Appendix A - DRMS Form 2 Public <br />Colorado Plateau Partners LLC - Bush Canyon Project 2009 NOI <br />Some of the access trails and drill pads may require some cutting of brush, tree limbs and <br />perhaps the removal of a specific pinion or juniper tree. Cut material will be temporarily placed <br />in a pile or piles adjacent to the access trail or drill site, and then scattered back over the trail or <br />site during; reclamation. See Attachment B for a photo record of the proposed drill sites and <br />access trails. <br />Drill Hole Abandonment <br />A) Plugging Procedure <br />- Dry or Damp Hole - The drill hole will be backfilled as much as possible with <br />cuttings, using the mineralized material first. After backfilling to within about 5 <br />feet from the surface, a spray foam plug or concrete plug will be brought to within <br />about 2 feet of the surface. The remainder of the hole to the surface will be filled <br />with soil and cuttings. <br />- Wet Hole - Non-flowing Aquifer. While not expected to occur, the hole will be <br />backfilled with a thick bentonitic mud with a > 50 second viscosity to a point 50 <br />feet above the static water level. The mud will be pumped to the bottom of the <br />hole through the drill pipe and the pipe will be periodically withdrawn as the mud <br />level rises in the hole. If closure occurs when the drill rig is not available, <br />3/8"bentonite chips will be added to the hole in a manner as to avoid bridging <br />until the bentonite chip backfill column is at least 50 feet above the static water <br />level. The remainder of the hole will be backfilled as per a dry or damp hole. <br />- Wet Hole - Flowing Aquifer. While considered highly unlikely, if a flowing <br />aquifer is penetrated, then drilling will pause and the permitting agencies will be <br />consulted for recommended abandonment methods. <br />B) Surface Restoration - To the extent possible, remaining drill cuttings will be placed <br />into the containment pit for burial. The disturbed ground will be graded and an <br />approved seed mixture (See Attachment C) will be broadcast immediately following <br />reclamation <br />Estimated Reclamation Costs <br />A) Estimated Cost of Drill Hole Abandonment. - The estimated cost of backfilling the <br />proposed drill holes is $1.25/ft. <br />B) Estimated Cost of Surface Restoration - Estimated cost of the surface restoration is <br />approximately $400.00 per hole. <br />Costs include all materials, labor, equipment, mob-demob, contractors overhead, profit and State <br />supervision charges. <br />Total reclamation cost is estimated at $3,100. <br />Page 3 of 4
