Soil and sediment samples collected along Hazeltine Creek by Mount Polley Mining Corporation between Sept. 3 and Oct. 3, 2014, are consistent with samples taken by the Ministry of Environment on September 4, 2014.
Mount Polley Mining Corporation collected a total of 108 soil samples from 18 different locations in the spill impact area between the tailings storage facility and Quesnel Lake. Both tailings and native soils were tested at an independent lab for exceedances of the contaminated sites regulation (CSR) Urban Park Land Use standard.
Tailings samples showed exceedances for total copper and vanadium, with a single sample indicating an exceedance for total arsenic. No other metals reported in the tailings samples exceeded the CSR standards. These results are expected due to the known quality of tailings stored in the tailings storage facility when it breached.
