| Location and accuracy | Near glacial headwaters of Peters Creek a tributary to Knik Arm, above southwestern bank of creek. NW1/4SW1/4 sec. 4, T. 13 N., R. 2 E., of the Seward Meridian. Accurate within 1000 ft. Locality 50 in Cobb (1972) and locality 39 of MacKevett and Holloway, 1977. |
Geologic descriptionCapps (1916) reports quartz veins present in Mesozoic age greenstone and greenstone tuff with minor amounts of interbedded shale of the McHugh Complex. The thin, auriferous quartz veins also carry pyrite, galena, and chalcopyrite. One 2 inch thick vein that strikes N 60 W and dips 75 SW is intersected by an 8 inch thick vein that strikes N 77 W and dips 60 N. Assays as high as 1.84 oz/ton Au. | |

| Mineral deposit model | Low-sulfide Au-quartz veins? (Cox and Singer, 1986; model 36a?) or Chugach-type low-sulfide Au-quartz vein 36a.1? (Bliss, 1992; model 36a.1?). |
| Mineral deposit model number | 36a? or 36a.1? |
| Age of mineralization | Mesozoic or younger. |
| Workings or exploration | Explored by several short adits. Assays as high as 1.84 oz/ton Au, reported as $38/ton, with gold valued at $20.67/oz (Capps, 1916). Some ore may have been mined, but not shipped, in 1917 (Capps, 1919). Martin (1920) reported discovery of chromite, in 1918, in Peters Creek. Rose (1966) reported a local prospector reported finding jade in Peters Creek. |
