Jan 29, 2019 (Therese Pettigrew) - Mineralization consists of pyrite, native gold, and minor molybdenite, and is hosted in volcanoclastic sediments. The unit is up to 2 m wide and can be traced from Moose Lake to Finger Lake, a distance of 3 km. The volcanoclastic metasediment consists of 50% fragments of feldspar porphyry, chert, and altered volcanic rocks, 2 mm to 5 cm in size, which have been stretched up to 15::1 parallel to foliation. The matrix contains sericite, green mica, and tourmaline (Patterson et al., 1984).
