Work History
United Keno Hill Mines Ltd staked 72 W claims (1 = 84142) in Mar/65 but five claims were refused leaving 68 non sequentially numbered claims being registered. The company carried out prospecting and grid soil sampling over the western end of the claim block later in the summer.
Capsule Geology
The occurrence area is located approximately 8 km southeast of Mount Patterson and surrounds an unnamed creek which flows southeast into the Laduc River. 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 creek was also sampled for heavy minerals at this time as part of the Geological Survey of Canada's Operation Keno (1964). G. Abbott (1990) employed by Indian and Northern Affair's Exploration and Geological Services Division, Yukon Region (now part of the Yukon Geological Service) remapped topographic map sheet 106D 01 at 1:50 000 scale and C. Roots (1997) of the Geological Survey of Canada remapped adjoining topographic map sheet 105 M in the 1990's. Atna Resources Ltd (Holbek, et.al. 2001) majority owner (at that time) of the Marg deposit (Minfile Occurrence #106D 009) located approximately 4 km to the south released a detail geological map of the area which included this occurrence. Gordey and Makepeace (2003) released a geological compilation which included this area.
The area is mainly underlain by a sequence of metasedimentary and metavolcanic rocks assigned to Middle to Late Devonian Earn Group and a carbonate package assigned to the Lower Carboniferous Keno Hill Quartzite. At the southern end of the occurrence area a section of the Tombstone Thrust is theorized to cut across the area thrusting Upper Proterozoic to Early Cambrian Hyland Group metasedimenary rocks onto the Earn Group and Keno Hill Quartzite rocks. The presence of the Hyland Group rocks are argumentative. Abbott mapped them as being Devonian to Mississippian but Atna Resources geologists argue that the presence of blue quartz grains in the rocks, not observed in any of the overlying rocks and a description that matches the description of the Hyland Group rocks provided by Gordey (1990) for topographic map sheet 105M 16 located directly to the south, suggests that these rocks are older. Numerous Triassic mafic intrusions intrude the entire occurrence area.
United Keno Hill Mines carried out an extensive prospecting and grid soil sampling program in an attempt to determine the source of several anomalous heavy metal anomalies (highest = 325 ppm). Prospecting did not find any mineralization in place or as float. Soil sampling uncovered two small lead anomalies (highest = 1 600 ppm) with corresponding copper and zinc values. The area is known to have unusually high zinc background values which United Keno Hills interpreted to be the cause of the heavy metal anomalies found by the Geological Survey of Canada.
