Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
Geochemical data for all solid sample media, along with mineralogical data, and results of weathering experiments on Valzinco tailings and field experiments on sediment accumulation in Knights Branch.
Geochemical analysis of water samples to provide a pre-reclamation assessment of seasonal variations of acid and metal concentrations in Knight's Branch help evaluate the reclamation project.
Details of materials and geologic environments in an area where a long history of mining has enriched stream sediments in silver, lead, zinc, arsenic, antimony and mercury, copper, cadmium, manganese, and iron.
Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
An environmental impact study is done for the abandoned Ely copper mine. The extent of contamination is studyed along with the type and chemical composition of the mine waste piles.
Sampling procedures, analytical methodologies, and results to assess the potential for mine waste and drainage to have an adverse impact on aquatic ecosystems, on drinking- water supplies, and to human health
Geochemical analysis of mine dumps, mill tailings, mine drainage, and surface waters indicate contamination from these historic mines is generally less than that asserted or suggested by some geochemical models
Geological, geochemical, hydrologic, and biological observations combined with geographic framework data, supporting a multidisciplinary assessment of the impact of historic mining in this area.
Summary of data obtained from field sampling of mine tailings and waste rock and water and sediment in regional springs and tributaries that drain from the mine area into Bear Creek. Ground-water springs are also potential sources of mercury here.
