Work History
Staked in 1902 by C.L. Johnson, C. Seagram and I. Sanborn as the Homestake claim (4692), one of six claims staked by the men and the only one to receive significant work. Work completed prior to 1908 consisted of 47.2 m of drifting and surface pitting.
Restaked as the Taslar cl 139-154 (Y61684) in Aug/71 by Taseko Mines Ltd. Restaked as Bob cl 1-22 (Y78789) in May/74 by American Smelting and Refining Company Ltd. The company added Stella cl 1-16 (Y78998) in Jun/74 and carried out geological mapping and a small geochemical survey later in the year.
Restaked as WS cl 197-208 (YC91789) in Aug/2009 by BCGold Corp. These claims are part of a larger block of WS (Minfile Occurrence #115I 007) and other claims BCGold optioned from S. Ryan in Nov/2006.
Capsule Geology
The occurrence area is located on the south side of Merrice Creek approximately 4 km up stream from the Yukon River and approximately 5 km east of Western Copper Corp's Williams Creek property (Minfile Occurrence #115I 008). The area was mapped at 1:250 000 scale by Templeman-Kluit (1984) of the Geological Survey of Canada. In 2003 Gordey and Makepeace, also employed by the Geological Survey of Canada released a geological compilation that covered this area. M. Colpron of the Yukon Geological Survey and J. Ryan of the Geological Survey of Canada (2010) under the auspices of the Edges project (Multiple Metals Northwest Canadian Cordillera), part of National Resources Canada's Geomapping for Energy and Minerals (GEM) program recently carried out geological mapping to the north.
Based on the work of these geologists it appears the occurrence is located at the boundary between Upper Jurassic granodiorite assigned to the Granite Mountain batholith and volcanic rocks assigned by Colpron to the Upper Triassic Semenof formation of the Quesnellia terrane. Mineralization consists of disseminated chalcopyrite and bornite in quartz veins cutting metamorphosed volcanics near the contact with the granodiorite. The veins trend east, dip 50° north, and vary from 0.3 to 1.4 m wide. Surface samples collected on the property assayed from 0.28% copper for average samples to 0.92% copper for high grade ore samples. Both types of samples returned trace amounts of gold and silver.
BCGold has not released any results for this portion of the WS claim block. Their web site hosts a map which displays Mobile Metal Ion (MMI) soil sampling results and a theorized Carmacks Copper Gold trend that crosses the eastern portion of the WS claim block. Thus its likely the company staked this area to cover any the possible northward strike extension of any potential mineralization that may be found along the Carmacks Copper Gold trend.
