Location: The only published location for this prospect is a small-scale map of Maas and others (1991). There is a group of claims staked at the site, and apparently considerable exploration, including drilling, was done on the ridge east of the headwaters of Old Franks Creek. Somewhat arbitrarily, the site is plotted at the high point of the ridge - which is locally called Franks Ridge - about 0.3 mile (0.48 km) east of the center of section 23, T. 75 S., R. 84 E. The exploration may extend for a mile or more from this location.
Geology: Maas and others (1991) indicate that volcanogenic, massive-sulfide mineralization was found in 1981 along the prominent ridge east of the headwaters of Old Franks Creek. The area was explored by Exxon Minerals Corporation, who staked a group of claims and did extensive work, including drilling. Maas and others (1991) collected 5 samples in the area. The best contained 0.14 parts per million (ppm) gold, 1.6 ppm silver, and 703 ppm copper; most had negligible metal values. As mapped by Eberlein and others (1983), the rocks in the area are basaltic and andesitic volcanic rocks of the Descon Formation of Silurian and Ordovician age.
Workings: Exxon Minerals Corporation staked a group of claims in 1981 and did extensive work, including drilling.
