Work History
Discovered by British Yukon Exploration Company Ltd about 1956 and first staked as Fran cl 1-16 (80207) by R. McKamey in Jul/57. These claims were examined by Canex Aerial Exploration Limited but no record of any work can be found.
Capsule Geology
The occurrence is located on the east side of the Wind River, approximately 3km northeast of Angel Lake in north-central Yukon. L.H. Green of the Geological Survey of Canada mapped the area at 1:250 000 scale 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 adjoining 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.
Information on this occurrence is sketchy. Previous versions on Yukon Minfile reported a 5.5 m bed of specular hematite in argillite (mudstone ?) at this location. Green assigned a Precambrian age to rocks in the area while Thorkelson revised the age to Lower Paleozoic (Cambrian to Devonian). According to Thorkelson the mudstone likely represents part of the lowest strata of the unit and he tentatively correlated it with the Middle Cambrian Slats Creek Formation.
Adding to the confusion is the Yukon Mineral Industry Report for 1957 which reported that McKamey staked his claims to cover copper mineralization. Green (1964) reported that hematite mineralization found in this area sparked a small staking rush in 1958. It is quite possible the claims were originally staked to cover minor copper mineralization known to occur throughout the area but that the discovery of specular hematite changed the focus of exploration. More recent investigations have been unable to locate the showing.
