5.0 Field Observations <br />' In addition to the structural geology data collected, the following field <br />observations were also used to evaluate the current quarry conditions: <br />1) Significant mining progress has occurred in the quarry since the previous <br />annual report was prepared in April 2005 (LF&A, 2005), primarily in the <br />southern expansion and mid-level areas. <br />2) In the southern expansion area, the fifth bench is currently being reclaimed <br />' (Photo 4), and the sixth is more than halfway mined (Photo 5). An <br />approximately 10-15 foot high bench is currently being excavated along the <br />eastern flank of the southern expansion area below approximately the 6900 <br />foot elevation and is referred to in this report as the seventh bench (Figure <br />' 2 and Photo 6). In the southern expansion area, discontinuities on <br />advancing benches were mapped for east facing exposures only. <br />The middle level has also been mined since the 2005 annual report almost <br />' the entire level being excavated from 6,480-foot to the 6,400-foot elevation <br />(Figure 2 and Photo 7). Rock exposures on advancing faces were mapped <br />' for north facing exposures at this level. <br />' In the main pit, the base elevation of 6,340-feet has not changed since the <br />2003 annual report was prepared. Some mining has continued in the south <br />central part of the main pit and the exposures on the north facing temporary <br />wall were mapped (Figure 2, Station 1; Photo 8). <br />3) The quarry walls appeared to be relatively dry, although judgment cannot <br />be made solely by observing the seepage conditions without the installation <br />' of piezometers. Groundwater flow in the rock mass is primarily in fractures <br />and not through the rock matrix. Noticeably absent is any major seepage in <br /> <br />' -10-
