| Location and accuracy | This site consists of two, northeast-alined, geologically similar occurrences, locally called R-2280 and R-2283, on a northeast-trending ridge at the head of Camp Creek. The coordinates are for the southwestern occurrence (R-2280), in the northest corner of sec. 1, T. 14 S., R. 7 E., Kateel River Meridian. The other occurrence is about two miles to the northeast. The location is accurate within 5 miles. |
Geologic descriptionThese occurrences are small, northeast-aligned gossans two miles apart. The southwestern one (R-2280) consists of scattered float of gossanous breccia in quartz-chlorite schist rubble. One sample contained 400 ppm copper, 400 ppm zinc, 55 ppb gold, and 39 ppm molybdenum. The northeastern one (R-2283) is similar, but the gossanous breccia rubble-crop is gray schistose quartzite, instead of schist. One sample yielded 163 ppm copper and 265 ppm zinc (Flanigan, 1998). Also see NL002 and NL009-011. | |

| Mineral deposit model | Plutonic-related? Pb-Zn deposit. |
| Age of mineralization | Based on similarities with the Paw Print (NL009) occurrence and proximity to the Round Top (NL011) intrusion, these occurrences may be coeval with Round Top intrusion, which is about 73 Ma (Flanigan, 1998). |
| Workings or exploration | This occurrence was discovered by Anaconda Minerals Company in 1980 (Flanigan, 1998). |
