The ZN showing is located on the eastern shore of the Lower Arm of Duncan Lake, approximately 6.5 kilometres north of Glacier Creekâs mouth.
Regionally, the area lies within the Kootenay Arc near the margins of the Ancestral North American Terrane. The Kootenay Arc is a curving belt of highly deformed metasedimentary and metavolcanic rocks, which includes the Upper Proterozoic Horsethief Creek Group, the Eocambrian Hamill Group, the Lower Cambrian Badshot Formation, and the lower Paleozoic Lardeau Group. The volcano-sedimentary sequence is intruded by numerous Ordovician, Devonian and Mississippian granitoid plutons. The rocks have undergone regional metamorphism to middle or upper greenschist facies.
Locally, an extensive gossanous area over an aggregate strike length of approximately 3 kilometres and a width of nearly 150 metres is exposed along the lake shore.
Between 1991 and 1996, the ZN property was explored by D. Sutherland, including programs in 1993 and 1996 of geological mapping, prospecting, geochemical sampling, geophysical surveys and diamond drilling, totalling 306.01 metres. In 1993, diamond drilling returned up to 238 parts per million copper over 0.90 metre and 173 parts per million copper over 2.73 metres (Assessment Report 23247). In 1996, a diamond drill hole was collared near the contact of the Upper Index Formation and drilled south west into the Lower Index Formation. The upper section of the hole was predominantly carbonaceous to argillaceous limestone with pyrrhotite and minor chalcopyrite mineralization. The lower section of the hole was predominantly cherty material with short sections of short grey tuff. The cherty material is pervasively mineralized with fine disseminated pyrite.
