be a result the beginning of slope failure, or it may be the result of excessive rain causing fine <br />sediments to wash down into the coarse-grained material below. <br />Halogeton is an ongoing problem throughout the area and is the main weed of concern in the <br />area. Lack of mine associated traffic has increased the area available for growth. The vent hole <br />associated with the Topaz mine was in good shape, with the exception of the abundance of <br />Halogeton. <br />We also drove by the reclaimed GMG mine just to take a look so that I would be familiar with it. <br />The site was reclaimed. <br />Notes and photographs from each mine site are included in the order in which they were taken <br />and are attached to this report. <br />Action Items <br />1) Continue with herbicide application on site. The frequency of application may need to be <br />increased. <br />2) Monitor the fissure in Topaz dump for signs of mass movement. Determine if it is from <br />infiltration of fines or from mass movement. If it is from mass movement, then mitigation <br />methods will need to be devised. Denison should discus with BLM. <br />3) Check storm water runoff features on a frequent basis to ensure they continue to function <br />properly - for as long as the monsoon rainfall pattern continues. Maintain as needed. <br />4) Continue to monitor toe of dumps for signs of seepage, after the monsoonal cycle has subsided. <br />5) Secure the storage shed on the Carnation Mine. <br />6) Clean up additional junk trash and tires identified at the site. This does not need to be done right <br />away, but can wait until the mine is reopened, or the decision is made to idle the site long-term. <br />7) The Topaz Vent area should be re-seeded after it has been sprayed. <br />G?5 <br />James Blair <br />DPLO Geologist <br />August 24, 2010 <br />Page 2 of 34
