In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined and over and underlying units over a geographic area that reflects the proposed mine location. After mining, groundwater is restored using a variety of techniques intended to return groundwater quality to as close to baseline as practicable. After groundwater has been restored, groundwater quality is monitored to determine...

This data release presents the results of microanalysis of 2 samples SSD15_01A (1 thin section and 1 composite chip sample), and SSD15_01B (1 thin section). The samples were collected in 2015 by U.S. Geological Survey geologists Bradley Van Gosen and Susan Hall from surface exposures of uranium mineralization in Sulfur Springs Draw, in Martin County, Texas (Van Gosen and Hall, 2017). The samples were collected as part of a field program designed to examine exposures of known uranium mineralization in support of the development of a genetic deposit model for calcrete-type uranium deposits in the Southern High Plains (Hall and others, 2019; Van Gosen and Hall, 2017). This study also contributed to an assessment of...

Grade and tonnage data for calcrete-type surficial uranium deposits found in 11 different countries were compiled. Fifty-eight deposits with reported grade and tonnage, and thirty-five occurrences for which there is no reported resource are tabulated in separate Excel workbook spreadsheets.

Major-element and trace-element concentrations in 76 core samples and seven surface samples of rocks from the Coles Hill uranium deposit and vicinity, Pittsylvania County, south-central Virginia are presented as tabular digital data. The Coles Hill deposit is the largest unmined uranium deposit in the United States. The data were collected to 1) characterize the chemistry of variably uranium-mineralized rock units within the deposit and 2) to compare with the chemistry of un-mineralized surface exposures of the same rock units. Cores were sampled in 2017 by U.S. Geological Survey (USGS) personnel from archived historical collections of the Virginia Museum of Natural History. Core samples were selected based on measurable...
