    Abstract

    The Golden Zone (-149.6397222,63.2188889) is a 9,900 hectare Au–Cu-Ag mining claim located in the Chulitna mineral belt of the Valdez Creek mining district in south-central Alaska, approximately 240km north of Anchorage. It is bordered on the north and west by the mountainous Denali Wilderness Area, which is off limits to mining and an environmentally sensitive area. The Golden Zone property lies at the northern end of the Chulitna-Yentna mineral belt, a fault-bounded block of Devonian to Triassic sediments and volcanoclastic sediments (Hedderly-Smith,2011)
