The orientations of the pit walls follow the previous benches and it is assumed <br />that the azimuths utilized for the 2001 annual report (which relied on the most <br />recent topographic map of the quarry) are representative of the current bench <br />orientations. Figure 1 shows a topographic plan view of the quarry in 2000 <br />modified to approximate mining progress through March 2002. The dip direction <br />' and slope angle utilized to represent the final quarry walls are presented in Table <br />1 below. <br />1 <br />TABLE 1: REPRESENTATIVE QUARRY WALL ORIENTATIONS <br />' Quarry Wall Slope Direction of Wallt,l Slope Angle (deg),~1 <br />East 242 45 <br />' Northeast 186 45 <br />' Northwest 151 45 <br />West 091 45 <br />Southwest 317 45 <br />Southeast 354 45 <br />' Note: 1 -Dip directions are azimuths measured from true north (0°). <br />2 -Dip angles are measured relative to the horizontal. <br />The east, northeast, northwest, and southeast wall orientations apply to the walls <br />forming the perimeter of the main pit. The west and southeast wall orientations <br />are considered applicable to the perimeter walls in both main pit and the upper <br />level. <br />3.0 Field Observations <br />In addition to the field data collected, the following field observations were also <br />used to assess the current quarry conditions: <br />2002 Spec-Agg Annual Report Page 6 <br />
