I'm glad to hear [hat you found [he "alternative" surface reclamation <br />documents. As we discussed earlier, this will have a big impact on the cost to reclaim <br />this site. <br />I will try to answer some of your questions about this site. Virtually all of the on site <br />rubble has been backfilled into the mined area. The top two plus feet has been covered <br />with dirt from the over burden pile and graded to the final grade. The slopes of the <br />backfilled area are at the natural angle of repose (probably about 2 horizontal to 1 <br />vertical). As more rubble is brought to the site it will be pushed over these same slopes <br />so there is no advantage to flattening them at this time. This work would need to be <br />covered by the reclamation bond. I believe that this task could be done with a Cat 320 <br />Excavator in about two days. <br />Once the current stockpiles of gravel are used up, we will continue mining and the size of <br />the pond may increase, However, the amount of work to reclaim the edge of the pond <br />will not change very much because of the on going back filling operations. <br />I have included some pictures [hat may help you to see what the pit looks like now. I <br />have also revised your cost summary form to show my "best guess" a[ what it would cost <br />to reclaim this site. I hope this information is helpful in your new bond recalculation. If <br />you have any questions please call. <br />Sincerely, <br />~~;=~ <br />Alan Parkerson <br /> <br />
