2. Backfilling - Backfilling of mined areas was done on two small areas in the old lease area. <br />As described in the plan, mining continues in a deposit until the mining limit is reached or the <br />deposit ends. <br />A. Depth of backfilling - Backfilling that was done exhibited previous patterns of <br />achieving greater depths of fill than would normally be expected. Where backfilling <br />was done the land was returned to the original elevation. <br />B. Material used in backfilling - Most of the backfilling has used overburden and <br />subsoils stripped from the site where the filling is being done or at least sites that were <br />near enough to the backfilling that it is still considered to be original material. This is <br />consistent with the method of operation described in the plans. Other sources of <br />material include wash fines from processing plant pond cleaning. <br />C. Maximum, minimum, and average slopes - Finished slopes in all the backfilled, <br />graded and topsoiled areas are rarely even close to the 5:1 limit. Most are in the 7:1 to <br />15:1 or less steep range. Backfilled areas in the last year are almost level (no slope). <br />D. Deviation from original elevation for new backfilled land - Backfilling this year <br />returned the land to its original elevation. <br />3. Processing facilities - Nothing has changed here. <br />4. Access corridors - No change in access corridors. <br />5. New soil and overburden stockpiles - A large stockpile of new overburden was established <br />this last year. It is located immediately south of the active pit and adjacent to where it will be <br />used. A new pit to the south of the main pit was explored and found to contain poor material. <br />This pit may be backfilled in the next year with material from the new stockpile. <br />RECLAMATION ACTIVITY IN THE LAST YEAR: <br />1. Climatic summary of previous year - This was previously discussed elsewhere in the <br />report. <br />2. Topsoiling - Some minor topsoiling was done in the last year, all of it on upland areas that <br />were completed with backfilling. <br />A. Locations of topsoiling - All the topsoiling done in the last year was on the south <br />end of the upland area in the older mined locations immediately west of the main road <br />and near the first cattle guard. Some minor backfilling was done in other locations <br />nearby. Other than the current mining and the plant site, all land east of the main road <br />has been reclaimed. <br />Status report for 2009 <br />due July 15, 2010 Page 6 of 13 <br />
