Cycle Step 3 - Movement of the processing plant to another <br />area on the perimeter but within the pit. <br />Cycle Step 4 - Return to cycle step 2 for additional open <br />pit mining. <br />Using this cycle the entire pit can be mined without having a <br />permanent location for the processing plant. All materials can be taken <br />while higher terraces that are not used for access to ad its can be <br />reclaimed. Eventually, the processing may be moved underground in a <br />mined out ad it and the bottom of the pit mined and finished. <br />Currently, the quarry is in the Initial Step as the pit is <br />still expanding to its maximum top diameter. 6ahen that stage is reached <br />the plant will be moved from the center of the quarry to a site behind <br />the berm currently under construction. The cycle will then begin to <br />• bring the pit to maximum depth by the time of mining termination. <br />Underground mining is currently being conducted with portals <br />on the west side of the quarry. Once the quarry pit has expanded to its <br />maximum diameter and the depth of the terraced quarry walls is sufficient <br />more adits will be constructed on the north side of the quarry for <br />underground mining of limestone not currently accessible. <br />In effect the mine will be conducted in three phases as <br />follows: <br />Phase 1 - Serm construction, Initial Step in ope:z pit cycle, <br />west side ad its. <br />Phase 2 - Engagement of open pit cycle, north sicie ad its. <br />Phase 3 - Possible placement of processing plant underground, <br />completion of pit, and completion of reclamation. <br /> <br />S-D-3 <br />
