Senate Prospect, Chichagof District, Sitka Borough, Alaska, USA

This page is currently not sponsored. Click here to sponsor this page.
 
 
The prospect is in West Chichagof-Yakobi Wilderness.
Location: The Senate prospect is at an elevation of about 100 feet, 0.3 mile north of the south tip of Hill Island. The prospect is 0.2 mile northeast of the southwest corner of sec. 1, T. 48 S., R. 56 E. It is location P-53 of Bittenbender and others (1999) and MAS no. 0021140109 (U.S. Bureau of Land Management, 2002). The location probably is accurate within about 0.5 mile.
Geology: Johnson and Karl (1985) map the rocks in the area of this prospect as hornfelsed, Cretaceous graywacke and argillite containing sparse, lenticular beds of recrystallized basalt ('greenstone'). The formation is cut by many steeply-dipping, mainly northwest-striking faults. Bittenbender and others (1999), citing Still and Weir (1981), describe this prospect as a copper-bearing, volcanogenic massive sulfide deposit hosted in greenstone. They do not specify the ore mineral(s), but they probably include chalcopyrite, which occurs in similar deposits nearby (for example, SI075).
Age: If the prospect is a volcanogenic massive sulfide deposit, it probably is Cretaceous, the age of the greenstone host rock.

Commodities (Major) - Cu
Development Status: Undetermined.
Deposit Model: Volcanogenic massive sulfide deposit?
