Location: The approximate location of the Paw Print occurrence is at an elevation of about 1100 feet, approximately 2 miles east of hill 2230, in the SE1/4 sec. 9, T. 14 S., R. 18 E., Kateel River Meridian. The location is accurate within 2 miles.
Geology: The country rocks in the area of the Paw Print occurrence consist of Paleozoic to Proterozoic (?) schist and quartzite (Patton and Moll-Stalcup, 2000). The Paw Print occurrence is at the northeast end of a 4-kilometer-long, northeast-trending linear feature marked by anomalous metal values in silt and soil associated with iron-stained springs or seeps. The seeps and iron-stained streams mark a probable contact between graphitic quartzite and younger, unmetamorphosed mafic volcanic and intrusive rocks. Stream and soil samples contain up to 300 ppm copper, 420 ppm lead, 1645 ppm zinc, 120 ppm molybdenum, 2.1 ppm silver, 10 ppb gold, and more than 1000 ppm arsenic (Flanigan, 1998). Flanigan (1998) suggests that the molybdenum content of this occurrence may link it to the Round Top quartz monzonite intrusive complex (NL011), which has been dated at approximately 75 Ma. Also see NL002, 008, 010, and 011.
Workings: This occurrence was discovered by the Anaconda Mineral Company between 1980 and 1982 (Flanigan, 1998).
Age: Flanigan (1998) suggests that the molybdenum content of this occurrence may link it to the Round Top quartz monzonite intrusive complex (NL011), which has been dated at approximately 75 Ma.
Alteration: Locally conspicuous iron-oxide alteration.
