Work History
Staked as Apex claim by J. McCluskey in 1922. Re-staked as Old Chum claim (16157) in May, 1926 by L.B. Erickson.
Capsule Geology
The occurrence area is located at the southern end of Elliott Ridge, between Castle and Elliot Creeks, approximately 38 km due north of McQuesten Lake. 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. C. Roots of the Geological Survey of Canada under contract with the Exploration and Geological Services Division (now part of the Yukon Geological Survey) remapped adjoining topographic map sheets 106D/8 and 106D/7 (East half) in 1990 and topographic map sheet 105M (1997) in the mid-1990's. D. Thorkelson (2000). also under contract with Exploration and Geological Services Division, remapped topographic map sheet 106D/16 to the north as part of a larger bulletin. The work of these geologists was incorporated into a geological compilation of the Yukon released by Gordey and Makepeace of the Geological Survey of Canada in 2003.
Based on the work of these geologists it is believed that the occurrence area is underlain by Lower Proterozoic Gillespie Lake Group dolomite which has been intruded by Middle Proterozoic resistant dark weathering diorite and gabbro sills and dykes assigned to the Hart River Sills. The occurrence consists of a poorly exposed 30 cm wide quartz vein containing chalcopyrite and a little galena cutting diorite. No assays have been reported.
