r ' # <br /> tank in the filter building. Very wet material cannot be accepted for compaction <br /> in the piles. Required compaction in the two piles must be achieved at all times. <br /> We cannot risk lack of compaction of the tailings which could result in a failure <br /> of the tailings embankment. <br /> e- Average moisture content testing procedure using the provided protocol <br /> supplement is required(TMPool).Moisture testing is to be performed by trained <br /> tails management personnel using the ICT MPKit-4o6 Soil Moisture Instant <br /> Reading Kit. This information is provided in Appendix C. <br /> f- Tests sheets are provided at the end of this manual which should be filled out for <br /> every test and kept on site at the back of the bound Manual. <br /> g- If,for any reason, mill personnel believe that there is a significant change in <br /> chemistry or the size consist of the tails, the mine management and the engineer <br /> that certifies the tailings embankment must be notified to determine if any further <br /> action or testing is required. This is important since the tailings must be inert. <br /> h- SPLP tests of the tailings are to be done every 6 months or sooner if there is reason <br /> to believe that the tailings have changed in chemistry or size consist. These tests <br /> should be performed by the Surface Mine Manager or other qualified personnel. <br /> i- Tailings from the mill must not be overloaded in such a way that spillage occurs. <br /> Any spillage of tails must be removed and taken to the proper waste pile area. <br /> 3. Mixing Waste Rock with Tailings for Proper Compaction <br /> Waste rock is any rock produced in the mine that is not processed in the mill. This <br /> material is generally blasted rock less than 12 inches in size down to silt and clay size <br /> material. The amount of this material produced will vary depending upon the activities <br /> taking place in the mine. Ramping or blasting development tunnels and raises outside the <br /> veins produce waste rock. There will be other periods of time when no waste rock is <br /> produced. Since the waste rock may have a larger percentage of large rock,it is important <br /> 4 <br />
