It appears that there is a zone of some gold in the gravel from the surface to a depth of approxi- <br />mately 20 -30 feet, followed by a barren gravel zone of 30-40 feet followed by a zone of up to 25 <br />feet that contains a higher percentage of gold. The barren zone will be used to backfill previous pits <br />and the other material will be sent to the plant for processing. Some of the washed gravel will also <br />be used for backfilling and other material may be further crushed and screened for gravel product <br />sale. <br />Once the initial pits have been excavated, barren material and washed gravel will be used to'back- <br />fill previous pits. The maximum amount of pit that requires backfilling will be limited to 20,000 <br />cubic yards. <br />The pre-2012 highwall of approximately 60 feet height which was located at the south end of the <br />infiltration pond became the settling pond for the processing plant and the highwall was filled in <br />from the ongoing processing and has now been reclaimed as of the end of 2014. <br />Section 5.0 Topsoil Removal and Stockpiling <br />Much of the site was disturbed over a century ago and no topsoil was salvaged from this operation. <br />Since the operation was permitted in 1984, two main topsoil piles have been created. <br />Greg Lewicki, P.E. conducted an inspection on October 1, 2014 with a handheld Garmin GPS <br />which reported an accuracy of 11 -16 feet on site. Over 200 points were taken of the perimeter of <br />the topsoil stockpiles as well as the perimeter of the disturbance. These points were later trans- <br />ferred to the registered cad map in the State Plane coordinate system and were found to be suffi- <br />ciently accurate to make topsoil quantity estimates. The attached Topsoil Inventory Table was de- <br />veloped by Greg Lewicki to evaluate the topsoil amounts in each of 6 areas where topsoil is <br />available on site. The areas were measured in cad after adding the gps points. The heights of the <br />piles were measured with a tape and the average heights were estimated. There are 5 stockpile lo- <br />cations on site and one area that has not yet been stripped (Area 3). This area was spot checked <br />Gloria Z Mine TR -03 2015 14 <br />
