Work History
Reported by the Geological Survey of Canada and staked as Pad cl 1-16 (Yl4707) in May/68 by New Jersey Zinc Exploration (Company) Ltd, which prospected later in the year.
Capsule Geology
The occurrence is located on an unnamed creek situated on the southwest branch of the Bear River, approximately 2.5 km south of the Bear River airstrip. The area was regionally mapped by L. Green (1972) of the Geological Survey of Canada in 1961 as part of a helicopter-supported party known as Operation Ogilvie. D. Thorkelson (2000) a geologist with the Canada/Yukon Geoscience Office (now part of the Yukon Geological Survey), remapped topographic map sheet 106D/16 in the 1990's as part of a larger bulletin on the Wernecke Mountains. Gordey and Makepeace of the Geological Survey of Canada, released an updated geological compilation of the Yukon in 2003.
During the course of field work relating to mass-wasting effects in selected areas of the Ogilvie and Wernecke Mountains, J.T. Gray of the Geological Survey of Canada noted chalcopyrite, azurite and malachite mineralization on joint surfaces at a single site at this occurrence location. According to Thorkelson the area is underlain by argillite of the Lower Proterozoic Quartet Group, and orange dolomite of the Lower Proterozoic Gillespie Lake Group. Both units are members of the larger Wernecke Supergroup. No exploration results can be found related to the prospecting program carried out by New Jersey Zinc.
