Ground- and surface-water samples were collected in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and understand factors controlling the discharge of metal-rich waters from the mine.

Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff.

Helium, neon, and argon isotopic compositions contained in fluid inclusions in 25 samples from these mineral deposits. Four mineral separates from the Butte Main Stage vein deposit and two from the Bingham pyrite-enargite vein deposits were also analyzed. Includes some hand samples from underground mine workings and some from mine tailings piles and pits. Data are provided in CSV format.

Environmental tracer data from surface water and groundwater samples to date groundwater and define groundwater flow paths and recharge sources in Redwell Basin. Data are provided in CSV and shapefile formats.

Geological and borehole geophysical data and observations collected to characterize the basin and its surface and groundwater flow systems with primary focus on the physical characteristics of the fault vein, related mine workings, and surrounding bedrock

Stream water, groundwater, and ferricrete samples were collected and analyzed to constrain the location of a possible concealed mineral occurrence. Data are provided in CSV and shapefile formats.

Chemical data from stream water, groundwater, and soil samples collected in 2019 and 2020 in this area. Data from a tracer study is included as tool for understanding sources and loading rates of metals affecting stream water quality in a watershed affected by legacy mining and natural sulfide-weathering. Data are provided in CSV format.

Stream water chemistry and streamflow data collected from 28 sites located throughout Colorado, USA. The sampled streams all drain high-elevation mountain watersheds in areas where the bedrock is hydrothermally altered and contains abundant sulfide minerals. Data are provided in CSV format.

Inorganic chemical analysis of surface- and groundwater and springs in this area to understand natural versus anthropogenic inputs from mineralized and hydrothermally altered areas. Data are provided in Esri file geodatabase, CSV, and shapefile formats.

To help understand the hydrogeologic controls in the basin and how they affect surface and groundwater interactions with nearby mine workings, electrical resistivity profile, self–potential, and magnetic measurement data are provided herein.
