this locality. This locality is within the Franklin Mining District. The complete list of mineral species occurring within this district, as well as the official boundaries of the district, can be found under the locality file for "Franklin Mining District."
