|Location and accuracy||These two unnamed prospects cover about 1 square mile and are situated on the northwest bank of the Kantishna River about 5 miles east of Bearpaw Mountain (KH001). The approximate center of the prospect area is in SW1/4SE1/4 section 35, T. 9 S., R. 17 W. The Kantishna River provides access to the prospects, and there is an airstrip at Lake Minchumina approximately 40 miles southwest. The unnamed prospects are located on land selected by or conveyed to Doyon, Limited.|
The bedrock in the area is Ordovician to Silurian siltstone, mudstone, argillite, grit, quartzite, and limestone, and minor amounts of chert and schist (Chapman and Yeend, 1981). Regionally, the area contains a system of northeast-trending strike-slip and related conjugate faults associated with Cretaceous to Tertiary plutonic rocks and coeval or younger volcanic rocks (Clautice and others, 1993).
Black shale crops out on the northwest bank of the Kantishna River. At the prospect sites, the black shale contains brecciated zones along low-angle faults. Bond (1985) reported that these brecciated zones contain weak Zn-Cu mineralization.A regional stream-sediment sampling and mapping program in 1975-76 identified geochemical anomalies (Bond, 1985). There are no indications of production.
