Location: This unnamed gold occurrence is located on a ridge south of Kal Creek, about 2.4 miles east-southeast of Jack Wade Junction. The occurrence is in section 10, T. 27 N., R. 21 E., of the Copper River Meridian. The location is only accurate to within 2 miles.
Geology: The rocks along Kal Creek are Paleozoic amphibolite-facies metamorphic rocks that have been intruded by plutons and dikes of probable Jurassic age (Foster, 1976; Szumigala and others, 2002). There is a small area of coarse conglomerate with sparse interbedded sandstone of Tertiary age along Kal Creek. Prindle (1909) reports that gold was found in a conspicuous outcrop of vein quartz and quartzitic schists. The vein was said to be about 1,000 feet long and 50 to 100 feet or more in width and on the ridge south of Kal (Kalamazoo) Creek. The vein was believed by local miners to be the source of gold in the creek. There is no more recent mention of this occurrence. There has been placer gold production on Kal Creek (EA146) and on Squaw Gulch (EA147) downstream of Kal Creek.
