Abandoned Mine Land (AML) Geochemical Data: Star District, Utah

The Topache-Picacho project is located in the Star Mountain Range, approximately 50 miles north of Cedar City, Utah. The Star Range was historically mined for lead and silver beginning in the 1870s (Krahulec, 2018). The Topache-Picacho samples can be spatially clustered into two groups: the first consists of samples closest to Topache Peak and the second consists of samples closest to Picacho Peak.
From November to December, 2014 and June to July, 2015, the United States Geological Survey (USGS) collected a total of 142 samples from abandoned mine waste piles, channel sediments downslope of waste piles, and background areas. Waste pile, sediment, and background samples were collected in accordance with USGS Standard Operating Procedures for Abandoned Mine Land Sampling (AML SOP). (Marston & Hess, 2016).
