17)(Optional) Please provide additional information about the Mine Plan: Strips will be cut on the 9.9 acre permitted area,with a maximum of 1.5 acre disturbed during mining phases with a maximum disturbance of 2.5 acres including processing areas,ponds,roads,etc.Material will be excavated and stockpiled in previous disturbed area adjacent to cuts and run through portable wash-plant.Topsoil,will be stockpiled at the western end of each cut.Tailings from washplant will then be moved back to the mined cut.Mining will commence in a direction from North to South,filling cuts with tailings and moving on. Upon completion disturbed area will be graded and restored to previous contours.An excavator and front loader will be used for the excavation and processing.Hired excavator contractor will be used for grading. Including the following: (1)(b)Topsoil not immediately reclaimed to be covered w.erosion control blankets (d)Deposit averages 72'in depth (e)No permanent structures on site.Shipping containers will be used to house supplies,including workshop to maintain equipment and gold recovery.Mobile office and RV will be placed on previously disturbed ground. (f)Stripped ground will not exceed 100'in width and 600'in length.Stockpiled ore material will not exceed a 100'x100' footprint and tailings will also not exceed a 150'x100'footprint.Ongoing reclamation to follow immediately after running of the material through the washplant.Ponds will be placed at existing dam feature.Pond dimension(triangular) 60'x100'x120'with a depth of 8'(150,000 gallons).Pond will not use a liner,washing of the material creates a seal to hold the water.Only one pond will be open at a time.The north pond will be created first to cover the north section of mining. Once mining the north section will be complete,the north pond's water will be pumped over to create the south pond. (g)The mine will be accessed via an existing spur off of Moffat County Road 88.The spur is approximately 105'in length and 15'in width.No improvements to the this spur will be necessary.The spur accesses a previously worked pit. (h)The West Side P►acer will use approximately 12 acre feet of water per annum. (j)No injury to existing water rights,area is not appropriated.All water taken from the well will be placed back into the earth. (K)Rapid Thickener and Flocculant: The rapid thickener is a tank with a rotating rake that is designed to remove sediment,primarily clays and sub 200 mesh particles so that water can be recycled for continual process water use.See attached architectural diagrams and photos provided.Updated Mine Plan and Map reflect these changes. The rapid thickener dramaticallyreduces the water requirement for the West Side Placer.Water is constantly recycled.The thickener underflow,containing consumed flocculant is discharged into north water pond.The underflow is primarily clays and fine sand particles.The flocculant is biodegradable and non toxic.The discharge is reclaimed from the pond and added to processed materials for reclamation.The consumed flocculant is non toxic and biodegradable. The rapid thickener uses a non toxic flocculant-DAF 30.See attached MSDS.DAF 30 does not contain any hazardous components according to OSHA 29 CFR 1910.1200.The DAF 30 is diluted to 1 ppm after being introduced into a mixing tank and then into a holding tank that is used to inject the flocculant into the process water before the thickener. Mixing tank is 500 gallons,while holding tanks is 3000 gallons.Spills will be cleaned up with absorbent material and disposed of in accordance to all applicable laws. Dry flocculant is double contained and stored with a Connex shipping container.
