Both natural and human-related metal mobilization may affect streams. In this photo drainage from a mine enters Cement Creek, near Silverton, Colorado, adjacent to a mound of iron minerals that have likely been forming naturally for thousands of years. Detailed isotopic studies may help to differentiate natural and human-related contamination.

Draining Mines
Draining mines provide consistent discharge of rare earth element concentrations

Draining mines provide consistent discharge of rare earth element concentrations

Draining mines provide consistent discharge and have elevated rare earth element (REE) concentrations, potentially providing opportunities for direct metal production.
