Historic mining of schist-hosted gold has exposed arsenic-bearing rock and discharged arsenic-bearing tailings to a stream which has now become a wetland. Arsenic in soil and wetland sediment is strongly elevated (to >1000 mg/kg) above regional background of 10 mg/kg. Dissolved arsenic concentrations reach nearly 1 mg/L in places.

The majority of porphyry copper-gold and copper-deficient porphyry gold deposits was generated at Pha-nerozoic convergent plate margins (Sillitoe 1991; Vila et al. 1991).
