Work History
Staked as Newt cl 1-18 (Y95860) in Aug/74 and cl 19-26 (Y96751) in Sep/74 by Dynasty Explorations Ltd.
Capsule Geology
The occurrence area is located on the western peak of Castle Mountain approximately 8 km northeast of Elliot Lake in north-central Yukon. 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 of the Geological Survey of Canada under contract with Exploration and Geological Services Division (now part of the Yukon Geological Survey) remapped topographic map sheets 106D/8 and 106D/7 (east half) to the southeast in 1990. D. Thorkelson (2000) also under contract with Exploration and Geological Services Division remapped topographic map sheet 106D/16 to the northeast 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 Ordovician and Silurian carbonate rocks. Little is known about this occurrence and no assessment work records can be located. The Northern Cordillera Mineral Inventory, a precursor to the Yukon Minfile database reports that the occurrence consists of galena and sphalerite mineralization hosted by breccia zones which cut Ordovician carbonate rocks.
