|Location and accuracy||The approximate location of this occurrence, informally called 'R-0582 gossan,' is about 2 miles northeast of upper Eddy Creek. For this record, the site is plotted in the southwest corner of sec. 28, T. 14 S., R. 7 E., Kateel River Meridian. The location is accurate within 5 miles.|
This occurrence consists of scattered gossan in variably graphitic quartz schist adjacent to a greenstone(?) dike (Flanigan, 1998). Seven rock samples contained up to 191 ppm copper, 373 ppm zinc, 1.1 ppm silver, and 62 ppm molybdenum. Flanigan (1998) suggests that this occurrence is probably related to the Round Top (NL011) quartz monzonite intrusive complex, for which K-Ar and Ar/Ar dates indicate cooling at approximately 75 Ma.Also see NL002, 008, 010, and 011.
