<br />* 2011 -IN6, 2011 -IN7 and 2011 -IN8 were incorporated into the slope monitoring system. Applied Geomechanics placed inclinometer sensors at the K or LK, L or LL and R seam intervals and
<br />piezometer sensors at the L or LL and M or LM seam intervals. A grout of cement and powder bentonite was used between the piezometer sensors.
<br />** The E pit drill holes were developed into inclinometer holes, except for 3A.
<br />"" Bentonite coated pellets are used when water is present and bentonite chips are used in dry intervals of the drill hole.
