The company was incorporated in Ontario, Canada and had its corporate offices in Calumet, Michigan. The company had operations in Massey, Ontario, Canada. The Hermina Mine consists of two shafts about 1700 metres apart. The main shaft (#2) was reportedly sunk on a "quartz vein" up to 9 metres wide mineralized with chalcopyrite. The "vein" contains many wallrock clasts and is associated with hematite, chlorite and silica alteration of the enclosing granite. The # 1 shaft is located about 1.5 km west of the Massey adit zone workings. Recent sampling of dump material at the #3 and # 1 shaft areas returned gold values of up to 1.88 g/t Au and 9.56 g/t Au respectively. The Hermina Mine appears to be located on a splay of the Murray fault with its confluence near the Massey Mine and it may be related to geological events in this area.
