Work History

The earliest known staking in this area are the single mineral claims Cape (13954) staked in Aug/22 and Banner (15006) staked in July/23. Both claims were staked by H. Noble and were located approximately 2 km southwest of the occurrence location, on the right limit of Dip Creek, down stream fron the northern most intersection of two gulches.
Staked within Ray cl 1-466 (97882) in Jan/66 by Nordex Exploration Ltd. The company carried out a large regional reconnaissance soil and silt sampling program in Aug/66.
Restaked as Pass cl 1-40 (Y45016) in Dec/69 by the Grant Syndicate and later sold to Spur Exploration Ltd.
Restaked within AXS cl 19-54 (YD17577) in Oct/2009 by Western Copper Corporation.

Capsule Geology

The area was regionally mapped in the early 1970's by D. Templeman-Kluit (1974) of the Geological Survey of Canada. S. Johnston of the Canada/Yukon Geoscience Office (now part of the Yukon Geological Survey) and R. Shives of the Geological Survey of Canada (1995) released a geological compilation which covered this area. The geological compilation was constructed and interpreted using geophysical data obtained from airborne multiparameter geophysical surveys flown over the region by the by the Geological Survey of Canada in 1993 and 1994 and by geological mapping conducted by Johnston on adjoining topographic map sheet 115 I/12 in 1992.
Based on Johnston and Shives geological compilation the occurrence is located at the boundary between a large pendant of Devonian to Mississippian carbonaceous and micaceous quartzite with subordinate mica schist and rare marble assigned to the Wolverine Creek Metamorphic suite which survived the intrusion of the enclosing Mid-Cretaceous Dawson Range Batholith. The batholith is comprised of various phases and the occurrence area is underlain by a biotite-hornblende granodiorite phase. The Dip Creek fault which trends northeast-southwest appears to cut through the occurrence and separates the metamorphic rocks from the batholith.
Nordex Exploration includes a notation from the acting Mining Recorder for the Dawson Mining District dated Dec/64 which states that the Banner and Cape claims were likely staked to cover a galena occurrence which were known to occur throughout the area. The company collected silt and soil samples over an area measuring approximately 373 square kilometres. Silt samples were collected on 358 m centres and sampling covered 114 separate streams. Soil samples were collected where ever silt samples were unavailable or were not accessible. Nordex was unable to relocate any of the earlier discovered galena mineralization. The soil and silt sampling carried out in and around the vicinity of the occurrence returned background levels for copper, lead and zinc.
The Pass claims were staked on the west side of the Dip Creek fault and appear to have been underlain by granodiorite assigned to the Dawson Range Batholith.
