Work History

In Jul/94 Cominco Ltd staked Itch cl 1-84 (YB50105) 1 km to the southwest to cover airborne geophysical targets identified during a regional geophysical program flown in 1994. The company also staked Sel cl 1-17 (YB50088) 4.5 km to the southwest (on the northwest end of Hasselberg Lake) at the same time. The following month the company carried out regional geological mapping, prospecting and limited silt sampling on the Itch claims and contour soil sampling on the Itch and Sel claims.
S. Hearty staked Susie cl 1-4 (YB51512) on the northeast end of Hasselberg Lake in Aug/94 and completed trenching and sampling in 1997.
In 1996, Cominco carried out additional regional geological mapping and prospecting programs on the Itch claims and geological mapping, contour soil sampling and HLEM and magnetometer geophysical programs on the Sel claims.
Staked as Itch cl 85-126 (YB88933) in Mar/97 by Cominco to cover an airborne electromagnetic/magnetic anomaly originally identified in 1994. The company carried out line cutting, grid and contour soil sampling and a ground HLEM and magnetometer geophysical survey later in the year.
S. Hearty restaked the Susie claims as Susie cl 1-4 (YB93140) in Aug/2000. In Jul/2001 Hearty carried out prospecting, and rock, heavy mineral and soil sampling on the claims. In Aug/2001 Hearty staked Packsack cl 1-8 (YB93387) on the northwest end of Hasselberg Lake, overtop portions of the expired Sel claims.

Capsule Geology

The area is located southeast of the Finlayson Lake massive sulphide district of southeastern Yukon. The area was last mapped by H. Gabriel (1967), who mapped the Watson Lake map sheet (topographic map sheet 105A) at 1:25 000 scale for the Geological Survey of Canada. The Yukon Geological Survey has not yet re-mapped the occurrence area, however Murphy and others have carried out varying amounts of geological field work on adjoining topographic map sheets 105H/3, 4, 5 and 105G/1 and 2. In 2004, Murphy published a compilation report summarizing results obtained from this work. Comparing Murphy¿s results with the Yukon Geology compilation published by Gordey and Makepeace in 2003 allows one to reasonably predict the geology underlying the occurrence area.
The area is located within the Big Campbell thrust sheet, one of several fault- and unconformity-bound metasedimentary and metavolcanic successions and affiliated metaplutonic suites proposed by Murphy (2004) for the Finlayson Lake massive sulphide district of the Yukon- Tanana Terrane. The Big Campbell thrust sheet contains the structurally deepest rocks and those that host the majority of the volcanic hosted massive sulphide (VHMS) deposits of the district. It is bound below by the Big Campbell thrust, and above by the Money Creek thrust.
The occurrence area hosts the same stratigraphic units that occur in the core of the Finlayson Lake massive sulphide district. Based on geological mapping completed to the north, the oldest rocks are likely quartz-rich psammite (meta-sandstone), meta-pelite and marble of the pre-Upper Devonian North River formation. The North River formation is overlain by the Fire Lake formation, which consists primarily of chloritic phyllite or schist, and lesser carbonaceous phyllite or schist, and muscovite-quartz phyllite or schist of felsic volcanic protolith. As in the Finlayson Lake massive sulphide district, mafic and variably serpentinized ultramafic metaplutonic rocks are spatially associated with the Fire Lake formation. To the north the metaplutonic rocks form a several hundred-metre- thick sheet within the upper part of the formation. It is likely that the succession is intruded by one or more small mid-Cretaceous granitic intrusions.
Cominco reported generally poor outcrop exposure on the Itch claim block due to extensive glacial deposits. The best exposures were located in creeks along the west side of the property. These exposures consist of grey to black, variably carbonaceous mudstone and silty mudstone with minor interbedded quartzite and siltstone (likely North River and/or Fire Lake formations). Similar lithologies are reported west of the Sel property, but no exposures were noted on that claim block.
Contour soil samples were collected over both claim blocks in 1994 and followed up with grid soil sampling in 1996 and 1997. Two minor Ag anomalies, one with supporting As values were detected on the Sel claims. No anomalous values of interest were returned from samples collected on the Itch claims.
Ground geophysical surveys completed in 1996 and 1997 on the Itch and Sel claim blocks targeted conductors identified in the 1994 airborne geophysical survey. On the Sel claims the surveys identified several conductors and magnetic features, none of which were coincident. A linear magnetic anomaly with a flanking conductor was identified on the Itch claims (the occurrence location), but Cominco judged its conductivity too weak and its strike length too short to be of economic interest.
Hearty originally staked the Susie claims as a source of jade boulders. Prospecting and rock, heavy mineral and soil sampling uncovered anomalous gold values in glacial till on Susie claims 1 and 2 located beside Hearty Creek.
