The risk potential for acid rock drainage and metal leaching is presented for various rock types found in the mine study area. Extensive testing was conducted to determine geochemical properties. Tests included a wide variety of field, static, and kinetic methods that address reaction rates over time under conditions that include exposure to air, alternating cycles of wetting and drying, and saturated conditions.
- The geochemistry studies at Pebble include nearly 1,000 rock samples from the deposit area.
