Notes for site visit October 16, 2013: <br />1 arrived on site around 12:30. Gary Harding took me around the site. <br />The mine has received a significant amount of rain over the last week, <br />approximately 1.8 ", the site was very wet. So wet in fact, we didn't <br />walk around very much in either gob pile area. <br />We initially went to the top of gob pile #2. Overall, the site looks <br />good. The top is still graded very well, and there is positive drainage. <br />The Operator is making plans to start bringing gob in and dumping it <br />in N" shaped piles to promote drainage out of the gob. Once the <br />piles have drained, they will be pushed back to the top of the pile and <br />compacted. We couldn't drive to Ditch F -19, but from the haul road <br />up to the mine office, it looks like some rocks had raveled down into <br />the flow line. They will be removed as soon as the site is dried out <br />enough to get equipment over there. Monitoring of that flow line will <br />become a maintenance issue as coverfill from gob pile #3 is being <br />hauled to that location and therefore, rocks, or coverfill, could end up <br />in the flow line again. <br />We met with a contractor about relocating the E. Diversion Ditch <br />higher on the hillside in order to expand the top of gob pile #2. He <br />thinks the ditch can be safely constructed, so I will proceed with a <br />technical revision to be submitted this winter. <br />All of the ponds except for Pond K are holding water and sediment. <br />Pond F was about 2' below the emergency spillway. They are letting <br />the fines settle before attempting to dewater the pond. Fortunately, <br />the next 4 -5 days are forecast to be dry which will help with <br />dewatering all of the ponds, but specifically Pond F. <br />Our next stop was gob pile #3. Gob was actively being dumped while <br />I was on site, and the material was being worked in an effort to get it <br />to dry, but at this point, it is very wet soupy material. The haul road <br />into the site (in the pit area) has been ripped out and relocated. <br />Coverfill was still being salvaged. The contractor estimates at least <br />another two weeks of coverfill salvage before they begin placing and <br />compacting gob in the active placement and compaction area. The <br />location of the underdrain has been staked, but no work has begun. <br />
