Location: The Jersey prospect is at an elevation of approximately 800 feet, 1/2 mile southwest of Douglas and 1/2 mile north of Paris Creek. It is near the southeast corner of section 35, T. 41 S., R. 67 E. of the Copper River Meridian. The location is accurate.
Geology: The Jersey prospect was discovered in 1896 and was developed by a 85-foot shaft, a drift, and 5 trenches. The deposit consists of quartz vein stringers in black phyllite and felsic phyllite (Wells and others, 1986). The phyllites and the quartz veins contain disseminated pyrite. U.S. Bureau of Mines samples contained up to 1.0 ppm gold (Redman and others, 1989). The rocks in the general area are Upper Jurassic or Cretaceous marine argillite and graywacke, interbedded with andesite or basalt (Brew and Ford, 1985). The bedded rocks are regionally metamorphosed to prehnite-pumpellyite or greenschist grade, and cut by diorite or gabbro dikes and sills.
Workings: The deposit at the Jersey prospect was discovered in 1896 and was developed by a 85-foot shaft, a drift, and 5 trenches.
