' ~ no clear sheaz surface is defined. A total displacement of 1 inch has been recorded at this location <br />since 2000 - half of this occurring in the past quarter. <br />' The movement recorded at this location is a concern due to its close proximity to the proposed <br />parking lot and existing mine infrastructure. It is recommended that additional surface mirrors be <br />placed on the decline south of the proposed pazking lot to keep a check on surface movements in <br />this area. <br />MB-2 Pond: <br />Inclinometer I02-50 has shown an increase in displacement during the 2vd quarter by up to 0.4 <br />' inches. A total displacement of up to 1.5 inches has been measured at this location since 2003. The <br />movement recorded at this location is clearly defined by a sheaz plane located at approximately 48 <br />feet below the ground surface. <br />The stability of this area will be checked during the 2006 on site structural review and <br />recommendations will be made with respect to remedial measures (if any) that aze required to <br />' ensure stability. <br />Bart Engineering Company 2n0 Quarter 2006 <br />06126-031 Geotechnical Monitoring <br />
