Work History
Staked as Arena cl 1-20 (YB77873) in Feb/96 by Expatriate Resouces Ltd., which carried out reconnaissance soil geochemistry, geological mapping, prospecting , and claim surveys later in the year.
Capsule Geology
The occurrence lies within an area recently re-mapped by Murphy et al (2004) of the Yukon Geological Survey. The occurrence occurs in Murphy's Cleaver Lake thrust sheet. Rock in this area exhibit older-over-younger relationships along its full map trace with Devonian and Mississippian rocks overlying lower Permian rocks. The area is located in the hanging wall of the Cleaver Lake thrust and the occurrence area is underlain by massive biotite granite (unit MSg) assigned to the Early Mississippian, Simpson Range Plutonic Suite. The granite extends east to the thrust zone.
The Arena claims are almost completely underlain by massive biotite granite. Biotite-chlorite gneiss probably occurs in the northeast corner of the claim block. Expatriate outlined a weakly to moderately anomalous soil anomaly on the northeast side of the claim block (this occurrence). Soil samples returned copper in soils up to 117 ppm while float samples returned up to 8 070 ppm copper. Mineralization in the float samples was described as up to 15% local pyrite plus chalcopyrite with minor malachite and azurite in granite. It appears that Expatriate planned further exploration to locate the source of the anomaly but economic conditions led to the claims being allowed to lapse.
