Work History
Originally staked within GE cl 832-884 (YA68159) in Mar/81 by Shell Canada Resources Ltd on the behalf of George Kent & Associates Ltd following a Mark VI airborne EM survey. The claims were part of a larger block (800+) of GE claims which were staked to cover more than 500 geophysical anomalies identified in the airborne survey. Kerr Addison Mines Ltd optioned the entire claim block in May/82, and carried out geochemical surveys, geological mapping and further geophysics including Shootback EM, VLF-EM, magnetometer and gravity surveys.
The occurrence was restaked as GMS cl 1-21 (YB14058) in Jun/88 by Glimmer Resources Inc which allowed the claims to expire the following year. The company restaked the claims as GMS cl 1-21 (YB15898) in Aug/89 and carried out a Max-Min II EM survey in 1990. The claims covered Kerr Addison's "L" grid.
H. Caesar staked Tom cl 1-2 (YB16318) to the north in Aug/89. Caesar added Luck cl 1-2 (YB16683) in Oct/89. In Oct/93 C. Dickson restaked the Tom and Luck claims as Tom cl 1-4 (YB46367). Dickson transferred a 50% interest in the claims to K. Atkin in Jul/94.
In Oct/95 Minfocus International Inc optioned the GMS claims from Glimmer Resources and staked BJ cl 1-128 (YB69925) to the north. In Dec/95 Minfocus staked Tom cl 1-32 (YB71276) west and south of the GMS claims. The claims extend onto topographic map sheet 105A 02, 03 and 06. In March and Apr/96 the company carried out an exploration program on the Tom and GMS claims, consisting of line cutting, magnetic and EM geophysical surveys followed by a two hole ( 398 m) diamond drill program. In Jul/96 Minfocus carried out a reconnaissance exploration program consisting of soil sampling and several lines of magnetics and EM-VLF geophysics on the northwest portion of the BJ claims.
Capsule Geology
The area has not yet been re-mapped by the Yukon Geology Program. Gordey¿s (1999) digital geology map shows that the area is mostly underlain by Carboniferous and Permian sedimentary and pyroclastic rocks which are assigned to the Anvil Assemblage. The occurrence covers several geophysical anomalies in an overburden-covered area. The nearest outcrops 3 to 4 km away were mapped as Mississippian limestone and clastics, but may be Pennsylvanian to Permian in age (i.e. Murphy and Piercey¿s Campbell Range Succession). Several strong six-channel EM anomalies were outlined by the 1981 airborne survey.
Reconnaissance scale geological mapping completed by Cominco Ltd on the neighboring Holmes claims suggests that the area is underlain by Mississippian metasedimentary rocks, which are in turn overlain by Pennsylvanian to Permian mafic volcanic rocks described as Slide Mountain Terrane. Work by Murphy and Piercey (1999, 2000) suggests that rocks previously believed to represent Slide Mountain Terrane are in fact Campbell Range Succession and represent the culmination of the transition from arc-rifting or back-arc extension to oceanic or back-arc marginal magmatism and sedimentation.
Kerr Addison¿s 1982, 3-line gravity survey, suggested possible fault scarp-type profiles nearly coincident with the EM anomalies. Glimmer Resources¿ 1990 Max-Min II survey delineated a strong (40-50 mho) moderately west-dipping, anomaly at a depth of 46 m.
Minfocus used their geophysics program to relocate several earlier geophysical anomalies including the 1981 EM anomaly and the 1990 Max-Min II anomaly. The company targeted each anomaly with 1 drill hole. The first drill hole GMS 96-1 targeted the EM anomaly and encountered 34 m of overburden followed by 63 m of Tertiary (?) sedimentary and volcanic rocks followed by older andesitic lava to the end of the hole (148 m). Hole GMS 96-2 targeted the 1990 Max-Min II anomaly and encountered 35 m of overburden followed by 95 m of Tertiary (?) sediments, followed by a quartz-chert breccia to the end of the hole (205 m). Neither hole encountered any feature which would adequately explain the conductors identified by geophysics.
Soil sampling on the BJ claims revealed several multi-element spot anomalies associated with either magnetic highs or VLF crossover points.
