4.0 Field Observations <br />In addition to the structural geology data collected, the following field observations were <br />also used to evaluate the current quarry conditions: <br />1) Significant mining progress has occurred in the main pit of the quarry since the <br />previous annual report was prepared in February 2007 (LF&A, 2007). In the main <br />pit, the base elevation of 6,340-feet has been deepened around the area of the <br />new sump by approximately a 15 foot depth to an estimated elevation of 6,325 feet <br />(Photo 1). Discontinuities along the east and north facing exposures were mapped <br />during this study (Figure 2; Station 1). <br />2) The mid-level has been almost completely excavated with a small portion along the <br />eastern to southeastern margin remaining. This remnant of the middle bench <br />remains along the southeastern part of the main pit and is currently being <br />excavated (Photo 6). Access to this area for data collection was not permitted due <br />to the continuous excavation and equipment moving in and out. <br />3) In the southern expansion area, the sixth bench is being reclaimed as the seventh <br />is starting to be excavated (Photo 2). The seventh bench is being mined starting <br />from the southern side of this level (Photo 5) and working to the north. <br />Discontinuities on advancing benches were mapped from both. north and south <br />facing exposures. <br />4) The quarry walls appeared to be relatively dry and noticeably absent is any major <br />seepage in the southwest corner of the main pit, which had been documented in <br />prior reports. <br />5) Two sump pumps are now utilized for controlling water in the main pit. Both sump <br />pits were noted to contain water and are being used regularly. A discussion with <br />the driller onsite determined that water levels are being maintained just below the <br />6,325 foot elevation in the main pit by pumping. The driller noted that with the new <br />-8-
