Work History

Staked by United Keno Hill Mines Ltd as Y cl 1-32 (84090) in Apr/65 following release of Geological Survey of Canada stream sediment data collected during Operation Keno (1964). United Keno performed mapping and grid soil sampling later in the year
Restaked as Brefalt cl 1-24 (YA43539) in Mar/81 by McCrory Holdings Ltd.

Capsule Geology

The area is located approximately 5 km northwest of McQuesten Lake, on the upper right branch of Pointer 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 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 shows that the occurrence area is underlain by schist. Grid soil sampling and prospecting by United Keno Hill Mines failed to uncover any mineralization.
