Work History
Staked as J cl 1-8 (84246) and cl 9-11(84418) in Apr/65 by United Keno Hill Mines Ltd, which performed soil sampling later in the year.
Restaked as Zap cl 1-32 (Y68457) in Aug/72 by Silver Spring Mines Ltd. The bottom quarter of the Zap claim block overlaid Silver Spring's Dog cl 33-53 (Y56040) staked in Jun/71. Silver Spring entered into a joint venture with Canadian Reserve Oil & Gas Ltd and conducted grid soil sampling, geophysical surveys and bulldozing in 1972 and trenching in 1981. Silver Spring's interests were transferred to Canada Tungsten Mining Corporation Ltd in 1982.
The occurrence now lies within Category A Lands of the First Nation of Na-Cho Nyak Dun.
Capsule Geology
The occurrence area is located at the mid-point between Rambler Creek and Martin Gulch approximately 3 km northeast of Rambler Hill 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. The creeks were also sampled for heavy minerals at this time as part of the Geological Survey of Canada's Operation Keno (1964). C. Roots (1997) of the Geological Survey of Canada remapped topographic map sheet 105 M, located to the immediate south in the 1990's. In 2003 Gordey and Makepeace of the Geological Survey of Canada released a geological compilation which included this area.
Gordey and Makepeace extrapolated Roots geological mapping to produce their geological compilation of the occurrence area. According to their compilation the area is underlain by Middle to Late Devonian Earn Group carbonaceous metasediments and felsic metavolcanics which have been overlain by Early Carboniferous Keno Hill Quartzite. Numerous Triassic age mafic intrusion intrude both units.
The occurrence marks the presumed centre point of a series of weak heavy metal stream sediment anomalies located by the Geological Survey of Canada's Operation Keno (1964). United Keno Hill Mines staked several hundred claims in the region to cover the various anomalies detected by the geochemical survey. Although no records can be found pertaining to the "J" claims, the company generally carried out grid soil sampling and a thorough prospecting program on each claim group. No significant mineralization appears to have been found.
Silver Spring Mines became active in the region in the early 1970's. The company purchased the Lucknow property (Minfile Occurrence #106D 081) located 3 km to the south in Jun/72 which included the Dog claims. The Zap claims appear to have been staked to cover the northern extension of the silver-lead veins found on the Lucknow property. Information on the Zap claims is sketchy but it appears the vein system extended onto the southern end of the claim block but no assays regarding grade can not be located. It seems likely that these veins were the source of the heavy metal stream sediment anomalies.
