Gold geochemical anomaly in the Cortez district, Nevada

An area in the Cortez district, Nevada, previously established to be anomalous in arsenic, antimony, and tungsten has been found to be anomalous also in mercury and gold. Samples from narrow quartz veins, calcite veins, and shear zones in partially silicified limestone in the lower plate of the Roberts thrust fault (Cortez window) contain as much as 3.4 ounces gold per ton. The richest samples are from an outcrop, about 100 feet long, surrounded by gravels. Their economic significance is yet to be established.

Copper determinations on samples of alluvium and caliche from the rocky Range, Beaver County, Utah

A study of the distribution of copper in transported alluvium on a pediment of the Rocky Range, Beaver County, Utah, undertaken to determine whether known copper deposits in bedrock concealed by alluvium could be detected by geochemical methods, was reported in Geological Survey Research 1960 ( Erickson, R.L., and Marrenzino, A.P., 1960, Geochemical prosecting for copper in the Rocky Range, Beaver County, Utah; U.S. Geol. Survey Prof. Paper 400-B, p. B98-E101). The attached map and table supplement that paper by giving the locations at which the samples were collected and the analytical determinations of copper in the samples.
