Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
Iron ore containing elevated concentrations of trace metals was smelted here during 113 years of operation (1771-1883). We sampled a variety of materials nearby to determine the amount of metals such as arsenic, chromium, copper, lead, and zinc.
