|Location and accuracy||The Rod (LEA Creek) prospect is at an elevation of about 4,700 feet, on the east side of a south-flowing tributary to Dry Creek. The map site is about 1 mile south of VABM 6463 (Art), in the NW1/4 of sec. 13, T. 11 S., R. 1 E., of the Fairbanks Meridian. The location is accurate to within 1 mile.|
Geologic descriptionThe country rocks at the Rod (LEA Creek) prospect are the Lower Mississippian to Middle Devonian Totatlanika Schist, composed predominantly of felsic and mafic metavolcanic and metavolcaniclastic rocks, pelitic schist, and minor marble (Wilson and others, 1998). The deposit consists of massive-sulfide lenses in schist (www.grayd.com, 1999). The lenses are mainly galena and sphalerite, accompanied by chlorite, quartz, and sericite.
