Originally the site of D. Sieshiltz farm in 1883 when sporadic mining in the area occurred. First description of the original vertical shaft (now backfilled) was by B.L. Miller in 1912. Underlain by a Precambrian hornblende graphite gneiss, the unusual assemblage of mineral deposition at the site can be described as enigmatic at best. (quoted B. L. Miller; 1912, p.114)

Detailed Mineral List:
ⓘ Almandine Formula: Fe2+3Al2(SiO4)3 |
ⓘ Graphite Formula: C |
ⓘ 'Hornblende Root Name Group' Formula: ◻Ca2(Z2+4Z3+)(AlSi7O22)(OH,F,Cl)2 |
ⓘ Magnetite Formula: Fe2+Fe3+2O4 |
ⓘ Pyrite Formula: FeS2 |
ⓘ Pyrrhotite Formula: Fe1-xS |
ⓘ Safflorite Formula: (Co,Ni,Fe)As2 Habit: grains up to 1 cm in size Colour: tin-white metalic Description: in polished section, shows week pleochroism. occasionally occurs in moderatly wide twin lamellae. Safflorite at huffs church has particularly low cobalt content, and it strongly suggests that a Safflorite (fe) species be named to better describe the occurence here. |
