Processes Controlling Groundwater Quality in Uranium In-Situ Recovery (ISR) Mining
The project's primary objective is to evaluate the reducing capacity of an aquifer down-gradient of a roll-front ore zone to assess the mobility of uranium and other associated elements (e.g. arsenic, selenium, molybdenum, and sulfur). Assessing the reducing capacity of the aquifer requires characterization of the mineralogy, geochemistry, and microbiology and their variation across the aquifer.
Geochemical Signatures of Covered Mineral Deposits in the Northern Midcontinent
We are evaluating the potential of geochemical prospecting techniques that have shown promise in other covered terranes for mineral exploration in the northern midcontinent of the U.S. Novel components will be added to these methods with the objective of method advancement and improving our understanding of processes controlling the transmission of unique geochemical signatures from buried mineral...
USGS Abandoned Mine Lands Initiative
The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S. Department of the Interior and the U.S...
