Regional tracts of land where the geology is permissive for the occurrence of undiscovered porphyry copper deposits, with probabilistic estimates of undiscovered resources, along with tables of discovered deposits and prospects.
Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
Groundwater geochemistry data from samples that were collected in June 2011 to better understand the hydrogeologic system in the area surrounding the proposed mine site.
Detailed chemical and isotopic analysis of host and associated rocks within an area that is currently the largest producer of gold in the US. Part of a study of the hydrothermal activity leading to the formation of these gold deposits.
Water samples near this abandoned mine were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.
