Piezometer reading graphs for each site are also included. Site 1 currently shows the highest pressures <br />with the piezometer in the LL seam varying from approximately 16 psi to 23 psi and the piezometer in <br />the LM seam varying from approximately 25 psi to 30 psi. These reading are currently 20.9 and 28.2 <br />respectively for the LL and LM instruments. Site 2 readings have varied from 11 psi to 15 psi in the LL <br />and 19 psi to 22 psi in the LM. Current Site 2 readings are approximately 15 psi and 22 psi respectively. <br />The piezometers at Site 3 have shown low readings with very little variation during the monitoring <br />period. Current readings at Site 3 are 0 psi and 6 psi respectively for the LL and M seams. The <br />piezometer readings at Site 4 have varied from approximately 15 psi to 19 psi in the L seam and near 0 <br />for the entire monitoring period on the LM seam. Variations in pressures have not been a concern at this <br />time. <br />Sites 1, 3 and 4 include GPS monitoring stations. Historical data for these devices exists but is not <br />currently available due to modifications that have been made, at Trapper's request, regarding the <br />reporting of the data. These stations record displacement in the x (east), y (north) and z (elevation) <br />directions in millimeters. Site 1 has shown the most movement. This site sits on the old natural landslide <br />area. Some surface movement is expected at this site. Current displacements at this site are <br />approximately 50 mm (1.97 inches) in the x direction, 7 mm (0.28 inches) in the y direction and 120 mm <br />(4.8 inches) in the z direction. Site 3 measurements have not been significant with current displacements <br />at -0.1 mm (-0.004 inches) in the x direction, -4.0 mm (-0.16 inches) in the y direction and 6.2 mm (0.24 <br />inches) in the z direction. Site 4, which is proximate to current stripping and blasting operations, <br />currently shows displacements of 8.0 mm (.32 inches) in the x direction, 1.0.5 mm (0.41 inches) in the y <br />direction and 20 mm (0.79 inches) in the z direction. Trapper will send the full displacement histories <br />for these sites with the next report. <br />It is likely that Site 1 will be relocated before the next report as it is in a projected development area. <br />Trapper will be able to salvage the inclinometer and GPS instrumentation from this site and use it at the <br />relocated site. <br />Please contact me if you have any questions. <br />Sincerely, <br />James M.
