Abstract: The geophysical surveys carried out in the South Bay Mine area since 1992 have established that ground based electromagnetic surveys are effective for both detecting and mapping the migration of plumes of Acid Mine Drainage (AMD) in the groundwater, and for evaluating the effectiveness of the remediation measures that were implemented. During 1995, the electromagnetic surveying was focused in four areas: (1) Mud Lake (2) West of the Tailings (3) South of the Tailings/ Townsite (4) Mine Site Numerous geophysical anomalies were identified, and anomalies with unexplained sources of conductivity were tested during an extensive programme of piezometer installation. This section presents the results of the geophysical surveys in the Mud Lake area and west of the tailings area, along with water quality data obtained from the piezometers that were installed to test geophysical anomalies. These areas are all “exploratory” in nature where the surveys are being conducted for the first time. The survey was carried out step by step, adding lines as was indicated due to anomalies. Those were then used to place piezometers, and confirm or refute the presence of seepage pathways and delineate their extent.
