also submerged within the pond which required dewatering. Once located, flow from the <br />pipe was successfully stopped. The end of the pipe appeared consistent with a steel casing <br />pipe commonly used for exploratory drilling and coring. A second and successful attempt at <br />inserting a special camera down the length of the steel pipe verified that this was an <br />exploratory core hole. <br />Transducer telemetry data used to monitor water levels in the mine pool showed a drop in the <br />mine pool water level during the pipe separation release. Once the pipe flow was stopped, <br />the mine pool water level rebounded upwards. Several weeks later, when the packer <br />unexpectedly depressurized and a second release occurred, the mine pool level again dropped <br />until the leak was stopped. <br />These data (shown below) point to a hydraulic connection between water in the exploratory <br />core hole and the mine pool, and also demonstrate that any other measurable leaks or seepage <br />from the mine pool (in excess of normal seasonal groundwater fluctuations) would be <br />reflected in the telemetry data monitoring mine pool level. The reasons for significant <br />differences in water chemistry between water from the exploratory core hole and the mine <br />pool remain unclear. <br />Telemetry Data <br /> 6586 <br /> 1 <br />N 6585 <br /> ? <br />z <br /> <br />_ Pipe Flow Contained Packer Depressurized <br /> (10.7-10 @ 1:20 p.m.) <br />1117.10} <br /> <br /> 6584 <br />t <br />i <br /> ? <br />W Pipe Joint Separation i <br /> -1(9-29-110 (d - 2 p.m.? + <br /> <br />m t <br />C ? <br /> 6583 <br /> <br /> Pipe Flow Contained <br /> (11-10-10} <br /> <br /> 6582 <br /> 9119/10 9/25110 10/1/10 10!7/10 10/13/10 10/19/10 10!25/10 10/31/10 11/6/10 11/12/10 11/18/10 <br />6
