Location: This record represents approximately located placer gold prospects and occurrences in Melozimoran Creek. The site is on the upper part of the creek, between the junctions of Grimm and Webories creeks, in the south half of section 16, T. 7 N., R. 26 W., of the Fairbanks Meridian. The prospects are referred to in Cobb (1977), and the site corresponds to location 26 of Eberlein and others (1977). This site roughly corresponds to the U.S. Bureau of Land Management location for Melozimoran Creek (MAS number 0020480130).
Geology: Bedrock in the area of Melozimoran Creek consists of Cretaceous granitic rocks, and of lower Paleozoic quartzite and minor mafic meta-igneous rocks cut by barren, lenticular quartz veins (Eberlein and others, 1977; Chapman and others, 1982). Original bedding is obliterated in most places, but appears to be parallel to schistosity, which dips north more steeply than it does on the south flank of Moran Dome (Chapman and others, 1982). Coarsely crystalline to porphyritic granite locally underlies the ridges on the north side of Webories and Grimm creeks. Alluvium is largely confined to the floor of the modern valley. Prospect pits dug from 1913 to 1918 reportedly yielded a little gold and cassiterite (Martin, 1920). Claims were staked in the Grimm and Webories creeks area during 1943, but there was no production or significant development. Thirteen test pits dug by the U.S. Geological Survey in 1943 near the junction of Melozimoran and Webories creeks failed to find cassiterite or gold in either the bench or the modern stream gravels, but only one pit reached bedrock (at a depth of 6.5 feet) (Chapman and others, 1963). Twelve feet of gravel overlies bedrock in a prospect pit on Webories Creek a short distance above its mouth.
