|Location and accuracy||Placer claims on Red Creek extend for about 4 miles from the south boundary of sec. 15, T. 25 N., R. 11 E., to the NW1/4 sec. 34, T. 26 N., R. 11 E., Seward Meridian. The site is plotted on Red Creek at an elevation of about 3,850 feet; it is accurate to within 1/2 mile.|
Red Creek drains an area of cobble and boulder conglomerate, siltstone, and shale of the Jurassic Naknek Formation, and sandstone, siltstone, shale, and volcanic rocks of the Talkeetna Formation (Csejtey and others, 1978). The surrounding hills are topped by Tertiary fluviatile conglomerate. The valley gravels are 50 to 500 feet wide and 6 to 40 feet thick; the stream gradient is 70 to 170 feet per mile (Kurtak and others, 1992). Stream-sediment samples collected by the U.S. Bureau of Mines contain up to 0.5 part per million silver and up to 0.0020 ounce of gold per cubic yard. A panned- concentrate sample contains 2.13 ounces of gold per cubic yard (Kurtak and others, 1992).Twelve placer claims were staked by Earle Krinke in the 1980s (Kurtak and others, 1992). A processing plant and camp were located at the mouth of the creek and prospect pits and cuts were dug along the length of the creek. As of January 1, 2000, a block of more than 8 state claims covered this prospect (Northern Associates Inc., written communication, 2001).
