Work History
Staked as Contact cl (84221) by Peso Silver Mines Ltd in Apr/65, following release of Geological Survey of Canada stream sediment data collected during Operation Keno (1964). Peso performed geological mapping and geochemical sampling later in the year.
Restaked as Brefalt cl 1-24 (YA43547) in Mar/81 by McCrory Holdings Ltd.
Capsule Geology
The area is located approximately 6.5 km north of the northern end of McQuesten Lake, on the middle branch of an unnamed creek. 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. Although the area has not yet been remapped by the Yukon Geological Survey, C. Roots (1997) of the Geological Survey of Canada under contract with the Exploration and Geological Services Division (now part of the Yukon Geological Survey) remapped topographic map sheet 105M located directly to the south in the mid-1990's. In 2003 Gordey and Makepeace released a geological compilation of the Yukon which covered this area.
Based on the work of various geologists, the occurrence area is thought to be underlain by a sequence of Middle to Late Devonian Earn Group and Early Carboniferous Keno Hill Quartzite rocks which have been thrust northwest by the Tombstone Thrust onto younger (Upper Proterozoic to Lower Cambrian) Hyland Group clastic rocks.
The occurrence marks the center point of a weak zinc-silver-molybdenum anomaly detected during stream sediment sampling carried out during the Geological Survey of Canada's Operation Keno (1964). Field notes recorded by the sample collection team and geological mapping carried out by Peso Silver Mines shows that the occurrence is underlain by Early Carbonifeous Keno Hill Quartzite. Grid soil sampling by Peso Silver Mines failed to uncover any mineralization.
